MnO2-Modified Carboxylated Graphene Oxide Nanocomposite for the Effective Extraction of Organochlorine Pesticides from Environmental Water Samples A manganese dioxide-modified carboxylated graphene oxide (MnO<sub>2</sub>@CGO) nanocomposite was fabricated and utilized as a solid nanosorbent for extracting six organochlorine pesticides from environmental water samples. The target compounds, Hexachlorobenzene (HCB), β-Hexachlorocyclohexane (β-HCH), Heptachlor, Aldrin, Dieldrin, and o,p-Dichlorodiphenyltrichloroethane (o,p-DDT), were determined by micro-solid phase extraction (µ-SPE) coupled with gas chromatography-mass spectrometry (GC-MS) in selective ion monitoring mode. Key experimental factors influencing the extraction performance, such as sample pH, sorbent dosage, type and volume of eluting solvent, and time for desorption, were systematically optimized. Under the optimized conditions, the method showed good linearity (<i>R</i><sup>2</sup> = 0.998-1.000) within the concentration range of 0.1-5 ng L<sup>-1</sup>. The developed procedure was successfully applied to Nile River, agricultural wastewater, and groundwater samples, achieving recoveries between 87.1% and 101.2% with RSDs below 4.0%. The detection limits were 0.005-0.010 mg L<sup>-1</sup> at a signal-to-noise ratio of 3.0. Overall, the MnO<sub>2</sub>@CGO-based µ-SPE method offers a sensitive, reliable, and straightforward approach for monitoring trace levels of organochlorine pesticides in environmental waters.

Palm oil quality detection using optical fiber sensor based on evanescent absorption Palm oil is a major contributor to the economy, especially in regions like Riau, Indonesia, where it accounts for a significant portion of the Gross Domestic Product (GDP) and national crude palm oil (CPO) production. However, the rising demand for palm oil has led to unstable prices and health concerns, particularly when the oil is reused multiple times. Repeated use of palm oil can increase the risk of health issues such as coronary heart disease and cancer due to the presence of saturated fats and carcinogenic compounds. To address these concerns, the study explores methods to assess palm oil quality, specifically using a fiber optic sensor-based evanescent absorption technique. This method detects changes in the oil by measuring the concentration of substances on the sensor surface without damaging the sample. It operates with high sensitivity, detecting even small changes in the refractive index. Machine learning, particularly Convolutional Neural Networks (CNNs), is used to automate analyzing images and detecting patterns related to palm oil quality. The study being summarized focuses on detecting the quality of palm oil from five different brands of cooking oil in Indonesia. The detection device uses the evanescent absorption method, measuring the voltage of the optical signal converted by a photodiode. The study found that the ratio of initial to measured voltage indicates changes in turbidity and refractive index, which increase as the oil is reused. Among the brands tested, Brand B showed the highest ratio after three uses and a high sensitivity, which is 0.456, indicating it becomes turbid quickly. Brand C has a response time of 67–115 seconds, suggesting it could be reused more times without significant degradation Evanescent wave ; Palm oil ; Absorption (acoustics) ; Palm ; Materials science ; Quality (philosophy) ; Optics ; Optoelectronics ; Environmental science ; Physics ; Composite material Spectroscopy and Chemometric Analyses ; Spectroscopy Techniques in Biomedical and Chemical Research ; Industrial Vision Systems and Defect Detection

“Turn on” fluorescence sensors sensitive to volatile organic solvents/plasticizers -perspective and challenges Organic liquids immiscible with water, such as volatile organic compounds (VOCs) and plasticizers are widespread harmful environmental pollutants, which have long been considered a risk factor for chronic diseases in humans. VOCs or plasticizers in the outdoor environment largely originate from industrial manufacturing, combustion and leakage of transportation fuels, and biological metabolism. Consequently, in order to protect the environment and human health, there is an urgent need for point-of-need sensors for VOCs as well as plasticizer detection. Fluorimetric sensors are emerging attractive tool for monitoring concentration changes of these analytes in environmental samples, that can reduce need for advanced, instrumental methodologies. Various fluorescence-based strategies have already been demonstrated, with turn-on fluorescence approaches being particularly promising. These strategies are based on the interaction of fluorometric dyes or conjugated polymers embedded in polymeric matrices with the target analytes. The proposed approaches show great potential for real-time monitoring of hazardous pollutants in environmental applications, offering cost-efficient, simple, and portable alternatives to conventional analytical techniques. However, it is worth emphasizing that despite the great variety of research topics, the current state of knowledge does not exhaust this field, and many challenges still remain to be overcome.

