Disclosed is a composite for extracting one or more metal or contaminating chemical species from an aerial or aqueous medium by selective binding, the composite including at least one porous template functionalized by at least one polymer, the polymer including one of the folowing chemical functions: primary, secondary or tertiary amine, amide, nitrile, pyridine, pyrole, thiol, thiolether, thiophene, thiadiazole, alcohol/hydroxyl, phenol, catechol, pyragalol, carboxylic acid, aldehyde, ester, acyl, crown ether, phosphate, phosphoryl, epoxide, halogen, haloalkane.

The present invention relates to an oxygenated water manufacturing device, which can be used in various fields because it can be applied to and used for not only mineral water or purified water, but also other various drinks such as tap water, barley tea, green tea, corn silk tea, and soju by using a specific configuration, which allows use of only high-purity oxygen from which ozone, which is produced with oxygen when mineral water is electrolyzed, and various inorganic substances and organic substances such as calcium (Ca), magnesium (Mg), and silicon (Si) contained in the mineral water are completely filtered out, and which completely prevents a phenomenon in which oxygen is not generated by deformation of an ion resin membrane disposed between an anode (+) and a cathode () in the oxygen generator due to a water-drying phenomenon in the hydrogen outlet.

A blower including a duct configured to allow air to flow in and out and a plurality of blades disposed to be parallel to the duct. Each of the blades including a first part, a second part, and an airflow generator configured to generate airflow in a direction from the inlet to the outlet by applying a voltage between the first electrode and the second electrode which are disposed between a first electrode on a side of the inlet, a second electrode on a side of the outlet, and a dielectric. In a cross section of the blade in the airflow direction when cut in a cross section perpendicular to each of the blades, the first part has a thickness decreasing in a direction toward the inlet and the second part has a thickness decreasing in a direction toward the outlet.

Disclosed herein are a catalyst composition, catalyst devices, and methods for removing formaldehyde, volatile organic compounds, and other pollutants from an air flow stream. The catalyst composition including manganese oxide, optionally one or more of alkali metals, alkaline earth metals, zinc, iron, binder, an inorganic oxide, or carbon.

A method and a system are provided for collecting volatile organic compounds and applying THz based detection of a signature of the collected compounds to determine egg properties. Egg properties include gender and/or fertility.

An inkjet printing apparatus includes a first stage on which a substrate is disposed, an ink storage portion including ink and a plurality of pollutant adsorption balls dispersed in the ink, a head portion including a nozzle configured to eject the ink supplied from the ink storage portion to the substrate, and a gas discharging portion disposed on a side of the ink storage portion.

A flow sensing ozone converter includes an inlet housing, an outlet housing, and an ozone converter core. The flow sensing ozone converter integrates flow sensing and oxygen removal components. The inlet housing is provided with an inlet housing flange. The outlet housing is provided with an outlet housing flange. The ozone converter core is at least partially received within the inlet housing. The ozone converter is provided with an ozone converter flange that abuts the inlet housing flange and the outlet housing flange.

An active field polarized filter includes a scrimless filter media that includes a mixture of polypropylene fibers with polymethaphenylene isophtalamide fibers. This mixture may be in the form of a nonwoven material having a weight ratio of polymethaphenylene isophtalamide fibers to polypropylene fibers ranging between 5:95 and 50:50, and even more preferably between 10:90 and 30:70.

A corona plasma cell includes a polarized electrode and a ground electrode, including a cylinder and a porous film, with the cylinder having a low profile and the polarized electrode not entering the cylinder; a corona plasma dual element including a first cell, a second cell having such a structure, which first and second cell are symmetrically arranged; and finally a plasma reactor including a plurality of cells or dual elements.

A compact lightweight air filtration system is disclosed. The air filtration system includes a hydrophobic particulate/coalescing filter and a cleanable ozone converter housed in a housing with an inlet and an outlet. Air flowing from the inlet to the outlet passes through the particulate/coalescing filter element and then the cleanable ozone converter to remove particulates, aerosols, liquids, and ozone.
