Nanotechnology provides innovative tools for medicine, agriculture, and environmental applications. Iron oxide nanoparticles (Fe2O3 NPs) are of particular biomedical interest due to their biocompatibility, magnetic properties, and therapeutic potential. Harnessing the phytoconstituents of F. indica for nanoparticle fabrication offers a sustainable approach to generate biofunctional nanomaterials with enhanced therapeutic efficacyIn this study, Fe2O3 NPs were biosynthesized using F. indica extract through a green and cost-effective method. The nanoparticles were characterized using Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet–Visible Spectroscopy (UV–Vis), Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS), and Energy Dispersive X-ray Spectroscopy (EDX), confirming their rectangular (average size of 65 nm) morphology, functional group interactions, and elemental composition of iron and oxygen. The bio-fabricated Fe2O3 NPs displayed broad pharmacological activities: strong antileishmanial (71
Biological invasions, driven by the spread of non-native species, have become a critical global issue because of their far-reaching ecological and socioeconomic impacts. Effective communication of the risks of biological invasions is essential for implementing robust policy and legislation and gaining public support for conservation efforts. However, current policies often suffer from fragmentation and ineffectiveness, largely due to inadequate risk communication and complex multi-level governance. To address this challenge, we develop a global framework designed to enhance clearer communication about biological invasion risks. The framework contextualizes key terms across three domains in invasion science: species invasiveness, risk analysis, and decision support tools. Using both diffusion-of-English and ecology-of-language paradigms, and following a three-step process involving preliminary consensus, AI querying, and ground-truthing with final consensus, we validate the framework in 70 non-English languages which, together with English, have official status in at least one country and collectively cover all 195 countries worldwide. Our findings reveal that while terminology for risk analysis is well established, terminology for species invasiveness and, especially, for decision support tools remains underdeveloped in many languages, hindering effective communication and policy implementation. Our framework underscores the importance of cultural and political neutrality. By promoting clearer risk communication among scientists, policymakers, and the public globally, we aim to reduce policy fragmentation and foster enhanced collaboration in risk mitigation. We recommend expanding multilingual decision support tools to include the full risk analysis process: risk identification, risk assessment, and risk management. This will support intergovernmental mitigation efforts and promote a unified global response to biological invasions.
This paper studies pursuit–evasion differential games and a game with a life line for the case where the inertial movements of the players are implemented using controls subject to repulsive forces. For solving the pursuit problem and the problem with a life line, the main tool remains the parallel pursuit strategy (in short, the Π-strategy). With the help of this Π-strategy, necessary and sufficient conditions for the solvability of the pursuit problem are obtained, and the capture set or the players’ reachability set is constructed. For solving the problem with a life line in favor of the pursuer, a monotone (with respect to set inclusion) decrease over time of the players’ reachability set is proved. In solving the evasion problem, lower bounds for the distances between the players are obtained, and for a game with a life line in this case, a set is constructed that the evading player can reach without being captured, under arbitrary control of the pursuer. The results are illustrated by representative examples.
Developing a robust adsorbent with high capacity, rapid uptake, and strong stability is essential to mitigate the issue of eliminating persistent per- and polyfluoroalkyl substances (PFAS) from aqueous systems. Herein, we introduce the MIL-based LDH composites, namely MIL-101(Fe)-NH2@MgCo-LDH (MIL@MCL), as a promising adsorbent for perfluorooctanoic acid (PFOA) removal. Different LDH loadings were added onto MIL-101(Fe)-NH2, and the composites were characterized to identify the optimal structure for PFAS removal. The optimized composite achieved >98 % of PFOA, PFOS, PFHxS, and PFBS removal. Moreover, the resulting MIL-based LDH composite exhibited the highest adsorption capacity of 747.5 mg g(-1) and rapid uptake of PFOA compared to pristine MIL and LDH. Kinetic and isotherm investigations showed that adsorption was described by the pseudo-second-order and Redlich-Peterson models. With increasing perfluoroalkyl chain length from C4 to C9, removal efficiencies improved from 82.5 % to 98.9 %. The composite sustained >95 % removal in the presence of Cl- and NO3-, whereas stronger competition from F- and SO42- suppressed adsorption. Mechanistic investigations demonstrated that synergistic Lewis acid-base coordination, electrostatic attraction, and hydrophobic/fluorophilic partitioning governed PFOA capture. Furthermore, the composite exhibited excellent reusability of 92 % capacity retained after 5 cycles. In real water matrices, MIL@MCL reduced long-chain PFAS to sub-ng L-1 levels (e.g., 0.28 ng L-1 for PFDA and 0.41 ng L-1 for PFOA), demonstrating its strong affinity and practical applicability. Thus, this study represents the MIL-based LDH for PFAS removal and highlights its potential as promising next-generation adsorbents for practical water treatment applications.
