Briefs: Mechanical & Fluid Systems
NASA's Glenn Research Center developed a novel means of articulating the outboard portion of an aircraft wing to create the optimal geometry for given flight conditions. The Spanwise Adaptive Wing (SAW) concept employs a...
Briefs: Materials
Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains still...
Briefs: Materials
For many highly stressed engineering applications like bearings and gears, contaminated steel parts can lead to devastating outcomes such as an emergency shutdown or the end of a mission. Ensuring that these critical...
Briefs: Electronics & Computers
Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with respect...

Composite Material Cools Itself Down Under Extreme Temperatures
A material, inspired by nature, can regulate its own temperature and could be used to treat burns and help space capsules withstand atmospheric forces. The research used a network of multiple microchannels with active flowing fluids (fluidics) as a method and proof-of-concept to...
Briefs: Sensors/Data Acquisition
Lasers play roles in many manufacturing processes, from welding car parts to crafting engine components with 3D printers. To control these tasks, manufacturers must ensure that their lasers fire at the...
Briefs: Photonics/Optics
A technique was developed that uses a specially adapted 3D printer to build therapeutic biomaterials from multiple materials. The advance could be a step toward on-demand printing of complex...
Briefs: Medical
A low-cost 3D bioprinter was built by modifying a standard desktop 3D printer with a syringe-based, large volume extruder (LVE). The extruder works with most open-source fused deposition modeling (FDM)...

Vertical Take Off and Landing (VTOL) Aircraft with Vectored Thrust for Control and Continuously Variable Pitch Attitude in Hover
Most fixed-wing VTOL unmanned aerial vehicles (UAVs) take off vertically, then transition to horizontal flight. This is a new type of UAV that has unique capability. It can vary its hover position from “nose up”...
Briefs: Materials
Innovators at NASA's Glenn Research Center have designed a superior seal assembly that is durable and highly dependable in extremely harsh environments. This...
Briefs: Sensors/Data Acquisition
Researchers have developed a new ultrasound transducer that could dramatically lower the cost of ultrasound scanners to as little as $100. Conventional ultrasound scanners use piezoelectric crystals to...
Articles: Materials
Ultrashort pulse (USP) lasers for precision micromachining can minimize or avoid undesirable thermal effects that limit feature resolution, edge quality and, ultimately, product functionality. This is because...

Reusable Breakaway Mounting Device
Breakaway devices are used to mount objects to systems or structures (for example, cars, drones, helmets, buildings) and prevent damage when the objects fall away from the system. Unfortunately, even in ideal scenarios, many of these devices have limitations. Breakaway bolts and shear pins have the complication of...
Briefs: Power
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.
Briefs: Medical
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...
Briefs: Aerospace
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 through...
