Graphene research, in our lab, is concentrated on growth of graphene over a wide range of transition metals, and thin fi lms, of size from 1 cm × 1 cm up to as large as 16 cm × 6 cm and their application in energy and electronics. During graphene growth, both metal foils (Ni and Cu, thickness ~ 50-200 mm) and thin fi lms (Ni and Cu, 300-500 nm thick) were used as substrate. For the latter context, Ni and Cu thin fi lms were deposited on SiO 2 /Si substrates using RF magnetron sputtering system and Ebeam evaporation. Before s...

Flipping growth orientation of nanographitic structures by plasma enhanced chemical vapor deposition

“…[1][2][3][4] Recently, a considerable interest is shown to grow large area vertical graphene nanosheets (VGNs), also called as carbon nanowalls (CNWs), and a few layer planar nanographite (FPNG) structures because of their potential applications in various fields. [2][3][4][5] The VGNs have unique structural and electrical characteristics with high aspect ratio and large three dimensional networks which make them an excellent candidate for field emission, fuel cells, chemical & biosensors and energy storage devices. [2][3][4][5][6] The FPNG films can also be used for transparent conductive films and flexible electronics.…”

Effect of Magnetic Nanoparticles on Tobacco BY-2 Cell Suspension Culture

“…Nanomaterials, especially nanoparticles, can be linked with different biologically active molecules, which can exactly direct them to specific sites within biomolecules including proteins and nucleic acids, sub-cellular, cellular, tissue and body structures [3,4]. Due to above mentioned properties, nanoparticles have found a wide range of applications, especially in industry (textile industry—silver nanomaterials with antibacterial properties) [5,6,7,8,9], electronics (high resolution imaging, logical circuits on the molecular levels) [10,11,12,13], agriculture (wastewater treatment), cosmetics (TiO 2 as UV protective agent) and medicine [14,15]. The possibility of nanoparticle targeting enables their application in imaging methods, and in the transport of active compounds in the treatment of different threats, especially malignant ones [3,16,17,18,19,20].…”
