Abstract Developing thermoelectric (TE) performance is impeded by the compromise of TE parameters, resulting in inadequate conversion efficiency heat to electricity. Herein, this work reports that Mo a particularly effective additive Mg 3 Sb 2 ‐based alloys with significantly improved electronic transport via grain‐boundary engineering and band‐structure regulation synergy. In addition, phonon simultaneously suppressed employing multiple effects, lattice imperfection scattering, reduced...
Abstract Thermoelectric cooling materials based on Bi 2 Te 3 have a long history of unsurpassed performance near room temperature. Recently, research into price‐competitive Mg (Bi, Sb) ‐based are focused replacing traditional materials. Here, the thermoelectric properties 3.2 1.998−x Sb x 0.002 Cu 0.005 (x = 0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) polycrystalline compounds investigated. In all temperature regions, electrical resistivity Seebeck coefficient increased with concentration. The...
A kind of low-temperature thermoelectric material is discovered in quenched GeTe-based alloys with high performance superior to Bi<sub>2</sub>Te<sub>3</sub>-based alloys.
A global softening strategy using stearic acid in MgAgSb to reduce sound velocity has been shown enhance its thermoelectric performance, achieving high zT values and demonstrating strong potential for low-grade heat harvesting.
Ensuring long-term reliable contacts in thermoelectric devices is particularly challenging due to their operation under high temperatures and has been one of the large obstacles field for application. Typically, thermodynamically driven atomic diffusion reactions often degrade contacts, leading increased contact resistivity ultimately limiting device's lifespan. Here, we report an unconventional self-optimized mechanism Sb/MgAgSb junction. Mg from MgAgSb Sb does not but instead optimizes its...

We investigated the acidity and concentrations of water-soluble ions in PM2.5 aerosol samples collected from an urban site Beijing a rural Gucheng, Hebei Province November 2016 to January 2017 gain insight into formation secondary inorganic species. The average SO42–, NO3–, NH4+ were 8.3, 12.5, 14.1 μg m–3, respectively, at 14.0, 14.2, 24.2 site. nitrogen sulfur oxidation ratios correlated with relative humidity (with correlation coefficient r = 0.79 0.67, respectively) loadings. Based on...
Discovery and engineering of novel phase structures pave new avenues in the study phonon-electron decoupling thermoelectric materials, with final aim enhancing their figure merit ZT. Here, we report a metastable GeTe that shows coexisting cubic rhombohedral phases enhances ZT GeTe-based alloys to ∼0.8 at 300 K ∼1.3 373 K. This is comparable state-of-the-art Bi2Te3-based low-temperature range. The enhancement positive correlation an increased contribution special synergetic specific...
ABSTRACT Poly(9,9‐di‐ n ‐octylfluorene‐ alt ‐benzothiadiazole (F8BT) generally has a large Seebeck coefficient, and single‐walled carbon nanotubes (SWCNTs) have high electrical conductivity. In this work, we prepared F8BT/SWCNT composites to combine the good coefficient of polymer excellent conductivity SWCNTs achieve enhanced thermoelectric properties. For composite materials, maximum power factor 1 μW mK −2 was achieved when SWCNT content 60%, with ZT value 4.6 × 10 −4 . After ferric...
Since the CLAW hypothesis was proposed approximately three decades ago, aerosols derived from dimethylsulfide (DMS) conversion have been intensively investigated. In this study, long-term observations were conducted for methanesulfonic acid (MSA), oxidation product of DMS, 2008 to 2016 in marine boundary layer Bering Sea. We found that (1) increase sea surface temperatures led increased DMS emissions and MSA concentrations; however, (2) air masses different sources caused significant...
