Modeling the Indoor Removal of Volatile Organic Compounds (VOCs) by Botanical Biofiltration

Allan A. Alvarado-Alvarado1, S. Denys1
1Sustainable Energy, Air and Water Technology Research Group (DuEL), Department of Bioscience Engineering, University of Antwerp, Antwerp, Belgium

Historically, indoor air quality (IAQ) has received less attention than outdoors, although people spend >90% of their time in the indoor environment. A major group of indoor air pollutants is volatile organic compounds (VOCs), which are detrimental to human health even at low ... Read More

Modelling of Desaturation/Resaturation of Geological Repository Barriers Considering Gas Generation

A. Narkuniene1, P. Poskas1, R. Kilda1
1Lithuanian Energy Institute, Kaunas, Lithuania

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 ... Read More

Modelling of Interfacial Charges and Kinetics of Dye-Sensitized Solar Cells Photoanodes

Wasiu Abidemi Hamzat1, Dmitry Momontenko1, Gunther Wittstock1
1Chemistry Department, Carl von Ossietzky University of Oldenburg, D-26111, Germany

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 ... Read More

Numerical Modeling of Bentonite Erosion due to Sedimentation in Sloping Fractures

Virginia Cabrera1, Arnau Pont1, Andrés Idiart1, Patrik Sellin2
1Amphos 21 Consulting S.L., Barcelona, Spain
2SKB, Solna, Sweden

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 ... Read More

Proton Enrichment and Surface Charge Dynamics in pH-Responsive Nanopores

Dominik Duleba1, Robert P. Johnson1
1University College Dublin, Dublin, Ireland

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 ... Read More

Reinforcement Bars Corrosion in a Carbonated Concrete

Bruno Chiné1, Ronald Jiménez Salas1, Rommel Cuevas Kauffmann2
1School of Materials Science and Engineering, Costa Rica Institute of Technology Cartago, Costa Rica
2School of Construction Engineering, Costa Rica Institute of Technology Cartago, Costa Rica

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 ... Read More

Release of the Model Substance Through the Polymer Membrane into the Biological Environment

Darya Zhurauliova 1, Miloslav Pekar1
1Faculty of Chemistry, Brno University of Technology, Brno, CZ

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 ... Read More
