Superconductivity in boron-doped diamond.
Superconductivity of boron-doped diamond, reported recently at T(c)=4 K, is investigated exploiting its electronic and vibrational analogies to MgB2. The deformation potential of the hole states arising from the C-C bond-stretch mode is 60% larger than the corresponding quantity in MgB2 that drives its high T(c), leading to very large electron-phonon matrix elements. The calculated coupling str...
متن کاملApplication of Boron-doped Diamond Electrodes for Wastewater Treatment
Boron-doped diamond (BDD) thin film is a new electrode material that has received great attention recently because it possesses several technologically important characteristics such as an inert surface with low adsorption properties, remarkable corrosion stability, even in strong acidic media, and an extremely wide potential window in aqueous and non-aqueous electrolytes. Due to these properti...
متن کاملEffect of nitro substituent on electrochemical oxidation of phenols at boron-doped diamond anodes.
In order to investigate nitro-substitutent's effect on degradation of phenols at boron-doped diamond (BDD) anodes, cyclic voltammetries of three nitrophenol isomers: 2-nitrophenol (2NP), 3-nitrophenol (3NP) and 4-nitrophenol (4NP) were studied, and their bulk electrolysis results were compared with phenol's (Ph) under alkaline condition. The voltammetric study showed nitrophenols could be attac...
متن کاملElectrochemical degradation of imazalil and pyrimethanil by anodic oxidation on boron-doped diamond
The electrochemical oxidation of mixture pesticides imazilil and pyrimethanil pesticides has been studied on borondoped diamond (BDD) electrodes on acid medium by bulk electrolysis. The influences of current density, conductive electrolyte, pH, and concentration of pesticide were investigated. GC and chemical oxygen demand measurements were conducted to study the reaction kinetics of pesticides...
متن کاملObservation of surface charge screening and Fermi level pinning on a synthetic, boron-doped diamond
Spectroscopic current-voltage (1-v) curves taken with a scanning tunneling microscope on a synthetic, boron-doped diamond single crystal indicate that the diamond, boiled in acid and baked to 500 “C in vacuum, does not exhibit ideal Schottky characteristics. These 1-V curves taken in ultrahigh vacuum do not fit the traditional theory of thermionic emission; however, the deviation from ideal can...
