Hydrogen‐Free APCVD Synthesis of Heterophase WSe2 Nano‐Butterflies for Room Temperature NO2 Detection: Experimental and Computational Insights

Small Science, Volume 6, Issue 6, June 2026.
Scalable, hydrogen‐free atmospheric pressure chemical vapor deposition synthesis of heterophase 2H/1T′ WSe2 for ultrasensitive room‐temperature NO2 detection. Hierarchical nano‐butterfly morphology prevents restacking and maximizes active edges. Optimized phase engineering (~17% 1T′) enables fast charge transfer, achieving 40% response at 800 ppb, 4 ...

Mesoporous Copper‐Based Metal‐Organic Framework Flakes as a Promising Platform for Electrosynthesis of Ethylene from Carbon Dioxide

Small Science, Volume 6, Issue 6, June 2026.
We report a one‐pot green synthesis of a flake‐like, mesoporous Cu‐based metal‐organic framework for CO2 conversion. Its structure enhances mass transport and active‐site accessibility, promoting C–C coupling. In a zero‐gap cell, it achieves 51.6% C2H4 selectivity at 200 mA cm–2.

Torsional Vibration Analysis of Double‐Walled Carbon Nanotubes Incorporating Viscoelasticity and Nonlocal Elasticity Under Deformable Boundary Conditions

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 6, June 2026.
ABSTRACT This study investigates the torsional vibration characteristics of double‐walled carbon nanotubes (DWCNTs) considering viscoelastic effects and nonlocal elasticity theory. The equations of motion are formulated based on the nonlocal constitutive relations and viscoelastic material behavior to accurately capture the small‐scale and time ...

Nonlinear Evolution of Auroral Fine Structures Through the Feedback Instability in a Dipole Field Configuration

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Nonlinear simulations of the feedback instability in the Alfvénic magnetosphere‐ionosphere (M‐I) coupling system have been carried out by means of the reduced magnetohydrodynamic (MHD) equations with spatially non‐uniform kinematic viscosity and resistivity, coupled with two‐fluid equations, in order to investigate auroral fine‐structure ...

Cajon Pass and the Southern San Andreas Fault System: Earthquake Cycle Stress Accumulation and Present‐Day Loading

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract With over a century since the last major rupture affecting the wider Los Angeles region, tectonic stress has steadily built along the southern San Andreas and San Jacinto fault systems, raising concerns of an imminent large earthquake. Cajon Pass, located at the junction of these faults, represents a critical site for potential through‐going ...
