Guagliardi Antonietta


I am a senior scientist at Institute of Crystallography (IC) of CNR, Italy, Como branch. My major research interest focuses on the development and application of experimental and modeling tools to investigate nanocrystalline materials at the atomic and nanometer scales based on X-ray total scattering, so that both Bragg and diffuse scattering are equally taken into account. On this topic, I have been coordinating an extended network of collaborations, set at the Total Scattering Laboratory (To.Sca.Lab) in Como, which includes scientists from University of Insubria and CNR, and from the Material Science Beamline of the Swiss Light Source, where total scattering experiments are carried out in the wide-angle region and where suitable data acquisition and data reduction protocols have also been developed. A major research line in the field is the modeling in reciprocal-space, based on atomistic models of nanocrystals and composites, and the use of the Debye Scattering Equation, with original contribution to the development of dedicated computational tools (Debussy Suite). Advances of this approach, together with combination of wide and small angle scattering, have been pursued through investigations of ultrasmall semiconductor nanocrystals (metal chalcogenides and metal halide perovskites), particularly from colloidal synthesis, but also metals, oxides and nanocomposites. The goal is extracting quantitative information on size- and surface-induced structural distortions, symmetry breaking, lattice strains and different kinds of defectiveness for structure-property correlation studies.

During my education and 35 years long career, I have acquired a broad background in crystallography, diffraction techniques and ab initio structure determination by Direct Methods, working in the group led by Prof. C. Giacovazzo, and contributed to the development of popular crystallographic packages (SIR92/SIR98 and EXPO) to solve crystal structures by single crystal and powder diffraction data. Since 2003, I have started setting my own research line(s) focussing on nanocrystallography and X-ray Total scattering methods, including experimental, modeling, analytical and structure-property correlation aspects. I have got a PhD in Chemistry at the University of Insubria, Italy, with a Thesis on the application of the Debye Scattering Equation on nanomaterials for investigating structure-property correlations.

I have co-authored 120 papers in peer-reviewed international journals in Crystallography, Chemistry, Material Science. H-index= 34, Sum of citations (without self-citations) > 28000 (Web of Science). Over 100 communications at National and International conferences. I have co-authored 11 book chapters and co-edited 3 books.

I have a long-standing experience in the organization of schools on fundamental crystallography and total scattering and in managing hands-on with the packages I have co-authored. I have supervised/sing the research activity of many PhD students and post-docs.
