Perfluoroalkyl substances (PFASs) have been identified as a serious health contaminant in water at levels between 12 and 516 parts per trillion by the Agency for Toxic Substances & Disease Registry. In 2016, the EPA set a lifetime health advisory of 70 parts per trillion for two PFASs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). These compounds come from a variety of so ...

Per- and polyflouralkyl substances, otherwise known as PFAS, are a large group of chemicals including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). These chemicals have a large variety of uses globally. Remediation of PFAS has gained importance due to their environmental persistence and toxicity. Water treatment methods must combine multiple strategies to be effective, as PF ...

The Construction and Demolition Debris Support Vector Machine Optical Recycling Technology (CDDSORT) is our proposed system that detects hazardous, problematic, and recyclable components in the 150+ million tons of construction and demolition (C&D) debris discarded annually at US landfills and recycling facilities. Our system and technology leverages a combination of emerging computer vision techn ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logisticalsystem requires natural gas gathering lines, processing facilities,product storage tanks and Jots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermitte ...

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 ...

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 ...

The Interdisciplinary Consulting Corporation (IC2) proposes to continue development of dual-axis shear stress sensors that are applicable in ground test facilities covering a large range of flow speeds in response to NASA SBIR 2018 Phase I solicitation subtopic A1.08. The proposed sensing system addresses a critically unmet measurement need in NASArsquo;s technology portfolio, specifically the abi ...

The purpose of this Phase II proposal is development of a completely operational 4.3 GHz passive sensor system that will be compliant in the newnbsp;Wireless Avionics Intra-Communications (WAIC) band.nbsp;nbsp;This band will be useful to both space and aerospace, and the center frequency significantly advances SAW sensor device capabilities to very high frequencies.nbsp;nbsp;The focus of the effor ...

A new UV imaging polarimeter design was demonstrated by Optical Coating Solutions, Inc. (OCS) as a proof-of-concept breadboard in a 2016 Phase I effort (NASA Contract NNX16CA44P). A version of that generic design is proposed for atmospheric studies in a follow-on effort.nbsp;The new polarimeter design can operate to wavelengths as short as 260nm and does not employ electronic or mechanical modulat ...

The Interdisciplinary Consulting Corporation (IC2) proposes the development of a low-profile instrumentation-grade pressure sensor for in-flight aerodynamics measurements using microelectromechanical systems (MEMS) based piezoelectric sensing with backside contacts and advanced packaging technology.nbsp; The goal of this research is to develop a pressure sensor that meets the demanding in-flight p ...
