A semiconductor 100 has a P⁻ body region and an N⁻ drift region in the order from an upper surface side thereof. A gate trench and a terminal trench passing through the P⁻ body region are formed. The respective trenches are surrounded with P diffusion regions at the bottom thereof. The gate trench builds a gate electrode therein. A P⁻⁻ diffusion region, which is in contact with the end portion in a lengthwise direction of the gate trench and is lower in concentration than the P⁻ body region and the P diffusion region, is formed. The P⁻⁻ diffusion region is depleted prior to the P diffusion region when the gate voltage is off. The P⁻⁻ diffusion region serves as a hole supply path to the P diffusion region when the gate voltage is on.

Fully lipid-encapsulated therapeutic agent particles of a charged therapeutic agent are prepared by combining a lipid composition containing preformed lipid vesicles, a charged therapeutic agent, and a destabilizing agent to form a mixture of preformed vesicles and therapeutic agent in a destabilizing solvent. The destabilizing solvent is effective to destabilize the membrane of the preformed lipid vesicles without disrupting the vesicles. The resulting mixture is incubated for a period of time sufficient to allow the encapsulation of the therapeutic agent within the preformed lipid vesicles. The destabilizing agent is then removed to yield fully lipid-encapsulated therapeutic agent particles. The preformed lipid vesicles comprise a charged lipid which has a charge which is opposite to the charge of the charged therapeutic agent and a modified lipid having a steric barrier moiety for control of aggregation.

The selective catalytic reduction of nitrogen oxides (especially NO and NO₂) in exhaust from diesel and other lean burn engines is improved by use of a compact hyperplasma reactor for generating ozone and other highly oxidizing species in a stream of air. A portion of the ozone containing air stream is blown directly into the exhaust for oxidizing NO to NO₂. The other portion of plasma treated air is used to fractionate and reform a volume of diesel fuel to produce low molecular weight hydrocarbons and oxidized hydrocarbons to be added to the exhaust as NO₂ reductants in the catalytic reduction.
