Emerging Trends in Liquid Luminescent Solar Concentrators: Progress and Prospects Liquid luminescent solar concentrators (liquid LSCs) have emerged as a promising alternative to conventional solid-state LSCs for enhancing solar energy harvesting. This review focuses primarily on the two major types of LSCs: liquid-based and thin-film-based systems. By comparing their respective advantages and limitations, it aims to identify how specific performance gaps, such as optical efficiency, quantum yield, scalability, recyclability, ease of fabrication, and cost can be addressed by one type over the other. Particular emphasis is placed on liquid LSCs, which, unlike their solid thin-film counterparts, offer unique benefits such as solution-processability, facile large-area coverage, self-healing potential, and material reusability. However, despite these benefits, research in this area remains scarce, with relatively few studies published to date. This review aims to provide a comprehensive overview of the recent developments in liquid LSCs, covering fundamental operating principles, key performance metrics, and major advances in luminescent materials, matrix design, and device architectures. Explored potential applications in sustainable energy systems are also reported. This review concludes by discussing ongoing challenges like stability, leakage, and contamination, and presenting future directions highlighting the promise of this underexplored field.

Kinetically Arrested SERS‐Active Aggregates for Biosensing There is great demand for biosensors capable of long-term, non-invasive monitoring of low analyte concentrations in various biofluids for diagnostics, personalized healthcare, and disease monitoring. However, biofluids present several challenges to biosensor sensing and stability on account of their complex composition and dynamic nature. Surface-enhanced Raman spectroscopy (SERS) offers ultra-high sensitivity, non-destructive, real-time monitoring, and non-invasive detection, ideal for sensing in complex media. Plasmonic gold nanoparticle (AuNP) SERS-active assemblies have been widely explored owning to their biocompatibility and tunable sensitivity based on AuNP morphology. Here, we employ thiolated poly(ethylene glycol) (PEG-SH) to produce kinetically trapped metastable AuNP:cucurbit[7]uril (CB[7]) aggregates containing robust nanogaps (ca. 1 nm), which have previously displayed strong, reproducible SERS signals at low concentrations. The AuNP:CB[7]:PEG aggregates maintain strong SERS-activity, demonstrating low concentration detection of a model Raman reporter and a bioanalyte in a range of biofluids. Moreover, the aggregates are highly tunable through facile modification of the PEG-SH chain length and grafting density and possess an encoded disassembly mechanism within their design highlighting the potential application of these aggregates for non-invasive in vivo long-term monitoring alongside future customized SERS biosensing applications.

This review highlights recent advances in the development of fluorescent antibiotics, focusing on chemical strategies such as click chemistry, amide bond formation, solid-phase peptide synthesis, and epoxy-amine addition. Also, the practical applications of these fluorescent probes, ranging from imaging, rapid detection, and real-time visual tracking of pathogenic bacteria to the detailed study of molecular dynamics at the cellular level are discussed. The opportunity to combine detection and treatment of infectious diseases underscores the significant promise of these probes, particularly in the face of escalating antimicrobial resistance. However, despite the promise, most studies are confined to laboratory settings.

Porous Metallophilic Frameworks Incorporating Metal–Organic Chains as Humidity Sensors Exploring Uranyl Photoluminescence Abstract Luminescent coordination polymers, including metal–organic frameworks, serve as a platform for optical sensing of physical and chemical stimuli, including temperature or pressure for the former, gases, solvent vapors, explosives, toxic species, etc. for the latter. The related materials built of uranyl cations, UO 2 2+ , remain unexplored, despite their tunable photoluminescence. While recently, bimetallic coordination and supramolecular systems built of cyanido metal complexes have proven a successful pathway toward stimuli‐responsive materials, their combination with uranyl species is limited. Here, the construction of novel uranyl‐based systems demonstrating a distinct sensitivity of emission to solvent vapors is reported, which is achieved by generating metal–organic, i.e, uranyl–2,4′‐bipyridine‐ N,N ’‐dioxide, chains that are arranged into a porous supramolecular framework by metallophilic interactions between attached tetracyanidometallates(II), [M II (CN) 4 ] 2− (M II = Pd, 1 ; Pt, 2 ). Both resulting materials reveal reversible single‐crystal‐to‐single‐crystal transformation upon removal of crystallization solvent molecules, which is due to the flexibility of metallophilic interactions forming a porous metallophilic framework resembling MOF‐74. The presence of infinite channels introduces sensing capabilities to water vapors while the emissive character leads to the humidity‐variable emission characteristics, including the strong variation in emission intensity and lifetime. The obtained systems exhibit repeatable adsorption and emission characteristics, meeting the criteria for luminescent sensors.

