A new class of silicon drift detectors (SDD), called “VortexTM”, with a large active area (~ 0.5 cm), high-energy resolution (<150 eV FWHM) and high-count rate capability (>1 Mcps) has been developed for X-ray diffraction (XRD) and X-ray fluorescence (XRF) applications. The VortexTM design allows for a relatively large active area while still maintaining a very low anode capacitance (~ 60 fF). ...
The aim of this study was to evaluate the physico-chemical and biocompatibility characteristics of two different hydroxyapatites. Physical and chemical properties were analyzed using granulometric analysis, scanning electron microscopy (SEM), X-ray energy-dispersion (EDX), X-ray fuorescence (XRF) and X-ray diffraction (XRD). Biomaterials were implanted into the subcutaneous tissue on the dorsum...
In this study, silica gel was extracted from rice husk ash using a modified acid-leaching process. The then characterized an X-ray Diffractometer (XRD) and Fluorescence (XRF). At different loadings of 0, 0.05 0.10 wt.%, used as cross-linker in the membrane formulation. Fourier Transform Infrared Spectroscopy (FTIR) Scanning Electron Microscopy (SEM) were to characterize membranes, while their p...
Extraction and Characterization of Fe2O3 from Red Mud PT. Indonesia Chemical Alumina West Kalimantan
Red Mud is a term used for residues or waste materials from bauxite refining. One of the main compositions red mud Fe2O3. This study aims to obtain optimum extraction Fe2O3 conditions hematite by using APDC ligands and knowing characteristics generated. In this study, begins determine pH ligand concentration. The results determining showed 1 concentration 0.5 M. can be resolve through character...
Magnetic data is useful in both hydrocarbon exploration and mining exploration. In hydrocarbon exploration, aeromagnetic data is an effective method for locating strike-slip faulting in magnetic basement. Also, high resolution surveys enhance delineation of both subtle basement features and intrasedimentary sources. In fact, magnetic methods has evolved from its sole use for mapping basement st...

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...
