Characterization of specific interaction capacity of solid surfaces by adsorption of alkanes and alkenes. Part I: Adsorption on open surfaces
TL;DR: In this article, the double-bond influence of the double bond in the hydrocarbon adsorption phenomena has been examined, and thermodynamic parameters have been calculated which allow the estimation of specific parts of the alkene/silica interactions.

Study of modified silicas by inverse gas chromatography part II: Influence of chain length on surface properties of silicas grafted withα−ω diols
TL;DR: In this paper, the surface properties of silicas modified with α−ω diols having between 4 and 16 carbon atoms were investigated by inverse gas chromatography and it was shown that the value of the dispersive component of the surface energy does not change monotonously: a minimum value is recorded when the surface is covered by a monolayer of methylene groups.

Study of modified silicas by inverse gas chromatography. Part I: Influence of chain length on grafting ratio
TL;DR: In this paper, the grafting ratios were evaluated by elemental analysis of carbon or by the weight loss of the grafted silica heated to 700°C and it was shown that in the case of α-ω diols, the density of the grafts was 25% higher than for n-alcohols.

Study of modified silicas by inverse gas chromatography. Influence of chain length on the conformation of n-alcohols grafted on a pyrogenic silica
TL;DR: In this paper, a fumed silica surface was systematically modified by the grafting of n-alkyl chains with increasing carbon numbers, and the samples were characterized by the dispersive component of the surface energy, their specific interaction potential and enthalpies of adsorption of polar, in particular, alcohol probes.

Conformations of α-ω diols and n-alcohols grafted on silica studied by solid state 13C NMR
TL;DR: In this paper, high-resolution 13 C CP/MAS NMR of α-ω diols and n-alcohols terminally grafted on a planar pyrogenic silica, was used to determine the conformations of the molecules at the interface.
