20100237325 | Highly resolved, low noise, room-temperature coulomb-staircase and blockade up to 2.2V in isolated 50 micron long one dimensional necklace of 10 NM AU particles - Coulomb blockade in metal nanoparticles isolated by a tunneling barrier is considered to be a potential solution to low power, robust, high-speed electronic switching device operating at single-electron transport. However, the switching voltage equal to the threshold voltage to overcome coulomb blockade for these devices is typically in the 10 mV range and/or operating at currents well below 1 nA, which inhibits their application as a practical device. Theoretically, a one dimensional nanoparticle necklace is predicted to be an ideal structure to achieve higher switching voltages. The present invention provides a single-electron device composed of a necklace of about 5000 nanoparticles. The linear necklace is self-assembled by interfacial phenomena along a triple-phase line of fiber, a substrate and electrolyte containing nanoparticles. The I-V measurements on the system show both coulomb blockade and staircase, with high currents and high threshold voltage of 1-3 V. The present invention also provides methods for constructing such a device. | 09-23-2010 |

20090070064 | VERTICAL TRACK MODULUS TRENDING - Systems and methods for determining a trend in vertical track modulus are disclosed in accordance with embodiments of the present invention. Vertical deflection data is collected along a particular section of railroad track. A first set of vertical track modulus is determined, based in part, on the collected vertical deflection data. At a second time, vertical deflection data is again collected along the particular section of railroad track to be used in determining a second set of vertical track modulus. At least the first and second sets of vertical track modulus are analyzed to determine a mathematical algorithm that facilitates developing a trend in the vertical track modulus of the railroad track. | 03-12-2009 |
