Scientists Convert Plastic Waste Into Fuel Using Heated Salts

Researchers at Oak Ridge National Laboratory have developed a molten-salt process that converts common polyethylene waste into gasoline- and diesel-like fuels at temperatures below 200 degrees Celsius, according to a study published in the Journal of the American Chemical Society. The method bypasses the extreme heat and expensive precious-metal catalysts typically required to break down … Read more

Injectable Microgel System Delivers Precise Radiation to Keloids

Injectable hyaluronic acid microgels carrying radioactive iodine-131 offer a precise, minimally invasive method to deliver localized radiation therapy to keloid scars, according to a preclinical study published by researchers at Pusan National University. The strategy aims to overcome the targeting limitations of conventional external-beam radiation when treating small, irregular skin lesions. The Keloid Treatment Challenge … Read more
