2. Ceramic Materials
The Ceramic Materials group studies the science and applications of various functional and structural ceramic materials. A ceramic is an inorganic, nonmetallic solid comprising metal, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. Typical ceramic materials include transition metal oxide, nitride and sulfide, etc. The research at the Advanced Ceramics & Devices group is highly interdisciplinary, and a wide range of research and development topics are being carried out, including:
- Ionic Conductors/ Oxygen Sensors;
- Ceramic Components for very-large-scale integration(VLSI) Integrated-circuit Equipments;

- Near Net Shaping and 3D Printing for Ceramic Components;
- Full Solid State Lithium Ion Battery;
- Ceramic Fuel Cells;
- High-Temperature High-Strength Ceramics;
- Ceramic Materials for Energy Systems;
- Ceramics for Biomedical Applications.
3. Energy Materials
The Energy Materials research group focuses on novel materials and devices with energy applications meeting the special challenges of the 21st century. Its research can be classified into new energy materials, energy-saving materials and energy-storage materials. Current research activities of the Energy Materials group include:
- Development of Solid Oxide Fuel Cell (SOFC) power systems, including electrode, electrolyte, sealing materials, interconnect, single cell, and assembly design of the different scale stacks;
- Development of key materials for Dye-sensitized solar cell (DSSC) with improved photoelectric conversion efficiency;
- Development of Lithium, Li-Air, and Li-S batteries to improve their storage capacity, charge-discharge properties and cycle lifetime;

- Development of novel thermoelectric materials with improved thermoelectric conversion efficiency.
4. Amorphous Materials
The Amorphous Metals group conducts research on the processing/forming, structure and properties of amorphous metal alloys and other novel meta-stable materials. Amorphous metal (also known as “metallic glass” or “glassy metal”) is a novel solid state metallic material with a disordered atomic-scale structure. Most solid state metals have crystalline structure with ordered arrangement of atoms. Amorphous metals are non-crystalline, with a glass-like structure similar to soda-lime glasses used for windows and bottles. There are several ways to produce amorphous metals, including extremely rapid cooling (>105 K/s), physical vapor deposition (i.e., sputtering), thermal spraying, and mechanical alloying. Amorphous metals offer a variety of excellent properties such as high tensile yield strength (i.e., Co-based system is the strongest materials among metals), high elastic strain limits, high hardness and wear/corrosion resistance, thus allowing for broad range of applications in micro-electro-mechanical systems (MEMS), bio-materials, protective coating and thin films, and magnetic materials. Current research activities of the Amorphous Metals group include:
- Developing new metallic glasses, composites and nano-porous amorphous metals with excellent properties;
- Developing amorphous coatings (microscale) and thin films (nanoscale) by novel surface engineering techniques such as high velocity oxygen fuel (HVOF) and magnetic sputtering;
- Micro-forming and 3D printing of amorphous metals and their structure and properties;
- Glass transition and liquid-liquid transition in amorphous alloys.
