Light and Heat Team Up to Turn CO₂ into Valuable Chemicals

Scientists have developed a breakthrough method that uses the combined power of infrared light and heat to convert carbon dioxide into a useful chemical with 100% selectivity. This dual-energy approach, powered by a specially engineered cerium oxide catalyst, overcomes the performance bottlenecks that have plagued traditional heat-only conversion processes.

Scientists Forge a Robust 2D Catalyst for Greener Chemical Synthesis

Chemists have developed an exceptionally robust, two-dimensional material that acts as a powerful catalyst. This new structure, called IITKGP-54, withstands harsh chemical conditions and efficiently orchestrates the synthesis of medically important compounds using environmentally friendly methods. Its reusability and effectiveness in water mark a significant step forward for sustainable chemistry.

Ocean 'Amplifier' Speeds Up Acidification on US West Coast

Researchers studying the California Current System have discovered that its waters are acidifying at an amplified rate, outpacing the increase in atmospheric CO2. By analysing orange cup corals and using computer modelling, they found this acceleration is driven by an interaction between human-caused CO2 and the ocean's natural processes. This trend is expected to continue, posing a significant threat to the region's vital marine ecosystems.
