As climate change and growing energy demands strain global systems, scientists are increasingly turning to passive cooling technologies—ways to cool objects or spaces without using electricity. One promising method is radiative cooling, which works by reflecting sunlight and releasing heat in the form of infrared radiation into space. But despite its potential, this method is […]

Whether diving off docks, cannonballing into lakes or leaping off the high board, there’s nothing quite like the joy of jumping into water.

At CERN’s Large Hadron Collider (LHC), lead atom nuclei, accelerated in opposite directions, collide at speeds close to the speed of light. In such scattering processes, the quarks and gluons that make up these nuclei collide, creating other quarks and gluons, produced by the fundamental interaction known as the “strong interaction.” The number of particles […]

A surprising effect was discovered through a collaborative study by researchers from TU Wien and institutions in Croatia, France, Poland, Singapore, Switzerland, and the US during the investigation of a special material: the atoms are arranged in a completely disordered manner but produce magnetic order.

Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many technologies that affect our daily lives, including energy harvesting with solar cells, light-emitting-diode (LED) displays and telecommunications through fiber optic networks.

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the hypothetical force shaping the universe sprang from particles that rapidly condensed, like steam into water.

Scientists have developed a dual-laser Brillouin optical correlation-domain reflectometry (BOCDR) system that uses two frequency-modulated lasers. By scanning the relative modulation phase between the pump and reference lasers, the setup measures strain and temperature all along an optical fiber. In a proof-of-concept test on a 13-meter silica fiber, the team recorded Brillouin gain spectra (BGS) […]

By breaking away from the laws of classical physics, quantum physics has opened the door to describing the behavior of atoms and particles. This science, which explores the most fundamental building blocks of nature, relies in particular on the ability to measure their individual and collective properties.
