Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

THz-Raman Identification of labile products in the system "phenol-semiquinone-quinone" [PDF]
The paper presents the results of SERS studies of the dynamic behavior of "phenol-semiquinone-quinone" system. This system is a key part of chemiluminescent sensors for reactive oxygen species. The dynamics of the system seems to be very important in the processes that determine the secondary metabolism at the cellular level in molecular biology.

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

Simple phenol and phenolic compounds in food flavor
Simple phenol and phenolic compounds occur in a vast portion of our diet. This review attempts to discuss their occurrences relative to our food supply. In addition, their chemical, nutritional, and sensory properties are explored, as well as methods for their isolation, identification, and quantitation.

Shikimic Acid Pathway in Biosynthesis of Phenolic Compounds
Phenolic compounds are secondary metabolites found most abundantly in plants. These aromatic molecules have important roles, as pigments, antioxidants, signaling agents, the structural element lignan, and as a defense mechanism.

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.

Electrolyte Engineering Strategy with Catecholate Type Additive Enabled Ultradurable Zn Anode
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.

FTIR and GCMS analysis of epoxy resin decomposition products feeding the flame during UL 94 standard flammability test. Application to the understanding of the blowing-out effect in epoxy/polyhedral silsesquioxane formulations [PDF]
A novel method was developed for the sampling of volatiles produces by polymer decomposition during UL94 standard flammability tests, allowing to collect, separate and analyze the precise composition of the fuel mixture feeding the flame in the real flammability tests.
