Electrospinning of fibrous tissue engineering scaffolds has been traditionally conducted using positive voltages. In the current study, positive voltage (PV) electrospinning and negative voltage (NV) electrospinning were investigated for forming fibrous membranes of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV). In both PV-electrospinning and NV-electrospinning, the fiber diameter generally i...

Micro- and nanosized plastics as persistent anthropogenic pollutants have attracted more attention in recent years. A source of nanoparticles is, for example, water-borne dispersion paint, which consists a variety different materials with potential adverse effects on living systems. Therefore, rising challenge becomes apparent to investigate remediation strategies environmental media. We addres...

Dyes, antibiotics, heavy metal ions, and bacteria are important sources of water pollution. How to solve these issues has become a problem in the fields science technology. People have developed variety technologies treat pollutants water. Photocatalytic technology came into being. As simple environmentally friendly treatment technology, it been widely studied by scientific community. Tradition...

The following manuscript presents the first attempt to fabricate and characterise electrospun polycaprolactone/poly(succinimide) composite meshes. While each material has its own advantages, a mesh could provide further options in wide diverse application spectrum of fibrous membranes. Polycaprolactone is well-known polymer with excellent mechanical properties resistance against most chemicals....

Poly-L-lactic acid (PLLA) nanofibrous membranes are widely utilized for tissue regeneration. Low intensity pulsed ultrasound (LIPUS) has been considered as a feasible modality for bone union. The aim of the present study was to investigate the potential synergistic effect of LIPUS and PLLA electrospun nanofibrous membranes on large cortical bone defects in rabbits in vivo. The bilateral rabbit ...

Poly(vinylidene fluoride-trifluoethylene), P(VDF-TrFE), electrospun membranes were obtained from a mixture of dimethylformamide (DMF) and methylethylketone (MEK) solvents. The inclusion of MEK to the solvent system promotes a faster solvent evaporation allowing complete polymer crystallization during the jet travelling between the tip and the grounded collector. The main electrospinning process...

Surface modification of polymeric scaffolds for biomedical applications is a versatile and widely used method to improve interactions between cells. Specifically, chemical immobilization proteins provides significant advantages such as stable biocompatible properties, however, it generally requires expensive instruments or complex steps. In this study, the facile presented that changes poly (l-...

The electrospinning technique, which was invented about 100 years ago, has attracted more attention in recent years due to its possible biomedical applications. Electrospun fibers with high surface area to volume ratio and structures mimicking extracellular matrix (ECM) have shown great potential in tissue engineering and drug delivery. In order to develop electrospun fibers for these applicati...

Acoustic sensors show a wide application in diverse fields. However, it is still challenge to develop highly sensitive transducing materials for the detection of low-to-middle decibel sounds. Herein, first time remarkable property an acoustic sensor based on electrospun polyacrylonitrile (PAN) nanofibers recognition human voices reported. The nanofiber device shows sensitivity as high 23 401 mV...
