We report our continued progress on the development of a thermochemical model of aluminum silicate mineral solubilities in aqueous solutions containing H, Na, K, Al, Cl, Si(OH)4, SiO(OH)3 , OH, Al(OH), Al(OH)2 , Al(OH)3 , Al(OH)4 − as a function of pH to high salt concentrations (I ≤ 5 m). Prior conference proceedings outlined our progress in developing an accurate model for the potassium free ...

Perpendicular magnetic tunnel junction with MgAl2O4 barrier is investigated. It found that reactive RF sputtering O2 essential to obtain strong perpendicular anisotropy and large tunneling magnetoresistance in MgAl2O4-based junctions. An interfacial energy density of 2.25 mJ/m2 obtained for the samples annealed at 400C. enhanced 60% has also been achieved. The Vhalf, bias voltage which drops ha...

A study was carried out to find out efficiency of rice bran in removal of heavy metals such as lead and cadmium from bisolute system. The different experimental conditions such as temperature, adsorbent amount, adsorbent particle size and concentration were studied. The results showed that 100% removal was achieved for both lead and cadmium by using rice bran at 300C, contact time 100-140 minut...

Nonstoichiometric nickel–copper spinel manganites were found to be highly active for the reduction of nitric oxide by carbon monoxide at low temperature (300C). The activity increases with the level of nonstoichiometry of the oxides and almost linearly with their specific surface area. Moreover, this activity was found to depend strongly on the copper content, nickel manganites being almost ina...

As industrially produced solar cells become thinner and more efficient, silicon nitride (SiN) films are becoming increasingly important. At present, the favored means of producing these films is by remote plasma-enhanced chemical vapour deposition (RPECVD). In this paper, using films produced by an industrial Roth & Rau SiNA RPECVD reactor, we investigate the surface passivation qualities of Si...

This paper reports the performance of nickel oxide based electrode in alkaline anion exchange membrane water electrolysis. The membrane used is polystyrene based alkaline membrane and the electrode used is Nickel as cathode and Nickel oxide as anode. The electrochemical activity of the Nickel oxide is high compared to uncoated electrode. The AWE membrane electrode gave high current density at 3...

Sustained release tablets of Rosuvastatin were developed to prolong r e l e a s e o f time leading to an increase in drug bioavailability.Tablets are prepared by direct compression technique using polymers HPMC K15M,HPMC K50M and ethylcellulose.Tablets were evaluated for their physical characteristics viz.,hardness, thickness, friability and weight variation, drug content and floating propertie...

Screening of the brine samples of a solar saltern has yielded one moderately halophilic protease producing bacteria. The bacterial isolate has been identified as a Pseudomonas sp. and it produced an extracellular protease and an amylase. Maximal protease production was detected at the early stationary phase. The enzyme showed the highest activity at 400C and pH 8.0 in 15% NaCl. The enzyme was a...

The bacteriocinogenic strain Lactobacillus paracasei spp. BN ATC 8w was isolated from traditional «Motal» cheese and has strong antimicrobial activity against some Gram-positive Gram-negative bacteria. in situ of the studied skimmed milk E. coli ATCC 25922 for 24 hours. Cooperative cultivation active L. with сells at a concentration OD 0.28 after hours (300C) led to decrease up almost 50% coli,...
