Summary: A novel discrete element method-based approach is proposed for modeling solid state sintering of spherical metallic powder, addressing the thermodynamical mass transport effects and mechanical interaction between particles near grain boundaries. The model consists of solving partial differential equations to describe matter flow behavior at grain boundaries and representing the mechanical interaction using 2-nodal structural elements with 6 degrees of freedom per node. Numerical implementation shows good agreement with experimental data for neck growth and shrinkage rates.

Summary: A dual-periodic structure of CsI(Tl) scintillation screen is proposed to improve the detection efficiency when the structure period reaches the order of microns, with each unit of the primary structure divided equally into four or nine square column-shaped scintillation sub-units to form a secondary structure separated by SiO2 layers. Experimental results show that the performance of the dual-structure CsI(Tl) screen in X-ray imaging outperforms that of a corresponding single-structure screen.

Summary: The effect of SiO2 layer thickness on the light guide and X-ray imaging performance of CsI scintillation screens with micrometer-scale structural period was investigated. The results showed that the spatial resolution of X-ray images using structured CsI scintillation screens with different SiO2 layer thicknesses were close, about 110 lp/mm. However, the X-ray excited optical luminescence and detective quantum efficiency of X-ray imaging varied with the thickness of the SiO2 layer, with an optimal thickness of approximately 350 nm.

Summary: Al-doped beta-Ga2O3 single crystals with high resistivity were obtained through band gap engineering in this study, resulting in the preparation of a high-performance X-ray detector with high sensitivity and fast response speed. The detector demonstrated significantly higher performance compared to commercial amorphous Se X-ray detectors, with a sensitivity 42 times higher and both rise time and decay time less than 0.05 s. The high performance was attributed to the high resistivity and quality of the crystal.
