The diverse array of sensors deployed on meteorological observation towers, tasked with the gradients, requires distinct power supplies and effective regulation. In this article, a multi-frequency, multi-receiver (MFMR) inductively coupled transfer (ICPT) system using time-sharing frequency strategy is proposed, which enables to multiple nodes through only one cable. control (TSFC) method introduced produce multi-frequency currents. By incorporating controllable resonant capacitor at...

Abstract In light of the current situation where utilization calcium carbide slag yields low profits but holds significant potential for reducing carbon emissions, ammonium acetate was employed to leach slag. It also played a crucial role in regulating products indirect dioxide carbonation when mixed with glycine and lye. Ammonium acetate's significance underscores its dual both leaching processes. This process yielded carbonate particle sizes smaller than 100 nm, purity 98% single vaterite...
Switched-capacitor converters (SCCs) have been developed for decades and applied successfully in many applications due to the merits of high-power density, high efficiency, low cost.

We report on rapid thermogravimetric analysis (TGA) using MEMS resonant cantilevers at a heating rate exceeding 200°C/min (the limit of state-of-the-art furnace-based conventional TGA instruments). Each cantilever integrates resonance excitation/excitation resistors for mass sensing and microheater sample heating. By leveraging the miniature device size, unique thermal isolation structure design, we achieve temperature-programmed in loading region up to 1000°C/min. then perform measurements...
