visi torsvisi tors
A F M C a n t i l e v e r s U p d a t eIn a recent issue of the PFPC Bulletin (January – June 2003), we reported on the discovery
by PFPC Executive Member Associate Professor John Sader that V-shaped cantilevers used
in the Atomic Force Microscope do not offer the advantages they are purported to have.
Instead of minimising the effects of torsion, a property that has underpinned their usage,
V-shaped cantilevers actually increase twist. In that issue, the following question was asked:
Do we need V-shaped cantilevers at all? In this issue, we report on the impact of this finding in
the short timeline since its announcement in 2003.
At the heart of the AFM lies a force-sensing cantilever. Typically between 100 and 200 microns
long, the AFM cantilever is scanned across a surface to generate a topographic image or
measure surface properties. The first cantilever design (1986) incorporated a simple rectangular
geometry, closely resembling a diving board. Soon after, the more complex V-shaped geometry
was introduced (1987) with the explicit intent of minimising the effects of lateral forces,
which can be detrimental to performance. This has led to current day industry standards,
which utilise a combination of rectangular and V-shaped cantilevers, depending on the
application. Importantly, V-shaped cantilevers have been used widely in applications where the
effects of torsion are to be minimised, such as and force measurements, including colloid probe
measurements.
Intuitively, it seems entirely reasonable that V-shaped cantilevers must provide higher
resistance to twisting in comparison to rectangular cantilevers, with the skewed arms of the
V-shape providing the extra support. John’s research proves that such intuitive analysis leads
to the wrong conclusion, with the V-shaped geometry providing less support. This finding is
expected to impact significantly on manufacturing standards and usage by enabling the
universal use of rectangular cantilevers in AFM applications. In turn, this would facilitate
accurate cantilever calibration
and measurement interpretation,
thus improving the performance
of the instrument.

These findings by John Sader have led to global attention and publicity in the international scientific media, including a report in the key general
science magazine Scientific American. Leading AFM manufacturers have responded to this finding, by modifying their product lines. Significantly,
one of the world’s largest manufacturers, Veeco, USA, has now replaced their widely used silicon V-shaped cantilevers with a new series of
rectangular cantilevers. In their product flyer features the headline of “a rectangular cantilever to minimize lateral forces”, the discovery that
John reported less than 18 months ago. They also state that the new cantilevers offer superior performance in “nearly every facet of operation”,
supporting John’s recommendations.
Given the short timeline since announcement of the discovery, its appearance on the international market is truly significant. With the key operating
principle of the V-shaped cantilever removed, and leading manufacturers moving towards rectangular designs, the stage is now set for the global
usage of rectangular cantilever in AFM applications.
Professor David Boger announced over 18 months ago that he
would retire at the end of 2004 and in doing so step down as
Director of the PFPC. It was at this time that Professor Tom Healy
also announced he would step aside as Deputy Director. Given that
this was decided at the start of 2003 there has been ample time for
succession planning by the Centre’s Executive and Advisory Board
and smooth implementation of this succession plan. As a result of
these changes to the Directorship the Australian Research Council
(ARC) conducted an adhoc review of the Centre in November. Soon
after this review the ARC advised The University of Melbourne that
they had approved the appointment of Professor Geoff Stevens as
Director of the PFPC. Professor Franz Grieser will join Professor Derek
Chan as the Deputy Directors of the Centre from 2005.
Geoff along with Derek and Franz have been involved in this unique
colloidal and interfacial science and technology group here at
The University of Melbourne since the conception of the PFPC’s
predecessor (the AMPC) in the early 1990’s. The passing of the baton
from the first generation of this group (Healy, Boger and White) to
the second generation (Stevens, Chan and Grieser) is now complete.
Geoff, a Professor of Chemical Engineering, has an excellent record in
research leadership and management. His expertise is in interfacial
phenomena associated with the transfer of molecules across
interfaces, particularly separation processes, such as solvent
extraction and ion exchange as well as emulsion stability. Geoff has
been playing a key role in both the Liquid-Liquid Systems and Solid-
Liquid Systems research programs of the PFPC.
