Power Electronics & Battery Technology - August 2019
This compendium of recent articles from the editors of Tech Briefs and Aerospace & Defense Technology looks at the latest advances in power electronics and energy storage.Blog: Energy
Our readers ask: How do you know that you have the right anode? How can you inspect the electrolyte or electrode material?
Blog: Electronics & Computers
Many of the technologies we use today – space blankets, hearing aids, food packaging – began on the Apollo 11 mission.
Briefs: Photonics/Optics
Experimental photonic switches developed at UC Berkeley have shown promise toward the goal of fully optical, high-capacity switching for...
Articles: Photonics/Optics
The critical angle lens reflector has commercial applications that supersede ordinary mirrored reflectors. The physics of the critical angle lens reflector are based on the optics...
Briefs: RF & Microwave Electronics
There's an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can't see. But infrared cameras can pick up this light emitted as...
Briefs: Energy
Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 °C and emanates from things like computers, cars, or...
Briefs: Electronics & Computers
Techniques to prevent frost and ice formation on surfaces rely heavily on heating or on liquid chemicals that need to be repeatedly reapplied because they easily wash away. Even advanced...
Briefs: Aerospace
Shear Assisted Processing and Extrusion (ShAPE™) allows creation of wire, bar, and tubular extrusions that show significant improvement in material properties; for example, magnesium extrusions have...
Briefs: Electronics & Computers
By capping liquids with graphene (an ultrathin sheet of pure carbon), researchers can easily image and analyze liquid interfaces and the surface of nanometer-scale objects...
Briefs: Materials
In the polymer composites industry, cure cycles are typically developed from trial-and-error or a more effective processing science approach to reduce the...

3D Printing of Flexible Circuits
A process was developed for 3D printing that can be used to produce transparent and mechanically flexible electronic circuits. The electronics consist of a mesh of silver nanowires that can be printed in suspension and embedded in various flexible and transparent plastics (polymers). This technology can enable new...
Briefs: Data Acquisition
Innovators at NASA’s Glenn Research Center have developed a new means of avoiding and mitigating icing events for aircraft flying above 14,000 feet, dramatically improving aviation safety...
Briefs: Electronics & Computers
Researchers have created highly stretchable supercapacitors for powering wearable electronics that consist of crumpled carbon nanotube (CNT) forests. The supercapacitors demonstrated solid performance and...
Briefs: Electronics & Computers
Researchers have developed a hybrid transformer that has the benefit of a full planar transformer design but uses a wire-wound secondary winding to keep the parasitic winding capacitances lower. Alone, planar transformers...
Briefs: Energy
A system was developed that can remove radioactive cesium contamination from porous structures such as brick and concrete that are hard to clean, as well as contamination from metal...
Briefs: Electronics & Computers
Whereas hydrogen fuel cells (e.g., proton exchange membrane (PEM) and other fuel cells) generate electricity from the chemical reaction between pure hydrogen and oxygen, direct carbon fuel cells (DCFCs)...

Advancements in zero-emission fuel cells could make the technology cheap enough to replace traditional gasoline engines in vehicles, according to researchers at the...
Briefs: Lighting
Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential of...
Briefs: Energy
Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the unusual behavior of some liquids...
