Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses
Advanced Science, EarlyView.ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Toward an anisotropic atom-atom model for the crystalline phases of the molecular S8 compound
, 2001 We analize two anisotropic atom-atom models used to describe the crystalline alpha,beta and gamma phases of S8 crystals, the most stable compound of elemental sulfur in solid phases, at ambient pressure and ...

Advanced Science, EarlyView.Photocatalytic treatment of glyphosate herbicide in agricultural wastewater is achieved through the cooperative effect of the local polarization field and dipole field mediated by lattice‐distorted carbon nitride. Glyphosate is completely degraded via selective C─P bond cleavage with a CO evolution rate of 1166 µmol g−1 h−1.

Advanced Science, EarlyView.We present a mechanochemical, radical‐mediated hydroselenation of alkenes under ambient conditions. This method modularly generates alkyl selenyl radicals from elemental selenium and alkyl (pseudo)halides, utilizing PhSiH3 and H2O as hydrogen atom donors, with the water likely originating from the air and/or trace water present in the reagents ...

Advanced Science, EarlyView.We demonstrate the fabrication of a series of reduced‐GO nanofiltration membranes containing intercalated polyaromatic conjugated molecules of different structural classes. These tuned‐nanochannel membranes perform “deep nanofiltration” with remarkably high monovalent salt rejections and near‐total divalent salt rejections in a large concentration ...

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery
Advanced Science, EarlyView.We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent

MetalCenter‐Dependent Selectivity Divergence in MN4 Single‐Atom Catalysts for Aerobic HMF Oxidation
Advanced Science, EarlyView.Two single‐atom catalysts with M‐N4 configurations (FeN4 and CoN4) were developed for selective HMF oxidation. FeN4 achieves 93.9% selectivity toward FFCA via superoxide anions (O2•−), while CoN4 preferentially produces FDCA through hydroxyl radicals (•OH). DFT calculations reveal that distinct adsorption energies and charge redistribution at the metal
