Adjunct Research Professor, Dept. of Physics and Astronomy
Dr. Nie’s research focuses are in the areas of analytical chemistry and surface chemistry. He is interested in developing analytical approaches to studies in soft materials, mainly using time-of-flight secondary ion mass spectrometry (ToF-SIMS) and atomic force microscopy (AFM). He carries out research work on the manipulation of the surface energy of materials with surfactants for enhancing the chemical stability and compatibility of organic/inorganic hybrid systems such as organic electronic devices and polymer composites.
Current research activities include:
- Exploring formation mechanisms of self-assembled monolayers (SAMs) on oxides and their applications in surface engineering.
- Developing ToF-SIMS approaches for quantification of the degree and depth of cross-linked thin polymer films.
- Developing AFM techniques for imaging additives in a polymer matrix.
