Commercial ships spew half as much particulate pollution as world's cars
Globally, commercial ships emit almost half as much particulate pollution into the air as the total amount released by cars, according to a new study. Ship pollutants affect both the Earth's climate and the health of people living along coastlines. view more (2009-02-27)
Device Burns Fuel with Almost Zero Emissions
Georgia Tech researchers have created a new combustor (combustion chamber where fuel is burned to power an engine or gas turbine) designed to burn fuel in a wide range of devices — with next to no emission of nitrogen oxide (NOx) and carbon monoxide (CO), two of the primary causes of air pollution. view more (2006-06-22)
Engineers perfecting hydrogen-generating technology
Researchers at Purdue University have further developed a technology that could represent a pollution-free energy source for a range of potential applications, from golf carts to submarines and cars to emergency portable generators. view more (2007-08-28)
Asthma linked to soot from diesel trucks in Bronx
Soot particles spewing from the exhaust of diesel trucks constitute a major contributor to the alarmingly high rates of asthma symptoms among school-aged children in the South Bronx. view more (2006-10-17)
Brookhaven lab scientists stabilize platinum electrocatalysts for use in fuel cells
Platinum is the most efficient electrocatalyst for accelerating chemical reactions in fuel cells for electric vehicles. In reactions during the stop-and-go driving of an electric car, however, the platinum dissolves, which reduces its efficiency as a catalyst. This is a major impediment for vehicle-application of fuel cells. view more (2007-01-15)
Why eating less can help the environment
An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. view more (2008-07-24)
Oxygen ions for fuel cells get loose at low(er) temperatures
Seeking to understand a new fuel cell material, a research team working at the National Institute of Standards and Technology (NIST), in collaboration with the University of Liverpool, has uncovered a novel structure that moves oxygen ions through the cell at substantially lower temperatures than previously thought possible. view more (2008-06-30)
Electricity from straw
Researchers have developed the first-ever biogas plant to run purely on waste instead of edible raw materials - transforming waste into valuable material. view more (2009-02-03)
Sparks spell danger - The Physics Congress 2003
An effective new approach to preventing sparks when an electrically charged object is earthed could prevent explosions and save lives following a motorway smash involving fuel tankers or other hazardous vehicles. Dr Klaus Schwenzfeuer of the Electrostatic Laboratory at the Swiss Institute for the Promotion of Safety & Security in Basle, will... view more... (2003-03-17)
A promising step towards more effective hydrogen storage
An international research team led by Swedish Professor Rajeev Ahuja, Uppsala University, has demonstrated an atomistic mechanism of hydrogen release in magnesium nanoparticles - a potential hydrogen storage material. The findings have been published in the online edition of Proceedings of the National Academy of Science (PNAS). view more (2008-06-17)
Got Sugar? Glucose Affects Our Ability to Resist Temptation
New research from a lab at Florida State University reveals that self-control takes fuel-- literally. When we exercise it, resisting temptations to misbehave, our fuel tank is depleted, making subsequent efforts at self-control more difficult. view more (2007-12-04)
Gold, copper nanoparticles take center stage in the search for hydrogen production catalysts
X-ray studies at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are pointing the way to less costly and more efficient catalysts for improving the performance of fuel cells. view more (2007-03-29)
Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. view more (2007-12-11)
Argonne scientists reveal interaction between supersonic fuel spray and its shock wave
Shock waves are a well tested phenomenon on a large scale, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators from Wayne State University and Cornell University have made a breakthrough that reveals the interaction between shockwaves created by high-pressure supersonic fuel jets. view more (2009-03-13)
Exposures to metals and diesel emissions in air linked to respiratory symptoms in children
Exposure shortly after birth to ambient metals from residential heating oil combustion and particles from diesel emissions are associated with respiratory symptoms in young inner city children. view more (2009-11-24)
Danish researchers design the first virtual nano-catalyst in the world
Research offers new opportunities in the fields of renewable energy, pollution control and in the chemical industry. view more (2005-01-28)
Robotic assembly of fuel cells could hasten hydrogen economy
"The U.S. Department of Energy has suggested that the cost of manufacturing fuel cells is the single biggest obstacle on the road to the hydrogen economy," says Raymond Puffer, co-director of the FMC. view more (2005-11-09)
Chandrayaan-1 now in lunar transfer trajectory
Yesterday, following a fifth orbit-raising manoeuvre, the Chandrayaan-1 spacecraft successfully settled into a trajectory that will take it to the Moon. view more (2008-11-06)
Researchers collaborate to understand phenomena controlling PEM fuel cell performance, durability
Two researchers at Sandia National Laboratories are working to understand several key phenomena that control hydrogen-fueled PEM (proton exchange membrane or polymer electrolyte membrane) fuel cells. One, Ken S. Chen, is developing computational models to describe the phenomena while the other, Mike Hickner, is performing physical experimentation. view more (2006-01-27)
Industry Leader Calls for Moves Toward a Hydrogen Economy
Chris Clark, chief executive of Johnson Matthey, last night called on legislators to assess urgently future sustainable energy targets and technology. He was speaking in London on acceptance of the SCI Centenary Medal, which recognises excellence and achievement in the global science and business arena. From his perspective at the head of Johnson... view more... (2002-05-23)
