A new technique enables the use of fatty acids—for example, those found in cooking oil from fast-food restaurants—to dissolve and separate silver. The process requires light and diluted hydrogen ...

New research shows that magnesium and other metals in mine waste can be solubilized and recovered thanks to acid-producing bacteria. Researcher Nathan van Wyk believes that the method has great ...

image: Acids are reactive, with even weak acids like vinegar interacting with other materials to wow students. But strong acids can really put on a show. For example, aqua regia, or royal water, is a ...

Scientists have developed a cleaner way to separate cobalt and nickel from lithium-ion battery materials using an electrochemical technique boosted by a naturally occurring acid commonly associated ...

In a recent study published in the Chemical Engineering Journal, researchers from the Universities of Helsinki and Jyväskylä developed a novel method that allows for the utilization of substances such ...

A spent electric vehicle battery pack is, by most accounts, a recycling headache. Cracking one open means dealing with toxic electrolytes, mixed metal oxides, and a chemistry puzzle that the industry ...
