Wide Band Gap Boron Nitride Nanodots‐Incorporated Polyetherimide Dielectrics for High‐Temperature Dielectric Energy Storage

open access: yesAdvanced Science, EarlyView.
The inherent conjugation effects between molecular chains in PEI dielectrics induce substantial energy loss escalation at elevated temperatures. This study incorporated BNNDs into PEI films, successfully achieving effective capture of motion charges under high‐temperature conditions.

Cathodoluminescence spectroscopy of monolayer hexagonal boron nitride

open access: yesScientific Reports
Cathodoluminescence (CL) spectroscopy is a suitable technique for studying the luminescent properties of optoelectronic materials because CL has no limitation on the excitable bandgap energy and eliminates ambiguous signals due to simple light scattering

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

open access: yesAdvanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Salt Water Drops Slide Faster: Ionic Modulation of Drop Friction

open access: yesAdvanced Science, EarlyView.
Salt ions markedly accelerate water drops on conductive substrates coated with nanometer‐thin hydrophobic layers. Across diverse electrolytes and surfaces, higher ion concentration consistently lowers kinetic friction by reducing contact angle hysteresis.

Les Variations Rapides Du Champ Magnetique Et Des Courants Tellurques

open access: yesBulletin of the Mineral Research and Exploration, 1955
Je tiens d'abord à remercier le Professeur Hamit Nafiz Pamir pour sa très aimable et très flatteuse invitation, et à m'excuser si un géophysicien qui n'a jamais fait lui-même de véritable prospection se permet de vous donner des leçons.

Coulomb Calligraphy

open access: yes, 2023
PUBLISHED The equilibrium configurations of N Coulomb charges confined by a harmonic potential in two dimensions are found to exhibit a wide variety of patterns that are pleasing to the eye, when adjacent points are joined up. We present a selection of these for N=50.

Superradiance and Broadband Emission Driving Fast Electron Dephasing in Open Quantum Systems

open access: yesAdvanced Science, EarlyView.
We uncover the physical origin of ultrafast electron dephasing in solid‐state high‐harmonic generation by simulating the Lindblad equation for the dissipative Hubbard model. Coexistence of Dicke superradiance and broadband emission is revealed, whose destructive interference shortens the effective scattering time and provides a unified picture of ...

Directional Regulation of Zinc Deposition Through Constructing Hierarchical Janus Carbon Matrix with Organic‐Decorated Multi‐Channels

open access: yesAdvanced Science, EarlyView.
A Janus carbon matrix is engineered by covalently anchoring organic sulfonic anions within tubular pores of hierarchical CMK‐5, serving as an interfacial layer for Zn metal anodes. This design establishes a charge gradient for Zn2+ diffusion, enabling the directional deposition of confined and uniform Zn inside the pores while suppressing parasitic ...
