Completely biodegradable filtration system for waste metal recovery from aqueous solution

End-of-life electronics waste's hazardous chemical components have been a significant threat to rapid socioeconomic growth and technological innovation. Conventional extraction techniques rely on energy-intensive processes and are ineffective when applied to recycling e-waste or small amounts of metals.

Advanced Supercritical Water Oxidation Reactor

The SCWO-FPV Reactor operates at temperatures and pressures above the thermodynamic critical point of water, allowing organic material to become highly soluble, effectively eliminating all carbonaceous waste introduced into the reactor by the reactor's soluble solid material. Although the SCWO-FPV Reactor is being considered for space exploration missions, it does have a lot of terrestrial uses, especially for water reclamation, water purification, and waste reduction in liquid waste streams.

Single Crystal Semiconductor Silicon-Germanium (SiGe)

SiGe offers increased processing capability and reduced weight for a unit of the same size with 4x faster carrier mobility and less energy loss than single crystal silicone, reduced size, and reduced weight. SiGe has introduced new design features that increase its productivity by 36% and the operational life to 82 years in solar cell applications, as shown by the graph.

Habitat Water Wall for Water, Solids, and Atmosphere Recycle and Reuse

The membrane water wall system includes a membrane-based water, solids, and air treatment function that is embedded into the walls of inflatable or rigid habitat walls. It provides novel and potentially game-changing mass reuse and structural advantages over existing mechanical life support hardware. This approach may dramatically reduce the cost of human space flight by upgrading the mass, stability, and number of conventional life support hardware.

Activated Metal Treatment System (AMTS) for Paints

The Activated Metal Treatment System for treating polychlorinated biphenyls in paints is seeking partners interested in the commercialization of the Activated Metal Treatment System for treating polychlorinated biphenyls in paints. Surface cleaning methods are often able to remove PCB-containing paint from surfaces; however, these methods tend to produce a new waste stream that must be addressed according to Toxic Substances Control Act rule.

Calibration System for Automated Fiber Placement

Innovators at NASA's Langley Research Center's Langley Research Center have developed a Calibration System for Automated Fiber Placement machines. AFP uses a robotic arm to cut stripes of carbon fiber prepreg to build up a composite part layer by layer, rather than making aerospace parts and wind turbine blades. New In-situ inspection systems are on the rise, but no way exists to produce accurate "defect specifications" that enable active system calibration. The next generation of AFP in situ inspection techniques will be enabled by NASA's new calibration system.

Thermal Management for Aircraft Propulsion Systems

Conventional aircraft propulsion systems struggle to maintain high-powered electric motors and electronics cool without resorting to additional mass and complexity that negate the benefits of electric propulsion in aircraft. The waste heat creates a high-intensity acoustic wave, which is generated by the temperature difference between the hot and cold heat exchangers. Although cooling the aircraft's propulsion system without increased mass and complexity, Glenn's system can deliver a high-efficiency electric power to aircraft components while also cooling the aircraft's propulsion system without adding mass and complexity.

Optical Tunable-Based Transmitter for Multiple High-Frequency Bands

As the demand for more radio frequency carrier bands in space communication systems rises, so does the need for a cost-effective compact optical transmitter capable of efficiently transmitting multiple RF bands. Traditionally, when a satellite broadcasts to another satellite or a ground station, a separate terminal with a corresponding antenna is required for each radio frequency band. Now, however, NASA's Glenn Research Center researchers have successfully developed a device that converts and broadcasts multiple microwave bands with various modulation modes and bandwidths.

Silicon Oxide Coated Aluminized Polyimide Film Radiator Coating

CubeSat, a miniature satellite, has deployable solar arrays and/or body mounted solar cells that provide enough electrical power to satisfy mission power requirements. The waste heat must be radiated from exterior to deep space in order to maintain component temperatures within allowable flight limits. Additionally, MLI blankets not only increase the volume of the CubeSat, but also raise the possibility of entanglement during solar array deployment. Without these drawbacks, the SiOx Coated Aluminized Polyimide Film Radiator Coating regulates the temperature for CubeSats.

Pre-Treatment Solution for Water Recovery

The Pre-Treatment Solution for Water Recovery was created by NASA Johnson Space Center innovators to increase the amount of potable water recovered from the International Space Station's urine processing system. Three primary steps in turning sewage, urine, or seawater into potable water include: 1 pre-treatment, 2 distillation, or membrane filtration, and 3 transport and storage of potable water and brine. In addition, the solution contains a biocide to inhibit bacteria proliferation, thus increasing storage time and amount of water recovered.
