We demonstrate that a broadband terahertz absorber with near-unity absorption can be realized using net-shaped periodically sinusoidally-patterned graphene sheet, placed on dielectric spacer supported metallic reflecting plate. Because of the gradient width modulation unit continuous plasmon resonances excited, and therefore achieved. The results show absorber's normalized bandwidth 90% absorbance is over 65% under normal incidence for both TE TM polarizations when chemical potential set as...
Abstract Highly stretchable and robust strain sensors are rapidly emerging as promising candidates for a diverse of wearable electronics. The main challenge the practical application electronics is energy consumption device aging. Energy mainly depends on conductivity sensor, it key factor in determining Here, we design liquid metal (LM)‐embedded hydrogel sensing material to overcome barrier aging simultaneously exhibits high (up 22 S m −1 ), low elastic modulus (23 kPa), ultrahigh...
Abstract Highly effective electromagnetic (EM) wave absorber materials with strong reflection loss (RL) and a wide absorption bandwidth (EBW) in gigahertz (GHz) frequencies are crucial for advanced wireless applications portable electronics. Traditional microwave absorbers lack magnetic struggle impedance matching, while ferrites stable, exhibit excellent dielectric losses, offer better matching. However, achieving the desired EBW remains challenge, necessitating further composition design....
We numerically demonstrate a broadband terahertz (THz) absorber that is based on hybrid-patterned graphene metasurface with excellent properties of polarization insensitivity, wide-angle, and active tunability. Our design made up single-layer periodically arranged hybrid square/disk/loop patterns multilayer structure. find absorption 90% absorbance the fractional bandwidth 84.5% from 1.38 THz to 3.4 can be achieved. Because axisymmetric configuration, demonstrates absolute independence for...
In hypertension-associated arteriolosclerosis cerebral small vessel disease (CSVD), various studies have shown that MRI-detected lesions—such as lacunes, white matter hyperintensities, enlarged perivascular spaces, and microbleeds—are more prevalent in deep brain regions (DBR) than the cortex. However, underlying mechanisms remain poorly understood. We propose differential vascular remodeling between DBR vessels superficial cortical branches contributes to this heterogeneity. Using a...
A well-balanced scheme for an isolated gravitational hydrodynamic system is defined as a which exactly preserves isothermal hydrostatic solution. In this paper, gas-kinetic symplecticity-preserving BGK (SP-BGK) developed. the construction of scheme, potential modeled piecewise constant function inside each cell with jump at interface. process designing such energy conservation, Liouville's theorem, and property Hamiltonian flow play important roles in description particles penetration...
Abstract Positively-charged surfaces on implants have a similar potential to upregulate osteogenesis of bone marrow-derived mesenchymal stem cells (BMSCs) as electromagnetic therapy approved for regeneration. Generally, their functions are generally considered from the charge-induced adhesion extracellular matrix (ECM) proteins without exploring underlying surface charge/cell signaling molecule pathways. Herein, positively-charged with controllable tertiary amines is produced polymer implant...
Structural simplification of the natural product sampangine led to discovery two novel antifungal compounds with excellent activity and low toxicity.
A high-order 3-D mixed spectral-element method (SEM) based on Gauss-Lobatto-Legendre polynomials in the finite-element framework is proposed to remove spurious eigenmodes numerical solution of vector Maxwell eigenvalue problem with inhomogeneous, lossy isotropic, and anisotropic media. In order suppress all zero nonzero modes that exist conventional higher SEMs, not only employs mixed-order curl-conforming basis functions for electric field intensity, but also includes divergence-free...
An efficient 2-D joint full-waveform inversion method for electromagnetic and seismic data in a layered medium background is developed. The based on the integral equation (IE) first proposed this paper. In forward computation, IE employed, which usually has smaller discretized computation domain less cumulative error compared with finite-difference method. addition, fast Fourier transform used to accelerate convolution between Green's functions induced sources due shift invariance property...
Near-infrared-responsive liquid crystal elastomers are very interesting intelligent deformable materials, which have been intensively studied in many fields such as bionics, actuators, and microrobots. However, the organic near-infrared substances used still limited. Herein, we synthesized a light-absorbing diol, has strong absorption range of 700–900 nm excellent photothermal stability under irradiation (808 nm). Subsequently, polyurethane-based elastomer developed. The obtained displayed...
