January 2018 - The Laboratory of Molecular Simulation (LSMO) at EPFL Valais Wallis
“The Laboratory of Molecular Simulation (LSMO) at EPFL has selected Chemspeed Technologies in order to accelerate their research work in discovering novel nanoporous materials. The overarching goal of this project is to identify a ‘wonder’ material that can outperform existing materials reported and available in the market for energy, environmental and sensing applications!
High-throughput methods represent a very promising approach for accelerating the discovery of metal-organic frameworks (MOFs) as a large number of automated and integrated reactions can be prepared in one batch by screening a wide variety of parameters: metal source and solvent mixtures, concentrations, ratio between the metal and ligand, pH of the reaction, heating temperature, time and others. The utilization of RoSy (Robotic Synthesiser ISYNTH SWAVE) at EPFL Valais Wallis is an ideal tool for the discovery of new materials as it allows the LSMO researchers to run a series of 50 (or more) simultaneous experiments for the synthesis of MOFs (automated dispensing of solids – ligands, metal salts and liquids with high quality; automated capping and crimping of the reaction vials without manual interference; microwave heating; confirmation of the product formation with the integrated camera). The experimental results (successful and failed) are then utilized to rank each synthetic reaction with the Genetic Algorithms (GAs) – an approach that the computational scientists in LSMO have developed. After this ranking, a set of new synthetic conditions is generated and run experimentally using RoSy. This can lead in multiple generations of MOFs (set of 50 reactions) and it continues until the best conditions are identified. Recent advances from this research activity include the discovery of new MOFs and the optimisation of the synthetic conditions for the synthesis of stable, originally reported as unstable MOFs. Additionally by establishing this robust iterative method, the design and synthesis of specific MOF for the capture / storage of strategically critical gases (CH4, CO2, H2) can be achieved!”
