Summary: Metal nanoparticles, particularly palladium nanoparticles (Pd NPs), can be effectively controlled and stabilized by iptycene-containing poly(arylene ether)s (PAEs). The PAEs not only limit the growth of Pd NPs but also facilitate the efficient transport of analytes, making them excellent sensory materials for hydrogen gas detection under ambient conditions. Strategies such as presorting SWCNTs with pentiptycene-containing poly(p-phenylene ethynylene)s (PPEs) and thermal annealing further enhance the chemiresistive performance.

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.
