Label‐Free SERS Fingerprinting of Neuroprotein Conformational Dynamics in Human Saliva

Advanced Materials, EarlyView.
Galvanic molecular entrapment (GME) is a label‐free method for detecting and quantifying neuroprotein conformational states. This technique enables direct surface binding and in situ hotspot generation around molecules, effectively overcoming challenges related to target localization and mismatched hotspot geometries.

Inter‐Atomic Synergy on Single‐Atom Alloy Promotes Cyclohexanone Oxime Electrosynthesis

Advanced Materials, EarlyView.
Electrosynthesis of cyclohexanone oxime using renewable electricity offers a greener alternative to traditional energy‐intensive methods. Here, we develop a Fe1Bi single‐atom alloy that delivers 70.9% Faradaic efficiency and 0.94 mmol cm−2 h−1 yield rate through the atomic‐scale synergistic mechanism.

Nitroxide‐Mediated Photo‐Polymerization: A Swiss Army Knife for Microfluidic Design

Advanced Materials Technologies, EarlyView.
This article illustrates the application of NMP2 to the rapid (less than 1 h) photostructuring and sealing of model structures intended for microfluidic applications. Remarkably, the careful design of resin composition allows completing these steps by simply spreading bare monomer (i.e., no added photoinitiator) on top of the bottom layer embedding ...

Cancer Cell‐Intrinsic Cholesterol Induces Lipid‐Associated Macrophage Differentiation via SP1 Palmitoylation to Promote Prostate Cancer Progression

Advanced Science, EarlyView.
Cancer cell‐intrinsic cholesterol promotes the S‐palmitoylation of SP1, increasing its nuclear translocation and driving the transcription and secretion of MDK, which in turn facilitates the differentiation of macrophages into a lipid‐associated phenotype.

Crown-hydroxylamines are pH-dependent chelating N,O-ligands with a potential for aerobic oxidation catalysis

Nature Communications, 2023
Despite the rich coordination chemistry, hydroxylamines are rarely used as ligands for transition metal coordination compounds. This is partially because of the instability of these complexes that undergo decomposition, disproportionation and oxidation ...

The Alkali-Tolerant Bacterium of Bacillus thuringiensis EM-A1 Can Effectively Perform Heterotrophic Nitrification and Aerobic Denitrification

Frontiers in Environmental Science, 2022
Removal of nitrogen from hydroxylamine could effectively improve the wastewater treatment efficiency. In this work, Bacillus thuringiensis EM-A1 was obtained from a biogas digester with hydroxylamine as the only nitrogen source.

Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.
