Studies of coupled charge transport in dye-sensitized solar cells using a numerical simulation tool

Ulf Anders Hagfeldt

In this paper, we present a simulation platform designed to study coupled charge transport in dye-sensitized solar cell (DSC) devices. The platform, SLICE, is used to study the influence of ions in the electrolyte on electron transport in the nanoporous me ...

Stratégies aéroportuaires en Suisse

Tristan Chevroulet, Aymeric Sevestre

Airport operation in Switzerland is confided to companies with private law status. The Federal Ministry has drawn up a sectoral Plan of air infrastructure, which is an instrument both of regional policy and of planning. It does not create new rights but fi ...

A new solution for increasing the efficiency of an electric scooter with supercapacitors through a novel, interleaved multi-channel DC/DC converter

Alfred Rufer, Philippe Barrade, Blaise Destraz

Scooters are a well-established transport system for short distances – particularly within cities. Currently, the majority of scooters are petrol powered. Their engines typically exhibit bad efficiencies and thus contribute to global warming by CO2 product ...

Pumping of mammalian cells with a nozzle-diffuser micropump

Martinus Gijs, Horst Vogel, Caroline Vandevyver, Christophe Yamahata, Frédéric Lacharme, Paulina Izewska

We discuss the successful transport of jurkat cells and 5D10 hybridoma cells using a reciprocating micropump with nozzle-diffuser elements. The effect of the pumping action on cell viability and proliferation, as well as on the damaging of cellular membran ...

Strategic evolution of railway corridors infrastructure: dual approach for assessing capacity investments and M&R strategies

Yves Putallaz

Political trends as well as general growth of the transport market set new challenges to railways and particularly to rail infrastructure managers. Rail infrastructure must become more efficient, which is to say that costs must be reduced and the use of ca ...

Double-fed asynchronous motor-generator equipped with a 3-level VSI cascade

Jean-Jacques Simond, André Hodder, Alexander Schwery

The present paper investigates the complete regulation strategy for a large double-fed asynchronous motor-generator equipped with a 3-level VSI cascade for applications mainly in the field of pumped storage plant. For the present application, the specific ...

Sea Change in Rail Freight Practice

Tristan Chevroulet

During the past ten years, freight transport volume increased by 30 percent in the European Union, whereas road increased by 38 per cent. One can therefore not be very optimistic about rail freight. Not only has rail freight stagnated during that period, b ...
