Nanomaterials Science and Engineering Lab (NSE)

The NSE focus on the development of novel architectured materials in multi-dimensions through programmed assembly or printing of tailored nanoscale building blocks. To this end, we study the chemical strategies to control over physicochemical properties of individual building blocks as well as their many-body interactions. Moreover, we develop new processing to build up designed architectures from nano- or micro-building blocks. Ultimately, we explore the application areas of architectured materials in multiple length scales as electronic and energy materials.
