MESSAGE
It is our great pleasure to welcome all the participants to the 1st Korea – Québec – France workshop at Yonsei University, Seoul. This event will focus on nanomaterials and advanced functional materials among other key enabling technologies. It will be the perfect opportunity to meet dynamic top research teams of each country and to learn about the most recent scientific developments achieved. This meeting will aim more specifically at the establishment of collaborations and international partnerships for enhancing the cohesion among the academic and industrial researchers present and by seeking new strategic collaborative projects. Moreover, this event will foster existing collaborations and create new ones between academic and industrial researchers who involved in applied research and development of advanced functional materials. This workshop also provide an excellent opportunity to find out new ways to facilitate the international exchange of highly qualified personnel (graduate students and postdoctoral researchers) between Korea, Québec and France.
New materials and optimized materials form basis of roughly two thirds of all innovations, because of this, new (nano)materials have an tremendous impact on future technological advancement. It involves an increasing res-ponsibility to tackle our global societal challenges (eg. Environment, Energy and Health) and to find sustainable solutions. Thus, the development of (nano)materials might be the major part of the next disruptive innovation. Due to its interdisciplinary nature, nanoscience and nanotechnology creates new synergic interactions between scientists and new impulses for the development of innovative materials and their applications. That’s why the scientific Québec and French missions as well as Korean hosts want to emphasis of the synthesis of new inorganic and organics and target specific partnerships which help to obtain better understanding of the materials.
May all participants enjoy this exchange of innovative ideas and have a vivid and exciting time at this workshop.

Abstract
Decreasing the cost of organic semiconductors using novel reactions
As electronics are increasingly present into our everyday life, new technologies are required to produce flexible, lighter and low-cost devices to be easily integrated into everyday objects to create a smarter future. To help bring these new technologies to life, Brilliant Matters is producing carbon-based semiconductors that offer all this and more. With promising results in photovoltaics and transistors and the successful commercialization of organic light-emitting diode displays, these technologies offer a bright future to electronics. There are, however, some hinderers preventing a mass market penetration in certain applications, most notably the currently high cost of the active materials due to their complex synthesis. A new method of production, the direct (hetero) arylation, was recently developed to overcome such limitations. It enables a more cost- and time-efficient production without generating toxic wastes. Through this patented technology, Brilliant Matters offers a solution to help enable these technologies in new markets.

Abstract
Pi-conjugated structures and applications of thereof: beyond the solution
Nowadays, both control of the molecular growth and surface arrangement are of crucial interest for the foreseen optoelectronic applications and constitute a field in full expansion at the interface of physics, chemistry and biology. The main bottom-up approaches make possible to access to unique materials whose properties are adjustable by controlling the arrangement of the molecules onto the substrate. To this aim, supramolecular chemistry constitutes an extraordinary synthetic tool for developing new materials and / or stabilizing molecules that can be manipulated at the nanoscale. Beyond the intermolecular non covalent interactions encountered in solution or solid state, the understanding of the interactions with the substrate is a crucial parameter that will guide the growth of molecules and consequently the morphology and properties of the material.
We will present herein the contribution of supramolecular chemistry in the control of the growth and surface proper-ties of original organic pi-conjugated structures that are currently developed at CINaM laboratory and that can be used in optoelectronic devices.

Abstract
Tumor-targeting smart nanomedicines for enhanced drug release
Nanoscale platforms have been developed to improve the delivery and biodistribution of small drug therapeu-tics to targeted tumors in chemotherapy. In particular, self-assembled micellar aggregates based on amphiphilic block copolymers exhibiting stimuli-responsive degradation (SRD) have been extensively explored as promising nanocarriers for tumor-targeting drug delivery applications. SRD-exhibiting nanocarriers are stable under physio-logical conditions during blood circulation; however, they can be dissociated in a controlled fashion, thus leading to enhanced release of encapsulated drugs as cellular components provide the appropriate stimuli to trigger biode-gradation in microenvironments of tumors and inside cancer cells. Our group has put significant efforts to design and develop various strategies to synthesize novel reduction-responsive block copolymer-based nanocarriers with varying densities of disulfide linkages positioned at single and dual locations. Recently, we have focused on an effective SRD strategy that centers on the development of new intracellular nanocarriers having multiple stimuli- responsive cleavable linkages at multiple locations (denoted as multi-location multiple SRD (ML-MSRD) strategy). This strategy dramatically increases versatility since responses to each stimulus can independently and precisely regulate release of encapsulated biomolecules at several locations.

