Trapping particles to explain lightning
Using lasers as tweezers to understand cloud electrification might sound like science fiction but at the Institute of Science and Technology Austria (ISTA) it is a reality. By trapping and charging micron-sized particles with lasers, researchers can now observe their charging and discharging dynamics over time. This method, published in Physical Review Letters, could provide key insights into what sparks lightning.
Aerosols are liquid or solid particles that float in the air. They are all around us. Some are large and visible, such ...
