A Strong and Water‐Retaining Biomass Adhesive Inspired by Tofu

Advanced Functional Materials, EarlyView.
Drawing inspiration from the formation mechanism of the traditional food tofu, a strong and water‐retaining adhesive is designed using the soybean meal (SM) oxidized by glucose oxidase (GOx) and calcium sulfate oligomer (CSO). This design strategy effectively addresses the conflicting requirements of water‐resistant bonding strength and water retention

Phenol Deoxygenation over Hydrotreating Catalysts [PDF]

, 2014
Phenol deoxygenation has been investigated as a model reaction for the deoxygenation of fatty acid methyl esters in biodiesel. Hydrodeoxygenated biodiesel is a drop-in fuel for petroleum diesel, and is a premium diesel with a high cetane number.

A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

Advanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings

Advanced Functional Materials, EarlyView.
A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings
