The primary research interests of the Key Laboratory include:  searching for the growing mechanism of nanoscale systems in order to obtain the controlable growing nanosize structures; expanding the research scopes of 'internal friction' and developing the research methods combined with other advanced experimental instruments; investigating the relationship between the macroscopic physical properties and the microscopic structure in materials;  numerical simulations and predictions on the properties of materials; designing new materials with particular structures and novel characters; and developing high performance functional materials and devices.
