Experimental methods in chemical engineering: Magnetometry

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Magnetometry is a non‐invasive technique to characterize the behaviour of magnetic materials of which the most common contain Fe, Co, and Ni. Vibrating sample magnetometers (VSMs) vibrate samples at a fixed frequency in a static, homogeneous magnetic field to induce a voltage in pick up coils according to Faraday's law of induction.

A 40.68‐MHz Active Rectifier Using PLL and PWM Control of DC‐DC Converter for ON/OFF Delay Compensation

International Journal of Circuit Theory and Applications, EarlyView.
A ramp‐based phase‐locked loop (RPLL) active rectifier operating at 40.68 MHz compensates switching delay variations to improve phase alignment. The proposed architecture achieves 90.3% peak power conversion efficiency and 98.0% voltage conversion ratio for high‐frequency wireless power transfer in implantable medical devices.
