My scientific research involves all aspects of nucleation theory, formation of liquid droplets in supersaturated vapor. I am interested in homogeneous and heterogeneous nucleation on different types of nucleation centers. The main method I use in my work is the Density Function Theory (DFT). Using this approach, I have published several papers on interfacial properties of liquid-vapor interfaces and their significance for nucleation theory.
I have previously studied surface tension of spherical droplets and its dependence on droplet's curvature. This work was done for different types of fluid intermolecular potentials and simple monatomic and dipole fluids. I have also studied the behavior of liquids near solid walls and, in particular, heterogeneous nucleation on macroscopic and microscopic wettable nucleus.
My current work is focused on the curvature dependence of the disjoining pressure for thin liquid films.
In recent years, Physics Education has also become another major subject of my scholarship activity. As a result, the Modular Curriculum Approach (MCA) was designed and implemented at McMurry University for teaching introductory physics courses. The MCA is innovative by creating a blended learning environment, which consists of a system of instructional modules, where lecture, lab, and discussion are merged into one technologically and collaboratively rich experience. Flexible instructional spaces and Tablet PC technology are used to improve continuity among various module components. The modular format and innovative application of tablets allow instructors to (1) maximize proportion of inquiry-based learning; (2) achieve better integration of laboratory exercises with the lecture content; (3) maximize opportunities for active learning; (4) support peer instruction in learning communities; (5) offer flexibilities to benefit students with different levels of preparation and learning styles. A technology suite incorporated with tablets includes java-based Physlets, tablet-adapted personal response systems, PASCO data acquisition systems, and tablet-based note-taking tools.
My current Physics Education research has shifted towards rethinking teaching approaches towards upper division physics courses and incorporating computational projects into these courses.
