1 Building a mobile reaction lab notebook Alex M. Clark, Ph.D. March Molecular Materials Informatics, Inc.!

2 !2 Electronic Lab Notebooks Many shapes & sizes: big, small, hosted, desktop, mobile Domains: chemistry, biology, instrumentation Many ELNs are generic: functionally equivalent to a Word document This talk is about chemical reactions

3 !3 Data Capture Reactions normally drawn for chemists rather than computers.

4 !3 Data Capture Reactions normally drawn for chemists rather than computers.

5 !4 Digitally Friendly

6 !4 Digitally Friendly primary! reactant catalyst intermediate secondary! reactants solvent byproducts reagent final! product

7 !5 Functionality Priorities: 1. computer-friendly datastructures 2. human-friendly workflow Because people are flexible! We can do better than the tired paper notebook metaphor balancing atom mapping green metrics quantity calculation sustainable feedstocks solvent lookup byproduct datasheets reaction transforms wizards

8 !6 Yield101 Prior art: designed originally for education Fancy reaction quantity calculator Simple & cheap All quantities mapped to structure: stoichiometry, molecular weight, mass, volume, density, concentration, moles, yield

9 !7 Green Lab Notebook Under construction as an ios app (phones & tablets) Superset of Yield101 core functionality General purpose reaction lab notebook, with supplementary green chemistry features Start with experiment drawing

10 !8 A New Experiment Start with a fresh slate: select the reactant placeholder Select the draw icon Sketch the reactant structure Apply the change: display shows reaction in progress Note molecular formula & molecular weight

11 !8 A New Experiment Start with a fresh slate: select the reactant placeholder Select the draw icon Sketch the reactant structure Apply the change: display shows reaction in progress Note molecular formula & molecular weight

12 !8 A New Experiment Start with a fresh slate: select the reactant placeholder Select the draw icon Sketch the reactant structure Apply the change: display shows reaction in progress Note molecular formula & molecular weight

13 !8 A New Experiment Start with a fresh slate: select the reactant placeholder Select the draw icon Sketch the reactant structure Apply the change: display shows reaction in progress Note molecular formula & molecular weight

14 !9 The First Step Draw product Draw stoichiometric reactants Draw reagents Balance

15 !9 The First Step Draw product Draw stoichiometric reactants Draw reagents Balance

16 !9 The First Step Draw product Draw stoichiometric reactants Draw reagents Balance

17 MOLECULAR MATERIALS INFORMATICS The First Step Draw product Draw stoichiometric reactants Draw reagents Balance!9

18 Quantities!10 Classify primary reactants & waste products

19 Quantities!10 Classify primary reactants & waste products

20 !11 The Second Step Append step Draw second product Balance: byproducts Stoichiometric reagent For step 2: any nonwaste product from step 1 is a primary reactant

21 !12 Quantities Fill in all available measurements All possible mappings autocalculated Cross-fertilised with stoichiometry & molarity Molecular weight really matters step 1 products reactants step 2 products reagents

22 !12 Quantities Fill in all available measurements All possible mappings autocalculated Cross-fertilised with stoichiometry & molarity Molecular weight really matters step 1 products reactants step 2 products reagents

23 !13 Green Metrics Process Mass Intensity (PMI) = mass of all reactants mass of products E-factor = mass of waste mass of products Atom Economy = Σ molecular weight products Σ molecular weight reactants Trivial calculations if the information is available.

24 !14 Green Metrics Totals for reactants, products & waste For each non-waste product: PMI, E-factor, Atom-E Always calculated, always recorded

25 !15 Green Solvents Environmental data from ACS GCI & GSK

26 !16 Feedstocks Reference collection: - info about supply chain - encourage renewable use sic Link lab-available quantities to experiment records Could synchronise with inventory software Lookup in vendor catalogs...

27 !17 Reaction Transforms Provide a pre-curated list of "green" reaction transforms Promote user entered experiments into transforms (numbering, clipping) Associate with: - reagents, catalysts & solvents - stoichiometry & quantities - yield & experimental conditions - literature & green reference data

28 !18 Further Work Work in progress: minimum viable product is close Experiment definition extensions to include preparation details, free text, spectra, references, pictures, etc. Synchronisation with centralised databases Automated structure lookup of problem-compounds: curation required Curation of sustainable feedstocks & green reaction transforms Facile promotion of experiment-to-transform: ultra convenient reuse

In other words, we are interested in what is happening to the y values as we get really large x values and as we get really small x values.

In other words, we are interested in what is happening to the y values as we get really large x values and as we get really small x values. Polynomial functions: End behavior Solutions NAME: In this lab, we are looking at the end behavior of polynomial graphs, i.e. what is happening to the y values at the (left and right) ends of the graph.
