Researchers at Oxford have pioneered an innovative new method for producing fluorochemicals sustainably without hazardous HF gas. Their nature-inspired technique activates calcium fluoride via mechanochemistry, mimicking the process that forms our bones and teeth. This creates “fluoromix” which can synthesize over 50 useful fluorochemicals at high yields up to 98%, eliminating the need for toxic HF production. Published in Science, this breakthrough could revolutionize fluorochemical manufacturing globally by enabling dramatically safer and greener chemistry.
New research upends long-held ideas about brachiopods and bivalves after the devastating Permian mass extinction. Computational analysis shows both groups declined together, rebounded, and were responding to shared environmental factors – not direct competition. Bivalves adapted better to post-extinction oceans, leading to brachiopod retreat, but didn’t actively displace them as once thought. The study provides fresh perspective on how life rebuilt after the catastrophic end-Permian crisis.
Cornell University’s groundbreaking research has unveiled a paradigm shift in our understanding of volcanic eruptions, suggesting that carbon dioxide from deep within the Earth, rather than water, drives the activity of certain volcanoes. This revelation underscores the complexity of our planet’s internal dynamics and has significant implications for volcanic hazard preparedness.
