The high-temperature solid-phase approach was used to synthesize Eu3+-doped SrMo0.5W0.5O4 phosphors, whose morphological structure and luminescence properties were then characterized by XRD, SEM, FT-IR, excitation spectra, emission fluorescence decay curves. results reveal that the best phosphor synthesis temperature 900 °C doping of Eu3+ charge compensators (K+, Li+, Na+, NH4+) had no effect on crystal phase change. SrMo0.5W0.5O4:Eu3+ has major peaks at 273 nm, 397 464 a main peak 615...
Abstract Bismuth–antimony alloy is considered as a promising potassium ion battery anode because of its combination the high theoretical capacity antimony and excellent rate bismuth. However, large volume change sluggish reaction kinetic upon cycling have triggered severe fading poor performance. Herein, nanoconfined BiSb in tremella‐like carbon microspheres (BiSb@TCS) are delicately designed to address these issues. As‐prepared BiSb@TCS renders an outstanding potassium‐storage performance...
The lithium-sulfur battery is currently considered to be a promising candidate for next-generation energy storage devices. However, its commercial application severely restricted by rapid capacity decay mainly arising from unavoidable dissolution of intermediate lithium polysulfide the S-based cathodes. Herein, multifunctional stripped grapheme-carbon nanotubes (SG-CNT) with 1D/2D interwoven and hierarchical pore structure as host stabilize S was constructed cheaper raw materials facile...
Single-photon emitters (SPEs) play an important role in many optical quantum technologies. However, efficient large-scale approach to the generation of high-quality SPE arrays remains elusive goal at room temperature. Here, we demonstrate a scalable method generating hexagonal boron nitride (hBN) with high yield, brightness, and purity using single-pulse irradiation by femtosecond laser. Our use single pulse per defect pattern minimized heat-related damages improved SPEs compared previous...
Abstract Nanomaterials-based photoluminescence thermometry (PLT) is a new contact-free photonic approach for temperature sensing, important applications ranging from quantum technology to biomedical imaging and diagnostics. Even though numerous materials have been explored, great challenges deficiencies remain that hamper many applications. In contrast most of the existing approaches use large ensembles rare-earth-doped nanomaterials with volumes unavoidable inhomogeneity, we demonstrate...

Current state-of-the-art document retrieval solutions mainly follow an index-retrieve paradigm, where the index is hard to be directly optimized for final target. In this paper, we aim show that end-to-end deep neural network unifying training and indexing stages can significantly improve recall performance of traditional methods. To end, propose Neural Corpus Indexer (NCI), a sequence-to-sequence generates relevant identifiers designated query. optimize NCI, invent prefix-aware...
Abstract Multi-stage centrifugal pumps are frequently used in high-lift applications and consume considerable energy, but suffer from poor performance large axial force. The rear shroud of impeller is trimmed for reducing thrust, this degrades performance. This study analyzes degradation optimizes Experiments simulations conducted on different ratios to front (λ). Total pressure losses calculated, flow visualized using the entropy generation method. Both measured simulated performances...
Abstract Nickel‐rich cathode materials have gained popularity in the development of lithium‐ion batteries (LIBs) due to their high energy density, which exceeds 250 Wh kg −1 . However, instability bulk and surface structures has significantly limited industrial application.

Nanoscale self-assembly offers a pathway to realize heterogeneous integration of III-V materials on silicon. However, for nanowires directly grown silicon, dislocation-free single-crystal quality could only be attained below certain critical dimensions. We recently reported new approach that overcomes this size constraint, demonstrating the growth InGaAs/GaAs and InP nanoneedles with base diameters exceeding 1 μm. Here, we report distinct optical characteristics which are varied from mostly...
