Plasmonic nanolasers have ultrahigh lasing thresholds, especially those devices for which all three dimensions are truly subwavelength. Because of a momentum mismatch between the propagating light and localized optical field subwavelength nanocavity, poor pumping efficiency is another important reason threshold but normally always ignored. On basis cavity-embedded nanoantenna array design, we demonstrate room-temperature low-threshold plasmonic nanolaser that robust, reproducible,...

We report the synthesis of single-crystal La0.67Sr0.33MnO3 (LSMO) freestanding films with different crystal orientations. By using pulsed laser deposition, water soluble perovskite-like sacrificial layers Sr3Al2O6 (SAO) followed by LSMO are grown on differently oriented SrTiO3 substrates. Freestanding orientations obtained etching SAO in pure water. All show room-temperature ferromagnetism and metallicity, independent orientation. Intriguingly, Curie temperature (TC) is increased due to...

The traditional view holds that the dominant deformation mechanism of Ni-based single crystal superalloys at intermediate temperatures (both in tension and creep) is stacking fault shearing γ' phases. Here, we provide direct evidence to prove mechanisms creep are different. orientation rotation path during tensile 750 °C has been observed by in-situ electron back-scattered diffraction (EBSD). result indicates temperature movement matrix dislocations, which different from process,

The solidification characteristics and as-cast microstructures of a Ru-containing nickel-based single crystal superalloy were systematically investigated through thermal analysis, Thermo-Calc simulation, the planar interface experiment, directional quenching experiment. main transition temperature, segregation behavior, path analyzed, microstructure evolution phase formation mechanism also discussed. began with primary γ dendrites (L → γ). Then Ni, Al, Ta, Ru enriched in residual liquid,...

Quartz nanopipette-based carbon nanoelectrodes (CNEs) have attracted extensive attention in nanoscale electrochemistry due to their simple and efficient fabrication, chemically inert materials, flexible size (down a few nanometers), ultrathin insulating encapsulation. However, these pristine CNEs usually significantly irregular morphology on the surface, which greatly limits applications where inlaid nanodisks are urgently needed. To address this critical issue, we developed new precise...

The stability of microstructure and mechanical properties 9Cr heat resistant steel under high temperature long term service conditions has been a hot issue great interest. In the present study, relationships between evolutions deposited metals with different Si contents (0.25 wt.% 1.07 wt.%) at 550 °C aging for times were investigated systematically. results indicate that degradation during is mainly attributed to coarsening precipitates, transformation precipitate types, decreasing...

In this work, three types of bainite microstructure have been gained in the deposited metals by adjusting Ni content (1 wt %, 2.5 and 4 %). The feature different has characterized optical microscope, scanning electron transmission backscattering diffraction. Microstructure changed from granular with morphology to lath increase content. number elongated Martensite-Austenite constituents increased increasing 1 % due hardenability. complex orientation metal attributed numerous autocatalytic...

Understanding the distribution of atmospheric water vapor (H2O) is crucial for global warming studies and climate change mitigation. In this study, we retrieved ground layer, tropospheric total columns H2O using ground-based high-resolution Fourier transform infrared spectrometry (FTIR). The are obtained from near-infrared (NIR) mid-infrared (MIR) spectra, layer MIR spectrum. NIR have a good consistency (R = 0.989). Additionally, similar seasonal variation to but higher amplitude. close in...
