Homogeneous energy

In the most simple case of ideal, energy homogeneous surface the adsorption equilibrium of non-interacting particles is described by the Langmuir isotherm [33] ...

The adsorption sites have the same energy (homogeneous surface), no interaction between the adsorbed molecules. It means that the adsorption energy is independent of coverage. 

Boudreau and Cooper showed that adsorptive energy distributions can be computed directly from chromatograms (38)- Their method is similar in principle to the present analysis, except for the use of an adsorption isotherm equation that provides an analytical solution for Equation 15. This simplification, which describes all adsorption isotherms as if they occur below the two-dimensional critical temperature 7 c = 0.60 (6), speeds computation of the histogram. Its practical effect is to broaden the energy scale artificially, however, particularly when light vapors are used to characterize low energy, homogeneous substrates. 

The use of a high-energy homogenization step to prepare the submicrometer-sized monomer droplets for the Pickering miniemulsion process could be a drawback for industrial scale-up. A better outcome could be achieved by the equivalent emulsion polymerization process in which solid nanoparticles were used as solids stabilizer. 

Catalyst selectivity is closely connected with adsorption properties which were studied in this work by the method of hydrogen TPD. Fig.3 presents TPD-curves of catalysts from fresh and 6-month stored HA alloys. The surface of a catalyst from fresh Ni4oAlgo is fhe most energy-homogeneous. It adsorbs, mainly, weakly bound hydrogen...
