Typical direct-injection engines, such as diesel engines, can produce soot due to fuel-rich combustion conditions. Filters and catalytic converters are currently used to reduce soot and harmful...

Engineers and software developers are seeking to create technology that lets users touch, grasp, and manipulate virtual objects while feeling like they are actually touching something in...

NASA's Langley Research Center has developed the SHEARLESS composite boom with a final cross-section shape that is lenticular and is flexible enough to...

Gas turbine blades of conventional rotorcraft turboshaft engines are optimized to operate at nearly a fixed speed and a fixed incidence angle. If the operating condition of the engine changes, then the flow...

Most naturally occurring materials have a disordered atomic structure that interferes with the propagation of both sound and electromagnetic waves. When the waves come into contact with these...

Researchers have developed a new propulsion concept for swimming robots that exploits temperature fluctuations in the water for propulsion without the need for an engine, propellant, or power supply.

Robots that are adapted to respond to physical human-robot interaction (pHRI) traditionally treat such interactions as disturbances, and resume their original behaviors when the...

With novel optoelectronic chips and a new partnership with a top silicon-chip manufacturer, MIT spinout Ayar Labs aims to increase speed and reduce energy consumption in computing, starting with...

When heated, popcorn can expand more than 10 times in size, change its viscosity by a factor of 10, and transition from regular to highly irregular granules with surprising force. These unique qualities can...

NASA's Langley Research Center, in collaboration with Michigan State University (MSU), has developed a microphone array that...

NASA's Marshall Space Flight Center is offering opportunities for its new fiber optic mass flow sensor system. Capable of measuring multi-phase flows in a pipe, the technology is minimally invasive,...

A process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue lays the foundation for soft active matter with highly...

Wearable technologies are exploding in popularity in both the consumer and research spaces, but most of the electronic sensors that detect and transmit data from wearables are made of hard,...

The exhaust heat recovery system (EHRS) in an automobile captures the thermal energy from exhaust and transfers it to the engine coolant. As the car warms up,...

As the demand for air transportation increases, the capacity of the current U.S. ATM system will eventually be stressed to its limits. New technologies in communication, navigation, and surveillance (CNS),...

A device and method have been developed to conduct compression and tensile tests on soft materials such as flocculated sediments, biopolymers, biological materials, and food stuffs. The device...

The measurement of mechanical behavior in very small samples whose dimensions are on the order of microns and below can offer advantages over conventional macroscopic testing in many instances. Motivations for investigating...

The Army uses robots that are structurally rigid, making them impractical when performing military operations in highly congested and contested urban environments where covert maneuvering is critical...

Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides. Because the printing approach can also fabricate...

A battery pack is only as strong as its weakest cell. As battery packs become larger and more integral to the stable operation of devices and systems, the need to monitor battery dependability and performance...

The Department of Energy's Oak Ridge National Laboratory has developed a direct-current detector technology to help emergency responders safely detect high voltages, which they have...

Magnetic sensors play a key role in a variety of applications, such as speed and position sensing in the automotive industry and in biomedical applications....
