WebThe crystallochemical analysis was performed using the X-ray powder diffraction method. The Bruker-AXS D8 Advance diffractometer (Karlsruhe, Germany) was used to collect diffractograms. Results: The tested materials showed a close resemblance in chemical composition and a considerable differentiation in cytotoxic response. WebWe present the stepwise computer screening results to identify solids prone to Zn2+-ion conductivity. The rapid geometrical–topological (GT) screening based on Voronoi partition was utilized as the first step for high-throughput analysis of the ICSD. We found that 334 of 782 Zn-/O-containing compounds possess one-dimensional (1D)-, two-dimensional (2D) …
