The research activities in Shaw's group focus on synthesis and processing of advanced materials for energy and structural applications. Several projects are taking place concurrently, which include:
- synthesis and fabrication of novel electrode chemistry and architecture for Li-ion batteries, Na-ion batteries, electrochemical capacitors, and redox flow batteries;
- investigation of novel hydrogen storage materials for fuel cell vehicles; and
- novel synthesis and processing of nanostructured metals and ceramics for mechanical applications.
The superior properties of the aforementioned materials are achieved through new chemical compositions, novel processing techniques, and innovative microstructure control. High energy ball milling, wet chemical synthesis (e.g., co-precipitation, hydrothermal, and sol-gel processing), sintering, integrated mechanical and thermal activation, and additive manufacturing are just several examples of the processing techniques that we have studied in order to attain novel properties for energy and structural applications.
