We reviewed these papers and proposed four potential ceramics groups for high‐entropy transparent ceramics including fluoride ceramics, fluorite‐deficient and/or ordered pyrochlore A 2 B 2 O 7 ceramics, garnet ceramics, and sesquioxide ceramics. In this article, we review ceramic powder synthesis,...

For example, adding fluoride salts to high-entropy oxides led to greater stabilities and higher working potentials (3.4 V vs. Li+/Li) for cathode materials81. Similar mixing, in principle, is adaptable to other systems such as 2D chalcogenides. Mixing in non-metal such as in 2D ...
The solvent evaporation has been identified able to induce the cocrystallization of dissolved polyvinylidene fluoride (PVDF) homopolymer and poly(vinylidene fluoride trifluoroethylene) (PVDF-TrFE) copolymer solutes in this research. Upon the random incorporation of either trifluoroethylene (TrFE) or vinylidene...
(a) Gibbs free energy of formation of different fluoride compounds at 700°C [102] and (b) Gibbs free energy of formation of different chloride compounds at 827°C [103]. Additionally, the higher diffusion coefficient of Mn hinders Cr dissolution. However, Cr was found to be associated with...

A new class of high-entropy M3B4 borides of the Ta3B4-prototyped orthorhombic structure has been synthesized in the bulk form for the first time. Specimens
First, 70% active materials (HESO), 20% conductive carbon black (Super P, Timcal, Billerica, MA, USA) and 10% polyvinylidene fluoride (PVDF, Alfa Aesar, Karlsruhe, Germany) were homogeneously mixed with N-methyl-2-pyrrolidone (NMP, anhydrous 99.5%, Sigma-Aldrich, Steinheim, Germany). The ...
In this study, we experimentally investigate the high stain rate and spall behavior of Cantor high-entropy alloy (HEA), CoCrFeMnNi. First, the Hugoniot equations of state (EOS) for the samples are determined using laser-driven CoCrFeMnNi flyers launched into known Lithium Fluoride (LiF) windo...
Since discovery of high entropy alloys (HEAs) in 2004, the concept of high entropy has been enlarged to ceramic, sulfide, fluoride, and phosphide materials. Correspondingly, their nearly infinite compositional space has been expanded to refractories, lanthanides, and recently platinum group metals (...
