Electron spin. Spin, an intrinsic property of electrons, is related to the dynamics of electrons excited as a result of singlet fission – a process which could be used to extract energy in future solar cell technologies. Credit: Image provided by Leah Weiss
Physicists have successfully employed a powerful technique for studying electrons generated through singlet fission, a process which it is believed will be key to more efficient solar energy production in years to come. Their approach, reported in the journal Nature Physics, employed lasers, microwave radiation and magnetic fields to analyse the spin of excitons, which are energetically excited particles formed in molecular systems.
These are generated as a result of singlet fission, a process that researchers around the world are try...

Droplets in space can grow freakishly large and bounce off nonwetting surfaces in truly unearthly ways. Astronauts frequently encounter huge droplets, and Scott Kelly recently demonstrated their unusual behavior aboard the International Space Station (ISS) via water balls and a hydrophobic ping pong paddle. To explore the dynamics of these gigantic droplets, a group of researchers led by Mark Weislogel, a professor within the Department of Mechanical & Materials Engineering at Portland State University in Oregon, is generating and studying them right here on Earth.
How, you ask? They simply form a puddle on a flat nonwetting surface and drop it 6 stories in a “tower drop...
