Fabrication of biodegradable fibrous systems employing electrospinning technology for effluent treatment

“…85 Table 4 illustrates the different parameters and their effects on ber morphology. Taylor's mathematical expression can be used to calculate the critical voltage of a particular system at which the electrospinning process commences (eqn (5)), as follows: 39 V c 2 ¼ 4H 2 h 2 ðlnð2h=RÞ À 1:5Þð1:3pRgÞð0:09Þ The spinning voltage plays a vital role in forming high-performance, efficient, and moderatediameter bers among the other processing parameters, where a signicant increase in the voltage to an optimum or critical value results in ber uniformity, leading to ultrathin nanobers with the formation of Tylor cones at a critical voltage. The critical voltage of a system varies from biopolymer to biopolymer.…”

“…Furthermore, the addition of surfactants lowers the surface tension, decreases the ber diameter and enhances the ber morphology. 39 4.1.6. Effects of environmental parameters.…”

“…Electrospinning is receiving tremendous attention due to its ability to prepare complex geometries and brils. 36,39 The fabricated electrospun nanobers can eliminate organic and inorganic contaminants from wastewater owing to their adjustable wettability, high length-to-diameter ratio, and surface morphology. 38,40 The eradication of contaminants from aqueous system utilising electrospun nanobrous membranes involves ltration and adsorption mechanisms.…”

“…85 Table 4 illustrates the different parameters and their effects on fiber morphology. Taylor's mathematical expression can be used to calculate the critical voltage of a particular system at which the electrospinning process commences (eqn (5)), as follows: 39 where V c = critical voltage for electrospinning; H (cm) = spinning distance; h (cm) = liquid column length; c (Dyn cm −1 ) = surface tension of the spinning solution and R (cm) = spinneret inner radius. A factor of 0.09 is combined with the equation to estimate the critical voltage.…”

Shock Wave-Assisted Exfoliation of 2D-Material-Based Polymer Nanocomposites: A Breakthrough in Nanotechnology

“…Customarily, exfoliation refers to the technique involving the expansion of layered materials employing extraneous factors, i.e., physical or chemical forces to diminish the interlayered noncovalent interactions, eventually segregating them into monolayered sheets . The majority of the layered materials , including graphene, − molybdenum disulfide (MoS 2 ), and hexagonal boron nitride (hBN) , are bound by feeble secondary forces along the (001) plane causing facile detachment of the layers via chemical or mechanical methodologies by surmounting the secondary forces. Exfoliation of bulk materials into distinct layered sheets of 10 –9 m thickness imparts a diverse spectrum of material characteristics, such as substantial augmentation in the surface area to volume ratio consequently yielding enhanced catalytic activity and reactivity of these materials that cannot be achieved in its bulk state.…”
