We report on the synthesis of multifunctional microdiamonds by chemical vapor deposition (CVD) 304 and 316 austenitic stainless steel (SS) substrates. The increase in wettability achieved surface scratching structure ultra-dense Q-carbon high nucleation density minimized strains diamond films. Notably, these films exhibit a amount twinning, leading to formation five-fold microdiamonds. diamonds...

nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. importance of the magnetic nanomaterials in biomedical science cannot be overlooked. the most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. however monodispersion, selection of an appropriate coati...

Synthesis of multilayer graphene on copper wires by a chemical vapor deposition method is reported. After copper etching, the multilayer tube collapses forming stripes of graphitic films, their electrical conductance as a function of temperature indicate a semiconductor-like behavior. Using the multilayer graphene stripes, a cross junction is built and owing to its electrical behavior we propos...

Nanocrystalline zinc oxides are produced by chemical vapor synthesis and characterized by x-ray diffraction, high resolution transmission electron microscopy, nitrogen sorption, and extended x-ray absorption fine structure. Dopant elements aluminum, gallium, and indium influence the particle size of the powders as well as lattice parameters and local structure. The different effects of the thre...

Single-walled carbon nanotubes are synthesized by chemical vapor deposition of methane at controlled locations on a substrate using patterned catalytic islands. The combined synthesis and microfabrication technique presented here allows a large number of ohmically contacted nanotube devices with controllable length to be placed on a single substrate. Transport studies demonstrate ohmic contacti...

We report the electronic properties of large scale graphene films grown by chemical vapor synthesis on Ni and Cu, and then transferred to SiO2/Si substrates. We have observed electric field effect and measured carrier mobilities in the samples to be on the order of 10 cm/Vs . We have also measured low temperature magnetoresistance and studied characteristic universal conductance fluctuations on...

The synthesis of Fe, Fe-Pt and Fe-Co nanoparticles were carried out using the bottom-up polyol process using standard ari free techniques. Using these nanoparticles, multiwalled carbon nanotubes were synthesized in an atmospheric pressure plasma enhanced chemical vapor deposition(APPECVD) process with a mixture of helium and acetylene gases. The APPECVD process produced dense carbon nanotube fo...

We report the synthesis of a Fe-porphyrin-like carbon nanotube from conventional plasma-enhanced chemical vapor deposition. Covalent but seamless incorporation of the 5-6-5-6 porphyrinic Fe-N(4) moiety into the graphene hexagonal side wall was elucidated by x-ray and ultraviolet photoemission spectroscopies and first-principles electronic structure calculations. The resulting biomimetic nanotub...
