The goal of this project is the study of the electrical breakdown, due to microwaves, which occurs on the surface of vacuum/atmosphere interfaces. This is a final report for AFOSR Grant No. 88-0102, that began in January, 1988. This report, however, will concentrate on the results since ...
Extensive studies of microwave breakdown in gases revealed complex discharge dynamics accompanied by plasma production and generation of gas breakdown waves8,9. The analogy between a vacuum pair production and a gas ionization, as well as between a vacuum breakdown via QED cascading and a gas ...
During the coal combustion process, some elements will be released into the atmosphere or be left in the cinder, which causes air, water, and land pollution. For example, N and S elements in coal participate in several reactions and then will be released into the atmosphere, which makes ...
Results are reported for an experimental study of the reflection from acoustic-cavity walls of shock waves produced during laser-produced breakdown of various gases and solid surfaces. The experiments were performed with the aid of a Q-switched Nd laser, He and Ar gases in quartz spherical shells...
In order to slow the greater heating trend, she explained, humans need to reduce carbon emissions from the burning of fossil fuels. "The long-term trajectory is that as long as we continue to emit pollution into our atmosphere, these greenhouse gases, you know, temperatures...
influential magazine Science named U.S. moves to get things backwards in tackling climate change as a breakdown of the year. The U.S. government has forged ahead with a range of policies that make it more difficult for the United States and the world to curb emissions of greenhouse gases....
fugacities, close to the hematite-magnetite buffer, that can contain significant amounts of sulfate. The migration of these fluids from the slab to the mantle wedge could therefore provide the oxidized source for the genesis of primary arc magmas that release gases to the atmosphere during ...
A high average charge density up to 2.38 mC m−2 is achieved using the 4 μm PEI film and homemade carbon/silicone gel electrode in ambient atmosphere with 5% relative humidity. This work also reveals the actual charge density (over 4.0 mC m−2) in a TENG electrode based on ...
