Photonic crystal materials are developed from colloidal fibers or beads. As the have cylindrical symmetry, fiber-composed PhCs show anisotropic angle independence. By contrast, bead-composed display angle-independent structural colors because of spherical symmetry their bead elements. a service to our authors and readers, this journal provides supporting information supplied by authors. Such peer reviewed may be re-organized for online delivery, but not copy-edited typeset. Technical support...
The rational design of high-performance and cost-effective electrocatalysts to overcome the kinetically sluggish water oxidation reaction is a grand challenge in electrolysis. Transitional metals with incompletely filled d orbitals are expected have intrinsic electronic interaction promote kinetics, however, construction multiple active sites still bottleneck problem. Here, inspired by an amorphous alloy strategy chemical tunability, noble-metal-free FeCoMoPB nanoplate for superior alkaline...
The Lewis acid-catalyzed tittle reaction of 1,3-dicycloalkenlidine ketones is recognized as so far the shortest and most effective 1-step method for construction angular tricyclic scaffolds, which are extensively found in bioactive terpenoids. Here, a further kinetic study this with 30 examples carried out using situ IR technology DFT calculation. That enables creation well-fitted linear relationships lnk/(ΔG1‡/T), ΔG1‡/ΔG2, ln(k/kH)/σp, reflecting structure′s effect on...
A convenient strategy is demonstrated for placing C60 nanoclusters in hot spots between neighbouring arms of silver nano-dendrites leading to intense surface-enhanced Raman scattering (SERS) enhancement. The finite difference time domain calculations indicate that the dendrite-like model pattern may demonstrate a high quality SERS property owing 'metal/nanoclusters/metal' geometries. Further provide useful guidelines synthesis dendritic geometries and further increasing enhancement factor SERS.
The metasurface with elliptical nano-structures containing doubly degenerate geometrical charge is designed to investigate the enhanced spin-orbit optical interactions, numerically as well experimentally. It found that localized surface plasmon (LSP) resonance orbital angular momentum (i.e., rotating SP vortex mode carrying extrinsic momentum) can be induced under linearly polarized illumination. On contrary, LSP without formed circularly Moreover, based on different modes results of...
Defects or discontinuities are inevitable during the melting and consolidation process of metal additive manufacturing. Online inspection microdefects processing layer-by-layer fusion is urgently needed for quality control. In this study, laser ultrasonic C-scan imaging system established to detect surface defects selective (SLM) samples that have a different roughness. An autosizing method based on maximum correlation coefficient lag time proposed accurately measure defect length. The...
Surface enhanced fluorescence (SEF) utilizes the local electromagnetic environment to enhance from analyte on surface of a solid substrate with nanostructures. While detection sensitivity SEF is improved development nano-techniques, multiple analytes by still challenge due compromise between high enhancing efficiency and broad response bandwidth. In this article, high-efficiency bandwidth obtained embedding silver in an aluminum film produce additional bonding anti-bonding hybridized states....
With the advent of long-span bridges, steel-concrete composite decks are increasingly concerning structures to address fatigue problem, wear surfacing, and corrosion steel decks. The different types ribs result in variety cross-sections Thus, flexural behavior with perfobond rib (PBL) or head stud shear connectors was investigated this study. included (SCCDs), open-rib stiffened (OSCCDs), U-rib (USCCDs). For purpose, static tests two USCCDs PBL were conducted. Parametric analyses also...
Abstract Pore structure described the macroscopic pore size and microscopic connectivity. It heavily determined formation quality seepage capacity, thus associated with permeability. Generally, ultra-low permeability to tight sandstone reservoirs were always affected by complicated strong heterogeneity. Characterizing was of great importance in improving reservoir evaluation validity prediction. Nuclear magnetic resonance (NMR) logging considered be valuable prediction only exploration wells...
In this letter, a novel approach based on dynamic graph convolutional neural networks (DGCNNs) is proposed to analyze the quasi-periodic array consisting of cells with different geometric parameters. Each vertex node in represents cell and features each are determined by parameters corresponding cell. The connections initialized dynamically updated learn mutual coupling among cells. DGCNNs constructed trained such that can obtain relationships predict <italic...
