A SPICE module for the Satellite Orbit Analysis Program (SOAP) precisely represents complex motion and maneuvers in an interactive, 3D animated environment with support for user-defined quantitative outputs. (“SPICE” stands for Spacecraft, Planet, Instrument, Camera-matrix, and...

NASA Tech Briefs' National Nano Engineering Conference (NNEC) is the premier event focused on current and future developments in engineering innovations at the nanoscale, as well as the commercialization of nanotechnology. The event returns to Boston this year on November 12-13 at the Boston Colonnade Hotel, featuring the fourth annual Nano 50...

Scientists at the University of Pennsylvania have theorized a way to increase the speed of pulses of light that bound across chains of tiny metal particles to well past the speed of light by altering the particle shape. Under the theory, nanosized metal chains would serve as building blocks for high-frequency...

The proliferation of solar, wind, and tidal electric generation, and the emergence of hybrid electric automobiles demands flexible and reliable methods of high-capacity electrical storage. A team of Penn State materials scientists is developing ferroelectric polymer-based capacitors that can deliver power more rapidly, and...

Researchers from the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI), a collaborative center of the University of Maryland and NIST, have reported a new way to fine-tune the light coming from quantum dots, by manipulating them with pairs of lasers. The accomplishment could accelerate...

Purdue University researchers have harnessed the sensitivity of days-old fish embryos to create a fiber optic-based tool to detect a range of harmful chemicals. By measuring rates of oxygen use in developing fish, the technology could reveal the presence of minute levels of toxic substances. It could thus warn of environmental...

The pinhole camera has inspired a lens-less, three-dimensional imaging technology that produces some of the brightest, sharpest X-ray holograms of microscopic objects to date. The technology was developed by scientists at the Advanced Light Source of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, and at...

A new type of device called a "lab-on-a-chip" could result in a future generation of instant home tests for illnesses, food contaminants and toxic gases. But today these portable, efficient tools are often stuck in the lab themselves. Specifically, in the labs of researchers who know how to make them from scratch. University of...

Researchers at Ohio State University have invented a new material that will make cars even more efficient by converting heat wasted through engine exhaust into electricity. Scientists call such materials thermoelectric materials, and they rate the materials' efficiency based on how much heat they can convert into electricity at a...

Penn State researchers are investigating electrically induced heat effects of some ferroelectric polymers. "This is the first step in the development of an electric field refrigeration unit," says Qiming Zhang, professor of electrical engineering. "For the future, we can envision a flat panel refrigerator. No more coils, no...

A research team at Worcester Polytechnic Institute is developing a solar collector that could turn roads and parking lots into sources of electricity and hot water. Roads and parking lots are typically resurfaced every 10 to 12 years, so the massive acreage of already installed roads and lots could be retrofitted at that...

The information technology industry consumes as much energy and has roughly the same carbon footprint as the airline industry. Energy usage per compute server rack is growing from about 2 kilowatts (KW) per rack in 2000, to an estimated 30 KW per rack in 2010. Every dollar spent on power for IT equipment requires that another...

In computer simulations, researchers at the University of Illinois have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking. “When light of the correct wavelength strikes the...

Researchers at the California Institute of Technology have developed a compact, high-resolution microscope small enough to fit on a finger tip. Dubbed an optofluidic microscope, the device operates without lenses but has the magnifying power of a top-quality optical microscope. It can be used in the field to analyze samples or...
