Investigation on the fluorescence detection mechanism of NIR fluorescent probes based on intramolecular spiro cyclization The consistency between the calculated optical parameters and experimental data validates the proposed detection mechanism centered on spiro cyclization/ring-opening processes and associated changes in π-electron conjugation. This mechanism clarifies how the structural flexibility of the probes (driven by analyte binding) regulates their fluorescence properties, providing a theoretical basis for the rational design of high-performance NIR-II fluorescent probes with tunable optical responses. Future work may leverage this mechanism to develop probes for a broader range of analytes, further advancing their utility in biological imaging and environmental monitoring.

Data-driven visualization of silica-based nanobiomaterial dynamics for tissue regeneration Over the past two decades, silica-based nanobiomaterials (SNs) have emerged as a promising frontier in regenerative medicine, garnering substantial interest for their potential applications. Despite this growing interest, a notable lack of comprehensive and dynamic analyses remains, examining the evolution, development trends, research hotspots, and prospects of SNs in this field. To address this gap, we systematically analyzed 853 research articles published between 2006 and 2025 in the Science Citation Index Expanded (Web of Science Core Collection). Using bibliometric tools-CiteSpace, VOSviewer, and Biblioshiny-we generated data-driven visualizations to elucidate publication trends, contributions by countries/regions and institutions, journal distributions, research categories, thematic focuses, reference networks, and keyword dynamics. Our findings reveal a rapid acceleration in research output. While China leads in academic output volume, the United States maintains a significant advantage in average citation frequency, highlighting disparities in research impact. Current research hotspots include drug delivery systems, antimicrobial activity, bone regeneration, and wound healing. Keyword burst analysis identifies emerging frontiers such as mesoporous bioactive glass nanoparticles, wound healing, and zinc ion dopants. This study not only maps the trajectory of SNs in regenerative medicine but also discusses critical challenges and future directions, offering valuable insights for advancing the field.

Effect of tara gum and nano-CaCO3 edible coatings on postharvest quality and shelf-life extension of guava (Psidium guajava L.) The use of biodegradable and edible coatings has become an alternative for the preservation of postharvest fruits, replacing traditional plastic. In this work, an active coat based on tara gum, supplemented with nano-CaCO 3 , was developed. The synthesis of nano-CaCO 3 was optimized using design of experiments, reaching the best condition with a flow rate of 0.25 mL·min −1 , a 1:5 ratio of reagents, and a temperature of 17.5 °C, resulting in a hydrodynamic radius of 64.80 ± 7.77 nm. Thus, 0.1%, 0.3%, and 0.5% (w/v) of nano-CaCO 3 were dispersed in the tara gum 1.5% (w/v). All coating conditions were applied to guava fruits. The coated fruits had a decrease in weight loss and firmness with less variation in the fruit peel color. The pH, titratable acidity, soluble solids, and reducing sugars were kept similar, indicating that the coating does not change the physicochemical properties of the guavas. The results show that it is possible to develop a nanotechnological packaging that preserves postharvest guavas, increasing the shelf life of the fruit up to 137.5%.

STUDY OF GRAPHENE COATING EFFECTIVENESS FOR MITIGATING LOW-TEMPERATURE HOT CORROSION IN SS630 STAINLESS STEEL In this work, the hot corrosion behavior of stainless steel 630 (17-4 PH) with and without a graphene nanoplatelet covering is examined during cyclic thermal exposure in both salt-free and salt-laden conditions. Prior to testing, SS 630 specimens were selected due to their exceptional strength and resistance to corrosion and were ultrasonically cleaned, mirror polished and precisely machined. To improve adhesion, a controlled dip coating method was used to apply a stable graphene dispersion made in ethanol, which was then thermally cured. A 1:1 combination of sodium sulfate (Na2SO4) and vanadium pentoxide (V2O5) was utilized to mimic harsh combustion conditions for salt exposure. Three temperatures, 300, 350 and 400 °C, were used for hot corrosion testing with 50 heat cycles per condition. Surface analysis and weight increase measures were used to gauge the extent of deterioration. The findings showed that corrosion rose with temperature, particularly when exposed to salt. The largest weight gain for uncoated specimens in a salt environment was 0.32 g/cm2 at 400 °C. This was considerably lessened by graphene coverings, which decreased the weight growth by up to 52 % in salt-free and 45.6 % in salt-rich environments. Graphene-coated specimens consistently showed 40–55 % less weight increase than uncoated ones across all test conditions, according to comparative analysis. SEM examination confirmed that coated samples had better surface integrity, less oxide spallation, and less scale formation. These results demonstrate graphene’s promise as a strong corrosion barrier for applications involving low temperatures. According to the study, components in heat exchangers, boilers, low-pressure stream turbines and other industrial systems subjected to corrosive and thermal stressors might have their service lives greatly increased by graphene coatings.

