Fuel from fiber -- Pretreatment can put corn stalks, trees in your car's tank

..., we can expect to completely replace gasoline and diesel with cellulose-derived biofuels that are cheaper, better for the environment and much better for national security than petroleum-derived fuels," Dale said....

New biofuels process promises to meet all US transportation needs

...concept economically competitive with gasoline and diesel fuel would require research in two areas: finding ways to produce cheap hydrogen from carbon-free sources and developing a new type of gasifier needed for the process. "Having said that, this is the first concept for creating a sustainable system ...

Biodiesel won't drive down global warming

...rapeseed was instead used to grow trees, petroleum diesel would emit only a third of the CO2 equivalent emissions as biodiesel. Petroleum diesel emits 85% of its greenhouse gases at the final stage, when burnt in the engine. By contrast, two-thi...

Environmental toxins may cause body's defenses to worsen lung disease

... an air pollutant found in tobacco smoke, smog and diesel exhaust--to determine how cells respond to infection and toxicant-induced cell damage. "By looking at how the cells react to these stimuli, we hope to gain insight into what triggers and mediates the immune system response," Borchers says. This w...

Firefighters face increased risk for certain cancers

... for Research on Cancer (IARC)--including benzene, diesel engine exhaust, chloroform, soot, styrene and form...scene of a fire and in the firehouse, where idling diesel fire trucks produce diesel exhaust. "Firefighters work in an inherently dangerous occupation on a...

Key to lung cancer chemo resistance revealed

... environmental pollutants like cigarette smoke and diesel exhaust by absorbing the materials and pumping them out of the cell. Another gene called KEAP1 encodes products that stop this cleansing process. But lung cancer cells sabotage the expression of these same genes to block assault from chemotherapy d...

Green diesel: New process makes liquid transportation fuel from plants

... liquid alkanes resulting in an ideal additive for diesel transportation fuel. Co-researchers include chemical and biological engineering graduate students George Huber, Juben Chheda and Chris Barrett. "It's a very efficient process," says Huber. "The fuel produced contains 90 percent of the energy found i...

Green catalyst destroys pesticides and munitions toxins, finds Carnegie Mellon University

...mical-manufacturing plants. They are also found in diesel exhaust particles. Thousands of tons of these agents are produced yearly by countries around the world. Registered as priority pollutants by the EPA, they are toxic to aquatic life. They produce immediate toxic effects to the nervous system, and some...
