Ligand Engineering for the Efficient Dye-Sensitized Solar Cells with Ruthenium Sensitizers and Cobalt Electrolytes

Mohammad Khaja Nazeeruddin, Jacques-Edouard Moser, Peng Gao, Filippo de Angelis, Thomas Moehl, Joël Teuscher, Aswani Yella, Sadig Aghazada, Gabriele Marotta

Over the past 20 years, ruthenium(II)-based dyes have played a pivotal role in turning dye-sensitized solar cells (DSCs) into a mature technology for the third generation of photovoltaics. However, the classic I3−/I− redox couple limits the performance and ...

Microalloying for the controllable delay of precipitate formation in metal alloys

William Curtin, Michael Frederick Francis

A model is presented to predict the effectiveness of dilute solutes in delaying precipitate formation, with application to natural and artificial aging in metal alloys. Control of aging is achieved via the binding, at natural aging temperatures, and releas ...

Anticancer Organometallic Osmium(II)-p-cymene Complexes

Paul Joseph Dyson, Rosario Scopelliti, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Osmium compounds are attracting increasing attention as potential anticancer drugs. In this context, a series of bifunctional organometallic osmium(II)-p-cymene complexes functionalized with alkyl or perfluoroalkyl groups were prepared and screened for the ...

Higher generation cationic N,N-ruthenium(II)-ethylene-glycol-derived metallodendrimers: Synthesis, characterization and cytotoxicity

Paul Joseph Dyson, Tina Riedel

A new series of higher generation cationic N,N-chelating, ruthenium(II)-ethylene-glycol metallodendrimers from first-, second-, third- and fourth-generation pyridylimine-based poly(propylene) dendrimer scaffolds of the type, DAB-(NH2) (where n = 4, 8, 16 o ...

Homogenous catalytic hydrogenation of bicarbonate with water soluble aryl phosphine ligands

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis

The chemical transformation of CO2 and bicarbonates into useful products becomes increasingly impor- tant as the atmospheric CO2 level has reached 400 ppm. Here a small library of sulfonated aryl mono- phosphines and aryl diphosphines was tested as stabili ...

In vivo evaluation of small-molecule thermoresponsive anticancer drugs potentiated by hyperthermia

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Hyperthermia used as an adjuvant with chemotherapy is highly promising in the treatment of certain cancers. Currently, the small molecule drugs used in combination with hyperthermia were not designed for this application. Herein, we report the evaluation o ...

Fabrication of CMOS-compatible abrupt electronic switches based on vanadium dioxide

Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Wolfgang Amadeus Vitale, Antonio Paone

Vanadium dioxide thin films were deposited on amorphous SiO2-coated Si substrates, by reactive magnetron sputtering at 490 °C of a pure vanadium target. The deposition parameters were optimized in order to maximize the resistivity modulation due to the met ...

Formic Acid Dehydrogenation Catalysed by Tris(TPPTS) Ruthenium Species: Mechanism of the Initial "Fast" Cycle

Gabor Laurenczy, Andrew Francis Dalebrook, Arnaud Thevenon, Ewan Patrick Frost-Pennington

Water-soluble ruthenium m-triphenylphosphinetrisulfonate (TPPTS) complexes are excellent catalysts for formic acid dehydrogenation. Interestingly, the choice of metal catalyst precursor has a direct influence on initial activities. The reaction with hexaaq ...

Ligand substitutions between ruthenium-cymene compounds can control protein versus DNA targeting and anticancer activity

Paul Joseph Dyson, Ursula Röthlisberger, Wee Han Ang, Alexey Nazarov, Pablo Campomanes Ramos, Catherine Marie Amélie Clavel, Michael Groessl

Ruthenium compounds have become promising alternatives to platinum drugs by displaying specific activities against different cancers and favourable toxicity and clearance properties. Nonetheless, their molecular targeting and mechanism of action are poorly ...
