    Here, we synthesized matchstick-shaped Janus nano-surfactants that mimic organic surfactant molecules and studied their programmable self-assembly. High amphiphilicity was achieved through the hard–soft acid–base-based ligand-exchange reaction with strong selectivity on the surface of nano-matchsticks consisting of Ag2S heads and CdS stems...

    Herein, we report a generalised direct optical printing technique to obtain functional metal chalcogenides via digital light processing. We developed universally applicable photocurable chalcogenidometallate inks that could be directly used to create 2D patterns or micrometre-thick 2.5D architectures of various sizes and shapes...

    Herein, we present a solution-processed fabrication of high-performance Ag-doped SnSe thin films operable in a low-temperature range. The Ag doping induces the preferred crystallographic orientation and grain growth in the b–c plane (in-plane) of SnSe, consequently enhancing thermoelectric performance at low temperatures...

    Here we show that microscale 3D thermoelectric architectures can be fabricated through the direct writing of particle-based thermoelectric inks... the characteristics of (Bi,Sb)2(Te,Se)3-based particle inks are engineered to create colloidal inks with high viscoelasticity and without organic binders, and the inks are directly written into complex architectures...

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.
