It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...
Researchers have built a levitation device to help them make precise measurements of chemical reactions (Anal. Chem. 2020, DOI: 10.1021/acs.analchem.0c00929). Levitating droplets on sound waves allows ...
