20080210899Magnetic Core - Ceramic Shell Nanocrystals and Manufacturing Method Thereof - Provided are magnetic core-ceramic shell (e.g., magnetite (Fe09-04-2008
20090155617IRON-GOLD BARCODE NANOWIRE AND MANUFACTURING METHOD THEREOF - 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.06-18-2009
20090275345APPARATUS AND METHOD FOR PROVIDING LOCATION INFORMATION AND APPARATUS FOR SUPPORTING LOCATION BASED SERVICE AND METHOD FOR USING LOCATION BASED SERVICE - A location information providing apparatus to provide a location thereof, the location information providing apparatus including: a storage unit to store location information regarding the location of the location information providing apparatus; and a transmitter to transmit the location information. Therefore, precise location information can be provided. In addition, a location-based service can be performed in a simple way because there is no need to consider a handoff depending on a movement of a location-based service supporting apparatus, and a service area can be expanded abroad because a wired network is not required. Also, various opportunities using the location-based service can be realized.11-05-2009
20100163419METHOD FOR FABRICATING MULTI-COMPONENT NANOWIRES - A method for fabricating multi-component nanowires is disclosed, which can make multi-component nanowires used to realize a nanowire-based memory device by an electroplating process using a multi-component solution. The method for fabricating multi-component nanowires in accordance with the present invention includes the steps of: (a) preparing an anodized aluminum oxide nanotemplate having a plurality of pores; (b) forming an electrode layer on one surface of the anodized aluminum oxide nanotemplate; (c) injecting the anodized aluminum oxide nanotemplate in a predetermined multi-component solution and then growing multi-component nanowires through the pores of the anodized aluminum oxide nanotemplate by an electroplating process in which the anodized aluminum oxide nanotemplate is used as a cathode; and (d) removing the anodized aluminum oxide nanotemplate.07-01-2010

20080304501TUNNELING SERVICE METHOD AND SYSTEM - A tunneling service method and system enabling data communication between different networks, in which an address of a tunneling service server used in a client node can be easily designated, the tunneling service method includes: transmitting an information request message, which requests information required for connection to the network, to a dynamic host configuration protocol (DHCP) server selected by the client node; receiving an acknowledgement message, which contains an address of the tunnel router, from the DHCP server selected by the client node; and the client node detecting the address of the tunnel router contained in the acknowledgement message and generating a packet for a tunneling service using the detected address of the tunnel router.12-11-2008
20090201886METHOD OF AND APPARATUS FOR ADJUSTING QOS IN DATA TRANSMISSION OVER SCTP SESSION - A method of adjusting quality of service (QoS) with respect to changes in a transmission environment of a mobile terminal receiving data based on a stream control transmission protocol (SCTP) session. When the transmission environment of the mobile terminal receiving data based on the SCTP session changes, the mobile terminal transmits link information indicating a new transmission environment to a destination node, and the destination node adjusts the quality of data or the size of a transmission window based on the link information. Thus, without adding separate network devices, the QoS of the data being transmitted can be adjusted with respect to the changed transmission environment, only by adding functions with software to the transmission terminal and the reception terminal. Also, since the destination node manually adjusts the transmission window according to the link information, packet loss can be minimized compared to the conventional congestion control method.08-13-2009

20110220205Electrolyte-comprising polymer nanofibers Febricated by electrospinning Method and high Performance dye-sensitized solar cells Device using same - A polymer electrolyte including a polymer fiber having a nanoscale diameter, wherein the polymer fiber is fabricated by an electrospinning method and a solar cell device exhibiting high energy conversion efficiency using the same. The solid-state electrolyte comprising such nanosized polymer fiber does not need a sealing agent and further simplifies the entire process compared to a conventional dye-sensitized solar cell using liquid electrolytes. Specifically, the energy conversion efficiency of the present dye-sensitized solar cell is significantly superior to that of a dye-sensitized solar cell using a polymer film electrolyte fabricated by a spin coating method. Further, the present dye-sensitized solar cell device can be obtained by using a scattering layer and compensating the surface effect.09-15-2011
