Abstract: A system for generating and delivering a low temperature, wide, partially ionized tunable plasma stream is described. The system employs a fast rising, repetitive high voltage pulse generator, flowing gas, and a plasma head to produce the described atmospheric pressure plasma stream and its associated active species. The plasma head may have an exit slit with a relatively wide dimension to produce a relative wide plasma stream. Electrodes may be located proximate the exit slit, for example one in an interior of the plasma head via with gas flows toward the exit slit, and the other exterior to the plasma head and offset from the exit slit. The plasma may include baffle material to enhance a uniformity of flow through and across the exit slit. Plasma heads with having exit slit with different widths may be provided as a kit.

Abstract: A method and system to treat emissions (e.g., smoke, particulate, odor, grease) employs a nanosecond high voltage pulse generator, a transient pulsed plasma reactor, and a DC voltage source that supplies a DC bias voltage, preferably a negative DC bias voltage to a conductor of the transient pulsed plasma reactor. The system is used in a scheme that substantially reduces at least particulate matter in emissions streams, for example emissions streams produced during cooking, for instance in commercial charbroiling processes (e.g., cooking of hamburger meat), or from operation of internal combustion engines. Both a reduction in the size distribution and total particulate mass is achieved using the method and system described herein.

Abstract: A system and method for providing multiple fast rising pulses to improve performance efficiency. In one approach, multiple fast rising pulse power is employed to improve fuel efficiency and power of an engine. The system and method can involve a transient plasma plug assembly intended to replace a traditional spark plug. Alternatively, an approach involving a pulse generator and a high voltage pulse carrying ignition cable is contemplated.

Abstract: A method of conducting a Diels-Alder reaction is provided comprising reacting a Diels-Alder diene comprising a 1,3-conjugated diene with a dienophile comprising an alpha,beta-unsaturated acetal or ketal in the presence of a protonating acid to yield a [4+2] cycloadduct.

Abstract: A method is provided for making aromatic ethers by effecting the displacement of reactive radicals on an activated aromatic nucleus such as a phthalimide with a mono or bisalkali metal phenoxide in the presence of an organic solvent and a dialkylamino branched alkyl substituted pyridinium salt as a phase transfer catalyst. Improved yields of bis(aromatic ethers) are achieved without the production of undesirable by-products, such as akylated phenols.
