Hydroxyl-modified chitosan nanofiber beads for sustainable boron removal and environmental applications The removal of boron from wastewater is essential for protecting environmental health and supporting sustainable urbanization by preventing toxic accumulation in ecosystems. Existing adsorption technologies face challenges such as limited capacity, slow kinetics, high regeneration costs, and reduced efficiency due to adsorbent saturation. This study develops an eco-friendly adsorbent (CGCNF beads) by modifying chitosan nanofibers with d-(+)-glucono-1,5-lactone (GL) to enhance boron removal. The adsorbents were characterized by <sup>1</sup>H NMR, Cosy NMR, SEM, BET, TGA, FTIR, and colloidal titration. Notably, the hydroxyl functional groups grafted onto chitosan nanofibers (49.5%) were found to be three times higher than those on chitosan flakes (16.4%). The CGCNF beads followed the Langmuir model and pseudo-second-order model with a maximum boron adsorption capacity of 6.05 mg g<sup>-1</sup>, surpassing commercial Amberlite IRA-743 resin (5.73 mg g<sup>-1</sup>). The adsorption process of CGCNF beads was much faster, reaching equilibrium in 120 minutes, compared to 720 minutes for adsorbent-based chitosan flakes. The adsorption capacity is significantly enhanced by either elevating the pH levels or introducing salts such as NaCl, KCl, CaCl<sub>2</sub>, or MgCl<sub>2</sub>. The beads showed robust regeneration, maintaining 65.1% of their adsorption capacity after 20 cycles. The developed CGCNF beads also demonstrate simultaneous high-efficiency removal of B(iii) and As(iii) ions from local wet flue gas desulfurization (FGD) wastewater at rates of 94.5% and 100%, respectively, providing a sustainable solution for wastewater contamination.

Sustainable Uranium Extraction via Reversible Uranyl Carbonate Capture‐Release Cycling Stemming from Weak Interaction with Self‐Supporting Covalent Organic Frameworks Extracting abundant uranium resources from the ocean would contribute greatly to the sustainable development of nuclear energy. In this work, it is found that the imine N, phenol-bidentate chelation groups from imine-Covalent-Organic Frameworks (COFs) are superior sites for the weak complexation with uranyl carbonate species. The surprisingly low binding energy of -13.36 kcal mol<sup>-1</sup> originating from the weak coordination bond and hydrogen bond benefits to the readily spontaneous decomplexation of the chelated uranyl carbonate species by CO<sub>3</sub> <sup>2-</sup> ions. Through the rational design of three COFs with uniform imine N, phenol-bidentate sites but varied amine monomer geometry, i.e., pyrene COF (Py-COF), 1,3,5-Triazine COF (TTA-COF) and porphyrin COF (TAPP-COF), it's found that the abundantly available imine N, phenol-bidentate sites ensured by the high specific surface area and strong hydrophilicity of Py-COF and TTA-COF result in the highly reversible uranyl capture-release during the cycled extraction of uranyl carbonate from seawater and mild elution with 2.0 mM Na<sub>2</sub>CO<sub>3</sub> solution. With the 3.0 × 3.0 cm<sup>2</sup> self-supported plate fabricated by Py-COF growth on carbon cloth, a record high uranium extraction capacity of 45 mg g<sup>-1</sup> (i.e., 3.0 mg g<sup>-1</sup> day<sup>-1</sup>) from seawater is achieved within 15 days' capture-release cycles.

Antibacterial and antibiofilm properties of silver nanoparticles synthesized using Carthamus tinctorius extract against various multidrug-resistant bacterial strains The flower extract of Carthamus tinctorius has been used in the synthesis of silver nanoparticles (AgNPs) and exhibited positive results in biomedical applications, specifically antibacterial and antibiofilm activity. The objective of this research was to design a greener and more effective approach toward the synthesis of AgNPs as well as assess multidrug-resistant biofilm-forming bacteria’s antimicrobial activity. Different techniques of characterization like UV–visible spectroscopy, SEM, TEM, FTIR, and EDX confirmed that the spherical-shaped AgNPs, which were successfully biosynthesized in the size range of 20–60 nm. A peak in the UV–visible spectrum was seen at around 417 nm, indicating the formation of the AgNPs. The antimicrobial effect of the biosynthesized AgNPs was examined against Staphylococcus haemolyticus, Escherichia coli, Klebsiella pneumoniae, and Acinetobacter baumannii in dilutions of 100–6.25 µg/mL. The results showed that the inhibition was dose-dependent, with the greatest level of inhibition seen at 100 µg/mL. The largest inhibition zones were demonstrated in E. coli and A. baumannii cultures at the values of 16.66 mm and 16.33 mm, respectively. For all strains tested, the minimum inhibitory concentration and the minimum bactericidal concentration were determined at 6.25 µg/mL. Moreover, subMIC concentrations of AgNPs showed high antibiofilm activity, confirming the use of AgNPs as antibiofilm agents. These results propose further usage of AgNPs in biotechnology and pharmacology as a bioactive agent against bacterial infection, biofilms, and drug-resistant bacteria. The usefulness of C. tinctorius AgNPs in the development of antimicrobial therapies is made apparent due to the studies.

