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 ...

Non-destructive evaluation (NDE) using acoustic vibrations is a widely used method to assess unique structures and composite materials. Non-contact forms of ultrasonic NDE, such as laser-induced ultrasound, are particularly suited for in situ evaluation in extreme environments. Current limitations of this method include the inability to identify shadowed defects, probe double-walled vessels, and e ...

Bulk metallic glass (BMG) has gained popularity over the last two decades as alloys have been developed that can remain in a supercooled state at sufficient intervals to allow for processing in a similar manner to plastics. Their physical properties, including an unusual combination of hardness, strength, and elasticity, have made them ideal candidates for the production of strain wave gears. Both ...

This NASA STTR Phase I proposal is aimed at rapid prototyping of antennas beam-shaping with metamaterials and metasurfaces through additive manufacturing of a highly conductive filament - Electrifi. The proposal includes the use of the highly conductive 3D printing filament, which was developed by Dr. Shengrong Ye, the principal investigator at the SBC - Multi3D and is at least 100 times more cond ...

Nerve agents exert their toxic effect by binding to and inactivating enzyme acetylcholinesterase, a key enzymatic regulator of cholinergic neurotransmission. The binding becomes irreversible after a varying amount of time with nerve agents and this aging process limits the treatment window of oxime reactivators. To enhance the current antidote treatment of nerve agent autoinjectors, a pyridostigmi ...

Advanced Liquid Logic proposes to develop a very capable analyzer based on its digital microfluidic technology. Such an analyzer would be:  Capable of both simple and complex biological assays  Small, lightweight, power efficient, and easy to operate  Fully programmable and remotely reprogrammable Under NIH funding we have demonstrated clinical chemistry blood diagnostic testing on our ...

A clear need exists for the next generation of Ceramic Matrix Composites (CMC) for Thermal Protection Systems (TPS), propulsion hardware, and other high temperature applications. No "off-the-shelf" materials and/or processes capable of meeting NASA's goals are available, yet completely integrating a unique combination of commercially available or nearly commercially available technologies can m ...

The many different generations of integrated circuit (IC) technologies required for new space exploration systems demand designs operate at multiple and often incompatible voltages. Extended utilization of current and development of new space exploration systems require multiple voltage levels be successfully integrated to interface technologies. NASA's micro-satellites and space exploration mis ...

Manning Applied Technology proposes development of the MP-100 handheld FT-infrared photoacoustic chemical agent detector, following a highly successful Phase I effort. Chemical attacks and accidents can be mitigated partially by cost-effective sensors. High priority programs will benefit from a sensor compliant to Joint Warning & Reporting Network (JWARN) standards. The device is ideally suited to ...

In response to RFP S8.04 Spacecraft Propulsion, innovations in propulsion technologies are needed to increase the capabilities of the Science Mission Directorate (SMD) spacecraft. Towards this need, MicroPhase Coatings, Inc. (MPCI) proposes tank bladders compatible with advanced monopropellants. MPCI is well underway in development of polymer liners for lightweight propulsion tanks for containme ...
