Compared with that prepared by single autoclave foaming, PBAT microcellular foams prepared by the combination of autoclave foaming and vacuum foaming possessed a higher VER up to 7.60, which had an increase of 324.58%. GNPs were used for the achievement of the filling modification of PBAT, which increased the cell density and compression properties of PBAT foams.

As a result, scientists are searching for complementary, alternative, or even combination medicines with fewer adverse effects and high efficacy. One type of statin that is effective in treating some forms of cardiovascular disease is Atorvastatin, which is also recognized as a suitable therapeutic option for inhibiting the growth of angiogenesis and coronary vessel pathogenesis. In the current research, we synthesized and characterized magnetic Fe3O4–chitosan nanoparticles loaded with Atorvastatin (ch/Fe/ATV), and we evaluated their anti-tumor efficiency in-vivo as well as their anti-proliferative, apoptotic, and the cell cycle arrest effects on the C6 glioma cell line in-vitro. In C6 cells, it was discovered that ch/Fe/ATV was useful in inducing ROS, apoptosis-induced cell death, and suppression of proliferation. During the in-vivo stage of the study, it was shown that ch/Fe/ATV could effectively reduce tumor development and improve the survival rate of animal models of GBM. qRT-PCR findings in this study demonstrate that ch/Fe/ATV may down-regulate anti-apoptotic factors including Bcl-2, VEGF, and BDNF, which are critical factors in tumor growth, and up-regulate apoptotic factors such as BAX, Caspase 3, and p53. Additionally, we discovered that applying a magnet to the tumor site helped increase the amount of ATV doses delivered to the tumor using ch/Fe/ATV nanoparticles.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142214972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the high cost and the need to improve the mechanical properties have limited their widespread use. Blending with other bio-based polymers, such as poly(lactic acid) (PLA), has been proposed in previous studies. This study investigates the effects of temperature, azodicarbonamide (AZ, foaming agent), boron nitride (BN, filler), and multilayer film/foam coextrusion on the properties of a blend containing an amorphous PHA and PLA. The effect of twin-screw micro-compounder temperature (185 °C & 205 °C) and BN concentrations of 1, 2, 3, 5, and 10 wt% (185 °C) on the properties of the PHA/PLA blend were investigated using differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and tensile testing. Design of experiments (DoE) was used to find the optimal concentrations of AZ and BN (205 °C) using JMP® software. The response surface analysis predicted an optimal design based on the target response levels (modulus, tensile strength, strain at break, and toughness). This formulation was prepared and characterized using DSC, TGA, tensile, and melt flow index (MFI) measurements. Finally, this formulation was processed via film/foam coextrusion and examined using scanning electron microscopy (SEM) and density measurements. This study demonstrated that AZ and BN can be used to manipulate the mechanical properties and crystallinity of PHA/PLA blends, while reducing the overall material cost via density reduction (20–21% for the optimal formulation). Furthermore, reducing the concentration of AZ using the I-optimal design in this study could alleviate the toxicity concerns for food packaging.","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142214731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We synthesized bio-based cationic water-dispersed crosslinked polyurethanes from high oleic soybean oil (HOSO) polyol, isophorone diisocyanate, and methyldiethanol amine, with varying ionic group contents after neutralization with acetic acid. Our primary objective was to analyze how crosslinking affects the dispersion process and film properties in multifunctional systems. The synthesis-structure-property relationship is elucidated through comprehensive analyses of the products at different stages of the synthesis. The dispersion of the WPU particles in water must occur prior to gelation during the final preparation, leading to incomplete conversion and the formation of imperfect networks. Insight into the synthesis process and polymer structure was gained by simulating polymer network parameters. Morphological analyses using synchrotron-based X-ray scattering and atomic force microscopy revealed a hierarchical structure within the WPU films.

A pivotal finding of the investigation is that the (PoAP)-G/AgNPs composite with a 1:2 ratio exhibits the most diminutive particle size (83.16 nm), and the utmost negative zeta potential (− 35.4 mV).

In this study, Fe(III) was doped into sodium alginate-based gel beads to analyze the principle of its action in enhancing the adsorption performance of the gel beads by revealing the role of Fe(III) cross-linking. Meanwhile, the adsorption mechanism of phosphate removal was explored. The addition of Fe(III) displaces part of the cross-linking between Ca(II) and sodium alginate, forming a solid monodentate covalent coordination structure with the carboxyl group of sodium alginate. 2% iron doping concentration forms better lattice support and pore structure so that its specific surface area increases and has abundant adsorption sites. Compared with the gel beads without iron, the gel beads with 2% iron realize a 4-fold increase in phosphate adsorption. With a high adsorption efficiency, the adsorption reaction can reach equilibrium in 2 h. The adsorption is mainly monolayer chemisorption, and the maximum adsorption capacity can reach 84.08 mgPO43−-P/g. Compared with calcium alginate, iron salts are preferentially and rapidly adsorbed to phosphate, followed by the formation of modified phosphates and iron hydrogen phosphate salts and the formation of the corresponding iron salts.

However, their susceptibility to flammability presents a significant challenge. Enhancing the flame retardancy of these aerogels has been a prominent focus of research, with the widespread use of inorganic fillers and layered materials for this purpose. In the current study, our objective is to fabricate cellulose nanofiber aerogels characterized by low density, exceptional flame retardancy, high mechanical properties, and thermal insulation. This is achieved through the cross-linking of melamine and formaldehyde under aqueous conditions using an eco-friendly freeze-drying process, followed by post-curing. The resulting aerogels demonstrate flexibility, effective sound absorption within the mid-frequency range, and outstanding flame retardancy (Limiting Oxygen Index ∼33%) with a non-flammable behaviour. The thermal conductivity of the fabricated melamine formaldehyde-modified cellulose nanofiber (MF-CNF) aerogels was 0.064 ± 0.014 W/m.K. MF-CNF aerogels exhibited a Time to Ignition (TTI) of 489 s, whereas pristine CNF aerogels only have 3 s. This improvement was attributed to the concurrent reductions in both the Peak Heat Release Rate (PHRR) and Fire Growth Rate (FIGRA) of MF-CNF aerogels. The straightforward melamine formaldehyde modification of CNF aerogels enhances their mechanical strength as well as fire resistance. These sustainable multifunctional aerogels hold great potential for a variety of real-life applications in the realm of buildings and its structures for ensuring fire safety and sound insulation.<h3 data-test=\"abstract-sub-heading\">Graphical Abstract</h3>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":null,"pages":null},"PeriodicalIF":5.3,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141934328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
