Researchers have synthesized a new compound, which forms a so-called covalent organic framework. The compound, which is based on condensed phosphonic acids, is stable and can for example be used to capture carbon dioxide. An international research team headed by Heinrich Heine University Düsseldorf (HHU) and the University of Siegen has synthesised a new compound

Researchers have developed a solid electrolyte that could be a suitable material for all-solid-state batteries. Solid electrolyte composed of nanoparticles embedded in an amorphous matrix shows high conductivity, formability, and electrochemical stability. Often overlooked, rechargeable batteries play an important part in contemporary life, powering small devices like smartphones to larger ones like electric vehicles. The

Spider silk, long prized for its strength and elasticity, has created something of a furor in the biomanufacturing world as businesses look for ways to cheaply scale up production for silks, which can be used in everything from tactical gear to sutures and textiles. However, a comprehensive study shows that there are many challenges facing

Engineers found a novel path around tedious process of tunneling individual sub-nanometer pores for nanoporous membranes one by one. The team created a new method of pore generation that builds materials with intentional weak spots, then applies a remote electric field to generate multiple nano-scale pores all at once. Nanoporous membranes with atomic-scale holes smaller

Amethyst is a violet variety of quartz which has been used as a gemstone for many centuries and is a key economic resource in northern Uruguay. Geodes are hollow rock formations often with quartz crystals, such as amethyst, inside. Amethyst geodes in Uruguay have been found in cooled lava flows, which date from the original

Are there planets beyond Earth where humans can live? The answer is maybe, according to physicists examining F-type star systems. Are there planets beyond Earth where humans can live? The answer is maybe, according to a new study from University of Texas at Arlington physicists examining F-type star systems. Stars fall into seven lettered categories

Discerning whether a nuclear reactor is being used to also create material for nuclear weapons is difficult, but capturing and analyzing antimatter particles has shown promise for monitoring what specific nuclear reactor operations are occurring, even from hundreds of miles away. Researchers have developed a detector that exploits Cherenkov radiation, sensing antineutrinos and characterizing their

Everyday experience tells us that light reflected from a perfectly flat mirror will give us the correct image without any deformation. Interestingly, this is not the case when the light field itself is structured in a complex way. Tiny deformations appear. These have now been observed in the laboratory. The results confirm the prediction of

Astronomers have detected carbon dioxide and hydrogen peroxide on the frozen surface of Pluto's largest moon, Charon, using observations from the James Webb Space Telescope. These discoveries add to Charon's known chemical inventory, previously identified by ground- and space-based observations, that includes water ice, ammonia-bearing species and the organic materials responsible for Charon's gray and

Astronomers have discovered an exoplanet orbiting Barnard's star, the closest single star to our Sun. On this newly discovered exoplanet, which has at least half the mass of Venus, a year lasts just over three Earth days. The team's observations also hint at the existence of three more exoplanet candidates, in various orbits around the
