1. Multi-Scale Surface Water-Groundwater Interaction : Implications for GroundwaterDischarge Patterns
Abstract : Rivers and aquifers are continuously exchanging water, driven by processes that occur on various temporal and spatial scales, ranging from small streambed features to large geological structures. The interaction between these two components occurs in permeable sediments below the stream channel, called the hyporheic zone. READ MORE

2. Noise emissions from sustainable transport : A multi-scale modeling approach
Abstract : Noise emissions from transportation remain one of the greatest environmental issues of modern day. Inhabitants in urban environments are especially exposed, with almost 80 million people in the European Union exposed to noise levels exceeding the recommended limits set by the World Health Organization (WHO).

3. On mechanical characterization and multi-scale modeling of Lithium-ion batteries
Abstract : Over the last few decades, rechargeable lithium-ion batteries have been extensively used in portable instruments due to their high energy density and low self-discharge rate. Recently, lithium-ion batteries have emerged as the most promising candidate for electric vehicles and stationary energy storage. READ MORE

4. Novel Multi-Scale Modeling Framework for Structure and Transport in Complex Battery Electrolytes
Abstract : Affordable high energy rechargeable batteries are crucial for further electrification of the transport sector, which is necessary in order to contribute to limit our CO2 emissions to acceptable levels. While today’s lithium-ion batteries (LIBs) have indeed initiated the electrification of the transportation section successfully, electric vehicles are still expensive and typically have ranges limited to ca.

5. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models
Abstract : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance. READ MORE
