Assessment of radiation shielding efficiency in polymeric composites reinforced with natural fibres and multilayered nanoparticles This study describes the development and assessment of natural, polymeric, and hybrid epoxy-based composites that are reinforced with jute mats or polyethylene sheets and contain 25 wt% lead and 25 wt% boron carbide nanoparticles. According to mechanical tests, polymeric composites performed exceptionally well in flexural strength (45.7 ± 1.2 MPa) and impact resistance (1.75 ± 0.26 kJ/m2), while natural composites had the best tensile strength (10.84 ± 1.8 MPa) and hardness (92 ± 1 HRR). Hybrid composites have offered the midway performance rather than the natural and polymeric composites. The radiation shielding efficiency have been evaluated and provided in SI air kerma values in Ir-192 gamma exposure. The natural composites (14.7 mGy) showed better attenuation when compared to polymeric (19.8 mGy) and hybrid composites (21.5 mGy) in comparison with reference CS plate (15.8 mGy). The results showed that the laminate structure is an important part of multifunctional composites. Polymeric composites make things stronger, while natural fibre systems make things harder and better at protecting them.

Data-Driven Prediction of Rebar Corrosion Parameters in Mortar and Simulated Pore Solution Using Optimised Extreme Gradient Boosting Models This study presents two independently optimised Extreme Gradient Boosting (XGBoost) regression models, one for predicting corrosion current density (icorr) and one for predicting corrosion potential (Ecorr) parameters of carbon steel rebar embedded in mortar and immersed in simulated pore solution. An experimental dataset consisting of 216 measurements was curated from a systematic potentiodynamic scan study covering six chloride contamination levels, two carbonation states (non-carbonated and carbonated), four moisture conditions for mortar (65%, 85%, 95% relative humidity, and submerged), and three conditioning durations for simulated pore solution (36 h, 72 h and 20 days). Hyperparameters of the XGBoost models were optimised using a Bayesian optimisation framework with the Tree-structured Parzen Estimator (TPE) sampler over 300 trials. Model performance was assessed using 5-fold cross-validation and a random 80:20 train–test split. The optimised models achieved cross-validation R2 scores of 0.936 and 0.953 for icorr and Ecorr, respectively. On the hold-out test set, R2 values of 0.933 and 0.945 were obtained with test RMSE values of 0.2 log10(µA/cm2) and 41.9 mV, respectively. The contribution of each input feature to model predictions was quantified and visualised using the SHapley Additive exPlanations (SHAP) methodology. SHAP analysis reveals that chloride content has the highest impact on icorr, followed by carbonation state and the low-humidity condition, while for Ecorr, chloride content and the Submerged condition have the greatest impact. An interactive web application was developed using Streamlit, enabling researchers and practitioners to obtain corrosion parameter predictions. The findings provide data-driven insights into the relative importance of environmental factors governing rebar corrosion, with direct implications for the development of accurate corrosion prediction models for reinforced concrete service life assessment.

Flipping the Switch: Next‐Generation Chemo‐Optogenetics for Reversible Control of Biological Systems Chemo‐optogenetic systems, which integrate chemically induced dimerization (CID) with the spatiotemporal precision of light, have emerged as powerful tools for interrogating complex and dynamic biological processes. First‐generation chemo‐optogenetic systems were limited to single activation or deactivation events with light. In contrast, next‐generation chemo‐optogenetic systems now enable reversible, repeatable, and wavelength‐tunable control, greatly enhancing their versatility. This review highlights recent advancements in these technologies, explores their applications in regulating diverse biological functions, and discusses current limitations as well as future directions for next‐generation chemo‐optogenetic systems.

