Kinetic Insights Into Boron–Carbon Interaction Under Programmed Heating

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
This work demonstrates the decisive role of the heating rate and short‐term mechanical activation in governing the boron–carbon interaction. The combined effect of rapid heating and mechanical activation enables the 4B + C reaction to proceed at significantly lower temperatures. For the first time, the effective activation energy of the 4B + C reaction

Influence of Backside Surface and Subsurface Damage in Gallium Nitride Wafers on Facet Quality and Violet‐Emitting Laser Diode Performance

physica status solidi (a), Volume 223, Issue 14, 22 July 2026.
Backside thinning techniques critically influence GaN laser performance. Compared to lapping, grinding reduces subsurface damage depth fivefold and lowers wafer bow, while mechanical polishing eliminates subsurface damage entirely. These improvements directly translate to smoother cleaved facets and a nearly 40% reduction in laser threshold current ...

Design of B,N Co‐Doped Carbon Spheres for Highly Effective Back Interface Engineering in Planar Carbon‐Based Perovskite Solar Cells

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
The energy level mismatch of the perovskite/carbon back interface is decreased remarkably by using B, N co‐doped carbon sphere electrode in C‐PSCs, leading to effective charge carrier separation, extraction, and transport at the back interface. Combined with further buried modification using AMPA, the power conversion efficiency of the C‐PSCs is up to ...

Effect of Microstructure on Mechanical Properties and Erosive Wear of B4C and B4C-CrB2 Composites.

Journal of the Ceramic Society of Japan, 2003
Monolithic B4C and B4C-20 mol% CrB2 composite ceramics were fabricated by hot pressing at 1900 and 2050°C. Erosive wear by Al2O3 particle impingement was tested using a sandblaster. The microstructure, mechanical properties and erosive wear of the ceramic specimens were examined and compared with those of a commercial B4C ceramic.
