Antibacterial and anticancer properties of NiO nanoparticles by co-precipitation method

Nickel oxide nanoparticles synthesized at room temperature (RT NiO NPs) and 60°C temperature treated nickel oxide nanoparticles (RT60 NiO NPs) were synthesized by the co-precipitation methods. The antibacterial studies performed against set of (gram positive) S.aureus and (gram negative) E. coli bacterial strains showed that the RT60 NiO NPs possessed a greater antibacterial effect as compared to the RT NiO NPs. The cytotoxic effect of the RT NiO and RT60 NiO NPs were examined in cultured (MCF-7) human breast cancer cells

Ultrasonic studies of molecular interactions in binary mixtures of n-Butanol with water at different temperatures (308K, 318K and 328K)

The experimental ultrasonic velocity (u), density (ρ) and viscosity (ƞ) of butanol mixed with water has been measured over the full range of compositions at atmospheric pressure and at different temperatures (308, 318 and 328 K). From these experimental values the molar Isentropic compressibility (βs), Intermolecular free length (Lf), Free volume (Vf) and Acoustic impedance (Z) are calculated

Vibrational spectra and theoretical calculations of thiocynatobi(pipeidinyl dithiocarbamato)antimony(III)

The FTIR and FT-Raman spectra of thiocyanatobi( piperidinyldithiocarbamate) antimony(III) have been recorded in the region4000-400 cm-1. Utilizing the observed FTIR and FT-Raman data, a whole vibrational assignment and analysis of necessary modes of the compounds were carried out. The optimized molecular geometries, vibrational frequencies were calculated by using Hartree-Fock method with HF/3-21G basis set. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecules. Also, several thermodynamic properties, Mullikan’s population analysis, first order hyperpolarizabilitiy, several thermodynamic properties and molecular electrostatic potential were done by the HF method
