Diamond growth in a novel low pressure flame
Diamond growth using a new low-pressure combustion technique is reported. A large-area hydrogen/oxygen flame is used as the source of atomic hydrogen. Methane diluted in hydrogen is injected into the flame near a heated silicon substrate, on which diamond crystallites nucleate and grow. This technique is potentially capable of large-area film growth, since atomic hydrogen can be generated unifo...
متن کاملTomographic analysis of CO absorption in a low-pressure flame.
Tomographic analysis is used to provide a correction to low-pressure stoichiometric premixed CH(4)/O(2) flame temperatures measured with tunable diode laser absorption spectroscopy employing CO two-line thermometry. It is shown that flame temperatures measured with line-of-sight-based two-line thermometry are always too low and that the correction to the observed temperature is a nonlinear func...
متن کاملSynthesis of nanocomposite metallic oxides in a doped low- pressure flame reactor
The importance of nanosized material in many contemporary applications is already known. However special properties such as superparamagnetism, semi-conducting and photocatalysis are unique to single metallic oxide. Recent advances in information technology, catalysis, and medicine often require materials that posses a combination of two or more of these properties. Nanocomposite materials pres...
متن کاملAn XPS study of platinum nanoparticles prepared by a low-pressure flat flame
The one-step synthesis and characterization of nanostructured metallic platinum microspheres by a low-pressure flat flame technique is presented here. Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS) analyzed the as-derived powders. Collectively, the results obtained from these analyses confirmed the formation of microsphere...
متن کاملComputational Studies of Flame - Flow Interactions
One of the major problems in turbulent combustion is to predict the turbulent burning velocity, which can be increased by the turbulence compared to the laminar burning velocity. This requires the solution to a reacting ow problem, where the turbulence is coupled to the chemical reaction. The diculties lie in the fact that many disparate spatial and temporal scales are present in the convection...
