The Seebeck effect describes the generation of an electric potential in a conducting solid exposed to temperature gradient. Besides fundamental relevance state physics, it serves as key quantity determine performance functional thermoelectric materials. In most cases, is dominated by energy-dependent electronic density states at Fermi level, line with prevalent efforts toward superior thermoelectrics through engineering structure. Here, we demonstrate alternative source for based on...
Neutrons spot magnetic fluctuations that propel charges in a novel class of paramagnetic thermoelectrics.
Thermoelectric devices can directly convert thermal energy to electricity or vice versa with the efficiency being determined by materials’ dimensionless figure of merit ( ZT ). Since revival interests in last decades, substantial achievements have been reached search high‐performance thermoelectric materials, especially high temperature regime. In near‐room‐temperature regime, MgAgSb‐based materials are recently obtained ≈ 0.9 at 300 K and ≈1.4 525 K, as well a record conversion 8.5%....
Electric polarization in conventional paraelectric/ferroelectric oxides usually involves the displacement of nonmagnetic transition-metal ions with an empty $d$ shell. Here we unravel unusual mechanism for electric based on magnetic ${\mathrm{Fe}}^{3+}$ $(3{d}^{5})$ ions. Our simulations suggest that competition between long-range Coulomb interaction and short-range Pauli repulsion a $\mathrm{Fe}{\mathrm{O}}_{5}$ bipyramidal unit proper lattice parameters would favor off-center...
Magnetic Weyl semimetals (MWSMs) have attracted significant attention due to their intriguing physical properties and potential applications in spin-electronic devices. Here we report the characterization of NdAlSi including transport, magnetization, heat capacity on single crystals, as well band structure calculation. It is a newly proposed MWSM candidate which breaks both time-reversal spatial inversion symmetries. A temperature--magnetic field phase diagram experimentally established....
This study aims to understand the influence of chlorophyll fluorescence parameters on yield winter wheat in some areas China. Nitrogen (N) application is believed improve photosynthesis flag leaf, which ultimately increases final yield. The experiment was conducted experimental base Shanxi Agricultural University Taigu, Province, China; before sowing, four N rates were set—N0, N120, N150, and N210 kg ha–1 Yunhan-20410 variety from 2019 2022. results different research showed that organic...

We report a comprehensive investigation of the structural, magnetic, transport and thermodynamic properties single crystal PrAlSi, in comparison to its nonmagnetic analogue LaAlSi. PrAlSi exhibits ferromagnetic transition at $T_C$ = 17.8 K which, however, is followed by two weak phase transitions lower temperatures. Based on combined dc ac magnetic susceptibility measurements, we propose reentrant phases below be spin glasses or cluster glasses. When glassy states are suppressed small field,...
By integrating fiber-reinforced composites (FRCs) with Three-dimensional (3D) printing, the flexibility of lightweight structures was promoted while eliminating mold’s limitations.
