The basicity of alkali metal methoxides in methanol. The effects of ion association on methoxide additions to activated anisoles [PDF]
, 1991 The formation of adducts with 1 :2 and 1:3 stoichiometry by methoxide addition to nitro-activated anisoles has been examined spectrophotometrically. For these equilibria the ‘basicity’ of sodium methoxide solutions in methanol is appreciably greater than

Advanced Materials, EarlyView.Density‐driven differential sedimentation fractionates solution‐assembled P3HT nanowires into crystalline and disordered constituents. High‐resolution cryo‐TEM directly visualizes the molecular chain packing within individual nanowires in real space, and recombining the fractions programs the mobility–stretchability trade‐off without chemical ...

Enhanced Xylene Sensing Performance of Fe‐Doped NiO Nanosheet Arrays via In Situ Growth
Advanced Materials Interfaces, EarlyView.Xylene is a hazardous volatile organic compound (VOC) widely present in industrial environments, and achieving sensitive and stable detection of xylene remains a significant challenge for gas sensors. Here, a one‐step hydrothermal route was employed to in situ grow p‐type Fe‐doped NiO nanosheet arrays on ceramic tubes for xylene detection.

Monolayer MoS2 With Ultrahigh Piezoelectricity: From ALD Dose Control to Device Performance
Advanced Science, EarlyView.This study demonstrates that controlling precursor dosages in atomic layer deposition (ALD) serves to regulate ultrathin oxide quality, which in turn determines sulfurization behavior and MoS2 monolayer continuity. The resulting continuous, low‐defect monolayers enable improved piezoelectric performance and support a flexible slippage sensor, linking ...

Zeitschrift für Naturforschung A, 1991 Fluorescence spectra of anisole at various concentrations and temperatures were measured. Using a standard, the molecular quantum efficiency was obtained. Ours and literature data were analysed to determine the rate parameters and other properties of the anisole excimer-monomer system.

Mechanisms of Temperature‐Dependent Hysteresis in Freestanding BaTiO3/MoS2 Heterostructures
Advanced Science, EarlyView.Freestanding ferroelectric BaTiO3 membranes are combined with monolayer MoS2 into 2D field‐effect transistors. At room temperature they provide ultrahigh‐κ gating with steep subthreshold swing and minimal hysteresis. Upon cooling, strong ferroelectric switching produces two stable memory states with long retention times.

Controlled Atom Transfer Radical Depolymerization
Advanced Science, EarlyView.Controlled atom transfer radical depolymerization allows for precise, uniform shortening of polymer chains to yield monomers on demand. By tuning catalyst concentration and temperature, this strategy prioritizes deactivation to maintain molecular weight control throughout depolymerization.

Phenonium‐Ion‐Mediated Skeletal Editing of Paracyclophanes
Angewandte Chemie International Edition, EarlyView.Phenonium‐ion chemistry enables the modular skeletal editing of paracyclophanes. Regioselective nucleophilic trapping expands one or both aliphatic bridges, enables iterative access to higher paracyclophane homologues, and translates bridge topology into a functional design parameter, as demonstrated with a bridge‐expanded TADF emitter.
