  • Methods of metal oxide nanocrystals preparation
    Patent number: 9981900
    Abstract: Embodiments relate to methods of metal oxide nanocrystals preparation. In embodiments, a metal-organic precursor may be economically synthesized by reacting a metal with an organic acid. The organic acid may include an aliphatic chain longer than three carbon atoms. The metal may be In, Sn, Al, Ga, Zn, Cd, Sb, Bi, Ge, Mn, Ti, Nb, V, Cr, Mo, Fe, Y, Mg, Co, as well as mixtures thereof. Further processing of the metal-organic precursor (e.g. by pyrolysis, hydrolysis, or alcoholysis) produces metal oxide nanocrystals of desired characteristics. An metal-organic precursor of indium tin oxide (ITO) may be synthesized by reacting indium metal and tin metal with an organic acid having an aliphatic chain longer than three carbon atoms (e.g. stearic acid) at a temperature above 200° C. Further processing of the resulting metal-organic precursor yields ITO nanocrystals of regular shape, uniform size, and average diameter ranging of between about 1-500 nm.

  • Aircraft and watercraft emergency information system
    Patent number: 8390468
    Abstract: A method for collecting and recording external environment data in emergency situation for aircraft and watercraft is provided. In one embodiment, the method includes several modules which collects and records external environment data. At the same time the data and the emergency signal is also sent to control tower in order to help the rescue team. The emergency information system may also be used to replace the ‘black box’ if the voyage data transmitted to the “black box” is also transmitted to the emergency information system.
