Improvement in the efficiency of carbon dioxide reduction reaction is achieved. A gas supply unit having a plurality of pores is established in a lower portion of a reduction chamber, and carbon dioxide is supplied as bubbles into an aqueous solution. This can elevate a concentration of carbon dioxide dissolved in the aqueous solution without stirring the aqueous solution using a stirring bar, and render the concentration uniform in the aqueous solution. Therefore, the efficiency of reduction reaction of carbon dioxide in a reduction electrode can be improved.

A system and method for operating a lighting array is disclosed. In one example, the system and method detect the presence or absence of short circuiting current flow through a light emitting device and provide an indication of the same. The system and method may also increase or decrease current flow through the lighting array to compensate for reduced lighting output or to reduce the possibility of lighting array degradation.

Embodiments of the invention are directed to methods, processes, and systems for safely and reliably purifying hydrogen from a gas mixture containing hydrogen and oxygen.

The invention relates to an apparatus and methods for producing liquid colloids such as suspensions of nanoparticles, in which liquid feedstock materials are reacted on a reaction surface of a rotatable plate. The apparatus has a first plate (101) mounted for rotation about a rotation axis (102), the first plate (101) providing a reaction surface (103) having a concave portion; first (106) and second (107) inlet lines arranged to introduce respective first and second liquid feedstock materials to the reaction surface (103); and a collection unit (110) arranged to collect a reaction product formed from reaction of the liquid feedstock materials as a liquid colloid ejected from an outer edge of the plate (101).

A light source module is adapted to perform a light irradiation process on an object. The light source module includes a transparent cover, a reflector and a light emitting unit. The reflector covers the transparent cover, and the reflector and the transparent cover define a containing space. The light emitting unit is disposed inside the containing space. A perpendicular working distance from the transparent cover to the object is WD, a semi-minor axis of the reflector is A, and a semi-major axis of the reflector is B, wherein WD=2 A-3 to 3.5 A-3, and B=2 A to 2.5 A.

Described herein are systems and methods of storing and delivering electrical using hydrogen at low-cost and for long-durations. The systems and methods use energy-bearing redox pairs that electrochemically bear energy through decoupled hydrogen and oxygen consumption and/or evolution reactions, which are typically associated with fuel cells. Each species of the energy-bearing redox pair is associated with a standard electrode potential within a water electrolysis voltage window for the electrolyte solution. Electrical energy delivery, hydrogen generation, electrolyte regeneration, or combinations thereof can be performed by logically or physically separated unit operations in a continuous manner, batch manner, or semi-batch manner facilitated by the energy-bearing redox pair.

Provided herein are methods and systems for converting natural gas, and specifically methane, into higher-value oxycarbon products, such as methanol, methyl formate, and formic acid. The natural gas is introduced into an aqueous solution with hydroxyl radicals and reacted in ambient conditions to form the desired products in the presence of a metal catalyst. The methods described herein overcome the over-activation dilemma of prior art methods that lead to the formation of undesirable carbon oxide compounds. Methods and apparatus for forming hydrogen peroxide via electrolysis and for forming hydroxyl radicals from the hydrogen peroxide via reaction with ferrous ions are also provided.

Reactors subject to large variations in temperatures are subject to thermal stresses that can lead to failure or process disruption. In the present invention, reactors designs are provided that protect the reactor from thermal stress. Thermal stress can be reduced by providing expansion joints, or varying wall thickness or stiffness to adjust for thermal expansion.

A hybrid slurry reactor for performing photocatalytic reactions is provided. The hybrid slurry reactor includes a photoreactor, including a conduit, having a transparent portion, a light-emitting diode (LED) array disposed within the conduit; wherein the conduit is configured such that photons from an external source enter the conduit through the transparent portion and the LED array is directed to emit photons into the conduit.

Provided are a moisture control apparatus, a moisture control method, a program, a storage medium, a produced object, a product, an apparatus, and a facility that can improve the characteristics of an object through moisture control. In a moisture control apparatus according to one aspect of the present invention, a predetermined voltage or current including a DC component and/or an AC component is applied to at least one electrode that generates at least one of an electric field, a magnetic field, an electromagnetic field, electromagnetic waves, sound waves, and ultrasonic waves to achieve a bonded state of moisture elements in an object disposed to face the electrode, so that a property of the object is able to be improved.
