This NASA sponsored STTR project will investigate methods for close-out of large, liquid rocket engine, nickel or stainless steel nozzle, coolant channels utilizing robotic laser and pulsed-arc additive manufacturing (AM)methods. Structural jacket to coolant channel land area interface strength will be quantified and metallurgical characterization completed.Process optimizations will be conducted ...

Military respirator masks provide the Warfighter with life critical protection against chemical, biological, radiological, and nuclear (CBRN) threats. To ensure the safety, comfort, and effectiveness of the American Warfighter, it is essential that every Warfighter be assigned a respirator that is properly sized and fitted. However, current methods for sizing and fitting respirators depend on manu ...

In addition to military scenarios, many environmental inhalant hazards exist in the workplace, from industrial sites to medical facilities. Frequent training and practice are an essential component of effective protection, yet valid methods for assessing proper mask fit are usually not provided beyond the minimum requirements and there is a significant lack of mask fit training to ensure that prop ...

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 ...

Phase I has proven that the current setup achieves better than 8mm spatial resolution for 2.2MeV prompt gammas. However, 1mm spatial resolution presents a significant challenge for the current setup due in part to limited timing resolution and count rate. A new analog ASIC will be developed to replace the current analog ASIC that will have better timing resolution and deliver higher count rates. I ...

This project will develop a new scientific instrument optimized for the advanced characterization of near-infrared fluorescent nanoparticles that can exist as left- or right-handed structures (enantiomers). Single-walled carbon nanotubes (SWCNTs) are the leading current example of such nanomaterials. Applied NanoFluorescence, LLC (ANF) proposes a novel multi-mode chiroptical spectrometer that can ...

Technology currently used for terrestrial navigation is extremely limited in the challenging environments on icy moons and ocean worlds such as Europa. Autonomous platforms used to collect data from beneath these ice and ocean surfaces cannot depend on access to satellite or any other electromagnetic communication. Autonomous systems in these environments are required to perform highly-complex tas ...

The aim of the proposed program is to design metasurface structures to manipulate electromagnetic waves of extremelynbsp;different frequencies, from visible light to THz.

Metamaterial optics provide dramatic reductions in size and weight compared with traditional refractive optics. Nanohmics, Inc., and Andrea Alugrave;rsquo;s group at the City University of New York propose to develop ultrathin, light-weight, high-transmittance optics based on microfabricated gradient metagratings. A metagrating is an array of polarizable metamaterial particles with a period compar ...

Suppression of noise from aircraft is a vital NASA goal, especially important for the vision of Urban Air Mobility. Small urban aircraft may utilize Distributed Electric Propulsion along with advanced structural and electric motor/storage technologies to achieve the necessary flight capability. However, these aircraft utilize propellers or fans to achieve the necessary thrust, with attendant commu ...
