Since the disappearance of tobacco from bars, restaurants and pubs, customers of these places perceive more unpleasant odors, such as human sweat or beer, which used to be masked by cigarette smoke. Scientists from the Delft University of Technology in the Netherlands claim to have found a solution.
The coffee that is prepared in espresso machines and, above all, that of capsules, contains more furan - a toxic and carcinogenic compound - than that of traditional drip coffee machines, although always within safe levels for health. This is reflected in a study carried out by researchers from the University of Barcelona.
What if instead of resorting to fossil fuels, wind or nuclear energy we could obtain energy using leaves like those used by green plants to trap energy from the Sun? This is what Daniel Nocera, a chemist at the Massachusetts Institute of Technology, has just achieved, thus approaching the holy grail of artificial photosynthesis.
Brazilian scientists have developed an effective method to develop a new generation of plastics for making cars from banana and pineapple fibers. Its advantages? They are 3 to 4 times stronger, 30% lighter and much more environmentally friendly than plastics that are used today, as shown today at the Meeting of the American Chemical Association (AMC).
An international team of scientists has discovered a chemical reaction that explains why the intense yellows in the works of the Dutch painter Vincent Van Gogh turned brown, according to a study published in the journal 'Analytical Chemistry'.
The UN General Assembly has proclaimed 2011 as the International Year of Chemistry to raise public awareness about the contributions of this science to the well-being of humanity under the slogan "Chemistry: our life, our future" ("Chemistry: our life , our future".
A new study published in the open access journal "Chemistry Central Journal" reveals that chocolate contains more antioxidants, specifically in the form of polyphenols and flavonoids, than any fruit. This makes it a good ally against cellular aging.
This year is the Year of Chemistry and it seems no coincidence that a chemist has won the award. Somorjai, considered the father of modern surface chemistry, has risen with him "for his pioneering contributions to the understanding of surface chemistry and catalysis on a molecular scale", according to the minutes of the jury chaired by the Nobel Prize in Physics Theodor W. Hänsch.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
