  • Patent number: 9175412
    Abstract: Disclosed are an Fe—Au barcode type nanowire and a method of manufacturing the same. The nanowire has a magnetic-optical multifunction and is suitable for adjusting magnetic intensity thereof. The Fe—Au nanowire has a multilayered structure, in which an iron layer and a gold layer are alternately and repeatedly formed, and is formed in a single plating bath through a pulse electro-deposition.
    Type: Grant

  • Patent number: 8557337
    Abstract: Provided are magnetic core-ceramic shell (e.g., magnetite (Fe3O4) core-calcium phosphate (Ca3(PO4)2) shell) nanocrystals with high crystallization degree, uniform size, and high chemical stability and a method for synthesizing the same. A core-shell structure is synthesized in a process of forming magnetite seeds corresponding to cores by the reduction of magnetite precursors and then, sequentially, coating the magnetite with Ca3(PO4)2 by the reduction of Ca3(PO4)2 precursors.

  • Publication number: 20070295603
    Abstract: Provided is a method of manufacturing a nanoplate diamond. In the method, nanotemplates having a plurality of holes are provided, and nanoplate diamonds are formed in the holes of the nanotemplate using an electrochemical method. After that, the nanotemplate is removed to separate the nanoplate diamonds from it.
