Two-dimensional MXenes are promising candidates for water treatment because of their large surface area (e.g., exceeding 1000 m²/g for certain structures), high electrical conductivity (e.g., >1000 S/m), hydrophilicity, and chemical stability. Their strong sorption selectivity and effective reduction capacity, exemplified by heavy metal adsorption efficiencies exceeding 95 % in several studies, coupled with facile surface modification, make them suitable for removing diverse contaminants. Applications include the removal of heavy metals (e.g., achieving >90 % removal of Pb(II)), dye removal (e.g., demonstrating >80 % removal of methylene blue), and radioactive waste elimination. Furthermore, 3D MXene architecture exhibit enhanced performance in antibacterial activities (e.g., against bacteria), desalination rejection percentage, and photocatalytic degradation of organic contaminants. However, several challenges have remained, which necessitate further investigation into toxicity (e.g., assessing effects on aquatic organisms), scalability, and cost-effectiveness of large-scale production. This review summarizes recent advancements in 3D MXene-based functional materials for wastewater treatment and water remediation, critically analyzing their both potential and limitations.

This study reports the synthesis and characterization of a magnetic composite metal-organic framework, The Fe3O4@MIL-101-OH/Chitosan nanocomposite was used for the first time to adsorb and release the drug doxorubicin (DOX). The nanocomposite was characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and vibrating sample magnetometry (VSM). The characterization results showed that the synthesized nanocomposite has a crystalline structure and good magnetic properties. Also, this nanocomposite has a high specific surface area (610.36 m2/g). In this article, the effect of pH, contact time, and drug concentration on DOX adsorption were investigated, and the results showed that at optimal conditions, pH = 8, contact time = 90 min, and drug concentration is 350 ppm, the adsorption capacity of MIL-101-OH/Chitosan and Fe3O4@MIL-101-OH/Chitosan are equal to 185 and 174.3 mg/g. The adsorption data follows pseudo-second-order kinetic and Langmuir isotherm models. The adsorption was physical and reversible. As a result, drug release was checked. The Fe3O4@MIL-101-OH/Chitosan exhibited a controlled release over the period of 84 h at pH 5 and reached 80 % of the DOX release rate after 60 h. In conclusion, the Fe3O4@MIL-101-OH/Chitosan composite has great potential as a drug delivery system as a result of its high adsorption capacity and magnetic properties. This research provides a promising approach for the development of novel drug delivery systems for cancer therapy.

The rapid growth of the human population has led to a significant increase in municipal solid waste (MSW), which is projected to reach 2.2 billion tons per year by the end of 2025. This has caused a problem with landfill leachate. Biogas production from landfill leachate offers a sustainable solution to mitigate environmental issues, including greenhouse gas emissions and groundwater contamination, while recovering clean energy and valuable resources from waste. This study simulates and assesses the environmental and economic benefits of biogas production from leachate using a life-cycle assessment (LCA) framework. The environmental impacts were evaluated using the LCA methodology and the ReCiPe 2016 midpoint (H) approach, which comprises 18 different environmental categories. Midpoint results revealed that terrestrial eco-toxicity, climate change, and fossil depletion were the main impact categories that potentially contributed to 3.63 × 101 kg 1,4-DB eq., 5.37 × 102 kg CO2 eq., and 1.83 × 101 kg oil eq., respectively, for 1 m3 of biogas production. Scenario modeling was performed by replacing the power source with a solar cell rather than grid electricity. Shifting to solar energy resulted in a GWP of 535 kg CO2 equivalent and an FDP of 18 kg oil equivalent per m3 of biogas production. Sensitivity and uncertainty analyses were conducted to evaluate environmental performance, with electricity and other inputs identified as key drivers of environmental impact. Financial analysis of 1300 m3 biogas plant reveals strong economic performance, with annual revenue of USD 651,495.98 and operational expenditures of USD 541,352.98. The project's profitability is underscored by a 2-year payback period, a positive NPV of 6,372,112.71, and an IRR of 34.53 %. While external costs, including USD 15.75 per m3 for emissions management, are notable, the environmental benefits of reduced leachate problems and electricity generation support the project's viability. This study provides policymakers, waste management practitioners, and stakeholders with valuable insights into reducing environmental impacts while increasing resource recovery from waste streams. This research aligns with several United Nations Sustainable Development Goals (SDGs), including SDG 6, 7, 11, 14, and 15, by advancing clean energy, promoting economic growth, fostering sustainable communities, and enhancing environmental protection.

This paper examines the key drivers of green innovation and its subsequent influence on environmental sustainability performance, considering the moderating effects of the green information system and technological intensity. To validate the proposed research model, ISO 14001 manufacturing enterprises were invited to participate in a questionnaire. Following the receipt of 314 responses, the first-hand data underwent analysis through structural equation modeling employing the SmartPLS software. The findings revealed that green supplier integration and green digital learning orientation are critical variables driving green innovation, while green information system functions as a moderator of the link between green digital learning orientation and green innovation. Furthermore, green innovation exhibits a positive relationship with environmental sustainability performance, and technological intensity serves as a significant moderator that amplifies this relationship. Manufacturing companies can benefit from this study by learning the key elements influencing green innovation and, subsequently, environmental sustainability performance. Green digital learning is positively related to innovation, and the correlation is stronger when a green information system is present. Green innovation also deserves considerable attention, as it largely affects environmental sustainability performance, especially when technological intensity is higher, highlighting its importance in driving sustainable outcomes.

