By utilizing a conductor made from a proprietary base-metal alloy instead of platinum, Kyocera has developed a sensing element that can detect soot
at high operating temperatures.
Overtime the trapped soot
builds up inside the filter and clogs it.
He also shows how their discovery can be used as flame retardant by putting a cigarette lighter to a cloth that has been made with the carbon "nanotubes" that have been collected after processing the exhaust soot
There are extensive researches on the effective parameters on the PMs and diesel soot
Along with the melting, researchers believe that there is a second environmental effect that is darkening polar ice: soot
from wildfires, which may be becoming more common in the Arctic.
Study co-author Piers Forster, PhD, of the University of Leeds School of Earth and Environment in the United Kingdom, said opportunities exist to combat global warming by reducing soot
To find evidence of soot
deposition from these fires, Box and his team first used thermal images from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) to identify large fires in the region.
After a balanced debate with messages in support of and opposition to the stricter standards on soot
released by industrial facilities-including a discussion on the economic and health impacts of the proposal-a majority of Americans continue to support the plan by a large 20-point margin, 56 - 36 percent.
Non-smokers also breathe in soot
, sometimes known as particulate matter.
, made up of a mixture of coal dust and oil residue, blanketed cars, rooftops and rice paddies in the town of Sanyi.
Scientists say carbon dioxide from fossil fuels like coal and oil is a bigger overall cause of global warming, but reducing methane and soot
offers quicker fixes.
