Forward recoil spectrometry
WebSegregation to interfaces in two-phase blends containing diblock copolymers is fundamental to understanding the properties of these interfaces. In this study, the effect of homopolymer molecular weight on the segregation is examined by forward recoil spectrometry (FRES). WebHydrogen Forward Scattering Spectrometry (HFS) is a type of Elastic Recoil Detection Analysis (ERDA), that uses forward recoil to detect and quantify Hydrogen atoms in the surface and near surface layers of solid samples.
