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

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

Advanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Microbial degradation of phenol and phenolic derivatives

Engineering in Life Sciences, 2013
Phenol and its derivatives are one of the largest groups of environmental pollutants due to their presence in many industrial effluents and broad application as antibacterial and antifungal agents. A number of microbial species possess enzyme systems that are applicable for the decomposition of various aliphatic and aromatic toxic compounds.

Electrolyte Engineering Strategy with Catecholate Type Additive Enabled Ultradurable Zn Anode

Advanced Functional Materials, EarlyView.
A catecholate‐type molecule is proposed as a multifunctional electrolyte additive, providing a strong buffering ability as well as homogeneous (101)‐textured electroplating morphology. The modified Zn anode exhibits a remarkable rate capability, extraordinary reversibility, and superior cyclic stability.

Native Lignin Migration and Clustering in Wood: Superhydrophobic, Antimold, and Tribonegative Layers for Rain‐Driven Electrification

Advanced Functional Materials, EarlyView.
This study proposes a sustainable solution for rainwater‐driven energy harvesting by harnessing the intrinsic properties of lignin in wood. The first demonstration of an all‐wood tribonegative material for liquid–solid triboelectric nanogenerators is presented, eliminating the need for fluorine‐containing polymers and functional additives. Abstract The
