A new device designed to help scientists study in detail what happens during electrochemical reactions has been developed by researchers at the Center for Innovation in New Energies (CINE) in collaboration with researchers at the Brazilian Synchrotron Light Laboratory (LNLS), a unit of the Brazilian Center for Research in Energy and Materials (CNPEM). CINE is an Engineering Research Center (ERC) established by FAPESP (São Paulo Research Foundation) and Shell and is hosted by the University of Campinas (UNICAMP) in the state of São Paulo, Brazil.
