Nanoparticles induced neurotoxicity

Nanotoxicology, Год журнала: 2025, Номер unknown, С. 1 - 28

Опубликована: Апрель 16, 2025

The early development of nanotechnology has spurred major interest on the toxicity nanoparticles (NPs) due to their ability penetrate biological barriers such as BBB. This review aims at addressing how silver (AgNPs), titanium dioxide (TiO2NPs), zinc oxide (ZnONPs), iron (Fe3O4NPs), carbon NPs, Copper (Cu-NPs), silicon (SiO2 NPs) and quantum dots cause neurotoxicity. Some signaling that occur are related oxidative stress, neuroinflammation, mitochondrial dysfunction cell equilibrium, hence results in neuronal damage neurodegeneration. It is critical describe there multiple ways by NPs may be toxic based size surface, dosage, recipient's age health condition. A vitro vivo analysis provides information about potentials preventive measures including modification NP surface antioxidant treatment. underline necessity comprehensive safety assessments allow further utilization across economy.

Recent Applications, Challenges, and Future Prospects of Microbial Fuel Cells: A Review

Global Challenges, Год журнала: 2025, Номер unknown

Опубликована: Апрель 16, 2025

Abstract Microbial fuel cell (MFC), a clean and promising technology that has the potential to tackle both environmental degradation global energy crisis, receives tremendous attention from researchers over recent years. The performance of each system component, including membrane electrode utilized in MFCs, great effect on efficiency converting chemical found organic waste power generation through bacterial metabolism. MFCs have diverse applications are growing day by developed countries. This review discusses recently available various wastewater treatment, biohydrogen production, hazardous removal, bioelectricity, robotics, biosensors, etc. There still several challenges (e.g., complexity, economic, commercialization, other operational factors) for large‐scale practical applications, particularly relatively low output delayed start‐up time, which is also reported this article. Moreover, factors materials, proton exchange system, substrate, electron transfer mechanism, pH, temperature, external resistance, shear stress feed rate) affect discussed detail. To resolve these issues, optimizations parameters presented. In previously published studies, paper indicates demonstrated densities ranging 2.44 3.31 W m − 2 , with Coulombic efficiencies reaching up 55.6% under optimized conditions. It achieved removal oxygen demand (COD), total carbon (TOC), antibiotics 93.7%, 70%, 98%, respectively. Finally, highlights future perspective full‐scale applications.

Utilizing Household Organic Waste as a Precursor for Carbon Nanomaterial Production: Challenges and Outlook for Sustainable Waste Management

IOP Conference Series Earth and Environmental Science, Год журнала: 2024, Номер 1425(1), С. 012018 - 012018

Опубликована: Дек. 1, 2024

Abstract Household organic waste accumulates daily, posing a significant environmental issue due to inadequate treatments and insufficient disposals. The negative impacts include air water pollutions, ecosystem damage, worsening of human health. Carbon nanomaterials (CNMs) are emerging as an innovative solution with easy manufacturing process wide applications in various fields. Utilizing household precursor for CNMs opens up opportunities create useful sustainable products, well reducing the amount waste. produced two-step low heating (TSLH) method using oven microwave. then characterized particle size analyser (PSA) determine their distributions. PSA test results show that dominant distribution is 651 nm. Furthermore, found be 90.3 nm percentage 6.4%, which accordance nanoparticle requirement (below 100 nm). treatment into takes 5 7 days 99.66% reduction challenges here detected sorting filtering durations These findings open further research understand impact potential resulting nano-sized context management technology.
