The results of these experiments were used to perform adsorption isotherm, kinetics, and thermodynamics calculations. The pseudo-second-order kinetic equation and the Langmuir isothermal equation were found to fit the experimental data best. The Au(III) ion saturation capacity of the PBTR particle monolayer was calculated to be 1771.73 mg/g at 328 K using the Langmuir isotherm.

To overcome these drawbacks, electrostatic and covalent strategies have been used to combine oligomers with nanoparticles (NPs) to enhance stability and cellular internalization. Polymeric NPs, prepared from oil-<em>in</em>-water (O/W) PLGA nano-emulsions (NEs) using low-energy emulsification methods, have shown potential in many biomedical applications owing to their ability to transport drugs across cellular membranes. Carbodiimide-mediated amine coupling reaction and thiol-based Michael-type addition were used to attach FdU oligomers formed by five FdU residues (FdU₅) to PLGA NPs. Colloidally stable dispersions of FdU₅-decorated PLGA NPs were obtained and characterized in terms of size, surface charge, and morphology in physiological medium. Additionally, synthetic strategies were envisaged to functionalize the surface of FdU₅-decorated polymeric NPs with folic acid (FA). Cell culture experiments showed that FdU₅-decorated PLGA NPs were able to internalize efficiently inducing cytotoxic effect and inhibiting cell proliferation in tumor cells. These outcomes suggest the feasibility of grafting oligomeric FdU produgs in a covalent fashion into nanoscale platforms as a potential approach for cancer therapy.</p></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1381514824001342/pdfft?md5=3125bf853b483d7e42779c9b9ea17fee&pid=1-s2.0-S1381514824001342-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141298016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the degradation rate decreased with increasing crystallization temperature and that the enzyme adsorption decreased and the degradation rate increased with increasing second monomer unit ratios. The enzymatic degradation mechanism was clarified based on the kinetic parameters and especially focused on the reaction resistance; specifically, the degradation proceeded in series from the surface of the stacked crystalline and amorphous phases. Furthermore, the degradation of the crystalline phase was rate-limiting, and the reaction resistance of the crystalline phase increased proportionally with the lamellar thickness.

PEG is a type of oligomer used as a shape memory effect modifier for CE. Due to the low toughness of CE-based polymers, they are often modified with epoxies to increase their toughness. However, the high molecular chain length of PEGs can also act as a plasticiser increasing the toughness of the CE/PEG-based SMPs instead of epoxies. This study explores the synergistic use of PEG with CE to optimise SMPs with comparable mechanical and shape memory properties, along with tailorable glass transition temperatures. During the synthesis, PEG 600, 1000, 2000 &amp; 4000 were individually combined with CE monomers in varying stoichiometric ratios to produce a set of SMP specimens. Thermo-mechanical properties, and shape memory properties were experimentally obtained and graded as a function of different molecular weights of PEGs and their stoichiometric ratios. CE SMPs modified with PEG600 and 1000 exhibited stable storage moduli and therefore selected for further investigation. A single-parameter empirical model was developed to correlate T_g with stoichiometric ratios, enabling the prediction of T_g values for different CE: PEG600/1000 ratios or vice versa. The tensile and flexural properties at elevated temperatures were also studied. Notably, the use of lower molecular weight PEGs mitigated the storage modulus drops, while higher molecular weight PEGs significantly improved the toughness. Moreover, synthesised SMPs in the T_g range of 125–130 °C using PEG600 and PEG1000 showed improved stability of storage modulus. The SMP with PEG600 showed better thermo-mechanical properties, storage modulus stability at higher temperatures, and shape memory behaviour compared to the SMP with PEG1000. This research contributes to developing robust and adaptable SMPs for space environments, bridging the gap between mechanical performance and shape memory capabilities.</p></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":null,"pages":null},"PeriodicalIF":5.1,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S138151482400124X/pdfft?md5=a8eea05199171729c4cc924f1e62e89a&pid=1-s2.0-S138151482400124X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141242456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For improving the biodegradability of antibiotic production wastewater, hybrid process of resin adsorption and Fenton oxidation was proposed. The adsorption experiments showed that NDA-150 exhibited removal rates of up to 99.1% and 94.8% for two key pollutants 8-hydroxyquinoline (8HQ) and <em>o</em>-aminophenol (OAP), respectively. The constant removal rates demonstrated stable performance and capacity of NDA-150 for practical industrial operation.
