A team of researchers with members from the U.S., Germany and Sweden has discovered that the cellulose found in bacterial biofilms differs from the cellulose in plants. In their paper published in the journal Science, the ...
Where do the molecules required for life originate? It may be that small organic molecules first appeared on earth and were later combined into larger molecules, such as proteins and carbohydrates. But a second possibility ...

(Phys.org)—A team of researchers from China and the U.S. has devised a relatively simple means for measuring the shear forces that exist between sheets of graphene and other materials. In their paper published in the journal ...
Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first direct measurements, and by far the most precise ones, of how electrons move in sync with atomic vibrations ...

(Phys.org)—Ferrocene is the model compound that students often learn when they are introduced to organometallic chemistry. It has an iron center that is coordinated to the π electrons in two cyclopentadienyl rings. (C5H5- ...
A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing ...
