In situ interferometric observation of the process of CO2 dissolving into PMMA (polymethyl methacrylate) was carried out at high pressure and room temperature, in view of the interest to polymer foam technology. By analysing interferograms, the phase

The preparation of SiO2-TiO2 aerogels by supercritical impregnation of titanium alkoxides into silica alcogels was investigated. A mixture of CO2 and 2-propanol with dissolved titanium tetraisopropoxide modified with acetylacetone was used as the imp

Silica–titania aerogels were prepared by impregnating titanium tetraisopropoxide modified with acetylacetone into a silica alcogel followed by supercritical drying. The effects of the impregnation conditions, the supercritical drying medium (ethano

A simple system for high‐pressure FTIR measurements was designed and tested. This system can be applied to physicochemical measurements and in situ analysis of chemical reactions in supercritical fluids. The principle of the high‐pressure IR opti
