The effect of gamma-ray irradiation on the mechanical properties of Zr55Ni5Al10Cu30 bulk metallic glass (BMG) was investigated. The samples were irradiated with a gamma-ray dose up to 2090.24 kGy prior to mechanical property investigations. Vickers hardness test, nano-indentation test as well as speed of sound measurements in order to calculate the material’s elastic moduli were conducted. An x...

Thin films of silver selenide have been prepared by chemical bath deposition technique at substrate temperature of 300K. The films were characterized by X-ray diffraction and UV-VIS spectrophotometer. Silver selenide thin films are polycrystalline with orthorhombic structure, confirmed by x-ray diffractogram. The deposition parameters were optimized to obtain good quality thin films. The film d...

Prednisolone is a safe antiinflammatory agent for the treatment of inflammatory diseases. To improve the aqueous solubility of the drug and dissolution rate, the complexation of prednisolone with skimmed milk was studied. A physical mixture and solid dispersion of prednisolone with skimmed milk were prepared. The lyophilization method was used to prepare the solid dispersion. Detection of inclu...

Bi4Ti3O12 is a tri-layer Aurivillius member compound that was reported to have good photocatalytic properties. Metal element doping and morphological particle tuning are strategies increase photocatalyst activity. In this research, the micro sheets Bi4Ti2.95V0.05O12 were synthesized using molten NaCl/KCl salt. The diffractogram shows sample successfully synthesized, however, there still found i...

Mixing aqueous solutions of sodium diclofenac (DIC-Na) and ranitidine hydrochloride (RAN·HCl) afforded an off-white solid (DIC-RAN) that was investigated from the microscopic, thermal, diffractometric, spectroscopic, and functional (chemometrics-assisted dissolution) points of view. The solid has a 2:1 (DIC:RAN) molar ratio according to (1)H nuclear magnetic resonance spectroscopy. It is therma...

This paper is the first multi-scale characterization of the fluidize-dried gum extracted from the fresh fruits of the plant Abelmoschus esculentus. It describes the physical, thermal, sorptional and functional properties of this natural gum. Elemental analysis, scanning electron microscopy (SEM), particle size analysis, X-ray powder diffraction (XPRD), thermo-gravimetric analysis (TGA), differe...

We assess the imaging performance of a transmission electron microscopy (TEM) system operated at a relatively low acceleration voltage using the three-dimensional (3D) Fourier transform of through-focus images. Although a single diffractogram and the Thon diagram cannot distinguish between the linear and non-linear TEM imaging terms, the 3D Fourier transform allows us to evaluate linear imaging...

The four-layered Aurivillius SrBi4Ti4O15 compound has been reported to be potentially used as a photocatalyst material. In this research, was prepared by the molten salt method using NaCl/KCl and then degrade methylene blue. analysis of sample diffractogram indicated that obtained but there still impurities Bi4Ti3O12. micrograph showed particle shape is plate-like (sheets) with lot agglomeratio...

A widely used performance criterion in high-resolution transmission electron microscopy (HRTEM) is the information limit. It corresponds to the inverse of the maximum spatial object frequency that is linearly transmitted with sufficient intensity from the exit plane of the object to the image plane and is limited due to partial temporal coherence. In practice, the information limit is often mea...
