Comparative Density Functional Theory Insights Into B16C16 and Si16C16 Nanocages for Sensing Oil‐Derived Fault Gases in Energy and Industrial Systems

open access: yesChemistryOpen, Volume 15, Issue 6, June 2026.
B16C16 and Si16C16 nanocages were investigated via DFT for sensing transformer oil fault gases (C2H4, CO, H2S). BC nanocages exhibit stronger adsorption, reduced energy gaps, enhanced electrical conductivity, and positive sensing responses compared to SiC. NCI and QTAIM analyses reveal covalent and partially covalent interactions.

Quantum Information Measures of a Dirichlet Waveguide with Neumann Window(s)

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
ABSTRACT Engineering boundary conditions in low‐dimensional structures provides a simple yet powerful way of shaping how quantum information is stored and transported. We investigate a flat 2D Dirichlet waveguide containing one or two finite Neumann windows and compute the bound states in both position and momentum space as functions of the window ...

On‐Surface Synthesis of B3N3‐Substituted Two‐Dimensional Covalent Organic Frameworks with Distinct Pore Sizes and Kagome Band Structures

open access: yesSmall, Volume 22, Issue 32, 8 June 2026.
Single‐layer, 2D BN‐substituted covalent organic frameworks (COFs) with two distinct periodicities are synthesized on noble metal supports. A multi‐method characterization reveals a non‐planar, chiral structure. Band gaps and frontier band dispersion are controlled by linker chemistry and spacer extension.

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

open access: yesJournal 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 ...
