Abstract Zinc metal suffers from violent and long‐lasting water‐induced side reactions uncontrollable dendritic Zn growth, which seriously reduce the coulombic efficiency (CE) lifespan of aqueous zinc‐metal batteries (AZMBs). To suppress corresponding harmful effects highly active water, a stable zirconium‐based metal‐organic framework with water catchers decorated inside its sub‐nano channels is used to protect Zn‐metal. Water within narrow can constantly trap molecules solvated Zn‐ions facilitate step‐by‐step desolvation/dehydration, thereby promoting formation an aggregative electrolyte configuration, consequently eliminates corrosion reactions. More importantly, functionalized also act as ion rectifiers promote fast but even transport, leading dendrite‐free metal. As result, protected demonstrates unprecedented cycling stability more than 10 000 h ultra‐high average CE 99.92% during 4000 cycles. inspiringly, practical NH 4 V O //Zn pouch‐cell fabricated delivers capacity 98 mAh (under high cathode mass loading 25.7 mg cm −2 ) preserves 86.2% retention after 150 This new strategy in reversible anodes would spur utilization AZMBs.

This paper introduces a novel metamaterial absorber based on surface plasmon resonance (SPR). The is capable of triple-mode perfect absorption, polarization independence, incident angle insensitivity, tunability, high sensitivity, and figure merit (FOM). structure the consists sandwiched stack: top layer single-layer graphene array with an open-ended prohibited sign type (OPST) pattern, middle thicker SiO2, bottom gold metal mirror (Au). simulation COMSOL software suggests it achieves absorption at frequencies fI = 4.04 THz, fII 6.76 fIII 9.40 peaks 99.404%, 99.353%, 99.146%, respectively. These three resonant corresponding rates can be regulated by controlling patterned graphene's geometric parameters or just adjusting Fermi level (EF). Additionally, when changes between 0~50°, still reach 99% regardless kind polarization. Finally, to test its refractive index sensing performance, this calculates results under different environments which demonstrate maximum sensitivities in modes: SI 0.875 THz/RIU, SII 1.250 SIII 2.000 THz/RIU. FOM FOMI 3.74 RIU-1, FOMII 6.08 FOMIII 9.58 RIU-1. In conclusion, we provide new approach for designing tunable multi-band SPR potential applications photodetectors, active optoelectronic devices, chemical sensors.

Solar energy is currently a very popular source because it both clean and renewable. As result, one of the main areas research now investigation solar absorbers with broad spectrum high absorption efficiency. In this study, we create an absorber by superimposing three periodic Ti-Al2O3-Ti discs on W-Ti-Al2O3 composite film structure. We evaluated incident angle, structural components, electromagnetic field distribution using finite difference in time domain (FDTD) method order to investigate physical process which model achieves broadband absorption. find that distinct wavelengths tuned or resonant may be produced Ti disk array Al2O3 through near-field coupling, cavity-mode plasmon resonance, all can effectively widen bandwidth. The findings indicate absorber’s average efficiency range from 95.8% 96% over entire band 200 3100 nm, bandwidth 2811 nm (244–3055 nm) having highest rate. Additionally, only contains tungsten (W), titanium (Ti), alumina (Al2O3), materials melting points, offers strong assurance for thermal stability. It also has radiation intensity, reaching 94.4% at 1000 K, weighted 98.3% AM1.5. incidence angle insensitivity our suggested good (0–60°) polarization independence (0–90°). These benefits enable wide photovoltaic applications offer numerous design options ideal absorber.

Zn metal has received immense interest as a promising anode of rechargeable aqueous batteries for grid-scale energy storage. Nevertheless, the uncontrollable dendrite growth and surface parasitic reactions greatly retard its practical implementation. Herein, we demonstrate seamless multifunctional metal-organic framework (MOF) interphase building corrosion-free dendrite-free anodes. The on-site coordinated MOF with 3D open structure could function highly zincophilic mediator ion sifter that synergistically induces fast uniform nucleation/deposition. In addition, corrosion hydrogen evolution are significantly suppressed by interface shielding interphase. An ultrastable plating/stripping is achieved elevated Coulombic efficiency 99.2% over 1000 cycles prolonged lifetime 1100 h at 10 mA cm-2 high cumulative plated capacity 5.5 Ah cm-2. Moreover, modified assures MnO2-based full cells superior rate cycling performance.
