Synthesis and Development of Polyurethane Coatings Containing Fluorine Groups for Adhesive Applications
Accumulation of insect strikes on the leading edge of airplane wings is a more serious problem than one might realize. Depending on the magnitude, such accumulation changes the aerodynamic characteristics of the wing, causing a change from...
Briefs: Electronics & Computers
Colloids — insoluble particles or molecules anywhere from a billionth to a millionth of a meter across — are so small they can stay suspended indefinitely in a liquid or even in air. Robots about...
Briefs: Electronics & Computers
Quantum computers will be able to solve problems well beyond the reach of existing computers while working much faster and consuming vastly less energy. An inorganic compound was developed that...
Briefs: Materials
Current density is the amount of electrical current per cross-sectional area at a given point. As transistors in integrated circuits become smaller and smaller, they need higher and higher...
Briefs: Materials
Fabricated using inexpensive and widely available organic pigments used in printing inks and cosmetics, an artificial retina was developed that consists of tiny pixels like a digital camera sensor on a...

One current method to build a semiconductor superlattice — materials comprised of alternating layers of ultra-thin, two-dimensional sheets only one or a few...
Briefs: Communications
MIT researchers have designed an optical filter on a chip that can process optical signals from across an extremely wide spectrum of light at once, something never before...
Briefs: Sensors/Data Acquisition
An advanced, highly compact thermal camera that traces its heritage to one now flying on NASA's Landsat 8 has been mounted in a corner of NASA's next...
Briefs: Photonics/Optics
Researchers have developed a method to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a...

Researchers have 3D-printed an array of light receptors on a hemispherical surface. This discovery could lead to a “bionic eye” that could someday help blind people see or sighted...
Briefs: Transportation
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,...

Power Line Detection System for Unmanned Aircraft Systems
Electrical power lines pose a serious crash hazard to helicopters and other air-based vehicles, especially small aerial vehicles such as unmanned aircraft systems (UAS). This is because power lines are so widespread, hard to see, and strung at roughly the same height above the ground at...
Briefs: Motion Control
It is often desirable to sense the angular position of a rotating part. Numerous kinds of rotation sensors have been developed over the years; one type is a capacitive sensor, where a capacitance...

When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....
Briefs: Nanotechnology
Photons, or units of light, are faster than electrons and could, therefore, process information faster from smaller chip structures. A switch was designed that bypasses a...
Briefs: Transportation
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),...
Briefs: Semiconductors & ICs
Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened material...
Briefs: Electronics & Computers
Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...
Briefs: Aerospace
It's common to see line-shaped clouds in the sky, known as contrails, trailing behind the engines of a jet airplane. What's not always visible is a vortex coming off of the tip of each wing — like two...

Polymer Nanofiber-Based Reversible Nano-Switch/Sensor Schottky Diode (nanoSSSD) Device
Innovators at NASA's Glenn Research Center have developed a unique nano-structure device that operates as a nano-switch/sensor for detecting toxic gases and ultraviolet (UV) radiation. Conventional microsensors are limited by their short life, high cost and...
Briefs: Manufacturing & Prototyping
Additive manufacturing (3D printing) can be used to manufacture porous electrodes for lithium-ion batteries, but because of the nature of the manufacturing process, the design of these 3D-printed...
Briefs: Electronics & Computers
By stacking and connecting layers of stretchable circuits on top of one another, soft, pliable 3D stretchable electronics were fabricated that can pack a lot of functions while staying thin and small in...
Briefs: Mechanical & Fluid Systems
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,...

Technique Boosts Capacity of Computer Storage
The most dense solid-state memory ever created could soon exceed the capabilities of current computer storage devices by 1,000 times using a new technique. The same technology was used to manufacture atomic-scale circuits, allowing for quickly removing or replacing single hydrogen atoms. The technology...
