Co3O4/Co2MnO4 nanocomposites, derived from a single-source CoMn-layered double hydroxide precursor, exhibit excellent bifunctional oxygen electrode activities for both reduction and evolution reactions, which can be attributed to the large specific surface area well-dispersed heterogeneous structure of nanocomposites.
In recent years, significant advances have been achieved in the red and green perovskite quantum dot (PQD)-based light-emitting diodes (LEDs). However, performances of blue LEDs are still seriously lagging behind that counterparts. Herein, we successfully developed Ni2+ ion-doped CsPbClxBr3-x PQDs through room-temperature supersaturated recrystallization synthetic approach. We simultaneously realized doping various concentrations cations modulated Cl/Br element ratios by introducing...
We present the superconducting (SC) property and high-robustness of structural stability kagome CsV 3 Sb 5 under in situ high pressures. For initial SC-I phase, its T c is quickly enhanced from 3.5 K to 7.6 then totally suppressed at P ∼ 10 GPa. With further increasing pressure, an SC-II phase emerges 15 GPa persists up 100 The rapidly increases maximal value 5.2 = 53.6 slowly decreases 4.7 A two-dome-like variation concluded here. Raman measurements demonstrate that weakening E 2g mode...
Abstract Metallic MoS 2 (i.e., 1T‐MoS ) is considered as the most promising precious‐metal‐free electrocatalyst with outstanding hydrogen evolution reaction (HER) performance in acidic media comparable to Pt. However, sluggish kinematics of HER alkaline and its inability for oxygen (OER), hamper development bifunctional catalysts. The instability further impedes applications scaling up, calling an urgent need simple synthesis produce stable . In this work, challenge first addressed using a...
Abstract The exploration of promising nonlinear optical materials, which allows for the construction high-performance devices in fundamental and industrial applications, has become one fastest-evolving research interests recent decades plays a key role development innovation optics future. Here, by utilizing nonlinearity recently synthesized, two dimensional material AuTe 2 Se 4/3 prepared self-flux method, passively mode-locked fiber laser operating at 1557.53 nm is achieved with 147.7 fs...
A highly active bifunctional electrocatalyst for oxygen reduction and evolution reactions was developed based on nanocarbon-intercalated Fe–N-codoped graphene materials.
The recently emerged van der Waals ferromagnet Fe3GaTe2 has an above-room-temperature TC of ∼350 K. By measuring the magneto-optical Kerr effect microscopy and Lorentz transmission electron on high quality crystals at room temperature, we visualized that magnetic field applied perpendicularly to (001) plane bulk crystal below can turn ground-state labyrinth-stripe domain into Néel-type skyrmions. result is also supported by measured topological Hall effect. Furthermore, identified reduction...
Halide double perovskites A2B(I)B(III)X6, in which monovalent B(I) and trivalent B(III) cations are arranged the B-sites of perovskite structure with a rock-salt ordering, have attracted substantial interest field optoelectronics. However, ordering generally leads to low electronic dimensionality, relatively large bandgaps carrier effective masses. In this work, we demonstrate, by density functional theory (DFT) calculations, that dimensionality thus properties halide can be effectively...
We demonstrated an ultra-low-noise polarization-maintaining (PM) single-frequency fiber laser at 2 µm. Both relative intensity noise (RIN) and frequency were improved by suppressing the pump source RIN using feedback control. After a two-stage Tm3+-doped PM amplifier, output power reached about 5 W, amplifier did not introduce any observable extra noise. The was less than 100Hz/Hz above 13 Hz, which is comparable to of typical seed Advanced LIGO high-power laser. central wavelength measured...
Exploration of exotic phenomena in magnetic topological systems is at the frontier condensed matter physics, holding a significant promise for applications spintronics. However, complex structures carrying nontrivial properties hinder its progresses. Here, we investigate pressure effect on novel kagome magnets GdV 6 Sn and TbV to dig out interplay between Gd/Tb layers nonmagnetic V-based sublattice. The pressure-tuned transition temperature T m both compounds exhibit turning point critical P...
Analyses of diatoms, grain size, magnetic susceptibility, total organic carbon, and nitrogen were applied to a 9.26 m long sediment core, spanning the last 12.2 kyr, from small treeline lake (Tiancai Lake, ~3898 a.s.l.) in southwest China. Diatom assemblages are dominated by Cyclotella distinguenda, Aulacoseira species, fragilarioid taxa, all which sensitive changes water pH light conditions that probably related vegetation development runoff processes triggered variations Asian monsoon....
Evaluating tumor development is of great importance for clinic treatment and therapy. It has been known that the amounts sialic acids on cell membrane surface are closely associated with degree cancerization cell. So, in this work, cellular interface supported CRISPR/Cas trans-cleavage explored electrochemical simultaneous detection two types acids, i.e., N-glycolylneuraminic acid (Neu5Gc) N-acetylneuraminic (Neu5Ac). Specifically, PbS quantum dot-labeled DNA modified by Neu5Gc antibody...
CAFs secrete VEGFA in the tumor microenvironment to induce angiogenesis and promote growth. The downregulation of secretion from helps block exerts an anti-tumor effect. In vivo experiments showed that tumor-bearing mice ligustilide group was significantly reduced. results MTT, tube formation, Transwell scratch did not affect proliferation HUVECs a certain concentration range (<60 μM), but it inhibited proliferation, formation migration induced by CAFs. At this concentration, inhibit CAF...
