Flash sintering of zircon: rapid consolidation of an ultrahigh bandgap ceramic
Journal of Asian Ceramic Societies, 2021 Zircon (ZrSiO4) is a refractory structural ceramic material difficult to consolidate because of its thermal dissociation into ZrO2 and SiO2. Addition of sintering aids can improve its densification, but with detrimental effects on high temperature ...

Flash sintering of high-purity alumina at room temperature
Journal of Advanced Ceramics, 2023 For the first time, the flash sintering (FS) of high-purity alumina at room temperature, which was previously considered unachievable due to its low electrical conductivity, was conducted herein.

Non‐Equilibrium Synthesis of Whitlockite Assisted by Localized H2O Vapor Pressure
Advanced Science, EarlyView.A carbon substrate acts as a microheater during intense pulsed light irradiation, enabling rapid heating and cooling for whitlockite formation. In contrast to conventional white ceramic synthesis with weak photothermal response, this platform concentrates thermal energy locally and promotes phase‐selective crystallization under ultrafast ...

Carbon Energy, EarlyView.ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Carbon Energy, EarlyView.Pb/Ge/Br codoping in n‐type polycrystalline SnSe induces band convergence and high‐density dislocations, yielding a high power factor of 7.47 μW cm−1 K−2 and ultralow lattice thermal conductivity. Consequently, a peak ZT of 1.6 is achieved, overcoming the traditional performance limitations of n‐type SnSe.
