Abstract:
Metallic nanoparticles coated with a mixed monolayer with well defined thickness or length are prepared. The mixed monolayer comprises a capture coating component useful for the specific capture of materials and a shielding coating component for elimination of non-specific binding of materials to the capture component.
Abstract:
A method of producing metal hydride misch-metal composite powders comprising providing to a rotary flow-through electrodeposition apparatus a powder whose particles comprise one or more lanthanide alloy metals selected from the group consisting of titanium lanthanide alloy metals and nickel lanthanide alloy metals; and electrodepositing one or more non-lanthanide metals on the powder via the apparatus. Also the resulting compositions of matter and metal hydride misch-metal powders.
Abstract:
A metal oxide dispersion which comprises a dispersion medium and dispersed therein a metal oxide having a particle diameter smaller than 200 nm, and which can form a thin metal film on a substrate through low-temperature heating. When the dispersion is applied to a substrate and then heated, a thin metal film is formed.
Abstract:
The invention relates to phase transfers of nanoparticles and to a catalysis using said nanoparticles. The aim of the invention is to facilitate a transfer of nanoparticles from an organic solution to an inorganic, especially, aqueous solution. To this end, a generically describable substance class, for example the commercially available 4-dimethylaminopyridine (DMAP), which is for example dissolved in water, is added to the organic solution in sufficient amounts. This measure has the effect that the nanoparticles are readily transferred in a one-step process from the organic phase (in each case in the top section) to the inorganic phase (in each case in the lower section) in the sample container.
Abstract:
A continuous method for generating substantially submicron sized metal particles in a liquid dispersion of known viscosity. Metal carbonyl gas and an inert carrier gas, with an optional dilutant gas, are introduced into a heated liquid bath wherein the metal carbonyl decomposes into submicron sized pure metal particles. The particles are suspended in the liquid. The liquid is processed to form slurries and pastes.

A complete infrastructure system for the generation (32), storage (34) transportation (35), and delivery (36) of hydrogen which makes a hydrogen ecosystem possible. The infrastructure system utilizes high capacity, low cost, light weight thermal hydrogen storage alloy materials (42) having fast kinetics. Also, a novel hydrogen storage bed design which includes a support/heat-transfer component (41) which is made from a highly porous, high thermal conductivity, solid material such as a high thermal conductivity graphitic foam. Finally a material including at least one particle having atomically engineered local chemical and electronic environments, characterized in that the local environments providing bulk nucleation.
Abstract:
A conductor or a semiconductor pattern formed on a semiconductive or nonconductive substrate by ejecting a solution, serving as a precursor of a conductor or a semiconductor and comprising a metal or composite metal oxide colloid produced by bonding a polymer compound having a function group exhibiting high physical or chemical adsorption to a metal or a metal oxide, as a protective agent, to one terminal or both terminals of a block copolymer comprising a hydrophilic block and a hydrophobic block, a compound curable upon irradiation with light, heat or electron beam energy, and a solvent, onto the surface of the substrate in a desired pattern by means of an ejector which can control ejection of an ink jet printer delicately and then irradiating a part of the substrate coated with the solution with light, heat or electron beam energy thereby hardening that part.
Abstract:
A colloidal metal solution which has a pH of 8 to 14 and contains colloidal metal particles and a low-molecular sulfur compound present as a protective colloid on the surface of the particles. The sulfur compound is, e.g., mercaptoacetic acid, mercaptopropionic acid, or mercaptoethanol. The colloidal metal solution, which has a high concentration and excellent dispersion stability imparted thereto with a small amount of a protective colloid, can be industrially and economically advantageously produced without performing an operation such as centrifugal separation.
Abstract:
A method for producing an amorphous metal, which comprises feeding a molten metal (1) into a liquid cooling medium (4) in such a manner as to cause the boiling through spontaneous formation of vapor bubble nuclei, thereby cooling the molten metal (1) rapidly while forming fine particles thereof utilizing the pressure wave induced by the boiling, to yield fine amorphous metal particles; and an apparatus for practicing the method which comprises a material feeding means (3), a cooling section (2) which introduces the cooling medium (4) in an amount being small and sufficient to cool and solidify the fed molten metal (1) and cools the molten metal (1) rapidly while forming fine particles thereof utilizing the pressure wave induced by the boiling caused through spontaneous formation of vapor bubble nuclei, to yield fine amorphous metal particles, and a recovering means (5) for recovering the fine amorphous metal particles from in the cooling medium (4). The method allows the production of an amorphous metal using a material from which conventional methods and apparatus have not been able to produce an amorphous metal, and also the production of amorphous metal particles having a size of from sub-micron order to 100 microns order, especially a few microns, which has not been achieved by conventional methods and apparatus, in good yield and in a large amount.