Phase Separation Challenges in Borosilicate Nuclear Glasses and Strategies for Vitrification Improvement This review highlights three main topics: advancements in vitrification technology and associated issues like melter corrosion in global facilities, the chemistry and networking of glassy and frit forms of waste, and improvements in vitrified structures that enhance the properties of glass formulations. Borosilicate glass formulations offer various technical advantages for nuclear waste management, including effective bonding with fission products and actinides, resistance to radiation, simple and safe technology, and low leaching tendencies in aqueous environments. The maximum results indicate that the vitrification facility in Tarapur, India, 43.8% waste loadings with 6.4% B2O3 in the glass composition, while Savannah River Site in the USA processes waste loadings of up to 50 wt% with 6% B2O3 in the glass composition. In the IAEA-TECDOC, it is stated that considering spent fuel borosilicate glasses are suitable matrices for the immobilising up to 13 wt % of UO2 or 6 wt % of PuO2. However, borosilicate glasses may face issues when the molybdenum ratio in the waste exceeds certain limits, potentially leading to phase separation in the vitrified network. This review covers the importance of waste management policies and provides a historical overview of nuclear waste glass in different countries.

Corn Starch as Eco-friendly Bioplastic and the Thermodynamic and Kinetic Analysis The study's goal is to prepare bioplastic by corn starch environmentally favorable. Corn Water, gelatin, glycerin, a food coloring coconut oil, and cotton were used to make bioplastic. The data demonstrate that bioplastic is biodegradable, with an average weight loss of 57.9%. It was partially soluble in ethanol and water but totally soluble in HCl. Swelling test showed no change when immersed in chloroform, but a slight change in water. It degrades more quickly as temperatures rise. The thermodynamic parameters results that the activation energy ΔEa was 36.5 Jmol-1,the positive values of Gibbs energy, entropy ΔS had suggesting non-spontaneous and less organized structure behavior and a negative ΔH value indicating exothermic nature.The rate of kinetic rises as the starch concentration increased. The manufactured bioplastic possesses features such as minimum swelling and is insoluble in water. Corn starch will be making it commercially feasible and a renewable resource.

Mechanistic Insights into Corrosion and Protective Coating Performance of X80 Pipeline Steel in Xinjiang’s Cyclic Freeze–Thaw Saline Soil Environments This study systematically investigated the corrosion evolution and protective mechanisms of X80 pipeline steel in Xinjiang’s saline soil environments under freeze–thaw cycling conditions. Combining regional soil characterization with laboratory-constructed corrosion systems, we employed electrochemical impedance spectroscopy, potentiodynamic polarization, and surface analytical techniques to quantify temporal–spatial corrosion behavior across 30 freeze–thaw cycles. Experimental results revealed a distinctive corrosion resistance pattern: initial improvement (cycles 1–10) attributed to protective oxide layer formation, followed by accelerated degradation (cycles 10–30) due to microcrack propagation and chloride accumulation. Synchrotron X-ray diffraction analyses identified sulfate–chloride ion synergism as the primary driver of localized corrosion disparities in heterogeneous soil matrices. A comparative evaluation of asphalt-coated specimens demonstrated a 62%–89% corrosion rate reduction, with effectiveness directly correlating with coating integrity and thickness (200–500 μm range). Molecular dynamics simulations using Materials Studio revealed atomic-scale ion transport dynamics at coating–substrate interfaces, showing preferential Cl− permeation through coating defects. These multiscale findings establish quantitative relationships between environmental stressors, coating parameters, and corrosion kinetics, providing a mechanistic framework for optimizing protective coatings in cold-region pipeline applications.

