Oxygen reduction and hydrogen peroxide are technologically important reactions in the fields of energy generation sensing. Metal-doped graphenes, where metal serves as catalytic center graphene high area conductor, have been used electrocatalysts for such applications. In this paper, we investigated use uranium–graphene thorium–graphene hybrids prepared by a simple scalable method. The were synthesized thermal exfoliation either uranium- or thorium-doped oxide various atmospheres....
Defect accumulation and annealing phenomena in Si-implanted monoclinic gallium oxide (β-Ga2O3) wafers, having (2¯01), (010), (001) orientations, were studied by Rutherford backscattering spectrometry channeling mode (RBS/c), x-ray diffraction (XRD), (scanning) transmission electron microscopy [(S)TEM]. Initially, the samples with different surface orientations implanted 300 keV 28Si+-ions, applying fluences range of 1 × 1014–2 1016 Si/cm2, unveiling interesting disorder kinetics. In...
Plasma polymerization of allylamine is performed both in continuous wave and pulsed mode. Chemical derivatization applied to determine primary secondary amine concentration. Primary amines are efficiently formed, but more abundant. A mechanism proposed account for the difference content obtained from comparison between mode plasma polymerization. The AFM measurements on ultrathin (1-10 nm) polymers confirm continuity films that film growth silicon occurs via a layer-by-layer because no...
In this paper, the effect of light ion irradiation on graphene oxide foil structure and composition was studied.
For the past decade, researchers have been trying to understand mechanism of thermal reduction graphite oxide. Because deuterium is widely used as a marker in various organic reactions, we wondered if deuterium-labeled oxide could be key fully this mechanism. Graphite oxides were prepared by Hofmann, Hummers, Staudenmaier, and Brodie methods, analogue was synthesized Hofmann method. All analyzed not only using traditional techniques but also gas chromatography–mass spectrometry (GC-MS)...
This review summarizes the development of Gas-Cooled Fast Reactor (GFR) concept from early 1970s until now, focusing specifically on structural materials and advanced fuel cladding materials. Materials for future nuclear energy systems must operate under more extreme conditions than those in current Gen II or III systems. These include higher temperatures, a displacement per atom, corrosive environments. paper reviews previous GFR concepts light several promising candidate system. It also...
Chemical synthesis of graphene relies on the usage various chemical reagents. The initial step, in which graphite is oxidized to oxide, achieved by a combination oxidants and acids. A subsequent reduction step eliminates/reduces most oxygen functionalities yield graphene. We demonstrate here that these treatments significantly contaminate with heteroatoms/metals, depending procedures followed. Contaminations heteroatoms (N, B, Cl, S) or metals (Mn, Al) were present at relatively high...
The paper discusses the deposition of protective coatings ranging from organosilicon plasma polymers to SiO2-like films and hard diamond-like carbon/silicon oxide (DLC : SiOx) in radio frequency capacitively coupled discharges using hexamethyldisiloxane (HMDSO). As a result optimization conditions it was possible obtain high performance coatings. In HMDSO/O2 mixture, shown that rather than film cross-linked SiOxCyHz polymer can be used as coating for polycarbonate. optimum an almost...
Abstract Summary: Five hundred nanometer thick organosilicon coatings are prepared on Si substrates in parallel by the plasma‐assisted polymerisation of hexamethyldisiloxane (HMDSO) an RF‐inductively coupled plasma (RFICP) and distributed electron cyclotron resonance (DECRP) at low pressure (0.27 Pa) tetramethyldisiloxane (TMDSO) premixed with oxygen N 2 microwave induced remote afterglow (MIRA) 560 Pa. The structure these different films is analyzed techniques, such as Fourier‐transform...
