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...

Engineers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a small monitoring device, worn on the skin, that detects alcohol levels in perspiration. It was designed as a convenient method for individuals to monitor alcohol intake, which could help reduce unsafe drinking that can lead to vehicle crashes, violence, and the degeneration of health.
Seila Selimovic, Ph.D., director of the NIBIB Program in Tissue Chips, explains the new technology...

Assistant Professor Arkadiy Lyakh of UCF’s NanoScience Technology Center has developed the most efficient Quantum Cascade Laser ever.
A team of UCF researchers has produced the most efficient quantum cascade laser ever designed – and done it in a way that makes the lasers easier to manufacture. Quantum cascade lasers, or QCLs, are tiny – smaller than a grain of rice – but they pack a punch. Compared to traditional lasers, QCLs offer higher power output and can be tuned to a wide range of infrared wavelengths. They can also be used at room temperature without the need for bulky cooling systems.
But because they’re difficult and costly to produce, QCLs aren’t used much outside the Department of Defense...
