Motivation: Faster Science, Better Science

Open Notebook Science Logos (Andy Lang, Shirley Wu)

Sharing: how much and when

There are NO FACTS, only measurements embedded

within assumptions

Open Notebook Science maintains the integrity of data provenance by

making assumptions explicit

Solubility Measurement Requests: DoSol sheet

•Outlier Bot: flags measurements with high standard deviation to mean ratios•Google Analytics queries – new solvent/solute searches•Solubility request form – researcher in Israel requesting pyrene in acetonitrile solubility for environmental soil contamination study•Application based models – high priority Ugi reactants

Solubility Prediction (Andy Lang’s Model)

Solubility prediction can generate requests for additional measurements

Solvent mixture and temperature: multidimensional solubility data

Actual Data (4-nitrobenzaldehyde)

From quadratic regression of 5D space

Feeds DoSol Sheet the next points to measure to best cover the space

Understanding in addition to empirical modeling

•Concentration (0.4, 0.2, 0.07 M)•Solvent (methanol, ethanol, acetonitrile, THF)•Excess of some reagents (1.2 eq.)
