20110200787 | Suspended Thin Film Structures - Disclosed is a method of preparing a support structure suitable for use, e.g., in microscopic studies, comprising a free standing atomically thin film (e.g. graphene) suspended across an opening in the support structure. The method in one aspect comprises the steps of preparing a thin film which is an atomically thin film (e.g., graphene) on a surface of a solid substrate to form a graphene-layered substrate; attaching the graphene layer to a hole-containing support mesh; removing the solid support, thereby transferring the graphene layer from the substrate to the carbonaceous hole-containing layer on the support mesh; and then removing contaminants to obtain said structure. In another aspect, the present method does not involve a transfer, but comprises a lithography and etching process in which the atomically thin layer is applied to a support which is marked with a lithographic pattern and selectively etched, leaving the free standing film. | 08-18-2011 |
20110272598 | SURFACE TENSION MEDIATED CONVERSION OF LIGHT TO WORK - Disclosed are a method and apparatus for converting light energy to mechanical energy by modification of surface tension on a supporting fluid. The apparatus comprises an object which may be formed as a composite object comprising a support matrix and a highly light absorptive material. The support matrix may comprise a silicon polymer. The highly light absorptive material may comprise vertically aligned carbon nanotubes (VANTs) embedded in the support matrix. The composite object is supported on a fluid. By exposing the highly light absorptive material to light, heat is generated, which changes the surface tension of the composite object, causing it to move physically within the fluid. | 11-10-2011 |

A cross-sectional dimension of the flexible conductor may be less than about 100 nanometers. The counter electrode may be disposed proximate the first end of the flexible conductor and spaced a first distance from the first end of the flexible conductor. The pumping electrode may be disposed proximate a length of the flexible conductor and spaced a second distance from the flexible conductor. | 09-18-2014 |

20090309676 | Tunable Multiwalled Nanotube Resonator - A tunable nanoscale resonator has potential applications in precise mass, force, position, and frequency measurement. One embodiment of this device consists of a specially prepared multiwalled carbon nanotube (MWNT) suspended between a metal electrode and a mobile, piezoelectrically controlled contact. By harnessing a unique telescoping ability of MWNTs, one may controllably slide an inner nanotube core from its outer nanotube casing, effectively changing its length and thereby changing the tuning of its resonance frequency. Resonant energy transfer may be used with a nanoresonator to detect molecules at a specific target oscillation frequency, without the use of a chemical label, to provide label-free chemical species detection. | 12-17-2009 |
20100239488 | Controlled Placement and Orientation of Nanostructures - A method for controlled deposition and orientation of molecular sized nanoelectromechanical systems (NEMS) on substrates is disclosed. The method comprised: forming a thin layer of polymer coating on a substrate; exposing a selected portion of the thin layer of polymer to alter a selected portion of the thin layer of polymer; forming a suspension of nanostructures in a solvent, wherein the solvent suspends the nanostructures and activates the nanostructures in the solvent for deposition; and flowing a suspension of nanostructures across the layer of polymer in a flow direction; thereby: depositing a nanostructure in the suspension of nanostructures only to the selected portion of the thin layer of polymer coating on the substrate to form a deposited nanostructure oriented in the flow direction. By selectively employing portions of the method above, complex NEMS may be built of simpler NEMSs components. | 09-23-2010 |

20080243537 | METHOD AND APPARATUS FOR THE SCHEDULED PRODUCTION OF PLANT EXTRACTS - A method for the just-in-time delivery of harvested plant material and plant compounds grown in a genetically-isolated growth environment is provided. The desired crop is grown in an underground growth chamber according to a predetermined growing model in which all growing conditions are controlled. Component yield and completion time can be accurately forecast such that the harvest time of the plant material, or the completion of upstream plant extract recovery, can be accurately forecast. The use of an underground growth chamber allows for complete control over environmental factors in growth of the plant material, and also allows for the best possible protection of the growing environment against any contamination of genetic material from outside of the chamber, as well as protection of the outdoor environment against any contamination of genetic material from inside of the chamber. The method will be particularly useful in the production of plant-made pharmaceuticals and nutraceutical. | 10-02-2008 |
