Effect of alkaline conditions on near-field processes of a spent nuclear fuel geological repository
The contact ofthe spent nuclear fuel (SNF) with water dueto a failure in the canister would be a conservative but still plausible hypothesis in the safety assesment of a deep geologic repository (DGR). Concrete and ...
Characterization and modelling of micro and nanofluidic systems
Lab-on-a-chip arrangements are ever more frequently used for the miniaturization of chemical and biochemical analysis. In these arrangements, all the manipulations of analyte transport, separation, mixing with reactants ...
Removal of boron from aqueous solutions using biopolymers and composites
The growing concern over environmental pollution in recent decades has placed increasing focus on research into the development of sustainable processes associated with the removal of contaminants in waters. Water is scarcer ...
Electron transfer processes in biomimetic membranes incorporating prenylquinones
The photosynthesis is the process used by the plants and bacteria cells to convert the inorganic matter in organic thanks to the light energy. This process consist on several steps, being one of them the plastoquinone-9 ...
Antioxidant properties of extracts from selected plant materials (Caesalpinia spinosa, Perilla frutescens, Artemisia annua and Viola wittrockiana) in vitro and in model food systems
Phenolic compounds, ubiquitous in plants, are of considerable interest and are increasingly becoming a subject of intensive research due to their bioactive properties such as antioxidant, antimicrobial, anti-mutagenic, ...
Complexation of Th(IV) and U(VI) by polyhydroxy and polyamino carboxylic acids
