Cryogenic pellet injectors for use in fusion research have been under development at Oak Ridge National Laboratory for over 30 years. The original application of the technology was to add fuel to magnetically confined plasmas to replace D-T ions that are consumed in the fusion reactions or lost due to transport out of the confining magnetic fields. This application is still the primary use for pellet...
The limited global crude oil reserve coupled with the environmental worsening caused by the excessive consumption of petroleum-derived fuels, has forced human to look for alternative sources of energy. Ethanol, both renewable and environmentally benign, is regarded as one of the best alternatives. In this paper, we summarize the advance in bioethanol processing from various raw materials such as sugars,...
AC gliding arc reactor producing syngas (H2+CO) for partial oxidation of methane in an atmospheric gliding arc discharge has been designed and constructed. In this case, no catalysts are used to assist reforming; the plasmas play a role as catalyst and provide the energy for such reactions. The oxygen in the air is used for the partial oxidation of methane. The methane conversion and the energy efficiency...
Summary form only given. Lawrenceville Plasma Physics Inc. has initiated a two-yearlong experimental project to test the scientific feasibility of Focus Fusion, controlled nuclear fusion using the dense plasma focus (DPF) device and pBll fuel. The experiment is being conducted with a newly-constructed dense plasma focus, Focus-Fusion-1, which is expected to generate peak currents in excess of 2 MA...
The thorium fuel cycle fissile and fusile breeding in a molten salt and a solid fuel blanket for a system consisting of fusion fuel factories coupled to fission satellites burners, is considered. The use of the thorium cycle in a fusion fission hybrid could bypass the stage of fourth generation fission breeder reactors in that the energy multiplication in the fission island allows the satisfaction...
Microtechnology or microelectromechanical systems (MEMS) is a viable and promising method to facilitate such highly compact power sources through the integration of a fuel cell with all operation units of a fuel processor. Using microtechnology to process high-density hydrocarbon fuels appears to be an encouraging method to supply hydrogen fuel for feeding portable fuel cells. In addition, microtechnology...
This paper reviews the various methods of hydrogen production for automotive applications. First, a summary of different methods of hydrogen production which are used in various industries have been given. The major focus of this paper is on non-thermal or cold plasma for hydrogen generation. Physical characteristics of cold plasma, as well as various methods of plasma generation and their characteristics...
The purpose of this study was to explore the time course of cerebral lactate concentration in ischemic rat brain after sacrifice, in which area the morphology signal was still normal in the early phase. Ischemic rat model was used in this study. Eighty rats were fasted overnight before sacrifice and divided into 16 groups randomly. Lactate concentration was measured by using LD kit. Results showed...
