Summary: This study proposes a novel inductively coupled plasma (ICP) system consisting of a segmented dielectric window and a metal frame. The thin window design compensates for power loss caused by the metal frame, enhancing the controllability of the gas flow field and reducing capacitive power coupling. Three-dimensional fluid self-consistent plasma simulations and experiments confirm the superior uniformity and reliability of the proposed ICP system for semiconductor processes, comparable to conventional ICP systems used in etching and deposition.

Summary: EAFD is a major source of recyclable zinc, with the co-pyrolysis of EAFD with halogen-containing polymers being a potent approach for selective zinc extraction. The construction of a microkinetic model to account for the surface halogenation of zinc ions in franklinite into zinc halides is crucial for optimizing this process effectively. The model accurately illustrates the chemical phenomena involved in the mass loss curves in EAFD-PVC/BFRs formulations, providing valuable insights into the extraction of zinc from EAFD.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
