Photocatalytic, antibacterial and electrochemical properties of novel rare earth metal oxides-based nanohybrids

Mixed metal oxide nanocomposites (rare earth-based) have become irreplaceable and tend to display great functioning in all kinds of arenas like as photocatalytic, electrochemical, and biological. NiO-CGSO [NiO-Ce0.8Gd0.2O2-??Ce0.8Sm0.2O2-?] nanomaterial was produced by the wet-chemical route for numerous purposes. The development of (FCC) face-centered cubic structure confirmed and there was no derivative phase was observed by XRD. Metal-Oxygen bond was revealed by FTIR analysis. The morphology and elemental composition of the sample were carried out using SEM with EDAX. The optical bandgap of prepared nanocomposite was studied using UV?Vis spectroscopy. Electrochemical behaviour was observed at conditions, voltage (1.3 V), and the frequency (42 Hz?5 kHz). Photocatalytic and antibacterial behavior of prepared NiO-CGSO nanocomposites also investigated. It was found that this novel composite catalyst decomposed 92% of toxic pollutants from wastewater. Further, NiO-CGSO composites showed superior antibacterial performance against aeromonas hydrophila, E. coli, and S. epidermis bacterial pathogens.Scopu

The Fulde–Ferrell–Larkin–Ovchinnikov State in Pnictides

Fe-based superconductors (FeSC) exhibit all the properties of systems that allow the formation of a superconducting phase with oscillating order parameter, called the Fulde--Ferrell--Larkin--Ovchinnikov (FFLO) phase. By the analysis of the Cooper pair susceptibility in two-band FeSC, such systems are shown to support the existence of a FFLO phase, regardless of the exhibited order parameter symmetry. We also show the state with nonzero Cooper pair momentum, in superconducting FeSC with $\sim \cos(k_{x}) \cdot \cos (k_{y})$ symmetry, to be the ground state of the system in a certain parameter range.Comment: 8 pages, 4 figures Journal of Low Temperature Physics, (2013

STUDY OF DIFFERENT TECHNIQUES TO REDUCE MICROBIAL LOAD IN NUTS

Nuts are very nutritive generally used in food and beverages preparation. In modern perspective, the shelf life extension and its quality is important parameter to be taken in consideration for its processing in food industry. Microbiological and chemical studies have been carried on different batches of received raw nuts stored in woven sack bag contained LDPE bag. For reducing microbial load in nuts four method of treatment was chosen. They are autoclave sterilization, Hot air oven pasteurization, Vacuum oven pasteurization, Microwave oven pasteurization. All four methods temperature kept constant and time is varying. In autoclave sterilization there will be nil microbial count and increasing in all physic-chemical parameters. In vacuum oven pasteurization there will be decreasing in microbial load as the time increasing. And all physic-chemical parameters are coming within specification. In hot air oven pasteurization there will be decreasing in microbial load as the time increasing but sensory and physic-chemical properties of almonds got affected. In micro wave oven sensory parameters of nuts got affected as the time increasing there will be development of roasting flavour and texture of nuts became crunchy

Nanostructured metal oxides and its hybrids for photocatalytic and biomedical applications

Metal oxide nanoparticles and its hybrids are deemed to be one of the most attractive materials in an extensive range of applications due to their impressive optical, electronic, photocatalytic, and biological properties. Metal oxide based nanomaterials with extraordinary characteristics have been proposed, prepared, and used as main materials in the recent area of photocatalysis and biomedicine, due to their non-toxic nature, large specific surface area, useful optical bandgap, and high biological activity. Herein, this review reveals the recent advance development in the area like photocatalytic, anticancer and antibacterial performance of metal oxide nanomaterials for multidimensional applications. Consequently, we also focused on the encountered difficulties and prospects for the future application of metal oxide-based composites as promising candidates for the development of highly efficient photocatalytic and biomedical systems. This review article also delivers advanced knowledge to the scientific community who intends to design efficient photocatalytic and biomedical systems.Scopu
