We propose ultrathin multiband metamaterial absorbers in the microwave frequencies which design, analysis, fabrication, and measurement of working multiple bands are presented. The consist a periodic arrangement different scales electric-field-coupled-LC (ELC) resonators metallic background plane, separated by only 1 mm dielectric spacer. By tuning scale factor ELC unit cells, we achieve independently absorptions at customized frequencies. Experiments demonstrate excellent absorption rates...
BACKGROUND The aim of this study was to design and test a novel composite scaffold with antibacterial efficacy for treating bone infections using three-dimensional (3D) printed poly(ε-caprolactone) (PCL) coated polydopamine (PDA) the adsorption polylactic acid-glycolic acid (PLGA) microspheres loaded vancomycin. MATERIAL AND METHODS Vancomycin-loaded PLGA were produced by double-emulsion method, microsphere morphology, drug-loading dosage, encapsulation efficiency, average diameter, release...
This research delves into the impact of incorporating thermally treated oyster shell powder (TOS), a biowaste filler, low-density polyethylene (LDPE) to develop LDPE/TOS blend, aiming at enhancing food packaging materials. The blend portrays advantageous characteristics such as augmented mechanical strength, thermostability, crystallinity, water absorption, and improved hydrophobicity with TOS content up 50%. Microstructure analysis reveals transition from sparse more interconnected...
We propose, design, and experimentally demonstrate three-dimensional 3-D anisotropic zero-index lenses, which can improve the directivity of traditional antennas. show that a lens with εu → 0 is efficient to transverse magnetic (TM) modes decrease beam width main lobe in E-plane; while μu electric (TE) reduce H-plane, u represents propagating direction. If such two lenses are packed together, both E- H-planes significantly improved. To verify this unique property, we design fabricate four...
Abstract Hydrogels with excellent stiffness, toughness, anti‐fatigue, and self‐recovery properties are regarded as promising water‐containing materials. In this work, a dual physically cross‐linked (DPC) sodium alginate (SA)/poly[acrylamide (AAm)‐acrylic acid (AAc)‐octadecyl methacrylate (OMA)]‐Fe 3+ hydrogel is reported, which constructed by hydrophobic association (HA) ionic coordination (IC). The optimal DPC demonstrates mechanical performance: tensile modulus of 0.65 MPa, strength 3.31...
Abstract The parasitic absorption effect of metal nanoparticles in the dye‐sensitized solar cells (DSSC) was investigated using finite difference time domain technique. It shown that conversion efficiency can be improved up to 15–20% DSSC device with an optimized nanoparticle array 210 nm diameter and 500 period, but even under conditions, take about 20–30% total at visible wavelengths. heat loss smaller (70 nm) light wavelengths is far greater than electromagnetic energy scattered into...
Urchin‐like Ag/ZnO hierarchical nano/microstructures have been synthesized through a facile low‐temperature hydrothermal growth method based on galvanic replacement mechanism.

In this paper, hierarchical CuO/MnO 2 composite hollow nanospheres have been successfully fabricated by water evaporation-induced self-assembly through a redox transformation reaction between Cu O and KMnO 4 solution at 120[Formula: see text]C for 6[Formula: text]h, followed removing the residual cores with ammonia hydroxide solution. The outstanding feature of method is that system in dynamic environment due to evaporation solvent water, which benefits nanostructures form structures. Both...
Abstract The dependence of the optical magnetic property on metal film thickness and origin in thick (silver) perforated with rectangular nanohole arrays were investigated using finite‐difference time‐domain technique. A negative permeability was observed range where two hybridized plasmon polariton resonances are present, a big at certain when antisymmetric coupling between electrical current density near top bottom plane directions present. Two types found to probably contribute permeability.

As result coupling between top down surface plasmon polaritons, mediated by localized resonances supported metallic nano- holes, interesting light phenomena are observed for varying arrays. Based possibility exploiting as plasmonic sensors further discussed, potential...
