The aim of this study was to determine the difference in disinfection between aggregated and dispersed virus. Bacteriophage MS2 was chosen as a surrogate for enteric virus. The first part of this project consisted of characterizing the aggregation of MS2 a ...
A one-step extrusion process under physiological conditions yielded calcium alginate-poly-(ethylene glycol) hybrid microspheres (Alg-PEG-M), for which the physical properties were adjustable by the macromolecular characteristics of the components, their co ...
Hydrogenation of bicarbonates in water: By using a ruthenium-based catalytic system hydrogenation of sodium bicarbonate was achieved in water in comparable high TONs and yields. The hydrogenation of sodium bicarbonate takes place with the catalytic system ...
In this work, molecular simulations were performed to evaluate the separation performance of two typical zeolitic imidazolate frameworks (ZIFs), ZIF-68 and ZIF-69, for CO2/N2, CO2/CH 4, and CH4/N2 mixtures. To do this, we first identified a suitable force ...
A fertilisation experiment was started in the French Alps on an acid grassland at 2000 m in 1989 where lime as calcium carbonate ("liming") and Thomas Slag enriched by potassium chloride ("fertilisation") were added in a random block design until 1992. Sin ...
Adsorption of N-2 at 77 K and scanning electron microscopy have been used to measure the changes in the support morphology, at nano- and microscale level, along the processes involved in the preparation of a supported Pd catalyst: Pd deposition, doping, an ...
Thermodynamic solubility calculations are normally only related to thermodynamic equilibria in solution. In this paper, we extend the use of such solubility calculations to help elucidate possible precipitation reaction pathways during the entire reaction. ...
Using calculations based on density-functional theory, we explore the configurations that water molecules (2,3,4;6) assume on the surface a sodium 2:1 smectite clay with isomorphic substitutions both on octahedral and tetrahedral sheets. The hydrophilicity ...
Lack of improved drinking water sources contributes a lot to many waterborne diseases caused by pathogens which include viruses, protozoa, bacteria or worms. It is essential to develop and promote treatment methods in order to provide pathogen-free safe dr ...
We present a new aerosol microphysics and gas aerosol partitioning submodel (Global Modal-aerosol eXtension, GMXe) implemented within the ECHAM/MESSy Atmospheric Chemistry model (EMAC, version 1.8). The submodel is computationally efficient and is suitable ...
