Enhanced Hydrogen Release from Hydrogen Boride Nanosheets via Carbon Doping

open access: yesSmall Structures, Volume 6, Issue 12, December 2025.
This study reports the synthesis of carbon‐doped hydrogen boride nanosheets through an ion‐exchange approach. Carbon incorporation weakens BHB bonds, enhancing hydrogen release under thermal and ultraviolet stimuli. Spectroscopic analysis and density functional theory calculations confirm the structural and electronic changes, demonstrating carbon ...

Combustion synthesis of ultra‐high temperature ceramics: Review

open access: yesInternational Journal of Applied Ceramic Technology, Volume 22, Issue 6, November/December 2025.
Abstract Novel and future‐oriented aerospace, energy, transportation, and other industrial technologies require materials capable of operating at temperatures above 2000°C. Ultra‐high temperature ceramic materials (UHTCs), based on carbides, borides, carbonitrides, and nitrides of transition metals—many with melting points exceeding 3000°C—possess the ...

Elastic properties of hot-isostatically-pressed magnesium diboride [PDF]

open access: yesApplied Physics Letters, 2003
Magnesium diboride was hot-isostatically pressed using three qualitatively different cycles: dense material cooled under pressure (DMCUP), “standard” cycle with pressure and temperature simultaneously reduced, and isothermal pressure release. Elastic properties of dense MgB2 were measured at normal conditions using resonant ultrasound spectroscopy ...
