Systems and methods for preparing and dispersing dry powders are disclosed herein. The system includes a powder feeder, a rotating holder or disc configured to receive an input powder from the powder feeder, and one or more ultrasonic transducers. The ultrasonic transducer is configured to create standing waves, which suspend the input powder within a space above the rotating holder disc for collection and subsequent processing and/or use. Also disclosed herein is an adapter configured to fit existing off-the-shelf powder dispensers that includes an ultrasonic transducer configured to suspend an input powder in midair for collection.

A microsphere cavity that forms a whispering gallery mode is used. By vibrationally coupling a whispering gallery mode being one of kinds of an optical mode to a vibrational mode of water or a liquid other than water, ultra strong coupling water or a liquid in a vibrational coupling state is generated. A first example is to acquire aerosol in which water itself or a liquid itself other than water constitutes a micro-water sphere cavity or a micro-liquid sphere cavity (50) and is a dispersoid. A second example is to acquire colloid or emulsion in which a micro-dielectric sphere cavity (53) is a dispersoid and water or a liquid other than water is a dispersion medium.

Provided are an apparatus and a method for manufacturing high-pressure method low-density polyethylene, the apparatus and the method having excellent characteristics that the amount of smoke generated during processing of a polyethylene to be obtained is small, and the number of fish eyes contained in a film formed from the polyethylene is small. An apparatus for manufacturing high pressure method polyethylene includes: an ethylene supply line that is a line branched from a high pressure recycle ethylene line and connected to a recycle ethylene holding drum for decompressing high pressure recycle ethylene from the high pressure recycle ethylene line and supplying the decompressed recycle ethylene to the recycle ethylene holding drum; and the recycle ethylene holding drum that is a drum for holding the decompressed recycle ethylene through the ethylene supply line.

A methane production system comprises: a reaction tank that produces methane and water by reacting CO and/or CO.sub.2 supplied to the reaction tank with hydrogen; a cleaning tank that is located at an upstream side of the reaction tank in a supply direction of the CO and/or CO.sub.2, and removes water-soluble impurities from a raw material gas including the CO and/or CO.sub.2 and the water-soluble impurities by bringing the raw material gas into contact with water; and a first supply line that supplies the raw material gas from which the water-soluble impurities are removed from the cleaning tank to the reaction tank; and a second supply line supplies water produced in the reaction tank from the reaction tank to the cleaning tank to bring the produced water into contact with the raw material gas in the cleaning tank.

The invention is directed to a chemical reactor (100) having (a) two or more gas reactor elements (12) with each gas reactor element (12) having (i) a first reaction chamber (38), and (ii) a feed assembly unit (36), (b) a second reaction chamber (20) coupled with each of the two or more gas reactor elements (12) and configured to independently receive two or more product streams from the two or more gas reactor elements (12); and optionally, (c) a gas converging section (40) located downstream to the second reaction chamber (20). The invention is further directed to a method of producing chemical products using the chemical reactor (100) of the present invention.

The present disclosure relates to a standalone precursor for synthesizing nanomaterials, which is capable of effectively mass-producing nanomaterials, and an apparatus for synthesizing nanomaterials using the same.

Provided is a method of producing isolated graphene sheets, comprising: (a) providing a reacting slurry containing a mixture of particles of a graphite or carbon material and an intercalant and/or an oxidizing agent; (b) providing one or a plurality of flow channels to accommodate the reacting slurry, wherein at least one of the flow channels has an internal wall surface and a volume and an internal wall-to-volume ratio of from 10 to 4,000; (c) moving the reacting slurry continuously or intermittently through at least one or a plurality of flow channels, enabling reactions between the graphite or carbon particles and the intercalant and/or oxidant to occur substantially inside the flow channels to form a graphite intercalation compound (GIC) or oxidized graphite (e.g. graphite oxide) or oxidized carbon material as a precursor material; and (d) converting the precursor material to isolated graphene sheets.
