Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Calcium carbonates, ground and precipitated, have an established role in material engineering where they serve as fillers and pigments. In this study monohydrocalcite (MHC) was produced from artificial industrial waste brines as a means of sequestering CO₂, and assessed as a potential functional filler, where its properties were compared with other minerals used in the industry. The results from the morphological analysis which compared MHC with the shapes and sizes of filler crystall...

This study deals with the grinding of mill scale in a laboratory ball mill for different milling time then briquetted by using 2% molasses as a binder and investigates the effect of grinding of mill scale for different time on the physicochemical properties and the reduction degree of the mill scale briquettes via hydrogen. Diffusion process control equation was applied and the energy of activation was calculated = 28.33 kJ/mole.

A fire resistant metakaolin geopolymer is developed and its performance under thermal loading is examined in this paper. The geopolymer was prepared by mixing metakaolin, doped with solid SiO₂, with a highly alkaline potassium hydroxide aqueous phase in order to create a paste that was subsequently cured at 70℃ for a certain period of time. The addition of solid SiO₂ was important in order the geopolymer developed to be fire resistant for temperatures up to 1350℃. The mecha...

Metronidazole is a derivative of benzimidazole. It is being used widely for the treatment of amoebiasis. An efficient, simple and least time consuming spectrophotometric method for the assay of metronidazole has been developed. Comparison of assay of three different brands of metroni-da- zole has also been available in public medical stores of Karachi, Pakistan. The assay is based on the ultraviolet UV absorbance maxima at about 340 nm wavelength of metronidazole using water as solvent. A sample...

Reduction kinetics of titanomagnetite concentrate briquettes produced from Rossetta-llmenite ore via 1.5 liter/min hydrogen flow rate were investigated at different temperatures ranging from 600℃ to 950℃. It was found that the best reduction properties were found at 950℃, so the kinetic models shown by the briquettes at this temperature maybe: Diffusion control or Diffusion through ash layer (crank-cins

The first investigation and analysis of 59Co 2D NMR homonuclear chemical shift correlation spectra for a ruthenium-based tetrahedral mixed-metal cluster HRuCo3(CO)11(PPh3) are reported. For this cluster in solution and by contrast to the conventional COSY NMR experiment, the double-quantum filtered (DQF) COSY NMR spectrum proves the existence of a scalar coupling constant between 59Co nuclei. In order to obtain a value of this coupling, the 2D COSY spectrum for a three-spin 7/2 AX2 system has be...

In this theoretical study we used density functional theory to calculate the molecular structures of Silver Halo compound, AgF3. The molecular geometry, vibrational frequencies, energies and natural bond orbital (NBO) in the ground state are calculated by using the DFT (B3LYP) methods with LANL2DZ. The T.S guesses were generated by the linear synchronous transit method, at the DFT implemented on Gaussian 98 program. The geometries and normal modes of vibrations obtained from B3LYP calculations a...
