Abstract: Apparatus and methods are provided for quantitative detection of mercury vapor in gas samples using a film of nanoparticles. The localized surface plasmon resonance (LSPR) of an amalgam nanoparticle is sensitive to adsorbed mercury mass. The equilibrium mass of mercury on a gold nanoparticle is a function of the surrounding vapor concentration and the temperature of the gold. A device that introduces a temperature-controlled gold nanoparticle film to a controlled flow of sample gas responds predictably to a given mercury vapor concentration when optically probed in situ. Controlling the temperature of the film allows for control of adsorption and desorption rates. Equilibrium plasmonic mercury detection, described herein, removes the cycling necessary for many gold-based mercury analyses. Methods are given for the operation and analysis of the temperature-stabilized gold nanoparticle mercury sensor.

Abstract: The exposed metal tip of the strike end of an SMAW welding electrode is covered with a protective coating formed from a binder and metal particles. Because metal particles rather than graphite particles are used to provide electrical conductivity to this protective coating, flare-up of the arc when initially struck is eliminated substantially completely. In addition, the potential for weld porosity problems is also eliminated, because the metal particles of the inventive electrode do not produce CO2 as a reaction by-product which can ultimately lead to improper welding technique.

Abstract: The invention provides an improved insect bait composition comprising a boric compound, a non-sugar low molecular weight compound having a plurality of hydroxyl groups, and a foodstuff comprising a substantial amount of a soluble or semi-soluble high molecular weight polysaccharide, wherein the high molecular weight polysaccharide is in a gelled form, the composition is a sustainably soft dough, and the foodstuff contains no more than 20 weight percent of a fat or oil. The composition is suitable for extrusion, is attractive and highly toxic to insects, and has excellent resistance to hardening and spoilage during its shelf life and after pesticidal application.

Abstract: A glass patch cellular antenna is provided which can be imprinted as a thin film element on the interior surface of an automobile window. The antenna is physically configured to serve as a coupling element for an optional antenna mast which can be mounted externally on the window opposite the antenna. As a thin film element, the antenna can be factory installed and prewired such that the automobile is cellular ready, in that the installation of an external mast is unnecessary to achieve suitable performance. Yet, an external mast can be readily coupled with the antenna in order to enhance the performance capability of the antenna.
