Homoginization temperature of fluorite [luid indus ian indicate that mineralization has mostly take place within the temperature ranging 70 to 1500C . the last ice melting tcmpenttur ranges from 0 1O·2.2°C and shows that salinity varies from 0 to 3.69 wt% equivalent NaC!. Chemical analysis performed on The liquid phases of fluid indusion show that mineralizing fluids were rich in Ca and ...
Objectives: To prepare Shankha Bhasma, an antiulcer formulation from marine origin and to standardize the by two different methods of preparation compare with marketed modern scientific tools
 Methods: Bhasma was prepared conch shell open closed using adjuvants Kumari Swarasa water subjected characterization conventional method AAS, XRD, EDAX, SEM, TEM, BET, TGA, IR spectroscopy. The effec...
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...
در این کار، نانوذرات ZnO به روش شیمی مرطوب و ZnO دوپه شده با وانادیم به روش مقدماتی تر سنتز شده اند. نانوذرات ZnO در دمای 650 و °C 750 به مدت 3 ساعت کلسینه و سپس به وسیله ,XRD ,SEM EDAX و PL شناسایی شدند. الگوهای XRD نشان می دهند که نانوذرات ZnO دارای ساختار ورتزیت و وانادیم دوپه شده دارای ساختار کریستالی V2O5 هستند. مشحصات ساختاری و خصوصیات فیزیکی این دو نانو ذره بررسی و مقایسه شده اند. دا...
Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...
Magnetic NiFe2O4 nanoparticle (NFNPs) were synthesized by the microwave-assisted method using Tamarindus indica seeds as a green reducing agent’ for better readability. The identification of NFNPs was carried out X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) with energy dispersive analysis (EDX), transmission microscopy (TEM),...
The molecular phylogeny of colpodellids provides a framework for inferences about the earliest stages in apicomplexan evolution and the characteristics of the last common ancestor of apicomplexans and dinoflagellates. We extended this research by presenting phylogenetic analyses of small subunit rRNA gene sequences from Colpodella edax and three unidentified eukaryotes published from molecular ...
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...
