A sensor for detecting a first component in a gas mixture is disclosed having a gas-sensitive electrode and a catalyst which is arranged on and/or spaced apart from the electrode in a porous carrier ceramic. The catalyst has the effect that a second component in the gas mixture is chemically altered such that the component contributes to no substantial change in the potential of the electrode.

A method for producing at least one porous layer on a substrate, whereby a suspension, which contains particles from a layer-forming material or molecular precursors of the layer-forming material, as well as at least one organic component, is applied to the substrate, the precursors of the layer-forming material are subsequently reacted to produce the layer-forming material following application to the substrate, in a next step, the particles from the layer-forming material are sintered, and the at least one organic component is subsequently removed. Also, a field-effect transistor having at least one gate electrode, the gate electrode having an electrically conductive, porous coating which was applied in accordance with the method.

The present invention is a television set that is operated by voice commands without the use of a remote control as is typical in the art. The device also is multifunctional in combining television viewing capabilities, with voice telephone sending and receiving capabilities, digital video recording capabilities and weather alert indications. All of these functions are combined into a single device. The present invention makes improvements on those known in the art by eliminating the need for any second control device (e.g. remote control) and combining many devices into a single device that can be controlled by the user's voice commands.

Improved microemulsions having a lower level of solvent, a lower level of oil, a more robust formulation and/or exhibiting equivalent if not better performance on fatty soils can be obtained by simultaneous selection of specific surfactants, specific oils and specific solvents. When all three of these components are selected in the manner described herein, a synergistic benefit is attained. The present invention provides a liquid, aqueous cleaning composition in the form of a stable emulsion having a dispersed phase diameter of 10-100 nanometres comprising: a) at least 30 wt % water, b) at least l wt % but not more than 40 wt % of a surfactant system comprising at least one alkoxylated alcohol nonionic surfactant and not more than 10 wt % on alkoxylated alcohol nonionic surfactant of anionic surfactant, c) at least 2 wt % but not more than 20 wt % of a solvent having a solubility of less than 12% w/w in water, and, d) at least 0.2 wt % but less than 10 wt % of a substantially water-insoluble oil which is a solvent for fats.

An apparatus for detecting at least one substance present in a fluid flow includes at least one field effect transistor which acts as a measuring sensor, and at least one field effect transistor which acts as a reference element, the field effect transistors each having at least one source electrode, one drain electrode, and one gate electrode. The gate electrode of the field effect transistor which acts as the measuring sensor is sensitive to the at least one substance to be detected, and the gate electrode of the field effect transistor which acts as the reference element is essentially insensitive to the at least one substance to be detected. The source electrode of one of the field effect transistors and the drain electrode of the other of the field effect transistors are connected to one another and to a signal line. A method for detecting at least one substance present in a fluid flow by using the apparatus is also described, a potential of 0 volt being applied to the signal line and the current flowing on the signal line being measured.
