TL;DR: In this article, the applicability of direct TXRF analysis of different type of solutions commonly used in environmental and geochemical studies, confirm the absence or presence of matrix effects and evaluate the limits of detection and accuracy for Se determination in the different matrices.

TL;DR: In this paper, the metal distribution in animal bone tissue with inserted bare and coated Co-Cr alloys was evaluated by means of micro X-ray fluorescence mapping, showing that the migration of Co and Cr particles from the bare alloy in the biological tissues is observed just after one month and the number of particles significantly increases after two months.

TL;DR: In this article, a color X-ray camera (CXC) was used to investigate shading effects in full field micro-XRF with small angles of excitation, and the experimentally measured shadings match well with those expected from calculation.

TL;DR: In this paper, an optically read out GEM-based Time Projection Chamber (TPC) is presented, which permits 3D track reconstruction by combining the 2D projections obtained with a CCD camera with timing information from a photomultiplier tube.

TL;DR: In this article, the authors studied the deterioration of various kinds of sandstone due to acid rain and SO2 gas and found that Ca, Mg and Fe leached from the sandstone samples were measured with TXRF.
