In this letter, we report on the obtention of hafnium oxide (HfO(2)) nanostructures by the microwave-hydrothermal method. These nanostructures were analyzed by X-ray diffraction (XRD), field-emission gum scanning electron microscopy (FEG-SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectrometry (EDXS), ultraviolet-visible (UV-vis) spectroscopy, and photoluminescence (PL...

Celecoxib spherical agglomerates were prepared with polyvinylpyrrolidone (PVP) using acetone, water and chloroform as solvent, non-solvent and bridging liquid, respectively. The agglomerates were characterized by differential scanning calorimetry (DSC), X-ray diffraction (XRD), IR spectroscopic studies and scanning electron microscopy (SEM). The IR spectroscopy and DSC results indicated the abs...

Several techniques have been utilized for the preparation of hydroxyapatite (HA) and other calcium phosphates for the development of biomaterials. It is vital to know the reaction kinetics to be able to control the material obtained by the aqueous solution route. In the present work, HA has been produced by different wet precipitation processes and different experimental conditions. Calcium hyd...

Mucoadhesive polymeric suspension of Ofloxacin was prepared and optimised with the aim of developing oral controlled release gastro-retentive dosage form. Ofloxacin was standardized by UV Spectroscopic analysis. The qualitative analysis of the formulation was performed by FTIR, XRD and SEM analysis. The results from FTIR study indicated that the mucoadhesive suspension of Ofloxacin showed a ver...

Hydroxyapatite powder has been prepared via sol-gel procedure using calcium nitrate tetrahydrate and diammonium hydrogen phosphate as the precursors for calcium and phosphorus, respectively. XRD measurement shows that the powder contains hydroxyapatite crystals with β-TCP and calcium oxide as secondary phases. Hydroxyapatite powder of higher purity, i. e., the correct Ca/P ratio, has been obtai...

Presently, the ferrites industry consumes large amounts of iron osides obtained by spray roasting of steel pickling liquors. The aim of this paper is to propose the synthesis of optimal iron osidcs by oxyprecipitation of steel pickling liquors in order to obtain Bahexafenite wit11 high magnetic properties using the ceramic process. As a raw material. i t was used sulphuric liqoors with iron con...

The purpose of this study is to understand mineral diagenesis authigenic mineral and the effect of climate on mineral of Pleistocene-Holocene sediment deposits in the Southern Kenya Rift. Lake Magadi unique geologic settings are characterized by extreme alkalinity and high silica activities. The mineralogical analysis was achieved by X-Ray diffraction (XRD) and Scanning Electron Microscopy (SEM...

The emerging of nanoparticles into the living system especially for medical purposes has opened up a new challenge of synthesizing them in a benign fashion. In the present study, 5 endophytic fungi were isolated from the mangrove leaves of Rhizophora annamalayanna and among that A. terreus was produced the AgNPs extracellularly and the presence of AgNPs was confirmed by XRD, SEM with EDX, TEM a...
