DFT Study of Metal (Ag, Au, Pt)-Modified SnS₂ for Adsorption of SF₆ Decomposition Gases in Gas-Insulated Switchgear

Langmuir, Год журнала: 2024, Номер 40(13), С. 7049 - 7059

Опубликована: Март 23, 2024

In this study, the gas-sensitive response of metal (Ag, Au, Pt)-modified SnS2 toward SF6 decomposition gases (SOF2, SO2F2, SO2, H2S) in gas-insulated switchgear was studied by analyzing adsorption structure, band charge transfer, and density states based on functional theory. The results show that four target pristine belongs to weak physical adsorption. Compared with SnS2, energy transition atom-modified monolayer has been improved a certain extent capacity these obviously improved. Moreover, recovery time Ag-SnS2/SOF2, Ag-SnS2/SO2F2, Au-SnS2/SOF2, Au-SnS2/SO2F2, Pt-SnS2/SO2F2 is too short, indicating conditions have poor sensitivity are not suitable as detection materials for gases. According different changes conductivity during adsorption, it provides feasible solution detect each gas. This theoretical study effectively explained sensing properties between metal-modified monolayers

Crumpled Nanogenerator Based on Elastic Modulus Design for Fully Self-Powered High-Speed Rail Speed Measurement

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(13), С. 15478 - 15487

Опубликована: Июнь 24, 2024

Self-powered sensors are an important application development direction of nanogenerators. The fully self-powered systems that do not rely on traditional energy such as mains power or batteries is great value to the future design loT. Such system easy task due detailed calculation multiple units' consumption combined with smart minimizing total full design. By converting wind into electrical and designing indication simultaneously utilizes this energy, we completed a sensing transduce strength high-speed rail. sensor part modulus pleated elastomer at same time achieves pressure-LED indication. circuit simplified by dropping control chips, decreasing consumption, increasing reliability. This crumple has faster activation speed than other cup can sense force when train passes protect canopy structure. presents ideas for designs systems.

Accelerated Screening of Highly Sensitive Gas Sensor Materials for Greenhouse Gases Based on DFT and Machine Learning Methods

ACS Sensors, Год журнала: 2025, Номер 10(1), С. 563 - 572

Опубликована: Янв. 6, 2025

Greenhouse gases (GHGs) have caused great harm to the ecological environment, so it is necessary screen gas sensor materials for detecting GHGs. In this study, we propose an ideal design strategy with high screening efficiency and low cost targeting four typical GHGs (CO2, CH4, N2O, SF6). This introduces machine learning (ML) methods based on density functional theory (DFT) achieve accurate rapid from a large number of candidate materials. Specifically, include 28 different transition metal-doped WSe2 monolayers (TM-WSe2), molecules their optimal adsorption structures TM-WSe2 are constructed. Ten fine-tuned ML models implemented train predict energy (Eads) distance (D) target TM-WSe2, thereby selecting model identifying these promising addition, gas-sensing properties verified by band structure, work function, recovery time. research provides reasonable low-cost new way help artificial intelligence proves its effectiveness through experiments.
