Highly dispersed colloidal gold (Au) nanoparticles were synthesized at room temperature using glow discharge plasma within only 5 min. The prepared Au colloids were characterized with UV-visible absorption spectra (UV-vis), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) equipped with an energy dispersion X-ray spectrometer (EDX). UV-vis, XPS and EDX results c...

A plasma polymerization process using a continuous glow discharge has been implemented for preparing proton conducting membranes from trifluoromethane sulfonic acid and styrene. The chemical and physical structure of plasma membranes has been investigated using FTIR and SEM. The films are homogeneous with a good adhesion on commercial gas diffusion layer (E-Tek). Their deposition rate can be in...

Submitted for the GEC08 Meeting of The American Physical Society Sorting Category: 2.6 (E) Arguments for increased efficiency of Xe excimer DBDs by pulsed instead of sinusoidal excitation MARK PARAVIA, KLAUS E. TRAMPERT, MICHAEL MEISSER, WOLFGANG HEERING, Light Technology Institute, University Karlsruhe — Xenon excimer dielectric barrier discharges are used as VUV sources or as plane light sour...

In many species, males rely on sexual ornaments to attract females. Females, by contrast, rarely produce ornaments. The glow-worm (Lampyris noctiluca) is an exception where wingless females glow to attract males that fly in search of females. However, little is known about the factors that promote the evolution of female ornaments in a sexual selection context. Here, we investigated if the fema...

Plasma induced flow field modification is studied experimentally using non-equilibrium DC surface discharge in a Mach 3 supersonic flow. An array of small pin electrodes (φ = 3/32”) is used in streamwise plasma discharge configuration. The schlieren imaging shows that an oblique shock can be obtained with a volumetric glow discharge on the cathode with a relatively low current (as low as 50 mA)...

The phosphate glass samples doped with Tb2O3 oxide (general formula: P2O5-Al2O3-Na2O-Tb2O3) were synthesized and studied for usage in high-dose radiation dosimetry (for example, high-activity nuclear waste disposals). influence of terbium concentration on thermoluminescent (TL) signals was analyzed. TL properties glasses investigated using various experimental techniques such as direct measurem...

Abstract In this work we performed experimental analyses of the dose-response curves natural alexandrite, using thermoluminescence (TL) and optically stimulated luminescence (OSL). The alexandrite crystals from Bahia, Brazil, were pulverized optical absorption measurements carried out in range 200 to 800 nm, comparing a non-irradiated sample with 10 Gy beta irradiated one. OSL TL Risø equipment...

Consumers are frequently presented opportunities to purchase products that are linked to charitable causes, green production, or fair trade practices. In Elfenbein and McManus (forthcoming) we demonstrate that consumers are willing to pay a premium for these items by analyzing a hand-matched data set of identical items sold in charity and non-charity auctions on eBay. This premium may occur bec...

Many real-time algorithms for mesh deformation driven by animation of an underlying skeleton make use of a set of per-bone weights associated with each vertex. There are few unguided algorithms for the assignment of these weights with a recent proposed solution being bone heat [1]. In this paper, we briefly discuss bone heat and provide examples where it performs poorly. We then develop a refin...

INTRODUCTION The development of syndromic surveillance systems to detect bioterrorist attacks and emerging infectious diseases has become an important and challenging goal to many governmental agencies and healthcare authorities. This study utilized the sharp increase of glow product-related calls to demonstrate the utility of poison control data for early detection of potential outbreaks durin...
