This paper thoroughly investigates the toxicity and environmental burden of wastewater from the Fischer-Tropsch catalytic synthesis process. This significant by-product was analysed through the means of root growth inhibition of <em>Sinapis alba</em>, acute lethal effects on <em>Eisenia andrei</em>, chromatography on organic compounds, and determination of the content of metals. Two samples based on Co and CoMnK fixed bed catalytic synthesis using a standard range of parameters (250–280 °C; 1.5 MPa; 1145 h<sup>–1</sup>) were prepared. The results showed a severe toxicological effect in all investigated means. Significant Co, Mn, and K occurrences were detected in wastewater in amounts of 0.40–0.57, 0.83, and 0.13 mg·l<sup>–1</sup>, respectively. The root growth inhibition test proved that only 9.85 % solution is necessary to reach a 50 % growth inhibition in the case of Co synthesis. CoMnK synthesis presented slightly less toxic results – 11.75 % solution for 50 % growth inhibition. Similarly, Wastewater Co with lethal concentration LC50 87.74 % was more toxic to earthworms than Wastewater CoMnK with LC50 95.99 %. The level of toxicity of this widely produced substance was surprisingly high. Rising environmental protection activity is expected to prove problematic for the current or future industrial applications, and a need to adopt treatment processes discussed in this study or upgrade the existing ones might be of the essence.

These self-powered systems can convert biomechanical, biochemical, and body heat energy into electrical signals, facilitating the long-term, real-time monitoring of physiological states. Key technologies driving energy conversion in self-powered smart textiles include triboelectric nanogenerators (TENGs), piezoelectric nanogenerators (PENGs), magnetoelastic generators (MEGs), thermoelectric generators (TEGs), and biofuel cells (BFCs).

This review aims to fill this gap by providing an extensive overview of self-powered smart textiles with a focus on their materials, energy-harvesting technologies, and emerging applications. It explores the principles of energy harvesting and storage integrated into textiles, examines advanced materials and fabrication strategies, and highlights key applications in the healthcare, fitness, military, fashion, and industrial sectors.

This study evaluates the hosting capacity of PV systems (HCPV) in real distribution networks in Puerto Rico, analyzing six feeders with different characteristics in topology, length, load, voltage, and geographical location. Increasing PV penetration scenarios and time variations were simulated by modeling detailed distribution feeders using OpenDSS, and the results were processed in MATLAB. Strategies to increase HCPV, such as using a battery energy storage system (BESS) and the Volt-VAr control function of smart inverters (SI), were also evaluated. The results show that HCPV varies seasonally and that feeders operating at 13.2 kV are less susceptible to voltage violations than those operating at 8.32 kV and 4.16 kV. In addition, the combination of BESS with the Volt-VAr function of the SI was the most effective strategy for increasing the HCPV.

This scheme not only guarantees fast convergence but also ensures that the convergence time is independent of the system’s initial conditions, which is a significant improvement over traditional finite-time and fixed-time consensus methods. Moreover, the prescribed-time control strategy offers flexibility by allowing the convergence time to be adjusted according to specific application requirements, making it more adaptable to real-world conditions. Using the Lyapunov stability theorem, we rigorously prove the stability of the proposed control scheme, ensuring that the system’s dynamic performance remains robust. Compared to existing methods, the proposed strategy reduces the conservativeness in estimating the upper bound of the convergence time, thereby enhancing system stability and improving microgrids’ power quality. The effectiveness of the proposed control approach is further validated through experiments across various scenarios, demonstrating its capability to achieve rapid and reliable consensus in DC microgrids.
