An exploration of market mechanisms to the wicked problem of space debris 太空垃圾棘手问题的市场机制探究 Una exploración de los mecanismos del mercado para resolver el complejo problema de los desechos espaciales

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.
Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...

Optimization method for self‐healing improver in fiber‐reinforced ceramics using SiC healing agent

open access: yesInternational Journal of Applied Ceramic Technology, Volume 22, Issue 5, September/October 2025.
Abstract An optimization method for lowering the effective self‐healing temperature of fiber‐reinforced self‐healing ceramics (shFRC) was investigated using B4C as a self‐healing improver. B4C was selected based on its ability to oxidize at lower temperatures than SiC, a typical self‐healing agent.

Combustion synthesis of Eu,Si‐doped AlN blue phosphor with varying Eu and Si concentrations

open access: yesJournal of the American Ceramic Society, Volume 108, Issue 9, September 2025.
Eu,Si‐doped AlN blue phosphors were synthesized via combustion synthesis using Al, AlN, Eu₂O₃, Si₃N₄, and SrCO₃. The luminescence properties were investigated concerning Eu and Si concentrations, as well as Sr substitution to mitigate Eu content.
