Phase Equilibria and Crystallography of Ceramic Oxides
Two fused-quartz slides coated with evaporated gold are held in a parallel geometry by a clamp. The spacing between the slides is established by a thickness of gold filler sheets. An aluminum crucible filled with zirconia powder was used to apply the load to the standing crystal (grown from an Ba-Y-Cu-O melt in a gold crucible) on the edge (with the c -axis in the plane of the slide).

Radiolysis of Macromolecular Organic Material in …
As a result, nontronite is potentially a more effective semiconductor surface than fused silica that yields increased radicals relative to fused silica (Thomas, 2005). It is not possible to determine which mechanism, either Fenton reactions or irradiation of semiconductor surfaces, is primarily responsible for organic acid production in synthetic analog samples from this data set.
