Scientists at Scripps Research have used rapid alternating current (AC) to selectively reduce carbonyl groups (J. Am. Chem. Soc. 2021, DOI: 10.1021/jacs.1c06572). The technique avoids side reactions ...
HIGH-FIELD superconductors can carry large currents distributed over their whole cross-section. These body currents are lossless when steady, exactly as are the surface currents of soft ...
