Graphene Edge Spins: Spintronics and Magnetism in Graphene Nanomeshes

We have fabricated low-defect graphene nanomeshes (GNMs) by using a non-lithographic method and observed large-amplitude ferromagnetism even at room temperature, only when pore edges of the GNMs were hydrogenterminated. The observed correlation between the inter-pore spacing and magnetism and also magnetic force microscope observations suggest that it is attributed to polarzied electron spins l...

study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...

Tunable magnetism in metal adsorbed fluorinated nanoporous graphene

Developing nanostructures with tunable magnetic states is crucial for designing novel data storage and quantum information devices. Using density functional theory, we investigate the thermodynamic stability and magnetic properties of tungsten adsorbed tri-vacancy fluorinated (TVF) graphene. We demonstrate a strong structure-property relationship and its response to external stimuli via defect ...
