Microscopia de força elétrica em amostra de óxido de grafeno
Silva, José Júnior Alves daCarbon-based structures have played a major role in scientific and technological fields. This is due to the versatility of the element carbon, the pillar of organic chemistry, which can form a variety of structures (about 10 million compounds), besides being a basic constituent of all known life forms. Depending on the conditions, this phenomenal element can occur in several allotropic forms: from an extremely ...
Adsorção de átomos alcalinos e halogênios em uma superfície de Grafeno: um estu...
Silva, José Júnior Alves daGraphene is currently the hottest topic in condensed-matter physics and materials science and was isolated less than four years ago. Graphene layers have been proposed as alternative materials for replacing carbon nanotubes in some applications, due to its easy synthesis and low costs. In order to explore potential applications of those nanostructures in electronic devices, through first principles based on the...
Antimicrobial effect of Dinoponera quadriceps (Hymenoptera: Formicidae) venom a...
Lima, Danya Bandeira; Torres, Alba Fabíola Costa; Mello, Clarissa Perdigão; Menezes, Ramon Róseo Paula Pessoa Bezerra; Sampaio, Tiago LimaAims: Dinoponera quadriceps venom (DqV) was examined to evaluate the antibacterial activity and its bactericidal action mechanism against Staphylococcus aureus. Methods and Results: DqV was tested against a standard strain of methicillinsensitive Staphylococcus aureus (MSSA), Staph. aureus ATCC 6538P and two standard strains of methicillin-resistant Staphylococcus aureus (MRSA), Staph. aureus ATCC 33591 and Sta...
