Many works focus on the use of polyesters such as poly(lactic acid) (PLA) to produce nanofibrous scaffolds for cardiac tissue engineering. However, are hydrophobic and difficult functionalize. Here, we show that adding 30% poly(glycerol sebacate) (PGS) elastomer within PLA leads PLA:PGS with improved biological properties, depending processing parameters. Two categories fibers were produced by blend electrospinning, diameters 600 1300 nm. The resulting cured at 90 or 120 °C achieve two...
ABSTRACT Electrospun nanocomposites of poly(ε‐caprolactone) (PCL) incorporated with PCL‐grafted cellulose nanocrystals (PCL ‐g‐ CNC) were produced. PCL chains grafted from (CNC) surface by ring‐opening polymerization. Grafting was confirmed infrared spectroscopy (FTIR) and thermogravimetric analyses (TGA). The resulting CNC then into a matrix at various loadings. Homogeneous nanofibers average diameter decreasing the addition observed scanning electron microscopy (SEM). domains visualized...

Encapsulation TiO2 by improved pretreating pigments with 3-(trimethoxysilyl)propyl methacrylate, making it possible to prepare...
Electrospinning usually results in the formation of scaffolds that are a few hundred microns thickness with pore sizes micron range. However some applications, such as tissue engineering, necessitate fabrication cm-thick nanofibrous large allow for cell infiltration. Here, we demonstrate first time production bioresorbable poly(ε-caprolactone) foams using electrospinning technique. These were obtained through dynamic self-assembly electrospun nanofibers into honeycomb patterns, which...
We present here for the first time a simple method micropatterning nonwoven composite membranes. The approach is based on simultaneous electrospraying of microparticles and electrospinning nanofibers from different polymer solution feeds (polyethylene glycol poly(D,L-lactide)) common support. mechanism self-organization between fibers particles into hierarchical honeycomb-like structures, as well evolution later function thickness composite, investigated. demonstrate that aggregates...
Hierarchical carbon fibers/carbon nanofibers composites, with high effective surface areas and controlled macroscopic shapes, were successfully synthesized through a combination of electrospinning chemical vapour deposition.
The elaboration of biomimetic materials inspired from the specific structure native bone is one main goal tissue engineering approaches. To offer most appropriate environment for reconstruction, we combined electrospinning and electrospraying to elaborate an innovative scaffold composed alternating layers polycaprolactone (PCL) hydroxyapatite (HA). In our approach, electrospun PCL was shaped into a honeycomb-like with inner diameter 160 μm, capable providing cells 3D while ensuring material...
Abstract A macroscopic composite consisting of nitrogen‐doped carbon fibers (N@CFs) was synthesized by electrospinning. The as‐prepared N@CF material further applied as a metal‐free catalyst in the catalytic oxidation H 2 S to sulfur, which is one most important purification processes for raw chemical resources (that is, biogas, natural gas, and petrochemical compounds). catalyst, after carbonization step at T =800 °C, exhibits high stable desulfurization activity more than 100 h testing...
Positive impacts on the PCE by using thiazole instead of thiophene in soluble electron-donor small molecules for OPV.
Boron dipyrromethene (BODIPY) and its derivatives are known to be efficient photon-harvesting chromophores. However, their study as active materials in bulk heterojunction (BHJ) solar cells is still scarce. In this study, the development of new synthetic ways design original BODIPY-based dumbbell-shape molecules, including a first 2,3,5,6-tetravinyl aromatic BODIPY molecule, reported. High fill factors can obtained BHJ when blended with fullerene derivative, leading record power conversion...

The are designed to exhibit semi-permeable properties, enabling insulin diffusion while restricting larger immune molecules, such as immunoglobulin G (IgG). Although electrospinning is a widely used technique fabricating porous controlled drug release, it typically results an average pore size on order few micrometers, which two orders...

Assemblies of nanoparticles are studied in many research fields from physics to medicine. However, as it is often difficult produce mono-dispersed particles, investigating the key parameters enhancing their efficiency blurred by wide size distributions. Indeed, near-field methods analyse a part sample that might not be representative full distribution and macroscopic give average information including all particle sizes. Here, we introduce temperature differential ferromagnetic nuclear...
The gold standard procedure after a severe nerve injury is the autograft, yet this technique has drawbacks. In recent years, progress been made in development of artificial guides to replace but no device able demonstrate superiority. present study introduces an adaptable foundation design for peripheral regeneration.Silk fibroin was electrospun, creating tri-layered material with aligned fiber surfaces and randomly deposited interior. This rolled into micro-channeled conduit, which then...
Bone tissue engineering goes beyond the limitations of conventional methods treating bone loss, such as autograft-induced morbidity and a lack integration for large grafts. Novel biomimicry approaches (using three-dimensional [3D] electrospinning printing techniques) have been designed to offer most appropriate environment cells thus promote regeneration. In present study, we assessed regeneration properties composite 3D honeycomb structure from electrostatic template-assisted deposition...
