    Article Title: Electrosprayed Magnetic Poly(butyl methacrylate- co -(2-dimethylaminoethyl) methacrylate- co -methyl methacrylate)/Iron Oxide Microparticles for Efficient Curcumin Delivery
    Article Snippet: Differential scanning calorimetry (DSC) was conducted with a Shimadzu DSC60 Plus calorimeter at a heating rate of 10 °C/min from 200 to 300 °C, under an argon purge (50 mL/min).

    Article Title: Regulation of Corn Starch Gel’s Rheological Properties and Entanglement Behavior by Spring-Dextrin with Different Degrees of Polymerization
    Article Snippet: In this study, Spring-Dextrins (SD) with varying degrees of polymerization (DP) were prepared via the synergistic action of pullulanase and α-amylase.. The effects of SD addition on the entanglement concentration (Ce), rheological properties, and hydrogen-bonding ratios of starch solutions were systematically investigated, with molecular dynamics (MD) simulations employed to elucidate the underlying mechanisms at the microscopic level.. The results demonstrated that SDL and SDM, characterized by higher DP, significantly promoted the entanglement of starch macromolecular chains (Ce decreasing to 0.77 % and 1.22 %) respectively.

    Article Title: Evaluating the efficiency of touch-spun scaffolds in producing dense cell cultures for tissue engineering applications.
    Article Snippet: Diffraction patterns were collected using a D2 PHASER diffractometer (Bruker) with Cu Kα (λ = 1.54059 Å) radiation over a 2θ range of 5–65°, with a step size of 0.02°.

    Article Title: Graphene oxide-loaded electrospun polylactic acid/gelatin nanofiber membranes with enhanced antibacterial properties for wound dressings.
    Article Snippet: Wound dressings should meet essential requirements such as antibacterial activity, efficient exudate absorption, and biocompatibility.. However, pristine polylactic acid (PLA) nanofiber membranes cannot meet these requirements due to their low toughness, strong hydrophobicity, and weak antibacterial properties.. In this study, biodegradable nanofiber membranes based on PLA/gelatin (Gel)/graphene oxide (GO) were prepared via electrospinning for use as wound dressings.

    Article Title: Circularity in Polyamide Textiles: Enhancing Recycled Polymer Molar Mass with Carbodiimide Linear Coupling
    Article Snippet: .. XRD analyses were carried out using a D2 Phaser diffractometer (Bruker, model D2-204967) equipped with a normal focus Cu Kα radiation source, operating at a maximum output of 2 kW and featuring a vertical goniometer with a 185 mM scanning range. ..

    Article Title: Synthesis of Chitosan-Stabilized Silver Nanoparticles under In Situ and Ex-Situ Conditions and Their Biological Applications
    Article Snippet: Silver nanoparticles were obtained in the presence of 2-propanol under both in situ and ex situ conditions.. It was established that the hydrodynamic radius and polydispersity of the particles increase with rising pH (6.0–11.0) due to the accelerated reduction of Ag+ ions.. Variation of the chitosan molecular-weight parameters and the chitosan/Ag+ molar ratio (5–30) enabled controlled formation of stabilized nanoparticles ranging from 20 to 140 nm.
