Bioplastic – greener than ever

Polylactic acid is a degradable plastic used mostly for packaging. To meet the rising demand, ETH researchers have developed an eco-friendly process to make large amounts of lactic acid from glycerol, a waste by-product in ...

Key building block of life may have come from deep space

Researchers at UH Mānoa's Department of Chemistry have provided compelling evidence that glycerol, a key molecule in the origin of Earth's living organisms, may have occurred in space more than 4 billion years ago. Glycerol ...

Water-cleanup catalysts tackle biomass upgrading

Rice University chemical engineer Michael Wong has spent a decade amassing evidence that palladium-gold nanoparticles are excellent catalysts for cleaning polluted water, but even he was surprised at how well the particles ...

New, fossil-fuel-free process makes biodiesel sustainable

A new fuel-cell concept, developed by an Michigan State University researcher, will allow biodiesel plants to eliminate the creation of hazardous wastes while removing their dependence on fossil fuel from their production ...

First steps towards achieving better and cheaper biodiesel

Is there any connection between wine and biodiesel? The answer is yes, however surprising it may seem. Acetals are chemical compounds found in many wines, like port, for example, which give it a unique, sweet smell. However ...

Yeast uses CO2 to boost bioethanol production

Introducing four genes from bacteria and spinach has enabled researchers at the Delft University of Technology to improve the production of bioethanol with yeast by using carbon dioxide. Their findings were published last ...

Alaskan wood frogs stock up on solutes to survive

Outwardly, the tiny wood frog, Rana sylvatica, does not look like your regular arctic inhabitant. Yet despite their tiny stature, these little frogs are actually quite hardy and can tolerate freezing of up to two-thirds of ...
