AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The main characteristics of water management in Switzerland are its big diversity, strong decentralisation, and different modes of management between drinking water supply and sanitation. Both, the distribution of water and sanitation, fall within the comp ...
The crystal structure of a strontium-imidazolium polymeric material obtained from the reaction of zwitterionic 1,3-bis(carboxymethyl)-imidazolium with SrCO3 (2:1) in water is reported. The compound crystallized in the orthorhombic space group Pcc2 with a = ...
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 ...
The obtimisation of water networks in a deinking mill has been carried out using Mixed Integer Non Linear Programming. The objective function included the costs of water and chemical usage, and of piping retrofitting. The constraints were stream compositio ...
We report the filling kinetics of different liquids in nanofabricated capillaries with rectangular cross-section by capillary force. Three sets of channels with different geometry were employed for the experiments. The smallest dimension of the channel cro ...
The dye coumarin 343 (C343) adsorbed on the surface of ZrO2 nanoparticles in aq. solns. was used to study the solvation dynamics close to these surfaces. The time-resolved Stokes shift was measured by femtosecond frequency-resolved upconversion. The absorp ...
The intensity of water absorption in the region of the solar spectrum plays a dominant role in atmospheric energy balance and hence strongly influences climate. Significant controversy exists over how to model this absorption accurately. We report dipole m ...
Polypeptide secondary structure controls the dimensions of aggregates formed from a polybutadieneb-poly(L-glutamic acid) diblock copolymer after direct dissolution into water. The hydrodynamic radius (RH) of these aggregates (even at high NaCl concentratio ...
Observations made from vertical moorings of thermistors and current meters are used to analyze the relative contribution of the entrainment of overlying water and the cold plumes convecting from the surface to the cascade of dense shelf waters down the sid ...

The deactivation kinetics of a V/Ti oxide catalyst were studied in partial oxidn. of toluene to PhCHO and PhCO2H at 523-573 K. The catalyst consists of a monolayer of VOx species, and after oxidative pretreatment, contains isolated monomeric and polymeric ...
