High quality flake graphite is produced by methods that include mixing a carbon-containing feedstock with a catalyst to form a feedstock/catalyst mixture, or coating a catalyst with a carbon-containing feedstock, and subjecting the mixture or feedstock-coated catalyst to irradiation with a laser to convert the feedstock into flake graphite in the presence of the catalyst. In some instances, the feedstock is converted to a char by pyrolysis and the char is instead subjected to laser irradiation. The feedstock can be a biomass or a carbonaceous material. The catalyst can be an elemental metal, an alloy, or a combination thereof. In some instances, methods described herein have been found to produce high quality flake graphite in the form of potato shaped agglomerates.

The process for isolating .sup.17O from water includes: mixing .sup.17O-containing water with formaldehyde to prepare an aqueous formaldehyde solution; heating the aqueous formaldehyde solution to generate a vapor mixture containing water vapor and formaldehyde vapor; and obtaining .sup.17O-depleted water, residual formaldehyde, and a gas mixture containing hydrogen and .sup.17O-enriched carbon monoxide, through photodissociating the vapor mixture. An .sup.17O-enriched water production process includes: an operation of adding hydrogen to the gas mixture to induce a catalytic methanation reaction to synthesize methane (CH.sub.4) and .sup.17O-enriched water (H.sub.2.sup.17O) through methanation, the operation being carried out following the process for isolating .sup.17O from water.

A method of dissociating hydrogen and oxygen from a water molecule comprises isolating a predetermined volume of water between concentrically-mounted electrodes; applying a magnetic field across the predetermined volume of water, the magnetic field focused radially and attracting diametrically across the electrodes; exciting water molecules in the isolated volume of water to a resonant harmonic frequency; and synchronously applying short burst high voltage, high frequency AC pulse packets to the isolated volume of water to create an electric field. The AC pulse packets have a burst width of up to 1 millisecond and a voltage up to about 10 MV, and generate an oscillating electromotive force which acts on the excited water molecules to dissociate hydrogen and oxygen.

High quality carbon nanochains or carbon nanotubes are produced by methods that include mixing a carbon-containing feedstock with a catalyst to form a feedstock/catalyst mixture, or coating a catalyst with a carbon-containing feedstock, and subjecting the feedstock/catalyst mixture or feedstock-coated catalyst to irradiation with a laser to convert the feedstock into carbon nanochains or carbon nanotubes in the presence of the catalyst. In some instances, the feedstock is converted to a char by pyrolysis and the char is instead subjected to laser irradiation. The carbon-containing feedstock can be a biomass or a carbonaceous material. In some instances, the catalyst is a metal salt, preferably a transition metal salt. In some instances, the catalyst is an elemental metal, an alloy, or a combination thereof.
