Chayene Anchieta
About
Chemical engineer motivated by the development of new technologies of energy storage and conversion systems. 5 years of experience with the development of electrochemical cells for operando characterization, electrodes and batteries. More than 9 years of experience with materials synthesis, design and optimization. Chayene G. Anchieta received her Master’s degree on catalysts for oxidative process from University Federal of Santa Maria, Brazil. Has PhD from Federal University of Sao Carlos, Brazil, on Power-to-syngas using NiO-based catalysts for tri-reforming of methane, the future reforming of biogas. Since 2015, Chayene was working with in situ synchrotron characterization, she performed many experiments in the Brazilian Light Source. She had her first postdoctoral fellow at University of Campinas (UNICAMP) in Brazil, where she was engaged on different projects to develop new electrodes to be applied as a cathode in Li-O2 cells. The projects also work on the development of redox mediators for O2 reactions to improve the robustness of the electrode design. In-situ characterization techniques under real operating conditions, was performed in a separate project, aiming the development of new electrodes. Moreover, she developed new prototypes cells for in-situ characterization under real operating conditions, to understand the surface chemistry and the interaction of the species formed with the electrodes used. Chayene was postdoctoral fellow at Paul Scherrer Institut in Switzerland for more than 2 years at microXAS beamline in the Chemical Imaging Group, using X-ray imaging characterization with synchrotron radiation to study the chemical changes and interactions over the Ni catalysts applied to different batteries systems. During her period at PSI she also performed experiments with neutron image. She is a collaborator researcher at UNICAMP in a project of green hydrogen from biomass and amonia. As a researcher at NTNU is working in the context of ICONIC project, 3D CT of Li-ion batteries and carbon capture and storage (CCS).
