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 ...

Assessment of wild land fire smoke exposure is a genuine concern to fire managers, public health officials, air quality regulators, and the public. Exposure to vegetation fire smoke products poses acute and chronic health hazards to first line responders, firefighters, and to communities located downwind of their source. Current instrumentation capable of providing reliable air quality data is exp ...

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 ...

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 portable life support system for the exploration space suit (xPLSS) must control CO2 and humidity levels inside the space suit pressure garment. The preferred approach is to use a pressure swing adsorption process based on Amine Swingbed technology. One of the key technical challenges for xPLSS operation on the Martian surface is the need to vent CO2 and water vapor from the swingbeds to an am ...

Future astrophysics missions require efficient, low-temperature cryocoolers to cool advanced instruments or serve as the upper-stage cooler for sub-Kelvin refrigerators. Potential astrophysics missions include Lynx, the Origin Space Telescope, and the Superconducting Gravity Gradiometer. Cooling loads for these missions are up to 300 mW at temperatures of 4 to 10 K, with additional loads at higher ...

As the power levels and sizes of small satellites grow, new applications open up, along with new challenges for thermal control. Greater amounts of heat must be transported across longer distances, making it more difficult to control component temperatures using simple, passive systems. We propose to develop an innovative thermal storage technology for small satellite thermal control systems. Our ...

The proposed project utilizes the unique capabilities of the Materials International Space Station Experiment-Flight Facility (MISSE-FF) platform to perform low-Earth orbit (LEO) materials validation testing to advance the Technology Readiness Level (TRL) of advanced spacesuit hard upper torso (HUT) composite materials developed under a prior NASA SBIR Phase I/current Phase II contract.nbsp; The d ...

Refueling spacecraft in space offers tremendous benefits for increased spacecraft payload capacity and reduced launch cost. However, in a microgravity environment, acquiring vapor-free cryogenic liquid propellants from supply tanks and then transferring them to receiving tanks is very challenging. To address this challenge, Creare developed a robust, lightweight hybrid Liquid Acquisition Device (L ...
