Enhancement of XRF intensity was investigated by using an Au coated glass-capillary. Au was electroplated on an inner wall of the glass-capillary with a thickness of 100 nm. The Au coated glass-capillary was attached to a micro focus x-ray tube. The XRF intensity from the pure metal samples was measured by a silicon drift x-ray detector. It was confirmed that the intensity of XRF was enhanced b...

We report the discovery of optical and radio afterglow emission from the extremely soft X-ray flash, XRF 020903. Our spectroscopic observations provide the first redshift for an X-ray flash, thereby setting the distance scale for these events. At z = 0.251, XRF 020903 is one of the nearest cosmic explosions ever detected, second only to the recent GRB 030329 and the unusual GRB 980425/SN 1998bw...

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...

X-ray fluorescence (XRF) spectroscopy was measured on duplicate libraries deposited on Si (without BiVO4) due to the overlap between the Ce Lα line (4.839 kV) from the coating and the V Kα line (4.952 kV) from the BiVO4. The x-ray beam was approximately 2 mm in diameter. Since the XRF sampling depth far exceeds the film thickness, XRF counts for each element were assumed to be proportional to t...