Abstract
Versatile use of tetrazine derivatives to functionalize graphene sheets. Applications in electrochemical energy storage an electrocatalysis.
Graphene has been the scope of a lot of investigations due to its promising applications in many fields. Graphene sheets can be easily produced from graphite by exfoliation and reduction thermal processes (Hummer’s method). This allows one to have a starting material with various carbon over oxygen ratios corresponding to structures varying from graphene oxide (GO) to more or less reduced graphene (rGO). Our goal is to functionalize these sheets, on one hand to avoid restacking in the case of reduced graphene and on the other hand to introduce new functio-nalities in view of making nanocomposites. Tetrazines are small aromatic molecules with versatile reactivity making them able to react with all these kinds of graphene sheets, either through cycloaddition (on rGO) or nucleophilic substitutions (on GO). This opens new routes to engage the functionalized graphene in further reactions to design composites, either with conducting polymers to make supercapacitors a or with nanoparticles toward electroca-talysis. Several examples will be described in that framework illustrating the interest of tetrazines in the surface functionalization of graphene.

Abstract
NIR Emitting Systems for Ex or In-Vivo Imaging
An ideal probe for biophotonics must fulfill many salient requirements, such as: high brightness in the biological transparency window, solubility in the physiological medium, non-toxicity, synthetic availability on relatively large scales, specificity and moderate cost.
The main goal of this presentation is to illustrate our different recent approaches in order to reach these objectives. Then, we will show the main constraints of biophotonic and will present two of our recent results : (1) molecular engineering on chromophores for optimised properties ,(2) development of methods of hydrosolubilisation and biocompatibility of these chromophores.

Abstract
Unconventional Applications of N-Heterocyclic Carbenes (NHCs) in Organic Materials Chemistry
Since their isolation in the late 1980's, the unique reactivity and properties of stable singlet carbenes – and in parti-cular N-heterocyclic carbenes (NHCs) – have led to their widespread applications as ligands for transition metals, and on their own as organocatalysts. Nevertheless, their applications in organic materials chemistry has so far been mostly limited to Pd-catalyzed cross-couplings, Ru-catalyzed alkene/yne metathesis (e.g. ROMP), and in the ring-opening polymerization of polar monomers (e.g. lactide).
In this talk, we present our recent efforts to expand the use of NHCs, and that of their main-group element adducts, as attractive building blocks in the design and synthesis of π-conjugated organic materials. Examples will include their use in fluorescence imaging probes for two-photon microscopy, and in the preparation of new push-pull chromophores.

Abstract
Quantum Dot-Based Organic-Inorganic Hybrid Materials for Optolectronic Applications
Our recent research involves the design, characterization and testing of devices constituting low bandgap conju-gated polymers, surface-engineered quantum dots (QDs), carbon nanotube (CNT)-QDs, QDs decorated nanowires, and QD coupled conjugated polymers. The resulting hybrid polymeric nanomaterials can be used for facilitating the charge/energy transfer and enhancing the charge carrier mobility in highly efficient optoelectronic and photonic devices. Exploiting the full potential of quantum dots in optoelectronic devices require efficient mechanisms for transfer of energy or electrons produced in the optically excited QDs. We propose semiconducting π-conjugated polymers as ligands to achieve energy or charge transfer. The hybridization of p-type π-conjugated polymers to the surface of n-type QDs can induce distinct luminescence and charge transport characteristics due to energy and/or charge transfer effects. QDs and π-conjugated molecule hybrids with controlled luminescent properties can be used for new active materials for light-emitting diodes and flexible displays. In addition, such hybrid systems with enhanced charge transfer efficiency can be used for nanoscale photovoltaic devices. We have also explored single nanoparticle based electronics using QDs and π-conjugated molecule hybrids with molecular-scale n–p or n-insula-ting (ins)–p-heterojunction structures.

