Instead of burning fossil fuels to smelt steel and cook cement, researchers in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000 C (1,832 F), demonstrating the method's potential role in providing clean energy for carbon-intensive industries.

A team of scientists has developed a novel technique to convert carbon dioxide (CO2) from treated flue gas directly into high-value chemicals and fuels. This innovation sidesteps the conventional approach of using high-purity CO2 for electrochemical reduction processes, achieving significant cost savings of about 30%.

Polystyrene is made from styrene building blocks and is the most widely used plastic in terms of volume, for example in packaging. Unlike PET, which can now be produced and recycled using biotechnological methods, the production of polystyrene has so far been a purely chemical process. The plastic can't be broken down by biotechnological means, either. Researchers are looking for ways to rectify this: An international team decoded a bacterial enzyme that plays a key role in styrene degradation. This paves the way for biotechnological application.

A method has been discovered to treat water heavily contaminated with unhealthful forever chemicals, known by chemists as PFAS or poly- and per-fluoroalkyl substances. It involves treating heavily contaminated water with ultraviolet (UV) light, sulfite, and a process called electrochemical oxidation. It breaks up strong fluorine-to-carbon bonds in the PFAS compounds and other concentrated organic compounds in heavily polluted water. The reaction also occurs at room temperature without a need for additional heat or high pressure. This method is expected to be useful in cleanups of PFAS pollution from decades of fire suppressant foam use at military facilities.

Move over, graphene. There's a new, improved two-dimensional material in the lab. Borophene, the atomically thin version of boron first synthesized in 2015, is more conductive, thinner, lighter, stronger and more flexible than graphene, the 2D version of carbon. Now, researchers have made the material potentially more useful by imparting chirality -- or handedness -- on it, which could make for advanced sensors and implantable medical devices.
