impact to the graphene based electronic technology.

Defects engineering may enormously change kinetic and magnetic characteristics of graphene, extending a scope of its application in spintronics. The defects are usually produced as point defects, like substitutional- and interstitial- impurities and vacancies, either in the fabrication processes of a sample or by means of external factors, such as radiation or heavy-ion bombardment and chemical doping of a sample (see, e.g. \[\] for a review). The vacancies are formed in a crystal by reconstruction of the lattice as a result of knock-on of carbon atoms from the graphene lattice or/and as a result of bond rotations, e.g. the formation of Stone-Wales (55-77) and 8-ring defects, under bombardment with high-energy particles. A beam of the high-energy particles acts as a local heat source and thus helps to overcome the defect formation energy barrier. Note that a new class of the carbon-based materials has been experimentally revealed [@mmkr01], which has a nanoporous structure and it is catalycally active. The nanoporous carbon is less ordered than graphite but not completely amorphous. Theoretical studies have shown [@cs06] that an introduction non-hexagonal rings by means of vacancies into carbon structure most likely method to get a nanoporous
