Fish scales of the Arapaima gigas (pirarucu) species were heat-treated to obtain natural hydroxyapatite (HAp), and it was doped with niobium (Nb) by physical ultrasound interference confirm an effective route production Nb-doped HAp powders. The effect application on doping investigated. structure powders elucidated using X-ray diffractometry (XRD), scanning electron microscopy, IR spectroscopy...

In this study, magnetic sand and Crotalaria pallida gotten from Adamawa Bauchi states of Nigeria, respectively, were mixed after treatment, impregnated with kaolin using a wet impregnation method the resulting material was characterized scanning electron microcopy (SEM), X-ray fluorescence (XRF) diffraction (XRD). The result XRF analysis revealed existence number dopant-like constituents in sam...

صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...

A non-invasive XRD-XRF portable system for Archaeometry based on Angle and Energy Dispersive XRD (Hybrid XRD) plus XRF has been previously proposed by the authors. It gathers an attractive compromise between analytical performance measurement time, as well a higher energy penetration with respect to conventional (ADXRD). Penetration inside layers, usually perceived inconvenient or analyzer, can...
