This study explores the impact of laser annealing on electrical and magnetic properties nano boron deposited oxidized porous silicon (n-B/PSiO2) its potential for spintronic applications. The Nd: YAG was used at varying energies to anneal n-B thin films. Increasing energy increased grain size more ordered structures. It also surface roughness due forming new boundaries secondary phases. materia...

Zeolites due to their structures can be used as molecular sieves for purification of materials and solutions. Zeolites with PHI and SOD structure are so common and applicable for this purpose. Hydroxy sodalite and phillipsite are the more abundant members of zeolites which display good selectivity for very small molecules and some ions such as Sr, Pb, Zn, Cu and Rb. There is not any pure natura...

A nano-hydroxyapatite/collagen composite was prepared by precipitation of hydroxyapatite from an aqueous solution onto collagen. Mouse peritoneal macrophages were used to investigate the in vitro biodegradation of the composite. The results showed the mechanism of phagocytosis and extracellular degradation process. The cells that belong to the mononuclear phagocyte system showed some morphologi...
