The present spark plug is of the encapsulated design and facilitates the life of the spark plug, enhances the combustion process and reduces emissions. The position of an ignition chamber of the spark plug is substantially within a combustion chamber of an engine. The configuration of a parabolic end forms the ignition chamber, reduces the heat transferred to the spark plug and increases the life of the spark plug. The configuration or design of the spark plug makes the manufacturing process less costly and facilitates the combustion process by using one of a single orifice or a plurality of orifices positioned at and in a preestablished manner. The configuration will reduce or eliminate pre-ignition and other detonation problems enabling the timing to be advanced further reducing emissions.

Dispersant and foaming agent combination

The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products, a method of forming a gypsum wallboard and a gypsum wallboard. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and / or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and / or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i.e., creates void space), thereby lowering overall board weight without detrimentally affecting strength. A gypsum wallboard formed using the dispersant and foaming agent combination according to the invention exhibits a higher nail pull value than gypsum wallboard formed using a conventional dispersant and a foaming agent at the same solids loading ratio.

Method for preparing and processing a sample for intensive analysis

A method for pelletizing and taking intensive measurements of a raw sample is disclosed. The method includes homogenizing and pelletizing the sample that is to be subjected to compositional or intensive analysis. The raw sample is mixed with several solutions containing epoxies and activators based in carrier solutions or solvents, and ground to a fine powder or gel. The gel is partially dried and conformed to a pellet shape. The pellet is then cured such that the epoxy and activator solutions react and form a binding agent capable of maintaining the structural integrity of the sample pellet during intensive analysis. An intensive analysis instrument, such as LIBS, may then be used to ablate the surface of the pellet. The pellet provides consistent ablation of the sample material for accurate intensive measurements.

Fabrication of nanoscale thermoelectric devices

In a method for fabricating a nanowire thermoelectric device, a first electrode pattern is formed on a substrate, wherein the first electrode pattern includes bottom electrodes and a first set of connections which connects the bottom electrodes to form first and second groups of electrically connected bottom electrodes. P-type nanowires and n-type nanowires are selectively formed on the substrate by selectively activating either the first group of electrically connected bottom electrodes and the second group. The p-type and n-type nanowires are then connected by top electrodes. A first set of holes in the substrate is formed to remove the first set of connections. A second set of holes to allow for electrical access to the bottom electrodes, and a second set of connections are formed, so as to result in an array of thermocouples connected to each other in parallel banks of series-connected thermocouples.
