γ-ray self-absorption of cylindrical fissile material

The self-absorption of γ-ray emitted from cylindrical fissile materials, such as ^235U and ^239Pu. does not possess spherical symmetry. The analytical formulae of self-absorption for y-ray throughout the cylinder have been obtained. The intensity of γ-ray is a function of y-ray outgoing directions and cylindrical configorations, accordingly one can acquire the information about geometrical configuration of cylindrical fissile materials through multi-location measurements. Further more. the method is given in this article, The result can be applied to the fissile material safeguard, such as nuclear monitoring and verifying.

Pressure infiltration of Al and Al-12 wt% Si alloy into compacts of SiC and oxidized SiC particles

Oxidizing SiC particles is a common practice in the fabrication of SiC/Al composites through direct mixing of the liquid metal and the ceramic particles. This practice is addressed to reduce the reaction between the two materials. In a previous work it was concluded that oxidizing SiC particles scarcely affected the threshold pressure for infiltration of pure Al into compacts made of those particles. In this work we present a detailed study of this problem for infiltration of pure Al and the eutectic Al-Si alloy. Our results indicate that oxidizing of SiC particles does not affect significantly either the threshold pressure or the infiltration kinetics. This conclusion is equally valid for both pure Al and the eutectic alloy.     

Application of N-succinimidyl 4-[(18)~F](fluoromethyl) benzoate to protein labeling

N-succinimidyl 4-[18F](fluoromethyl) benzoate for protein labeling was prepared (57%, EOB) in about 30min. Reaction conditions of S18FMB with IgG including pH of solutions, protein concentration, reaction temperature and time were studied. The optimal labeling conditions were: 0.2mg/mL IgG, pH = 7.8-8.5, 25℃, and reaction time 5min.Under these conditions the yield was about 80%. The 18F-labeled protein was purified by size exclusion chromatography.
