Pristine graphene is strongly diamagnetic. However, graphene with single carbon atom defects could exhibit paramagnetism. Theoretically, the π magnetism induced by the monovacancy in graphene is characteristic of two spin-split density-of-states (DOS) peaks close to the Dirac point. Since its prediction, many experiments have attempted to study this π magnetism in graphene, whereas only a notab...

Numerical simulations of current-voltage curves in electron-only devices are used to discuss the influence of charged defects on the information derived from fitting space-charge-limited current models to the data. Charged, acceptor-like defects lead to barriers impeding the flow of electrons in electron-only devices and therefore lead to a reduced current that is similar to the situation where...

background: some congenital defects can be prevented in the pregestational stage. however, many health professionals are not prepared to provide counselling to couples regarding the same. objective: this study aimed to assess the performance of doctors and nurses from a primary health-care unit in florianopolis, brazil, in preventing birth defects in the preconception period based on the recomm...
