The composite effectively prevents GO restacking and enhances Fe₃O₄ dispersion, which increases interlayer spacing and exposes more active sites, thereby improving adsorption performance. The optimized composite demonstrated remarkable adsorption capacities of 1201 mg/g for Acid Fuchsin (AF) and 1135 mg/g for Amaranth (AM). Kinetic analysis revealed that adsorption was primarily governed by chemisorption, with physisorption also contributing to the overall process. Isotherm analysis fitted the Freundlich model, indicating multilayer adsorption on heterogeneous surfaces.

Furthermore, adsorption performance remained stable in tap and lake water, with only a slight decrease observed in industrial wastewater, demonstrating its practical applicability. Synergistic mechanisms including hydrogen bonding, electrostatic interactions, and π–π stacking contribute to the strong dye adsorption.

Compared to conventional rectangular waveguides, CRLH waveguides operate at infinite wavelength propagation frequency and allow the placement of apertures as excitation slots at arbitrary positions, thus enabling optimization of their design. In this work, we study two fractal designs, the Sierpinski Carpet and the Sierpinski Gasket, as excitation apertures and their impact on the uniformity of diamond films. We numerically study the electromagnetic field distributions of the fractal apertures and compare them with the corresponding distributions for conventional rectangular apertures. The optimized fractal layouts are then implemented in an in-house built SWP CVD system. We deposit nanocrystalline diamond films on 2-in. Si wafers using fractal and rectangular aperture layouts and compare the resulting film thickness variations. We show numerically that fractal aperture layouts can improve the uniformity of the electric field strength by up to 38 % compared to a slotted aperture design.
