    • Offer for a Thesis Allowance (or a Post-doc position)Subject: Mercury speciation in bacteria cells combining analytical techniques

      Mercury (Hg) is a persistent pollutant in the environment, highly volatile and able to convertinto highly toxic methylmercury (MeHg). MeHg is a serious threat as it is a neurotoxic compound, which is bioaccumulated and bioamplified in food webs. Bacteria play a central role in MeHg conversionbut thisHg biomethylationcannot be fully explained. To better understand these processes, it is necessary to have a clear view of the Hg species available and released by bacteria. The present offer proposes to tackle Hg speciationcombining analytical techniques based on mass spectrometry. Our team at IPREM lab aims to characterize Hg trafficking andmethylationin sulphate-reducing bacteria (SRB) comparing strains able to both methylate and demethylate mercury and strains only able to demethylate methylmercury. The objective of this workis set up analytical methods(GC-ICPMS, LC-MS...) to identify and quantify Hg species and to determine Hg speciation in different bacterial cultures depending on various mercury exposures. The role of thiol ligands is particularly focused.

    • Offer for a Thesis AllowanceSubject: HYdrogen storaGe in Innovative hybrid matErials

      The development of hydrogen as a new energy carrier requires to store it under acceptable energeticand safety conditions, particularly in the context of large-scale, long-term stationary storage of electricity converted by electrolysis into hydrogen. Different types of hydrogen storageexist: storage in conventional reservoirs (in gaseous or liquid state) and storage in solids (as anadsorbed, absorbed or trapped phase). None of these techniques is, to date, totally satisfactory for the intended application. The objective of this thesis is to propose, characterize and test under field conditions two innovative hybrid materials for the storage of hydrogen.Each of this hybrid material containsa phase-change material (complex metal hydride or organic molecular crystal) confined within a porous matrix (carbon xerogel) having a double porosity. The phase change materials will be inserted into the storage nanoporosity so that they can capture hydrogen under acceptable temperature and pressure conditions by shifting the thermodynamic equilibria. The transport of hydrogen to the storage porosity will be ensured by the transport porosity, which will promote the kinetics of capture / release.
