Carlos E.Aristizábal. Hello! I am Carlos E. Aristizabal. I studied chemical engineering and now I am doing my PhD at the Instituto Tecnológico Metropolitano de Medellín (Colombia) on hydrogenation of α, β-unsaturated aldehydes. During my PhD I am studying Cu, Ni and Re nanoparticles supported on different oxidic and carbonaceous materials using formic acid as in-situ hydrogen donor in gas phase. Within BIOALL I am doing a 5 months’ stay at ICP-CSIC in 2022 with Dra. Ana Belén Dongil
