Thiol‐Modulation‐Induced Mesoporous Nanosheets with an Alloy/Intermetallic Heterophase for Efficient Electrochemical Ethylene Glycol‐Assisted Water Splitting

Advanced Functional Materials, EarlyView.
Sulfur‐capped mesoporous PtPbBi nanosheets (S‐PtPbBi MNSs) with an alloy/intermetallic compound heterophase and inhomogeneous tensile strain (≈3%) were synthesized by a thiol modification strategy, which exhibited excellent electrocatalytic performance for ethylene glycol oxidation reaction (EGOR).

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

Advanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction

Advanced Functional Materials, EarlyView.
Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Gas-liquid chromatography-mass spectrometry of synthetic ceramides containing phytosphingosine

Journal of Lipid Research, 1970
Ceramides containing phytosphingosine as base and one of the fatty acids 16:0, 18:0, 20:0, 22:0, 23:0, and 24:0, were prepared by direct coupling in the presence of a mixed carbodiimide. The ceramides were analyzed as the 1,3,4-tri-O-trimethylsilyl ether

Extracellular Matrix‐Mediated Crosslinking of Adhesive Hyaluronic Acid Patch for Treating Volumetric Muscle Injury

Advanced Healthcare Materials, EarlyView.
This study reports a novel strategy for preparing a biocompatible adhesive hydrogel crosslinked with a muscle tissue‐derived extracellular matrix (MEM) for in situ muscle regeneration. As a natural crosslinker, MEM not only mediates combinatorial polymer networks but also stimulates satellite cells to induce a cell‐free therapeutic solution.
