Patent number: 8735176Abstract: The present invention relates to a metal oxide nano-composite magnetic material, fabrication method, and method for linkage, enrichment, and isolation of phosphorylated species. The metal oxide nano-composite magnetic material comprises the magnetic iron oxide nanoparticle, a silica layer immobilized onto the magnetic iron oxide nanoparticle and a metal oxide layer coated onto the silica layer. The magnetic iron oxide nanoparticles can be used for absorbing microwave radiation to accelerate the enrichment and linkage for phosphorylated species onto the metal oxide nano-composite magnetic material. Furthermore, the magnetic property of magnetic iron oxide nanoparticles leads to isolation of the metal oxide nano-composite magnetic material-target species conjugates by simply employing an external magnetic field.Type: GrantFiled: April 11, 2008Date of Patent: May 27, 2014Assignee: National Chiao Tung UniversityInventors: Yu-Chie Chen, Cheng-Tai Chen, Wei-Yu Chen, Chun-Yuen Lo, Hong-Yi Lin, Chih-Chi Liu

Patent number: 8573876Abstract: A ring binder mechanism for retaining loose-leaf pages securely holds closed ring members together to prevent inadvertent loss of pages retained by the mechanism. The mechanism comprises a housing supporting two hinge plates for pivoting motion to open and close paired ring members mounted on the plates. Free ends of the paired ring members have interlocking configurations that securely join together when the ring members close. The configurations prevent misalignment of the closed ring members in all directions transverse to longitudinal centerlines of the ring members. The mechanism also includes locking elements that interact with the hinge plates to block their pivoting motion when the ring members are closed. This holds the free ends of the closed paired ring members together so that the interlocking configurations of the ring members remain interengaged.Type: GrantFiled: March 15, 2005Date of Patent: November 5, 2013Assignee: World Wide Stationery Manufacturing Company, LimitedInventors: Hung Yu Cheng, Ho Ping Cheng, Chun Yuen To