This research explores elastomeric nanocomposites consisting of ethylene propylene diene monomer rubber/natural rubber (NR/EPDM) in various ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100 phr). The study incorporates EPDM grafted maleic anhydride (EPDM-g-MAH) as a compatibilizer, along with different quantities of Ti3C2TX reinforcement (1, 3, 5, 7, and 10 phr). To assess the dispersion and morphology of Ti₃C₂TX reinforcement in the NR/EPDM matrix, this study employed transmission electron microscopy (TEM) and scanning electron microscopy (SEM). These analyses revealed that, in the presence of EPDM-g-MAH, higher Ti3C2TX concentrations led to rougher fracture surfaces in the samples, indicating the excellent dispersion of Ti3C2TX in the NR/EPDM matrix. The investigation of mechanical and rheological properties demonstrated significant enhancements with increasing Ti3C2TX concentration in conjunction with EPDM-g-MAH. The study further explored the relationships between the nanocomposites' morphology and their theoretical and experimental mechanical properties through Mori-Tanaka analysis and dynamic mechanical thermal analysis (DMTA), respectively. These analyses revealed a strong correlation between theory and experimentation. The mechanical behavior of the composites exhibited notable improvements in tensile strength, hardness, modulus, elongation at break, and fatigue strength with the addition of Ti3C2TX, particularly in the presence of EPDM-g-MAH. Ultimately, our findings highlight the compatibility between theoretical analyses and experimental outcomes, validating the efficacy of Ti3C2TX incorporation in enhancing the properties of nanocomposites.

Abstract Ultra-high-performance concrete (UHPC) beam shear strength prediction is a complicated process due to the involvement of numerous parameters. The accuracy needed for precise predictions is frequently lacking in current empirical equations and traditional machine learning (ML) techniques. This study proposes hybrid ML models that integrate three nature inspired metaheuristic algorithms—Giant Armadillo Optimization (GOA), Spotted Hyena Optimization (SHO) and Leopard seal optimization (LSA)- Extreme Gradient Boosting (XGB) to predict the shear strength of UHPC beams. A comprehensive dataset was created from extensive literature reviews and trained and tested on the models using multiple input parameters that affect UHPC’s shear capacity. For model assessment, performance metrics, such as coefficient of determination (R2, root mean square error (RMSE), mean absolute error (MAE), and variance accounted for (VAF), were utilized. Results showcased high accuracy, with R2 values approaching 0.9912 in training and 0.9802 in testing phases using the LSA-XGB algorithm, indicating excellent model fit and predictive reliability. To improve the model’s transparency and interpretability, the study also incorporates shapely additive explanations (SHAP), which reveal how each dataset attribute affects the predictive results. The LSA-XGB algorithm performed better than prior studies and empirical equations in predicting the shear strength of UHPC beams. More sophisticated machine learning techniques that improve the precision of predicting the shear capacity of UHPC beams are demonstrated in the study. Further, the use of a graphical user interface (GUI) helps researchers and engineers to make quick, well-informed decisions in real-time. These findings offer a reliable, interpretable, and accessible approach to predicting shear strength in UHPC beams, contributing to safer structural engineering practices.

The distinctive benefits and drawbacks of various drug delivery strategies to supply corneal tissue improvement for sense organs have been the attention of studies worldwide in recent decades. Static and dynamic barriers of ocular tissue prevent foreign chemicals from entering and inhibit the active absorption of therapeutic medicines. The distribution of different medications to ocular tissue is one of the most appealing and demanding tasks for investigators in pharmacology, biomaterials, and ophthalmology, and it is critical for cornea wound healing due to the controlled release rate and increased drug bioavailability. It should be mentioned that the transport of various types of medications into the different sections of the eye, particularly the cornea, is exceedingly challenging because of its distinctive structure and various barriers throughout the eye. Nanoparticles are being studied to improve medicine delivery strategies for ocular disease. Repetitive corneal drug delivery using biodegradable nanocarriers allows a medicine to remain in different parts of the cornea for extended periods of time and thus improve administration route effectiveness. In this review, we discussed eye anatomy, ocular delivery barriers, as well as the emphasis on the biodegradable nanomaterials ranging from organic nanostructures, such as nanomicelles, polymers, liposomes, niosomes, nanowafers, nanoemulsions, nanosuspensions, nanocrystals, cubosomes, olaminosomes, hybridized NPs, dendrimers, bilosomes, solid lipid NPs, nanostructured lipid carriers, and nanofiber to organic nanomaterials like silver, gold, and mesoporous silica nanoparticles. In addition, we describe the nanotechnology-based ophthalmic medications that are presently on the market or in clinical studies. Finally, drawing on current trends and therapeutic approaches, we discuss the challenges that innovative optical drug delivery systems confront and propose future research routes. We hope that this review will serve as a source of motivation and inspiration for developing innovative ophthalmic formulations.
