Geological repository for highly radioactive waste disposal is a system of engineered and natural barriers. The objective of this system is to contain and isolate waste and protect the environment and humans from ionizing radiation. For the evaluation of performance of engineered ... En savoir plus
Modelling of Interfacial Charges and Kinetics of Dye-Sensitized Solar Cells Photoanodes
In this study, we attempted to develop a simulation to better understand the kinetic of the dye regeneration process in photoanodes of dye-sensitized solar cells (DSSCs). For that purpose, a numerical model was developed using finite element simulation in COMSOL Multiphysics®. The ... En savoir plus
Numerical Modeling of Bentonite Erosion due to Sedimentation in Sloping Fractures
The study of bentonite erosion mechanisms in fractures is a problem of maximum interest to understand the long-term performance of the engineered barrier in deep geological repositories of spent nuclear fuel. In this context, erosion due to shear by seeping water, sedimentation due to ... En savoir plus
Proton Enrichment and Surface Charge Dynamics in pH-Responsive Nanopores
The acid-disassociation of surface groups generates the surface charge that drives fundamental nanoscale ion transport behaviors, such as ion current rectification in nanopores. Ion current rectification can be utilized for high sensitivity label-free sensors. The disassociation of ... En savoir plus
Reinforcement Bars Corrosion in a Carbonated Concrete
In the construction sector, the concrete and the steel bars represent still the key components, although they are very vulnerable by the atmospheric agents, as in the case of their degradation caused by corrosion. The value of the concrete carbonation may enhance the corrosion around the ... En savoir plus
Release of the Model Substance Through the Polymer Membrane into the Biological Environment
Currently, there is a great interest in the study of gels, especially their transport or release properties. Hydrogels have countless definitions, but generally speaking, they are hydrophilic systems with a three-dimensional structure that tend to swell and hold large amounts of water ... En savoir plus