Abstract
Strategies for the development of high energy density micro-supercapacitors
While demand for ever-smaller electronic devices has driven the miniaturization of a variety of technologies, energy-storage units have lagged in this regard. As power source size should be commensurate with the device it powers, significant efforts have been recently expended on integrating energy harvesting and storage micro-devices on-chip, with a view to building densely-integrated electronic systems with complete energy autonomy. Electrochemical capacitors - also known as supercapacitors - are reversible energy storage devices with high power density, rapid charge/discharge rates, and a long service life compared to batteries. These attributes come at the expense of a much lower energy density, a factor which has impeded the powering of a wireless node or any microelectronic device to date.
To bridge the gap in on-chip micro-supercapacitors, the PI’s team recently proposed a two-step method to manufacture a new, nano-architectured electrode assembly. The first step involves the formation of a current collector through Dynamic Hydrogen Bubble Templating (DHBT) electrodeposition. This leads to the formation of very large surface area films composed of a multitude of meso/macro pores, with strong adherence to the substrate. This structure provides a continuous pathway for the transport of electrons and enables the electrolyte to easily access all of the meso/macro pores. Next, pseudocapacitive materials are deposited onto the templated current collector to enhance the capacitance of the system. Our RuO2/3D-Au electrode exhibits the highest specific capacitance (3.5 F.cm-2) ever reported, with 96% retention after 2000 charge/discharge cycles and very low self-discharge rate (less than 9 mV/h). This is attributed to the unique properties of the interconnected 3D Au meso/macroporous template, resulting in a huge electrochemically-active surface area compared to the electrode footprint. These results will be presented in details.

Abstract
Designing nanostructures for enhancing photon harvest in photocatalysis and solar cells
I will present some of our most recent development in plasmonic and upconverting nanostructures and their applications in photocatalysis and solar cells. It illustrates the synthesis of novel, plasmonic Au nanoparticle decorated NaYF4:Yb3+, Er3+, Tm3+(denoted as NYF) – core @ porous-TiO2-shell microspheres, which can harvest solar photons over a wide spectral range from ultraviolet to NIR for efficient photocatalysis, significantly better than the benchmark Degussa P25. The enhanced activity is attributed to synergistic effects from nanocomponents arranged into the nanostructured archi-tecture in such a way that favours the efficient charge/energy transfer among nanocomponents and largely reduced charge recombination. The simple one-step synthesis of NYF in the presence of g-C3N4, which was not previously reported in the literature, leads to both high NYF yield and high coupling efficiency between NYF and g-C3N4. The Au-NYF/g-C3N4 structure exhibits excellent stability, wide photoresponse from the ultraviolet, to visible and NIR regions, and prominently enhanced photocatalytic activities compared with the plain g-C3N4 sample in the degradation of methyl orange. Very recently, by constructing a complete comparative framework, based on the similar catalysts having alloy synergistic effect or plasmonic effect, or both, we compared the plasmonic and synergistic effects. It helps answers an important, yet not previously addressed question: synergistic and plasmonic effects, which can make more important contribution to photocatalysis? On the other hand, quantum dots are also promising for photon harvesting because of their size-tunable bandgaps, even in the NIR range.

Abstract
Nanomaterials for Energy Conversion and Storage in Fuel Cells and Batteries, and Water treatment
PEM fuel cells are expected to play dominant role in future clean energy solutions for various applications. Develo-ping highly efficient low-Pt and Pt-free catalysts are the key solutions for the wide-spread commercialization of PEMFCs. We recently developed various novel Fe/N/C catalysts which exhibited higher activity in alkaline media and equivalent activity in acidic electrolyte compared to commercial Pt. Moreover, we systematically studied the decay mechanism of the MOF-based Fe/N/C catalyst, which is of significant important to improve the durability of Fe/N/C catalysts. On the other hand, through green chemistry and/or ALD techniques, we fabricated various novel Pt nanostructures, including nanowires, nanotubes, and single atoms. Compared to the conventional Pt nanopar-ticle/C commercial catalyst, these novel Pt nanostructures exhibited much enhanced activity (up to 10 times) and stability (up to 6 times) for fuel cells.
Both lithium-ion (LIB) and sodium-ion batteries (SIB) are promising technologies for energy storage. We developed a facile, inexpensive and scalable wet-chemical strategy to fabricate the Fe3O4/graphene composites and porous carbon spheres. The nanocomposite shows dramatically enhanced electrochemical properties including excellent reversible capacity, cyclability and rate performance in LIBs and SIBs. I will also talk about our research activities in water treatment.

