Abstract Dielectric ceramics with both excellent energy storage and optical transmittance have attracted much attention in recent years. However, the transparent Pb‐free energy‐storage were rare reported. In this work, we prepared relaxor ferroelectric (1 − x )Bi 0.5 Na TiO 3 – NaNbO (BNT– NN) by conventional solid‐state reaction method. We find NN‐doping can enhance polarization breakdown strength of BNT suppressing grain growth restrained reduction Ti 4+ to 3+ . As a result, high...
High-transition-temperature (high-T_c) superconductivity in cuprates has been discovered for more than three decades, but the underlying mechanism remains a mystery. Cuprates are only unconventional superconducting family that host bulk with T_cs above liquid nitrogen boiling temperature at 77 Kelvin. Here we report an observation of single crystals La3Ni2O7 maximum T_c 80 Kelvin pressures between 14.0-43.5 gigapascals using high-pressure resistance and mutual inductive magnetic...
Neodymium monoxide (NdO) is a metastable rare earth oxide material with unique electronic structure, which has potential applications across various fields such as semiconductors, energy, catalysis, laser technology, and advanced communications. Despite its promising attributes, the thermodynamic properties of NdO remain unexplored. In this study, high pressure, temperature phases neodymium (NdO, rocksalt structure) body-centered cubic (bcc) Nd metal were synthesized at 5 GPa 1473 K. X-ray...
Considering the sensitivity of rare microbial taxa to environmental disturbances and their critical roles in ecosystems, it is essential investigate how soil communities (particularly microbes) respond pesticide exposure. In this study, we found that thiazole pesticides significantly reduced severity potato common scab effectively disrupted pathogen's cell membrane integrity. Notably, hierarchical partitioning analysis indicated geocaulosphere constitute key clusters influencing disease...
A high performance digital demodulator for RFID reader receiver is proposed. After carefully analyzing the characteristics of received data, correlation operation introduced into to estimate frequency data and decode them. Simulation result indicates that this can work well under 6dB input signal-to-noise ratio (SNR) with +/- 22% deviation tolerance. FPGA implementation shows communication distance between tag be extended 5m above by use demodulator.
Abstract Rational design of technologically important exotic perovskites is hampered by the insufficient geometrical descriptors and costly extremely high-pressure synthesis, while big-data driven compositional identification precise prediction entangles full understanding possible polymorphs complicated multidimensional calculations chemical thermodynamic parameter space. Here we present a rapid systematic data-mining-driven approach to in high-throughput discovery speed A 2 BB ’O 6 family...

Nitrogen doped lutetium hydride has drawn global attention in the pursuit of room-temperature superconductivity near ambient pressure and temperature. However, variable synthesis techniques uncertainty surrounding nitrogen concentration have contributed to extensive debate within scientific community about this material its properties. We used a solid-state approach synthesize at high temperature (HPT) analyzed residual starting materials determine content. High oxide melt solution...
Li2GeTeO6 prepared at ambient pressure adopts the corundum derivative ordered ilmenite structure (rhombohedral R3). When heated 1073 K and 3–5 GPa, as-made can convert into a LiSbO3-derived Li2TiTeO6-type phase (orthorhombic Pnn2), which is third double A2BB′O6 in addition to Li2TiTeO6 Li2SnTeO6. This Pnn2 spontaneously reverts R3 if annealed up 1023 pressure. Although crystal structural analyses second harmonic generation measurements clearly demonstrate polar nature of both phases, P(E)...
Yttrium monoxide (YO) is a possible member of large family rare earth monoxides having the rock salt structure. It was predicted to be stable above 10 GPa and superconducting with higher critical temperatures at lower pressures. However, no syntheses bulk YO have been reported. Using first-principles calculations, we stability yttrium pressures 8.6 high temperature. Guided by these predictions, successfully synthesized in structure (Fm3̅m) 15 1600 °C. very metastable (both thermodynamically...
High-pressure solid-state synthesis advances boost discoveries of new materials and unusual phenomena but endures stringent recipe conditions, poor yield, high cost. A methodological approach for accelerated precisely high-pressure is therefore highly desired. Here, we take the exotic double-perovskite-related nonmagnetic Li2B+4B′+6O6 as an example to show pipeline data-mining, high-throughput calculations, experimental realization, chemical interception metastable phases. total 140...
A quadruple perovskite LaMn3Rh4O12 with A' = Mn and B 4d transition metal was synthesized at high pressure (8 GPa) temperature (1423 K) for the first time. Room powder X-ray diffraction indicates that forms in cubic symmetry (Im3̅, a 7.4997(1) Å). absorption near-edge spectroscopy shows predominantly Mn3+ Rh3+ oxidation states. An antiferromagnetic TN ∼ 41 K is corroborated by specific heat measurements. The resistivity measurements indicate three-dimensional Mott variable-range hopping...
