Renewable energy sources such as solar and wind are intermittent in nature. Their effective utilization requires efficient, low cost energy storage systems to complement energy harnessing systems. The rechargeable flow batteries have emerged as the most suitable candidates due to their ... En savoir plus

Climate change and concerns over the reliable supplies of hydrocarbons are aiding in the focus on Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs). The Lithium-ion battery as a better solution for energy storage in automobile applications is briefly introduced. Adverse effects ... En savoir plus

We report the reversible thermoelectric switching [1, 2, 3] induced by a time dependent and frequency domain electric field (or AC voltage) in a microscopic single contact nano-device based on Gold and Vanadium Oxide, which promises potential applications for future information storage ...

Hydrogen storage can be considered as a key factor in the development of hydrogen economy. Hydrogen storage in a magnesium hydride MgH2 is a very promising technique for numerous of reasons. Magnesium is abundant, relatively cheap, life – friendly , weight storage capacity of 7.6% ... En savoir plus

During the manufacturing of CFRP components one of the most critical process steps is the vacuum bagging. In this process several layers of material are draped separately over complex part shapes. The specific properties of each material, which are needed for the process (i. e. breather, ... En savoir plus

Introduction The soluble lead flow battery (SLFB) is a form of redox flow battery (RFB), an electrochemical device where energy is stored in a liquid electrolyte. The electrolyte is pumped around a flow circuit from a reservoir to the cell where redox reactions occur and the energy is ... En savoir plus

To assess the safety deep geological repositories for nuclear waste, it is important to have a clear understanding of groundwater flow at the interface between the storage vault and the fractured rock. Traditional approaches for modelling groundwater often consider both the geological ... En savoir plus

The aim of this research is to contribute with the development of Carbon Capture and Storage techniques by studying carbon dioxide (CO2) adsorption mechanisms in shale reservoirs. Gas desorption is considered a major gas production mechanism and has a relevant role in shale gas ... En savoir plus

Gas shales are one of the potential sinks considered for carbon dioxide sequestration. Therefore further research on the importance of sorption on the carbon dioxide sequestration potential is highly topical. Experimentally measured maximum sorption capacity of carbon dioxide was about ... En savoir plus

In this paper, a numerical study is conducted on the melting and solidification process of metal foam/paraffin wax with cyclic heating and cooling. A mathematical model based on the Brinkman-Frochheimer extended Darcy equation and the local thermal non-equilibrium model (LTNE) is ... En savoir plus
