Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

Advanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Controlled Formation and Unusual Reactivity of Cyanohexatriyne (HC₇N), a Synthetically Challenging Interstellar Cyanopolyyne. [PDF]

Chemistry
First controlled formation of cyanohexatriyne (HC7N) is achieved using a cobalt–alkyne masking strategy that overcomes the intrinsic instability of nitrile‐substituted polyynes. The approach enables spectroscopic validation of HC7N and reveals its pronounced electrophilicity through a selective conjugate addition with diethylamine.

Lignin-containing Feedstock Hydrogenolysis for Biofuel Component Production

Bulletin of Chemical Reaction Engineering & Catalysis, 2018
In this paper, the commercial 5%Pd/C and 5%Pt/C catalysts and synthesized 5%Pt/MN-270 and 5%Pd/MN-270 were used in the hydrogenolysis of lignocellulosic material (softwood sawdust) to obtain liquid fuels in the form of hydrocarbons.

Sustainable Approaches to the Synthesis of Metallophthalocyanines in Solution

Molecules, 2021
This work aims to investigate more sustainable reaction conditions for the synthesis of metallophthalocyanines. Anisole, glycerol and their mixtures have been investigated as reaction media for the tetramerization of phthalonitriles.

Differential Sedimentation and Cryo‐TEM Mapping Resolve Structural Heterogeneity in Conjugated Polymer Nanowires for Programmable Stretchable Electronics

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.

Crystallographic and spectroscopic characterization of two 1-phenyl-1H-imidazoles: 4-(1H-imidazol-1-yl)benzaldehyde and 1-(4-methoxyphenyl)-1H-imidazole

Acta Crystallographica Section E: Crystallographic Communications, 2023
The title compounds, C10H8N2O, (I), and C10H10N2O, (II), are two 1-phenyl-1H-imidazole derivatives, which differ in the substituent para to the imidazole group on the arene ring, i.e. a benzaldehyde, (I), and an anisole, (II).

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 ...
