Physical Chemistry

Physical chemistry is the study of macroscopic, and particulate phenomena in chemical systems based on the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibrium. Newly developed spectroscopic methods help researchers investigate reaction pathways in homogeneous phase or on the surface of heterostructure materials. Scientists in the Tunghai University have developed new strategies to understand the molecular behavior, surface science and electrical conductivity of materials through visible, infrared and X-ray analytical spectroscopy. Thus, the field of physical chemistry plays an important role in the development of new energy technologies such as new photocatalysts, electrocatalysts, reaction mechanisms for rechargeable electrochemical cells and new perovskite materials. These studies offer great potential and possibilities for the next era of sustainable energy.

Energy Conversion

Tunghai University's research on emerging energy conversion and storage technologies focuses on electron/hole transport in perovskite-based solar cell materials, and active electrode materials for rechargeable Al ion batteries. The development of chemical materials at the molecular level is a key determinant of the ultimate success of these technologies.

Structure and Reactivity

It is important to study the relationship between the structure of a material and its chemical reactivity. Analysis of advanced spectroscopy and modeling techniques allows for detailed fine structure and bonding types in chemical materials. Realizing the details of the structure of the materials and their reactivity is an important issue in designing specific materials for different applications.

Advanced computing

Theoretical computational chemistry focuses on the use of effective mathematical approximations and computer programs to calculate the properties of molecules such as total energy, dipole moment, quadrupole moment, vibrational frequency, reactivity, etc. Further it can also explain some specific chemical reaction mechanisms. Tunghai University faculty members discuss the reaction mechanism of chemical materials in chemical reactions through advanced computational methods. In conjunction with in-situ spectroscopic analysis, the real reaction mechanism of the  chemical reaction can be revealed.

Physical optical property

The unique optical absorption or photoluminescence of chemical materials will change during chemical reactions in the presence of incident electromagnetic radiation. The study of changes in optical properties has been used to understand the motion of atoms in molecules and the behavior of electron transfer in materials. The high quality 2D perovskite nanomaterials developed by Tunghai University exhibit significant photoluminescence during the reaction, ranging from green to red emission colors as a result of the transformation from zero-, two- and three-dimensional structures.
