Silver nanoparticles have a wide range of anti-bacterial, anti-fungal, and anti-viral effects due to their unique properties. In this work, citrate reduction has been employed to fabricate silver colloidal nanoparticles with 12 nm. The plasmon resonance spectra of nanoscopic silver particles adsorbed onto transparent electrodes in contact with various electrolyte solutions and concentrations of NaC1O4, KPF6, and NaCl were studied. Potentials were controlled with a galvanostat, and UV/visible spectrophotometer was employed to obtain the optical spectra. The results showed the electrolyte identity, potential-induced redshifts, and damping is most pronounced for NaCl, whereas spectral changes are weaker in the cases of NaC1O4 and KPF6 solutions. Hence, due to the noble physical and biological properties of silver colloid nanoparticles, it becomes a great candidate and promising in the future to be used as an anti-coronavirus surface.

Water is one of the essential primary resources for life and development on the planet, where many industrial activities depend on it, but some industries lead to water pollution. Hence, we need economical and effective ways to address the contamination. This article describes the production and utilization of MgO nanopowder using thermal decomposition as an economical and efficient method for malachite green decolorization. The MgO nanopowder was analyzed via various techniques for morphology, cryptography, surface area, etc. Batch adsorption tests have been performed as a function of contact time, pH, and initial dye concentration to study their impact on decolorization of malachite green via MgO nanopowder. The result verified the target nanopowder's production with crystallite size 20.16 nm and a relative surface area of 19.84 m2 /g. MgO nanopowder was employed to decolorize malachite green dye in an aquatic solution utilizing a batch method. The findings revealed that the maximum adsorption capacity value was 232.26 mg/g. The adsorption was found to follow the Freundlich isotherm models and follow the pseudo-second-order kinetics

Metal oxide nanocomposites have concerned an obvious agreement of consideration because of their enormous applications in numerous domains like photocatalyst, catalysis, biological and sensors. The conservational purification technology is getting advanced by the development of heterostructured semiconductor photocatalysts. In this paper, we documented a comparative analysis of synthesis process (Solution-based methods, High temperature-based methods and Electrical methods) and characterisation techniques such as Transmission electron microscopy, X-ray diffraction, Fourier-transform infrared spectroscopy and Scanning electron microscopy on various noble Nanocomposites (NCs) of metal (M) - zinc oxide (ZnO/ZO). This review inclines over multiple stat-of-the-art applications like photocatalytic, catalyst, sensor and biological activities. It could be concluded from this study that, the catalytic activity of noble M-ZO nanostructures depends not only on the noble metal species, but on the catalytic material architecture as well. The future research and development challenges together with future prospects are critically presented.

In this report, a facile, low-cost, and effective method has been employed to produce highly monodisperse colloids photonic materials ZnS QDs/SiO2 were fabricated using chemical condensation reactions on poly-methyl methacrylate. The obtained results exhibit whispering gallery emission modes with 1.47nm spacing. In addition, the emission from ZnS QDs was modulated by a spherical microcavity. Furthermore, the spherical cavity dimension was calculated using the relation between modes spacing and cavity dimension and found to be 11.86 m.

Pyrolysis of sweet sorghum, lignocellulosic graminaceous plant has been conceded using the fixed bed tubular reactor. Temperature plus catalyst are the important factors which effect the pyrolysis process. Here catalytic pyrolysis has been done by the catalyst ZnO-Fe2O3/Al2O3 at different temperatures. We have done our pyrolysis reactions on3changed temperatures i.e. 250̊ C, 350 ̊C, 450 ̊C. By using catalyst, we obtain the pyrolytic products at a very low temperature and it is proved very efficient method for biofuel production. From different temperature experimentation, we concluded that the best optimal temperature along with catalyst for pyrolysis is 350 ̊C for the yield of bio oil. Maximum yield can be obtained at this temperature.

The eggshell cuticle is the proteinaceous outermost layer of the eggshell which regulates water exchange and protects against entry of micro-organisms. Outer eggshell and cuticle protein was extracted from domestic chicken. The aim of the research is to find out the effect of the treated and untreated nano particles of egg shells with micro wave cold plasma on the effectiveness of E. coli (negative bacteria) that infect the skin and measure the diameter of bacterial inhibition zone, the eggshell has been prepared by a chemical method (sol gel) and measure the level of acidity and the PH is neutral. The result of Atomic Force Microscope (AFM) shows that the particles diameters become smaller with nano-particles solution than for egg shell tests (powder). The nano-particles solution for egg shell exposed to cold plasma. The microwave plasma used in this search has voltage "175v" and the gas flow at " 5liter /min " and frequency (2.45 GHz) at the room temperature for five minutes’ time.

The application of nanotechnology in the textile finishing is increasingly being explored due to its unique and valuable characteristics. This has brought up many innovative finishes as well as new application techniques. The nano-finished textile materials are found to have better physical properties than the conventionally finished textiles, in areas such as anti-microbial properties, UV blocking, soil-resistance, etc. In the present work, zinc oxide nano-particles were prepared by wet chemical method using zinc nitrate and sodium hydroxide as precursors and solublized starch as stabilizing agent. These nanoparticles were impregnated onto cotton fabrics by pad-dry-cure method using acrylic binder. A fine medium weight cotton fabric samples were used for this. The aims are to impart anti-microbial functions to the textile substrate and the functional properties of coated fabrics. The nano-ZnO impregnated cotton fabrics showed excellent antimicrobial activity against two types of representative bacteria viz. gram-positive organism (S.aureus) and gram-negative organism.

Plant-mediated synthesis of ZnO nanoparticles (ZnONPs) is preferable than the conventional methods with many applications in medicine and biology. Artemisia annua is recognized to have antiplasmodial, antimicrobial activities, so the nanoformulation based on its extracts and zinc oxide would be of therapeutic benefit. This study aims to investigate properties of ZnONPs based on Artemisia annua leaves and stems extracts and zinc acetate. Spectroscopy techniques, XRD, SEM and Energy Dispersive X-ray Spectroscopy (EDS) were used to investigate the structural and optical properties of the ZnONPs. The characteristic absorption peak was at 375.5 nm and the excitation at 365 nm showed wide spectra in visible (450-700 nm). XRD, SEM and EDS analysis confirmed a pure ZnONPs in wurtzite hexagonal structure with a size of 21.34 - 24.71 nm. These nanoformulations would be multifunctional and are candidate for treatment of malaria, cosmetics and optoelectronic.

In this study we have designed six metal free D–π–A system and evaluated their optimum properties for Dye sensitized solar cell (DSSC). The ground state geometries, electronic properties, light harvesting efficiency, and electronic absorption spectra of these dyes were studied using Density functional theory and Time dependant density functional theory. All these calculations were performed in the gas phase and Dimethylformamide, Dichloromethane as solvent. Our theoretical calculation reveals that the designed metal free organic dyes are good candidate for DSSC applications.
