Today, much of world’s consumed energy is lost to waste heat through all levels of human activity. For example, thermal loss consists 20 to 50 % of total energy consumption across different industrial sectors and as high as 60-70% in current gasoline and/or diesel powered. If even a small fraction of ‘waste-heat’ could be converted into more useful forms of energy (e.g., electrical, mechanical, etc.), it would result in tremendous savings to global energy consumption.
In the MAGENTA H2020 project (MAGnetic nanoparticle based liquid ENergy materials for Thermoelectric device Applications), we are developing brand new thermoelectric materials based on ionic ferrofluids; i.e., colloidal dispersions of magnetic nanoparticles in ionic liquids. It is an inter-disciplinary and cross-sector R&D project combining concepts and techniques from physics, chemistry and electrochemistry with an active participation from industrial partners. As its final products, MAGENTA will offer novel liquid thermoelectric materials that are versatile, cost-effective and non-toxic to assist the economically and environmentally sustainable energy transition in Europe.
Nuclear Magnetic Resonance is a powerful analytical tool that allows a wide variety of studies of matter, in all its forms. It involves very low energies and combines multi-scale properties for atomic and molecular analysis as well as macroscopic analysis of deep tissues. It suffers mainly from two defects: its lack of sensitivity and its inability to study large objects in a high magnetic field.
The acquisition of an NMR spectrometer/imager with a large cavity magnet will let more place in a high magnetic field and opens up new perspectives, such as:
