In this paper, we design a polarization-independent and angle-insensitive broadband THz graphene metamaterial absorber based on the surface plasmon-polaritons resonance. Full-wave simulation is conducted, results show that designed has an absorption above 99% in frequency range from 1.23 to 1.68 THz, which refers very high standard. Furthermore, properties of tunability, can be nearly adjusted 1% by varying Fermi energy level 0 eV 0.7 eV. simulation, when incident angles TE TM waves change...
Here we introduce the electromagnetic shielding effectiveness (SE) of reduced graphene oxide (RGO) sheets interleaved between polyetherimide (PEI) films fabricated by electrophoretic deposition (EPD). Incorporating only 0.66 vol % RGO, developed PEI/RGO composite exhibited an interference (EMI SE) at 6.37 dB corresponding to ∼50% incident waves. Excellent flexibility and optical transparency up 62% visible light was demonstrated. It achieved placing RGO in localized area as a thin film (ca....
Portable energy storage devices have gained special attention due to the growing demand for portable electronics. Herein, an all-solid-state supercapacitor is successfully fabricated based on a poly(vinyl alcohol)-H3PO4 (PVA-H3PO4) polymer electrolyte and reduced graphene oxide (RGO) membrane electrode prepared by electrophoretic deposition (EPD). The RGO EPD contains in-plane layer-by-layer alignment moderate porosity that accommodate ions. thoroughly tested give high specific volumetric...
Biomass waste treatment and detrimental dye adsorption are two of the crucial environmental issues nowadays. In this study, we investigate to simultaneously resolve aforementioned by synthesizing chitosan sponges as adsorbents toward rose bengal (RB) adsorption. Through a temperature-controlled freeze-casting process, robust recyclable fabricated with hierarchical porosities resulted from control concentrations solutions. Tested for RB, best our knowledge, as-prepared sponge in work reports...
The popularity of smartphones has grown at an unprecedented rate, which makes smartphone based imaging especially appealing.
