MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

Advanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

Absence of static phase separation in the high-Tc cuprate $YBa_{2}Cu_{3}O_{6+y}$

, 2002
We use 89Y NMR in $YBa_{2}Cu_{3}O_{6+y}$ in order to evaluate with high sensitivity the distribution of hole content p in the CuO2 planes. For y=1 and y=0.6, this hole doping distribution is found narrow with a full width at half maximum smaller than ...

Temperature‐Enhanced Supramolecular Polymer Adhesion Provided by Concurrent Utilization of Calix[4]Pyrrole and Crown Ether Molecular Recognition

Advanced Functional Materials, EarlyView.
Simultaneous utilization of calix[4]pyrrole‐ and crown ether‐based molecular recognition allows the construction of a high molecular weight alternating supramolecular polymer. This heat processible polymer can be used as a durable and reusable adhesive on glass and steel with temperature‐enhanced adhesion strength without the need for a solvent ...

Asymmetric Nanofiber Membranes for Simultaneous Moisture Adsorption and Rapid Catalytic Hydrolysis of Nerve Agent Simulants in Atmospheric Environments

Advanced Functional Materials, EarlyView.
Asymmetric nanofiber membranes are constructed for simultaneous moisture adsorption and catalytic hydrolysis of dimethyl 4‐nitrophenyl phosphate (DMNP) in a wide range of relative humidity. The membrane exhibits high moisture adsorption capacity and fast hygroscopic rate.
