Geological heterogeneity in landslides

Significant progress has been made these last decades in the development of hydrogeological numerical flow modelling for describing the hydrodynamic behaviour of landslides. However, these new sophisticated methods are still very seldom used in the problem ...

Improved Photon-to-Current Conversion Efficiency with a Nanoporous p-Type NiO Electrode by the Use of a Sensitizer-Acceptor Dyad

Ulf Anders Hagfeldt

A perylene imide sensitizer and a covalently-linked perylene imide-naphthalene diimide dyad were prepd. and characterized by absorption and emission spectroscopies, electrochem., and spectroelectrochem. These compds. were chemisorbed on nanoporous Ni oxide ...

A new strategy of molecular overcharge protection shuttles for lithium ion batteries

Michael Graetzel, Shaik Mohammed Zakeeruddin

The conventional strategy of overcharge protection for lithium ion batteries uses redox molecules having oxidation potential higher than the cathodic materials in the electrolyte. Here we propose a novel approach by using redox molecules having reduction p ...

SECM photography

Hubert Girault, Fernando Cortes Salazar, Bin Su, Mohamad Hojeij

A novel strategy for imaging commercial black-and-white negative photo films by scanning electrochemical microscopy (SECM) is demonstrated. The imaging is based on using IrCl3 6 as the redox mediator to dissolve silver grains. The SECM probe is biased at a ...

Photoinduced absorption spectroscopy as a tool in the study of dye-sensitized solar cells

Ulf Anders Hagfeldt

Photoinduced absorption spectroscopy, where the excitation is provided by a square-wave modulated (on/off) monochromatic light source, is a versatile tool in the study of dye-sensitized solar cells. Spectra of transient species, such as the oxidized dye, c ...

A new implantable device for telemetric control of pulmonary blood flow

Nikolaos Stergiopoulos

The main problem encountered in pulmonary artery banding is the difficulty in determining the optimal perimeter of the band, and sometime repeated surgical operations are required to adjust the band perimeter in order to control the pulmonary blood flow. T ...

A possible role of radial electric field in driving parallel ion flow in scrape-off layer of divertor tokamaks

Richard Pitts, Marco Wischmeier, Heinz Mueller

The radial electric field in known to be one of the drivers of parallel ion flow in the SOL. It contributes to the ion Pfirsch-Schluter flow and also determines the 'return parallel flow' that can arise to compensate poloidal E x B drift. It was establishe ...
