In this Letter, we propose a symmetric metasurface composed of single-sized amorphous-silicon (a-Si) cuboids tetramer clusters that support two resonances with opposite symmetry, i.e., in-plane magnetic dipole (MD) resonance and toroidal (TD) governed by symmetry-protected bound states in the continuum (SP-BIC) near-infrared region.

Graphene provides an ideal platform for active modulation of near-field radiative heat transfer. While much research here focuses on tuning the chemical potential by doping or gating, this work proposes using a magnetic field to control flux between graphene sheets. The authors predict giant thermal magnetoresistance and negative different Fermi energies, Shubnikov-de-Haas-like oscillations in spectral flux. In static field, coupling excited magnetoplasmon-polariton modes boosts transfer...
An experimental setup has been established to investigate the thickness profiles of liquid film formed by an oblique round water jet impinging on curved walls. The influence velocity, angle, and radius curvature wall profile investigated. Both flat walls, as velocity increases, mode transitions from laminar turbulent, decreases first then increases along flow direction. transition range for walls with R = 30 mm is 19.1–25.08 m/s (Re 10 946–14 373). thicknesses increase in downstream part...
The polarized state of light scattered by media provides much more characteristic information than the intensity alone. Thus, numerous polarimetric measurements are carried out to understand characteristics. Polarized radiative transfer is used interpret these and obtain parameters, where plane-parallel approximation model usually adopted. Meanwhile, graded-index phenomenon widespread in nature, curved ray trajectory makes computation challenging. A suitable effective numerical tool great...
SignificanceOptical coherence tomography (OCT) is widely utilized to investigate brain activities and disorders in anesthetized or restrained rodents. However, anesthesia can alter several physiological parameters, leading findings that might not fully represent the true state. To advance understanding of function awake freely moving animals, development wearable OCT probes crucial.AimWe aim address challenge insufficient depth field (DOF) for imaging mice, ensuring high lateral resolution...
The recovery and repurposing of noble metal from electronic waste has attracted significant attention due to the tremendous benefits economy environment but is great challenge. Herein, a two-dimensional oxygen-rich COF material, named TbDa-COF, was fabricated via integrating 1,3,5-tris(4-formylphenyl)benzene (TFPB) 3,3'-dihydroxybenzidine (DHB) into π-conjugated framework. TbDa-COF permits selective gold through local coordination electrostatic interaction, which then followed in situ...

We propose a mechanism of active near-field heat transfer modulation relying on externally tunable metamaterials. A large effect is observed and can be explained by the coupling surface modes, which dramatically varied in presence controllable magnetoelectric finally discuss how practical picosecond-scale thermal modulator made. This allows manipulating nanoscale flux an ultrafast noncontact (by optical means) manner.

Flow control study of a circular cylinder is carried out using symmetric dielectric barrier discharge (DBD) plasma actuators at the Reynolds number 10,000. Here, two DBD are located top and bottom cylinder, respectively, each which induces pairs counter-rotating starting vortices on both sides exposed electrodes. The downstream soon take form wall jet along freestream direction. On other hand, upstream interact with incoming flow remain for some time, bringing in high momentum from to...
Convection, conduction, and thermal radiation are the three mechanisms of heat transfer in nature. The lattice Boltzmann model (LBM) has already achieved great success dealing with convection conduction problems. However, mature LBM for radiative (RHT) is still relatively lacking. Here we propose a mesoscopic RHT graded-index media, which enables simple efficient solution both transient steady-state media by conducting collision streaming processes. Via Chapman-Enskog analysis, equation...
Lean blowout (LBO) limits is critical to the operational performance of combustion systems in propulsion and power generation. The swirl cup plays an important role flame stability has been widely used aviation engines. Therefore, effects geometry flow dynamics on LBO are significant. An experiment was conducted for studying lean a single dome rectangular model combustor with cups. Three types (dual-axial cup, axial-radial dual-radial cup) were employed which operated fuel (Jet A-1) methane...
According to the Lefebvre's model and flame volume (FV) concept, an FV about lean blow-out (LBO) was proposed by authors in early study. On other hand, due parameter contained is obtained based on experimental data, could only be used LBO analysis instead of prediction. In view this, a hybrid that combines with numerical simulation present The parameters are all estimated from simulated nonreacting flows. Comparing data for 11 combustors, maximum average uncertainties ±16% ±10%.
