Conductive plastics made from natural, renewable, environmentally friendly soybeans Polymer matrix composites with carbon black are very interesting materials. This is because the carbon black can be used as filler material and can beneficially modify the electrical and mechanical properties of the used matrixes. view more (2007-05-30)
Coal and black liquor can produce energy from papermaking Adding a little coal and processing the papermaking industry's black liquor waste into synthesis gas is a better choice than burning it for heat, improves the carbon footprint of coal-to-liquid processes, and can produce a fuel versatile enough to run a cooking stove or a truck, according to a team... view more (2007-08-21)

Black carbon pollution emerges as major player in global warming Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal... view more (2008-03-24)
Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood. view more (2005-10-10)
From trees to high-performance ceramics When a racing driver brakes, the discs and linings become red-hot.

Increased atmospheric carbon dioxide promotes algal growth It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters,... view more (2004-05-13)

The Last Cry Of Matter 'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be... view more (2003-11-27)
No matter their size black holes 'feed' in the same way Research by UK astronomers, published today in Nature (7th December 2006) reveals that the processes at work in black holes of all sizes are the same and that supermassive black holes are simply scaled up versions of small Galactic black holes. view more (2006-12-07)

Invititation to the Media - Soils as carbon sinks-a breathing space in the race against global warming? Can we use land carbon sinks as a way to buy time for the restructuring of our energy generation? "We estimate soil carbon sinks could mitigate 8% of the EU`s emissions if major changes were made in land use and agricultural management ," says Professor David Powlson of IACR Rothamsted. However;... view more (2002-06-26)
