Sometimes it is the tiny things in the world that can make an incredible incompatibility. One of these things is the nanoparticle. Nanoparticles may be small,but they have a variety of well-known applications in areas such as, medicine, or manufacturing,and energy. A team of researchers from Okinawa Institute of Science and Technology Graduate University (OIST) recently discovered a unique copper-silver nanoparticle structure that has a core of one element surrounded by a "cage" of the other element. However, the cage does not cover certain areas of the core, or which very much resembles the Japanese glass fishing floats traditionally covered with rope called ukidama.
