Submitted for the DPP10 Meeting of The American Physical Society A Simple Method to Measure the Interaction Potential between Dielectric Grains in a Dusty Plasma ZHUANHAO ZHANG, KE QIAO, JIE KONG, LORIN MATTHEWS, TRUELL HYDE, CASPER Baylor University — A simple, minimally perturbative method is introduced to experimentally measure the interaction potential between two individual dust particles,...

Plasmas are energetic media that can give birth to dust particles due to the presence of reactive gases or plasma-surface interactions. Industrial plasmas are often concerned by these dust particles that can be either unwanted or useful for the process. For fusion plasmas, production of dust particles from wall erosion is a serious issue for performance and safety reasons. In this article, some...

Understanding of various charging processes of dust grains is important in many different industrial applications as well as in the space research and theoretical studies of charging. An impact of energetic ions onto a dust grain leads to transfer of charge to the grain. This effect increases the charge of the dust grain until an equilibrium value is reached. After charging, the ion beam is swi...

Novel properties introduced by charged particulates in a plasma medium and how they influence excitation and propagation of waves are discussed. Such a medium, commonly known as dusty plasma, is generated in the near Earth environment by dust and other debris of meteoric origin and exhausts and effluents from space platforms. A novel feature of dusty plasma is that the charge to mass ratio can ...

UNLABELLED Endotoxin exposures have manifold effects on human health. The geographical variation and determinants of domestic endotoxin levels in Europe have not yet been extensively described. To investigate the geographical variation and determinants of domestic endotoxin concentrations in mattress dust in Europe using data collected in the European Community Respiratory Health Survey follow-...

We present a study of the radio emission from rotating, charged dust grains immersed in the ionized gas constituting the thick, H -emitting disk of many spiral galaxies. Using upto-date optical constants, the charge on the grains exposed to the di use galactic UV ux has been calculated. An analytical approximation for the grain charge has been derived, which is then used to obtain the grain rot...

Production of wood pellets is a relatively new and expanding industry in which the exposure profiles differ from those in other wood-processing industries like carpentries and sawmills where there are lower levels of wood dust. Sixty-eight personal exposure measurements of wood dust (inhalable and total dust) and resin acids were collected for 44 participants at four production plants located i...

The dust probe DUSTY, first launched during the summer of 1994 (flights ECT–02 and ECT–07) from Andøya Rocket Range, northern Norway, was the first probe to unambiguously detect heavy charged mesospheric aerosols, from hereon referred to as dust. In ECT–02 the probe detected negatively charged dust particles in the height interval of 83 to 88.5 km. In this flight, the lower grid in the detector...
