The clinical challenge in the reconstruction of bone defects has stimulated several studies in search of alternatives to repair these defects. The ceramics are considered as synthetic scaffolds and are used in dentistry and orthopedics. This study aimed to evaluate by micro energy-dispersive X-ray fl uorescence spectrometry (μ-EDXRF) and scanning electron microscopy-energy dispersive spectrosco...

In this work the performance of a screening analytical method for Energy Dispersive X-Ray Fluorescence (EDXRF) analysis in terms accuracy and precision was evaluated through rock standard reference materials. The allowed division elements into four groups taking account excitation energies measurement conditions sample. Two materials were used 15 sample replicates prepared analyzed, then statis...

Abstract Purpose Information about particle size distribution (PSD) and soil texture is essential for understanding drainage, porosity, nutrient availability, trafficability. The sieve-pipette/gravimetric method traditionally used analysis labour-intensive resource-intensive. X-ray fluorescence (XRF) spectrometry may provide a rapid alternative. study’s aim was to examine the use of XRF determi...

Abstract Background and aims This study explores the use of energy dispersive x-ray fluorescence (EDXRF) for screening micronutrient concentrations in lentil sorghum grain biofortification breeding programs. Methods Lentil seed was provided from programs analysed with inductively coupled plasma mass spectrometry (ICP-MS) to determine reference concentration levels Ca, Mn, Fe, Cu Zn. A subset th...

Polyester based particle reinforced composites were developed using varying weight fractions (ranging from 0 to 30 wt%, at 5 wt% interval) of microcrystalline wood charcoal powder (75µm). Quantitative, qualitative and functional characterization (WC) particles polyester matrix was carried out successfully energy dispersive x-ray spectrophotometer (EDXRF), Fourier transform infrared spectrometer...

Sulfur is a low-toxicity element in its elemental form, but when combusts with air becomes sulfur dioxide, an irritating and toxic compound. This compound is released from many combustion processes because of the fact that different fuels such as coal, petroleum, diesel or natural gas contain certain amounts of sulfur. Therefore, nowadays there is a clear need to develop analytical methodologie...

Corundum primary deposits in Greece occur four locations: Paranesti Drama and Gorgona Xanthi, both belonging to the wider Rhodope Massif, as well as, Ikaria island Kinidaros Naxos island, Attic-Cycladic Massif. Eight samples were examined with spectroscopic methods (FTIR, UV-Vis, EDXRF) order better characterize these deposits: two pink sapphires from Paranesti, a blue sapphire Gorgona, three K...

In this work, we studied the features of a modern Chinese cloisonné vase by means small-spot energy dispersive X-ray fluorescence (EDXRF) and micro-Raman spectroscopy. Quantitative elemental results enamel have been obtained after calibration EDXRF instrumentation with certified reference materials. Up to eleven different coloured enamels recognized analysed (black, pink, red, white, yellow thr...

A method has been developed for direct non-destructive energy dispersive X-ray fluorescence (EDXRF) determination of sulfur in solid uranium ores and intermediates, obtained from the alkaline recovery process its ores. The involves thorough grinding a few mg powder samples to fine particle size mixing thus with drops 10% collodion solution amyl acetate make paste. very small amount this paste w...
