  • Publication number: 20070248678
    Abstract: The present invention provides for a metal oxide nanoparticle that contains a metal core, a shell formed on the surface of the core and consisted of the same metal as the core, and an organic compound containing an element capable of covalently bonding with the nanoparticle and a hydrophilic functional group. According to the examples, uniform-sized hydrophilic metallic oxide-based nanoparticles are obtained when superparamagnetic iron oxide particles, which have a globular shape and are less than 20 nanometers in size, are first synthesized in an organic solution, and then are converted to hydrophilic particles after undergoing surface modification.

  • Patent number: 7217390
    Abstract: The present invention relates to a method of fabricating ultra-fine grain cermet alloys with a homogenous solid solution grain structure. More particularly, the invention relates to a method of fabricating an ultra-fine TiC-base cermet alloy with a homogenous solid solution structure which does not comprise a core-rim structure in the carbide grain. The object of the present invention is to provide a method of fabricating a TiC-base cermet alloy without the core-rim structure. The above objects of the present invention could be achieved by employing a conventional sintering process (vacuum sintering) of (Ti,TM)C carbide obtained from a mechano-chemical synthesis (high energy ball-milling) from milling the powders of Ti, TM, Ni and Co metals.

  • Publication number: 20050213019
    Abstract: An in-plane switching mode liquid crystal display device includes upper and lower substrates, first and second ferroelectric liquid crystal layers, a nematic system crystal layer, and first and second electrodes. The electrodes and liquid crystal layers are located between the substrates, with the nematic liquid crystal layer between the ferroelectric liquid crystal layers. The ferroelectric liquid crystal layers have different spontaneous polarization directions. An electric field is applied to the liquid crystal layers using the electrodes. The ferroelectric liquid crystal layers react to different electric field to conduct an in-plane driving of liquid crystal molecules in the nematic liquid crystal layer.
