In this work, a novel drug delivery system consisting of poly(ε-caprolactone) (PCL) electrospun fibers containing an ad-hoc-synthesized star polymer made up poly(amido-amine) (PAMAM) core and PCL branches (PAMAM-PCL) was developed. The latter which synthesized via the ring opening polymerization ε-caprolactone, starting from hydroxyl-terminated PAMAM dendrimer characterized by means 1H NMR, IR DSC, found to be compatible with both matrix hydrophilic chemotherapeutic drug, doxorubicin (DOXO),...
In this work, a novel biobased system, characterized by specific features suitable for the removal of water pollutants, was developed. Indeed, system consists electrospun stereocomplex polylactide (sc-PLA)-based fibers, prepared from solutions containing equimolar amounts high-molecular-weight poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA), functionalized with an amino polyhedral oligomeric silsesquioxanes (POSS-NH2), which added directly into electrospinning solution. The sc-PLA/POSS-NH2...
The development of three-dimensional (3D) biomaterials that mimic natural tissues is required for efficiently restoring physiological functions injured and organs. In the field soft hydrogels, self-assembled peptides (SAPs) stand out as distinctive biomimetic scaffolds, offering tunable properties. They have garnered significant attention in nanomedicine due to their innate ability self-assemble, resulting creation fibrous nanostructures closely microenvironment extracellular matrix (ECM)....
Piezoelectric materials can provide
Poly (butylene terephthalate) (PBT) nanofiber mats were prepared by electrospinning, being directly deposited in the form of a random fibers web. The effect changing processing parameters such as solution concentration and electrospinning voltage on morphology electrospun PBT nanofibers was investigated with scanning electron microscopy (SEM). diameter increased rising decreased increasing voltage, thermal mechanical properties characterized DSC tensile testing, respectively.
Abstract Polymer piezoelectric nanogenerators have attracted attention for mechanical energy harvesting, powering wearable electronics and movement sensing applications. Polyvinylidene fluoride (PVDF) is a flexible efficient electroactive polymer, however, it polymorph which only two phases (of five) are piezoelectric. Herein produced breathable textile‐compatible mats via electrospinning, the polymorphism of PVDF nanofibers during deposition controlled, rather than post‐fabrication, meaning...
Poly(buthylene terephthalate)(PBT)/single wall carbon nanotubes (SWCNTs) composite nanofibers were prepared by electrospinning. The effect of on the morphology, crystallization, and mechanical properties electrospun investigated SEM, DSC, tensile testing, respectively. SEM observations indicated that presence SWCNTs resulted in finer for lower loading; however, a broader distribution, especially higher diameter ranges was found with amounts nanotubes. accelerated crystallization acted as...
Spinal cord regeneration using stem cell transplantation is a promising strategy for regenerative therapy. Stem cells transplanted onto scaffolds that can mimic natural extracellular matrix (ECM) have the potential to significantly improve outcomes. In this study, we strived develop carrier by culturing neural (NSCs) electrospun 2D and 3D constructs made up of specific crosslinked functionalized self-assembling peptides (SAPs) featuring enhanced biomimetic biomechanical properties....
Abstract Self-assembling peptides (SAPs) have gained significant attention in biomedicine because of their unique properties and ability to undergo molecular self-assembly driven by non-covalent interactions. By manipulating composition structure, SAPs can form well-ordered nanostructures with enhanced selectivity, stability biocompatibility. offer advantages such as high chemical biological diversity the potential for functionalization. However, studies concerning its potentially toxic...
In this study, the effect of zirconium oxychloride (ZrOCl 2 ) with different concentrations citric and formic acids on flame-retardant properties wool is assessed by thermal analysis, mass loss, limiting oxygen index (LOI) vertical flame. Scanning electron micrographs have been prepared to observe compare surface morphology raw treated samples. It has observed that ZrOCl exhausted onto flame retardancy natural markedly improved. The agents show an increase in temperature decomposition...
Abstract The thermal degradation of wool treated with the flame retardant synergistic system, zirconium acetate, acid citric, and hydrochloric acid, was studied by analysis, mass loss, limiting oxygen index (LOI), vertical test.

Zirconium oxychloride, a well-known flame retardant, is introduced as novel mordant for wool dyeing. This has been indicated by mordanting of yarns with zirconium oxychloride in different conditions and then dyeing madder famous natural dye.