Abstract
Synthesis of Micro-hydrogel Particles Consisting of Hyperbranched Polyamidoamines for the Capturing of Heavy Metal Ions and CO2
Polyamidoamine (PAMAM) dendrimers and hyperbranched polymers have attracted considerable interest in recent years. The highly branched structures together with a large number of functional groups in the main chains and end groups make these materials ideal for applications in host-guest encapsulation, nanoreactors, and delivery devices. In this study, we used both the advantages and limitations of the A2 + B4 polycondensation method for hyperbranched polymers to make micro-sized HPAMAM hydrogel particles through the dispersal of an aqueous HPAMAM solution obtained by A2 + B4 polycondensation into an immiscible liquid and then by carrying out the polycondensation until reaching the point of critical gelation. This simple method allowed us to make micro-sized hydrogel particles which wholly consisted of hyperbranched polyamidoamine without any additional crosslinking reagents. The crosslinked HPAMAM hydrogel particles were found to be highly effective for the capturing of heavy metal ions from an aqueous solution and CO2.

Abstract
Flexible Thermoelectric Generators Using Organic Materials by Printing Process
Thermoelectric energy conversion is an attractive and environmentally friendly way to recover energy from indus-trial waste heat or natural heat because of its potential for improving the energy efficiency. As thermoelectric materials, organic materials have unique advantages, such as cost effectiveness, low intrinsic thermal conductivity, high flexibility, and amenability to large area applications. Therefore, organic conducting polymers, which possess good electrical conductivity, have been actively researched. In addition, various carbon based materials such as CNT are also good candidates for organic thermoelectric materials. Herein, we will discuss a convenient method to fabricate flexible thermoelectric generators using various organic materials by printing process.

Abstract
Inkjet Printed organic transistors for medical applications
Due to its unique combination of both electronic and ionic/molecular conductivity in conducting and semicon-ducting organic polymers, these materials have emerged in recent decades as excellent tools to interface biology with conventional electronics, also identified as the topic of “the organic (or plastic) bioelectronics”. Ion-to-electron transducers operating directly in a biological media can be considered as the ideal device to “interface” with the biological world. This talk will show how the Organic ElectroChemical Transistor (OECT) can be considered as one of the building-block to operate such a transduction and thus play a new role in medical applications.
In parallel, such p-conjugated materials know increasing interests to emerge in printed electronics aplpications. Here, I will focus more particularly on one technology which was investigated this last decade; i.e the inkjet printing. The talk will present how such a technology allow the fabrication of several devices, as organic transistors with unique advantages.

Abstract
Self-assembled π-conjugated metallacages
The coordination-driven self-assembly strategy has allowed the access to a wide variety of molecular rings and cages. In some cases, the corresponding resulting host cavities exhibit guest inclusion properties, offering fascina-ting perspectives for various research topics. It is worth noting that only few of these structures are redox-active and most are electro-deficient. On this ground, we have been interested in constructing electronically comple-mentary electron-rich, π-conjugated, self-assembled rings/cages.1 The latter incorporate highly π-donating and S-rich frameworks and exhibit reversible redox characteristics and consecutive switchable behaviors. Our recent progresses on this field will be presented.

Abstract
High Efficiency Metal Halide Perovskite LEDs for Next-Generation Displays
Metal halide perovskites are emerging high color-purity emitters with low material cost. However, low electrolu-minescence (EL) efficiency at room temperature is a challenge that should be overcome. Here, we present efficient perovskite light-emitting diodes (PeLEDs) using various strategies to overcome the EL efficiency limitations where the perovskite layers are in forms of (1) 3D crystal structures, (2) quasi-2D crystal structures and (3) nanoparticles (NPs). First, to improve EL efficiency of PeLEDs based on 3D crystal structures, we introduced a self-organized buffer hole injection layer to reduce the hole injection barrier and block the exciton quenching at the interface. We found that the formation of metallic lead atoms causes strong exciton quenching, and it was prevented by finely increa-sing the molar proportion of MABr in MAPbBr3 solution. Second, quasi-2D perovskites were studied because of the advantages of quasi-2D perovskites such as the enhancement of film quality, exciton confinement and reduced trap density, and quasi-2D PeLEDs with high efficiency and brightness were demonstrated. Finally, perovskite NPs were studied because they can show high luminescence efficiency and high color-purity in both solution states and film states, and high efficiency PeLEDs based on MAPbBr3 and formaminidium lead bromide (FAPbBr3) NPs were also fabricated.

