WPI-MANA: Reaping Benefits of Collaboration and Integration

TSUKUBA,Japan,July 26,2021 -- WPI-MANA established several special research programs in 2016 in the beliefthat "science can make strong advances through the integration of research."

Four of the key researchers in these programs -- Dr. Waka Nakanishi and Dr. Ayako Nakata in the Theory-Experiment Pairing Program,and Dr. Toshikaze Kariyado and Dr. Takuya Iwasaki in the Challenging Research Program -- sat down with MANA e-Bulletin to discuss their work and their experience with these programs.

Q: Let's start with a description of your research.

Nakanishi: In organic chemistry,we create organic molecules in the desired form by connecting carbon atoms. Since their structure is directly related to their functions,I focus on realizing functions by designing molecules.

Nakata: I do theoretical research using first-principles calculations. Ideally,we can know the electronic state of a material from calculations. However,it's difficult to simulate systems with many atoms,because it requires vast computational resources. Therefore,we developed a program called CONQUEST to determine the state of systems and molecules containing many atoms. We are now applying it to various real-life material systems.

Kariyado: My research is on clarifying the properties of materials using theory. There are many meanings to the term "properties of materials," but I focus on how to control the electronic state in matter.

Iwasaki: I am interested in electron transport,which is the source of electric current,and my research aims to clarify the properties of materials. I am particularly interested in two-dimensional materials,mainly graphene. Ideally,graphene is flat,but if the substrate is uneven,it loses its exceptional properties. To solve this problem,we are developing a technique to superimpose graphene on a very flat 2D material.

Q: How did you start your collaboration?

Nakanishi: In organic chemistry,we often look at the function of a molecule as an "overall average" under easy-to-measure conditions. Experiments that look at the shape and function of single molecules are still in their infancy...
