Redox melts formed by copper (i)/(ii) complexes as charge transfer and charge storage materials

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ulf Anders Hagfeldt, Yiming Cao, Marina Freitag, Marko Stojanovic

The present invention relates to a redox copper complex melt comprising a metalorganic complex of formula (I) [Cu (La) n ] (I), wherein n is an integer 2; and La is a bidentate ligand selected from a ligand according to any one of formulae (1) and (2): ...

Improved mechanical dispersion or use of coupling agents? Advantages and disadvantages for the properties of fluoropolymer/ceramic composites

Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche

The aim of this work is to investigate the influence of interfacial chemistry on the properties of fluoropolymer composites, independent of effects derived from changes in morphology, in particular particle dispersion state. A comparative study of solvent ...

Screening method for the onset of bonding of molten polyamide resin layers to continuous fiber reinforced laminate sheets

Martyn Douglas Wakeman

Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...

Iron oxide nanoparticles supported on activated carbon fibers catalyze chemoselective reduction of nitroarenes under mild conditions

Lioubov Kiwi, Duncan Thomas Lindsay Alexander, Oliver Anthony Beswick

Highly dispersed iron oxide (Fe2O3) nanoparticles (NPs) have been immobilized on structured supports of activated carbon fibers (ACF). Systematic catalyst characterizations suggest that ACF-based catalysts remain ultra-microporous after Fe2O3 NPs (similar ...

Window Layers for Silicon Heterojunction Solar Cells

Johannes Peter Seif

Currently, crystalline silicon (c-Si) wafer-based solar cells dominate the photovoltaic market (80-90%). In this thesis we concentrate on silicon heterojunction (SHJ) solar cells that--in contrast to diffused homojunction cells--rely on the application of ...

The Effect of Mg on Slag Reactivity in Blended Cements

Karen Scrivener, Ruben Anton Snellings

Blast-furnace slags are widely used as supplementary cementitious materials in blended cements because of their relatively high reactivity. This study describes the effect of substituting Ca by Mg on the reactivity of synthetic glass with similar compositi ...

Org. ligands (or surfactants) are key in detg. colloidal nanocrystal structure and, therefore, function. In addn. to their more traditional role as surface passivating agents impacting nanocrystal size and shape, surfactants can also behave as active reage ...
