Welcome to NIMS GREEN IFCS group homepage
Interface Computational Science (IFCS) group in
Center for Green Research on Energy and Environmental Materials (GREEN) was originally established in October 2007.
The main targets of the IFCS group are science and technology related to energy and environmental issues, through novel theoretical, computational and data-science techniques associated with first-principles calculations.
We are enjoying many discussions about novel theories/computational methods as well as update experimental findings in physics, chemistry and materials science. In particular, we focus on quantitative simulations of phenomena at solid-liquid and solid-solid interfaces on the atomic and electronic scales, and mainly deal with transition metal oxide and semiconductor electrodes as well as water and organic solvents.
As interface simulation is a cutting-edge research in the world at present, we have many high-quality guests working on similar projects and discuss the update theories, methods as well as interfacial phenomena.
The group is seeking contributions to both theoretical/computational sciences and practical physics, chemistry and nano-science. In this respect, we are interested in understanding realistic systems/phenomena, and pleased to discuss with experimentalists, intensively. From application point of view, we're working on issues in catalysis & photocatalysis, dye-sensitized solar cell, secondary battery, and have collaborations with experimentalists. Of course, we're very happy to have discussions of theory and computational techniques as expert computational scientists.
