Current Research Interests
Metal-organic frameworks (MOFs) are a class of highly porous crystalline materials that have shown many interesting structural and chemical properties. Their modular synthesis from metal corner units bridged by organic linkers, together with the possibility of postsynthetic functionalization makes them promising materials for numerous applications including adsorptive storage and separation of gases and liquids.
My current research is devoted to study the role played by open metal sites in gas adsorption and selectivity of various gases including CH4 and CO2, especially at low loadings when host-guest interactions are more important. The characterization of the changes in the local structure and the electronic properties of the metal centre upon adsorption of gas molecules by mean of less conventional spectroscopy techniques such as X-ray Emission Spectroscopy (XES) or Energy Dispersive EXAFS (EDE) could potentially help in the further understanding of the gas adsorption and selectivity at the uncoordinated metal centres.
My previous areas of expertise include the study induced magnetic moments in various materials by mean of X-ray Magnetic Circular Dichroism, synthesis of alloys by arc melting and the use of X-ray phase retarders for changing the polarization of X-rays.

Roberto Boada Romero graduated in Physics at the University of Salamanca (Spain) and completed his PhD at University of Zaragoza (Spain) under the direction of Dr. Jesus Chaboy. Later he joined Diamond as visiting scientist on I20 beamline participating in the development of the energy dispersive EXAFS beamline. Currently he works as PDRA on the I20 beamline and his project is focused on the study of gas adsorption on metalorganic frameworks (MOF) using X-ray spectroscopy techniques.
