Abstract: Embodiments of the invention generally provide a lid heater for a plasma processing chamber. In one embodiment, a lid heater assembly is provided that includes a thermally conductive base. The thermally conductive base has a planar ring shape defining an inner opening. The lid heater assembly further includes a heating element disposed on the thermally conductive base, and an insulated center core disposed across the inner opening of the thermally conductive base.

Abstract: A water vapor sensor comprises a substrate and a film of carbon nanotubes impregnated with surfactant on the substrate. The substrate is of material which is inert relative to the film. Two or more electrical conductors are in contact with in spaced apart zones of the film, whereby the impedance of the film may be measured. The sensor is housed in housing which protects the sensor but also allows exposure of the film to water vapor.

Abstract: A method for forming a fluidic ejection device is described. The method includes depositing a first layer on a silicon wafer, the first layer including a first photoresist, and exposing, at a first energy level, a portion of the first photoresist. The method also includes depositing a second layer on the first layer, the second layer including a second photoresist that is more sensitive to light than the first photoresist, and exposing, at a second energy level, a portion of the second photoresist. The second energy level is less than the first energy level. The method also includes developing unexposed portions of the first photoresist and the second photoresist to form an enclosed firing chamber and a nozzle.

Abstract: Controlling dimensions of nanowires includes lithographically forming a trench in a layer of a polymer resin with a width less than one micrometer where the polymer resin has a thickness less than one micrometer and is deposited over an electrically conductive substrate, depositing a nanowire material within the trench to form a nanowire, and obtaining the nanowire from the trench with a removal mechanism.

Abstract: A water vapour sensor comprises a substrate and a film of carbon nanotubes impregnated with surfactant on the substrate. The substrate is of material which is inert relative to the film. Two or mote electrical conductors are in contact with in spaced apart zones of the film, whereby the impedance of the film may be measured. The sensor is housed in housing which protects the sensor but also allows exposure of the film to water vapour.

Abstract: A structure for a chemical sensing device, the structure comprising at least one electrically conductive element located in, and protruding from, at least one recess. A method of manufacturing the structure includes: (a) providing a template comprising at least one recess having a recess depth; (b) providing an electrically conductive material in the at least one recess; and (c) removing part of the template to decrease the recess depth of the at least one recess, thereby forming said protruding at least one electrically conductive element.

Abstract: There is provided a wind turbine apparatus which comprises blades having an aerofoil profile. The apparatus is arranged to start up even in light wind conditions and to act as a lift type device at higher rotational speeds. The apparatus may comprise wind deflectors to concentrate wind through the apparatus. Further, the blades may be orientated at less than 90° to a radius line which leads to improved performance. Still further, the apparatus may be arranged to heat water by means of solar energy.

Abstract: A dosimeter includes a platinum-ruthenium (PtRu) nanoparticle-decorated, -coated, or -deposited carbon nanostructure element. The PtRu nanoparticle-decorated carbon nanostructure element is foulably sensitive to a gas.

Abstract: A footwear sole structure has a suspended elastomer web or mesh (1) support for a foot of a wearer of the footwear. A gap or space under the web/mesh allows it to flex down e.g. towards the outsole (3) or the ground. The web or mesh can be secured to a peripheral portion of the sole base by projections or loops (5) on the web or mesh. The web or mesh can be a one piece or multi part moulded component. The web or mesh can provide a peripheral zone around a central zone.
