Diode-laser arrays operating in the visible region of the spectrum offer advantages for illuminator applications, particularly for night and water penetration capability. Recent developments in diode-laser materials allow operation throughout the visiblespectrum. At this time, red diode-laser technology is more mature than the existing blue-green or violet diode-laser technology. The novel aspe ...

DESCRIPTION (Unedited Applicant's Abstract):When people with diabetes reach end-stage renal disease they must undergo either dialysis or transplantation. About 200,000 Americans need artificial kidney machines to stay alive. These machines rely on sterile dialysis membranes to remove toxic materials from the bloodstream. More than 30 different polymers or polymer blen ...

DESCRIPTION (Verbatim from the Applicant's Abstract): This Phase I SBIR application seeks support to develop and evaluate a naturally-occurring extracellular matrix (ECM) bioscaffold material for tissue engineering applications; specifically, the repair and/or restoration of congenital defects in which lost or missing tissue is the limiting factor for s ...

SINCE THEIR DISCOVERY NEUTRONS HAVE REMAINED ONE OF THE MOST DIFFICULT FORMS OF RADIATION TO DETECT. THE MOST EFFECTIVE NEUTRON DETECTORS IN CURRENT USE ARE GAS FILLED DETECTORS EMPLOYING EITHER 3HE OR BF3 AS THE DETECTION MEDIUM. UNFORTUNATELY, GAS FILLED DETECTORS SUFFER FROM A NUMBER OF DEFICIENCIES INCLUDING LARGE SIZE (GASES HAVE LOW VOLUMETRIC EFFICIENCY FOR STOPPING NEUTRONS), MECHANICAL FR ...

NOVEL TECHNIQUES ARE PROPOSED FOR CONSTRUCTING W-BAND TRANSMITTER SOURCES FOR USE IN HYPERVELOCITY MODELS OF PROJECTILES. THE PROPOSED STUDY INVOLVES THE MECHANICAL AND ELECTRICAL DESIGN OF PLANAR, INTEGRATED GUNN DIODE OSCILLATORS WHICH CAN OPERATE DURING ACCELERATION GREATER THAN 100,000 G. THE SALIENT FEATURES OF THESE SOURCES ARE: PRINTED-CIRCUIT CONSTRUCTION; INDIUM PHOSPHIDE FUNDAMENTAL-MODE ...

DESCRIPTION: (provided by applicant) The goal of this program is to develop accelerator mass spectrometry (AMS) as an analytical tool for cancer research, specifically for tracing the interactions of carcinogens and cancer chemotherapeutic drugs with their biomolecular targets. AMS is a highly selective means for d ...

Use of a new noninvasive test for the accurate early detection of preeclampsia is proposed as a tool to screen women during early stages of pregnancy. Preeclampsia affects 10% of the 4 million pregnancies in the U.S. each year and is the leading cause of maternal and neonatal medical complications and death. There is currently no means of detecting preeclampsia prior to onset of clinical symptoms ...

This project will enhance the competitiveness of the U.S. aquaculture industry by providing a cost- effective means of increasing the rate of genetic improvement of hybrid striped bass. We will compare the reproductive, hatchery and grow-out performance of selectively bred hybrid striped bass and backcross hybrid striped bass of common genetic origin. We will also benchmark our findings via compar ...

Researchers at the NIST have demonstrated a programmable Voltage Standard (VS) chip based on SNS (superconductor-normal-superconductor) tunnel junction technology. Excellent programmable voltage standards were demonstrated using this SNS technology in a liquid helium-based system. At HYPRES, we have developed and commercialized a Closed Cycle Refrigerator (CCR)-based DC voltage standard system usi ...
