Carbyne – an unusual form of carbon

International team of researchers investigates optical band gap of carbon compound

13-Nov-2020

Which photophysical properties does carbyne have? This was the subject of research carried out by scientists at FAU, the University of Alberta, Canada, and the Ecole Polytechnique Fédérale de Lausanne in Switzerland, which has led to a greater understanding of the properties of this unusual form ...

The Secret Contamination of Polar Bears

Hundreds of unrecognized halogenated contaminants discovered in polar bear serum

05-Dec-2018

Using a new approach to measure chemical contaminants in polar bears, scientists from Canada and the United States found a large variety of new chlorinated and fluorinated substances, including many new polychlorinated biphenyl metabolites. Worryingly, these previously unrecognized contaminants ...

This is your brain. This is your brain outdoors

The brain acts much differently when we're outdoors

31-Jan-2018

The brain acts much differently when we're outdoors compared to when we're inside the lab, a new study has found. "It happens when we're doing normal, everyday activities, like riding a bike," explained Kyle Mathewson, a neuroscientist in UAlberta's Department of Psychology. Mathewson and his ...

New window into the nanoworld

22-Feb-2017

For the first time ever, scientists have captured images of terahertz electron dynamics of a semiconductor surface on the atomic scale. The successful experiment indicates a bright future for the new and quickly growing sub-field called terahertz scanning tunneling microscopy (THz-STM), pioneered ...
