The nanoparticles, characterized by a spinel structure with direct and indirect band gaps of 1.46 eV and 0.9 eV, respectively, demonstrate exceptional structural, optical, dielectric, and catalytic properties. Dielectric analysis reveals strong frequency- and temperature-dependent behaviour, with high dielectric constants at low frequencies and conduction mechanisms dominated by polaron hopping and defect states. Using the Havriliak–Negami model, the study highlights temperature-dependent relaxation times and dielectric constants, further elucidating the nanoscale interfacial dynamics governing these phenomena. The nanoparticles achieved a remarkable 97% degradation of H<small>₂</small>O<small>₂</small> in just 150 minutes at room temperature, following first-order kinetics with a rate constant of 3.39 × 10<small>⁻⁴</small> s<small>⁻¹</small>. The superior performance is attributed to their high surface area (269.67 m<small>²</small> g<small>⁻¹</small>) and small crystallite size (14.78 nm), which optimize their surface and interface properties.

This study investigates the use of chalcopyrite mineral nanoparticles (CP NPs), derived from natural and sustainable sources, as efficient, recyclable, and scalable adsorbents for the removal of organic dyes from aqueous solutions. The CP nanoparticles have been thoroughly characterized using spectroscopic and microscopic techniques to determine their size, shape, elemental composition, and the oxidation states of the constituent elements. Due to their high surface area, unique electronic properties, and structural stability, chalcopyrite nanoparticles demonstrate promising potential in capturing and eliminating various dye pollutants from water.

We explored adsorption efficiencies using methylene blue dye, concentrations, and environmental conditions, showing that CP NPs offer high dye removal rates and rapid adsorption kinetics.

However, extensive postprocessing is needed to reduce their cytotoxicity. In this study, we demonstrate that a 60-minute “wet” autoclave process significantly reduces leachates compared to many commonly used postprocessing methods. This reduction in leachates was observed across all four tested resins, indicating the general applicability of this method. Materials marketed as biocompatible did not affect stem cell growth and only had a minor effect on differentiation after a 60-minute wet autoclave treatment, unlike non-wet autoclaved parts, which showed marked effects. We assessed cellular function using morphology, viability assays, functional assays, and metabolomics. While no immediate effects were observed from the tested materials after wet autoclavation, transcriptomic analysis revealed that sub-cytotoxic levels of leachates downregulated extracellular matrix genes and upregulated genes related to cell adhesion and lipid and fatty acid metabolism. These changes could have long-term implications.

Electronic structure analyses performed using both the generalized gradient approximation (GGA) and the Tran–Blaha modified Becke–Johnson (TB-mBJ) potential reveal that these materials exhibit semiconducting ferromagnetism, characterized by a significant spin-splitting gap. The underlying mechanism is traced to the crystal field effects influencing the d-orbitals of the transition metal atoms.

However, this remains a challenge due to the inherently irregular microstructure of textile fibres, particularly in natural fibres. Plasma treatment is widely used in e-textile research. However, the effects of plasma treatment parameters on the electrical resistance of subsequently coated e-textiles has not been systematically investigated. This research is the first to comprehensively evaluate how plasma pre-treatment affects the electrical resistance of e-textiles, providing critical insights for optimising the fabrication process. A Taguchi design of experiment was used to examine four fabrics (linen, polyester, nylon, wool) subsequently coated with MXene, and several plasma treatment parameters (power, flow rate, time, gas). The study presents exceptional findings demonstrating the impact of optimally selected plasma treatment parameters on the subsequent electrical resistance of MXene-coated (MC) e-textiles. Each fabric type exhibits a highly significant reduction in electrical resistance when treated with the optimal plasma parameters compared to the MC-control samples. For example, MC-wool's electrical resistance was lowest using hexafluoroethane with a median electrical resistance of 345 Ω; a 99.96% decrease in electrical resistance compared to the median electrical resistance of the control MC-wool fabric. Air treatment was optimal for Nylon demonstrating a median of 22 Ω–99.7% decrease in electrical resistance from the MC-Nylon control sample.
