The degradation of methylene blue dye via tribocatalysis using 0.5Ba(Zr0.2Ti0.8)O3‒0.5(Ba0.7Sr0.3)TiO3 (BST‒BZT) ceramic powders was investigated under various conditions. The tribocatalytic process was initiated using magnetic stirring with a polytetrafluoroethylene‐coated magnetic bar in a glass beaker setup. The degradation efficiency was evaluated at different stirring speeds of 300, 500, and 700 rpm. The results showed significant variation in degradation rates, with the highest degradation efficiency of ∼73% achieved within 12 h at a rotational speed of 700 rpm. Additionally, the impact of pH on the degradation process was examined by adjusting the dye solution to pH levels of 3, 6, and 9. The degradation efficiency increased with higher pH levels, with the maximum degradation occurring in the basic medium (pH 9). Kinetic analysis revealed that the degradation process adhered to pseudo‐first‐order kinetics, with rate constants of 0.023, 0.035, and 0.104 min⁻1 at different stirring speeds of 300, 500, and 700 rpm, respectively. This study showcases the potential of BST‒BZT ceramics as efficient tribocatalysts for degrading organic pollutants in wastewater, emphasizing the impact of stirring speed and pH on degradation efficiency.

This research unveils a transformative methodology for fabricating flexible printed circuit boards (PCBs), focusing on the unique attributes of filter paper substrates. A meticulous parametric exploration scrutinizes critical aspects such as buckling resistance, charging current, plating time, and electrode configurations for copper electroplating. Key findings highlight the exceptional stability of copper electroplating on filter paper, exhibiting robust resistance against environmental variations and bending angles spanning +180° to −180°. Utilizing higher pencil grade material and maintaining a minimum 4 cm distance with a voltage range of 3 to 1.44 V ensures uniform, controlled plating without burning, optimizing the electrode area below 1 cm2 for enhanced practicality. The research underscores the longevity and durability of copper‐plated filter paper, with negligible resistance changes even after 1000 folds. Over a year, the shelf‐life assessment emphasizes the excellent stability of electroplated filter paper. Practical applications, including fully functional circuits and a bio‐degradable piano, underscore the versatility and real‐world feasibility of the proposed electroplating technique.

One of the newly light on processes utilized in applications for cleaning water is piezocatalysis. Mechanical vibrations generated through ultrasonication are generally used to separate out the charges in ferroelectric ceramics. The current research presents a novel prospective methodology of ball milling, where it is used as a facile and green technique for water remediation. The movement of the planetary ball mill imparts enough force such that reactive species are produced which are responsible for organic dye degradation. One of the results in the parametric analysis showed that by using 0.30 g of the 0.5Ba(Zr0.2Ti0.8)O3–0.5(Ba0.7Sr0.3)TiO3 (BST–BZT) powder, 62% of the methylene blue (MB) dye was degraded in 60 minutes.
