A second polymorph of 3,4-bis(6-bromopyridin-3-yl)-1,2,5-thiadiazole
IUCrData, 2016 The title compound, C12H6Br2N4S, a second polymorph in the triclinic space group P-1, is presented. As in the earlier reported monoclinic polymorph in the space group C2/c [Becker et al. (2016). Chem. Eur. J. In the press], the thiadiazole ring is planar

High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells
Advanced Science, EarlyView.High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Resistant Peanut Genotype Reprograms Rhizosphere Metabolism to Enhance Bacterial Wilt Suppression
Advanced Science, EarlyView.The resistant peanut genotype selectively recruits beneficial bacteria, which coincides with the activation of salicylic acid (SA)‐dependent systemic acquired resistance (SAR) against Ralstonia solanacearum. Keystone rhizosphere metabolites are positively correlated with both beneficial microbiome assembly and SAR gene expression.

Angewandte Chemie, EarlyView.This work develops a spray‐assisted in situ assembly technique to construct AHF materials with nitrogen/oxygen‐regulated one‐dimensional channels on glass fiber, providing abundant active sites and enabling rapid transport for lithium ions. Subsequently, phosphate flame retardants are encapsulated via in situ polymerization, resulting in a thermally ...

Advanced Science, EarlyView.The electrolyte engineering of introducing tetrakis(4‐N, N‐dimethylaminophenyl)porphyrin (TDMAP) is designed to modulate Li+ solvation structure and solid electrolyte interphase, where the interaction with PF₆− anions is altered (Li+–NMe2–PF₆−). Consequently, the cells with optimal additive concentration achieve high Coulombic efficiency (∼99%), and ...

Angewandte Chemie, EarlyView.Thiophene is king! The fusion of thiophene rings to cycloalkynes super‐charged their copper‐free click chemistry applications, by (1) enhancing the alkyne reactivity (fastest cyclooctyne to date) and (2) rendering the alkyne fluorogenic (with fluorescence enhancement up to 150‐fold upon reaction), making these bioorthogonal reagents ideal for tracking ...
