“…29 The C-S spectra band, which is between 600 to 700 cm À1 overlaps with the iron oxide vibrational band and it would be hard to distinguish. 30,31 The peak at 1700 cm À1 , which is assigned for stretching of C]O carboxylic group has disappeared from the spectra and instead the peak at 1650 cm À1 has become sharper with high intensity. This suggest that the binding of 3-MPA to Fe 3 O 4 nanoparticles occurs by formation of surface bonds through the COOH group rather than through the SH group.…”

“…Although, it shows less mechanical properties, but mechanical properties can be enhanced by incorporating with other polymers. [71][72][73] A blend of CA/PLA was used by Ahmed et al to enhance the chemical and biological properties. An increase in elastic elongation properties, cell attachment, and nontoxicity were also reported in CA/PLA nanofibers.…”

The practice of using a massive amount of environmental unfriendly and toxic petroleum-based materials in tissue engineering and biomedical fields demands the materials, which are biodegradable, renewable, environmentally friendly, biocompatible, and bioactive. So, renewable polymers have got considerable attention due to their numerous desirable properties. The nanofibers that are prepared from renewable materials and their blends can integrate the properties of both nanofibers and renewable polymers. Development of scaffolds that mimic the construction of tissues at nanoscale is a great challenge for tissue engineering. Electrospinning is the most promising technique for nanofibers formation. Nanofibers provide a platform for cell adhesion, proliferation, and differentiation. Therefore, nanofibers from sustainable materials have been used in tissue engineering and biomedical fields. In this review, methods for nanofibers fabrication, sustainable nanofibers made from natural and synthetic polymers and their applications in tissue engineering and biomedical field, have been emphasized.

“…The major sources of phenol and phenolic compounds are discharges of chemical process industries such as pulp and paper, pharmaceutical, agrochemical, petrochemical, and pesticide production [5]. The accumulation of these pollutants can have adverse effects on human health due to their toxicity, their ability to disrupt the endocrine system and their carcinogenic behavior [6]. Therefore, the improper handling and disposal of these toxic carcinogenic compounds pose a significant risk to the environment and the ecosystem [7,8].…”

Background The removal of phenol from aqueous solution via photocatalytic degradation has been recognized as an environmentally friendly technique for generating clean water. The composite nanofibers containing PAN polymer, CNT, and TiO2 NPs were successfully prepared via electrospinning method. The prepared photocatalyst is characterized by SEM, XRD, and Raman spectroscopy. Different parameters are studied such as catalyst amount, the effect of pH, phenol concentration, photodegradation mechanism, flow rate, and stability of the composite nanofiber to evaluate the highest efficiency of the photocatalyst. Results The composite nanofibers showed the highest photodegradation performance for the removal of phenol using UV light within 7 min. The pH has a major effect on the photodegradation of phenol with its maximum performance being at pH 5. Conclusions Given the stability and flexibility of the composite nanofibers, their use in a dynamic filtration is possible and can be even reused after several cycles.
