Here the contributors of these seven articles present their findings and offer reviews in such studies as a molecular dynamic description of clusters in strong fields (a simple model in which core and covalence electron are treated at the same level as Coulomb interacting particles), extended universality in a statistical mechanical model (in a specific family of systems), a unified scaling picture for a metal-insulator phenomena in two dimensions, phase transitions and hysteresis in a system of two coupled magnetic nanoparticles, recent advances in electronic and vibration studies of carbon nanotubes using fullerenes, effects of apical oxygen ordering, and geometric effects and magnetic phases in quantum rings.

Conductimetric experiments showed that the binding of Cd, Cu, and Zn has a significant electrostatic contribution, whereas for Pb there is a higher level of covalence in the binding of humic acids, which could result in the higher release and movement of Cd but lower mobility of Pb in the soil-plant system (Pinheiro et al.
