Ag/TiO2 photocatalytic nanoparticles by two methods, the sol – gel using a reducing agent and spattering was produced. Crystalline phase of Titanium dioxide was investigated in both. Ag/Tio2 peak in the sol – gel method at temperatures of 300,500 and 6000c were studied. Ag/TiO2 peak at different temperatures were determined using the spattering. XRD p...

Introduction: Soils on Mars have been analyzed by the Mars Exploration Rovers (MER) and most recently by the Mars Science Laboratory (MSL) rover. Chemical analyses from a majority of soil samples suggest that there is a relatively uniform global soil composition across much of the planet [1]. A soil site, Rocknest, was sampled by the MSL science payload including the CheMin X-ray diffractometer...

We performed particle size and particle size distribution measurements for L-cysteine-stabilized ZnS/Mn nanoparticles in the size region below 10 nm. For this we applied transmission electron microscopy (TEM), analytical ultracentrifugation (AUC), dynamic light scattering (DLS), and asymmetric flow field flow fractionation (aF-FFF) measurements, and we calculated particle sizes with the help of...

Low-energy electron diffraction (LEED), atomic force microscopy (AFM), and X-ray diffraction (XRD) have been used to investigate the structural and morphological character of a naturally chiral ceramic SrTiO3(621) substrate and of Pt and Cu thin films deposited on its surface. AFM experiments showed that as-received chirally-oriented SrTiO3(621) substrates display atomically smooth surface morp...

ZnO/SiO2 was prepared using sol-gel method, and vanadium particles were loaded on this nano-photocatalyst by wet incipient method. They characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) analysis andFouriertransform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure and vanadium dope...

X-ray diffraction (XRD) can provide useful information about the composition of an ore sample in terms of quantification of crystalline phases and also amorphous content. XRD is also a powerful technique for studying substitutional solid solutions that can affect mining productivity, such as determining lattice bound aluminum in Goethite. Knowledge of the phases present can predict processing r...

Bhasmas are potent Ayurvedic medicaments, biologically active and powerful healing preparations in all aspects. Properly prepared Bhasmas have not reported any serious untoward effects in clinical practice. Vanga Bhasma is an effective Ayurvedic medicine among various Bhasmas which are classically explained and advised specially in genitourinary disorders. XRD peaks of Vanga Bhasma are identifi...

In this research Calcium fluoride nanoparticles and its different amount of cerium ion dopant (5%and 10%) were prepared. The mentioned nanoparticle were studied by fourier transform infrared spectroscopy (FTIR) , X-ray diffraction (XRD), absorption and photoluminescence spectra (PL) and Scanning electron microscopy (SEM). The XRD patterns indicate a typical cubic fluorite structure and no other...

Abstract: as magnetic materials, semiconductors, pigments, catalysts, refractories and electronic ceramics. In this paper, wereported the preparation of NiAlThe resulting powder was chracterized by XRD, particle size analysis and SEM. The XRD patterns show that thecombustion technique was excellent to prepare single – phased cubic NiAlfound to be around 14 nm. From the particle size analysis, i...