David and Tom have been integral members of the Centre and both will
remain actively involved in the PFPC in their semi-retirement. David
will take on the role as Chair of the Advisory Board and Tom as Chair
of the new Scientific Advisory Committee to be formed in 2005.

Members of the PFPC will receive over $6 million in new Australian
Research Council (ARC) funding following the announcement of the
results from the 2004 funding round.
Fifteen new grants have been awarded to members of the PFPC
including nine ARC Discovery grants, three ARC Linkage–Infrastructure
Equipment & Facilities (LIEF) grants and two ARC Linkage Project
grants along with one National Health and Medical Research Council
(NHMRC) Project grant. Many of the new grants involve the Centre’s
research and industry collaborators within Australia and overseas.
Included in this new funding is a LIEF grant totalling $932,870 which
will enable the purchase of state of the art equipment for a Materials
and Surface Characterisation Facility. PFPC members involved in this
grant include Professor Frank Caruso, A/Professor Dave Dunstan,
A/Professor Paul Mulvaney, Professor Jannie van Deventer, Dr Grant
Lukey, and Professor Geoff Stevens along with the Centre’s new
Federation Fellow Professor William Ducker. The multi-user facility
will provide PFPC researchers and other research groups across
the University of Melbourne, Monash University, RMIT University
and CSIRO with a suite of analytical instruments essential in the
development of advanced materials.
Two ARC Discovery project grants in the nanomaterials area were
also awarded. A/Professors Paul Mulvaney and John Sader in
collaboration with Professor Luis Liz-Marzán (Univ. of Vigo, Spain),
Dr Greg Hartland (Univ. of Notre Dame, USA) and Dr Michael Giersig
(CAESAR, Germany) will receive $1 million over 5 years for an ARC
Discovery project that will explore how ultrasmall mechanical devices
made from molecules and small crystals work. Federation Fellow
Professor Frank Caruso and Dr John Quinn along with collaborator
Professor Tom Davis (Univ. of NSW) were also awarded a 5 year grant
totalling $1.3 million that will use advanced polymer chemistry to
develop “smart” polymers that can controllably respond to changes in
their surroundings. These “smart nanomaterials” are expected to find
application in the agricultural and pharmaceutical sectors. This grant
includes an Australian Postdoctoral Fellowship awarded to PFPC
researcher John Quinn.
Professor Peter Scales was successful with two ARC Linkage
project grant applications. Peter in collaboration with fellow PFPC
ARC and NHMRC Grant Funding Success member Dr Ross de Kretser and industry partner Rio Tinto will receive
$240,000 over 3 years from the ARC for a project that aims to provide
a quantitative basis for selection, design, operation and maintenance
of filter devices. The findings from this project are expected to
reduce the incidence of poor operational outcomes for filter presses
and provide a sound basis for the maintenance of filter cloths and
membranes used by the minerals industry. Peter in collaboration with
PFPC Industrial Fellow Dr David Dixon and industry partner Fonterra
Cooperative Group Limited was also awarded a 3 year grant totaling
$288,882 which will aid in determining the best choice of dewatering

The July – December period was a busy time for PFPC members with
a number of them playing major roles in conferences around the
Asia-Pacific region.
During the week of 23 August the XIVth International Congress on
Rheology was held in Seoul, Korea. More than 650 people from all
over the world attended the Congress, organised by the Korean
Society of Rheology. Professor David Boger was the Opening Plenary
Speaker at the Congress, where he delivered a lecture “From macro
to microscopic flows”. Professor Peter Scales presented an Invited
Keynote Lecture “The compression rheology of suspensions”, while
students Lucy Rodd and Joeska Husny also presented papers. The
PFPC has a very close friendship with the Korean rheology community.
Peter is now President of the Australian Society of Rheology and
this year represented the Asia-Pacific region on the International
Committee on Rheology. Australia and Korea publish a joint journal,
The Korea-Australia Rheology Journal. David will take on the role of
Australian Editor of this journal in his retirement.
