Zuotai (gTso thal) is one of the famous drugs containing mercury in Tibetan medicine. However, little is known about the chemical substance basis of its pharmacodynamics and the intrinsic link of different samples sources so far. Given this, energy dispersive spectrometry of X-ray (EDX), scanning electron microscopy (SEM), atomic force microscopy (AFM), and powder X-ray diffraction (XRD) were u...

MINERALOGICAL and physical characteristics of natural chromites from Oman ophiolites have been recently investigated using M6ssbauer spectrocopy (MS), X-ray diffraction (XRD) and Scanning electron microscopy (SEM) by Al-Alawi et al. (1996). From the MS analysis together with the SEM data, they derived the chemical formula for specimens collected from two separate chromite deposits named Tawiyah...

Dihydroquercetin is a kind of dihydroflavonol compounds with antioxidant, antitumor, antivirus and radioresistance activities. This study attempted to produce the dihydroquercetin complexes with lecithin and β-cyclodextrin, and research their characteristics and bioactivities via ultraviolet spectrum (UV), infrared spectroscopy (IR), scanning electron microscope (SEM), differential scanning cal...

Metal oxides play significant role in many fields of nanotechnology including nanocatalysis, sensing, supermagnetic properties, fuel cells, nanoenergy storage and conservation. Dyes are synthetic compounds which have wide range of application in textiles, paints etc., and the dye effluents from the dyeing industries cause water pollution. In this present study, ZnO photocatalyst have been synth...

Physical, mechanical, and morphological properties of a clay dispersed styrene-co-glycidal methacrylate (ST-co-GMA) impregnated wood polymer nanocomposite (WPNC) were evaluated. The WPNC was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), 3-point bending, free-vibration testing, and Xray diffraction (XRD) measurements. The FT-IR results showe...

The reaction of Nevada opal with calcium hydroxide, potassium and lithium hydroxide solutions was investigated. In addition opal was exposed to a combined solution of these three hydroxides. The progress of the three reactions was followed using X-ray Diffraction (XRD), 29 Si Nuclear Magnetic Resonance (NMR) and Scanning Electron Microscopy (SEM). The XRD results indicated the presence of a low...

The effect of fluorine addition on morphological, structural and electrical properties of superconducting samples of composition Y3Ba5Cu8Oy-xFx (x = 0.0, 0.2, 0.4 & 0.6) were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transition temperature (Tc) measurements. The samples were synthesized by solid state reaction method. The XRD of the samples revealed a struc...
