Polyvinyl pyrrolidone capped Zn1-xMnxS (0 ≤ x ≤ 0.1) nanocrystals have been synthesized using wet chemical co-precipitation method. Crystallographic and morphological characterization of the synthesized materials have been done using X-ray diffraction and transmission electron microscope. Crystallographic studies show the zinc blende crystals having average crystallite size approx. 3 nm, which ...

in this scientific research zns nanoparticle was synthesized via precipitation method. two samples were synthesized by this method. the nanoparticle was characterized by xrd techniques, and the size and kind of crystallinity were identified by x-ray diffraction pattern as well. the size measurement has been done by using scherrer's equation. the average sizes of nanoparticles in two sample...

zno and mn-zno nano powders were prepared by the sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and mn-doped zno was obtained 44 and 51 nm, respectively. ...

abstract various studies carried out on different photo anthropometry, but each one had some deficiencies which during the years they have been resolved. the objective of this paper is to test the efficiency of two-dimensional image processing software in photo anthropometry of hand. in this applied research, 204 office workers and industrial workers were selected. their hands were measured by ...

in comparison to the previous researches, zro2 nanoparticles with higher surface area (85 m2/g) have been synthesized in this research. the as-prepared zro2 nanoparticles by co-precipitation method were characterized with x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the surface area of the sample was characterized by bet method. the eff...

A simple, rapid, and sensitive HPLC method was developed and validated to quantify Amphotericin B (AmB) in human plasma. AmB was extracted from spiked plasma by simple protein precipitation with methanol. The separation was performed on an XBridgeTM C18 (150 × 4.6 mm, 3.5 μm) column, with a mobile phase of acetic acid (0.73%) – acetonitrile (60:40, v/v) and at a flow rate of 1 mL/min. The elute...

zno and zro2 photo catalysts were synthesized by sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and zro2 was obtained 44 and 51 nm, respectively. also, photo catalytic degradation of nitro phenol f...

in the current paper,nanostructured nickel oxide (nio) were synthesized by co-precipitation method using nickel(ii) chloride hexahydrate (nicl2.6h2o) and sodium hydroxide (naoh) as starting material. structural, optical and magnetic properties of nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), atomic force microscope (afm), uv–vis absorption; fo...
