Study reveals clues to cause of hydrogen embrittlement in metals

November 20, 2012 – 9:04 am

Study reveals clues to cause of hydrogen embrittlement in metals - Hydrogen can easily dissolve and migrate within metals to make these otherwise ductile materials brittle and more prone to failures. Now, researchers at McGill University in Montreal and Ecole Polytechnique Federale de Lausanne in Switzerland, have shown that the physics of hydrogen embrittlement may be rooted in how hydrogen modifies material behaviors at the nanoscale. In a study published in Nature Materials, they present a model that can accurately predict the occurrence of hydrogen embrittlement. http://www.mcgill.ca/channels/news/study-reveals-clues-cause-hydrogen-embrittlement-219051

Mercury in Water, Fish Detected with Nanotechnology

September 13, 2012 – 10:00 am

Mercury in Water, Fish Detected with Nanotechnology - When mercury is dumped into rivers and lakes, the toxic heavy metal can end up in the fish we eat and the water we drink. To help protect consumers from the diseases and conditions associated with mercury, researchers at Northwestern University in collaboration with colleagues at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, have developed a nanoparticle system that is sensitive enough to detect even the smallest levels of heavy metals in our water and fish.(10.1038/nmat3406)
