Summary: Recently, a composite thermoelectric material consisting of conducting polymer (PEDOT:PSS) and nanostructured tellurium (Te) has been developed, which exhibits high thermoelectric performance along with mechanical flexibility. However, its vulnerability to oxidation limits its ability to harvest energy continuously in various environments. To address this issue, a Se doping strategy is proposed in this report to enhance the oxidation stability of the composite material and evaluate its characteristics and thermoelectric properties. The Se-doped nanostructured Te/PEDOT:PSS composite material demonstrates improved oxidation stability and thermoelectric properties, making it a promising candidate for future thermoelectric device applications.

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.
