    ABSTRACT: The purpose of this study was to investigatethe potential toxicity of silver nanoparticles tofecalbacteria, on the example of Lactobacillus , Bifidobacterium and Peptostreptococcus isolated from infant’s feces on the first an d the second day of their life. Bacteria was treated nano-silver solutions and their dilutions with approximate concentration of silver 2 μg ml -1 , 0,25 μg ml -1 and 0,05 μg ml -1 purchased from three different producers. Antibacterial activity of silver nanoparticles was tested using the disc-diffusion method and dilution method. Concentration of silver nanoparticles at level 2 μg ml -1 (150nm) had the best and statistically different antibacterial activity to the tested lactic acid bacteria. Nanoparticles of the same concentration (0,05 μg ml -1 ) and size (80-150) had similar antibacterial properties. In disc-diffusion method opposite to dilution method, the least susceptible bacteria for nanoparticles was Peptostreptococcus . The obtained results depended on used method and important limit for disc-diffusion method was observed.

    ABSTRACT: The properties of hard magnetic Ferrous Tungsten Phosphorous (Fe-W-P) films electrodeposited in the presence of urea as additive and phosphorous as precursor with varying concentrations were studied for different current densities in order to get different thickness and uniform deposits. The magnetic saturation (Ms), retentivity (Mr) and coercivity (Hc) of the films were studied using vibrating sample magnetometer. Magnetic properties of the deposited films were increased with the increase of organic additive and phosphorous. The crystallite size and stress of the deposited thin films were calculated using X-ray diffraction (XRD) studies. Percentages of elemental analysis of Fe-W-P films were obtained using energy dispersive X-ray analysis (EDAX). Surface morphology analysis was carried using scanning electron microscope (SEM). The magnetic properties and structural characteristics of the thin films deposited under various experimental conditions are discussed. Hardness and adhesion of the deposited thin films were also studied.

    ABSTRACT: Green nanotechnology is generating attention of researchers toward ecofriendly biosynthesis of nanoparticles. In this study, the possible role of nutmeg extract in reducing silver nitrate into silver nanoparticle is highlighted. These biosynthesized nanoparticles were characterized with the help of UV-visible spectrophotometer, atomic absorption spectroscopy, X-ray diffraction, fourier transform infrared spectroscopy and transmission electron microscopy. It was observed that Myristica fragrans seed extract can reduce silver ions into silver nanoparticles within 12 min of reaction time. The surface plasmon resonance peak, centered near 410 nm, affirmed the reduction of Ag+ to Ag0 . Stability of synthesized silver nanoparticles was analyzed using UV-visible absorption spectra. Transmission electron microscopy images show the presence of silver nanoparticles in the size range 7–20 nm. These biosynthesized silver nanoparticles were found to be stable for 3 months. Rapid and ecofriendly biosynthesis of stable silver nanoparticles was observed in this study. The crystalline nature of these biosynthesized silver nanoparticles was analyzed by X-ray diffraction studies. With the help of fourier transform infrared spectroscopy analysis the possible role of proteins and phenols as a reducing and capping agent was inferred. These silver nanoparticles synthesized from biological route also showed promising antibacterial effects against test microorganisms.
