Highlights

Prix de Thèse 2020 de l'Ecole Doctorale ED352
Nous avons le plaisir de féliciter Melle Pingping Jiang qui fait partie des lauréats 2020 du prix de thèse de l’ED 352 Physique et Sciences de la Matière.
Pingping Jiang a effectué sa thèse de doctorat dirigée par le Pr. Pascal Boulet et le Pr. Marie-Christine Record (IM2NP).
Les travaux de thèse ont porté sur les calculs de premier principe réalisés sur des structures à base de chalcogènes pour applications photovoltaïques.
Tailoring the separation properties of flexible metal-organic frameworks using mechanical pressure
Nature Communications 2020
In this work, Nicolas Chanut and Philip Llewellyn, along with Sandrine Bourrelly, Marie-Vanessa Coulet and Bogdan Kuchta, established a proof-of-concept for the molecular sieving separation of species with similar sizes (CO2/N2 and CO2/CH4), via precise mechanical control of the pore size aperture in a flexible metal-organic framework.
Claire Dazon has been awarded the Thesis Prize SFNano 2019 in the category Applied Research
Claire Dazon carried out her doctoral research in a collaboration between MADIREL and the French National Research and Safety Institute for the Prevention of Occupational Accidents and Diseases (INRS) in Nancy. Her work concerned the characterization of nanopowders along with methodologies to identify and classify this class of potentially dangerous material. Un grand BRAVO à Claire :-))
Towards general network architecture design criteria for negative gas adsorption transitions in ultraporous frameworks
Nature Communications volume 10, Article number: 3632 (2019)
Paul Iacomi and Philip Llewellyn carried out the adsorption and specific calorimetry measurements on this fascinating family of switchable metal-organic frameworks.
Metal-organic framework crystal-glass composites
Jingwei Hou, Christopher W Ashling, Sean M Collins, Andraž Krajnc, Chao Zhou, Louis Longley, Duncan N Johnstone, Philip A Chater, Shichun Li, Marie-Vanessa Coulet, Philip L Llewellyn, François-Xavier Coudert, David A Keen, Paul A Midgley, Gregor Mali, Vicki Chen, Thomas D Bennett, Nature Communications, 2019, 10(1), 2580-
Adsorption measurements carried out by our group were able to highlight the enhanced uptake of hydrogen and carbon dioxide in the composite materials with respect th the bare materials.
Screening the Effect of Water Vapour on Gas Adsorption Performance: Application to CO2 Capture from Flue Gas in Metal–Organic Frameworks
Nicolas Chanut, Sandrine Bourrelly, Bogdan Kuchta, Christian Serre, Jong-San Chang, Paul A. Wright, Philip L. Llewellyn (DOI: 10.1002/cssc.201601816) has been selected by ChemSusChem as a very important paper (link)
Our group was one of the first to study the use of external mechanical pressure to induce flexibility (compression/decompression) in Metal-Organic Frameworks [ACIE2010]. We have taken this forward with the development of direct energy measurements using calorimetry [ACIE2015]. The present work shows our results with a pure oil system that can potentially be developed to real devices.
Methane storage in flexible metal–organic frameworks with intrinsic thermal management

Le stockage d’un carburant comme le méthane intéresse particulièrement l’industrie automobile. On sait depuis longtemps qu’il est possible de stocker sous pression davantage de gaz lorsque le container est rempli de matériaux poreux que lorsqu’il est vide, à cause du phénomène d’adsorption. Des équipes du Laboratoire matériaux divisés, interfaces, réactivité, électrochimie (CNRS / AMU) et du Department of Chemistry (University of California – USA) viennent de synthétiser un nouveau matériau hybride inorganique-organique, flexible, avec lequel ils ont obtenu des capacités de stockage supérieures à celles servées avec d’autres composés de la même famille. Ces résultats sont parus dans la revue Nature.
