MiEl is a research and training project funded by the European Union’s Marie-Sklodowska-Curie programme. MiEl involves 9 partner organisations and 5 associated partners from 9 different countries, who will recruit 12 PhD students for the project. MiEl will develop a novel synthesis technology for the chemical industries, combining the advantages of electrochemistry, micro process engineering and flow chemistry. The ambitious research objective is to upscale these technologies using integrated cell concepts such as printed circuit board (PCB) technology with integrated process control functionalities, which can be assembled in arrays for the safe, flexible and sustainable synthesis of chemical products. It will allow new synthetic routes for the sustainable chemical industry of the future.
