“…For sample G, the mean available surface area per silanol being 0.17 nm 2 (Table ), the silanols do not fill the surface; they are either clustered or randomly distributed over this surface . The Lorentzian derivative shape of the diluted silanol broad-line spectrum does not exclude the possibility that there are parts of the surface without silanols.…”

“…The preparation and the deuteration of the gel surface have been described previously. 24 The deuteration of the gel surface as well as the transformation of CD3OD into CDsOH were checked by infrared spectroscopy and found almost complete.…”

“…The assignment of the other losses is not trivial. The second weight loss could be due to the evolution of chemically bonded water that starts at about 200°C [36] and in some cases could end near 600°C [37]. However, we cannot rule out the evolution of some molecules of ethanol strongly H-bonded to the silica-PEG matrix.…”