Key PFPC Participation at Asia-Pacific Conferences
From left to right are: Professor Jae Hyun, Korea University, who
was the conference organiser of the XIVth International Congress on
Rheology; Professor Manfred Wagner, Berlin Technical University, who
is the new International Secretary of the International Committee on
Rheology; Professor Ki-Jun Lee, Emeritus President of Seoul National
University, eminent chemical engineer and rheologist who has played
a major role in bringing the chemical engineering communities in
Korea and Australia closer; and on the right is Professor David Boger.
Dunstan, who is a member of the PFPC. Professor David Boger
opened the conference with a Plenary Lecture, entitled “Exploiting the
rheology of hydrocolloids”. Professor Frank Caruso also presented a
Plenary Lecture entitled “Nanoengineered colloid-based materials
for controlled delivery” and PhD Student Alex Lubansky, presented
a paper at the Conference. A range of topics were covered during
the conference including molecular structure and interactions, novel
characterisation methods, rheology, hydrocolloids in emulsions/
surface chemistry, and applications to food, dairy, medical and the
pharmaceutical industries.
During September the 2004 Australia-Japan Symposium was held
as part of the 57th Divisional Meeting on Colloid and Interface
Chemistry of the Chemical Society of Japan. The Divisional Meeting
had 650 registrants and 7 parallel sessions with some 400 papers
and 188 posters. It was pleasing to see that the Australia-Japan
session covered as much as any other session of the Divisional
Meeting over the 3 days. It is a clear indication of the overwhelming
success of the Australia-Japan Symposium. Professor Tom Healy
along with Professor Neil Furlong, Professor Toyoki Kunitake and
Professor Yoshio Okahata were the key instigators behind the first
Australia-Japan Colloid Conference, held in Fukuoka, Japan in 1992.
The Australia-Japan Symposium has helped to establish extensive
collaborative research efforts between Australia and Japan. The
PFPC was represented at this most recent meeting, by Professor Tom
Healy, Professor Franz Grieser, Professor Geoff Stevens, Professor
Derek Chan and Dr Benno Radt, who all presented valued papers.
This followed in early October with the 6th Engineering Conference
International Meeting on Separations Technology, at Fraser Island,
Queensland, Australia. The conference focussed on the engineering
challenges of capture and reduction of greenhouse-gas emissions,
supply of economic and safe urban water and the development of low
environmental footprint minerals extraction processes. Conference
attendees came from around the globe including Europe, USA, Japan,
China as well as Australia. Incoming PFPC Director Professor Geoff
Stevens was a member of the International Organizing Committee.
Geoff along with fellow PFPC members Professor Peter Scales and
PhD students Kelly Yung and Julianna Franco represented the Centre
at this Meeting.
The PFPC is proud to have played a major role in these conferences.
Immediately after the Korean congress, during the week of 30 August,
members of the PFPC attended the 7th International Hydrocolloids
Conference, in Melbourne organised by Associate Professor Dave

(Associate Investigator) along with fellow collaborator Professor
Michael Hill from the University of NSW. This 3 year grant (totaling
$409,750) will be administered by the University of NSW and is entitled
“Adaptive Behaviour of the Arteriolar Wall”.
I commenced postgraduate studies at the University of Melbourne in 2000, under the supervision of Professor Geoff Stevens. This research focussed on the development of site remediation technologies for cold regions, resulting in the design, construction and commissioning of a mobile water treatment system specifically for use at remote cold-regions contaminated sites. The water treatment system was used to treat waters from a former waste disposal site near Casey Station in Antarctica, during removal of wastes and contaminated sediments, to prevent dispersal of contaminants into the nearby marine environment. The water treatment technologies and methods developed for the site clean-up project in Antarctica have been shown to be effective for prevention of contaminant dispersal.
The Antarctic project that I was involved in as a PFPC student is a perfect example of the benefit of cross-discipline expertise available within the PFPC. In order to
PFPC Graduate Profile
design and optimise the water treatment system, I collaborated with a number of chemists and engineers, as well as utilised many of the new analytical techniques and mathematical theories developed by members of the PFPC.
