The effect of the surface heterogeneity and lateral interactions between admolecules on adsorption of homologous series of light n-alkanes on activated carbons (ACs) was studied. For alkanes, the possibility to occupy more than one adsorption site bz a molecule is taken into account, thus the multi-site occupancy adsorption was considered. The generalized form of the Dubinin–Astakhov isotherm equation has been applied, taking type of surface topography as well as interactions between the adsorbed molecules into consideration. Therefore, it is possible in terms of the assumed adsorption model to distinguish whether the AC surface in question can be better characterized by “patchwise”, “random” or “mediate” model of the surface topography. Isosteric heats of adsorption corresponding to the model of multi-site occupancy adsorption were calculated, because the heat of adsorption profile exhibits both the degree of energetic heterogeneity of the gas–solid system and the strength of the interactions between admolecules. The heat effects of single gases corresponding to the case of multi-site occupancy adsorption have not been studied yet. Our theoretical studies were extensively tested based on the experimental data taken from literature.

Completion of cirriculum programmes both within formal and informal educational sectors by using e-learning is still not very widespread. One of its’ form is so called blended learning – a hybrid curriculum combining traditional teaching methods (class meetings with teacher) with on-line learning. An example of such a curriculum is e-learning portal “Osobiście segreguję” [http://www.segreguje.org.pl/] developed by the Liga Ochrony Przyrody (Nature Conservation Ligue) focused on municipal issues waste. It comprises two courses, one addressed to teachers who basing on the curriculum materials available on the portal completed 8 lessons on current issues of municipal waste. It is present in details in the following manuscript. The second course, realized in the form of competition, was addressed to any individual registered at he portal. Results of both courses, particularly that addressed to the teachers, showed that e-learning as a new form of environmental education teaching, became...
