A novel technique, with which in situ TiB_2 particles and serpentine channels are introduced to prepare wrought aluminum alloy with higher strength, has been successfully applied to produce semi-solid 7075 alloy slurry. The effects of in situ TiB_2 particles and serpentine channels on the microstructure of the 7075 alloy including the grain growth behavior in the semi-solid state of the 7075 alloy were investigated. The experimental results showed that the in situ TiB_2 particles and serpentine channels are beneficial to increase the number of solidification nuclei and to promote uniform distribution of α-Al nuclei. As a result, the semi-solid 7075 alloy slurry with globular-like grains has been successfully produced.

The solid solution crystals, Bi_{4}(Ge_{x}Si_{1-x})_{3}O_{12} (BGSO) with x=0, 0.05, and 0.15, have been grown by the modified vertical Bridgman method. The as-grown crystals show 80% of transmittance with an absorption edge of 285 nm. The relative light yields of BGSO crystals are found to be 7.2%, 6.3%, and 4.2% of CsI(Tl) crystal for x=0, 0.05, and 0.15, respectively. The energy resolutions of these crystals are 18.9%, 21.3%, and 24.7%, respectively, with PMT for 662 keV gamma rays at room temperature when exposed to ^{137}Cs γ -ray. The scintillation performance of BGSO crystals clearly deteriorates with the increase of Ge content. However, the appropriate number of germanium ions doped to BSO crystal can improve its crystallization behavior and effectively restrain component segregation. It is expected that large size crystals of BGSO will be grown and applied to the dual readout calorimeter in the nearest future.
