Abstract:
A purification method that uses ion-selective ceramics to electrochemically filter waste products from a molten salt. The electrochemical method uses ion-conducting ceramics that are selective for the molten salt cations desired in the final purified melt, and selective against any contaminant ions. The method can be integrated into a slightly modified version of the electrochemical framework currently used in pyroprocessing of nuclear wastes.

Provided is a scintillator used for radiation detection in an X-ray CT scanner or the like, the scintillator having a unidirectional phase separation structure having an optical waveguide function, which eliminates the need of formation of banks for preventing crosstalk. The scintillator has a waveguide function instead of the banks or the like. The scintillator includes: a first crystal phase including multiple columnar crystals having unidirectionality; and a second crystal phase for covering a side of the first crystal phase. The first crystal phase includes a perovskite type oxide material including at least one element selected from the group consisting of Lu and Gd, and a rare earth element as an emission center.

The laminated composite includes at least one wavelength-converting layer and at least one non-emissive layer, wherein a vertical relief gap pattern defines the composite into a plurality of discrete separable portions, and the discrete separable portions are breakably joined by a non-emissive layer. Separation along the relief gap pattern reduces color variation amongst the discrete portions and processes.
Abstract:
Embodiments disclosed herein include methods of modifying synthetic garnets used in RF applications to reduce or eliminate Yttrium or other rare earth metals in the garnets without adversely affecting the magnetic properties of the material. Some embodiments include substituting Bismuth for some of the Yttrium on the dodecahedral sites and introducing one or more high valency ions to the octahedral and tetrahedral sites. Calcium may also be added to the dodecahedral sites for valency compensation induced by the high valency ions, which could effectively displace all or most of the Yttrium (Y) in microwave device garnets. The modified synthetic garnets with substituted Yttrium (Y) can be used in various microwave magnetic devices such as circulators, isolators and resonators.