Dual-functional metasurfaces enabling high-efficiency holography and triple-color printing for enhanced optical security platforms Metasurfaces, flat optical devices built from nanoscale structures, offer powerful and precise control over light.They have enabled applications such as structural color printing by manipulating spectral responses and holography through precise phase control.Integrating these functions into a single metasurface has gained interest for compact multifunctional platforms.However, most existing dual-mode designs suffer from low hologram efficiency, limiting their practical applications in multifunctional optical systems.Here, we present dual-functional metasurfaces that simultaneously enable three-color structural printing under white light illumination and high-efficiency holography under coherent light.Our design employs three distinct meta-atoms, composed of single and double nanorods, to achieve independent spectral and phase modulations.The metasurfaces produce three distinct reflective colors of green, brown, and magenta and achieve numerical conversion efficiency up to 90% at the 640 nm wavelength.The fabricated devices successfully display desired structural colors under white light and reconstruct holographic images with high efficiency under coherent illumination.The devices also demonstrate broadband performance for holography across the visible spectrum.These results confirm the effectiveness of our design in achieving independent and efficient control of color and holography within a single metasurface.This multifunctional capability offers strong potential for applications in anti-counterfeiting and compact optical data storage.

Natural Polymers Based Biocompatible Nanomedicines for Targeting Colon Cancer: Prospects and Challenges Natural polymers have gained significant attention as materials for the development of biocompatible nanomedicines, offering promising potential for the targeted treatment of colon cancer. These biopolymers are derived out of renewable resources and possess many beneficial characteristics such as biodegradability, low immunogenicity and easy functionalisation to allow precise targeting, making them highly applicable to nanomedicine applications. They can be used to prepare nanoparticles that can effectively deliver therapeutic agents to tumor sites, improving therapeutic effects and reducing systemic toxicity. In addition, the versatile chemical structures of natural polymers allow conjugation with targeting ligands, which allows increased specificity in colon cancer therapy. However, despite these benefits, there are still a number of challenges in the development and clinical translation of natural polymer-based nanomedicines. The complexity of nanoparticles design, including careful control of particle size, physicochemical properties of the surface, and drug-loading capacity, makes the synthesis process and scale-up difficult. Moreover, the realization of consistent and reproducible production at an industrial level is a significant obstacle. Also, although the phenomenon of enhanced permeability and retention (EPR) increases passive tumour targeting, its heterogeneity in colorectal cancer patients compromises predictability of therapeutic responses, which necessitates individualised treatment plans. The possible cytotoxicity of nanoparticles, especially those with complex structures, highlights the need to have more realistic preclinical models to carefully test safety and therapeutic efficacy. The review provides an in-depth evaluation of the present situation of natural polymer-based nanomedicines in the treatment of colon cancer, their unique properties, therapeutic potential, and the challenges that need to be overcome to achieve clinical success. Novel technologies, including microfluidic systems and individualised treatment plans, are given particular focus as they are likely to reduce these challenges and open the path to safer, more effective, and scalable nanomedicine solutions to colon cancer.

Microstructural Evolution and Physico-Mechanical Response of Cement-Bonded Fiberboards: A Comparative Study on Cement Type and Fiber Ratio This study investigates the interplay between Portland cement strength class (32.5, 42.5, and 52.5) and fiber/cement ratio (ranging from 1/2 to 1/5 by weight) to optimize the physical-mechanical and thermal performance of cement-bonded fiberboards. The experimental data revealed a distinct trade-off: while reducing the fiber content towards a 1/5 ratio significantly improved flexural strength and dimensional stability through matrix densification, it inevitably compromised thermal insulation. Among the binders evaluated, the 42.5 strength class emerged as the most effective option, outperforming the 32.5 class and, notably, offering a more balanced profile than the 52.5 class. The highest stiffness was recorded with the 42.5 cement at a 1/5 ratio (modulus of elasticity (MOE): 5902 ± 532 N/mm2; modulus of rupture (MOR): 12.49 ± 0.6 N/mm2), yielding performance metrics comparable to the 1/4 ratio (MOR: 12.78 N/mm2). Furthermore, this formulation demonstrated superior moisture resistance, achieving water absorption (WA) values as low as 18.9%. Thermal conductivity (TC) measurements at 20 °C confirmed that while fiber-rich mixtures (1/2 ratio) favored insulation, the 42.5 cement at a 1/4 ratio maintained a competitive conductivity value (λ = 0.1625 W/mK), lower than that of the 52.5 grade, thereby striking a critical balance between structural integrity and thermal efficiency. Statistical analyses (Two-way ANOVA, p &lt; 0.05) corroborated the significant influence of both cement type and mix ratio. Microstructural insights from Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) suggest that the superior performance of the 42.5 cement is associated with optimized hydration kinetics and a well-graded particle size distribution (D50 = 14.80 µm), which together facilitated effective fiber encapsulation.