Since graduating from the PFPC in April 2004 I have commenced a 12 month research fellowship from the Japan Society for the Promotion of Science. Working as a guest researcher in the Environmental Engineering Department at the Kanazawa Institute of Technology in Japan I am researching the removal of dissolved metal contamination from waters using novel ion-exchangers/adsorbents. The PFPC and Kanazawa Institute of Technology have been involved in a collaborative research effort in metal ion extraction since 2002 and I look forward to contributing to this collaboration and continuing my association with the PFPC.

Coinciding with the PFPC’s Advisory Board Meeting the
Particulate Fluids Processing Centre held a half day Symposium
on Tuesday 9 November. The Symposium provided PFPC students
and staff with the opportunity to hear from an impressive line up
of internationally distinguished scientists and engineers. PFPC
Advisory Board Members Professor Brig Moudgil, Dr Richard
Buscall and Professor Graeme Jameson participated in the
symposium along with the PFPC’s Professor David Boger and
Professor Tom Healy.
The Symposium opened with a presentation by Professor Brij
Moudgil, Director of the Particle Engineering Research Centre at
the University of Florida, USA entitled “Nanoengineered particulate
based systems for enhanced performance in microelectronics,
pharmaceutics and process industries”. Brij is Director of a
Centre funded by the National Science Foundation in the USA,
a funding scheme for research centres that is analogous to
the ARC’s funding scheme for Special Research Centres.
Dr Richard Buscall, from the ICI Strategic Technology Group,
UK followed with a very entertaining talk on “Growth of
colloidal particles and microphases by controlled precipitation”.
Richard has had a long association with the Centre and took
the opportunity to revisit some of the research that he and
PFPC member Professor Peter Scales collaborated on in the
late 1980’s.
Introduced by Professor David Boger as “one of Australia’s
living treasures” Professor Graeme Jameson, inventor of the
Australian Jameson cell, gave a presentation on “Bubbles,
drops and particles” highlighting several of the research
projects that are being undertaken in the ARC Special Research
Centre for Multiphase Processes in Newcastle, NSW of
which he is Director. Graeme’s visit led to fruitful discussions
with PFPC researchers and it is hoped that a new collaborative
research project between the two centres will be established in
the not too distant future.
Professor Tom Healy talked on one of his favourite research topics
(“The electrical double layer at non-polar solid and liquid-aqueous
interfaces”) which highlighted an area of research that he has
been re-examining of late which he first began with Professor
Doug Fuerstenau, of the University of California, Berkeley in
the 1960’s. The symposium concluded with Professor Boger
discussing some very exciting observations in the field of
microfluidics in a presentation titled “From macroscopic to
microscopic flows: something old, something new, and something
very new”.
We were delighted that Professor Jae Chun Hyun, who is Director
of the Applied Rheology Center (ARC) at Korea University, in Seoul
also had the opportunity to present an overview of his Centre and
research during his visit.
We thank our Board Members for participating in the Symposium
and for providing staff and students with the opportunity to hear
about their exciting research programs.

As the Shell Graduate fellow, I completed
my PhD in Chemical Engineering in 2002
from Carnegie Mellon University, USA
on colloidal force measurements using
atomic force microscopy (AFM) and total
internal reflection microscopy. I came
to the PFPC for a two year international
postdoctoral research fellowship funded by
the National Science Foundation to study
the interactions between emulsion droplets
using AFM. These fellowships are designed
to encourage US researchers to make
research connections and gain experience
outside the US.
I was initially attracted to the PFPC as a host
institution for my fellowship based on the
centre’s world renowned reputation for high
quality research in colloids and the diversity
in research background of the people in the
PFPC. The other significant aspect to me
was that the PFPC provided the opportunity
to learn about new areas and expand my
research directions because of the diversity
of the people and research at the centre.
I have found the last two years to be the
most exciting and engaging of my research
career. In collaboration with researchers
across the PFPC we have made some
exciting discoveries in examining both the
behavior of surface forces between oil
droplets and the hydrodynamic drainage
between droplets on a length scale never
before examined by using AFM. I have
also had the opportunity to work in other
PFPC research areas including froth
flotation, diatom adhesion to surfaces, and
studying the dynamic forces and stability in
nanoparticle synthesis.
