Article Abstract
The continuous advancement and miniaturization of modern electronics have increased challenges related to electromagnetic interference (EMI) and thermal management. Polymer materials are commonly used for thermal regulation and EMI shielding because of their low weight, cost-effectiveness, and ease of processing. However, achieving both high electromagnetic shielding effectiveness (SE) and superior thermal conductivity (TC) in polymeric systems remains a major scientific challenge. In this study, a lightweight and flexible amino-functionalized multiwalled carbon nanotube-graphene nanoplatelet/poly(p-phenylene benzodioxazole)/poly(ether-ether-ketone) composite film (NH-MWCNTs&GnPs@PBO/PEEK, NH-MGPP) is fabricated using vacuum-assisted filtration. As a result, the NH-MGPP film (0.05 mm thick) exhibited exceptional EMI shielding performance (71.47 dB) and in-plane thermal conductivity (36.78 W mK). The composite also demonstrated rapid Joule heating kinetics and an efficient photothermal response, enabling effective thermal management and energy harvesting capabilities. When integrated into a solar-thermoelectric generator, the NH-MGPP film produced an output voltage of 1004.9 mV under 5 kW m simulated sunlight irradiation, confirming its high photo-thermal-electrical energy conversion efficiency. This study presents an innovative approach for designing and developing flexible composite films with excellent electromagnetic shielding properties and efficient heat dissipation capabilities. Additionally, it introduces a new method for the effective utilization of renewable energy.

The long-term accumulation of electrolytic manganese residue leads to pollution issues related to NH -N and Mn. Although various methods exist to address the pollution caused by NH -N and Mn, existing hazard-free treatment methods do not consider the subsequent utilization of the electrolytic manganese residue. Meanwhile, resource recovery methods face challenges due to the complex salt structures present in electrolytic manganese residue.

Optimizing the collection chamber structure is critical for improving the reliability of electrostatic radon detectors, which are key to environmental and health risk monitoring. This study used COMSOL simulations to explore polonium-218 (Po, a radon progeny) ion collection parameters: chamber geometry, voltage, base material and structure, detector configuration, and edge electrification. Results showed that an uncharged base, combined with a detector protruding 2 mm above the base, enhances collection efficiency (CE); charged metal edge shielding boosts CE by 4-10 % without increasing collection time (CT); ∼2000 V balances peak CE and electromagnetic interference suppression.

This review study examines an innovative biotechnological strategy aimed at creating a specialized cyanobacterial ecosystem designed to produce high-quality biomass abundant in compounds that provide protection against solar radiation, specifically scytonemin and mycosporine-like amino acids (MAAs). The remarkable ability of cyanobacteria to produce biomass that is both sustainable and environmentally friendly has attracted considerable attention in recent years, largely due to its wide-ranging applications in various industries. However, a significant challenge remains: the concentrations of these beneficial metabolites within cyanobacteria are typically very low, rendering industrial-scale production economically unviable.

Rapid strides in portable electronics and telecommunication technologies have sharply escalated the demand for high-performance electromagnetic interference (EMI) shielding materials that effectively suppress secondary electromagnetic pollution while simultaneously integrating thermal management. Here an innovative, lightweight, hierarchical triple-layer aerogel structure comprising nickel (Ni) foam (NiF), titanium carbonitride (TiCNT) MXene, and poly(vinyl alcohol) (PVA), fabricated via a facile, one-step bidirectional freeze-casting process is presented. This asymmetric aerogel architecture strategically employs an impedance-matching MXene/PVA top layer for optimized microwave entry, a NiF/MXene/PVA interlayer introducing magnetic loss and enhancing heat conduction, and a reflective, thermally foamed MXene bottom layer promoting internal reflection for superior energy absorption.
