Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors

open access: yesJournal of Applied Polymer Science, EarlyView.
A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.

In Situ Generation of a Robust Gel Polymer Electrolyte From a Poly(Ethylene Carbonate)‐Hydrogenated Nitrile Butadiene Rubber Containing Thermoplastic Vulcanizate Electrolyte

open access: yesJournal of Applied Polymer Science, EarlyView.
A gel polymer electrolyte thermoplastic vulcanizate (GPE–TPV) was prepared by blending HNBR and PEC by melt extrusion then thermally decomposing PEC to yield liquid EC. EC is absorbed into the crosslinked HNBR, yielding an electrolyte that is mechanically and electrochemically stable enough to permit cycling in a LiFePO4–Li half‐cell.

Effects of mixed microbial fermentation on the quality and metabolite profile of cassava leaf feed based on untargeted metabolomics

open access: yesJSFA reports, EarlyView.
Abstract Background Cassava leaves are a major byproduct of cassava processing and have a low utilization rate. In this study, Lactiplantibacillus plantarum, Saccharomyces cerevisiae, and Bacillus subtilis were used for solid‐state fermentation of cassava leaves to improve their feed quality. Results After 48 h of fermentation, the feed pH decreased to
