We review the recent SAXS activity on the 1.5-GeV electron storage ring at the National Synchrotron Radiation Research Center (NSRRC). Typical measurements featuring in grazing incident SAXS for soft materials are illustrated. Complex measurements using simultaneous SAXS/DSC and SAXS/WAXS for the correlations between the crystallization and mesoscale ordering in a polymer blend and a polypeptide-block-polypseudorotaxane diblock copolymer are presented. We also introduce a dedicated SAXS beamline which is planned at NSRRC.
The soldering process is an important research subject for photovoltaic application. The soldering adhesion is a critical factor to module reliabilities. In this study, it discloses a non-destroyed method for soldering adhesion forecast of crystalline silicon solar cells. Combine the soldering adhesion test, the bus bar surface roughness measures and a numerical method to develop a numerical model. It could quickly calculate the soldering adhesion, analysis the screen-printing performance and judge the root cause of the soldering failure. The adhesion simulation result is in agreement with the experiment. The error is less 3% between the simulation and the experiment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
