1. Characterization of non-aqueous phase liquid sources in porous media : significance of physical and chemical heterogeneity
Abstract : .... READ MORE

2. Experimental and Modelling Studies on the Spreading of Non-Aqueous Phase Liquids in Heterogeneous Media
Abstract : Non-Aqueous Phase Liquids (NAPLs) include commonly occurring organic contaminants such as gasoline, diesel fuel and chlorinated solvents. When released to subsurface environments their spreading is a complex process of multi-component, multi-phase flow. READ MORE

3. Hydrogeological modeling to improve remediation strategies for a drinking water aquifer contaminated by an aqueous phase liquid
Abstract : In many communities, groundwater is an important source of drinking water. Groundwater aquifers are, however, vulnerable to the widespread and increasing problem of contamination from anthropogenic sources. Once in the groundwater, contaminants are likely to remain there for a long time as the attenuation rate is slow. READ MORE

4. Multiphase Contamination in Rock Fractures : Fluid Displacement and Interphase Mass Transfer
Abstract : Multiphase flow and transport in fractured rock is of importance to many practical and engineering applications. In the field of groundwater hydrology an issue of significant environmental concern is the release of dense non-aqueous phase liquids (DNAPLs) which can cause long-term groundwater contamination in fractured aquifers.

5. Solvent Extraction Studies with Substituted Malonamides and Oligopyridines Influence of Structure and Chemical Properties on the Extraction Ability of Trivalent Actinides and Lanthanides
Abstract : Separation and transmutation of spent nuclear fuel has been considered as a complement to direct disposal in a deep geological repository. The time needed for the waste to decay to natural background levels can be drastically decreased if the long-lived radionuclides, mainly the actinides, in the spent nuclear fuel are separated and transmuted to short-lived or stable nuclides.
