Sound turns liquid to jelly
Japanese researchers have devised a method, using a burst of ultrasound waves, to turn a range of oily liquid solutions to jelly. And a blast of heat reverses the gel back to a liquid. The technology could be used to remotely control the viscosity of liquid shock absorbers in cars or to temporarily solidify liquids whilst being transported, to prevent leakages. (2005-06-22)

Hydrogen sensors are faster, more sensitive
The same kind of chemical coating used to shed rainwater from aircraft and automobile windows also dramatically enhances the sensitivity and reaction time of hydrogen sensors. Hydrogen sensor technology is a critical component for safety and other practical concerns in the proposed hydrogen economy. For example, hydrogen sensors will detect leaks from hydrogen powered cars and fueling stations long before the gas becomes an explosive hazard. (2005-05-26)

AAES honors outstanding engineers, recognizes top reporting at 26th annual awards ceremony
The American Association of Engineering Societies (AAES) recognizes the outstanding achievements of six U.S. engineers and a journalist on Monday, 9 May, at its 26th annual awards ceremony, in the Great Hall of the National Academy of Engineering in Washington, D.C. (2005-05-09)

Purdue finding could help develop clean energy technology
Chemical engineers at Purdue University have made a discovery that may help to improve a promising low-polluting energy technology that combusts natural gas more cleanly than conventional methods. Findings were detailed in a paper presented during a meeting of the American Chemical Society in San Diego. (2005-03-15)

Tiny particles could solve billion-dollar problem
New research from Rice University's Center for Biological and Environmental Nanotechnology finds that nanoparticles of gold and palladium are the most effective catalysts yet identified for remediation of one of the nation's most pervasive and troublesome groundwater pollutants, trichloroethene or TCE. The research, conducted by engineers at Rice and the Georgia Institute of Technology, will appear next month in the journal Environmental Science and Technology, a publication of the American Chemical Society.

NETL and Carnegie Mellon team up to create new paradigms for hydrogen production
The Department of Energy's National Energy Technology Laboratory (NETL) and Carnegie Mellon University have developed a new computational modeling tool that could make the production of hydrogen cheaper as the United States seeks to expand its portfolio of alternative energy supplies. (2005-01-27)

Titania nanotube hydrogen sensors clean themselves
Self-cleaning hydrogen sensors may soon join the ranks of self-cleaning ovens, self-cleaning windows and self-cleaning public toilets, according to Penn State researchers. (2004-03-24)

The key in the catalyst
A USC team may have found a better way to create acetic acid, used in aspirin, cosmetics and other essential products. The process could lead to cheaper ways to convert natural gas - one of the planet's most abundant resources. (2003-08-07)

Chapel Hill chemist wins national award for innovations in plastics
Maurice S. Brookhart of Chapel Hill, N.C., will be honored March 25 by the American Chemical Society for developing novel approaches to making new types of polymers, or plastics. He will receive the 2003 Award in Polymer Chemistry at the Society's national meeting in New Orleans. (2003-03-04)

Water world: The sequel
Scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) have produced the first ever action movies starring individual water molecules on a metal surface. The ending was a surprise even to the producers. (2002-09-16)

New research turns sewage farms into power plants
Researchers at the University of Warwick's Warwick Process Technology Group have devised a process that turns wet waste from sewage farms and paper mills into a source of power. (2002-04-30)

Josephson synthesizer circuit demonstrated
Electrical engineers would love to have a waveform synthesizer using Josephson junctions to provide precisely defined output voltages, frequencies and waveforms of any arbitrary shape. NIST researchers recently demonstrated a circuit that marks a major step toward realizing such a synthesizer. This story from the January 22, 2002 issue of the NIST UPDATE newsletter tells about what they have achieved. (2002-01-29)

Output from major platinum-group metals producer could increase
Russian production of platinum-group metals (PGM) could increase by more than 40% in the next few years, according to a U.S. Geological Survey study in Post Soviet Geography and Economics. The future supply and price of PGM will affect development of pollution reducing technologies as PGM are essential in producing automobile catalytic converters. Palladium prices soared in the past year, partly from concerns regarding reduced exports from Russia. (2001-04-16)

New chemical instrument uses advanced missile technology
Purdue engineers, using heat-seeking missile technology, have developed an instrument that dramatically speeds up the search for new catalysts that could improve chemical manufacturing processes and automotive pollution-control systems. (2000-05-01)

Study: Methane cleans nitric oxide from power plant emissions
Engineers have learned to use methane to remove toxic nitric oxide emissions from the stack gases of coal-burning power plants. This new method of catalytically reducing nitric oxide with methane removes up to 100 percent of nitric oxide from stack gases in a safer, less expensive way than currently available. (2000-03-05)

Yale prostate cancer study shows newer implant therapy has fewer side-effects, could lead to better treatment outcomes
A Yale study of complication rates from two radiation implant therapies for prostate cancer shows that the newer therapy, Palladium-103, has fewer long-term side effects than Iodine- 125, an older, more commonly prescribed therapy. (1999-10-28)

Material that made car bumpers shine finds a role in manufacture of drugs, dyes
Chemists have a gleam in their eyes--from the reflection of chrome bumpers that adorn classic roadsters. The raw material at the root of the bumpers' sheen, chromium, is helping chemists leapfrog into the future by providing an automated way to create hundreds of thousands of compounds in a few easy steps. (1999-10-25)

Dual X-Ray Technique Analyzes Structure Of Dental Alloys
Researchers at Ohio State University have employed a combination of two X-ray techniques to discover new information about the structure of oxide layers on dental alloys. With this knowledge, manufacturers of alloys for crowns, bridges, and other dental restorations can explore stronger dental materials. (1998-09-01)

Levitating Furnace Holds Promise For Future Experiments
A unique levitation furnace that flew on the Space Shuttle in 1998 is being eyed for upgrades to fly on future Shuttle and International Space Station missions, based on science results presented this week at third Biennial Microgravity Materials Science Conference in Huntsville, Alabama. (1998-07-15)

Citing Growth Patterns, Researchers Dispute Claims Of Nanofossils In Martian Meteorite
In a paper to be published in the July issue of Meteoritics and Planetary Science, researchers say crystals in a Martian meteorite were formed by epitaxial processes at temperatures that were likely too high for biological organisms to exist. Thus they dispute claims of other researchers that the meteorite contains (1998-07-06)
