Process for making silver metal filaments

Title: Process for making silver metal filaments

Abstract

A process for making silver metal particles from silver salt particles having the same morphology. Precursor silver salt particles selected from the group consisting of silver acetate and silver sulfide having a selected morphology are contained in a reactor vessel having means for supporting the particles in an air suspension to prevent the agglomeration of the particles. Air is flowed through the reactor vessel at a flow rate sufficient to suspend the particles in the reactor vessel. The suspended precursor silver salt particles are heated to a processing temperature and at a heating rate below which the physical deterioration of the suspended precursor silver salt particles takes place. The suspended precursor silver salt particles are maintained at the processing temperature for a period of time sufficient to convert the particles into silver metal particles having the same morphology as the precursor silver salt particles.

Process for making surfactant capped metal oxide nanocrystals, and products produced by the process

Patent Alivisatos, A. Paul; Rockenberger, Joerg

Disclosed is a process for making surfactant capped nanocrystals of metal oxides which are dispersable in organic solvents. The process comprises decomposing a metal cupferron complex of the formula M^XCup_X, wherein M is a metal, and Cup is a N-substituted N-Nitroso hydroxylamine, in the presence of a coordinating surfactant, the reaction being conducted at a temperature ranging from about 150 to about 400.degree. C., for a period of time sufficient to complete the reaction. Also disclosed are compounds made by the process.

Methods for making and processing metal targets for producing Cu-67 radioisotope for medical applications

Patent Ehst, David A.; Bowers, Delbert L.

The present invention provides a method for producing Cu67 radioisotope suitable for use in medical applications. The method comprises irradiating a metallic zinc-68 (Zn68) target with a high energy gamma ray beam. After irradiation, the Cu67 is isolated from the Zn68 by any suitable method (e.g., chemical and/or physical separation). In a preferred embodiment, the Cu67 is isolated by sublimation of the zinc (e.g., at about 500-700° C. under reduced pressure) to afford a copper residue containing Cu67. The Cu67 can be further purified by chemical means (i.e., dissolution in acid, followed by ion exchange).

Polymer composites for fused filament fabrication and methods of making the same

Patent Erikson, Rebecca L.; Christ, Josef F.; Kennedy, Zachary C.; ...

Disclosed are compositions of a fused filament fabrication (FFF) composite filament having embedded functional materials in a thermoplastic matrix. Methods of making the composite filaments are also disclosed. In one example, a FFF composite filament incorporates a MOF, in an amount greater than 10% by mass, dispersed in a matrix polymer. One example of a method of synthesizing FFF composite filaments involves mixing a suspension that has a MOF with a matrix polymer solution to yield a polymer-MOF mixture. The mixture is cast and dried into a solid composite material, which is formed a FFF composite filament having the MOFmore » in an amount greater than 10% by mass. « less

Method of making a carbon filament for thermal ionization

Patent Mannion, Joseph M.; Achey, Randall M.

A method for modifying a carbon thermal ionization filament is disclosed. In particular, the method requires a step of reacting a fluorine-containing compound with the carbon thermal ionization filament to provide a fluorinated carbon thermal ionization filament. Such method can result in a fluorinated carbon thermal ionization filament that can be employed in a system, such as a thermal ionization mass spectrometer, for ionizing a sample.
