Sepax Technologies, Inc. has identified a new type of anoin-exchange resin which separates single-wall carbon nanotubes (SWCNTs) with >80% recovery yield and resolves in a single pass the chiral tubes of (6,5) well from commercial SWCNT starting materials by Chromatography. Improvement and scale up of the targeted resin production will facilitate the separation of chiral nanotubes for the academic ...

This Phase 1 SBIR project aims to develop a frequency stabilized laser diode system suitable for application in optical metrology and in displacement measurement. The compact design of the semiconductor laser lends itself to many applications where a coherent light source is required, but space is at a premium. Some fields, such as precision optical metrology require a coherent light source whose ...

ABSTRACT: To address the need for covert, transparent optical taggants, which can upconvert and downconvert greater than 100 nm when stimulated by either 830 nm or 1064 nm laser light, a series of wide bandgap doped metal oxide nanoparticles will be developed and demonstrated. In Phase I, lanthanide-doped core-shell nanocrystals will be fabricated that are sufficiently small (e.g.

Currently nuclear-based gauges are the most widely used equipment in the construction industry to measure moisture and density of pavement materials. Such measurements are very accurate, rapid, and non-destructive. Attempts to replace these nuclear methods by non-nuclear methods have shown strong limitations. For this project, we propose to integrate nuclear and seismic technologies to measure t ...

We plan to implement a planar Molecularly Controlled Semiconductor Resistor (MOCSER) gas sensor on both InAs and InN platforms for the ppt-ppm detection of NOx and H2O. Kyma Technologies and Duke University will leverage Duke"s leading MOCSER based NOx sensor technology which uses surface functionalization of InAs with hemin (chloroprotoporphyrin IX iron(III)) to create a strong affinity for NOx. ...

Aluminum Gallium Nitride (AlGaN) has broad dual use applications for power transistors, high frequency transistors, high power Schottky barrier diodes, and solar-blind detectors, as well as ultra-violet laser diodes and ultra-violet light emitting diodes. This unique material system spans the capabilities that lie between Gallium Nitride (GaN) and Aluminum Nitride (AlN), enabling custom tailored p ...

Next-generation high-performance computers (HPCs) are built as massively parallel systems where the parallelism exists at many levels. These systems are a collection of nodes all working together. Each node generally contains more than one processor and each processor contains multiple cores. Managing and efficiently utilizing the different parallelism in such a system is a complex task. Furth ...

The overall objective of this program is to improve the producibility of HVPE GaN through the use of in-situ monitoring during the growth process. Various in-situ monitoring devices will be used: a UV absorption technique to monitor the GaCl concentration above the growing GaN wafer; a commercial BandiT system capable of measuring optical emission from the growing wafer in order to measure the su ...

ABSTRACT: MO-SCI Corporation and Missouri University of Science and Technology have developed and evaluated fusion welding technology applicable to ultra-high temperature ceramic (UHTC) composite joining during a Phase I ceramic joining program. This Phase II program will improve arc and reactive plasma arc welding techniques and consumables to improve joint quality. Work in the Phase I resulted ...

ABSTRACT: High-performance computing (HPC) programmers and domain experts, such as those in the Air Force's research divisions, develop solvers for a wide variety of application areas such as modeling next generation aircraft and weapons designs and advanced image processing analysis. When developing software for HPC systems, the programmer should not spend the majority of their time optimiz ...
