    摘要： A nanocomposite material having a plurality of core particles formed of a core material. The core material has a first glass transition temperature. A shell encapsulates each core particle. The shell is formed of a shell material that has a second glass transition temperature less than the first glass transition temperature. When subjected to a temperature greater than the second glass transition temperature and less than the first glass transition temperature, the shells form a continuous matrix surrounding the core particles. The shell material includes a functional component that can be activated in response to an external excitation. This functional component can include either photosensitive, semiconductor, magnetic, piezoelectric or electro-active components just to mention a few. The different components may be chemically or physically bound to the shell or cores. These nanocomposite materials are used as storage media.

    摘要： A method of producing three dimensional ordered arrays of particles. The method may be used for the preparation of nanocomposite materials with highly periodic structures. More particularly the invention provides a method of producing three dimensional arrays based on applying a controlled oscillatory motion to settling dispersions of colloid particles. The controlled oscillatory motion is characterized by G=A&ohgr;2/g, wherein g is the gravitational constant, A is the displacement and &ohgr; is angular frequency. G is maintained in the desired range by varying values of A within an effective range of displacements and &ugr; within an effective range of frequencies.
