Flexible phosphonium and sulfonate pair-to-pair self-assembled ionic organic single crystals for iodine capture In this work, four flexible chain phosphonium-based ionic organic single crystals (IOCs) are first facilely prepared by pair-to-pair ionic self-assembly of phosphonium salts and sulfonic acids (salts) under mild conditions. Their structures, morphology, stability, and surface areas are characterized in detail. Featuring a wealth of sulfonate and phenyl groups as powerful active sites for iodine adsorption, these materials exhibit considerable capture capacities. An in-depth investigation of the adsorption mechanism reveals that iodine adsorption on these materials occurs in three distinct states (I<sub>2</sub>, I<sub>3</sub> <sup>-</sup>, and I<sub>5</sub> <sup>-</sup>) and follows a mixed-mode adsorption process, involving both physical and chemical interactions. Consequently, this study not only presents a new kind of single crystalline material based on flexible phosphonium and sulfonic anionic pairs, but also significantly hints at the application possibility of this kind of IOC in some other fields.

Density functional theory insights into the solvent effect on the binding energies of Cd <sup>2+</sup> in functionalized MOFs The clean-up of cadmium-contaminated waters is a significant environmental issue, and metal-organic frameworks (MOFs) have been shown to be effective adsorbents with great potential. Yet, the basic principles driving Cd<sup>2+</sup> binding in multiple solvent environments remain enigmatic and hinder rational adsorbent design. In this work, the solvent effects on the binding energies of Cd<sup>2+</sup>, referring to (M = -NH<sub>2</sub>, -OH, -COOH, and -NO<sub>2</sub>), are systematically investigated using DFT in four solvents (water, ethanol, methanol, and acetonitrile). Using the SMD implicit solvation model and the M06-2X functional with def2-TZVP basis set, we demonstrate that solvent polarity significantly affects binding thermodynamics, with aqueous systems demonstrating 68-72% weaker binding than acetonitrile. With binding energies of -156.8 kcal mol<sup>-1</sup> (water), -187.3 kcal mol<sup>-1</sup> (ethanol), -181.4 kcal mol<sup>-1</sup> (methanol), and -198.5 kcal mol<sup>-1</sup> (acetonitrile), the carboxyl-functionalized MOF exhibits exceptional performance in all solvents. Protic solvents (1.18-1.24|<i>e</i>|) exhibit greater charge transfer than aprotic acetonitrile (0.94-1.08|<i>e</i>|), according to natural bond orbital analysis. This is explained by hydrogen bonding networks stabilizing charge-separated coordination states. Predictive relationships for mixed-solvent industrial wastewater applications are established by the significant linear correlation between binding energies and inverse solvent polarity (<i>R</i> <sup>2</sup> = 0.96-0.98). These results directly address the pressing need for efficient cadmium remediation technologies in a variety of aqueous-organic media by offering crucial theoretical guidance for the design of solvent-adaptive MOF adsorbents optimized for particular industrial effluent compositions.

Anisotropic Growth of 2D Nonlayered α‐Fe <sub>2</sub> O <sub>3</sub> for Artificial Optoelectronic Synapse Abstract Inspired by the human visual system, artificial optoelectronic synaptic devices are capable of performing perception, recognition, and memory tasks in a highly efficient and parallel way. Among the materials explored for constructing these devices, 2D transition metal oxides (TMOs) stand out due to their tunable compositions, exceptional stability, and unique optoelectronic properties. However, challenges such as complex device architectures, compromised material quality, and high energy consumption persist. Herein, the successful growth of 2D nonlayered α‐Fe 2 O 3 nanoflakes is reported via a molecular sieve‐assisted chemical vapor deposition (CVD) method. These nanoflakes, with a minimum thickness of two unit cells, exhibit high crystallinity, n‐type charge carrier transport properties, and response to 450 nm laser illumination. Notably, the charge trapping/de‐trapping at oxygen vacancies (V O ) and the light‐induced ionization of V O contribute to the distinct electron concentration and current hysteresis during cyclic voltage sweeps in the thin α‐Fe 2 O 3 nanoflakes. This mechanism results in a significantly prolonged photocurrent decay, enabling the emulation of biological synaptic behaviors such as excitatory postsynaptic current (EPSC), paired‐pulse facilitation (PPF), short‐term potentiation (STP), and long‐term potentiation (LTP). Combined with the scalability of the CVD process, this work highlights the potential of 2D α‐Fe 2 O 3 for applications in integrated artificial vision systems.

