Summary: Carbon-based nanomaterials have become widely used in industries due to their unique properties, attracting increasing attention. However, their toxicity and environmental effects, especially on aquatic biota, require careful study. This research investigated the toxicity of oxidized multi-walled carbon nanotubes (Ox-MWCNTs) on freshwater bivalves and evaluated their impacts on antioxidant defenses. The results showed a concentration-dependent response of antioxidant enzymes in the bivalves exposed to different concentrations of Ox-MWCNTs, suggesting potential risks to aquatic ecosystems and human health if contaminated animals are ingested.

Summary: Chemical functionalization of carbon nanotubes using a mix of sulfuric and nitric acids enhances their hydrophilicity, which improves their dispersion in water and cement matrix. This study treated multi-walled carbon nanotubes with acid and used them to prepare solutions with low amounts of poly-carboxylate ester (PCE) by ultrasonic sonication. The acid-treated carbon nanotubes contained 13% carboxyl functional groups and showed increased hydrophilicity and better bonding with cement hydration products. The addition of acid-treated carbon nanotubes resulted in a 55% increase in the mechanical strength of cement paste.

Summary: Nitrogen-doped multiwalled carbon nanotubes (N-doped MWCNTs) are effective catalysts that can improve diesel engine performance and reduce exhaust emissions. Adding N-doped MWCNTs to diesel fuel significantly enhances combustion behavior, engine performance, and exhaust emission analysis. It increases in-cylinder pressure and heat release rate, improves brake thermal efficiency, reduces brake specific fuel consumption, and significantly reduces NOx, soot, and CO formations in exhaust emissions compared to diesel and MWCNTs blends.

Summary: This paper presents a method for 3D printing self-heating structures by embedding conductive layers in a thermoplastic matrix using a dual-nozzle setup. The method utilizes a suspension of carbon nanotubes and short carbon fibers, which form a thin conductive film after the solvent evaporates. The resistive heater embedded in the structure can generate temperatures up to 200 degrees C and can be controlled by adjusting electrical parameters and modifying the suspension. The results demonstrate that 3D-printed self-heating structures offer better design and multi-material capabilities compared to traditional manufacturing methods, while maintaining Joule heating performance.

Summary: This study characterized the chemical and toxicological properties of water-soluble particulate matter in the urban area of Thessaloniki, Greece, during different seasons. The analysis included water-soluble organic carbon, humic-like substances, and trace elements. Results showed that humic-like substances were a significant component of water-soluble organic carbon, and their concentrations varied among seasons and particle sizes. The most abundant water-soluble metals were Fe, Zn, Cu, and Mn. The oxidative potential and cytotoxicity of particulate matter were positively correlated with water-soluble organic carbon and humic-like substances.

Summary: Polyphenols have complex antioxidant properties, including pro-oxidant effects and complex behavior in the presence of multiple polyphenols. This study aimed to investigate the intracellular redox activity of resveratrol and quercetin alone and in mixture in a cellular bioassay. The results showed that quercetin exhibited antioxidant activity, while resveratrol had weaker antioxidant effects when used alone. The equimolar mixtures of these polyphenols showed interactions, with additive effects at lower concentrations and synergic effects at higher concentrations.

Summary: In this experiment, groups of zebrafish embryos were exposed to radiations of different frequencies and intensities using new prototype devices. The radiations included static, extremely low-frequency, low-frequency, very-high-frequency, and ultra-high-frequency fields. The exposure led to alterations in body pigmentation of the zebrafish embryos and larvae. These findings contribute to understanding the effects of magnetic radiation on living organisms.

Summary: Aquatic invertebrates are important for (eco)toxicological assessments due to their ethical, cost-effective, and repeatable testing options. However, current standardized protocols mainly focus on a limited number of aquatic invertebrate species, limiting the scope of basic ecotoxicological studies. This review emphasizes the need for a broader taxonomic approach and the use of diverse scientific techniques to comprehensively assess the impact of chemicals in aquatic environments.

Summary: Transitional waters are precious habitats for rare and endangered species, but they are vulnerable to human-induced threats. This review examines the suitability of Aphanius fasciatus as a sentinel species for assessing the quality of transitional water environments. The study suggests that the molecular, cellular, and physiological responses of A. fasciatus can serve as diagnostic tools for detecting the subtle effects of environmental pollution. Omics technologies show great potential in understanding organisms' responses to environmental changes, highlighting the need to improve omics tools for A. fasciatus in the future.

Summary: This study aimed to investigate the cytotoxic effects of PM10 on A549 cells and the cellular mechanisms underlying the induction of AVD and oxidative stress. The results showed that winter PM10 samples with high PM10 value and organic carbon content exhibited cytotoxic effects leading to apoptotic death in A549 cells. Exposure to PM10 aqueous extracts induced AVD and oxidative stress, which were correlated with cell viability inhibition and apoptotic cell shrinkage.
