Oil palm ash (OPA), a bio-agricultural waste from oil palm mills, was subjected to high-energy ball milling for 30 h and was converted into a nano-structured material. The nano-structured OPA was characterized for its particle size and crystallinity index by using Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) analysis. The crystallite size obtained from TEM and XRD was foun...

Cadmium oxide (CdO) nanoparticles have been prepared by chemical coprecipitation method. The synthesized nanoparticles were characterized by X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV analysis, and dielectric studies. The crystalline nature and particle size of the CdO nanoparticles were characterized by Powder X-ray diffract...

Yeast extract powder (YE powder) is particularly used in culture media for the cultivation of microorganisms found in milk or other dairy products. The present study was intended to explore the influence of biofield energy treatment on the physicochemical and spectral properties of YE powder. The study was accomplished in two groups; first group was remained as control, while another was subjec...

We measured 23 Na-NMR spectra and nuclear spin-lattice relaxation rates 23 (1/T1) of superconducting and non-superconducting bilayer hydrate NaxCoO2 · yH2O (x ∼ 0.3, y ∼ 1.3). The central resonance frequency shows a small but various shift due to the difference in the shielding effect by intercalated H2O molecules. The different shielding effect also gives a large difference in the magnitude of...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...

Certification of the phase compositions of the three NIST Reference Clinkers will be based upon more than one independent method. The current reference values were established using an optical microscope examination, with additional optical microscope data taken from an ASTM C 1356 round robin. The present X-ray powder diffraction (XRD) study provides the second, independent estimate of the pha...

Amorphous and crystalline powder of PLT phase was synthesized by using the Pechini method. Infrared (FTIR) analysis of the polymeric resin shows intense bands of organic materials from 250 to 1620 cm−1. X-ray diffraction (XRD) and Raman spectra of calcined powder at different temperatures show amorphous phase at 450 ◦C/3 h, semi-crystalline phase at 550 ◦C/3 h and a crystalline phase at 800 ◦C/...
