Plastic Waste Transformed into Soap: A Surprising Recycling Solution

Scientists at Virginia Tech have developed a method to upcycle polyethylene and polypropylene plastics into valuable surfactants used in soap and detergents. By heating the plastics and quickly cooling them, the long carbon chains in the plastics are broken down into short-chain polyethylene-like molecules. These molecules can then be further processed to produce fatty acids and ultimately soap. The upcycling method has the advantage of being able to work on both polyethylene and polypropylene simultaneously, eliminating the need for separate sorting. The process is cost-effective and environmentally friendly, offering a profitable alternative to traditional recycling methods.

Cracking the Mystery of Champagne Bubbles: Scientists Reveal the Secret

Researchers at Brown University and the University of Toulouse have discovered that the unique bubbles in Champagne are due to surfactants, which help reduce the tension between the liquid and gas bubbles, making for a smooth rise to the top. The straight-laced rise also enhances its taste. The research has economic and societal value, as understanding how bubbles cluster can help with technologies that use bubble-induced mixing, such as aeration tanks at water treatment facilities, and explain ocean seeps.

The Science Behind Champagne Bubbles' Straight Line Rise

Researchers have discovered why champagne bubbles rise in a straight line, unlike those of many other drinks. The unusual trait is down to particular ingredients in champagne that not only give it flavour but attach to the bubbles, changing the motion of the fluid immediately behind them as they rise and hence allowing the bubbles to form a chain. The straight lines of tiny bubbles within champagne are down to flavour molecules, such as fatty acids, within the drink that have surfactant properties.
