Natural fiber composite (NFCs) are gaining importance in various fields of engineering due to their eco-friendly nature and low cost. The aim of this present work was to evaluate the influence of basalt fiber and variation of rice husk powder (10%, 15%, and 20%) on the impact strength and hardness of basalt fiber epoxy polymer composites. By using the compression molding method the compositions were prepared by varying the proportion of rice husk powder. Filler was used to modify the epoxy composite: basalt fiber (BF), epoxy composite, and Rice Husk Particle (RHP). After the materials are subjected to hardness by Rockwell hardness method and impact strength by Charpy method. The results of the conducted research confirm that the addition of a rice husk particle to the basalt fiber reinforced with epoxy polymer composites is an effective method of improving their hardness and impact characteristics.

Silver nanoparticles are well known powerful antimicrobial agents. Despite significant advances in clarifying the antimicrobial mechanism of silver nanoparticles, the exact mechanism of action is not yet fully known. Previous reviews for Of silver nanoparticles Advances in research on antimicrobial mechanisms and recent original contributions are included in this overview. Topics discussed include antibacterial and anti-silver ion interactions against silver nanoparticles. At the center of the overlay is a summary of current knowledge about Antibacterial activity of silver nanoparticles. The possibility of pathogenic microorganisms developing resistance to silver nanoparticles is also discussed. Silver nanoparticles (Ag-NPs) change rapidly in the environment, changing their properties and changing their transport, fate and toxicity. Such changes should be considered when assessing the potential environmental impact of Ag-NPs. This review looks at different aquatic environments Discusses the important transformation processes of Ag-NPs, Especially organic ligaments and physical and chemical stability and Changes in metal Ag cores caused by the effects of such changes in toxicity. Predict what the shapes of oxidized silver are Thermodynamic arguments are used will look like under different environmental conditions

The advantage of using plants in nanoparticles synthesis is that they are easily available, safe to handle and possess a broad variability of metabolites such as antioxidants, nucleotides and vitamins. The aim of this study was to investigate the effects of Green and Zimbro tea and also Green coconut water as a reducing and stabilizer agent in gold nanoparticle synthesis. The gold nanoparticles were characterized by UV-Vis absorption spectroscopy, X-ray diffraction (XRD), Dynamic light scattering (DLS) and Transmission electron microscopy (TEM) analysis. Their physical stability was determined using a UVVis spectrophotometer over several days during storage at room temperature. We observed that green chemical process to obtain gold nanoparticles did not require any external chemicals reagent for stabilization of nanoparticulate. Absorption measurements indicated that the plasmon resonance wavelength appears around 530 nm. X-ray diffractograms of gold nanoparticles evidenced the presence of Au-rich (fcc) phases. TEM analysis showed a homogeneous dispersion of nanoparticles and some agglomerates. Differences in size and shape of the nanoparticles were observed. Zeta potential of AuNPs synthetized in presence of Green tea was −33 mV indicating stability of the synthesized nanoparticles.
