Levitating particles in a vacuum
Levitation of both large objects and of single atoms has become a widely used technique in science and engineering. In the last years, many researchers have started to explore a new horizon: the levitation of nano- and micro-particles—still smaller.....»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»

Observatory reveals key evidence of cosmic ray acceleration limit in W51 for first time
The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies.....»»
Nanoplastics put stress on trees and impair photosynthesis
It is well known that more and more plastic waste is ending up in soil and bodies of water. Researchers are particularly concerned about tiny micro- and nano-sized particles. It remains unclear how and to what extent they are able to enter living org.....»»
Exploring functional organic materials for the energy transition
Carbon, of all things, could help us to push forward the decarbonization of our industrial society. Functional carbon particles, known as carbon dots, can transform sunlight into energy and extract hydrogen from water. Prof. Dr. Dirk M. Guldi, a chem.....»»

Using machine learning to speed up simulations of irregularly shaped particles
Simulating particles is a relatively simple task when those particles are spherical. In the real world, however, most particles are not perfect spheres, but take on irregular and varying shapes and sizes. Simulating these particles becomes a much mor.....»»
Heaviest antimatter observation yet will fine-tune numbers for dark matter search
In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic antimatter particles......»»
Ultra-sensitive photothermal microscopy technique detects single nanoparticles as small as 5 nm
The detection of individual particles and molecules has opened new horizons in analytical chemistry, cellular imaging, nanomaterials, and biomedical diagnostics. Traditional single-molecule detection methods rely heavily on fluorescence techniques, w.....»»
Could we ever harness quantum vacuum energy?
The fabric of spacetime is roiling with vibrating quantum fields, known as vacuum energy. It's right there, everywhere we look. But could we ever get anything out of it?.....»»
Breaking boundaries: The unexpected routes of minerals in crop growth
Imagine plants not just sipping nutrients dissolved in water, but actually munching on tiny mineral particles straight from the soil. A study sheds light on how wheat and lettuce aren't just passive feeders—they actively grab, transport, and utiliz.....»»
