A carbonized material, a device for removing ozone, and a method for removing ozone are provided. The carbonized material has at least a carbonyl-containing group, alkylol group, and carbon having sp.sup.2 hybrid orbital. In particular, the at least one carbonyl-containing group has a carbon content from 10 atom % to 30 atom %, based on the total carbon atoms of the at least one carbonyl-containing group, the at least one alkylol group, and the at least one carbon having sp.sup.2 hybrid orbital.

An exhaust purification system has a centrifuge filter, a first fan device, a second fan device, a pump, and an ozone generator. The centrifuge filter has a container having a waste gas treating area and a wastewater treating area. The first fan device communicates with and draws gas into the waste gas treating area. The second fan device communicates with and draws the gas out of the waste gas treating area. The pump communicates with and draws wastewater from the wastewater treating area. The ozone generator communicates with the pump and introduces ozone into the wastewater inside the pump. A part of the ozone dissolved in the wastewater is released to the waste gas treating area to react with the gas, and the other part of the ozone dissolved in the wastewater reacts with the wastewater.

Provided are compounds that generate a peroxide when they react with ozone in the presence of water. Additionally, alkyne compounds reactive with a free radical, a reactive oxygen species (ROS) or another reactive species are provided. Also provided are enol ether, enamine, and vinal thioester compounds reactive with a free radical, a strong acid, a reactive oxygen species (ROS) or another reactive species. Additionally provided are compounds reactive with a free radical, an ROS or another reactive species. The compounds comprise a conjugated moiety operably joined to an alkene moiety and a resonance-transmitting moiety, wherein the resonance-transmitting moiety transmits an electron through the conjugated moiety to the alkene moiety, which reacts with the free radical, an ROS or another reactive species. Also provided are methods of decomposing a free radical, an ROS or another reactive species. The methods comprise contacting the free radical or ROS with any of the above compounds. Also provided are methods of using any of the compounds described herein, and compositions comprising those compounds. Additionally provided are methods of producing the above compounds.

A system and method of abating air pollution and stimulating crop growth. A reagent is introduced to a crop canopy to neutralize air pollutants within said canopy, wherein the reagent induces an oxidation-reduction chemical reaction with the air pollution present throughout the acreage of crops, and by means of the reaction effectually neutralizes the harmful effects of the air pollutants on the crops. The reagent is diluted using a venturi valve or other means. The flow rate of said reagent is regulated using an electronic control unit, based on data collected from at least one type of sensor in the canopy that is in communication with the control unit.

Air filters formed from mats of protein-containing nanowires are provided. The nanowires are formed into a mat with pores that allow air to pass through while physically filtering particulate matter. The protein in the protein-containing nanowires also serves to chemically filter polluted air passed through the filter. Specifically, chemical functional groups from the many amino acids that comprise the protein of the protein-containing nanowire react with certain chemical pollutants (e.g., carbon monoxide and formaldehyde) in order to capture or otherwise neutralize the pollutant. Accordingly, the single nanofiber mat performs two filtering functions. Methods of filtering air using the provided air filters are also disclosed, as well as methods for making the air filters from protein-containing nanofibers.

An air separation module includes a canister having an inlet end and an outlet end arranged along a canister axis, a separator supported within the canister and arranged to separate a compressed air flow received at the air separation module into an oxygen-depleted air flow fraction and an oxygen-enriched air flow fraction, and an inlet cap. The inlet cap is seated about the inlet end of the canister, contains therein a portion of the separator, and has an oxygen-enriched air outlet port fluidly separated from the outlet end of the canister by the separator for diverting the oxygen-enriched air flow fraction to the external environment. Nitrogen generation systems and methods of making air separation modules are also described.

An apparatus and method for abating ozone and reducing sulfuric acid from an exhaust stream. In a semiconductor manufacturing plant the processing of wafers involves the cleaning and etching of wafers, the resultant processing may produce gasses which must be abated. The apparatus and method utilizes UV light in high doses to convert ozone (O.sub.3) to oxygen (O.sub.2). By ensuring laminar flow through the UV light chambers, the efficiency of the system is sufficient to allow for the remaining impurities in the exhaust air to be removed through the use of an RTO.
