Professional Biography

Born and raised in Argentina, Prof. Calbi earned her PhD degree in physics at the University of Buenos Aires in 2000. She then completed her training in condensed matter physics at the Pennsylvania State University where she made her first contributions in the theory of gas adsorption on solid surfaces. In 2003, she joined the Physics Department at SIUC, and in 2010 she moved to University of Denver where she has been Associate Professor in the Physics & Astronomy department. One of her main interests lies on determining the ability of a variety of nanostructures to act as adsorbents by developing models and methods that can provide a basic understanding of the adsorption processes and phenomena (equilibrium and kinetics) in nanoporous materials. From a practical perspective, the goal is to provide a rational basis for assessing the performance of a nanostructure for specific adsorption applications that can be used, at the same time, to guide the design of new materials for such uses.

Our main research interests are in the area of surface physics, especially focused on adsorption processes, i.e., the processes by which particles from gases or liquids are attracted to solid surfaces and stick to them forming different kinds of films. The recent (and continuous) emergence of a variety of novel nanostructures that can act as adsorbents has boosted a remarkable amount of research in this field due to both its practical and fundamental implications: On one hand, the size and morphology of these structures make them especially efficient for gas storage and separation applications, including gas purification, environmental remediation and membrane technologies; on the other hand, particles adsorbed on nanostructures are constrained to be in environments of reduced dimensionality where their behavior can be significantly different from that of bulk matter. Both aspects pose important challenges and questions that our research program aims to address. The theoretical methods and models we use are based on combined approaches from statistical mechanics and chemical physics, including computer simulations. Particular efforts are made to formulate models that provide a fundamental understanding of the investigated phenomena, allowing at the same time direct comparison with experimental results. Some of our ongoing research projects include: Adsorption kinetics and transport in nanoporous structures, adsorption of polyatomic molecules on carbon nanotube bundles, and adsorption behavior in nanohorn aggregates.
