“…Through this method, discontinuous core-sheath nanofibers are formed by stretching and collapsing of an emulsion [ 57 , 93 ]. Chemically, two dissimilar polymers are dissolved in a solvent, mixed, and settled to produce an emulsion in which the core and sheath segments form from dispersed drops and the continuous phase, respectively [ 56 , 91 , 94 , 95 ]. To maintain the stability of the emulsion before and during the jet formation, an emulsifier is usually used.…”

Hollow nanofibers are largely gaining interest from the scientific community for diverse applications in the fields of sensing, energy, health, and environment. The main reasons are: their extensive surface area that increases the possibilities of engineering, their larger accessible active area, their porosity, and their sensitivity. In particular, semiconductor ceramic hollow nanofibers show greater space charge modulation depth, higher electronic transport properties, and shorter ion or electron diffusion length (e.g., for an enhanced charging–discharging rate). In this review, we discuss and introduce the latest developments of ceramic hollow nanofiber materials in terms of synthesis approaches. Particularly, electrospinning derivatives will be highlighted. The electrospun ceramic hollow nanofibers will be reviewed with respect to their most widely studied components, i.e., metal oxides. These nanostructures have been mainly suggested for energy and environmental remediation. Despite the various advantages of such one dimensional (1D) nanostructures, their fabrication strategies need to be improved to increase their practical use. The domain of nanofabrication is still advancing, and its predictable shortcomings and bottlenecks must be identified and addressed. Inconsistency of the hollow nanostructure with regard to their composition and dimensions could be one of such challenges. Moreover, their poor scalability hinders their wide applicability for commercialization and industrial use.

In this paper, biodegradable polycaprolactone (PCL) was used as the raw material to prepare micro/nanofibrous polycaprolactone membrane (PCLM) through solution blow spinning (SBS) technology. The effects of spinning conditions (distance, gas pressure, and spinning solution concentration) on PCLM structures were investigated. The obtained membranes were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, water contact angle, and thermogravimetric analysis instrument. The oil adsorbency and reusability of PCLM were measured. The oil adsorption capacity of PCLM for motor oil, peanut oil, and diesel oil was 15.93, 14.81, and 12.86 g·g−1, respectively. After 10 times of reuse, the adsorption capacity for motor oil, peanut oil, and diesel oil could still remain at about 80% of the first cycle. The kinetic and thermodynamic studies showed that the adsorption conformed to the first‐order kinetic model and Freundlich model. Thermodynamic parameters for oil adsorption ΔGθ, ΔHθ, and ΔSθ indicated the oil adsorption of PCLM was a spontaneous and physisorption process.

Biocompatibility, mechanical strength, and osteogenesis properties of three-dimensional scaffolds are critical for bone tissue engineering. In addition, reactive oxygen species accumulate around bone defects and limit the activities of surrounding cells and bone formation. Therefore, the presence of an antioxidant in a bone tissue scaffold is also essential to address this issue. This study aimed to evaluate a composite nanofibrous scaffold similar to the natural extracellular matrix with antioxidant and osteogenic properties. To this end, polylactic acid (PLA)/organophilic montmorillonite (OMMT)/resveratrol (RSV) nanofibers were fabricated using the electrospinning method and characterized. RSV was used as an antioxidant, which promotes osteogenic differentiation, and OMMT was used as a mineral phase to increase the mechanical strength and control the release of RSV. The scaffolds' antioxidant activity was measured using DPPH assay and found 83.75% for PLA/OMMT/RSV nanofibers. The mechanical strength was increased by adding OMMT to the neat PLA. The biocompatibility of the scaffolds was investigated using an MTT assay, and the results did not show any toxic effects on human adipose mesenchymal stem cells (hASCs). Moreover, the Live/Dead assay indicated the appropriate distribution of live cells after 5 days. Cell culture results displayed that hASCs could adhere and spread on the surface of composite nanofibers.Meanwhile, the level of alkaline phosphatase, osteocalcin, and osteopontin was increased for hASCs cultured on the PLA/OMMT/RSV nanofibrous scaffold.Therefore, this study concludes that the RSV-loaded composite nanofibers with antioxidant and osteogenesis properties and appropriate mechanical strength can be introduced for bone tissue regeneration applications.