Green Synthesis and Process Optimization of Zinc Oxide Nanoparticles Using Pseudomonas fluorescens: Taguchi–ANN-Based Evaluation of Physico-Chemical Parameters The green production of metal nanoparticles is attracting interest due to its environmentally benign manufacturing methods. Zinc oxide (ZnO) nanoparticles possess significant uses as semiconductors, antimicrobials, and photothermal materials; nevertheless, their production by microbes is still inadequately investigated. This study involved the synthesis of ZnO nanoparticles utilizing Pseudomonas fluorescens, with optimization of the physico-chemical incubation parameters affecting nanoparticle size and polydispersity index (PDI). The biogenic synthesis was validated using ATR-FTIR and X-ray diffraction analysis. Taguchi's L27 orthogonal array and ANOVA at a 95% confidence level were utilized to ascertain the most relevant components. The analysis indicated that pH and aeration were the predominant characteristics, whereas temperature and concentration exhibited modest impacts, and duration had negligible influence. The ideal parameter combination was identified as pH of 7, temperature 40 °C, aeration 220 rotation per minute, duration 3 days, and zinc acetate of 2 mm, resulting in the minimal particle size and lowest PDI. SEM results corroborated the appearance and dimensions anticipated by the model. The findings emphasize that regulating pH and aeration is essential for improving the biogenic synthesis of ZnO nanoparticles, whilst other parameters operate as secondary tuning variables. The ANN model optimized the expected values of particle size at 157.69 nm and PDI at 0.601 for the chosen process conditions, demonstrating substantial concordance with experimental results of 208.54 nm and 0.76, respectively.

Within palm oil, compounds like tocotrienols, tocopherols, carotenoids, and phenolics exhibit notable properties related to antioxidant activity and immune regulation. This study aims to systematically review existing literature to comprehensively assess how palm oil derivatives influence immunotherapy efficacy and safety in cancer treatment. A qualitative research approach was employed using the Systematic Literature Review (SLR) method. Data collection involved a rigorous search of peer-reviewed articles from the ScienceDirect database published between 2021 and 2025. Keywords included "palm oil," "palm oil derivatives," "Elaeis guineensis," and terms related to "immunotherapy," "cancer immunotherapy," and "immune checkpoint." Articles were screened for relevance, open access availability, and publication date, resulting in 29 eligible studies for analysis. Data were systematically extracted and thematically analyzed to identify patterns in mechanistic effects, clinical outcomes, and translational potential. The results demonstrate that palm oil derivatives modulate immune responses by reducing inflammation, enhancing antioxidant defences, and improving immune cell function, thereby potentially increasing immunotherapy effectiveness and reducing adverse effects. Nonetheless, limitations such as low bioavailability and the lack of wide-reaching clinical investigations remain evident. In conclusion, palm oil derivatives show promising adjunctive potential to improve immunotherapy outcomes in cancer treatment. Further research is recommended to optimize formulations, validate clinical efficacy, and establish standardized protocols for clinical application.

Enhancing Reverse Design Ability of Functional Materials Based on Data Quality Management: Taking Biomedical Zinc Alloy as an Example Biodegradable zinc alloys have shown great potential in the biomedical field, but are limited by their poor mechanical properties. Alloying is essential for improving mechanical properties, yet designing multicomponent zinc alloys remains challenging due to complex elemental interactions. Notably, while data-driven active learning approaches offer new strategies for zinc alloy design, data quality issues such as redundancy, outliers, and inconsistencies in multi-source heterogeneous data hinder modeling accuracy and interpretability. In this work, we proposed a data quality management strategy based on recursive screening, targeting three key data problems, namely, redundant data (RD), outlier data (OD), and inconsistent target data (ID). Case studies on hydrogen embrittlement, phase-change refrigeration materials, and matbench_expt_gap datasets showed that, in the aforementioned data-driven research, RD optimized data distribution but risked precision loss in high-performance regions; OD enhanced minority alloy features but risked overfitting; and ID preserved high-performance data, boosting extrapolation but risking underfitting. Six multicomponent zinc alloys were designed and fabricated using these strategies. Experiments showed ID-optimized datasets achieving 482 MPa-near state-of-the-art performance. The highest tensile strength of 482 MPa was obtained in the alloy Zn-1.2Al-0.8Mg-0.45Li-0.3Mn (at%), designed via the ID-optimized dataset. The study revealed that in inverse design, predictive accuracy in high-performance regions outweighs data volume or density, underscoring the value of data quality management for multi-source materials development.
