Influence of grinding and pressing of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure and magnetic properties [PDF]

Science of Sintering
Mixing the powders Fe (50.0 wt%), BaTiO3 (47.0 wt%) and TiO2 (3.0wt%) provides a mixture consisting of a matrix of smaller particles BaTiO3 in which larger particles Fe and TiO2 were embedded.

Processes at lithium-hydride/deuteride surfaces upon low energy impact of H/D

Frontiers in Physics, 2023
Sputtering, reflection, and retention processes at amorphous and crystalline lithium hydride surfaces due to impact of low energy (1–100 eV) hydrogen and deuterium atoms over the range of 0o −85o angle of incidence at 300 K surface temperature were ...

Kinetically Controlled Two-Step Amorphization and Amorphous-Amorphous Transition in Ice

Physical Review Letters, 2017
We report the results of in situ structural characterization of the amorphization of crystalline ice Ih under compression and the relaxation of high-density amorphous (HDA) ice under decompression at temperatures between 96 and 160 K by synchrotron x-ray diffraction.

Photocatalytic Crystalline and Amorphous TiO₂ Nanotubes Prepared by Electrospinning and Atomic Layer Deposition

Molecules, 2021
In this work core/shell composite polymer/TiO2 nanofibers and from those TiO2 nanotubes were prepared. First, poly(vinyl alcohol) (PVA) and poly(vinylpyrrolidone) (PVP) fibers were synthetized by electrospinning.

Influence of grinding, pressing and sintering of the powder 50.0 wt% Fe, 47.0 wt% BaTiO3 and 3.0 wt% TiO2 on morphology, microstructure, magnetic and electric properties [PDF]

Science of Sintering
A mixture of 50.0 wt% Fe, 47.0 wt% BaTiO3, and 3.0 wt% TiO2 powders is milled and then pressed and sintered. Samples sintered from ground powders have a structure consisting of plates.

Synthesis and Characterization of Optically Transparent Ceramic Crystalline/Amorphous and Amorphous/Amorphous Multilayers

SSRN Electronic Journal, 2020
Optical nano multilayers (NMs) are promising candidates for durable transparent multifunctional coatings, although the contribution of interfaces and high transparency configurations has yet to be explored. To address this, high transparency NMs (%T380-1100nm≈94-99%) were synthesized by magnetron sputtering, and the effects of crystalline/amorphous ...
