Liquid–liquid extraction and ion-exchange chromatography are efficient methods for sequestration of metal ions, but these methods are poorly suitable for microfluidic miniaturization. Here we examine several methods for rapid extraction, fluorometr

Shrinkage during polymerization and processing of silica and hybrid organic−inorganic xerogels prohibits net-shape fabrication and introduces stresses that often result in cracking. In this study, we have used a new class of hybrid organic−inorga

Silsesquioxanes are a family of siloxane network polymers that have become important as vehicles for introducing organic functionalities into sol−gel materials. However, there has not been a systematic study of the capacity of organotrialkoxysilane

The reactions of the incompletely condensed polyhedral oligosilsesquioxanes with excess Me 5 Sb result in the formation of the corresponding stibonium-substituted silsesquioxanes. These stibonium siloxides show enhanced reactivity toward main group a

A new class of thermally robust sol-gel polymers have been prepared from the disilaoxacyclopentane derivative 1 by ring-opening polymerization to form nonshrinking polysiloxanes. This reaction, which does not need solvent or water, can be used for, a
