Core-shell and Mesoporous Particles

  • We work closely with our collaborators in modeling core-shell/mesoporous particles with the ultimate goal of enhancing their structural, magnetic, optical or catalytic properties. Further, we evaluate the role of strain engineering, phase transition and/or defect chemistry on their materials properties.

  • We are particularly interested in examining the effect of aggressive environments on the mechanical & chemical integrity of these structures. For example, the water interaction with porous silica-based structures at elevated temperatures is of a great interest for many catalytic applications. Using reactive molecular dynamics,  we examine the stability of a variety of zeolites againts the degradation (e.g. collapse of the porous structures) caused by liquid water at high temperatures & high pressures:
