University of Delaware researchers have developed an inexpensive, nonchlorine- based technology that can remove harmful microorganisms, including viruses, from drinking water. The patented technology incorporates highly reactive iron in the filtering process to deliver a chemical "knock-out punch" to a host of notorious...

Small, universal mobile receivers are needed that are capable of receiving mobile satellite television signals. These receivers should be similar to those installed and used by satellite radio. The receivers will convert the signal from a satellite to a mounted or OEM satellite, thus delivering cable television to mobile...

Georgia Tech researchers have developed a new protoype engine that uses up to 40% less fuel by running on solar power while in space and by fine-tuning exhaust velocity.

The key to the engine improvements is the ability to optimize the use of available power. A traditional chemical rocket engine (attached to a...

Nanotech Briefs(R) magazine is now accepting nominations for its third annual Nano 50 awards competition. The Nano 50 recognizes the top 50

technologies, innovators, and products with the greatest potential to advance the commercialization of nanotechnology.

There is no cost to submit a...

Researchers have created carbon briquettes with complex nanopores capable of storing natural gas at a density of 180 times their own volume and at one- seventh the pressure of conventional natural gas tanks. The briquettes are the first technology to meet the 180 to 1 storage to volume target set by the U.S. Department of...

Researchers at the University of Illinois at Urbana-Champaign have developed a disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments.According to the researchers, the sensor provides a fast, on-site test for assessing uranium...

A fluorescent coating is needed to alter emitted wavelength from UV LEDs.

The goal of this project is to create a white light source with a uniform spectral output. Due to size and power constraints, LEDs are the preferred light source.

According to a recent report based on some of the first observations by NASA's Mars Reconnaissance Orbiter, fluids that flowed through cracks penetrating underground rock on ancient Mars may have produced conditions to support possible habitats for microbial life.

Researchers at the University of Michigan (U-M, Ann Arbor, MI) developed a robotic exoskeleton controlled by the wearer's own nervous system that could help users regain limb function. Healthy subjects first wore the exoskeleton to measure how the device affected ankle function before researchers tested the device on disabled...

Biologists at Yale University (New Haven, CT) are developing a process to trap viruses in habitats that force their extinction. Viruses are chemically lured into the wrong cells, thus preventing virus reproduction and alleviating disease. The research was conducted on phi-6 virus populations in environments containing different...

Three families of liquid-crystal polyester are available that can be used in the form of shaped articles, and can be prepared from the melt phase by extrusion, injection molding, compression molding, or other convenient means.

Engineers at Massachusetts Institute of Technology (MIT) have devised new analog circuits that will not drain power or create bottlenecks like previous models. The new class of analog circuits eliminates operational amplifiers while maintaining virtually all benefits of operational-amplifier-based circuits. The MIT circuits...

Case New Holland (CNH, Amsterdam, the Netherlands) has lessened the level of steering noise in the cabs of its 821 Case brand and LW190 brand wheel loaders by utilizing Char-Lynn Series 20 steering control unit from Eaton Hydraulics (Eden Prairie, MN). The cab noise issue was great enough to hold the assembly line while the matter...

A joint effort between University of Washington (Seattle, WA) and Case Western Reserve University (Cleveland, OH) researchers has revealed gyroscope-like structures in tobacco horn moth antennae that could lead to mechanical equivalents for miniature flying robots. The discovery allows the researchers to understand neural...

The Air Force's Technology Horizons magazine is now Defense Tech Briefs (DTB),providing engineers with a one-stop source for the latest advances and tech transfer opportunities from Defense Department R&D programs. Commercially promising inventions resulting from this work are reported in DTB magazine, published...

Technologies are needed for the economical production of polymers that are based on today's generally accepted standards for "green" chemistry. Of particular interest are chemistries that produce safe chemicals, and/or that use safer solvents and auxiliaries, and/or that produce chemicals designed for degradation.

Brown University researchers are creating a technology that will allow doctors and scientists to see inside living humans and animals, and watch their bones move in 3D as they run, fly, jump, swim, and slither. This high-resolution, high-speed imaging system will contribute to better treatments for knee, shoulder, wrist, and back...
