Post doc position at LCMCP(Paris) in PFG-NMR

We have an opening for an 18 months postdoc to join our group at Laboratoire de Chimie de la Matière Condensée de Paris (LCMCP), part of Sorbonne Université (Paris). The applicant will use PFG-NMR to study transport and adsorption in multiscale porous materials in the framework of an ANR-funded project that combines the synthesis, characterization and modelling skills of four partner labs in France.

Porous materials are at the heart of key applications:

chemistry/chemical engineering, energy, environment and Earth science.

Among porous solids, microporous materials (< 2 nm) such as zeolites are widely used in industry owing to their large surface area and tunable pore size. However, because of their small pore size, their use is often limited due to low permeability and poor access to the active sites. To overcome transport issues encountered in microporous materials (< 2 nm) such as zeolites, efforts are devoted to design hierarchical materials combining different porosity scales. In this project pseudomorphic syntheses are used to prepare particles or monoliths of well-defined hierarchical materials with controlled porosities, morphologies, surface chemistries, etc…

Pulsed Field Gradient (PFG) NMR is widely used to study the diffusion properties of molecules adsorbed in porous materials. In this technique a static field gradient is applied to encode the spin position according to their resonance frequency and/or to the phase of the NMR signal. The attenuation of the proton signal obtained after a spin-echo sequence is related to the diffusion coefficient of the molecules. Several adsorbates with various chemical functions and sizes will be considered in order to evidence the diffusion contributions of the different porosity scales introduced during the synthesis.

We are especially interested in individuals with

- strong experience with NMR but knowledge of PFG techniques is not mandatory

- enthusiastic interest in physical data manipulation and modeling

- experience with powder sample manipulation and preparation will be a plus

Our lab is equipped with a state-of-the-art 300MHz Bruker Avance III HD spectrometer dedicated to diffusion and imaging experiments, either with static or rotating samples. It is part of the Science and Engineering faculty of Sorbonne Université located in the center of Paris, next to the Quartier Latin.

To apply, candidates should send the following to Flavien Guenneau

- A cover letter that describes your relevant experience, research interests, and career goals.

- CV including the names and contact information of 2-3 references
