β-CuGaO2 is a wurtzite-derived phase that promising for ferroelectric and photovoltaic applications. Its bandgap measured in the form of powders about 1.5 eV direct according to density functional theory calculations, making it an appropriate solar light absorber. In this work, we describe our attempts grow complex by pulsed laser deposition (PLD) resulted growing mostly CuGa2O4 on various crys...

Introduction. In addition to good biological properties, biomaterials should also possess appropriate physical properties in order provide stability and longevity at the place of application. The aim this work was evaluate an experimental nanostructured material based on calcium aluminate (CAL) silicate (CS). Material method. research used synthesized by hydrothermal solgel method from individu...

The phenomenon of evanescent-wave scattering (EWS) is used to design an optical-fiber humidity sensor. Porous solgel silica (PSGS) coated on the surface of a silica optical-fiber core scatters evanescent waves that penetrate the coating layer. Water molecules in the gas phase surrounding the optical fiber can be absorbed into the inner surface of the pores of the porous silica. The absorbed wat...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

In this study, calcium phosphate nanoparticles with two phases, fluorapatite (FA; Ca(10)(PO(4))(6)F(2)) and hydroxyapatite (HA; Ca(10)(PO(4))(6)(OH)(2)), were prepared using the solgel method. Ethyl phosphate, hydrated calcium nitrate, and ammonium fluoride were used, respectively, as P, Ca, and F precursors with a Ca:P ratio of 1:72. Powders obtained from the sol-gel process were studied after...

Concatenative synthesis is currently the favoured approach to text-to-speech synthesis, yet it has fundamental limitations. In the longer-term, articulatory synthesis has much greater potential. Different approaches to articulatory synthesis are discussed in terms of the choices made concerning the articulatory processes modelled, the simplifying assumptions, and the data collected.

Magnetic powder of Sr-ferrite was prepared by conventional and sol-gel auto-combustion methods. In conventional method, strontium carbonate and ferric oxide powders were mixed together and then mixture was calcined. In sol-gel auto-combustion method, a solution containing strontium nitrate, ferric nitrate and citric acid was heated until the combustion took place automatically; then, as-burnt p...
