    Abstract: A method includes determining a plurality of molecular descriptors, each molecular descriptor of the plurality of molecular descriptors associated with at least one of an atomic scale property, a molecular scale property, and a compound-scale property. The method further includes selecting, by a selection operator and based on a minimization of an error, a subset of the plurality of molecular descriptors that affect a polymer surface energy, training a machine learning model to predict a polymer surface energy of a given polymer based on the subset of molecular descriptors and predicting, via the trained machine learning model, a surface energy of an input polymer.

    Abstract: A method of removing a fermentation inhibitor from an aqueous mixture of hydrolysis products from cellulosic biomass is disclosed. The method includes providing an aqueous mixture of hydrolysis products from cellulosic biomass, the hydrolysis products comprising at least one of pentose or hexose sugars and a fermentation inhibitor that inhibits a microorganism otherwise capable of fermenting pentose or hexose sugars; and at least partially extracting the fermentation inhibitor from the aqueous mixture with a first extractant by a first liquid-liquid extraction through a first porous membrane to provide a first extract and a raffinate, the first extractant having a water solubility of less than one percent by weight. In some embodiments, the aqueous mixture contains an insufficient amount of the microorganism to ferment the aqueous mixture. In some embodiments, the aqueous mixture is a fermentation broth. A membrane solvent extraction system for carrying out the method is also disclosed.
