Single chirality of single-walled carbon nanotubes (SWCNTs) is critical for their superb mechanical, thermal, optical and electronic properties. All known methods for producing nanotubes give mixtures of tubes with different chiralities. Physical separation of SWCNT by chirality is thus an enabling step for many potential applications and fundamental studies. The existing anion exchange resins are ...

Nanometrology International, Inc. (NMI) proposes to demonstrate the feasibility of 3-dimensional (3D) characterization of nanoscale objects using scanning probe microscopy (SPM) with a measurement uncertainty of less than 0.7 nm. To accomplish this task, we propose a novel method of 3D tip characterization and use of an innovative surface reconstruction algorithm recently introduced by NIST and th ...

This Phase 2 project targets the completion of the development of an improved system for the broadcasting of the WWVB signal, as a direct continuation of the Phase 1 project, which successfully validated the proposed approach through a feasibility study and analyses. Objectives of this project include the design of the new modulation scheme and protocol, the development of a new time-code generato ...

The applicant will develop a wave energy harvesting system for NOAA buoys. It will ve entirely self-contained (no protruding elements), modular, scalable, and easily deployed. The system employs a unique, inertial mechanism that responds to acceleration forces created by waves. This mechanism will be combined with (1) a proprietary generator that is sensitive to very low levels of torque and ha ...

The air-launched expendable Small Unmanned Aerial System (SUAS) under development by the Air Force can expand mission capabilities by extending the range of on-board sensors, tracking multiple targets, increasing target acquisition accuracy, and providing direct support for ground teams. Current state-of-the-art battery technology provides Group 1 SUAS with approximately 25-60 minutes of operati ...

The Directed Energy Tactical Mission Application Code (DETMAC) is a mission planning simulation tool to model directed-energy weapon capabilities, target vulnerabilities, and environmental constraints. It will be used by mission planners to visualize an entire mission timeline and prompt development of optimal tactics, techniques and procedures for successful employment of new weapon capabilities ...

A low-cost superconducting transition edge sensor (TES) microcalorimeter spectrometer is described for high energy and high spatial resolution X-ray energy dispersive spectroscopy and microanalysis. The proposed microcalorimeter instrument offers an energy resolution that is comparable to and potentially even better than wavelength dispersive spectrometers, thereby enabling the resolution of inter ...

his proposal focuses on developing Distributed Automatic Reconfigurable Trasponder (DART) system that is capable of achieving distributed multi-nodal voice/data communication for firefighters. Specifically, Williams-Pyro, Inc. proposes to develop an enhanced prototype of distributed Automated Reconfigurable Intelligent Radios, which consists of a series of distributed nodes that will relay voice t ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...

MOTOR OPERATED GATE VALVE OPERABILITY PROBLEMS AND FAILURES AT NUCLEAR POWER PLANTS ARE A MAJOR SAFETY CONCERN AS STATEDIN NRC IE BULLETIN 85-03 AND GENERIC LETTER 89-10. THIS PROPOSAL IS AIMED AT IMPROVING GATE VALVE PERFORMANCE BY (1) DEVELOPING COMPREHENSIVE PERFORMANCE PREDICTION MODELS FOR USE OVER A RANGE OF OPERATING CONDITIONS, (2) DEFINING LIMITS, BASED ON SPECIFIC DESIGNS, BEYOND WHICH E ...
