Light emitting transistor using carbon nanotubes

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University (Germany) and the University of St Andrews (Scotland) used light-emitting and extremely stable transistors to reach strong light-matter coupling and create exciton-polaritons. These particles may pave the way for new light sources, so-called …

Major contributor of air pollution is removed by concrete surfaces

New research reveals that sulfur dioxide, a major contributor to air pollution, is removed from the air by concrete surfaces. Stony Brook University researcher Alex Orlov, PhD, and colleagues discovered how concrete interacts and eliminates sulfur and nitrogen oxides. Their findings, published in the July edition of the Journal of Chemical …
