Nanotechnology for Sustainable Agriculture, Environment, and Human Wellbeing Nanotechnology has rapidly evolved into a cross-cutting platform that supports sustainable agriculture, environmental protection, and human wellbeing. Recent developments show that smart and biocompatible nanomaterials are increasingly integrated into practical systems beyond laboratory settings. In agriculture, nano-enabled fertilizers, nanosensors, and green-synthesized antimicrobial nanocomposites improve nutrient use efficiency, facilitate early pathogen detection, and reduce chemical pesticide dependence, thereby strengthening productivity on marginal soils. Environmental applications demnstrate comparable progress through two-dimensional nanomaterials, nanocomposites synthesized using deep eutectic solvents (DES-mediated nanocomposites), diamond and graphene-derived sensing platforms, and photocatalytic systems for wastewater remediation, pollutant monitoring, and upcycling of plastic and CO 2 into valuable products. Advances in nanomedicine—including transdermal drug delivery patches, near-infrared responsive hydrogels, nanobody-targeted imaging agents, and carbon quantum dots for protein aggregation control—further contribute to the sustainability agenda by improving human health outcomes. The convergence of these technological directions reinforces the "One Health" perspective, where ecosystem quality, food security, and population health are interconnected. Progress in the field will depend on scalable green synthesis routes, long-term toxicity and environmental fate assessments, and the establishment of clear regulatory frameworks. This mini-review summarizes key advances from 2024-2025 and highlights opportunities for nanotechnology to support resilient agriculture, cleaner environments, and healthier societies.

Activity-based approach to predict the effect of solvent composition on the reaction kinetics of hydroformylation • Kinetic models based on thermodynamic activities to predict solvent effects. • PC-SAFT calculation of activity coefficients to account for solvent effects. • Quantum chemical calculations to consider solvent effects. • Activity coefficients of n-alkenes significantly depend on solvent composition. • Prediction and validation of reaction rates for different solvent compositions. Solvent effects on the kinetics of a homogeneously catalyzed reaction were successfully predicted using a thermodynamically consistent, activity-based approach. The methodology was applied to the Rh/BIPHEPHOS-catalyzed hydroformylation of 1-dodecene performed with equimolar CO/H 2 mixtures in different compositions of a non-polar/polar solvent system, specifically decane/ N,N -dimethylformamide. By employing thermodynamic activities in contrast to conventionally used concentrations, the study effectively decouples solvent effects from kinetic parameters. The PC-SAFT equation of state was used to calculate activity coefficients. Intrinsic, solvent-independent kinetic parameters were fitted to the experimental data of one specific decane/DMF solvent composition, demonstrating for the activation energies quantitative agreement with the results of density functional theory (DFT) calculations. The analysis of the activity coefficients of the reactant 1-dodecene revealed a significant influence on both DMF content and temperature. In contrast, the activities of CO and H 2 were confirmed to depend neither on pressure nor on the solvent. Results of quantum chemical calculations performed for the system considered revealed that the impact of solvent composition on activation energies was insignificant. Compared with experimental results, the proposed approach was proven to accurately predict the reaction kinetics over a wide range of decane/DMF solvent compositions. Thus, it minimizes the need for extensive experimental screening and provides an efficient method for optimizing solvent conditions in homogeneously catalyzed reactions.

Metallophilic Non‐van der Waals Roll‐ups Engineered for Long‐Life Metal Batteries Metal hybrid electrodes are promising for high-energy-density batteries owing to their high theoretical capacities. However, their practical employment is hampered by the inherent incompatibility between molten metals and composite materials resulting from the high surface tensions. Herein, unique metallophilic non-van der Waals (non-vdW) roll-ups of transition metal carbides are produced via metal-bonding adjacent atomic layers in scrolled MXenes, featuring a nano-sized hollow structure and abundant surface dangling bonds as well as remarkable thermal stability up to 800 °C. These features enable the formation of chemical bonding and strong capillary forces between the non-vdW roll-ups and molten metals such as Li, Ga, Mg, and their alloys, leading to the unexpected metallophilic property. As a result, the surface tensions of metal-based composites are significantly reduced, facilitating the fabrication of thin metal hybrid foils with high mechanical tensile strengths. For instance, a Mg foil incorporated with non-vdW Al-V<sub>2</sub>CT<sub>x</sub> roll-ups exhibits a high tensile strength up to 204 MPa, ≈2 times that of bare Mg. When employed as an anode in magnesium batteries, the full cell coupled with the Mo<sub>6</sub>S<sub>8</sub> cathode delivers long-term cycling stability with ≈90.0% capacity retention after 500 cycles at 1 C, attributed to the low diffusion resistance of the hybrid electrode. van der Waals force ; Anode ; Dangling bond ; Cathode ; FOIL method ; Metal ; Transition metal ; Fabrication ; Thermal stability MXene and MAX Phase Materials ; Advancements in Battery Materials ; Advanced Battery Materials and Technologies