Subcellular nanoparticle trafficking investigated with label-free, live cell imaging Nanoparticle drug delivery systems have significant potential to transform precision medicine due to their ability to encapsulate a wide range of cargo, improve systemic circulation time, and enhance targeted delivery. These delivery properties can be further modified by altering the surface chemistry of the nanoparticle carrier. However, a gap remains in our understanding of the cellular mechanisms underlying nanoparticle uptake, in addition to the subcellular trafficking kinetics. A comprehensive understanding of nanoparticle-cell interactions considering both the nanocarrier and the drug cargo has been challenging, in part due to technological limitations. Here, we present a robust imaging workflow to study long-term dynamics of nanoparticle delivery in live cells. We show that integration of holography and tomography enhances the study of live cells in a label-free environment and can be combined with intermittent fluorescence microscopy to assess nanoparticle uptake and delivery kinetics for up to 30 hours. We also describe a method to quantitatively characterize uptake of a library of fluorescently tagged lipid- and polymer-based nanoformulations without introducing cell or organelle markers. This application of dynamic fluorescent holotomography as a novel method to investigate nanoparticle uptake and cargo delivery highlights the expanding utility of multimodal, label-free, live imaging techniques.

Green Approaches in Forensic Separations—An Overview Green Analytical Chemistry (GAC) provides a framework for reducing hazardous reagents, energy consumption, and waste. The topic has gained momentum across many chemical industries over the past 25 years; however, progress in implementing sustainable methods and conducting greenness assessments within forensic laboratories has been comparatively slow. The purpose of this review is to highlight green approaches to analytical separation methods, including greenness assessment metrics, that have been reported in the literature for forensic chemistry and toxicology applications and to raise awareness of GAC in the forensic field. Recent scientific literature highlights promising advances in greener sample preparation and chromatographic approaches, particularly in forensic toxicology and seized-drug analysis. Emerging trends include the use of green solvents, bio-based and deep eutectic solvent systems, and the rapid expansion of microextraction techniques such as SPME, LPME, MEPS, FPSE, and DLLME, which reduce solvent volumes, minimize waste, and support higher-throughput workflows. Parallel developments in portable and miniaturized chromatographic instrumentation such as miniaturized LC–MS systems with increased detection specificity and Lab-on-a-Chip applications show promise for in situ measurements in the field. Ambient ionization mass spectrometry—in particular, DESI and DART—has had a major impact on forensic chemistry by providing tools for the rapid and direct analysis of chemical compounds in complex matrices with little or no sample preparation. Greenness assessment tools—including AGREE, AGREEprep, Eco-Scale, GAPI, and BAGI—are increasingly applied to evaluate analytical methods in forensic chemistry and toxicology, including those used for novel psychoactive substances. Although many green methodologies are well documented, their routine implementation remains limited. The continued integration of green solvents, microextractions, portable instrumentation, and standardized greenness metrics will be essential for advancing sustainable forensic separations.

The design and product application of ceramics based on magnetic shielding with triply periodic minimal surface structures The design of ceramic Triply Periodic Minimal Surfaces (TPMS) can be applied in the design of multifunctional products. In this study, the TPMS structure of Al2O3, formed through digital light processing (DLP) technology, was primarily tested for its mechanical properties and magnetic shielding performance. Seven types of TPMS structures were designed, among which the Schoen gyroid exhibited the best compressive performance. Schwarz ‘W’ structure was tested and found to have good magnetic shielding characteristics, mainly derived from the reflective absorption within the structure. The magnetic shielding performance can be applied to the customized design and application in a variety of products.
