AbstractA qualitative interpretation is proposed to interpret isosteric heats of adsorption by considering contributions from three general classes of interaction energy: fluid–fluid heat, fluid–solid heat, and fluid—high‐energy site (HES) heat. Multiple temperature adsorption isotherms are defined for nitrogen, T=(75, 77, 79) K, argon at T=(85, 87, 89)

Abstract CO is adsorbed at 298 K only on the (0001) faces of polycrystaltine αCr 2 0 3 with the appearance of a single i.r. peak whose frequency shifts from 2185 (θ ≈ 0) to 2170 cm -1 (θ max ). This shift is due to the building up of adsorbate-adsorbate interactions (dynamic and static). The dipole--dipole (dynamic) interaction has been measured by

Quantitative Determination of Adsorbate-Adsorbate Interactions
Physical Review Letters, 1999A new concept called configuration distribution analysis is introduced to extract quantitative information on adsorbate-adsorbate interactions from high-resolution scanning tunneling microscopy data. From atom-resolved nitrogen island configurations on an Fe(100) surface we show that the propensity to form small, compact $c(2\ifmmode\times\else ...

Abstract We investigated the chemisorption of Na and K alkali-metal atoms on the Al(111) surface from very low coverages (Θ = 1 16 ) up to full a monolayer. The calculations predict site and bond-length changes of the adsorbate atoms, as well as a condensation into islands with increasing coverage. Some processes are activated which implies

Adsorbate-adsorbate association on a homogenous surface of a nonspecific adsorbent
Journal of Colloid and Interface Science, 1972Abstract Various methods for calculating the degree of association of molecules adsorbed on a homogeneous surface of an adsorbent have been examined. Equations for the isotherms and heats of adsorption and heat capacity of the adsorbate have been derived using a model of chain association of the molecules parallel to the surface in the first layer ...

The apparent density of the adsorbate and the adsorption isotherm have been measured in the systems carbon tetrachloride – charcoal and diethyl ether – charcoal. In both, the apparent density of the adsorbate is lower than the normal liquid density. These abnormally low values cannot be explained on the basis of the coexistence of 'vapor' and 'liquid'
