The Synthesis of Ru–Co–Oxalate MOFs for an Electrochemiluminescent Glyphosate Sensor Cobalt-ruthenium bypiridine-oxalate metal-organic frameworks (MOFs) were synthesized via a solvothermal method with a custom-designed reactor that permits stirring, which can result in changes in the morphology of the structures. In this work, we performed a morphological and structural study of MOFs with varying tris(2,2,bipyridyl) and diclororuthenium(II) hexahydrate (Ru(bpy)32+) concentrations, demonstrating changes in the size of the MOFs, and these MOFs were used as the luminescent materials in an electrochemiluminescent (ECL) system for glyphosate (Gly) detection, which acts as a coreactant in the light emission of Ru(bpy)32+. Gly is the most commonly used herbicide worldwide, and our system has a calibration curve range of 10-70 ppm, with a detection limit of 7.6 ppm.

SERS and SEF with enhancement in nanogaps: from fabrication to biosensing This review surveys SERS and SEF spectroscopies, with a spotlight on the correlation between nanogap fabrication techniques and subsequent applications of those nanogaps in biosensing. In the last several decades, the development of new nanofabrication techniques and novel applications substantially increased the importance of these spectroscopic techniques for biosensing. The cornerstone of this development is the application and control of nanogaps between nanoparticles and nanostructures. Nanogaps are important since they may be responsible for the biggest portion of signal enhancement in SERS and SEF. This review summarizes and provides insights into the theory behind nanogap enhancement, nanogap fabrication, and its applications in direct and indirect biosensing. The theoretical part includes studies on the origin of nanogap enhancement and its dependence on gap distance and agglomeration. Next, the review presents and compares structured and unstructured fabrication techniques with a few dozen examples tabulated with their figures of merit, like the enhancement factor (EF) and limit of detection (LOD). In total, 50 SERS-based and 26 SEF-based articles were tabulated, whereas 38 papers were classified based on the synthesis method and based on the EF and median LOD values calculated for Electron Beam Lithography (EBL) and Template-Assisted (TA) prepared substrates that were no more than one order of magnitude better or about the same as those for other fabrication methods (median 1 × 10<sup>-10</sup> and 8 × 10<sup>-10</sup> M for EBL and TA, respectively, <i>vs.</i> median 4 × 10<sup>-8</sup> and 1 × 10<sup>-9</sup> M for nanosphere lithography (NSL) and Self-Assembly (SA), respectively). The median EF for substrates fabricated with EBL, NSL, and TA methods (4.6 × 10<sup>8</sup>, 1.0 × 10<sup>8,</sup> and 1.4 × 10<sup>8</sup>) demonstrates only a moderate advantage over the SA technique, with a median EF of 0.3 × 10<sup>8</sup>. However, unstructured nanofabrication techniques like self-assembly have a more affordable price, lower complexity, and better scalability. Therefore, SA can easily compete with ordered nanofabrication techniques. In addition, this review also highlights the applications of nanogaps in label-free detection and biomarker detection. Finally, this review highlights applications of nanogap enhancement in SEF and draws conclusions on the current state of nanogap research and its future.

Skin-replaceable antifouling cellulose ceramic membranes from jute agro-waste for sustainable and efficient oily wastewater treatment Abstract Oily wastewater presents a serious environmental challenge, demanding sustainable and regenerative membrane technologies. Here, we report a green and scalable method for fabricating skin-replaceable cellulose membranes (SRC-M) from jute agro-waste, using a NaOH/urea activation route and argon-pressurized deposition onto ceramic supports. The resulting Cellulose II -based asymmetric membranes exhibit high water flux (~470 L m⁻²h⁻¹) and &gt;98% oil rejection across various emulsions. Notably, the membrane’s surface can be fully renewed via ultrasonication, restoring &gt;99% of the original flux after 16 fouling cycles. Density functional theory (DFT) calculations confirm the thermodynamic stability (ΔG = -0.162 eV) and low kinetic barrier (0.46 eV) of urea adsorption on cellulose, supporting the dissolution mechanism and regeneration behavior. This biodegradable, self-renewable membrane system offers a robust, circular solution for long-term oily wastewater remediation and aligns with green chemistry principles.

