A review of high-entropy ceramics preparation methods, properties in different application fields and their regulation methods

Journal of Materials Research and Technology
High-entropy alloys (HEAs) provides a new way to develop new materials with adjustable performance due to their unique cocktail effect. Inspired by HEAs, a ceramic material with high-entropy effect has been developed, which was named high-entropy ...

Shock-induced melting of MgSiO_3 perovskite and implications for melts in Earth's lowermost mantle [PDF]

, 2004
New shock wave equation of state (EOS) data for enstatite and MgSiO_3 glass constrain the density change upon melting of Mg-silicate perovskite up to 200 GPa. The melt becomes denser than perovskite near the base of Earth's lower mantle.

Porous Coatings by Vapor Sublimation and Deposition for Molecular Channeling and Filtration in an Interstitial Fluid Microfiltration Device

Advanced Healthcare Materials, EarlyView.
A vapor‐based porous coating applied within nitinol tubes demonstrated complete suppression of cellular and tissue ingrowth, overcoming a major limitation of implantable interstitial fluid collection devices. Molecular channeling and diffusion are analyzed with probe molecules, showing reliable transport in vitro and in vivo. The coating also achieved >

Gentamicin‐Loaded Carbonate Apatite with Dual Antibacterial and Osteogenic Functions for Combating Surgical Site Infections

Advanced Healthcare Materials, EarlyView.
A bone substitute with gentamicin physically precipitated onto the surface of carbonate apatite exhibits prompt drug release, high bactericidal activity, and osteogenic capacity. Efficient antibacterial activity mitigates early postoperative neutrophil accumulation, the status of which may serve as a potential parameter for evaluating the antibacterial
