Molecular Simulations for Phase Transformations of Water
Project Goals and Description:
This research focus on understanding the molecular processes involved in the assembly of water and gas molecules to form clathrate structures. We use molecular simulations to follow the motion of the molecules, which under proper temperature and pressure conditions, can order to form cage structures. The initial process of ordering of the molecules leading to a critical size is known as the nucleation. The nucleation is the nascent cluster of molecules for a phase transformation. Our interest in clathrate hydrates is to study the fundamental thermodynamics and kinetic molecular projects that causes molecules to transition from one phase to another. Clathrate hydrates are a unique solid phase of water combined with gas playing an important role in energy storage, energy transportation, and energy transfer. This work solely computational and will expose the student to molecular simulations, molecular visualization, and big data analysis.
Grand Challenge: Provide access to clean water.

Students should have a desire to learn and especially interest in working with computer, programming, and simulations. It is also useful to have a good knowledge of thermodynamics.
TIME COMMITMENT (HRS/WK)
Students will gain skills on solving problems, computational skills, and big data analysis. Students will also be exposed to high-performance computing.
Regular weekly meetings will be scheduled with the students to develop the project and establish a regular timeline for progression.
