(Elsevier, 2010-08)Pt/BaO/Al2O3 catalysts react with NO/O2 mixtures to form barium nitrites and nitrates. In the presence of small amounts of C(s) admixed with the catalyst the concentrations of NOx adsorbed is considerably reduced and the ...
-
(Springer, 2013-01-01)The effect of various organic solvents on the catalytic activity, stability and substrate specificity of alchohol dehydrogenase from Haloferax volcanii (HvADH2) was evaluated. The HvADH2 showed remarkable stability and ...
-
(Kluwer Academic Publishers-Plenum Publishers, 2002-04)A series of Cu catalysts were studied as a function of support (Al2O3, TiO2 and SiO2) and Cu precursor (ex-SO4 and ex-NO3) for activity in the SCR-NH3 reaction. The catalysts were characterized using NOx TPD and SEM/EDAX ...
-
(RSC Publishing, 2010)The photophysics and photochemistry of [Cr(phen)2(dppz)]3+ and its 11,12-substituted derivatives [Cr(phen)2(X2dppz)]3+ {X = Me or F} have been studied in the presence of purine nucleotides or DNA using steady state and ...
-
(RSC Publishing, 2010)Abnormal isoxazolylidene complexes, a new subclass of mesoionic complexes containing an isoxazolium-derived carbene type ligand, have been synthesised via oxidative addition and compared to structurally related mesoionic ...
-
(Elsevier, 2011-12)Central to understanding how nanoscale objects interact with living matter is the need for reproducible and verifiable data that can be interpreted with confidence. Likely this will be the basis of durable advances in ...
-
(Elsevier, 2010-03-31)An efficient one-pot synthesis is described for the preparation of 1,4-disubstituted piperazine-2,5-diones starting from a suitable amine and chloroacetyl chloride in the presence of an aqueous base. The resulting chlo ...
-
(Springer Science+Business Media, 2012-11)The EE subunit of horse liver alcohol dehydrogenase (HLADH-EE) has been subcloned in pRSETb vector to generate a fusion His-tag protein. The migration from a multistep purification protocol for this well-known enzyme to ...
-
(RSC Publishing, 2012)Carbon based materials are attractive for biological applications because of their excellent biocompatibility profile. Porous carbons with high specific surface area are particularly interesting because it is possible in ...
-
(Elsevier, 2005-07)Na/Al2O3 catalysts are tested in the soot oxidation reaction using O-2 and NO/O-2 as oxidising agents. The activity of the catalysts . varies with oxidising agent and the presence of surface SO42-.. NO(g) increases conversion ...
-
(Springer, 2011)The wastewater generated at a facility specialising in potato processing was found to contain high levels of insoluble potato starch. Several separation methods were employed to obtain maximum potato starch recovery from ...
-
A magnetic iron(III) switch with controlled and adjustable thermal response for solution processing (RSC, 2012-02-27)Spin crossover requires cooperative behaviour of the metal centers in order to become useful for devices. While cooperativity is barely predictable in solids, we show here that solution processing and the covalent introduction ...
-
(RSC, 2009)Main-chain organometallic polymers were synthesized from bimetallic iron(II)complexes containing a ditopic N-heterocyclic carbene (NHC) ligand [(cp)(CO)LFe(NHC~NHC)Fe (cp)(CO)L]X2 (where NHC~NHC represents a bridging ...
-
(Springer, 2013-04)Two Al2O3-supported alkaline earth metal oxide catalysts (MgO and BaO) were contacted with valeric acid at 250 °C. Each formed amounts of 5-nonanone (BaO more than MgO). A significant deposition of hydrocarbonaceous material ...
-
(Elsevier, 2010-10-13)The use of I2/AgOAc in dichloromethane constitutes a cheap, mild, and efficient method for the selective iodination of a variety of heterocycles. In a number of cases, this method provides superior yields than other ...
-
(Elsevier, 2005-02-10)The temperature-programmed activity of a series of oxide-supported (TiO2, Al2O3 and SiO2) Cu catalysts formed from two different Cu precursors (Cu(NO3)(2) and CuSO4) for the selective catalytic reduction of NOx using ...
-
(Elsevier, 2012-01)N-heterocyclic carbene (NHC) coordination to a cobalt(III) center embedded in a porphyrin scaffold has been accomplished by decarboxylation from N,N’-dimethylimidazolium-2-carboxylate in the presence of Co(TPP)Cl (TPP = ...
-
(RSC Publishing, 2010)The expansion of the concept of N-heterocyclic carbenes as ligands for transition metals to mesoionic ligand systems has led to the discovery of a wide range of non-classical carbene-type ligands. These non-classical ...
-
(Elsevier, 2012-09)A new practical and efficient synthesis of alpha-keto acids was accomplished starting from the synthon 1,4-diacetylpiperazine-2,5-dione. The synthesis encompasses both aromatic and aliphatic substrates proving to be versatile ...
-
(Elsevier, 2009-04-15)A simple and efficient one-step procedure is described for the synthesis of a number of symmetrical 1,4-disubstituted piperazine-2,5-diones under phase transfer conditions. The reactions are carried out at room temperature, ...
