“…3 A). The HPMC nanofibers are hypoallergenic and have excellent biocompatibility and skin adhesion 24 , 25 , while PVA is an excellent matrix for storing and releasing drug molecules 26 , 27 . The two HPMC layers are 5.2 μm thick and consist of 110 ± 20 nm nanofibers to provide structural support for the 30.5 mm thick electrospun PVA (200 ± 40) nm.…”

This work describes a versatile electrospinning equipment with rapid, independent, and precise x–y–z movements for large-area depositions of electrospun fibers, direct writing or assembly of fibers into sub-millimeter and micron-sized patterns, and printing of 3D micro- and nanostructures. Its versatility is demonstrated thought the preparation of multilayered functional nanofibers for wound healing, nanofiber mesh for particle filtration, high-aspect ratio printed lines, and freestanding aligned nanofibers.

“…This compound is a broad-spectrum antibiotic isolated from the bacterium species, namely Streptomyces venezuelae (Roushani et al 2020 ). Based on binding to the bacterial ribosomal subunit, chloramphenicol inhibits the formation of protein, causing bacterial death (Bayrakci et al 2021 ). Thereby, chloramphenicol is preferable to the treatment of diseases regarding gram-positive, gram-negative, and anaerobic bacteria in humans and animals (Busch et al 2020 ).…”

Chloramphenicol is a broad-spectrum bacterial antibiotic used against conjunctivitis, meningitis, plague, cholera, and typhoid fever. As a consequence, chloramphenicol ends up polluting the aquatic environment, wastewater treatment plants, and hospital wastewaters, thus disrupting ecosystems and inducing microbial resistance. Here, we review the occurrence, toxicity, and removal of chloramphenicol with emphasis on adsorption techniques. We present the adsorption performance of adsorbents such as biochar, activated carbon, porous carbon, metal–organic framework, composites, zeolites, minerals, molecularly imprinted polymers, and multi-walled carbon nanotubes. The effect of dose, pH, temperature, initial concentration, and contact time is discussed. Adsorption is controlled by π–π interactions, donor–acceptor interactions, hydrogen bonding, and electrostatic interactions. We also discuss isotherms, kinetics, thermodynamic data, selection of eluents, desorption efficiency, and regeneration of adsorbents. Porous carbon-based adsorbents exhibit excellent adsorption capacities of 500–1240 mg g −1 . Most adsorbents can be reused over at least four cycles.

Nanofibers have received extensive attention in the fields of biomedicine, energy catalysis, environmental sciences, and filtration owing to their high specific surface area and controllable porosity. Electrospinning and centrifugal spinning are the two most effective methods for fabricating nanofibers. However, the low preparation efficiency of electrospinning limits the use of that technology in the large-scale production of nanofibers. The morphology of nanofibers prepared by centrifugal spinning is slightly inferior to electrospinning. Centrifugal electrospinning has great industrial application potential. It is a new method for fabricating nanofibers formed by combining centrifugal and electrostatic forces. It can efficiently fabricate nanofibers with good alignment. In particular, the use of polymer melt as the spinning precursor for centrifugal electrospinning can effectively address the problem of solvent residue in the fiber. In this review, the working principle and device used for centrifugal electrospinning is introduced, the influence of different components of the spinning device on the spinning process is discussed, and the effects of spinning parameters on fiber properties are explained. Then, some applications of nanofibers fabricated are described by centrifugal electrospinning in various areas, including energy, biomedicine, and filtration. Finally, the challenges of centrifugal electrospinning are summarized, and a perspective on future research is provided.
