A 5-month internship is available in the ANATRAC group at the PhLAM laboratory (Physique des Lasers, Atomes et Molécules), Lille 1 University, France. The Master’s project will focus on investigating the selectivity and trapping/storage properties of clathrates hydrates in sediments with applications to energy storage and fields of geo/astrophysics. Clathrate hydrates are cristalline materials consisting of aqueous cages encapsulating (gaseous) molecular species. The interest for these compounds increased exponentially since their discovery. Originally regarded as simple scientific curiosities, they show now great potential as new natural energy sources. The clathrate solution may address the forthcoming energy crisis and constitute an alternative solution aiming at the reduction of greenhouse gases (ex: CO2) emissions in the atmosphere. Thus, the development of techniques able to trap and store these emissions represents a major challenge to reduce the anthropogenic impact on climate, with the aim of transfering the technology to pre-existing energy plants such as thermal power plants, steel mills, etc. Specifically, this Master’s project focuses on investigating parameters driving clathrates’ formation/dissociation mechanisms and their gas selectivity using thermal desorption and micro-Raman spectroscopy. The candidate should demonstrate clear motivation for experimental work.
