Short presentation
I work on theoretical and computational predictions of geometrical effects on thermodynamic and transport behaviors of confined systems. It includes quantum size, shape, and curvature effects. Another topic of my interest is the systems having fractional dimensional momentum spaces. Using their unusual behaviors, I also propose some conceptual new energy conversion and storage technologies. I am collaborating with Prof. Dr. Jonas Fransson on these topics.
