In order to meet demands for crops, pasture and firewood, the rate of land use change from forested to agricultural uses steadily increased over several decades, resulting in an increased release of nutrients towards groundwater and surface water bodies. I ...
A new transformation based on the Staudinger reaction is described, and its application in the design of a novel switch element to control peptide folding is demonstrated. We found that the azide switch is activated rapidly in water to promote acyl transfe ...
Time resolved optical Kerr effect measurements have been used to det. the orientational dynamics of water in the pores of ZrO2 nanostructured films. We demonstrate that local heating effects can safely be ignored and present our results which are manifestl ...
A new concept of road runoff management, based on diffuse infiltration over the shoulder, was tested in a real-scale experimentation site located near Grandson, Switzerland. This new concept consists in diffusely infiltrating the road runoff in the infiltr ...
The work presented in this thesis was carried out in the framework of two European projects: SOLWATER, and AQUACAT. The global objective of those projects, including the present work, was to set an autonomous system for drinking water production in develop ...
The gas phase methylation of biphenyl with MeOH over HZSM-5 and HZSM-5 modified with Si(OEt)4 was investigated at atm. pressure in the presence of water. The modification of the outer surface of the catalyst pellets by silicate gives increased selectivity ...
A simple approach to sensor development based on encapsulating a probe molecule in a cellulose support followed by regeneration from an ionic liquid solution is demonstrated here by the codissolution of cellulose and 1-(2-pyridylazo)-2- naphthol in 1-butyl ...
The study was performed in the Sahelian part of Burkina Faso. The country is subject to difficult climatic conditions, a strong demographic growth and a continuous decrease in soil fertility. The resulting degradation affects the processes which govern eco ...
Most natural and engineered soils usually exhibit a state of partial saturation in water. Indeed, fast and heavy water flowing into the soil is known to cause collapse or soil plasticization which may be at the origin of harmful settlements. The mechanical ...
The cyclic undecapeptide cyclosporin A (CsA) has a remarkable spectrum of diverse biological activities, including anti-inflammatory, antifungal, antiparasitic as well as immunosuppressive activities. However, the low water solubility of this drug is a ser ...
