A system and method are presented for producing metallic core-shell particles. The system includes the housing having a hollow interior configured to receive and hold a molten metal input, a carrier fluid, and one or more reagents. The system also includes a shearing assembly positioned within the hollow interior of the housing. The shearing assembly is configured to, when the molten metal input, carrier fluid, and one or more reagents are held withing hollow interior and sealed within housing, shear the molten metal input into particles of an effective size so that a shell created on a surface of the particles via reaction with the one or more reagents prevents a core of the particles from solidifying when the particles are cooled to a temperature below a freezing temperature of the molten metal input.

The present invention provides an annular centrifugal contactor, having a housing to receive a plurality of liquids; a rotor inside the housing; an annular mixing zone, with a plurality of fluid retention reservoirs; and an adjustable stem that can be raised to restrict the flow of a liquid into the rotor or lowered to increase the flow of liquid into the rotor. The invention also provides a method for transferring moieties from a first liquid to a second liquid, the method having the steps of combining the fluids in a housing whose interior has helically shaped first channels; subjecting the fluids to a spinning rotor to produce a mixture, whereby the channels simultaneously conduct the mixture downwardly and upwardly; and passing the mixture through the rotor to contact second channels, whereby the channels pump the second liquid through a first aperture while the first fluid exits a second aperture.

The present invention provides a method for manufacturing a polymer by a flow-type reaction. The method includes introducing a liquid A of an anionic polymerizable monomer, a liquid B of an anionic polymerization initiator, and a polymerization terminator into different flow paths, allowing the liquids to flow in the flow paths, allowing the liquid A and the liquid B to join together, subjecting the monomer to anionic polymerization while the liquids having joined together are flowing to downstream in a reaction flow path, and allowing a solution, which is obtained by the polymerization reaction and flows in the reaction flow path, and the polymerization terminator to join together so as to terminate the polymerization reaction and to obtain a polymer having a number-average molecular weight of 5,000 to 200,000. A static mixer is disposed in the reaction flow path, and a polymer having a number-average molecular weight equal to or greater than 2,000 is introduced into an inlet port of the mixer. The present invention also provides a flow-type reaction system suitable for performing the manufacturing method.

A system for producing hydrogen gas, heat and an oxide component using a water splitting process is disclosed. The system involves a dry first chamber containing a passivating-oxide preventing reagent that receives a solid material feedstock and dissolves the solid material feedstock in the passivating-oxide preventing reagent. The passivating-oxide preventing reagent becomes saturated with the solid material in the first chamber and is then transferred to a second chamber without contact with water. In the second chamber, the solid material saturated in the passivating-oxide preventing reagent reacts with the water so as to generate hydrogen gas, an oxide component and heat. Following the reaction, the solid material depleted passivating-oxide preventing reagent and water is recycled to be re-used in the water splitting process.