Strong crystalline thermal insulation induced by extended antibonding states Crystalline solids with extreme insulation often exhibit a plateau or even an upward-sloping tail in thermal conductivity above room temperature. Herein, we synthesize a crystalline material AgTl<sub>2</sub>I<sub>3</sub> with an exceptionally low thermal conductivity of 0.21 Wm<sup>-1</sup>K<sup>-1</sup> at 300 K, which continues to decrease to 0.17 Wm<sup>-1</sup>K<sup>-1</sup> at 523 K. We adopt an integrated experimental and theoretical approach to reveal the lattice dynamics and thermal transport properties of AgTl<sub>2</sub>I<sub>3</sub>. Our results suggest that the Ag-I polyhedron enables extended antibonding states to weaken the chemical bonding, fostering strong lattice anharmonicity driven by the rattling vibrations of Ag atoms and causing lattice softening. Experimental measurements further corroborate the large atomic thermal motions and low sound velocity. These features impede particle-like phonon propagation and significantly diminish the contribution of wave-like phonon tunneling. This work highlights a strategy for designing thermal insulating materials by leveraging crystal structure and chemical bonding, providing a pathway for advancing the development of thermal insulators.

Characterising Dissolution Dynamics of Engineered Nanomaterials: Advances in Analytical Techniques and Safety‐by‐Design Engineered Nanomaterials (ENM) have rapidly emerged as vital components in modern technology, most notably as vehicles in vaccine delivery, which highlights their growing potential for interaction with biological and environmental systems. One critical property influencing ENM behavior is dissolution, the release of ions and molecules into surrounding media, which dictates their abundance, fate, and biological response. A decade ago, dissolution was recognised as pivotal in understanding ENM interactions with exposure media and assessing their potential toxicity. Since then, progress in this field has led to a deeper understanding of ENM surface chemistry and transformations, positioning dissolution as a key factor in achieving "Safety-by-Design" (SbD) for sustainable ENM applications. Early dissolution studies relied on batch and flow-through methods, such as dialysis, but recent advances have favored in situ techniques such as single-cell/single-particle inductively coupled plasma mass spectrometry (ICP-MS) and liquid-cell electron microscopy, enabling real-time dissolution measurements. Additionally, computational models can now predict ENM reactivity and stability, enhancing the understanding of dissolution behavior. This perspective critically examines these developments, highlighting computational approaches for their efficiency and scalability, and proposes a roadmap to integrate these insights with SbD goals for safer, sustainable nanotechnology applications.

Natural polyphenols for sustainable active, smart, and intelligent food packaging: a structured narrative review Food packaging offers essential food safety to the consumers. Conventional plastic-based food packaging offers only ordinary physical protection and may sometimes accelerate plastic pollution. Approximately one-third of all packaged foods are known to spoil in the supply chain mainly because of ordinary food packaging. Active, smart, intelligent, and nanocomposite food packaging measures offer many advantages over conventional food packing to retain quality while ensuring extended shelf-life. Natural fruits, vegetables, and tea are abundant source of polyphenols. Notably, recent trends in research demonstrate the utilization of natural polyphenols sourced from food-waste materials for sustainable use in active/smart/intelligent/nanocomposite food packaging. In this narrative review, we explore studies on active, smart, and intelligent food packaging films prepared using natural and food-waste polyphenols. The active packaging films/pads prepared using food-waste polyphenols and fruit polyphenols offer excellent antibacterial, antioxidant, antibrowning, and health-friendly effects. Thus, active, smart, and intelligent packaging materials using natural and food-waste polyphenols help to extend the shelf life of food and ensure minimal wastage of packed food. In addition, some of the active packaging films are edible while some others are biodegradable. In conclusion, the present review is expected to be helpful for promoting more sustainable use of food-waste-polyphenol-based active, smart, and intelligent food packing research.
