A solar-driven methanol reforming system for hydrogen production includes a water storage tank, high-temperature solar collector tubes, a thermocouple, valves, preheaters, an evaporator, a reactor, a heat exchanger, a mixed solution (methanol and water) storage tank, a gas separator, a pump, a carbon dioxide storage tank, a hydrogen storage tank, and pipes; the present invention utilizes solar energy to provide heat required for hydrogen production by methanol reforming, and stores some heat in a phase change material to supply heat for the methanol reforming reaction when sunlight is weak; the system does not need additional energy supply, thus saving energy consumption from traditional electric heating or fuel heating.

A graphene manufacturing device using Joule heating includes: a chamber having a space provided therein so as to synthesize graphene; and a first roller portion and a second roller portion disposed inside the chamber to be spaced from each other such that same support a catalyst metal penetrating the interior of the chamber and are supplied with an electric current for graphene synthesis, thereby Joule-heating the catalyst metal. In order to compensate for a temperature deviation of the catalyst metal passing between the first roller portion and the second roller portion, a first area of the catalyst metal, which is close to the first roller portion, and a second area of the catalyst metal, which is close to the second roller portion, are disposed to have movement paths facing each other.

A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.

The present disclosure provides a gas injection system that can include a housing configured to hold a plurality of precursor cartridges comprising one or more precursor materials, and a nozzle extending from the housing, the nozzle having a tip configured for insertion into a sample chamber of a material processing apparatus. The precursor cartridges are fluidly connected to the nozzle to selectively deliver one or more precursor gasses to the sample chamber.

A method of fabricating a catalytic reactor assembly having an outer tube and an inner tube is provided. The method may include inserting a catalyst into the outer tube and inserting the inner tube through the catalyst. The method may further include radially expanding the inner tube against the catalyst.

Disclosed are a method for manufacturing hydrogen microbubbles (A1) and a device (10) thereof. The device comprises air pressure assembly (1) and a water container (2), wherein the water container (2) is loaded with water (A).
