Abstract:
Work from several laboratories has shown that metal nanofilaments cause problems in some molecular electronics testbeds. A new testbed for exploring the electrical properties of single molecules has been developed to eliminate the possibility of metal nanofilament formation and to ensure that molecular effects are measured. This metal-free system uses single-crystal silicon and single-walled carbon nanotubes as electrodes for the molecular monolayer. A direct Si-arylcarbon grafting method is used. Use of this structure with π-conjugated organic molecules results in a hysteresis loop with current-voltage measurements that are useful for an electronic memory device. The memory is non-volatile for more than 3 days, non-destructive for more than 1,000 reading operations and capable of more than 1,000 write-erase cycles before device breakdown. Devices without π-conjugated molecules (Si—H surface only) or with long-chain alkyl-bearing molecules produced no hysteresis, indicating that the observed memory effect is molecularly relevant.

Abstract:
The present invention is directed toward methods of attaching or grafting carbon nanotubes (CNTs) to silicon surfaces. In some embodiments, such attaching or grafting occurs via functional groups on either or both of the CNTs and silicon surface. In some embodiments, the methods of the present invention include: (1) reacting a silicon surface with a functionalizing agent (such as oligo(phenylene ethynylene)) to form a functionalized silicon surface; (2) dispersing a quantity of CNTs in a solvent to form dispersed CNTs; and (3) reacting the functionalized silicon surface with the dispersed CNTs. The present invention is also directed to the novel compositions produced by such methods.

International Classification:
G01N 25/20 G01N 33/00
US Classification:
436147, 422 83
Abstract:
An apparatus for characterizing parameters for the cracking, in-situ combustion, and upgrading of hydrocarbons includes a reactor defining a chamber, a temperature probe operably associated with the reactor, and a gas inlet in fluid communication with the chamber. The apparatus further comprises a gas outlet in fluid communication with the chamber and an electromagnetic radiation attenuating material configured to heat the reactor when the electromagnetic radiation attenuating material is irradiated by electromagnetic radiation.

Abstract:
Methods for analyzing a chart using an electronic computing device are presented, the methods including: causing the electronic computing device to receive a chart image corresponding with the chart, the chart image having recorded chart data; analyzing the recorded chart data, where the analyzing returns at least measurement values corresponding with the recorded chart data; and returning volumetric results of the processing to a user. In some embodiments, the recorded chart data corresponds with data selected from the group consisting of: temperature data, differential pressure data, and static pressure data. In some embodiments, the chart corresponds with a chart integration device or a chart recorder. In some embodiments, methods further include: capturing the chart image with a mobile image capture device.
Pressure Equalized Packaging For Electronic Sensors
The present disclosure introduces pressure-equalized packaging for electronic sensors utilized in conjunction with downhole tools and/or other extreme environments. Such sensors may be operable to detect, sense, and/or measure a parameter, such as may be associated with the downhole tool, or pressurized fluid in which the downhole tool is at least partially submerged, or a subterranean formation adjacent the downhole tool. A housing couples the sensor to a component of the downhole tool. The housing includes an equalizer operable to substantially equalize a first pressure internal to the housing with a second pressure external to the housing.
