Solid state reactions of potassium or sodium with tin and arsenic resulted in the formation of a new ternary Zintl phase, K2SnAs2 (1) and a new modification of the binary Zintl phase NaAs (2), the syntheses and structures we report herein. Compound 1 is described in the orthorhombic space group Cccm with the unit cell dimensions a = 14.653(5), b = 25.415(6), c = 6.953(4) Å, V = 2589(2) Å3 at 203 K,...
Radioscopy and computed tomography in medical applications are well established and have reached a high level of development. Compared to medical applications industrial nondestructive-testing (NDT) has to deal with a large variety of different materials and material combinations, densities and density dynamics, geometries and structures which need to be inspected. This large variation necessitates...
Micro-CT with resolutions in the order of 1 μm is readily available nowadays but below 1 μm the maximum achievable resolution is not only limited by the components parameters like pixel size and focal spot size but also depends strongly on the stability of the whole CT system. We present the performance of our Sub-μm CT based on commercially available components and will show that it is possible to...
