Mechanical systems such as engines and motors rely on two principal types of motions of stiff components: linear motion, which involves an object moving from one point to another in a straight...

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

By mixing carbon fibers into polymer-based brakes, researchers designed brakes that are self-lubricating. These new and improved brakes can prevent wear-and-tear and have better frictional...

A metal-organic framework (MOF) material was developed that exhibits a selective, fully reversible, and repeatable capability to remove nitrogen dioxide gas from the atmosphere in ambient...

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...

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...

Researchers, drawing inspiration from bacteria, have designed smart, bio-compatible microrobots that are highly flexible. Because these devices are able to swim through fluids and modify their shape...

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

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...

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)....

Traditional methods, such as reverse osmosis, that remove contaminants from water are expensive and energy-intensive. Researchers have developed technology to remove contaminants from water,...

A customizable nanomaterial was developed that combines metallic strength with a foam-like ability to compress and spring back. The material can store and release mechanical energy on the nanoscale, and...

Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging, and Light Detection and Ranging (LIDAR) systems. In the...

Inspired by the human eye, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed an adaptive metalens that is essentially a flat,...

It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials,...

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...

Liquid droplets are used in many applications, from printing ink on paper to creating microcapsules for drug delivery. Inkjet printing is the most common technique used...

RTM370 imide resin was developed to address the limitations of conventional imide resins, which are generated from commercially available symmetrical biphenyl...

Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take more than a month per engine. Many components are located deep...

A novel foot-pedal-operated system and device were developed to control translational and rotational movement of an object in three-dimensional (3D) space. The Foot Pedal Controller system enables operators to control...
