Abstract:
Separation of carbon nanotubes or fullerenes according to diameter through non- covalent pi-pi interaction with molecular clips is provided. Molecular clips are prepared by Diels- Alder reaction of polyacenes with a variety of dienophiles. The pi-pi complexes of carbon nanotrubes with molecular clips are also used for selective placement of carbon nanotubes and fullerenes on substrates.

PROBLEM TO BE SOLVED: To provide a crosslinked composition originated from living things and a manufacturing method for the same, and the structure thereof, and a manufacturing method for a printed circuit board originated from the living things using this composition. SOLUTION: A material originated from living things such as lignin, cereal oil, a wood resin, tannin, polysaccharides, and a mixture of these, etc., is cross- linked preferably using heat, a cross-linking agent and an initiator. The material thus produced has a property suitable for producing a printed circuit board. A cloth produced from glass fibers or from living things is impregnated with a mixture of the material originated from living things, the cross-linking agent, and the initiator, and then processed by a conventional method of obtain the printed circuit board.

SOLUTION: The molecule manipulator includes photoreactive molecules including a double bond and changes a cis-trans arrangement of the double bond in reaction by the irradiation by the light of the selected wavelength, and a probe with the photoreactive molecules fitted thereto, for example, a probe of a scanning proximity probe microscope. A method for manufacturing the molecule manipulator includes a step of forming a covalent bond of the photoreactive molecules with the probe. A method for moving a nano-structure includes a step of controllably holding the nano-structure by the molecule manipulator, a step of moving the nano-structure, and a step of releasing the nano-structure.

Abstract:
PROBLEM TO BE SOLVED: To prevent illegal resale by forming at least one of coat and code on an item and determining whether the item has been resold from an authorized merchant to an unauthorized merchant by checking the coat or code. SOLUTION: This identifier is extremely difficult if not impossible to remove. The identifier has its allocation and encoded code known only to a manufacturer. When the manufacturer suspects that parallel commercial transaction is occurring, he easily identifies an unauthorized reseller and can take appropriate countermeasures to prevent unauthorized activity. The system 50 includes a processor 51, a special coat/ruled code to be attached onto an item of interest and a detector 53 for determining information contents of the special coat/ scribing code. Although the detector 53 is shown separately from the processor 51, the detector can incorporate the processor therein.
Abstract:
A spin-on formulation that is useful in stripping an ion implanted photoresist is provided that includes an aqueous solution of a water soluble polymer containing at least one acidic functional group, and at least one lanthanide metal-containing oxidant. The spin-on formulation is applied to an ion implanted photoresist and baked to form a modified photoresist. The modified photoresist is soluble in aqueous, acid or organic solvents. As such one of the aforementioned solvents can be used to completely strip the ion implanted photoresist as well as any photoresist residue that may be present. A rinse step can follow the stripping of the modified photoresist.
Abstract:
The invention is directed to a method of forming carbon nanomaterials or semiconductor nanomaterials. The method comprises providing a substrate and attaching a molecular precursor to the substrate. The molecular precursor includes a surface binding group for attachment to the substrate and a binding group for attachment of metal-containing species. The metal-containing species is selected from a metal cation, metal compound, or metal or metal-oxide nanoparticle to form a metallized molecular precursor. The metallized molecular precursor is then subjected to a heat treatment to provide a catalytic site from which the carbon nanomaterials or semiconductor nanomaterials form. The heating of the metallized molecular precursor is conducted under conditions suitable for chemical vapor deposition of the carbon nanomaterials or semiconductor nanomaterials.
