Hydrogen advances graphene use
18-01-2012
Physicists at Linköping University have shown that a dose of hydrogen or helium can render the "super material" graphene even more useful. Graphene has engendered high expectations whereof its extreme properties depend on the fact that it consists of a single sheet of carbon atoms. However ...
Graphene mixer can speed up future electronics
05-01-2012
Researchers at Chalmers University of Technology have for the first time demonstrated a novel subharmonic graphene FET mixer at microwave frequencies. The mixer provides new opportunities in future electronics, as it enables compact circuit technology, potential to reach high frequencies and ...
BPA banned in baby bottles but used in drinking water pipes
16-12-2011
Since the spring of 2011 Bisphenol A (BPA) is banned in baby bottles throughout the EU, and lately the presence of this chemical in food tin cans has been increasingly questioned. However, there is also the risk of BPA leaching into drinking water from water pipes being restored with a method ...
Nobel Prize in Chemistry 2011 awarded for the discovery of quasicrystals
A remarkable mosaic of atoms
05-10-2011
In quasicrystals, we find the fascinating mosaics of the Arabic world reproduced at the level of atoms: regular patterns that never repeat themselves. However, the configuration found in quasicrystals was considered impossible, and Daniel Shechtman had to fight a fierce battle against ...
Written in the stars: The Nobel Prize in Physics 2011 given to three scientists
The 2011 Nobel Prize in Physics is awarded "for the discovery of the accelerating expansion of the Universe through observations of distant supernovae"
04-10-2011
What will be the final destiny of the Universe? Probably it will end in ice, if we are to believe this year's Nobel Laureates in Physics. They have studied several dozen exploding stars, called supernovae, and discovered that the Universe is expanding at an ever-accelerating rate. The ...
Bimetallic nanoantenna separates colors of light
30-09-2011
Researchers at Chalmers University of Technology have built a very simple nanoantenna that directs red and blue colours in opposite directions, even though the antenna is smaller than the wavelength of light. The findings – published in the online journal Nature Communications – can lead to ...
Mix of hazardous chemicals under your bed
16-09-2011
ChemSec, together with the Swedish Society for Nature Conservation (SSNC) and other NGOs, have analysed dust in bedrooms across the EU, Africa and Asia. The resulting report, Home sweet home - dusty surprises under the bed, shows that a hazardous mix of endocrine disrupting chemicals (EDCs) ...
Nuclear fission in the kitchen
04-08-2011
With an ambitious hobby project a Swedish man drew attention on himself: He wanted to build a nuclear reactor in his kitchen. "Not to gain electricity, just for fun and to see if it's possible to split atoms at home," as he writes in his blog about his project. The attempt to blend americium, ...