Impact of grain boundary segregation on piezoelectric performance of CaBi&lt;sub&gt;2&lt;/sub&gt;Nb&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;9&lt;/sub&gt; high-temperature piezoceramics Grain boundary segregation plays a critical role in determining the properties of polycrystalline materials, yet its influence on piezoelectric performance remains underexplored. In this work, bismuth layer-structured piezoceramic W&lt;sup&gt;6+&lt;/sup&gt;-doped CaBi&lt;sub&gt;2&lt;/sub&gt;Nb&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;9&lt;/sub&gt; (WCBN) was chosen to investigate the effect of grain boundary segregation on the piezoelectric properties through multiscale structural characterization and phase-field simulations. The results reveal that improper grain boundary segregation can induce internal stress fields that restrict domain switching dynamics, leading to deterioration of the piezoelectric response. Therefore, a novel poling process was developed, which effectively alleviated the segregation-induced stress constraints and enhanced the piezoelectric coefficients by 180%. More importantly, optimizing the preparation process significantly enhances the mechanical properties, particularly increasing the fracture toughness of WCBN ceramics to 2.73 MPa m&lt;sup&gt;1/2&lt;/sup&gt;, which is more than twice that of traditional Pb(Zr, Ti)O&lt;sub&gt;3&lt;/sub&gt; piezoceramics. These findings establish direct correlations between grain boundary segregation, internal stress, and domain switching behavior, providing fundamental insights for the design of piezoelectric materials that integrate both high piezoelectric and mechanical properties, which could be greatly beneficial to long-term stable operation in harsh environments with high temperatures and complex vibrations for bismuth layer-structured piezoceramics.

Resolution of Creatinine Interference in Dexamethasone Sodium Phosphate Injectable Preparations: A Validated First-Order Derivative Spectrophotometric Method Using Matrix Matching and Zero-Crossing Point Interpolation Background: The quantification of Dexamethasone Sodium Phosphate (DSP) in injectable formulations is significantly hindered by the spectral overlap of the stabilizer creatinine within the UV region. This study aims to develop a green first-order derivative (D1) spectrophotometric method to resolve this analytical challenge. Methods: Distilled water was utilized as a sustainable solvent, aligning with green chemistry principles. To ensure high specificity, a matrix-matching calibration strategy with a constant 1:2 (w/w) DSP:creatinine mass ratio across the entire concentration range was employed. DSP was determined using the zero-crossing technique, measuring the D1 amplitude at λZC ≅ 231.3 nm, where the creatinine contribution is nullified. Results: Linearity was established for DSP concentrations between 4.0–16.0 μg/mL (R2 &gt; 0.99). Method validation, as per ICH Q2 (R1) guidelines (International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use), demonstrated excellent accuracy (mean recovery of 99.85%) and precision (RSD &lt; 2%). Conclusions: The proposed method offers a rapid, cost-effective, and eco-friendly alternative for the routine quality control of DSP injectables, eliminating the necessity for complex chromatographic separation techniques.

Application of nanoscience and technology for increasing the shelf life of seeds and fruits of horticulture crops The use of nanoscience and technology in horticulture has attracted significant attention due to its potential to enhance the shelf life of seeds and fruits. Nanotechnology-based methods, such as nanocoatings, nanoencapsulation, nanoemulsions and nano-packaging, have shown promising results in preserving the freshness of fruits and seeds by minimizing microbial contamination, reducing post-harvest losses and improving seed viability. Nanomaterials such as silver nanoparticles, titanium dioxide, zinc oxide, chitosan and carbon-based nanostructures exhibit antimicrobial, antioxidant and controlled-release properties, which contribute to extending the storage periods. This review examines the recent advancements in nanotechnology for post-harvest preservation, emphasizing the mechanisms, benefits and challenges associated with these innovative techniques. Biodegradable nanoparticles are emerging as environmentally friendly alternatives to chemical preservatives in food preservation. Additionally, advanced nano biosensors are being developed to measure freshness in real time and detect spoilage at an early stage. Research and policy development are necessary to address issues including cost-effectiveness, regulatory concerns and environmental impacts, despite these encouraging benefits. Furthermore, the environmental and safety concerns related to nanomaterial applications in horticultural products are discussed. Integrating nanotechnology in horticulture presents a sustainable and efficient solution to meet global food security demands by minimizing post-harvest losses and improving crop productivity and food security, making it a crucial area for future innovation and investment.

