Enhanced Ablation Resistance of Phenolic Resin at 1400–2300 °C through Zirconium-Doping-Induced Heterogeneous Melt Strengthening and Graphitization Transition

Abstract Boron oxide derived from boron-phenolic resin suffers severe viscosity reduction and volatilization at high temperatures, failing to form a robust ceramic melt layer and severely limiting its application in hypersonic vehicles. We designed a zirconium-doped polyborosilan...

Ionic Liquid-Mediated Structure-Engineered Cellulose-Based Ionogel with Ion-Electron Cotransport for Boosted Thermoelectric Conversion

Abstract Low-grade heat (<373 K) remains an underutilized energy source due to inefficient conversion technologies. While ionic thermoelectric (i-TE) materials show promise for direct thermal-to-electrical energy conversion, simultaneously optimizing the conductivity and Seebeck...
