shell section in an amorphous state separately due to favorable secondary interactions such as hydrogen bonding. Compared with the electrospun HPMC–AAP nanocomposites from single-fluid electrospinning of the core fluid, the core–shell nanohybrids were able to promote the water absorbance and HMPC ...
Then, the fibers were withdrawn from the solution, rinsed with ultrapure water, and dried overnight in a desiccator. The AOL solution was freeze-dried to obtain powdered AOL before the immobilization process. Then, the covalent immobilization of AOL onto Glu/AP/MNC/PES fibers was performed. ...
The PEO addition to the polysaccharide/zein blend was chosen to give more elasticity to the fibers. PEO is commonly employed as a representative model in electrospinning procedures due to its water solubility, ease of electrospinning, and non-toxic nature [28]. 2. Materials and Methods 2.1. Mat...
The nanofibre membranes are an ideal choice for wound dressings because of their functional versatility. They are able to mimic the fibrous architecture of the natural extracellular matrix (ECM) to support cell attachment and proliferation, are permeable to water vapour and oxygen, and can provide ...

The electrospun fibers are known to be potentially used in different technological fields, such as wound healing, oil removal, gas shielding, drug delivery, protective clothing, sensors and tissue engineering [1,9,10,11]. Among all, electrospun systems appeared to be promising as scaffolds for ...
Water in the atmosphere can also affect the formation of the Taylor cone structure. Depending on the relative humidity, the fibers tend to absorb the water from the air during the elongation step. Water condensation releases latent heat. In response, the fibers expel the solvent earlier, ...
assumption that water droplets on the surface are in full contact with the scaffold surface. As well as liquid media during drug release, constant stirring before and during sampling makes the presence of air in the space between the fibers an unlikely occurrence....
Multiple failure points at lower forces along the 90° axis indicated separation of individual or bundles of fibers. For the hydrogel sample (Figure 1E), increased tensile strength was noted along the 90° axis, with a break force of 2539 mN. Figure 1. (A) Image of the BNRD comprising ...