Charge-Carrier transport simulations in diamond detectors with electric-field-dependent mobility and charge-collection-distance-based trapping Diamond detectors are attractive for operation in harsh radiation environments because they combine radiation tolerance, fast signal formation, and low leakage current. Realistic detector-response simulations require an accurate description of charge-carrier mobility and trapping, which determine both signal amplitude and timing. In this work, we extend \allpix{}, a modular end-to-end detector simulation framework, with diamond-specific transport models. The implementation includes field-dependent mobility parameterizations for electrons and holes and an effective trapping model based on the charge collection distance (CCD), providing a detector-level interface to material quality and radiation-damage measurements. The mobility description is validated in the negligible-trapping limit using single-crystalline CVD diamond by comparing simulated drift velocities and transient-current signals with published reference data. For polycrystalline CVD diamond, the CCD-based trapping model is evaluated using experimentally measured CCD values and compared with laboratory transient-current-technique waveforms. The simulations reproduce the measured drift-velocity behavior in scCVD and the reduced charge collection and degraded transient response observed in pcCVD. The presented implementation enables detector-level studies of charge collection, pulse formation, and timing performance in diamond sensors using experimentally accessible transport and trapping parameters, and provides a practical framework for simulation-driven detector development and radiation-damage studies.

Development of Carvacrol-Loaded Albumin Nanoparticles: Evaluation of Antimicrobial Activity Against Aquaculture Pathogens and Controlled Release Propertiese Pathogens The increasing prevalence of bacterial infections in aquaculture highlights the growing need forenvironmentally friendly and effective antimicrobial strategies. This study aimed to develop and evaluateCarvacrol-loaded human serum albumin nanoparticles (CRV-Al@NPs) as a controlled-release system withantibacterial activity against aquaculture pathogens. CRV-Al@NPs were successfully prepared using amodified desolvation method, achieving high encapsulation efficiency (81.7±2.1%) and loading capacity(56.6±2.3%). The nanoparticles exhibited uniform spherical morphology, narrow size distribution (172 nm,PDI 0.17), and moderate electrostatic stability (zeta potential –27 mV). In vitro release studies demonstratedpH-dependent and controlled release of Carvacrol, with slower release under alkaline conditions, confirmingthat the albumin matrix effectively modulates compound diffusion. Stability tests conducted over 48 h at pH6.5–8.5 showed that the nanoparticles maintained their size, polydispersity, and colloidal stability.Antibacterial activity was evaluated against Aeromonas salmonicida and Listonella anguillarum, yieldinginhibition zones of 17.3 mm and 15.4 mm, and MIC values of 37.5 μg/mL and 18.75 μg/mL, respectively.Blank nanoparticles and solvent controls showed no activity, indicating that the antibacterial effect isattributed to Carvacrol. These findings demonstrate that Carvacrol retains its antibacterial efficacy afterencapsulation and that CRV-Al@NPs can provide controlled and prolonged activity against the targetpathogens. Overall, this study presents a novel nanoparticle system capable of pH-responsive controlledrelease, and the combination of natural antimicrobial compounds with nanoparticle-based delivery offers apromising and environmentally sustainable approach for disease management in aquaculture.

Programmatically Generated Microparticles Using SUEX Dry-Film Epoxy Resist We present a lithographic method for fabricating free-standing microparticles directly from SUEX dry-film epoxy resist. Unlike conventional SU-8 particle fabrication, which requires patterning on solid substrates followed by sacrificial-layer release, our approach eliminates substrate use entirely and produces particles with near 100% yields. The process supports a wide design space of in-plane geometries, including high-aspect-ratio and highly complex shapes. To enable large-scale particle libraries, we integrate the method with the Nazca Python library, allowing programmatic generation of tens of thousands of parametrically defined particle designs. This combination of substrate-free fabrication and automated design provides a scalable route to custom microparticles for materials science, microfluidics, and soft-matter applications.
