Graphene oxide was successfully synthesized via oxidation of graphite, functionalized with dodecyl amine and then chemically reduced using hydrazine hydrate. The graphene oxide was also thermally reduced and exfoliated to obtain graphene. The results of different analyses mostly supported each other and demonstrated that different oxygen containing functional groups, those which were capable of grafting to dodecyl amine chains, have been created on the surface of graphite during the oxidation process at the expense of increased defects. Chemical reduction using hydrazine hydrate led to a low extent of oxygenic groups and defects as well as increased graphitization. It was also shown that dodecyl amine plays the role of a reduction agent during the functionalization process. Thermal treatment of graphene oxide resulted in a graphene structure.
Graphene Oxide: Synthesis and Characterization
Graphene nanosheets have a broad spectrum of biomedical applications. Hepatocellular cancer HCC is a major health problem in the Egyptian population. Currently, treatment strategies are invasive and have several adverse side effects. Thus, other approaches are required for managing this aggressive type of cancer. Our objective here was to prepare and characterize graphene oxide nanosheets and evaluate cytotoxic effect at the molecular level in an in vitro human liver cancer cell model HepG2. Graphene oxide nanosheets were generated by chemical oxidation and characterized by transmission electron microscopy and X-ray diffraction.
Metrics details. The microwave-absorbing properties of the composites were measured by a vector network analyzer. The XRD patterns show the single phase of strontium hexaferrite without other intermediate phases. TEM photographs reveal that strontium ferrite nanoparticles are uniformly dispersed on the surfaces of R-GO sheets. In recent years, the rapid growth of electronic equipment has put humans in increasing contact with each other, but it also results in serious electromagnetic pollution in civil and military applications, which is known as electromagnetic interference EMI.
Recent Trends in Nanomaterials pp Cite as. Graphene oxide is single or few atomic layers of graphene attached to oxygen-containing groups. It is a flexible material and is prepared by the energetic oxidation of graphite.

Как глупо с моей стороны. Прошу меня извинить. К человеку в моем положении часто приходят с… ну, вы понимаете. - Да, мистер Клушар, конечно, понимаю. Это цена, которую приходится платить за известность.
Тут он услышал знакомый металлический скрежет и, подняв глаза, увидел такси, спускавшееся вниз по пандусу в сотне метров впереди. Съехав на эту же улицу, оно начало набирать скорость, двигаясь прямо в лоб мотоциклу. Он должен был бы удариться в панику, но этого не произошло: он точно знал, куда держит путь. Свернув влево, на Менендес-пелайо, он прибавил газу. Мотоцикл пересек крохотный парк и выкатил на булыжную мостовую Матеус-Гаго - узенькую улицу с односторонним движением, ведущую к порталу Баррио - Санта-Крус. Еще чуть-чуть, подумал .
