Nanoenergetics

Nanoenergetics

We are interested in fundamental processes of energy harvesting, conversion, transfer and storage in nanoscale materials and devices, with a vision for applications ranging from nanoelectromechanical system, nanoelectronics to sustainable energy sources by utilizing novel nanostructures. Typical scientific and engineering problems we are solving include energy harvesting and dissipation in nanomechanical devices, electromechanical coupling and (electron, phonon) transport at nanoscale interfaces.

Bioenergetics

Bioenergetics

Benefiting from the evolution of billions of year, nature finds a smart way to manage the energy flow, which supports the living organisms system in our planet. One example is the photosynthetic system in plants and algae. Rather than focusing on single figure of merit, natural systems are usually multifunctional, assisted by their hierarchical structures and multiphysical functioning. Based on the growing understanding and inspiration of nature, we seek for an alternative way to develop energy-efficient materials and devices.

Materials and devices

Materials and devices for energy and environment applications

We look for novel materials and devices in sustainable energy and environment-friendly applications, with special focuses on the development and applications of our computational methods. Examples include efficient thermal management network, high-performance thermal and electrical transport grids, energy storage materials and devices.

Industry

Key energy and environmental problems in industry

Working together with our industrial sponsors and collaborators (list), we solve key energy problems in the industry (manufacturation, transportation, etc). Our current focuses are placed on designing novel membrane materials for water and air filtration, high-performance and multifunctional nanostructured materials, interface with ultralow friction and wear, electronically insulating but thermally transparent nanoelectronic interfaces. In addition to simulations, experimental developments are pursued for some projects.
