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 ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...
