How much room is left for European gas incumbents?

In the context of the liberalization of the European natural gas market former monopolists face a challenge to react to market opening by realigning their strategies. Three major groups of companies can be identified that are capable to influence the Europ ...

Plasma silane concentration as a determining factor for the transition from amorphous to microcrystalline silicon in SiH4/H-2 discharges

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Benjamin Strahm

In this work, the microstructure transition from amorphous to microcrystalline silicon is defined in terms of the silane concentration in the plasma as opposed to the silane concentration in the input gas flow. In situ Fourier transform infrared absorption ...

Microcrystalline silicon deposited at high rate on large areas from pure silane with efficient gas utilization

Christophe Ballif, Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Benjamin Strahm

Microcrystalline silicon thin film deposited by RF-PECVD and integrated in a tandem structure is a promising material for low cost photovoltaic solar cells compared to solar cells based on crystalline silicon. However, in order to allow a cost-effective ma ...

Important New Nodes; Gas Hubs and their Impact on Competition

Bastian Wolfgang Schwark

Although the gas market in the European Union was opened up with two major directives in 1998 and 2003, competition in Europe is still developing slowly. One major cause is the insufficient availability of gas that is not contracted by long-term contracts ...

The Impact of Surplus Sharing on the Stability of International Climate Agreements

Juan Carlos Altamirano Cabrera

This paper analyses stability of coalitions for greenhouse gas abatement under different sharing rules applied to the gains from cooperation. We use a 12-region model to examine internal and external stability of coalitions. We determine and compare stable ...

Gas viscosity sensor

Peter Ryser, Sigfrid Straessler

A gas viscosity sensor comprises a signal processing circuit and a sensor element, including a gas pressure generating system and a differential pressure measuring system in fluid communication therewith, the differential pressure measuring system comprisi ...

Numerical simulation of free surface incompressible liquid flows surrounded by compressible gas

Jacques Rappaz, Marco Picasso, Alexandre Caboussat

A numerical model for the three-dimensional simulation of liquid-gas flows with free surfaces is presented. The incompressible Navier-Stokes equations are assumed to hold in the liquid domain. In the gas domain, the velocity is disregarded, the pressure is ...

The Effect of Membership Rules and Voting Schemes on the Success of International Climate Agreements

Juan Carlos Altamirano Cabrera

We empirically test the role of membership rules and voting schemes for climate change coalitions with the STAbility of COalitions model (STACO). The model comprises twelve world regions and captures long-run effects of greenhouse gas accumulation. We appl ...

Rapid climate variability during warm and cold periods in polar regions and Europe [Variabilité climatique rapide pendant les périodes chaudes et froides aux pôles et en Europe]

Jérôme Chappellaz

Isotopic mass spectrometry coupled online with gas chromatography (GC-C-IRMS) permits measurement of relative proportions of gaseous hydrocarbon (CH4 to C4H10) and CO2, and determination of carbon isotope ratio of hydrocarbon molecules. Access to these par ...

Semi-continuous PM2.5 inorganic composition measurements during the Pittsburgh air quality study

Satoshi Takahama

A method for semi-continuous (10 min time resolution) PM2.5 nitrate and sulfate measurements, based on the humidified impaction with flash volatilization design of Stolzenburg and Hering (Environ. Sci. Technol. 34 (2000) 907), was evaluated during the Pitt ...
