Additive manufacturing is steadily advancing towards fulfilling its promise of customized and on-demand production of functional parts. However, performance of as-manufactured parts can differ significantly from the as-designed parts because the as-manufactured geometry differs from the as-designed geometry and the asmanufactured material properties are not known. Attempts to predict performance o ...

Our biosensor is made of silicon nanowire arrays functionalized with antibodies to measure the concentration of specific proteins. In this grant we will take a sensor that has been demonstrated for use in measuring a set of generic host cell proteins and we will apply the sensor to measure a set of proteins for a specific cell line. In doing so, we will demonstrate the utility of our sensor to be ...

Our innovation is a low cost, sensitive, quantitative biosensor that can detect many biomarkers on the same chip. Our sensor consists of vertically aligned silicon nanowires. The silicon nanowires’ high surface area to volume ratio makes them sensitive to the environment around them and can thus lead to high sensitivity detection. Each of the nanowires can be functionalized to be sensitive to ei ...

TECHNICAL ABSTRACT: Buoyancy driven oceanographic gliders, although reasonably cost effective, have challenges operating in the zones due to high gradients in water density. Under this topic, Riptide will provide a cost-effective autonomous undersea vehicle (AUV) design leveraged from Riptide's family of man-portable AUVs that can more effectively map the hypoxic areas. The stated goals of this to ...

TECHNICAL ABSTRACT: Bottom Feeder will be a highly maneuverable Autonomous Underwater Vehicle (AUV), with a tethered operations option and modular sensor bay, to support benthic optical surveys, coral reef mapping and health assessment, and be expandable for future survey operations. It will integrate a low drag hullform, a minimum of four degrees of independent motion control, a highly efficient ...

TECHNICAL ABSTRACT: We propose to develop and commercialize the next generation of low cost, low power, ruggedized, and accurate phytoplankton single cell and whole colony counting, characterization and classification system called HABStats. We will accomplish this using the following three unique and innovative approaches: 1) High-throughput color, Light Field Imaging Flow Cytometry to acquire mo ...

TECHNICAL ABSTRACT: Triton Systems, Inc. proposes development of the Open-Source Oceanographic Asset Recovery Beacon (OpenORB) that will allow the deployment of coastal instrumentation moorings with affordable protection against loss. This open-source kit would significantly reduce the purchase price of a commercial location beacon by allowing the end-user to assemble a customized system with mini ...

TECHNICAL ABSTRACT: Poor air quality represents a major public health risk, contributing to an estimated one of every eight deaths worldwide. Low-cost air quality sensors have developed rapidly over the last few years and offer the opportunity to make air quality monitoring inexpensive and widespread. However, low-cost sensors are currently unable to deliver accurate, reliable data due to a lack o ...

TECHNICAL ABSTRACT: Commercial marine aquaculture operators face many operational hazards including disease, predators, husbandry operations, and environmental changes. Most of theses risks are only identified with constant surveillance and physical presence at a farm site. However, human observation of risk factors is expensive, slow, and sometimes ineffective. Sensors are available to monitor in ...

TECHNICAL ABSTRACT: Recent advances in gas chromatographic (GC) and mass spectrometric (MS) techniques for atmospheric measurements have led to highly complex data sets that have overwhelmed the capabilities of current data analysis software. We propose a new method for the automated reduction of chromatographic data using peak-fitting algorithms. By relying upon constrained peak-fit parameterizat ...
