Natural-Gas Autos

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...

Disposable Sensor

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...

Tech Needs

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.

Robotic Exoskeleton

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...

Viral Traps

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.

Analog Circuits

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...

Steering Unit

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...
