Spontaneous and photo-induced crystallization have been investigated in fluorinated silicate glass by means of X-ray diffraction and optical interferometry. This glass is a photo-sensitive material for high-efficiency phase volume hologram recording. Variations of a refractive index in this glass are controlled by UV irradiation followed by a thermal development which is photo-thermo-refractive...

Abstract There are various methods to produce iron based nano crystalline magnetic alloys. Among these methods, mechanical alloying is one of the most important. In this research, nano crystalline Fe85Si10Ni5 soft magnetic alloy was synthesized by mechanical alloying. The effect of alloying time on phase constituents and magnetic properties of the produced powders was investigated, by X-ray di...

The current study deals with the development of glutaraldehyde crosslinked chitosanbased delivery system with improved mechanical properties utilizing reactive solvent technique. The prepared systems were characterized by Fourier Transform Infrared (FTIR) spectroscopy, x-ray diffraction (XRD), thermo gravimetric analysis (TG) and differential scanning calorimetry (DSC). The systems were also an...
