Fool's gold may prove an unlikely alternative to overexploited catalytic materials Catalytic materials, which lower the energy barriers for chemical reactions, are used in everything from the commercial production of chemicals to catalytic converters in car engines. However, with current catalytic materials becoming increasingly expensive, scientists are exploring viable alternatives. Researchers at the University of Cambridge have now discovered that the sulphide material iron pyrite,...

The harmful effects of ozone that exist at low levels in the earth's atmosphere can be reduced when charging is done at night for electric vehicles, a new study has found. In the stratosphere, ozone becomes a protective layer of film that filters out ultraviolet rays that can cause skin cancer and DNA mutations in plants, reports AFP. However, ozone that is formed from the reaction between hydrocarbons and nitrogen oxide with sunlight can irritate the airways of people with cardiac or...

Reactive Nitrogen Causes Much Higher Climate-damaging Nitrous Oxide Emissions in European Forests than Previously Estimated by the IPCC Reactive nitrogen compounds from agriculture, transport, and industry lead to increased emissions of the greenhouse gas nitrous oxide (N2O) from forests in Europe. Nitrous oxide emission from forest soils is at least twice as high as estimated so far by the Intergovernmental Panel on Climate Change (IPCC). This is one of the key messages of the first study on...

Researchers from Purdue University and Cummins Inc. have developed an advanced "closed-loop control" approach for preventing diesel engines from emitting greater amounts of smog-causing nitrogen oxides when running on biodiesel fuels. Operating truck engines on a blend of biodiesel and ordinary diesel fuel dramatically reduces the emission of particulate matter, or soot. However, the most modern and efficient diesel engines burning biodiesel emit up to 40 percent more nitrogen oxides at some...

Diesel's alma mater drives engine technology toward green extreme Just three months after the Euro 5 Norm for exhaust emissions went into force for all new car models, researchers at the Technische Universitaet Muenchen (TUM) have demonstrated an engine that is already close to meeting the more stringent Euro 6 emissions standard. A research team headed by Prof. Georg Wachtmeister from the Chair of Internal Combustion Engines has succeeded in reducing the pollutants in exhaust emissions to...

Every year, scientists learn something new about the inner workings of lightning. With satellites, they have discovered that more than 1.2 billion lightning flashes occur around the world every year. (Rwanda has the most flashes per square kilometer, while flashes are rare in polar regions.) Laboratory and field experiments have revealed that the core of some lightning bolts reaches 30,000 Kelvin (53,540 ºF), a temperature hot enough to instantly melt sand and break oxygen...

Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely overlooks. The study, which suggests that government officials adapt a more comprehensive pollution control strategy that includes a new emphasis on...

NOAA has released the first-ever study of the climate impacts of the man-made substance, nitrous oxide. Researchers A.R. Ravishankara, J.S. Daniel and Robert W. Portmann of the National Oceanic and Atmospheric Administration's Earth System Research Laboratory (ESRL), said that nitrous oxide, also known as laughing gas, has become the largest ozone-depleting substance emitted through human activities. Additionally, the gas is expected to continue its status through the 21st century. "Nitrous...

Word of the Day
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
