Abstract:

In this talk, I tend to show that very special properties or new discoveries are generated via capability to manage two completely opposite elements or phenomenon to co-exist at small scale in one system. These can be exampled from a wide range of scientific problems. Superconductivity and magnetism are antagonistic phenomena but when these are manipulated to co-exist at lattice scale a very strong pinning force is resulted to pin the magnetic fluxes, leading to high field performance of the superconductor for applications. Co-existence of carbon modified surface and untouched interior at nanoscale leads to a breakthrough in high field critical current density of MgB2 superconductors. Co-existence of phonon glass and electron crystal in thermoelectric materials achieved by multi-scale scattering resulted in an ideal state for increasing figure of merit to effectively covert waste heat to electricity. Combination of active and inactive materials in energy storage system is the best strategy to ensure the electrochemical reactivity and structural integrity. A coexistence of body insulator and surface gapless conductor has led to the discovery of a completely new class of material: topological insulator with extraordinary properties. Coexistence of spin quantum liquid and crystalline solid in one system leads to the discovery of third kind of magnetism which is very significant to understand high temperature superconductivity and application of data storage.
