Special Issue Information

Dear Colleagues,

Ever since the Nobel Prize was awarded in 2010 to Andre Geim and Kostya Novoselov “for groundbreaking experiments regarding the two-dimensional material graphene”, the number of research contributions including graphene in one way or another has grown exponentially, taking many different directions in search of new promising applications of these fascinating two-dimensional (2D) materials.

Although there are now an increasing number of 2D layers that are not produced from graphene or graphite, there is still a rather wide group of materials that can be related to graphene because of the presence of polyaromatic units or because of the reaction of the original substance with several functional groups that eventually lead to the modification of the structure in different scales. In the first case, among others, the family of graphynes is now very popular, and also holey graphenes, in which holes or pores of different dimensions and geometries can be tailored by removing a large amount of atoms or “rings” from the 2D plane. The presence of the pores together with the possible presence of different functional groups makes these porous derivatives very attractive for several applications, ranging from electronic and energy storage to their use as filters at the molecular level or as an interesting tool for molecular recognition.

If we include multilayered compounds, graphene flakes, and carbon nanotubes, the research possibilities offered by what we can consider in one way or another nanoporous derivatives of graphene is very large, and we welcome articles, communications, and reviews that can be included under all these types of exciting nanoporous materials, together with their description, fabrication or applications in any field.

We report accurate quantum calculations of the sieving of Helium atoms by two-dimensional (2D) graphtriyne layers with a new interaction potential. Thermal rate constants and permeances in an ample temperature range are computed and compared for both Helium isotopes. With a pore larger than graphdiyne, the most common member of the γ-graphyne family, it could be expected that the appearance of quantum effects were more limited. We find, however, a strong quantum behavior that can be attributed to the presence of selective adsorption resonances, with a pronounced effect in the low temperature regime. This effect leads to the appearance of some selectivity at very low temperatures and the possibility for the heavier isotope to cross the membrane more efficiently than the lighter, contrarily to what happened with graphdiyne membranes, where the sieving at low energy is predominantly ruled by quantum tunneling. The use of more approximate methods could be not advisable in these situations and prototypical transition state theory treatments might lead to large errors. Full article

The physical adsorption of cisplatin (CP) on graphene oxide (GO) and reduced graphene oxide (rGO) is investigated at the DFT level of theory by exploiting suitable molecular prototypes representing the most probable adsorbing regions of GO and rGO nano-structures. The results show that the CP binding energy is enhanced with respect to that for the interaction with pristine graphene. This is due to the preferential adsorption of the drug in correspondence of the epoxy and hydroxy groups located on GO basal plane: an energy decomposition analysis of the corresponding binding energy reveals that the most attractive contribution comes from the electrostatic attraction between the -NH 3 ends of CP and the oxygen groups on (r)GO, which can be associated with hydrogen bonding effects. Moreover, it is found that the reactivity of the physically adsorbed CP is practically unaltered being the free energy variation of the first hydrolysis reaction almost matching that of its free (unadsorbed drug) counterpart. The reported results suggest that the CP physical adsorption on GO and rGO carriers is overall feasible being an exergonic process in aqueous solution. The CP adsorption could facilitate its solubility and transport in water solutions, exploiting the high hydrophilicity of the peripheral carboxylic groups located on the edge of the GO and rGO nano-structures. Moreover, the the higher affinity of CP with respect to the oxidized sites suggests a possible dependence of drug loading and release on pH conditions, which would highly facilitate its specific delivery.
