The combination of multiple-principal element materials, known as high-entropy materials
(HEMs), expands the multi-dimensional compositional space to gigantic stoichiometry. It is …

Over the past six years (2015±2021), many superconducting hydrides with critical
temperatures Tc up to+ 15 C, which are currently record high, have been discovered. Now …

Since the discovery of superconductivity at~ 200 K in H3S, similar or higher transition
temperatures, T cs, have been reported for various hydrogen-rich compounds under ultra …

This paper shows that the combination of self-assembled structures in the form of “whiskers”
and nanoparticles, which appear as a result of the joint sintering powders YBa2Cu3O7Àx …

An extended critical state model has been developed. The model has considered the
equilibrium magnetization of a surface layer and the magnetization of the central region of a …
