Characterization of the metallo-cofactors of the tetrachloroethene reductive dehalogenase purified from Sulfurospirillum multivorans

Sulfurospirillum multivorans is an epsilonproteobacterium able to grow anaerobically with hydrogen as electron donor and tetrachloroethene (PCE) as terminal electron acceptor (organohalide respiration). The dechlorination is mediated by the PCE reductive d ...

Understanding adsorption processes in MOFs through structure and dynamics measurements

Wendy Lee Queen

The development of nanostructured materials with predictable and controllable connectivity and functionalities has sparked a multitude of research directions. We have been studying emerging metal-org. framework (MOFs) systems aimed at applications that ben ...

Understanding adsorption processes in MOFs through structure and dynamics measurements

Wendy Lee Queen

The article describes the use of neutron scattering methods (including powder diffraction, vibrational and rotational spectroscopy, and quasi-elastic scattering) to enhance our understanding of the performance (or lack of performance) of novel storage and ...

Photoinduced Interfacial Electron Injection Dynamics in Dye-Sensitized Solar Cells under Photovoltaic Operating Conditions

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Jean-David Décoppet, Joël Teuscher, Angela Punzi

We report a pump–probe spectroscopy study of electron injection rates in dye-sensitized solar cell (DSSC) devices. We examine the case of working devices employing an N719 ruthenium sensitizer and an iodide electrolyte. Electron injection is found to occur ...

A femtosecond fluorescence study of vibrational relaxation and cooling dynamics of UV dyes

Majed Chergui, Andrea Cannizzo, Thomas James Penfold

We present a femtosecond broad-band fluorescence up-conversion study of the vibrational relaxation dynamics of two UV chromophores, 2,5-diphenyloxazole (PPO) and para-terphenyl (pTP), pumped with a large excess of vibrational energy (>2000 cm(-1)). The ban ...

Characterization of cationic liposomes. Influence of the bilayer composition on the kinetics of the liposome breakdown

The cationic large unilamellar mixed liposomes from 1-palmitoyl-2-oleoyl-phosphatidylcholine (POPC) and didodecyldimethylammonium bromide (DDAB) or dioctadecyldimethylammonium bromide (DODAB) were prepared. The influence of the addition of Triton X-100 (TX ...

Fully-integrated CMOS Probes for Magnetic Resonance Applications

Jens Anders

Techniques based on spin resonance effects are amongst the most powerful analytical methods in both modern chemistry and medicine. Recent years have seen a trend toward scaled-down detection coils, exploiting the fact that a reduction of the detector size ...

Advanced techniques for all-electrical spectroscopy on spin caloric phenomena

Dirk Grundler

Spin-dependent properties of nanomagnets and magnetic/nonmagnetic hybrid systems have gained a renewed interest after the discovery of spin caloric transport phenomena. To explore such properties in detail, advanced techniques need to be developed. In this ...

Towards a more reliable symmetry determination from powder diffraction: a redetermination of the low-temperature structure of 4-methylpyridine-N-oxide

The low-temperature structure of 4-methylpyridine-N-oxide was previously determined in symmetry P4(1) [Damay et al. (2006), Acta Cryst. B62, 627-633]. Using a recently published symmetry-determination method it was found that the true symmetry of the struc ...

Frequency dependent dielectric and mechanical behaviour of elastomers for actuator applications

Yves Leterrier, John Christopher Plummer, Frank Nüesch, Martin Molberg

The low frequency mechanical and dielectric behavior of three different elastomers has been investigated by dynamic mechanical analysis and dielectric spectroscopy, with the aim of accounting for the frequency dependence of the characteristics of the corre ...
