Simon Fraser University and Swiss researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be...

This invention applies to the field of sputtering, depositing SiGe thin films on sapphire substrates. It is a method of modifying the film...

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It...

Additive manufacturing, or 3D printing, is a rapidly growing field in which solid objects can be produced layer-by-layer. This...

Most 3D printers, including light-based techniques, build up 3D objects layer by layer. This leads to a “stair-step” effect along the edges. They also have difficulties creating flexible...

Anew material was developed that can extract the key ingredient in the most common form of plastic from a mixture of other chemicals while consuming far less energy than usual....

NASA’s Langley Research Center has developed a new way to reduce the high-temperature heating requirement of sapphire substrates in wafer production. The growth of...

Unwanted porosity is typical to many manufacturing processes — from traditional casting to additive manufacturing (3D printing) — and is difficult to avoid entirely....

Nearly all commercial products start as a CAD file — a 2D or 3D model with the product’s design specifications. One method that’s widely used to represent today’s 3D models is...

Existing techniques for creating nano-structures are limited in what they can accomplish. Etching patterns onto a surface with light can produce 2D nano-structures but doesn’t work for 3D structures....

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...

Researchers at the University of Houston have created an inexpensive system that can detect lead in tap water at levels commonly accepted as dangerous, using a lens made with an...

Fast-response, stiffness-tunable (FRST) soft actuators — or movable machine elements — were developed that could be used in soft robots.

Industrial machinery, agricultural equipment, transportation vessels, and home applications depend on lubricants; however, they leave a heavy environmental footprint. Common lubricants, oils,...

NASA’s Langley Research Center has developed a method in which a metal matrix composite (MMC) material is incorporated into a metallic structure during a one-step...

Along with intensity and color, polarization is a property of light that can provide useful information for scene analysis; however, the human eye and most cameras cannot detect...

From cellphones to satellites, industry spends millions on traditional gold alloy electrical contact coatings. While gold and other metal alloys have been an industry standard to protect metal components...

The mechanical properties of sheet metal materials are directional. Their deformation behavior and their strength differ significantly depending on the viewing direction; for example, in the direction of rolling, or...

Titanium is as strong as steel but about twice as light. These properties depend on the way a metal’s atoms are stacked but random defects that arise in the...

Optical range measurements, already used in manufacturing and other fields, may help overcome practical challenges posed by structural fires, which are too hot to measure with conventional...

Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors....

Wearable biosensors for health monitoring lack a lightweight, long-lasting power supply. A new method was developed for making a charge-storing system that is easily integrated into...

To keep up with Moore's Law — an observation made in the 1960s that the number of transistors on an integrated circuit doubles about every two years — researchers...

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...

Objects in our daily lives, such as speakers, refrigerators, and even cars, are becoming “smarter” day by day as they connect to the Internet and exchange data, creating the Internet of Things (IoT)....

NASA Langley Research Center has developed a new approach for designing aircraft liner cores for noise reduction. The cores are comprised of multiple honeycomb-shaped chambers,...

Titanium is as strong as steel but about twice as light. These properties depend on the way a metal's atoms are stacked, but random defects that arise in the...
