Lightweight Sensing and Control System for Unmanned Aerial Vehicle Monitoring

A new sensing and control system for unmanned aerial vehicles (UAVs) allows for semi-autonomous flight. Pilots need not leave the ground to conduct routine monitoring and surveillance quickly and cost-effectively. Such systems are particularly useful during long flight...

A new device, inspired by a rose, inexpensively collects and purifies water. The device is a new approach to solar steaming for water production — a technique that uses energy from sunlight...

Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact,...

Semi-Liquid Metal Anode for Next-Generation Batteries

Researchers from Carnegie Mellon University have developed a semi-liquid lithium metal-based anode. Lithium batteries made using this new...

This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. To learn more about each technology, see the contact information provided for that...

NASA Langley Research Center has developed a double-sided Si(Ge)/ Sapphire/III-Nitride hybrid structure. This technology uses both sides of a sapphire wafer to build device...

Organic semiconductors (OSCs) have emerged as a new class of electronic materials promising a wide range of applications including organic field-effect transistors...

The color of a material can often tell how it handles heat. With clothing, for example, the darker the pigment, the warmer you're likely to feel on a hot day. Likewise, the more...

How to Produce More Clean Water? Resemble the Rose.
A new water purifier works better because it takes the shape of the rose.

Solar power researchers have traditionally only used the power measurements from single residential solar photovoltaic (PV) systems to estimate the...

By adding utility-scale solar farms throughout New York state, summer electricity demand from conventional sources could be reduced by up to 9.6% in some places. But...

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...
