The method of synthesis of Atomoxetine is developed, including enzyme-catalyzed stereospecific reduction 3-chloro-1-phenyl-propan-1-one and Mitsunobu condensation with a chiral alcohol, and o-cresol. New potential human carbonic anhydrase inhibitors were obtained via reaction Atomoxetine with carboxylic derivatives of benzene and thiophene containing primary sulfonamide moiety.

The present paper explains the synthesis of super porous hydrogel (SPH) with reinforcement of different concentrations (0.05, 0.1, 0.15 and 0.2 g) of PVA by solution polymerization. The polymerisation process is conducted at a pH value of 5. The corollaries of PVA on different characteristics of super porous hydrogel were studied. The characterization study involves measurement of apparent density, swelling, mechanical strength and microstructure. The PVA added SPH are treated for a total time of 550 minutes in double distilled water and acid salt solution to analyse the swelling properties. The result shows that inclusion of PVA to SPH reduces its swelling tendency culminating that; the empathy for swelling is more in double distilled water than acid medium.

The use of modified multiwall carbon nanotubes (MWCNTs) for high concentration of ferric iron removal from acid mine drainage was studied. Fourier transform infrared spectrum demonstrated that hydroxyl and carbonyl functional groups were introduced to the surface of MWCNTs after oxidation with nitric acid. The adsorption behavior of modified MWCNTs was then investigated in removing 50-200 mg/L Fe(III) through batch and continuous flow fixed bed experiments. Batch experiment results demonstrated that the Fe(III) adsorption capability of MWCNTs after oxidation had increased by 32%. Adsorption equilibrium was achieved during the first 90 min. Langmuir model can be successfully employed for the equilibrium of isotherms with R2=0.9878 and qmax=89.05 mg/g. In addition, the effect of column bed depths and the influent Fe(III) concentrations were studied through the continuous fixed-bed adsorption studies. Results indicated that Fe(III) uptake favoured particularly higher bed depth and lower influent concentration. The bed uptake capacity of Fe(III) was found to be in a range of 30.30-41.51 mg/g, which was much lower than in batch experiment.

Maesobatrya barteri root extract inhibited the corrosion of aluminium in hydrochloric acid solutions by both gravimetric and thermometric methods. The inhibition efficiency increased with increase in root extract concentration but decreased with increase in temperature. The adsorption of the root extract on aluminium surface obeyed the Langmuir adsorption isotherm. The calculated thermodynamic parameters revealed that the corrosion inhibition process was both endothermic and spontaneous. Physical adsorption has been proposed for the adsorption of Maesobatrya barteri root extract on aluminium surface.

By using X-ray powder diffraction and differential thermal analyses, scanning electron microscopy technique and microhardness measurements the phase equilibria in the Tl9TbTe6-Tl9BiTe6 system were investigated. According to the obtained experimental results the T-x diagram and concentration dependence of the cell parameters and microhardness of alloys of the Tl9TbTe6-Tl9BiTe6 system were constructed. It is shown that the system is not quasi-binary due to the peritectic melting of Tl9TbTe6, but stable below the solidus. In the system, it is found to be continuous solid solutions with Tl5Te3 structure. These phases may be of interest to thermoelectric and magnetic materials.

A new series of complexes containing Triazene compound was prepared, Triazene compound was prepared by the diazotization of o-toluidine then reacting with piperidine to give the corresponding triazene compound (1-(o-tolyldiazenyl)piperidine). The complexes M[(2-CH3-C6H3-N=N)-N-C5H10)] 2X2- of Cu(II), Ni(II), Co(II), Zn(II) and Fe(II) with triazene compound (1-(o-tolyldiazenyl)piperidine) has been synthesized by the reacting between copper bromide, hydrate nickel chloride, hydrate cobalt chloride, zinc chloride, and iron bromide in 1:2 mole ratio. It has been isolated in the solid state and characterized by (C.H.N) data, IR and 1H NMR spectroscopy. Six coordinate and octahedral complexes were producted and the results are reported and discussed below.
