Abstract:
Hydrogen is produced by bombarding a mixture of water and heavy elements having an atomic weight of at least about 40 with fast neutrons so as to cause thermal dissociation of the water to produce hydrogen ions following elastic collision of the fast neutrons with the heavy elements. The hydrogen ions are removed from the reaction zone to prevent recombination to water, maintaining conditions which favor combination to molecular hydrogen or combination with carbon to form hydrocarbons.
Abstract:
A process is described wherein solid carbon particles C(S) of various forms are suspended in a carbon dioxide gas (CO.sub.2) and exposed to a flux of neutrons from a fusion neutron source for the purpose of converting the very high kinetic energy of the neutrons to chemically stored energy using the endothermic reaction C(S)+CO.sub.2 .fwdarw.2CO. In contrast to previous art involving the direct radiolytic dissociation of the CO.sub.2 molecule, the means described in this invention are aimed at thermally driving the reaction C(S)+CO.sub.2 .fwdarw.2CO such that a very much higher yield of CO is obtained.

Abstract:
Disclosed here is a method of fabricating a covalently reinforced carbon nanotube (CNT) assembly. The method includes producing a CNT assembly by pulling entangled CNTs from a CNT array fabricated on a substrate, the CNT assembly including a plurality of CNTs that are aligned; and creating covalent bonding between the CNTs of the CNT assembly by applying a high energy ion irradiation to the CNT assembly.

A method of synthesizing ligand-conjugated gold nanoparticles (AuNPs) is disclosed. The method comprises: a) providing an amine-modified silica particle; b) providing a solution comprising Au+3 ions; c) suspending the amine-modified silica particle in the solution comprising Au+3 ions; d) allowing the Au3+ ions to be adsorbed and/or immobilized onto the surface of the amine-modified silica particle; e) exposing the Au3+ ions immobilized onto the surface of the amine-modified silica particle to radiation to obtain bare gold nanoparticles (AuNPs) adsorbed and/or immobilized onto the surface of the amine-modified silica particle, wherein the bare AuNPs are without organic surface modifications; and f) reacting a ligand with the bare AuNPs adsorbed and/or immobilized onto the surface of the amine-modified SiNP and thereby obtain ligand-conjugated gold nanoparticles (AuNPs).

Abstract:
The present invention relates to a process for ion irradiation of a particulate substrate containing the steps of embedding particulate substrate in a solid matrix having 10B atoms, and exposing the matrix obtained in the previous step to a neutron flux to give irradiated particulate substrate. The process is extremely effective and amenable to large scale and is particularly suitable for producing irradiated nanodiamonds and irradiated SiC particles.
