Ferroelectric bilayer composites with giant electromechanical properties. This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale.

This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale. Traditional electromechanical devices based on ferroelectric materials including position sensors, mechanical actuators, and ultrasonic transducers rely on bulk form. As technology moves toward integrated functionalities, future electro-mechanical materials need to be scaled down to thin film form. Currently, doing this induces mechanical constraints that dramatically suppress the electromechanical response. Using this approach one layer relieves this mechanical constraint while the other gives a giant electromechanical response, providing a pathway for future functional devices. Read moreRead less

Smart Materials Between Two and Three Dimensions. Shape-memory alloys involving martensitic transformations, are important as smart materials. Both the transformation nucleation and the sample morphology are unsolved issues relevant for these applications. Of particular note are the softening of certain lattice-vibrational frequencies, the development of a tweed-like microstructure on cooling the material and the role of defects, particularly the sample surface, in the transformation process. ....Smart Materials Between Two and Three Dimensions.

Both the transformation nucleation and the sample morphology are unsolved issues relevant for these applications. Of particular note are the softening of certain lattice-vibrational frequencies, the development of a tweed-like microstructure on cooling the material and the role of defects, particularly the sample surface, in the transformation process. This project addresses these issues using model materials in thin-film and bulk-crystal forms. Capacitance dilatometry, optical, electron and scanning-probe microscopies, and x-ray techniques, will unlock an understanding of the physical and metallurgical conditions controlling these transformations.Read moreRead less

This project aims to engineer electrolyte materials, based on organic ionic plastic crystals, and use isomeric doping to improve the ionic conductivity. The development of safer batteries relies on eliminating the volatile and flammable solvents commonly used as the electrolyte. Improving the safety and performance of batteries is important as electricity costs increase. Solid state ionic electrolytes can address leakage and volatility problems, but the conductivity must be improved if these materials are to support high battery power. The project’s electrolyte materials can be used in lithium metal batteries, which have higher theoretical energy densities than traditional lithium ion batteries. This project will develop new solid state electrolytes, with improved conductivity, and use these materials in emerging lithium battery technologies.Read moreRead less