Abstract
Organophosphorus Polycyclic Aromatic Hydrocarbons: Synthesis, Electronic properties and WOLED
Polycyclic aromatic hydrocarbons (PAHs) are of great potential in molecular materials for opto-electronic devices. Molecular engineering of PAHs based on organic chemistry is of prime importance in order to build efficient devices. Indeed, PAHs’ band gap as well as supramolecular organization is tunable through modification of the p-system and lateral aliphatic substituents. An alternative approach uses the versatility of heterochemistry with the successful incorporation of N, O, S or B within the p-conjugated framework of PAHs. Here, we report that this appealing strategy can be extended to P-modified PAHs. A synthetic route to a family of P-modified PAHs is described. The reactivity of the P-center allows a straightforward HOMO-LUMO gap tuning as evidence by photophysical and electrochemical studies. The coordination ability of the P-center allows unprecedented coordination-driven assembly of PAHs onto transition metals. This molecular engineering strategy based on organophosphorus chemistry shows the potential of introducing P into planar p-extended frameworks.

Abstract
Synergistic impact of polymer backbone fluorination and alkyl side-chains on polymer: fullerene bulk heterojunction solar cells.
Many fluorinated conjugated polymers self-assemble into semi-crystalline thin films that include both parallel and perpendicular to the film substrate oriented lamellae. While this particular morphology improves charge transport and contributes to the exceptional performances of fluorinated polymer:fullerene solar cells, the underlying mechanism is still under debate. Fluorine substituents and long alkyl side chains are distinctive features of this class of polymers that influence strongly the thin film properties. Here, the impact of both features on the thin film morphology, charge carrier dynamics and photovoltaic performances are studied in detail. Polymers of identical conjugated backbones with differing number of fluorine atoms and side chains are investigated in both pristine thin films and polymer:fullerene blends. Grazing-incidence X-ray scattering and scanning transmission X-ray micros-copy measurements reveal that bulky side chains drive the crystalline lamellae into the mixed orientation, while the fluorine atoms enhance the face-to-face stacking cohesion and domain purity. Charge transport and photovoltaic measurements further show that the synergistic impact of both molecular features lead to high out-of-plane charge transport, low recombination rates and a more than 10% additive-free power conversion efficiency.

Abstract
Supramolecular assembly of polymeric dispersants with carbon based materials for the fabrication of fast-drying conductive inks
Printable electronics is touted as a paradigm shift for the electronics industry, as it provides an alternative to the complex and costly silicon-based technology. Recently, carbon nanotube based inks and graphene-based inks have emerged as a key player in the field because of their excellent conductivity, high transparency and their ability to be incorporated in a variety of devices. The commercialization of such inks requires control over manufacturing scale-up, low cost processing and access to defect-free graphene for optimal electrochemical properties.
We present here several inks compositions which are dispersed in aqueous or fast-drying organic solvents. For this purpose, the carbon material forms supramolecular assembly with various polymers. This technique is advanta-geous because it does not require covalent modification of the carbon backbone, it leads to highly conducting inks which are free of aggregates, even when concentrated.

Abstract
Plasma synthesis of bulk hybrid nanopowders
Ferrite spinels are magnetic ceramics with the general formulae MFe2O4, with M being one or several cations that can occupy either tetrahedral or octahedral sites, depending on their electronic structure and the temperature. This crystalline structure can usually accommodate oxygen vacancies by forcing the reduction or oxidation of some cations to ensure charge neutrality and results in some cations changing sites. This ability, combined to the magnetic properties of ferrites, allows them to be considered for a range of applications: catalysis, hyperthermia, magnetoca-lorimetry, environmental remediation, etc.
Typically, ferrite spinels are produced using soft chemical methods such as coprecipitation, sol gel synthesis and solvothermal methods. Once formed, it is necessary to anneal the product at high temperature to ensure the formation of a given phase. However, upon annealing, it is not possible to isolate metastable phases and the specific area decreases given that the nanostructure coarsens. Solution spray induction plasma (SSIP) have emerged as a method for producing bulk quantities of complex nanopowders that consists of decomposing a solution of precur-sors into a high temperature plasma reactor. Bulk quantities of metastable nanomaterials can thus be produced thanks to high quench rates and short residence times typical to SSIP without an annealing step. Using this versatile technique, we produced bulk quantities of high quality 30-100 nm diameter facetted ferrite spinels MFe2O4 (with M = Cr, Mn, Fe, Co, Ni, Cu and Zn and mixed metals spinels). We demonstrate that the M:Fe ratio can be easily tuned with the precursor ratio.