Sampling of air pollutants by MOFs, COFs, and POFs in needle traps: A systematic review Background: Air pollution poses significant risks to human health. Advanced sorbents such as metal-organic frameworks (MOFs), covalent organic frameworks (COFs), and porous organic frameworks (POFs) offer high sampling efficiency for airborne pollutants. Integrating these materials into needle trap devices (NTDs) provides a solvent-free approach to air monitoring. Methods: A systematic review was conducted using PubMed, Scopus, and Web of Science to identify studies employing MOFs, COFs, and POFs in NTDs for air sampling. Key analytical parameters, including sampling efficiency, desorption conditions, and validation against standard methods (e.g., NIOSH), were assessed. Results: MOF-, COF-, and POF-based NTDs exhibited exceptional pollutant capture efficiency, with detection limits as low as 0.000016 µg/mL (MOFs), 0.0051 µg/mL (PAF-6), and 0.013 µg/mL (COFs) for PAHs, VOCs, and pesticides, respectively. Optimization via response surface methodology (RSM) enhanced sensitivity by 20–40% and reduced relative standard deviations (RSD) to&lt;10%, ensuring high reproducibility. These sorbents demonstrated long-term stability, retaining&gt;95% of analytes over 60 days of storage, and showed strong agreement (R²=0.97–0.99) with standard methods (e.g., NIOSH 5515, 5600). Notably, MOF-based NTDs achieved a broad linear dynamic range (LDR) of 0.00073–12 µg/mL, outperforming traditional sorbents in trace-level detection. Conclusion: MOF-, COF-, and POF-packed NTDs provide an efficient, cost-effective, and eco-friendly solution for air monitoring. Their high sampling capacity and compatibility with analytical methods highlight their potential for broader applications in occupational and environmental health. Further research should enhance sorbent selectivity and regeneration for improved air quality assessments.

Dynamic pathways in energy landscapes guiding supramolecular Janus dendrimer self-assemblies between lamellar and cubic architectures Elaborate kinetic control enables supramolecular self-assemblies to deviate from equilibrium, depicting profound energy landscapes with remarkable structural and functional diversity. Despite this potential, achieving an energy landscape that encompasses lamellar and inverse cubic structures remains a significant challenge, contrasting with the sophisticated structural transformations naturally orchestrated by cellular systems. Here, we present a dynamic and minimalistic Janus dendrimer self-assembly system capable of reversibly transitioning between lamellar vesicles and inverse cubic structures. By exploiting temperature-triggered non-covalent interactions, including OEG interdigitation and hydrogen bonding, conformational flexibility, and molecular packing, we reveal a rich energy landscape featuring diverse assembly pathways spanning lamellar vesicles and inverse cubosomes. Our study not only enriches the structural versatility of Janus dendrimer assemblies but also provides a foundation for advancing supramolecular systems toward applications in biomedicine, catalysis, and beyond.

