Using high resolution transmission electron microscopy, we identify the specific atomic scale features in chemically derived graphene monolayers that originate from the oxidation-reduction treatment of graphene. The layers are found to comprise defect-free graphene areas with sizes of a few nanometers interspersed with defect areas dominated by clustered(More)
In this paper an advance overview of our activity in the field of near-infrared silicon photodetectors, is presented. Proposed photodetectors are based on the internal photoemission effect through a Schottky junction and their fabrication results completely compatible with the silicon technology. Taking advantages by both new structures and new(More)
Glutamate is the principal excitatory amino acid neurotransmitter abundantly present in the brain of mammals, as well as in dietary protein, released by an estimated 40% of all synapses and its interaction and participation with specific membrane receptors in plastic changes in the efficacy of synaptic transmission are responsible for many neurological(More)