Boron-Enabled Stereoselective Synthesis of Polysubstituted Housanes The efficient design of (C)­sp 3 -rich molecular scaffolds with defined exit vectors is central to expanding drug-like chemical space. Here, we report a boron-enabled strategy for the synthesis of polysubstituted housanes from nonsymmetrical dienes. A geminal diboron system ensures site-, regio-, and diastereoselectivity in an energy transfer-catalyzed [2 + 2] cycloaddition of nonsymmetrical dienes while also facilitating the mild generation of a cyclobutyl anion that triggers a stereospecific intramolecular annulation via conjugate addition, delivering complex housanes, with three defined exit vectors, in just two steps. Systematic derivatization across all substituents demonstrates the breadth of chemical diversification, while mechanistic and density functional theory (DFT) computational studies reveal the stereoelectronic origins of diastereoselectivity and the counterintuitive electrophile-driven reactivity of the housane framework. This work establishes housanes as stable, derivatizable, and structurally rigid fragments that provide multidirectional exit vectors, offering a powerful platform for the exploration of three-dimensional (3D) chemical space in medicinal chemistry.

Thickness- and gate-tunable ferromagnetism in low-dimensional Fe₃GeTe₂ nanoflakes This study investigates thickness- and gate-dependent magnetism in low-dimensional van der Waals ferromagnet Fe₃GeTe₂ nanoflakes. The objective was to quantify how critical magnetic parameters evolve when approaching the two-dimensional limit and under electrostatic carrier modulation. High-quality single crystals were grown by self-flux, and flakes with thicknesses between 7.5 and 26 nm were isolated, encapsulated with hexagonal boron nitride, and fabricated into Hall-bar devices. Magnetotransport, polar magneto-optical Kerr effect, and SQUID magnetometry were employed to probe Curie temperature, coercive field, anisotropy, anomalous Hall conductivity, and interlayer exchange. The results reveal a systematic reduction of Curie temperature from 206 K at 26 nm to 156 K at 7.5 nm, consistent with finite-size scaling. Coercive field increased nearly threefold across the same thickness range, accompanied by high anisotropy fields of 4–6 T, indicating enhanced surface-driven perpendicular magnetic anisotropy. Anomalous Hall conductivity rose with thickness and was dominated by intrinsic Berry curvature contributions. Magneto-optical measurements confirmed weakening of interlayer exchange coupling from 0.12 to 0.06 mJ·m⁻² as thickness decreased, marking the crossover toward quasi-two-dimensional behavior. Electrostatic gating of intermediate-thickness flakes shifted the Curie temperature by approximately 5 K per 10¹³ cm⁻² carrier density and reduced coercivity by about 10%, demonstrating effective electrical control of itinerant ferromagnetism. These findings establish a coherent picture of how thickness and carrier density tune magnetic order in Fe₃GeTe₂ nanoflakes. The results address the central research problem and highlight pathways for exploiting electrically tunable two-dimensional magnets in low-power spintronic applications.

Tuning the Electrical Conductivity of Bacterial Cellulose Membranes by Multi-Walled Carbon Nanotube Insertion as Bio-Nanocomposite Conductive Materials Bacterial cellulose (BC) obtained from nata-de-coco represents a sustainable biopolymer that offers broad potential as a platform for functional material development. In this work, the electrical performance of BC was improved through the incorporation of multi-walled carbon nanotubes (MWCNTs), which were dispersed in a cetyltrimethylammonium bromide (CTAB) solution prepared at a 1:1 mass ratio. The resulting composite membranes were examined using four-point probe measurements, scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). The electrical conductivity increased from 0.2 S cm⁻¹ to 1.2 S cm⁻¹ as immersion time was extended, reaching an optimum after six days, which was attributed to better nanotube dispersion and alignment inside the cellulose fibril matrix. SEM and thermal analyses confirmed the gradual integration of MWCNTs into the BC framework. The findings demonstrate that adjusting the insertion duration of nanotubes can effectively modulate the electrical properties of BC membranes, supporting their potential as green bio-nanocomposites for emerging energy and electronic technologies.

Redox Behavior and Electrochromism of a Viologen-Based Molten Poly(ionic liquid) We present the synthesis and characterization of a viologen-based molten poly(ionic liquid), VPIL(TFSI), and its application to electrochromic (EC) devices. VPIL(TFSI) was obtained as a highly viscous liquid with a glass transition temperature of −23 °C, enabling its use in a molten state without additional solvent. Electrochemical analysis by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) of neat VPIL(TFSI) revealed a unique conduction mechanism: while ionic conductivity is dominated by the counter-anion (TFSI) migration, charge transport during redox cycling involves electron hopping between viologen units. Diffusion coefficient analysis indicated that electron hopping is slower than counter-anion migration, suggesting that the reorientation of viologen moieties, rather than ion migration, determines the transport kinetics. An EC device was fabricated using an equimolar mixture of VPIL(TFSI) and a ferrocene-based RAIL as cathodic and anodic components, respectively, without any supporting electrolyte. The device exhibited distinct coloration with strong absorption bands at 530 and 890 nm, attributed to π-dimerization of reduced viologen species, along with high contrast and coloration efficiency comparable to theoretical values. These findings demonstrate the potential of molten poly(ionic liquids) as promising redox-active media for solvent-free and durable electrochromic devices.
