Quantum dot (QD) sensitized NiO photocathodes rely on efficient photoinduced hole injection into the NiO valence band. A system of a mesoporous NiO film co-sensitized with CdSe QDs and a molecular protonreduction catalyst was studied. While successful electron transfer from the excited QDs to the catalyst is observed, most of the photogenerated holes are instead quenched very rapidly (ps) by ho...

7 Carbon nanotubes have been intensively researched for electronic applications, driven 8 by their excellent electronic properties, with the goals being control and 9 reproducibility of growth, semiconducting/metallic type selectivity and maintaining 10 high quality of carbon nanotubes, in a process that is temperature-compatible with the 11 electronics. Photo-thermal chemical vapour deposition...

One of the main challenges for using microbial fuel cells (MFCs) is developing materials and architectures that are economical and generate high power densities. The performance of two cathodes constructed from two low-cost anion (AEM) and cation (CEM) exchange membranes was compared to that achieved using an ultrafiltration (UF) cathode, when the membranes were made electrically conductive usi...

A three-component process for the one-pot synthesis of 6-amino-4-aryl-5-cyano-3-methyl-1-phenyl-1,4-dihydropyrano[2,3-c]pyrazoles is described by the three-component reaction of aldehydes, 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one and malononitrile in the presence of Fe3O4@FSM-16-SO3H as an efficient magnetically recyclable mesoporous catalyst. Folded shee...

The activity of a Te-MgO catalyst prepared by adsorbing Te vapor onto MgO powder was determined by dehydrogenation of indane, 9,10-dihydrophenanthrene, cumene, and p-cymene. The activity of the Te-MgO catalyst was higher than that of the MgO catalyst in most of the cases investigated. The selectivity of the former catalyst was much higher than that of the later in all cases studied. The Te-MgO ...

To begin to build an understanding of the interactions of CYP2B6 with substrates, two different 3-dimensional quantitative structure activity relationship (3D-QSAR) models were constructed using 16 substrates of B-lymphoblastoid expressed CYP2B6. A pharmacophore model was built using the program Catalyst, which was compared with a partial least-squares (PLS) model using molecular surface-weight...

A new catalyst derived from osmium has been prepared, fully characterized and tested in the dihydroxylation of alkenes. The catalyst was prepared by wet impregnation methodology of OsCl3•3H2O on a commercial micro-magnetite surface. The catalyst allowed the reaction with one of the lowest osmium loadings for a heterogeneous catalyst and was selective for the monodihydroxylation of 1,5-dienes. M...

12 The activities of copper oxide supported on mesoporous alumina and manganese oxide 13 have been investigated for nitric oxide (NO) reduction using carbon monoxide (CO) as 14 reducing agent. The results showed that catalytic activity is strongly influenced by the 15 properties of supports. CuO supported on manganese oxide was found to be a more 16 active catalyst for the NO reduction as compa...
