| 20080213567 | HETERO-JUNCTION MEMBRANE AND METHOD OF PRODUCING THE SAME - Provided is a hetero-junction membrane including: a first layer comprising first nanoparticles of a first conductive type; and a second layer comprising second nanoparticles of a second conductive type, wherein the first layer and the second layer are joined to each other. The hetero-junction membrane has advantages in that actuating efficiency is much higher, the direction of actuating can be predicted and the manufacturing processes are simple compared to conventional bucky paper formed of a single layer. | 09-04-2008 |
| 20090123649 | METHOD OF MANUFACTURING SILICON NANOTUBES USING DOUGHNUT-SHAPED CATALYTIC METAL LAYER - Provided is a method of manufacturing silicon nanotubes including forming non-catalytic metal islands on a substrate; forming catalyst metal doughnuts to surround the non-catalytic metal islands; and growing silicon nanotubes on the catalyst metal doughnuts. The silicon nanotubes are efficiently grown using the catalyst metal doughnuts. | 05-14-2009 |
| 20090294762 | COMPOUND HAVING THIOL ANCHORING GROUP, METHOD OF SYNTHESIZING THE SAME, AND MOLECULAR ELECTRONIC DEVICE HAVING MOLECULAR ACTIVE LAYER FORMED USING THE COMPOUND - Provided are an electron donor-azo-electron acceptor compound having a thiol-based anchoring group, a method of synthesizing the compound, and a molecular electronic device having a molecular active layer formed of the compound. The compound for forming a molecular electronic device includes an azo compound that has a dinitrothiophene group and an aminobenzene group having thiol derivatives. The compound forms a molecular active layer in the molecular electronic devices. The molecular active layer is self-assembled on an electrode using the thiol derivative in the azo compound as an anchoring group.
