The dual-band electrochromic smart windows (DESW) can selectively modulate visible (VIS) and near-infrared (NIR) transmittance, which is expected to effectively reduce building energy consumption. However, the complex preparation of materials has restricted further development DESW. In this work, amorphous crystalline Ti-doped WO3·2H2O (TiWH) were synthesized by a simple precipitation method, does not require strict control oxygen content temperature. Ti doping reduced crystallinity...
Ti3C2Tx MXene is a potential microwave absorption material due to its unique physical and chemical properties. However, the impedance mismatch of results in low absorption. In this work, 2D/2D MXene@TiO2 composites were synthesized via simple hydrothermal oxidation method, TiO2 derived situ from without adding any additional Ti precursors. with permittivity can effectively regulate matching enhance loss mechanisms. The MXene@TiO2-6 h composite shows reflection (RL) −58.3 dB at 11.36 GHz...
Core–shell structures are commonly employed in microwave absorption (MA) materials due to their distinctive interfacial architecture. In this study, ferroferric oxide@polypyrrole (Fe3O4@PPy) nanocomposites with hollow core–shell were successfully synthesized for MA using a solvothermal process, followed by situ polymerization. The minimum reflection loss (RLmin) frequency of the can be precisely controlled adjusting thickness PPy shell. thickening shell enhances conduction nanocomposites,...
Dynamic multimodal optimization problems (DMMOPs) represent the that optimal solution changes over time. Due to wide application of DMMOPs in reality, some related algorithms have been proposed recent years. Most existing employ a single dynamic response mechanism and embed it multi-modal evolutionary algorithms. However, these often perform limited when environmental change involves multiple types, they fail consider utilizing historical information assist static optimizers. To solve...
In the field of electromagnetic wave (EMW) absorption, carbon matrix materials based on metal-organic frameworks (MOFs) have drawn more interest as a result their outstanding advantages, such porous structure, lightweight, controlled morphology, etc. However, how to broaden effective absorption bandwidth [EAB; reflection loss (RL) ≤ -10 dB] is still challenge. this paper, large microsphere structures Co/C composite composed small particle clusters were successfully prepared by solvothermal...
Three different dimensional BaTiO 3 nanoparticles were synthesized and doped into PDLC films. By exploring analyzing the mechanism, it was found that one-dimensional can effectively reduce operating voltage.
The MRR terminal in modulating retroreflector (MRR) free-space optical (FSO) communication system is compact and low power consumption, it expected to be equipped on mobile targets with limited payload achieve asymmetric flexible link. However, laser carrier passing through the turbulent atmosphere twice will cause more severe fading signal, severely reduce performance distance. As transmitted wave echo meet at transceiver terminal, they can naturally form homodyne detection improve receiver...
Tailoring the wavelength, bandwidth, directionality, and polarization of thermal radiation is critical for various applications like infrared camouflage, radiative cooling, gas sensing. In this work, we present a deep-subwavelength bilayer structure that serves as long-wavelength (LWIR) narrow-band emitter with selectivity. The proposed LWIR basically consists tungsten oxide (WO3) polar dielectric layer upon an opaque gold (Au) ground plane. Transfer matrix method (TMM) calculations are...