In September I was appointed as a senior
lecturer in the Department of Chemical
and Biomolecular Engineering, here at the
University of Melbourne. I plan to establish
a research program in the area of the
interaction forces in “soft colloids” and
complex fluids and apply this expertise to
problems relevant to living systems on the
cellular level. I look forward to continuing to
be a part of the PFPC.

PFPC Staff Member ProfilesPFPC Staff Member Profiles
After finishing a 5 year University degree
majoring in Chemistry at the University of
Neuchatel, I worked for 6 months at Novartis,
a pharmaceutical company based in Wallis,
in the south of Switzerland. I then started
my PhD also at the University of Neuchatel,
with Professor Helen Stoeckli-Evans in
collaboration with Professor David Fenton,
at the University of Sheffield, England.
My PhD thesis focussed on the synthesis
and characterization of tetra-substituted
pyrazine based organic ligands and their
bi-complexation with metallic ions, which
have great potential as magnetic materials.
In 2003, I received a 1 year postdoctoral
fellowship from the Swiss National
Science Foundation to do research in the
PFPC’s Nanoparticle Lab led by Associate
Professor Paul Mulvaney. His research
is quite diverse and I was very interested
in combining research with both the AFM
and nanoparticles. My main project here
in the PFPC is based on fabricating 2D
and 3D arrays of CdSe@ZnS quantum dots
(QDs) and studying their properties using
confocal microscopy, AFM and near-
field scanning optical microscopy. Such
systems show potential for a large range
of applications, including photonic crystals
used in waveguides or information storage.
I am also interested in working in the general
area of atomic force microscopy (AFM)
particularly imaging and characterization
of cantilevers. I have found my time here at
the PFPC very interesting so much so that
I decided to apply for a 6 month extension
to my fellowship which I am happy to say
was successful.
Collaboration is I think the main key in
science and research. The PFPC seminar
program run every fortnight is a good
opportunity to share information and ideas
between researchers. I have to admit that
one of the funniest moments, since arriving
in Australia occurred when I first attended a
PFPC seminar - I was listening to a speaker
wearing a T-shirt, shorts and thongs…this is
very Australian I think… Switzerland is far
too cold for this and the general strictness
of Swiss people might not have allowed it.
I definitely appreciate the relaxed way of
presenting seminars in Australia!

(22-27 August)
Steve Carnie was a member of the
Organizing Committee for CTAC2004,
Melbourne, Victoria 2004 held from
27 September to 1 October
Ray Dagastine travelled to the UK
in September to attend the Faraday
Discussion a129: Structure and Dynamics
at Liquid-Liquid Interfaces, at the University
of Cambridge, Cambridge, followed by
the EURESCO Conference: Interfaces and
Colloidal Systems, in Giens, France. During
the visit to England Ray met with Professor
Paul Luckham at Imperial College, London,
UK to discuss experimental methods.
A number of students who undertake their postgraduate degrees with the PFPC have the
opportunity to conduct part of their project in a leading international laboratory. Although
these visits are typically 2-3 months some students conduct more extensive studies with our
international research collaborators. PFPC student John Provis has recently commenced an
extended visit to a key university in the USA.
I am currently spending 12 months working in the Department of Materials Science and
Engineering, University of Illinois at Urbana-Champaign, USA, continuing my PhD project on
mathematical modelling of the structure and synthesis mechanism of amorphous aluminosilicate
geopolymers. I am working here with Professor Trudy Kriven, an Australian who has been in the
USA for over 20 years. Trudy is collaborating with PFPC researchers on several geopolymer-
related projects. My research here is funded by an Australian-American Fulbright Postgraduate
Scholarship, the PFPC and The University of Melbourne.
The change of research focus from Chemical Engineering to Materials Science has been a
very interesting experience for me, with the language divide between the two fields almost as
challenging to overcome as the change from speaking Australian to trying to speak American!
The life of an American PhD student is very different to that of an Australian student, with the
first few years of the program focussed mainly on coursework. I’m not actually taking any of
these courses, but I have been able to sit in on some lectures and seminars which have given me
a look at a completely different style of postgraduate program to anything I’ve seen in Australia.
My time here in the USA is providing me with an amazing array of opportunities, both research-
related and otherwise.
