Hydrogen generation from alcohols catalyzed by ruthenium-triphenylphosphine complexes : multiple reaction pathways
(2010-06-16) - Journal article
We report a comprehensive density functional theory (DFT) study of the mechanism of the methanol dehydrogenation reaction catalyzed by [RuH2(H2)(PPh3)3]. Using the B97-D dispersion-corrected functional, four pathways have ...
Application of infiltrated LSCM-GDC oxide anode in direct carbon/coal fuel cells
(2016-08-01) - Journal article
Hybrid direct carbon fuel cells (HDCFCs) utilise an anode based upon a molten carbonate salt with an oxide conducting solid electrolyte for direct carbon conversion. They can be fuelled by a wide range of carbon sources, ...

Phase transition behavior of the layered perovskite CsBi0.6La0.4Nb2O7 : a hybrid improper ferroelectric
(2017-05-13) - Journal article
The phase behavior of the layered perovskite CsBi0.6La0.4Nb2O7, of the Dion-Jacobson family, has been studied by high-resolution powder neutron diffraction between temperatures 25 < T < 850 °C. At ambient temperature this ...
Electrochemical impedance spectroscopy investigation of the anodic functionalities and processes in LSCM-CGO-Ni systems
(Electrochemical Society, 2015) - Conference item
Electrochemical impedance spectroscopy was used to characterize anode compositions made of (La0.75Sr0.25)0.97Cr0.5Mn0.5O3 (LSCM) and gadolinia doped ceria (CGO) with and without additional submicron Ni, or exsoluted Ni ...
Nonequilibrium ferroelectric-ferroelastic 10-nm nanodomains : wrinkles, period-doubling, and power-law relaxation
(2017-08-02) - Journal article
Since the 1935 work of Landau and Lifshitz and of Kittel in 1946 all ferromagnetic, ferroelectric, and ferroelastic domains have been thought to be straight-sided with domain widths proportional to the square root of the ...
Three closely related 1-[(1,3-benzodioxol-5-yl)methyl]-4-(halobenzoyl)piperazines : similar molecular structures but different intermolecular interactions
(2019-02-01) - Journal article
In each of the compounds 1-[(1,3-benzodioxol-5-yl)methyl]-4-(3-fluorobenzoyl)piperazine, C19H 19FN 2O 3 (I), 1-[(1,3-benzodioxol-5-yl)methyl]-4-(2,6-difluorobenzoyl)piperazine, C19H 18F 2N 2O 3 (II), and 1-[(1,3-ben ...
Wetting and interactions of Ag–Cu–Ti and Ag–Cu–Ni alloys with ceramic and steel substrates for use as sealing materials in a DCFC stack
(2016-02) - Journal article
Ag and Ag-based pseudo-alloys were evaluated in terms of application as metal brazes for the use in a hybrid direct carbon fuel cell stack. This paper reports on a series of wetting experiments on systems of pure Ag as ...
Exploiting the imidazolium effect in base-free ammonium enolate generation : synthetic and mechanistic studies
(2016-11-07) - Journal article
N-Acyl imidazoles and catalytic isothiourea hydrochloride salts function as ammonium enolate precursors in the absence of base. Enantioselective Michael addition-cyclization reactions using different α,β-unsaturated Michael ...
Flash vacuum pyrolysis of α-acyl-o-methoxybenzylidenetriphenylphosphoranes to give 2-substituted benzofurans
(ARKAT, 2000) - Journal article
The title stabilised ylides, readily prepared in one step from acid chlorides, are converted upon FVP at 850 °C into 2-substituted benzofurans. When the acyl group is aromatic it appears unchanged as the 2- substituent in ...
