An in-depth chemical-analytical study has been performed on biscuit and mortar from 17th-18th century tiles from a mediaeval hermitage in the province of Valencia (Spain). Representative samples were chosen from the tile fragments available, using appearance, essentially color and consistency, as the criterion. The chemical composition was analyzed by X-ray fluorescence of the samples in the fo...

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...

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...