Abstract
Multi-scale Approach for the Design of Functional Materials
This presentation is an overview of the simulation tools available to assist experimentalists in designing functional materials. The gap between the structure of a molecule, the assembly of these molecules and the final functiona-lity of a material is significant and is often neglected. In fact, the link between the micro- and the macro-scales is far from being straightforward. To describe real systems, a series of models with a specific set of rules is required. Models must be chosen accurately to efficiently describe the system of interest. More specifically, each scale needs a certain level of approximation to address the specific problem. To ascertain accuracy of the representation, valida-tion with experiments is a crucial step. To illustrate this intimate link between experiments and simulation in the design of functional materials, several examples stemming from our lab are discussed. At the electronic level, a new polyelectrolyte membrane for fuel cell application is proposed. At the atomistic level, the tricky problem of glass transition of polymers is documented. Behavior of membranes upon shearing are discussed at the mesoscopic level. The actual arrangement of strands is explicitly discussed.

Abstract
New Polymers and Polymerization Methods for Plastic Electronics
Conjugated polymers have received a lot of attention since they combine the best features of metals or semiconduc-tors with those of synthetic polymers. On this basis, this class of materials can lead to printable and flexible photo-voltaic devices as well as other plastic electronic devices. Along these lines, we will describe novel synthetic methodologies for a simple and “green” preparation of such well-defined conjugated polymers. These new synthetic methods are based on direct (herero)arylation reactions that allow the formation of carbon-carbon bonds between heteroarenes and aryl halides. They do not require organometallic intermediates thereby significantly reducing synthetic steps, metallic by-products, and cost.

Abstract
Tuning graphene photonic properties by surface-confined supramolecular self-assembly
Graphene has potential photonic applications in optical modulators, photodetectors, light harvesting or emitting devices. However, its zero-bandgap electronic structure limits graphene role to transparent electrode. This is why graphene needs to be combined with a complementary photonic material to create a hybrid component with novel properties for advanced photonics.
In this context, the supramolecular self-assembly of organic building blocks on graphene is an original bottom-up approach towards novel materials displaying unusual properties. Hence, the possible fine-tuning of inter- constituents distances and orientations offered by the design of the building blocks makes the self-assembly approach very appealing for adjusting graphene photonic properties.
The experimental proof of concept shows the suitability of self-assembly techniques for the development of multi-functional hybrid dye/graphene 2D materials for nanophotonics, optoelectronics, light emitting or harvesting devices.

Abstract
3D-Molecular building blocks for surface Nanophotonics - the Nanoarchitectonics approach
From a chemical point of view, we have succeeded in mastering the elaboration of nanometric structures, leading to the development of molecular architectures which, on one hand, can perform various functions such as emission or absorption of light and on the other have the ability to self-assemble on a surface, thus forming a wide variety of molecular or nano-networks.
In this context, surface-confined supramolecular self-assembly has been the focus of extensive research in the past decade. Numerous strategies have been developed throughout to fashion ordered 2D arrays and have led to novel applications in molecular electronics, photonics and nano-mechanical devices. Nonetheless, whilst there are numerous examples of the use of supramolecular materials in current technology we are still at the early stages since the main difficulty encountered upon applying nanomaterials in functional technologies is that the functionalities and properties intrinsic to these materials are greatly limited by their inability to form ordered, integrated systems.
Herein we will discuss the importance of molecular design towards 3D-molecular building blocks that will, in turn possess the ability to form ordered surface-confined arrays with off−plane functionalities that will function as a whole integrated nanostructure. These integrated, functional surfaces will ultimately allow the “translation” of the molecular properties of the building blocks into the nanoscale opening the way towards a more “rational” approach for the development of nanomaterials.

