Sol-gel mineralization has been used and evaluated as a tool for morphological studies on Picea abies and Betula verrucosa. Wood specimens and a pulped spruce sample were impregnated with a silica sol-gel and subsequently heated (calcined) to condense the surfactant-templated polysilicic acid into structured mesoporous silica. During this calcination process, the wood substance and the surfactant were removed and a silica-cast replica of the sample was obtained. The sol-gel mineralization...[Show more]
