Runaway electron-induced plasma facing component damage in tokamaks
This Roadmap article addresses the critical and multifaceted challenge of plasma-facing component (PFC) damage caused by runaway electrons (REs) in tokamaks, a phenomenon that poses a significant threat to the viability and longevity of future fusion reactors such as ITER and DEMO. The dramatically increased RE production expected in future high-current tokamaks makes it difficult to avoid or mitigate REs when a plasma discharge terminates abnormally. Preventing damage from the intense localise…

The Onset of Metastable Turbulence in Pipe Flow
The onset of turbulence in pipe flow has been a fundamental challenge in physics, applied mathematics, and engineering for over 140 years. To date, the precursor of this laminar-turbulent transition is recognized as transient turbulent spots or puffs, but their defining characteristics - longevity, abrupt relaminarization, and super-exponential lifetime scaling - have been lack of first-principles explanations. By combining extensive computer simulations, theory, and verifications with experime…

Composite material keeps solar panels cool, boosting longevity by more than 200%
A team of international researchers led by King Abdullah University of Science and Technology (KAUST) in Saudi Arabia has developed a new composite material made of acrylate that enhances the performance of solar cells. Adhering the composite material to solar cells deployed in Saudi Arabia for weeks significantly raised the power output and longevity while reducing the electricity consumed by the cells. The study can be read in Materials Science and Engineering: R: Reports.
