摘要:
A Fischer-Tropsch process including the steps of providing a reactor having a substrate element with a surface and a plurality of elongated micro-structures of catalyst material attached to the substrate surface The catalyst material includes at least one of cobalt, iron, or ruthenium and the micro-structures have a width of less than about 1 um and a length at least five times the width. A carbon compound and hydrogen are injected into the reactor such that at least a portion of the carbon compound and hydrogen contact the catalyst material. The carbon compound and hydrogen are reacted with the catalyst at a temperature between about 150° F. and about 400° F.
摘要:
In at least one implementation, a vehicle wiper control system includes an actuator and a controller. The actuator is coupled to the wiper and operable to selectively move the wiper from a normal operating position engaged with a vehicle surface to be wiped and to a deployed position not engaged with said vehicle surface. The controller is communicated with the actuator and with a source of weather information regarding one or more weather factors, the controller being operable to cause the actuator to move the wiper from its normal position to its deployed position when one or more of the weather factors are at or beyond a threshold for said one or more weather factors. This may cause, for example, a wiper blade to be moved off of a vehicle surface if the current or predicted weather is indicative of possible snow fall or ice formation.

On-chip microplasma discharge devices capable of producing light, including ultraviolet light, capable of detecting atomic and molecular gas, and capable of detecting atomic and molecular contaminants in water samples. The on-chip microplasma discharge devices utilize nanoparticles or magnets to tune or confine microplasma discharges generated by electrodes delivering a voltage to the device. Selective control of the gaseous pressure at a value between atmospheric pressure and a vacuum pressure allows for further refinement of gas or contaminant detection, or for further tuning of the wavelength of the light to be produced.

Microfabricated, gas-filled radiation detector assemblies, methods of making and using same and interface circuit for use therewith are provided. The assembly includes a micromachined radiation detector including a set of spaced-apart electrodes and an ionization gas between the electrodes. A housing has a chamber for housing the detector including the gas. The housing of the assembly also includes a window which allows passage of charged particles therethrough to ionize the gas to create electrons which, in turn, create an electron cascade in the gas between the electrodes when the set of electrodes is biased.
