At the Niels Bohr Institute, University of Copenhagen, researchers have realized the swap of electron spins between distant quantum dots. The discovery is a step towards applications of quantum information, as the dots leave enough room for delicate control electrodes, enabling integration with traditional microelectronics and perhaps, a future quantum computer. The result is achieved via collaboration with Purdue University and the University of Sydney, Australia, now published in Nature Communications.

Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). This occurs at extremely high temperatures, but at relatively low energies. An international research team headed by Goethe University has now succeeded in investigating the capture of protons at the storage ring of the GSI Helmholtzzentrum für Schwerionenforschung.

Scientists have developed a pioneering new technique that could pave the way for the next generation of optical tweezers.

International research team developed a new method of synthesizing miniature light sources. It is based on a special laser producing millions of nanolasers from a perovskite film in a few minutes. Such lasers look like small disks, work at room temperature and have an tunable emission wavelength from 550 to 800 nm. The high speed and good reproducibility of this method make it promising for the industry. The study was published in ACS Nano.

Modern coal-fired power stations produce more ultrafine dust particles than road traffic and can even modify and redistribute rainfall patterns, a new 15-year international study shows. The study indicates filtration systems on modern coal-fired power stations are the biggest source of ultrafine particles and can have considerable impacts on climate in several ways.

In a new study, researchers at the University of Illinois at Urbana-Champaign have designed and demonstrated a novel type of polymer demonstrating a switchable thermal conductivity controlled by light. The material has the potential to route the conduction of heat on-demand and enable new, smarter, ways to manage heat.