Confining Asymmetrically Coordinated Cobalt Single‐Atoms/Clusters on Holey MXene for Ultrafast Fenton‐Like Catalysis Developing single-atom catalysts (SACs) with asymmetric coordination configurations is essential for enhancing peroxymonosulfate (PMS) activation in Fenton-like reactions. However, precisely regulating the electronic structure and coordination environment of metal centers to further improve activation kinetics remains a key challenge. Herein, we designed asymmetric CoN<sub>1</sub>O<sub>2</sub> single atoms (SAs) sites and Co nanoclusters (NCs) that were spatially confined in highly graphitized carbon layers and supported on holey MXene nanosheet (Co<sub>SA-NC</sub>/H<sub>20</sub>MX) via a dual-coordination microenvironment strategy. The Co<sub>SA-NC</sub>/H<sub>20</sub>MX catalyst demonstrated exceptional performance on bisphenol A (BPA) removal, achieving a corrected rate constant (k<sub>value</sub>) of 2750 min<sup>-1</sup> M<sup>-1</sup> and a total organic carbon removal efficiency of 78.2%. Mechanistic studies revealed that BPA removal was dominated by a nonradical electron transfer process (ETP, ∼100%), which facilitated rapid polymerization of BPA. Density functional theory calculations demonstrated that Co NCs synergistically enhanced the ability of asymmetric CoN<sub>1</sub>O<sub>2</sub> SAs sites to adsorb and activate PMS, significantly accelerating interfacial charge transfer. Furthermore, a catalytic membrane fabricated by crosslinking of Co<sub>SA-NC</sub>/H<sub>20</sub>MX and graphene achieved 100% BPA removal in single-pass mode with a hydraulic retention time of just 40 ms over 24 h of continuous operation. This work provides new insights into designing high-performance catalysts for pollutant removal via ETP-driven polymerization pathways.

It explores some similarities and differences in nanomaterial safety compared to general chemical safety. The paper provides an overview of the encountered challenges and how far they have been resolved, as well as information on how different countries' legislators have addressed nanomaterials, including safety assessment in (new) legislation. Challenges arose due to the unique physico-chemical properties of some nanomaterials and included the lack of i) a regulatory definition, ii) applicable regulatory test methods, including methods for physico-chemical characterization and for ecotoxicological effects, as well as sample preparation and dosimetry, iii) assessment and modelling of human, especially occupational, and environmental exposure to nanomaterials, iv) quantification of nanomaterial in complex media, v) systems for collecting the data generated and ensuring FAIR (Findable, Accessible, Interoperable and Re-usable) and quality data, vi) reference nanomaterials, and vii) a frame for nanotechnology governance. The paper highlights the role of the Organisation for Economic Co-operation and Development (OECD) in building a global, regulatory understanding of nanotechnology and nanomaterials, as well as the OECD's achievements of developing nano-specific test guidelines. The paper identifies areas, such as alternative test methods, availability of reference nanomaterials, comparable data and FAIR data, analytical tools for quantifying nanomaterials in (complex) matrices that are still under-addressed. It gives a wider perspective of Governance of Advanced Materials including nanomaterials, also illustrated by carbon nanotubes used in batteries for electric vehicles, to also aid their commercialization.

Visible‐Light‐Driven Multifunctional Luminogens With More Than 150 Nm Absorption Band Separation for Dynamic Information Encryption ABSTRACT Information security protection has become a fundamental issue in the human life, national security, and social stability, which is enabled through the use of multi‐responsive materials. Ideal multi‐responsive materials are operated with visible to near infrared light, exhibit large separation of absorption bands, and are functional by isomerization, posing an unmet challenge. Here, a series of visible‐light‐operated molecular photoswitches, ( E )‐1‐acetyl‐2‐((4‐(diphenylamino) phenyl) imino) indolin‐3‐one, and its derivatives ( PIO‐01/02/03/04/05 ), featuring near‐infrared second aggregation‐induced emission (AIE) and impressive acid/base‐driven switching, are constructed via twisted intramolecular charge transfer (TICT) and subsequent E / Z isomerization strategies. In addition, protonation not only endows these molecules with large separation (Δ λ max ) of over 100 nm, but also can be used as second independent input altering the light response. Based on calculation studies and advanced spectroscopic techniques, we provide the intricate interplay of the switching behavior of PIO‐01/02/03/04/05 on their photochemical properties. The optimized compound PIO‐01 shows significant applications in multi‐color, multi‐patterning display, transient information recording and erasing, and dual‐mode encryption‐decryption with ternary code.

High-Efficiency and High-Capacity Aqueous Electrochromic Energy Storage Devices Enabled by Decoupled Titanium Oxide/Viologen Derivative Hybrid Materials The integration of electrochromism and energy storage within a single platform marks a pioneering approach to multifunctional electronics. However, achieving electrochromic energy storage devices (EESDs) that exhibit both high coloration efficiency and substantial energy capacity remains a formidable challenge, primarily due to the inherent trade-off between these 2 functionalities. Herein, we propose a distinctive strategy for the fabrication of EESDs using a chemically bonded titanium oxide (TiO<sub>2</sub>)/viologen derivative (<b>TGP</b>) hybrid material, leveraging their decoupled electrochromic and energy storage mechanisms. The resulting EESDs demonstrate a remarkable coloration efficiency of 512.93 cm<sup>2</sup>/C and an impressive areal capacity of 62.2 mAh/m<sup>2</sup>. By employing molecular engineering, we effectively reduce the bandgap and mitigated radical dimerization of the viologen derivative, resulting in a highly saturated magenta-colored state with exceptional stability. The device retained its performance after 3,000 electrochemical cycles in environmentally benign aqueous electrolytes. Furthermore, integration with a counter Zn anode effectively enhances energy utilization efficiency through an energy retrieval process. This approach paves the way for the development of EESDs using hybrid materials, holding great potential to propel advancements in the field of visual energy storage.
