Experimental demonstration of sustained entirely detached growth in the vertical directional solidification (VDS) configuration under terrestrial gravity: A dynamic capillary-gravity stability criterion of entirely detached solidification for the long length

This paper experimentally demonstrates that sustained entirely detached growth of antimony-based semiconductor crystals can be achieved under terrestrial gravity in a vertical directional solidification configuration using conical-bottom quartz ampoules, which stabilize the crystal-ampoule gap and improve crystallization quality by suppressing wall-induced defects.

Work Functions at Work: Observing Contact Electrification at Individual Metal–Metal Heterojunctions

By combining off-axis electron holography with orbital-free density functional theory, this study quantitatively reveals that work-function differences drive charge redistribution not only at individual metal–metal heterojunctions but also across their external surfaces, thereby providing a new framework for probing local contact potentials and understanding metal–support interactions at the single-particle resolution.

Optimization of microstructure and electrical properties of ZnO-Cr2O3-based varistors by Tm2O3 doping

This study demonstrates that optimizing Tm₂O₃ doping at 0.50 mol% significantly enhances the electrical performance of ZnO-Cr₂O₃-based varistors by refining grain size and increasing grain boundary barrier height, resulting in a high voltage gradient, superior nonlinear coefficient, and low leakage current.

Effect of Applied-Force Misalignments on Rolling Resistance Measurements Using the Force Method

This study demonstrates that force-based rolling resistance measurements are highly sensitive to geometric misalignments and validates a theoretical model capable of accurately predicting and correcting these alignment-induced errors across both flat and cylindrical testing surfaces.

The Ultrafast Dynamics of Two-dimensional Bi2TexSe3-x Nanosheets

This study utilizes time-resolved photoluminescence and pump-probe techniques to investigate the ultrafast dynamics of Bi2TexSe3-x nanosheets, revealing that increasing selenium content induces a dominant mechanism reversal from carrier recombination to thermal effects, evidenced by shifting PL lifetimes and accelerated electron-phonon relaxation.
