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 ...

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 ...

CU Aerospace (CUA) and the University of Michigan (UM) propose the development of the Cycle Automated Mass Flow (CAMFlow) system for reliable and well-regulated flow control. CAMFlow uses an innovative control scheme that enables stable operation using only Boolean valve states, even for the low flow rates necessary for sub-kilowatt Hall effect thrusters. This methodology removes system complexity ...

The team of CU Aerospace (CUA) and the University of Illinois at Urbana-Champaign (UIUC) proposenbsp;risk reduction design and analyses of a modular spacecraft addition based on our teamrsquo;s CubeSail technology for accelerated spacecraft deorbiting.nbsp;nbsp;This technology represents a high-payoff technology using primarily atmospheric drag, but with the additional option for solar sail deorbi ...

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 ...

CU Aerospace (CUA) proposes the scaling of an alternative very low-toxicity monopropellant thruster to a 0.5 N class engine.nbsp;nbsp;nbsp;CMP-8 (CUA Mono-Propellant 8) is a non-detonable yet energetic COTS formulation that possesses many system-level advantages including lower cost (COTS propellant and non-refractory thruster construction), lower thermal load (lt;1000deg;C flame temp), low viscos ...

Hyperspectral datasets are massive. This size makes them difficult to acquire, store, transmit, analyze and use. Hyperspectral imagers (HSI) are also costly and complex, taking significant time or portions of a focal plane to acquire each spectral band. In addition, orbital HSIs are susceptible to radiation damage and inaccessible for repairs, making any damage long-lasting.nbsp;In this effort, we ...

This Phase I proposal is submitted to verify the materials and process engineering of the space environment stable, multifunctional Plasma Sprayable conductive thermal control material system (TCMS) that can be applied to space hardware and can enables the hardware to carry higher leakage current through co doping process engineering for the high electrical conductivity. An innovative space enviro ...

In extremenbsp;temperatures withnbsp;variable atmospheresnbsp;in space exploration, traditional oil lubricants and greases are infeasible. To develop and verify the correct bearing materials/lubricants for these environments, we will use a special instrument for tribological study at extreme temperate conditions with a controlled gas atmosphere. We propose preliminary testing of one tribo-pair of ...

MicroLink Devices proposes to develop triple-junction (3J) epitaxial lift-off (ELO) solar cells containing Bifacial Back Metal Mirror (BBMM) technology to allow for reduced mass through device structure thinning as well as cooler and more efficient operation by selectively rejecting excess broadband infrared (IR) radiation. These BBMM 3J solar cells will achieve 33% 1-Sun AM0 beginning-of-life (BO ...
