Direct Measurement of Hydrogen Diffusivity and Solubility Limits in Zircaloy 2 (Formula Unit of ZrH 0.0155 ) using Incoherent Quasi-Elastic Neutron Scattering

May 1, 2019
Author(s)
Brent J. Heuser, Timothy R Prisk, Jun-li Lin, Tanya J. Dax, Yongfeng Zhang
The diffusivity of hydrogen is an important property of light water nuclear reactor (LWR) fuel cladding. LWR cladding absorbs hydrogen during normal operation, a contributing factor to embrittlement that decreases the lifetime of the fuel. Mass transport

Matrix Clusters and Polymer-Matrix Adducts in the MALDI Analysis of Polystyrene

January 1, 2000
Author(s)
R J. Goldschmidt, Charles M. Guttman
The formation of matrix cluster ions and of polymer-matrix adduct ions in the matrix-assisted laser desorption/ionization (MALDI) analysis of polystyrene was investigated using layered sample preparations. It has been shown by post-source decay (PSD)
