Empirical research has demonstrated that plants absorb only a minor fraction of the applied herbicide, with the remainder undergoing various dissipation processes, such as photodecomposition, microbial degradation, adsorption, volatilization, leaching, and chemical degradation. Despite the well-documented adverse environmental and health impacts, herbicides continue to be utilized to enhance crop productivity and ensure food security. This underscores the urgent need for the development of herbicide formulations in view of reduce the dumping of herbicide residues in to the agricultural environment. Nanotechnology presents a viable solution by facilitating the precise and efficient delivery of herbicides, thereby mitigating the risks associated with improper usage and environmental contamination. Nanoherbicides have demonstrated superior weed control efficacy and improved crop yields while significantly reducing the rate of herbicide application. Moreover, two primary release profiles are offered by the controlled release characteristics of nanoherbicides: sustained (gradual) release and stimuli-responsive (triggered) release. Sustained release utilizes a polymeric membrane to regulate herbicide diffusion, ensuring prolonged and controlled effects. On the other hand, herbicide release is triggered by external triggers such as light, pH, temperature, or ultrasound in stimuli-responsive systems. This ensures sustained weed management throughout the crop growing season. This review focuses on the release kinetics of nanoherbicides, drawing on evidence from water release studies and their behavior in soil matrices. The analysis highlights the potential of nanoherbicides to revolutionize weed management practices by combining efficiency with environmental sustainability.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 8","pages":"2699 - 2715"},"PeriodicalIF":3.1,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we report the synthesis of amine-functionalized polystyrene/poly(acrylic acid-acrylamide-ethylene glycol dimethacrylate) [PS/P(AA-AAm-EGDMA)-NH₂] composites for aqueous CO₂ adsorption. Polystyrene (PS) particles were initially produced via a dispersion polymerization. Subsequently, acrylic acid (AA) and acrylamide (AAm) were copolymerized in the presence of the PS particles as seeds. Ethylene glycol dimethacrylate (EGDMA) was used as a cross-linker to form PS/P(AA-AAm-EGDMA) composites. In the final step, amide groups (-CONH₂) were partially transformed into primary amine (-NH₂) groups via a <i>Hoffmann</i> degradation reaction. The functionalization was validated using conventional diazonium salt and Schiff base formation assays, as well as Fourier transform infrared (FTIR) and proton nuclear magnetic resonance (¹H-NMR) spectroscopy. Moreover, scanning electron microscopy (SEM) images showed uniform, spherical particles with a smooth texture. Additionally, dynamic light scattering (DLS) and zeta potential measurements showed pH-dependent changes in particle size and surface charge. The amphiprotic nature of the PS/P(AA-AAm-EGDMA)-NH₂ composites was demonstrated through adsorption capacities of 1.132 mmol g⁻¹ for anionic sodium dodecyl sulfate (SDS) at pH 4 and 0.74 mmol g⁻¹ for cationic hexadecyltrimethylammonium bromide (HTABr) at pH 10. Notably, the polymer composite exhibited a CO₂ adsorption capacity of 7.143 mmol g⁻¹, significantly higher than the unmodified PS/P(AA-AAm-EGDMA) (1.668 mmol g⁻¹), retaining 61.1% of its initial adsorption efficiency following three regeneration cycles.

Processing conditions including shear rate, processing temperature and shearing time can affect the final microstructure of TPVs. Morphological study of resultant TPVs was carried out using a scanning electron microscope. The object of this study is to investigate the effect of temperature (210–230 °C, 170–190 °C, 150–170 °C and 140–160 °C) and speed of production process on the properties of TPV based on poly(styrene-b-(ethylene-co-butylene)-b styrene) triblock copolymer/polypropylene (PP)/linear low-density polyethylene prepared via reactive extrusion. Melt flow index (MFI) of the prepared samples was sharply decreased (from 24.4 to 2.63 g/10 min at 190 °C, 10 kg) with decreasing temperature (from 210–230 °C to 170–190 °C). However, hardness of the prepared TPVs was increased to a limiting value (80 shore A) with decreasing the process temperature. Compression set sharply decreased (from 70 to 49% at 120 °C, 70 h) and it has reached to a limiting value (46%). The process temperature, however, is not significantly affected on the tensile strength and tensile strength at 20% extension of the TPV. The elongation has the lowest value in 170–190 °C. Result of elongation at break after aging was improved (from 12.2 to 3.3%) with decreasing process temperature (from 140–160 °C to 210–230 °C). The lowest value of tensile strength (4.1%) was obtained in 170–190 °C after aging. Due to the increase in speeds of the twin screw extruder (180–250 rpm, in 140–160 °C) surface quality was suitable and smooth. Also TPV samples were prepared by either one-step or two-step reactors using the extruder system and the results were compared. In the one-step method, a pronounced higher value in elongation at break (897%) and MFI (6.8 g/10 min at 190 °C, 10 kg) were observed. It was found that the results of heat aging were improved using the two-step process. The two-step process led to higher tensile stress at 20% extension (from 2.7 to 3.3 MPa), too. In addition, a comprehensive experimental study was carried out to achieve the optimal process conditions for the production of TPVs using the two-step process. In one method (method A), the curing agent was added in the first step of the production. Other components such as PP, antioxidant, which may interfere with the peroxide curing were mixed in the second step of the process. In another method (method B), thermoplastic elastomer was produced in the first step, and then curing agent was added in the second step of the productions. The TPV then was prepared in the second step of the process. Generally, the results show that the properties of the prepared TPV with the method B are superior to the method A.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 8","pages":"2977 - 2997"},"PeriodicalIF":3.1,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, machine learning (ML) has emerged as a useful method for predictions based on experimental data. ML can predict a numerical value through numerous supervised models, which are trained and assessed to determine the optimal option. Upon attaining the desired accuracy, the selected model can be applied for prospective predictions and interpreted to extract useful insights. The aim of our study was to apply a hybrid ML approach to predict the release profiles of an antibiotic (silver sulfadiazine) from temperature-responsive hydrogels based on in vitro data. The study explored hydrogel formulations of varying PF-127 and cellulose percentages, temperatures, and drug concentrations. Under this hybrid approach, ML models were investigated alongside different kinetics and mechanisms models. Six ML models—random forest, Gaussian regressor, linear regression, MLP regressor, support vector machine, and kernel ridge—were adopted to predict experimental drug-release data. Model performances were evaluated through the correlation coefficient (R²) and mean absolute percentage error (MAPE). We found that the random forest model exhibited a superior performance, achieving an R² of 0.99 and MAPE 0.002, indicating a robust fit to the data. The release half-life (t_50%) increased as temperature rose from 18 to 32 °C, then decreased at 40 °C, while increasing the drug percentage and polymer concentration prolonged t_50%. Zero-order and Higuchi kinetic models best fit the data, with non-Fickian diffusion and Super Case II mechanisms dominating. These findings demonstrate the potential of ML to streamline pharmaceutical development, reducing the need for extensive laboratory trials.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 8","pages":"2911 - 2932"},"PeriodicalIF":3.1,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
