A nitric oxide generator generates nitric oxide from a mixture of nitrogen and oxygen such as air treated by a pulsating electrical discharge. The desired concentration of nitric oxide is obtained by controlling at least one of a frequency of the pulsating electrical discharge and duration of each electrical discharge pulse.

In some additional aspects, an apparatus can include a chamber having an inlet valve for receiving a reactant gas and an outlet valve for delivering a product gas, a piston positioned inside the chamber and configured to move along a length of the chamber for adjusting pressure in the chamber, a sensor for collecting information related to one or more conditions of a respiratory system associated with a patient, a controller for determining one or more control parameters based on the collected information, and one or more pairs of electrodes positioned inside the chamber for initiating a series of electric arcs external to the patient to generate nitric oxide based on the determined control parameters.

An aseptic and odorless nitric oxide generator according to the present invention removes harmful materials such as ozone (O.sub.3), nitrogen dioxide (NO.sub.2) and the like, which are generated during discharge from a high-voltage discharge unit, by contacting the same with respective catalysts at a catalytic reaction unit, reduces noise, which is generated in a discharging process, by using a sound-absorbing material provided inside an exhaust pipe, and receives measured data from respective sensors provided inside the exhaust pipe so as to allow a control unit to execute and automatically operate a feedback control, thereby supplying and circulating indoors the air containing aseptic and odorless high-quality nitric oxide, and thus is very appropriate for the nitric oxide absorption by a person residing indoors through the mouth, the skin and a breathing process.

An apparatus for treating a biologic object includes a device for forming NO-containing gas flow to treat the biologic object and a plasma cooling mechanism coupled to a distal end of the device. The plasma cooling mechanism may include a cooling member and/or a cooling apparatus. The cooling member is coupled to a distal end of the device and includes a fluid conduit and a cooling chamber surrounding the fluid conduit. The cooling apparatus is coupled to a distal end of the cooling member so that the NO-containing gas flow travels from a discharge aperture formed in the device through the fluid conduit and passed the cooling apparatus before reaching the biologic object.

A NO.sub.x adsorber catalyst composition, a NO.sub.x adsorber catalyst and its use in an emission treatment system for internal combustion engines, is disclosed. The NO.sub.x adsorber catalyst composition a support material and one or more platinum group metals disposed on the support material, wherein the support material comprises a NO.sub.x storage enhancer.

A nitrogen-enriched water generator includes an elongated housing defining a sealed nitrogen/oxygen chamber in which nitrogen molecules are combined with oxygen molecules to form a nitrate (NO.sub.3) or a nitrite (NO.sub.2) gas (NOx gas). The housing includes an NOx gas and water mixing tube, a plasma generator and a nitrogen-enriched water trap. A water spray nozzle sprays water into the chamber. At least one air injection port injects air into the chamber. A vacuum port removes a volume of NOx gas not absorbed by the water from the sealed nitrogen/oxygen chamber.
