Three dimensionally periodic structural assemblies on nanometer and longer scales

This invention relates to processes for the assembly of three-dimensional structures having periodicities on the scale of optical wavelengths, and at both smaller and larger dimensions, as well as compositions and applications therefore. Invention embodiments involve the self assembly of three-dimensionally periodic arrays of spherical particles, the processing of these arrays so that both infiltration and extraction processes can occur, one or more infiltration steps for these periodic arrays, and, in some instances, extraction steps. The product articles are three-dimensionally periodic on a scale where conventional processing methods cannot be used. Articles and materials made by these processes are useful as thermoelectrics and thermionics, electrochromic display elements, low dielectric constant electronic substrate materials, electron emitters (particularly for displays), piezoelectric sensors and actuators, electrostrictive actuators, piezochromic rubbers, gas storage materials, chromatographic separation materials, catalyst support materials, photonic bandgap materials for optical circuitry, and opalescent colorants for the ultraviolet, visible, and infrared regions.

Multiple tape laying apparatus and method

A fully automated method and apparatus is disclosed to laminate various structural articles with multiple layers of a resin impregnated fiber tape. The fiber tape is deposited with a tape laying member moving alternately in different travel directions. The tape laying member removes all backing layers from the tape being employed, then deposits the unbacked tape on the surface of the structural article and finally severs the end of the tape being deposited. An automated cut and restart procedure is employed in the present apparatus to increase throughput.

Method for making a nano-stamp and for forming, with the stamp, nano-size elements on a substrate

The stamping process and a method of fabrication of nano-stamps with characteristic dimensions below 1 nm and up to 100 nm intended for usage in making patterns of characteristic dimensions the same as those of the nano-stamp on surface of a substrate is provided. In the process a very hard stamp is fabricated by first depositing alternating layers of two materials, one of which has very high hardness, on some sacrificial substrate via PVD, CVD or any other deposition procedure that produces alternating layers of selected thickness, from sub 1 nm to above 100 nm. The layered film is then polished to an atomically smooth finish perpendicular to the plane of the layers and etched to produce dips in the softer layers. These steps produce a grid of parallel elevations and valleys on the etched surface, which now can be used as a stamp to stamp out patterns on a substrate of lower hardness than the hardness of the elevated layers. If the substrate is stamped twice with a turning of the stamp 90 degrees between first and second stampings, a square pattern of elevations or hills and valleys is formed, which can be used for magnetic memory storage by subsequently sputtering magnetic material on the tops of the elevations or hills.

Electroless plating processes

The invention includes processes for combined polymer surface treatment and metal deposition. Processes of the invention include forming an aqueous solution containing a metal activator, such as an oxidized species of silver, cobalt, ruthenium, cerium, iron, manganese, nickel, rhodium, or vanadium. The activator can be suitably oxidized to a higher oxidation state electrochemically. Exposing a part to be plated (such as an organic resin, e.g. a printed circuit board substrate) to the solution enables reactive hydroxyl species (e.g. hydroxyl radicals) to be generated and to texture the polymer surface. Such texturing facilitates good plated metal adhesion. As part of this contacting process sufficient time is allowed for both surface texturing to take place and for the oxidized metal activator to adsorb onto said part. The part is then contacted with a reducing agent capable of reducing the metal activator to a lower ionic form, or a lower oxidation state. That reduction can result in the formation of metallic catalytic material over the surface of the part. The reduced metal activator can then function to catalyze the electroless deposition of metal such as copper from solution by contacting the part with the plating solution.

Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a particle packed, highly inorganically filled, cellular matrix are disclosed. Suitable inorganically filled mixtures are prepared by mixing together a starch-based binder, a solvent, inorganic aggregates, and optimal admixtures, e.g., fibers, mold-releasing agents, rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The inorganically filled mixtures have a predetermined viscosity and are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled cellular, structure matrix. The molded articles may be placed in a high humidity chamber to obtain the necessary flexibility for their intended use. The articles may be manufactured to have properties substantially similar to articles presently made from conventional materials like paper, paperboard, polystyrene, plastic, or other organic materials. They have especial utility in the mass-production of containers, particularly food and beverage containers.