Microbial response and resistance mechanisms against diverse anthropogenic pollutants Anthropogenic activity, driven by industrialization, agricultural practices, and waste disposal, has emerged as a predominant contributing factor to environmental pollution. These activities release substantial amounts of toxic pollutants into the environment, such as heavy metals, organic pollutants, microplastics, and nanomaterials, adversely affecting various ecosystems. These toxic substances can exert considerable stress on various microorganisms, including bacteria, fungi, and microalgae. The impact of anthropogenic pollutants on microorganisms is a nascent area of study, particularly as environmental stressors continue to increase in both quantity and complexity. This review aims to enhance our understanding of how microorganisms (bacteria, microalgae, and fungi) respond to the anthropogenic pollutants including heavy metals, organic pollutants such as polycyclic aromatic hydrocarbons (PAHs), nanomaterials and microplastics. It explores the toxic effects of these pollutants on diverse microbial species. Furthermore, the review covers studies that examine the molecular mechanisms underlying microbial resistance both through natural resistance processes and adaptive laboratory evolution or evolutionary engineering strategies. The review also highlights how omics technologies such as genomics, transcriptomics, proteomics and metabolomics reveal conserved and unique molecular mechanisms to gain insight into the pollutant-specific and organism-specific adaptation strategies. Nevertheless, limitations in community-level multi-omics studies, the relatively limited data on fungi, and the challenges associated with studying mixed cultures hinder a comprehensive understanding of microbial response and resistance mechanisms to anthropogenic pollutants. Addressing these gaps will be pivotal in leveraging the molecular mechanisms to guide the development of novel strategies to obtain pollutant-tolerant strains for bioremediation, bio-monitoring, and synthetic biology applications.

Exsolution synthesis of ferroelectric bilayer MoS <sub>2</sub> in particulate systems as encapsulating chainmail cocatalysts While two-dimensional (2D) ferroelectrics in the form of films have proven their potential in manipulating charge carrier dynamics across diverse systems, the synthesis and application of 2D ferroelectrics in particulate scenarios remain largely unexplored. Fundamental obstacles persist in achieving and maintaining stable ferroelectric ordering within nanoscale domains. Herein, we report a strategy for the controlled exsolution growth of a robust ferroelectric MoS<sub>2</sub> bilayer, which self-assembles into a chainmail architecture that uniformly encapsulates 80 nm CdS nanoparticles. The emergence of ferroelectricity in the MoS<sub>2</sub> bilayer originates from asymmetric lattice contraction, where the inner layer undergoes a 1.51% compressive strain relative to the outer layer.&nbsp;This built-in polarization gradient substantially enhances the vertical (out-of-plane) migration of photoexcited electrons within the MoS<sub>2</sub> structure, as unambiguously evidenced by angle-resolved THz emission spectroscopy. When employed as a cocatalyst, the ferroelectric MoS<sub>2</sub> bilayer remarkably boosts the extraction efficiency of visible-light-generated electrons, achieving an 8.6-fold enhancement in photocatalytic hydrogen production compared to conventional non-ferroelectric analogues. This breakthrough not only advances cocatalyst design principles but also expands the functional landscape of ferroelectric materials in energy conversion technologies.

Comprehensive experimental and theoretical investigations of novel triazine Schiff base metal complexes: spectroscopic, electrochemical, DNA interaction, in vitro cytotoxicity, antimicrobial, and in silico studies The increasing resistance of bacteria and cancer to present treatments is a clinical and laboratory concern. In this study, a novel Schiff base ligand (HL) was synthesized in this work through a solvent-free method, involving the reaction of 2,4-diamino-6-phenyl-1,3,5-triazine with 2-hydroxy-1-naphthaldehyde under mild and eco-friendly conditions. The Ni(II) and Zn(II) complexes were then synthesized and confirmed by different spectroscopic and analytical methods. The results suggest that both complexes have an octahedral geometry, in good agreement with the computational findings. The binding mood of these compounds with CT-DNA was examined using cyclic voltammetry and UV-vis spectroscopy, which revealed a partial intercalation mode. The findings demonstrated strong DNA-binding affinity with binding constants (K<sub>b</sub>) of 2.51 × 10<sup>5</sup> and 5.69 Χ 10<sup>5</sup> M<sup>- 1</sup> for NiL<sub>2</sub> and ZnL<sub>2</sub> complexes, respectively. The calculated free energy (ΔG) values confirmed that these interactions with DNA are strong and spontaneous. Additionally, the compounds' anticancer efficacy was tested against HepG-2 liver cancer cells. IC<sub>50</sub> values for HL, NiL<sub>2</sub>, and ZnL<sub>2</sub> were calculated and determined to be (94.10, 51.08, 43.94) µg/mL. This shows that these complexes can preferentially treat liver cancer. The tested microorganisms demonstrated better response to metal complexes compared to the Schiff base ligand. Finally, molecular docking studies were performed to determine the binding interactions and affinities of the prepared compounds with the active site of the receptors associated with liver cancer (5A19) and A. flavus (8HBS). The study revealed adding metal ions considerably raised molecular affinities, and the binding potency sequence was ZnL<sub>2</sub>> NiL<sub>2</sub> > HL ligand. According to experimental and theoretical evidence, the novel prepared ligand and its metal complexes have great promise as multifunctional bioactive agents, enabling additional pharmacological and biological applications.

