Observation of a one-dimensional adsorption site on carbon nanotubes: Adsorption of alkanes of different molecular lengths

Article Abstract:

Temperature-programmed desorption (TPDD) is used to characterize the adsorption of several alkanes and hybrid Monte Carlo simulations are used to probe the molecular-level details of alkanes adsorbed on different sites on the single-wall carbon nanotube (SWNT) bundles. The groove sites behaved as one-dimensional adsorption space, demonstrating an inverse dependence of capacity on the length of the adsorbed molecule, whereas the capacity of the internal sites depended inversely on the volume occupied by the molecule.

Adsorption and mixing behavior of ethers and alkanes at the solid/liquid interface

Article Abstract:

Differential scanning calorimetry (DSC) is used to describe the behavior of binary mixtures of linear symmetrical ethers and alkanes adsorbed to a graphite surface from the bulk liquid mixtures. The mixing behavior is interpreted in terms of the sizes of the adsorbed molecules, their monolayer packing and the mutual repulsion of adjacent ether oxygens.

The formation of solid monolayers of linear amines adsorbed on graphite from the liquid

Article Abstract:

Solid monolayer formation by all the linear amines from C6 to C16 adsorbed from their liquids to a graphite surface is demonstrated. All the long linear amines from C6 to C16 form a solid monolayer that coexists with the bulk liquid adsorbate when adsorbed on graphite.
