            <description><![CDATA[A single layer capacitive device including a portion of pre-fired ceramic material and one or more terminations is formed with manufacturing steps that are easily modified to customize size and other aspects of such devices. The single layer devices may be utilized by themselves or selectively combined with MLCs to form integrated capacitor assemblies yielding many desirable performance characteristics in a monolithic assembly. An exemplary integrated capacitor assembly advantageously provides customized frequency response and capacitance in limited real estate. Predictable and generally constant or “flat” impedance versus frequency is afforded mainly by the properties of the single layer device, while higher capacitance is provided mainly from features of one or more associated MLCs. High structural integrity of exemplary integrated capacitor assemblies is achieved due to the disclosed attachment methods. Exemplary integrated capacitor assembly embodiments of the presently disclosed technology have been found to provide effective DC blocking from 20 kHz to 40 GHz.]]></description>

            <description><![CDATA[Granulated Activated Carbon (GAC) is used to remove hydrogen sulfide (H 2 S) from the biogas produced in an anaerobic digester. The cleaned biogas is then combusted in a reciprocating engine. The exhaust of the engine is passed through a heat exchanger and then through GAC in an adsorber to adsorb nitrogen oxides (NOx) and any sulfur oxides (SOx). The GACs containing NOx, H 2 S, and SOx, are transported to a microwave reactor, mixed, and exposed to microwave energy. The H 2 S and NOx are desorbed from the GAC and chemically combined to produce nitrogen, carbon dioxide, sulfur and water. Unreacted nitrogen oxides or hydrogen sulfide are transported to a second reactor containing carbon media to be reacted by a further microwave process. Sulfur is removed with a filter as a solid and the remaining inert components are vented to the atmosphere. The GAC is regenerated and reused to remove additional H 2 S and NOx.]]></description>

When such a two-step initial treatment operation is carried out, the stabilized sensor sensitivity performance is achieved.]]></description>
