In this study, CHFs were developed by integrating Carboxymethyl Cellulose (CMC), Sodium Alginate (SA), Guar Gum (GG), and zinc oxide (ZnO) nanoparticles. The synthesized CMC–SA–GG/ZnO CHFs were characterized using AFM, SEM, FT-IR, and XRD, confirming the successful incorporation of ZnO nanoparticles into the biopolymer matrix. The CHFs exhibited excellent water absorption capacity (∼1100 % within 30 min), high biodegradability (∼98 % within 6 days), and notable mechanical stability. Their efficacy was evaluated for the adsorption and solar-responsive degradation of a model reactive textile dye effluent containing Reactive Yellow, Reactive Red, and Reactive Blue dyes. Under focused solar irradiation (240 min), the CHFs achieved a high degradation efficiency ranging from 94 % to 96 %, facilitated by their strong adsorption capacity and photocatalytic activity. Additionally, a plausible photocatalytic degradation mechanism was proposed based on radical scavenging studies suggesting O<sub>2</sub>•<sup>-</sup> and •OH were the dominant reactive species for efficient degradation. HR-MS analysis revealed the breakdown of parent dye structures into lower molecular weight intermediates and end-products, indicating effective cleavage of azo and anthraquinone chromophores. Post-treatment analysis of the effluent indicated significant improvement in water quality parameters, particularly reduction in COD and BOD, suggesting its potential reuse for domestic applications.

We investigate the tunable controllability and selective manipulation of bimeron and antibimeron pairs in two thicknesses (t = 2 and 4 nm) of Py sub-micron dot systems using magnetization reversal investigation in micromagnetic simulations. By systematically varying material parameters such as the Dzyaloshinskii–Moriya interaction (DMI) constant, dot thickness, and applying external bias fields, we demonstrate control over the nucleation, stability, and annihilation of bimeron-antibimeron pairs. Our results reveal that the size of the bimeron–antibimeron pair approximately reduces from 23 to 19 nm when the thickness of the dot is increased from 2 to 4 nm. It is also seen that the spatial separation of bimeron pairs is strongly dependent on the dot thickness.
