Highly ordered TiO2 nanotube arrays on Ti substrates were prepared by an electrochemical anodization process in a mixture of glycerol and water containing 0.5 wt% NH4F and then thermally annealed from 400 C to 600 C. The sample structures were characterized by scanning electron microscopy and X-ray diffraction measurements, where the nanotube pore diameter and length were found to increase with...

This research investigates the removal of textile dyes (Rhodamine B and Alizarin Red S) from aqueous solution by a low-cost adsorbent prepared eggshell waste. Batch adsorption experiments were conducted in order to determine effect different parameters such as pH, dye concentration, contact time, dosage, particle <br /> size, temperature. The best correlation was found Langmuir model, max...

Polarised light microscopy of synovial fluid is an established diagnostic technique widely regarded as reliable for the detection of crystals. The threshold concentration of crystals which can be detected has been investigated and the sensitivity and specificity of six observers compared. Various concentrations of laboratory manufactured crystals of monosodium urate monohydrate (MSUM), calcium ...

bone matrix gelatin (bmg) has been used for bone induction intramuscularly and subcutaneously by many investigators since 1965. more recently, some of the researchers have used bmg particles for bone repair and reported various results. in present study for evaluation of bone induction and new bone formation in parital defects, bmg particles were used in five groups of rats. the bmg was prepare...

A combined spectroscopic and computational approach has been used to study in detail the complexation between Ga(III) ARS solution. The NMR results revealed formation of four Ga(III)/ARS complexes, at pH 4, differing their metal:ligand stoichiometries or configuration, point a coordination mode through ligand positions C-1 C-9. For equimolar solutions, 1:1 [Ga(ARS)(H2O)4]+ complex was formed, w...