Effect of reduced graphene oxide addition on corrosion resistance and magnetic properties of sintered NdFeB magnets Neodymium–Iron–Boron (NdFeB) permanent magnets are indispensable in energy technologies such as wind turbines, electric vehicles, and robotics, but their processing is hindered by spontaneous powder ignition and severe corrosion susceptibility. Here, we demonstrate that incorporating 0.02 wt% reduced graphene oxide (rGO) during mechanical milling enables safe powder handling in ambient conditions without inert atmospheres, while simultaneously enhancing functional performance. Milling time was found to be critical: at 30 min, sintered magnets achieved remanence of 1.11 T, coercivity of 794 kA·m⁻¹, and a maximum energy product of 242 kJ·m⁻³, values comparable to commercial N35 magnets without heavy rare-earth additions. Electrochemical impedance spectroscopy revealed corrosion resistance up to two orders of magnitude higher than values typically reported for coated NdFeB magnets. Structural, electrochemical, and depth-profiling analyses confirmed that rGO acts as both a solid lubricant and encapsulating barrier, balancing grain refinement, oxidation suppression, and interfacial stabilization. This work establishes rGO-assisted processing as a scalable, sustainable, and cost-effective pathway to high-performance NdFeB magnets for next-generation energy conversion and storage systems.

Superhydrophobic, active anti-corrosion, and solar anti-icing coating with fast self-healing properties Corrosion and icing considerably threaten the service safety of magnesium (Mg) alloys in aerospace and transportation industries. Although superhydrophobic coatings offer effective anti-corrosion and anti-icing functions, yet they are limited by the susceptibility of coatings to failure due to physical damage or the capillary condensation phenomenon. Herein, a multifunctional integrated coating is reported, which endows the coated Mg alloys with excellent superhydrophobicity, active anti-corrosion performances, anti-icing properties, and fast self-healing capabilities (SAAS). The experimental and theoretical results reveal that the layered double hydroxide (LDH) modified and intercalated with sodium laurate (La) acts as nanoreservoirs, which releases La corrosion inhibitors through an anion-exchange process to effectively retard corrosion. Based on the incorporation of MXene, the SAAS coating reveals full-spectrum high absorption and efficient photo-thermal conversion, and meanwhile causes a 61 ℃ surface temperature under 1.0 sun illumination. This photothermal effect effectively prevents the adhesion and accumulation of supercooled droplets. Furthermore, near-infrared (NIR) irradiation induces macromolecular chains migration and phase transition, enabling fast self-healing of coating damage. This study not only provides a novel strategy for enhancing the ability of aircraft skins but also offers new insights into the design of multifunctional coatings.

AC frequency effects on high-throughput electrospinning for nanofibre production Alternating current electrospinning (ACES) is emerging as a promising approach for industrial scale nanofibre production, offering the potential for higher throughput and energy efficiency compared to conventional direct current methods. This study presents a series of experiments conducted with a wire-type electrode system, aiming to evaluate the influence of key process parameters, namely alternating field frequency, applied voltage, current limitation, and wire speed-on both the productivity and quality of nanofibrous layers produced from polymer solutions. The results show that an appropriate combination of these parameters significantly enhances both areal weight (GSM) and productivity, while also identifying technological limits related to power supply performance. Furthermore, the effects of these parameters on fibre diameter and the overall quality of the nanofibrous structure are examined. These findings confirm the strong potential of ACES with wire-type electrodes for advancing continuous nanofibre production on an industrial scale, while also revealing critical technological constraints related to power-supply performance and jet stability. The insights gained provide an important foundation for the design of next-generation production lines with higher capacity, improved process stability, and enhanced energy efficiency, moving ACES closer to widespread industrial deployment.
