Providing heat pumps for the retrofit of fuel based boilers in residential heating, is a short or medium term challenge and a major opportunity for a substantial reduction of greenhouse gas emissions. While effective solutions for improved high temperature ...
Important land surface characteristics affect the way in which water is transferred to the atmosphere, processed in the atmosphere, and eventually returned to the surface. In turn, the amount of water in the atmosphere and returning to Earth affects many o ...
Global climate change mitigation policies call for increasing use of biomass fuels as renewable substitutes to fossil energy resources. Quantified targets for biofuels introduction in to the market exist in the United States, the European Union, and a numb ...
The reductive transformation of the 10 most-widely distributed fluorinated volatile compounds and of tetrachloroethene was investigated for up to 177 days under anaerobic conditions in sewage sludge and aquifer sediment slurries. Concentrations of parent c ...
This PhD thesis presents the development of a methodological framework to analyse potential climate change impacts on a high mountainous water resources system and to quantify the associated modelling uncertainties. The main objective is to show whether st ...
This article presents state-of-the-art atmospheric methane reconstruction based on ice-core studies. Starting with a biogeochemical overview of the methane cycle, it also introduces the processes of gas diffusion in firn and trapping in ice. It presents an ...
The impact of human activities on the global climate may lead to large disruptions of the economic, social and political status quo in the middle and long term. Understanding the dynamics of the Earth's climate is thus of paramount importance and one of th ...
Besides providing a more efficient energy use, a large scale application of solar energy technologies in the urban context will be required in the upcoming decades to achieve a drastic reduction of greenhouse gas emissions in the biosphere. Three different ...
Greenhouse gas measurements along polar ice cores provide important insight into the former composition of the atmosphere, its natural variations, and the responses to fast climatic changes in the past. We present high-resolution nitrous oxide (N2O) and me ...
We report a recent breakthrough to control profile angle for SiO2 Deep Anisotropic Dry Etching (SDADE). Our study reveals that gas residence time is the key parameter to control profile angle. Moreover, we show that it is possible to control profile angle, ...
