COLLEGE PARK, Md., April 26 /PRNewswire-USNewswire/ -- Anyone who has ridden behind a truck belching black exhaust knows the smell and discomfort caused by soot, the airborne carbon particles that result from the incomplete combustion of hydrocarbons such as diesel fuel. Those soot particles remain in the body beyond the moment of discomfort and can lead to lung diseases and other conditions. Peter Sunderland, assistant professor of fire protection engineering at the University of...

Soot from fire in an unventilated fireplace wafts into a home and settles on the surfaces of floors and furniture. But with a quick fix to the chimney flue and some dusting, it bears no impact on a home's long-term environment. A new modeling study from NASA confirms that when tiny air pollution particles we commonly call soot "“ also known as black carbon "“ travel along wind currents from densely populated south Asian cities and accumulate over a climate hotspot called the...

Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities. Temperatures on the Tibetan Plateau -- sometimes called Earth's "third pole" -- have warmed by 0.3°C (0.5°F) per decade over the past 30 years, about...

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...

SAN DIEGO, Dec. 1 /PRNewswire/ -- After a careful evaluation, Volkswagen (Ticker:VOWG) has become the first German automaker to join the esteemed Model Fuels Consortium II (MFC-II). The initial phase of the Model Fuels Consortium was launched four years ago by Reaction Design, the clean technology chemistry leader, to enable the design of cleaner-burning, more-efficient engines and fuels. Volkswagen is particularly interested in the Consortium's focus on modeling the combustion of both...

Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot, a new study has found.Like a black car on a bright summer day, soot absorbs solar energy. Recent atmospheric models have ranked soot, also called black carbon, second only to carbon dioxide in potential for atmospheric warming. But particles, or aerosols, such as soot mix with other chemicals in the atmosphere, complicating estimates of their...

Swedish and Indian researchers constrain the sources of climate- and health-afflicting soot pollution over South Asia A gigantic brownish haze from various burning and combustion processes is blanketing India and surrounding land and oceans during the winter season. This soot-laden Brown Cloud is affecting South Asian climate as much or more than carbon dioxide and cause premature deaths of 100 000s annually, yet its sources have been poorly understood. In this week's issue of Science...

Part of the changing climate, earlier spring snowmelt could affect hydropower generation, agriculture Soot from pollution causes winter snowpacks to warm, shrink and warm some more. This continuous cycle sends snowmelt streaming down mountains as much as a month early, a new study finds. How pollution affects a mountain range's natural water reservoirs is important for water resource managers in the western United States and Canada who plan for hydroelectricity generation, fisheries and...

NEW YORK (AP) -- A 12-year-old girl just wanted to show her cousin the view from her family's Manhattan rooftop. Instead, she fell into a chimney and plummeted down the flue for 14 stories, emerging nearly unscathed to tell her story after landing in a pile of furnace soot. Grace Bergere, a young rock drummer, was recovering at a hospital on Saturday with an injured hip. A 2-foot-deep pile of ash and dust probably saved her life by cushioning her fall when she crashed into a basement...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
