Leader Propagation Characteristics Under Positive Lightning Impulse Voltages

IEEE Access
Lightning strikes on transmission lines often generate overvoltage, which is the primary reason for insulator string flashover. This overvoltage, with a rapid rise time of just a few microseconds, causes leader propagation characteristics to differ ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Quaternary structures of Streptococcus pneumoniae nucleoside diphosphate kinase: From hexamers to supramolecular assemblies

Protein Science, Volume 35, Issue 9, September 2026.
Abstract The nucleoside diphosphate kinase (NDK) is a key enzyme that controls the balance of nucleotide pools in all living organisms. Beyond this fundamental role, NDKs exert pleiotropic effects in many cellular processes, including cell development, signal transduction, differentiation, tumor metastasis, and gene expression. The quaternary structure

Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle

steel research international, Volume 97, Issue 9, Page 4684-4713, September 2026.
Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Study on temperature rise prediction of ZnO varistors under multiple lightning strikes based on BP neural network and microscopic

High Temperature Materials and Processes
ZnO varistors are widely used in the field of lightning protection. After being struck by lightning, ZnO varistors absorb heat, which can lead to temperature rise and even damage, posing a serious safety threat to electrical safety.
