ZnS nanoparticles have been synthesized using various amounts of aqueous Azadirachta Indica (Neem) leaf extract as capping agent and stabilizer. The synthesized nanoparticles were studied by FTIR, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive analysis of X-rays (EDAX) and UV-Visible spectroscopy. FTIR spect...

Selenium nanomaterials (Nano-Se) are new selenium sources with excellent biocompatibility, degradability, and bioactivities. The objective of the present study is green synthesis nanoparticles (SeNPs) using Diospyros montana Roxb (DM) bark extract, its characterization, evaluation for in-vitro antioxidant, antibacterial anticancer activities. To synthesize montana- (DM-SeNPs), selenious acid (H...

a r t i c l e i n f o Keywords: Diamond Raman spectroscopy EDAX Inclusion Platinum group element Kimberlite Five natural faceted diamond samples, considered to have inherent submicroscopic and nanometric inclusions, were studied using various techniques such as Raman spectroscopy, Raman microscopy, scanning electron microscopy (SEM), and energy dispersive analysis of X-rays (EDAX). The principa...

This present work is aimed to optimize the machining parameters and study effect of powder mixed dielectric fluid on EDM process. TOPSIS method optimization adopted identify optimal parameters. HCHCr die steel preferred as material. Ni, Zr Ni+Zr were selected inclusion in due hard ductile nature. L9 array Taguchi DOE perform experiments with like peak off time, pulse time current. revealed that...

Abstract Silver/Zinc Oxide nanocomposites (Ag-ZnO NCs) were fabricated by varying the weight percentages of both Ag and ZnO for investigating its photocatalytic activity. The structural, morphology optical response prepared examined with PXRD, FESEM, TEM, EDAX, XPS, FT-IR, UV–vis-DRS PL spectroscopy. effect concentrations on these was examinedby analyzing thephotocatalytic activity towards Meth...

The effect of Lawsonia inermis Linn Leaf extract on electroless deposition Zinc-P alloy mild steel is studied in alkaline solutions. experimental processing parameters the rate investigated during plating. bath compositions and operating conditions are optimized. results obtained show inclusion Zn-P coating found to be increased by increasing volume additives from 0.5ml 1.5ml. Structured UV - A...

Abstract The friction and wear reducing properties of ammonium thiomolybdate as a water‐soluble lubricant additive were evaluated using pin‐on‐disck tribometer on steel‐steel contact. tribological performance aqueous solutions prepared at concentrations between 0.1 0.3 wt% Mo the same load (10 N), entrainment speed, sliding distance temperature. Although there is reduction compared with pure wa...

Ceramic findings from “Grotta dei Cocci” and dating back to the Early Neolithic were studied. The ceramic samples have been characterized by a combined use of Optical Microscopy (OM), X-ray Powder Diffraction (XRPD) Scanning Electron (SEM-EDAX) define mineralogical assemblage, estimate firing conditions provide information on raw materials used for production. results show that main mineral inc...

Abstract The present study focuses on the Preparation of Aluminum Oxide, and Copper oxide antifouling coatings to prevent or reduce corrosion fouling in ships marine vehicles. Al 2 O 3 CuO nanoparticles were prepared using ball milling process. nano paints these as pigment linseed alkyd resin a binder. Mild-steel specimens coated with paint immersed seawater for 120 days properties studied Scan...
