Microstructure and magnetic properties of amorphous Fe51Co12Si16B8Mo5P8 alloy

Fe-based metallic glasses such as FINEMET, NANOPERM and HITPERM usually produced from amorphous precursors in various forms have been intensively studied over the past thirty years, because these materials exhibit a unique combination of soft magnetic properties [1], which is very interesting from a scientifi c point of view. The application of these materials at elevated temperatures is determ...

Use of calcined Mg-Al-hydrotalcite to enhance the stability of celecoxib in the amorphous form.

The use of compound in amorphous forms is a promising approach to improve solubility of poorly water-soluble drugs. However, during storage, amorphous state can spontaneously transform to the lower energy crystalline form and this is a limiting factor for a large commercial use of drugs. In this paper, calcined hydrotalcite was employed to support amorphous celecoxib and several preparations at...

Synthesis, microstructure and thermal properties of photoluminescent hydrogenated amorphous silicon oxide nanopowders

Hydrogenated amorphous silicon oxide photoluminescent nanopowders have been synthesized using a simple solution method involving the reaction of lithium with trichlorosilane in tetrahydrofuran at room temperature. The powders exhibited maximum luminescent peak at 1.1 eV and had an average composition of SiO0.92H0.53. They possess inhomogeneous microstructures that contain a-Si clusters (Si3–Si–...
