Bacteria-Fighting Polymers Created with Light
Hundreds of polymers that could kill drug-resistant superbugs in novel ways can be produced and tested using light. The new method may help identify antimicrobials for a range of applications from personal care to coatings.
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: Photonics/Optics
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...

A Robust Waveguide Millimeter-Wave Noise Source
A noise source is an enabling technology for passive millimeter-wave remote sensing applications such as atmospheric sounding, and precipitation and ice cloud measurements. NASA Goddard Space Flight Center has developed a packaged noise source that will allow calibration of the front end at the...
Briefs: Imaging
Traditional cameras — even those on the thinnest cellphones — cannot be truly flat due to their optics. The lenses require a certain shape and size in order to function. A new camera design...
Briefs: Photonics/Optics
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: Photonics/Optics
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: Test & Measurement
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: Medical
An MIT-developed technology monitors blood glucose levels without needles or a finger prick. Early results show that the noninvasive technology measures blood glucose levels as...
Briefs: Data Acquisition
A technique was developed to quickly teach robots novel traversal behaviors with minimal human oversight. The technique allows mobile robot platforms to navigate autonomously in...
Briefs: Sensors/Data Acquisition
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...
Briefs: Robotics, Automation & Control
Given the exact parameters of the task at hand, a robot can assemble a car door or pack a box faster and more efficiently than a human, but such purpose-built machines are not suited...
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...
Briefs: Energy
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,...
Briefs: Photonics/Optics
A technique that enables on-demand control of composite behavior could enable a variety of new capabilities for future rotorcraft design, performance, and maintenance. The focus of the research was on...

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...

Configuration Enables RFID Tags to Work as Sensors
The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to non-target gases. Infrared (IR) absorption spectroscopy gives highly specific...

NASA's Langley Research Center, in collaboration with Michigan State University (MSU), has developed a microphone array that...
Briefs: Test & Measurement
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,...
Briefs: Manufacturing & Prototyping
Plastics are often derived from petroleum, contributing to reliance on fossil fuels, and driving harmful greenhouse gas emissions.
Briefs: Materials
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...
Briefs: Electronics & Computers
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...
Briefs: Sensors/Data Acquisition
When hit with light, semiconductors (materials that have an electrical resistance in between that of metals and insulators) generate an electric current....
Briefs: Electronics & Computers
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: Aerospace
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: Photonics/Optics
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...
