In this article we describe work on the synthesis of bolaphile biomimics composed of glucose head groups and steroidal units linked together by a methylene chain of varying length. The condensed phases formed by self-organization of the products as a function of temperature were characterized by ...

Pure and Eu3+-doped yttrium hydroxide fluoride (YHF) monodisperse mesocrystals were fabricated via an additive-free hydrothermal route. Each of the cantaloupe-like architectures is an assembly of aligned nanorod subunits in a side-by-side manner. The Eu3+-activated YHF mesocrystals exhibited ...

We have developed a fast, easy, and scalable synthesis method for Ba1–xKxFe2As2 (0 ≤ x ≤ 1) superconductors using hydrides BaH2 and KH as a source of barium and potassium metals. Synthesis from hydrides provides better mixing and easier handling of the starting materials, consequently leading to ...
