Isolation and screening of microorganisms from oil contaminated soil samples with biosurfactant producing ability was investigated. The biosurfactant producing ability of the microorganisms isolated from the soil samples was investigated by hemolytic assay, drop collapse test, emulsification index and methylene blue agar plate method. The best isolate was identified as Pseudomonas aeruginosa ba...

Highly ordered mesoporous inorganic-organic hybrid thin films with covalently bonded carboxylic acid (-COOH) terminal groups on the pore surfaces were synthesized by evaporation induced self-assembly of tetraethoxysilane, organosilanes, and a nonionic surfactant followed by acid hydrolysis and characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform...

A biomolecule namely pyocyanin was isolated from Pseudomonas aeruginosa (BTRY1). It was confirmed by UV-Vis spectrum with absorption maxima at 270 nm and was further characterized using Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR). Spectroscopy analyses showed the presence of relevant bonds in their respective structures. Although pyocyanin had antihemolytic, antioxida...

The aim of the present study was to develop a sustained release monolithic system for the low solubile/low dose glipizide, for the treatment of type II diabetes mellitus. The matrices were prepared by dry blending of polymers hydroxy propyl methyl cellulose (HPMC) or erodible Eudragit (ammonio methacrylate copolymers) and other excipients using direct compression method and were characterized u...

The thermo physical parameters thermal effusivity (e) and thermal diffusivity (α) have been measured using Fourier transform infrared (FTIR) Photoacoustic spectroscopy (PAS) for two different purities of C60 fullerenes (99.5 % , 98.5%) samples in the powder form. The experimental results shows that the values of thermal diffusivity is less then that obtained for crystalline C60 fullerenes. The ...

the knoevenagel condensation of aromatic aldehydes with barbituric acid, dimedone and malononitrile occurred in the presence of bf3/nano-γ-al2o3 at room temperature in ethanol. this catalyst is characterized by powder x-ray diffraction (xrd), fourier transform infrared spectroscopy (ft-ir), thermal gravimetric analysis (tga), field emission scanning electron microscopy (fesem) and energy-disper...

In this study Klason lignins from Eucalyptus grandis (LEUG) and Pinus taeda (LPIT) were characterized using Fourier transform infrared (FTIR) spectroscopy and thermogravimetry (TGA). The degradation kinetic parameters were determined by TGA using the Kissinger method. Thermogravimetric results showed that LPIT had higher thermal stability and also higher activation energy than LEUG. FTIR result...

The recent development of Fourier transform infrared (FTIR) spectroscopic imaging has enhanced our capability to examine, on a microscopic scale, the spatial distribution of vibrational spectroscopic signatures of materials spanning the physical and biomedical disciplines. Recent activity in this emerging area has concentrated on instrumentation development, theoretical analyses to provide guid...

Internal erosional behaviour of lignosulfonate treated dispersive clay has been studied using the Process Simulation Apparatus for Internol Crack Erosion (PSAICE) designed and built at UOw. Effectiveness of Iignosulfonate treated dispersive clay on the erosion resistance has been investigated and its advantage over traditional admixtures is presented. Test results show that the hydraulic shear ...