Abstract
Chemical Synthesis and Self-assemblies of inorganic Nanomagnets.
Metallic nanoparticles and nanohybrids will initiate important development in nanotechnologies due to their specific chemical and physical properties (i.e. in catalysis, magnetism, optics, etc) and new development in sustainable energy (i.e. fuel cells). It is now well known that these properties are mainly controlled by the fine tuning of structural parameters such as the size, shape, crystallinity and composition. In order to study these specific properties, a wide variety of both chemical and physical routes have been developed for the synthesis. In particular, one of the specific challenges in the synthesis is to control and to characterize the nanohybrids at the nanometer scale. Concerning their fabrication, the chemical bottom up approach, is ideal to design this specific class of nanomaterials due to its versatility, facility and low cost. In the following, we review some of the most classical chemical routes to produce such nanohybrids focusing on the case on cobalt and Co-Pt nanomagnets. We discuss the concepts of nucleation, growth and self-organization for such objects and their consequence on their structural properties (size, shape, composition, ordering…).

Abstract
New approaches and materials for energy storage systems
The improvement of the performance and stability of energy storage systems such as rechargeable batteries and electrochemical capacitors require that new materials be developed. Our laboratory is currently involved in the chemical modification of active electrode materials for energy storage applications. Furthermore, we have also chemically modified non-electrochemically active components such as the binder and the carbon additive. More recently, superconcentrated electrolytes and electrochemical exfoliation of graphite have been also investigated. In this presentation, recent results from our laboratory will be presented and discussed. Technologies that have been recently protected will be also highlighted.

Abstract
2D Materials Based Electrodes for Label-Free Impedimetric Biosensing and Highly Efficient Hydrogen Evolution Electrocatalyst
The integration of graphene materials in biosensing platforms has gained great research interest in recent years. For using graphene as electrodes based material, bulk quantities are needed which are usually synthesized by oxidation of graphite to graphene oxide (GO) or by chemical vapour deposition route. For the present talk I will briefly overview our most recent work on CVD growth of graphene, graphene oxide (GO) synthesis, electrodes based graphene fabrication and aptamers developments for aptasensing applications. Indeed, the graphene@aptames combination could offer great potential to measure substances in clinical diagnostics, environmental analytics, food and biotechnology industries, process engineering and others. In parallel, I will present novel strategies to synthesize composites molybdenum diselenide (MoSe2) and used as a catalyst for hydrogen evolution reaction (HER).

Abstract
Application of Electrochemical Methods in Artificial Photosynthesis
Conversion of solar energy into transportable liquid fuels has been an important research theme in physical sciences for the last decade. Many artificial photosynthetic devices have been built with numerous iterations and enhan-cements, yet all fall short of the biological machinery. In the current presentation, two major problems in artificial photosynthesis will be discussed: 1) limited lifetime of the photo-absorber due to oxidative degradation and 2) deficient understanding of the complex oxygen evolution reaction (OER). In the first part of the presentation, a proof-of-concept photo-anodic device for OER will be demonstrated. Prolonged use of corrosion sensitive n-type silicon was made possible in water by application of an electrodeposited thin passivating layer of TiO2. A rare metal/insulation/semiconductor junction was employed for solution electrochemistry; insights into the tunneling electron transfer phenomenon involved in solution chemistry will be presented. In the second part of the talk, an investigation of the catalytic OER surface processes will be presented. By use of a redox titration experiment, the redox processes occurring at the surface of metal oxides during OER were investigated.

Abstract
Photothermal conjugated polymer bimorphs for soft actuators
Photothermal effect in conjugated polymers (CPs) have been collected strong interest in cell engineering and energy conversion into different type of energy such as electrical, mechanical, or chemical energy. Photothermally generated heat on a CP film under NIR exposure was applied for dissembly of protein structures to harvest live cell sheets without changing the original cell morphology at cultured state. In this presentation, photothermal actuation of a bimorph based on CP films will be presented. A thin conjugated polymer film was transferred onto a soft polymeric film to prepare a bimorph. Large deformation was observed from the bilayer with a bending angle larger than 90 deg, which allowed reversible formation of foldable structure by photothermal process. A model for rever-sible actuation was formulated through the thermal expansion of soft polymers, modulus difference between the layers, and temperature rise of CPs by NIR exposure. A Venus fly trap was achieved through photothermal folding, which could provide a new simple method to produce artificial hot trap and pocket. A wireless light driven switch could be demonstrated with the soft bimorph. As NIR can transmit not only trasnparent polymer but also various forms of organism and tissue, it should be beneficial for the generation of a bendable or imbedded electronics.