Monolayer TiS <sub>2</sub> Nanosheets on Au(111)–Structural Characterization and Effect of Edge Stability for Shape Control Transition metal dichalcogenides are promising alternatives to noble metal catalysts, e.g., for (photo-)activation of greenhouse gases or hydrogenations. Herein, a direct synthetic route for 2D TiS<sub>2</sub> nanosheets on Au(111) by titanium deposition in the presence of a mild, organic, non-oxidizing sulfur source is presented. High-resolution scanning tunneling microscopy (STM) is used to gain atomic-level insights into the TiS<sub>2</sub> nanosheet morphology. In contrast to the literature, this protocol gains mostly hexagonal and truncated triangular nanosheets with an increased edge contrast in STM, analog to metallic edge states in MoS<sub>2</sub>. Synchrotron-based photoelectron spectroscopy allows insights into compositional details, specifically to distinguish different S sites on the TiS<sub>2</sub> sheets and other S species on the sample. Further, a minimum size is identified (9 S atoms side length), which underlines the importance of moiré reconstructions for stress relief. The TiS<sub>2</sub> sheets coexist with [Au]Ti<sub>1</sub>S<sub>3</sub> clusters, in which a single gold atom is alloyed into the surface and capped by three S atoms. Together with the finding of a critical sheet size, this points toward on-surface Ostwald ripening as a relevant process in the sheet formation. Ab-initio calculations (density functional theory) underscore that the chemical potential of S is an essential descriptor to maintain shape control.

Design considerations for photoinitiator selection in cell-laden gelatin methacryloyl hydrogels Light-assisted bioprinting of protein-derived hydrogels has been widely used for tissue engineering and regenerative medicine. The practical challenges of the photoinitiators (PIs) are often overlooked in using photo-crosslinkable bioinks for <i>in situ</i> and <i>in vitro</i> applications. A higher concentration of PI is believed to increase the network density of a hydrogel thus reducing its mass transfer capacity, but PI can form reactive oxygen species (ROS) and cause unwanted side reactions around biological compartments. This study systematically investigates the role of ROS generation on mesenchymal stem cells encapsulated in gelatin-methacryloyl hydrogels when using type I PIs-<i>e.g.</i> lithium phenyl(2,4,6-trimethyl-benzoyl)phosphinate and 2-hydroxy-1-(4-hydroxyethyl-phenyl)-2-methyl-1-propanone, and type II PI-<i>e.g.</i> Eosin Y. The results reveal that higher concentrations of type I PIs provide a higher elastic modulus at the expense of enhanced ROS generation and a proportional decrease in viability. We report a novel hydrogel system with minimal PI loading where a reduction in elastic modulus is accompanied by a simultaneous decrease in pore size and ROS level leading to a significant increase in stem cell viability over one week of <i>in vitro</i> culture. In contrast, the type II PI reveals a moderate fluctuation of elastic modulus over a range of PI concentration correlated to fluctuations in ROS generation. Monitoring ROS level variations enables evaluation of each PI's impact on cell response, providing a strategy for the biofabrication of cell-laden constructs. This framework can inform the rational design of photo-crosslinkable hydrogels for light-assisted bioprinting and <i>in situ</i> crosslinking applications in regenerative medicine.

Decorating Ti3C2 MXene Nanosheets with Fe-Nx-C Nanoparticles for Efficient Oxygen Reduction Reaction Finding alternatives to platinum that exhibit high activity, stability, and abundant reserves as oxygen reduction electrocatalysts is crucial for the advancement of fuel cells. In this study, we first mixed FeCl2·4H2O, 1,10-phenanthroline, and Vulcan XC-72, followed by pyrolysis in a nitrogen atmosphere, to obtain FeNC. Subsequently, we combined FeNC with MXene produce FeNC/MXene composites. The FeNC/MXene catalyst achieved a half-wave potential of 0.857 V in an alkaline medium, exhibiting better oxygen reduction reaction (ORR) activity and durability than commercial Pt/C catalysts. The layered structure of MXene endows the material with a high specific surface area and facilitates efficient electron transfer pathways, thereby promoting rapid charge transfer and material diffusion. The cleavage of Ti-C bonds in Ti3C2 at elevated temperatures results in the transformation of MXene into TiO2, where the coexistence of anatase and rutile phases generates a synergistic effect that enhances both the mass transfer rate and the electrical conductivity of the catalytic layer. Additionally, the unique electronic structure of the FeNx sites simultaneously optimizes electrocatalytic activity and stability. Leveraging these structural advantages, the FeNC/MXene composite catalysts demonstrate exceptional catalytic activity and long-term stability in oxygen reduction reactions.
