Abstract: A non-contact material assessment system and method are provided. In embodiments, a system includes: a radiation source generating a pattern of diffracted elements; a detector configured to: capture a first image of a first diffracted element when a sample is in an initial state, and a second image when the sample is in a second state; and capture a first image of a second diffracted element when the sample is in the initial state, and a second image when the sample is in the second state; and a controller to: determine a displacement of the first diffracted element based on the first and second images of the first diffracted element; determine a displacement of the second diffracted element based on the first and second images of the second diffracted element; and determine a characteristic of the sample over based on the displacement of the first and second diffracted elements.

Abstract: Disclosed herein is a compound made by copolymerizing a poly(ethylene glycol) acrylate with a first acrylate monomer having a first functional group that interacts with a third functional group having a third functional group type selected from anionic groups, cationic groups, or perfluoroalkyl groups. Optionally, the copolymerization includes a second acrylate monomer having a second functional group that interacts with a fourth functional group having a fourth functional group type selected from anionic groups, cationic groups, and perfluoroalkyl groups. The third functional group type and the fourth functional group type are different. When the compound is porous, as when made by high internal phase emulsion polymerization, it may be used for per- and poly-fluoro alkyl substance decontamination.

Abstract: A method that includes receiving user input associated with identifying a threshold point associated with a classification task, identifying, a machine learning model, in the first set of visual data, a machine placement candidate point associated with identifying the threshold point, and identifying, based on the machine placement candidate point, a set of baseline confidence values via a baseline uncertainty model. The method includes training the machine learning model based on a determined state space by identifying, subsequent sets of visual data additional threshold points, receiving user feedback indicating an accuracy, comparing the baseline confidence values with locations associated with the additional threshold points, generating reward values based on an identified amount of error, and configuring the machine learning model based on the reward values. The method includes identifying in a second set of visual data, via the trained machine learning model, a visual feature associated with the classification task.

Abstract: Described herein is a chemoenzymatic route to produce the small molecule sebacic acid from the renewable feedstock, e.g. vegetable oil. In one embodiment, this involves treating the a starting material such vegetable oil with KMnO4, sodium thiocyanate, and acid to obtain sebacic acid. Yield could be improved by pretreating the starting material with a lipase and then with a linoleic acid isomerase obtained from Propionibacterium acnes to obtain trans-10, cis-12 conjugated linoleic acid (CLA). The sebacic acid can be further processed with lipase and 1-butanol to obtain dibutyl sebacate.