Abstract
Synthesis and applications of two dimensional transition metal dichalcogenides
Two dimensional (2D) transition metal dichalcogenides (TMDCs) have attracted great attention to complementing graphene such as zero band gap in recent few years. 2D TMDCs nanosheets have the potential to be used in various fields, such as nanoelectronics, optoelectronics, electrocatalyst, solar cells, photocatalyst and sensing platforms. Despite of their remarkable applicabilities, the studies on the synthesis of 2D TMDCs are still showing various limita-tion in layer controllability, large area uniformity. Thus, the focus of our research is to understand and control the growth of 2D TMDCs based on atomic layer deposition (ALD) and chemical vapor deposition (CVD). This talk will present the synthesis of various 2D TMDCs and its heterostructure. Furthermore, potential application of the synthe-sized 2D TMDCs, including PN diode, gas sensor, photodetector and electrocatalyst, will be introduced.

Abstract
Two-dimensional material-based electronics
Graphene has brought a great deal of excitement to nanoscience community with its attractive and unique proper-ties. Such excellent characteristics have triggered highly active researches on other two-dimensional (2D) materials, such as hexagonal boron nitride (hBN), molybdenum disulfide (MoS2), tungsten diselenide (WSe2) and so on. Especially, these emerging 2D semiconductors are promising candidates for flexible and transparent electronics. Furthermore, new physics observed in 2D semiconductors allow for development of new-concept devices by using their valleys, tunneling effect, photoluminescence, and optical responsivity. Recently, van der Waals heterostructures (vdWH) have been achieved by putting these 2D materials onto another, in the similar way to build Lego blocks. This enables us to investigate intrinsic physical properties of atomically-sharp heterostructure interfaces and fabricate high performance optoelectronic devices for advanced applications. In this talk, fundamental properties of various 2D materials will be introduced, including growth techniques for graphene and 2D semiconductors. Then, I will show high performance electronic/optoelectronic devices of vdWH, such as transistors, memories, and solar cells. Our works would pave a new way toward fabrication of future devices based on 2D materials.

Abstract
Self-assembled nanostructures for stimuli-interactive display
Development of stimuli-interactive display capable of spontaneously visualizing various external human sensible inputs has been of great interest and tremendous efforts are devoted to the visualization of nonvisible human senses. Field induced electroluminescence of either organic or inorganic fluorescent materials under alternating current (AC) has been extensively studied and its unique device architecture in which an emitting layer is separated with an insulator from electrode offers a new platform for designing and developing emerging stimuli-interactive displays. In this presentation, we demonstrate a pressure interactive AC display sensor that allows for both sensing and visualisation of pressure. Light emission upon exposure to an AC field between two electrodes is controlled by the capacitance change of the insulator arising from the pressure applied on top. Besides capacitive pressure sensing, our EL sensor allows for direct visualisation of the static and dynamic information of position, shape, and size of a pressurising object on a non-pixelated single device platform. The presentation also shows that simul-taneous sensing and visualization of the conductive substance is achieved when the conductive object is coupled with the light emissive material layer on our novel parallel-type AC-PEL device. A variety of conductive materials can be detected regardless of their work functions, and thus information written by a conductive pen is visualized, as is a human fingerprint with natural conductivity.

Abstract
Photoelectrochemical Water Splitting from Disordered Metal Oxide Semiconductors
The development of new types of energy generation devices is promoted by increasing public awareness that the Earth's oil reserves could run out during this century. As the energy needs of the planet are likely to double within the next 50 years, the stage is set for a major energy shortage, unless renewable energy can cover the substantial deficit left by fossil fuels. Photoelectrochemical (PEC) solar water splitting has become a central research theme for more than four decades, still, their efficiencies remain low. Despite extensive efforts devoted to modifying photoelectrodes through various bandgap and catalysis engineering, the efficient methodologies for charge transfer at electrode/electrolyte interface remain underdeveloped. In this seminar, I will introduce various unique methods to increase light harvesting efficiency to generate hydrogen from solar light by applying disordered engineering to metal oxide materials. Especially, high efficiency TiO2, WO3, and BiVO4 photoanodes with the modification and charge transfer across the electrode/electrolyte interface will be presented.
