The Interfaces (IF) group conducted both in-depth scientific research and industrial problem solving. We have a wide range of research capabilities in computational and material chemistry, from surface adsorption to interfacial properties, reaction mechanism, as well as catalyst design. With a focus on catalysis, corrosion & coating and consumer care research, IF group is positioned to support chemistry-related industries as the new product is developed.
Our key mission is to help solve critical problems in chemistry-related industries (chemical, maritime and consumer care) through our technical expertise.
The consumer care research in MSE currently focuses on topics such as molecular assembly, polymers, anti-microbial molecules and surfactants. We are using molecular modelling techniques to improve fundamental understanding of the chemical, structural, and binding properties of materials, to investigate the structure-property relationships of molecules, and to gain mechanistic understanding of molecular processes. These understanding will aid in the design and development of better products for the consumer care industry.
Furthermore, we have also developed a simple hair surface model to investigate the detailed structure of the hair surface. The hair surface model can be used as a platform to study the interactions of molecules with the hair surface. This would be important in the design of new active molecules for shampoo and conditioner applications.

Corrosion and Coating
Under high temperature or a marine environment, corrosion of structural materials is inevitable. Control of the corrosion can avoid structural failures or reduce the costs of major renewals during the economic life of the vessels. Through the use of first principles and thermodynamic modeling, we can understand the corrosion mechanism and provide guidelines for materials selection for a coating to protect against corrosion. Some of our experience includes corrosion study of copper wire bonding under humid environment, erosion and spallation resistance materials study for thermal barrier coating and abradable coating materials design for high temperature applications.
