• Australian researchers use a quantum computer to simulate how real molecules behave

  17 mai
  When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths of a billionth of a second.

• Theoretical model provides fresh route to more efficient cooling using light and heat

  16 mai
  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 (…)

• From landslides to pharmaceuticals : High-precision model simulates complex granular and fluid interactions

  16 mai
  A research team from the School of Engineering at the Hong Kong University of Science and Technology has developed a new computational model to study the movement of granular materials such as soils, sands and powders. By integrating the dynamic interactions among particles, air and water (…)

• Scientists observe collective behavior of femtoscopic droplets at CERN

  16 mai
  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 (…)

• An ’invisible order’ in glass shapes vibrations in the terahertz frequency range

  16 mai
  Although glasses exhibit disordered atomic structures, X-ray and neutron scattering reveal a subtle periodicity. Researchers at the University of Tsukuba have demonstrated that this hidden periodicity—referred to as "invisible order"—plays a critical role in determining vibrational (…)
