FTIR spectroscopic characterization of NOx species adsorbed on ZrO2 and ZrO2-SO42-
(American Chemical Society, 2002)The nature of the NOx species produced during the adsorption of NO at room temperature and during its coadsorption with oxygen on pure and sulfated zirconia has been investigated by means of in situ FTIR spectroscopy. The ... -
Mesoporous metallic rhodium nanoparticles
(Nature Publishing Group, 2017)Mesoporous noble metals are an emerging class of cutting-edge nanostructured catalysts due to their abundant exposed active sites and highly accessible surfaces. Although various noble metal (e.g. Pt, Pd and Au) structures ... -
Metal dicyanamides as efficient and robust water-oxidation catalysts
(Wiley Blackwell, 2017)Non-oxide cobalt-based water-oxidation electrocatalysts have received attention recently for their relative ease of preparation, they are stable both in acidic and basic media, and they have higher turnover frequencies ... -
One-dimensional copper (II) coordination polymer as an electrocatalyst for water oxidation
(Wiley-VCH Verlag, 2017)Although cobalt-based heterogeneous catalysts are the central focus in water oxidation research, interest in copper-based water oxidation catalysts has been growing thanks the great abundance of copper and its biological ... -
Operation of carbon nanotube thin-film transistors at elevated temperatures
(IEEE, 2009-12)The authors study the operation of carbon nanotube thin-film transistors (CNT-TFT) at elevated temperatures. Due to the small bandgap of semiconducting carbon nanotubes, CNT-TFTs are not suitable to be developed as ... -
Phase separation in liquid crystalline mesophases of [Co(H 2O)6]X2: P65 Systems (X = NO3-, Cl-, or ClO4-)
(2007)Transition-metal aqua complex salts [M(H2O)6]X 2 (where M is Mn(II), Co(II), Ni(II), Zn(II), or Cd(II) and X is NO3-, Cl-, or ClO4-) can be dissolved in triblock poly(ethylene oxide) - poly(propylene oxide) - poly(ethylene ... -
Selective catalytic ammonia oxidation to nitrogen by atomic oxygen species on Ag (111)
(American Chemical Society, 2017)Ammonia-selective catalytic oxidation was studied on the planar Ag(111) single-crystal model catalyst surface under ultra-high-vacuum (UHV) conditions. A variety of oxygen species were prepared via ozone decomposition on ... -
Soft x-ray photoemission studies of Hf oxidation
(A I P Publishing LLC, 2003)Charging of oxide films under x rays is an important issue that must be taken into consideration for determination of core-level binding energies as well as valence band offsets. Measurements are taken as a function of ... -
Spectroelectrochemistry of potassium ethylxanthate, bis(ethylxanthato)nickel(II) and tetraethylammonium tris(ethylxanthato)-nickelate(II)
(Royal Society of Chemistry, 2001)Electrochemical and chemical oxidation of S2COEt−, Ni(S2COEt)2, and [Ni(S2COEt)3]− have been studied by CVand in situ UV-VIS spectroscopy in acetonitrile. Cyclic voltammograms of S2COEt− and Ni(S2COEt)2 display one (0.00 ... -
Spectroscopic characterization of vanadium(v) oxo species deposited on zirconia
(Royal Society of Chemistry, 2000)A method for deposition of vanadium(v) oxo species from acidic solutions of ammonium metavanadate on zirconia is described. The samples are synthesized by suspension of the support (powder) in solutions containing three ... -
Spectroscopic investigation of onset and enhancement of electrical conductivity in PVC/PANI composites and blends by γ-ray or UV irradiation
(American Chemical Society, 1998)Electrical conductivity of blends and composites of poly(vinyl chloride) (PVC) with nonconducting polyaniline (PANI) increases when they are subjected to γ-rays or UV radiation. This is attributed to a radiation-induced ... -
