Structural studies on physical gels, based on a triblock copolymer and a solvent selective for its midblocks, are presented. Gel formation in such systems arises due to interconnected microdomains that form the junctions in a three-dimensional network. Small angle X-ray scattering studies revealed t
## Abstract Trace elements in different silica gels are determined by neutron activation analysis. The presence of 20 elements in the ppm range and of 15 elements in the ppb range is established in all silica gels; even in spherical material probably obtained via an organosilicium starting material
