Panchromatic ruthenium sensitizer based on electron-rich heteroarylvinylene pi-conjugated quaterpyridine for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Filippo de Angelis

The first example of a heteroarylvinylene pi-conjugated quaterpyridine Ru(II) sensitizer (N1044) was synthesized and used in dye-sensitized solar cells; the dye has an effective panchromatic absorption band, covering the entire visible spectrum up to the N ...

Vibrational properties of vitreous GeSe2 with the Becke-Lee-Yang-Parr density functional

Alfredo Pasquarello, Carlo Massobrio, Luigi Giacomazzi

The vibrational properties of vitreous GeSe2 are studied within the Becke-Lee-Yang-Parr (BLYP) generalized gradient approximation to density functional theory. For this purpose, we consider two models. The first one is derived from a chemically ordered net ...

Analyzing Near-infrared Images for Utility Assessment

Sabine Süsstrunk, Zahra Sadeghipoor Kermani, Neda Salamati

Visual cognition is of significant importance in certain imaging applications, such as security and surveillance. In these applications, an important issue is to determine the cognition threshold, which is the maximum distortion level that can be applied t ...

High-Power 1.48-μm Wafer-Fused Optically Pumped Semiconductor Disk Laser

Elyahou Kapon, Vladimir Iakovlev, Alexei Sirbu

An output power up to 5 W at 1.48- m wavelength is achieved from an optically pumped semiconductor disk laser. An active region composed of an AlGaInAs/InP heterostructure grown on an InP substrate was wafer fused with an AlGaAs/GaAs Bragg reflector grown ...

Metallic Nanodot Arrays by Stencil Lithography for Plasmonic Biosensing Applications

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Oscar Vazquez Mena

The fabrication of gold nanodots by stencil lithography and its application for optical biosensing based on localized surface plasmon resonance are presented. Arrays of 50−200 nm wide nanodots with different spacing of 50−300 nm are fabricated without any ...

Recombination coefficients of GaN-based laser diodes

Nicolas Grandjean, Jean-François Carlin, Julien Dorsaz, Luca Alex Milo Sulmoni

We measure the charge carrier recombination coefficients of InGaN quantum wells by analyzing the dynamical properties of (Al,In)GaN laser diodes emitting in the violet spectral range. Relaxation oscillations and turn-on delays are fitted to a rate equation ...

Single crystal nuclear magnetic resonance in spinning powders

David Lyndon Emsley

We present a method for selectively exciting nuclear magnetic resonances (NMRs) from well-defined subsets of crystallites from a powdered sample under magic angle spinning. Magic angle spinning induces a time dependence in the anisotropic interactions, whi ...

Anticancer activity of osmium metalla-rectangles

Paul Joseph Dyson, Fabio Edafe

A series of cationic metalla-rectangles of the general formula [(p-cymene)4Os4(OO.intrsec.OO)2(N.intrsec.N)2]4+ have been obtained in methanol from the dinuclear arene osmium precursors [(p-cymene)2Os2(OO.intrsec.OO)2Cl2] (OO.intrsec.OO = 2,5-dihydroxy-1,4 ...
