TL;DR: In this paper, a process for producing stable, radiation hard, highly conductive polymers by a combination of chemical doping and ion irradiation and microelectronics is described, which may contain regions of different kinds of conductivity on the same polymer.

TL;DR: A system for determining depth profiles of concentrations of hazardous elements in soils comprises a neutron source for generating neutrons of a first energy level and irradiating a volume of soil with the neutrons Nuclear reactions are effected within the soil and gamma radiation is emitted from the soil as discussed by the authors.

TL;DR: In this article, x-rays, thermal neutrons or laser beams are directed at a slurry as it flows through a flow cell to induce emission of secondary x-ray, gamma rays or light, respectively, characteristic of the heavy metal contaminants and constituents representative of the solids contents of the slurry.

TL;DR: In this article, the authors proposed a method of reducing the switching time of certain semiconductor devices and particularly gain-operated semiconductor device by adjusting the energy level of the radiation source to provide the depth of maximum defect generation adjacent a blocking PN junction.

TL;DR: In this paper, the minority carrier lifetime control by electron irradiation has been developed into a reliable manufacturing process for power devices and the approximate location of these recombination centers in the forbidden gap and their densities are obtained by the thermally stimulated current method.
