Non‐Equilibrium Synthesis of Whitlockite Assisted by Localized H2O Vapor Pressure
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 ...

High‐entropy doping of Co‐free Ni‐rich LiNiO2 cathodes is achieved through a scalable 3D mixing process. Multi‐element incorporation stabilizes the layered structure, alleviates Li/Ni disorder and electrode swelling, and enhances cycling stability. This approach underscores the potential of high‐entropy strategies to deliver structurally robust and ...

Development of master sintering curve for field-assisted sintering of HfB2-20SiC
Field assisted sintering (FAST) or spark plasma sintering (SPS) has emerged as a promising technology for densification of ultra high temperature ceramics like HfB2-20SiC at relatively low temperatures and shorter times. In the present study the concepts

Densification and preservation of ceramic nanocrystalline character by spark plasma sintering [PDF]
Spark plasma sintering is a hot pressing technique where rapid heating by dc electric pulses is used simultaneously with applied pressure. Thus, spark plasma sintering is highly suitable for rapid densification of ceramic nanoparticles and preservation ...

An Assisting Contact Electrification Strategy for Achieving Self‐Recoverable Mechanoluminescence
ABSTRACT Self‐recoverable mechanoluminescence (ML) is a unique property of materials that can stably emit light under repeated stress, enabling new applications in smart sensing, displays, and wearable devices. However, self‐recoverable ML is very rare and only observed in a few active phosphors excited by piezoelectricity or contact electrification ...

Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude
