Abstract: Disclosed is a lanthanum doping catalyst for preparing carbon nanotubes having uniform diameter and producing method thereof. The catalyst comprises magnesium oxide as a support, two or three metal oxides selected from the group consisting of ferric oxide, cobalt oxide, and nickel oxide as a complex metal oxide composite, lanthanum oxide as a lanthanum doping composite, and molybdenum oxide as an enhanced catalytic composite. The catalyst is produced by dissolving magnesium salt into distilled water, and into the solution is added metal salt for forming complex metal oxide composite, lanthanum salt for forming lanthanum doping composite and salt for forming enhanced catalytic composite in a molar ratio of 0.5-3.0:0.1-1.0:0.01-1.0:0.5-3.0. The solution is dissolved completely and dried at 120-200° C. for 3-5 hours. Then, the product is calcinated at 550-850° C. for 10-30 minutes and grind to be a fine powder.

Abstract: Disclosed is a method for preparing nano-complex-powder comprising multiple components and silver. The method includes the steps of mixing 0.01-5.0% (weight percentage concentration) of silver nitrate solution with 0.001-5.0% of zinc nitrate solution, 0.001-5.0% of iron nitrate solution and 0.001-5.0% of copper nitrate solution, adding adequate amount of surfactant solution, and adding 0.001-1.0% of hydrazine hydrate gradually with stirring, and the solution is mixed for another 10-30 minutes to obtain a solution comprising multiple nano-complex-particle. After inertness, washing and drying at low temperature, the nano-complex-powder comprising multiple components and silver is obtained. The silver content in the product powder is about 40-99.6%, and the particle size is 10-100 nm.

Abstract: An insulated lattice is prepared with a plurality of lattice oriented atoms to create a substantially planar surface having a lattice arrangement. Any unsatisfied chemical bonds are terminated along the substantially planar surface by placing atoms at the site of the unsatisfied chemical bonds to terminate the unsatisfied chemical bonds and insulate the surface to form a platform. In one aspect of the invention, the insulator atoms are removed at predetermined locations. Atoms to form the atomic chain are placed at predetermined locations on the insulated lattice platform to form a first atomic chain which behaves as one of a conductor, a semiconductor and an insulator. A second atomic chain is also placed at predetermined locations on the insulated lattice platform so that the second chain behaves as another of a conductor, a semiconductor and an insulator.

These placements are made such that the second chain of atoms is electrically coupled to the first chain of atoms, and the second chain of atoms behaves differently than the first chain of atoms.

Abstract: Atomic displacement on a material surface is detected by, in a system comprising the tip of a scanning tunneling microscope (STM) and a material in question, upon an atomic displacement operation comprising extraction of atoms on the material surface and adsorption of atoms onto the material surface through application of a pulse voltage to the tip of STM, measuring a z-piezo voltage along the time series during and after application of the pulse voltage. Furthermore, heteroatoms dissociated by a reaction between the tip surface of STM and heteromolecules in a heteromolecular atmosphere are stored on the surface of the tip of STM, and then, heteroatoms are locally adsorbed onto the material surface by causing electro-evaporation of the heteroatoms through application of a prescribed scanning voltage to the tip of STM.
