This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...
Traditionally, electronics are cooled using a heat sink that transfers the heat generated by the electronic system into the air or a liquid coolant. For the heat sink to work, it has to...
Making electric cars lighter also involves reducing the weight of the motor. One way to do that is by constructing it from fiber-reinforced polymer materials. A new cooling concept...
Thin, durable heating patches were created using intense pulses of light to fuse tiny silver wires with polyester. Their heating performance is nearly 70 percent higher than similar patches. The inexpensive...
Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven...
HiETA develops metal additive manufacturing (AM) methods for the production of complex, lightweight structures for heat management...
A heat-rejecting film was developed that could be applied to a building’s windows to reflect up to 70 percent of the Sun’s incoming heat. The film remains highly transparent...
The demand for more functionality in smaller footprints is growing across the product spectrum. To address the more challenging thermal management requirements resulting from this trend, packaging engineers are beginning to turn to Pumped Two Phase (P2P) cooling solutions....
A team of researchers at the New York University Tandon School of Engineering and NYU Center for Neural Science has solved a longstanding puzzle of how to build ultra-sensitive, ultra-small, electrochemical...
To address the demand for a more accurate, reliable, customizable, and easy-to-use force measurement device, Interface Force Measurement Systems (Scottsdale, AZ)...
Small unmanned aircraft systems (UAS), also known as micro air vehicles, are promising tools for a variety of military and commercial applications. Some small UAS have flexible wings and are lightweight, making them back-packable and easy to deploy. Most UAS that are...
Heat shields are essentially used as the brakes to stop spacecraft from burning up and crashing on entry and reentry into a planet's atmosphere. Current spacecraft heat shield methods include...
One of the first things an electrical engineer will learn is that the number-one enemy of designing and manufacturing any electrical/electronic product is heat. It's the one...
NASA Marshall has developed a system for generating iodine vapor from solid iodine for use as a propellant in a Hall or ion thruster propulsion system. Xenon has generally been the preferred propellant for these spacecraft ion propulsion systems but more recently, iodine-based...
Fuel cells can deliver clean, reliable, and uninterrupted power nearly 100 percent of the time. Fuel cells offer the advantage of efficiency by converting chemical energy directly to electricity. They have no moving parts, thereby eliminating failures associated with pumps, blowers, heat exchangers, and other...
Most electronics only function within a certain temperature range but blending two organic materials together creates electronics that withstand extreme heat. The new plastic material could reliably conduct...
NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....
Mandal, along with Professors Yuan Yang and Nanfang Yu, built upon earlier work demonstrating that many simple plastics and polymers are excellent heat radiators that could be used for passive radiative daytime cooling (PRDC). Their challenge was to get these normally...
Existing optics mounts sandwich the optic axially between two metal components, which can lead to optical surface damage and misalignment when exposed to fluctuating temperatures. Thermal-compensating...
A stainless steel alloy — alloy 709 — has potential for elevated-temperature applications such as nuclear reactor structures. It is exceptionally strong and resistant to damage when exposed to...
Innovators at NASA's Glenn Research Center have expanded their growing portfolio of aerogels to include a new optically transparent polyimide aerogel. Aerogels — low-density, highly porous,...
