Abstract

The in-depth analysis of the characteristics of garlic-loaded nanofibers mats.

Physicochemical properties and performance of graphene oxide/polyacrylonitrile composite fibers as supercapacitor electrode materials

“…The addition of rGOPKS also increased the Young's modulus, because it formed many bonds with the large number of parallel chains. 33,62 The measured strains of the CNF0, CNF1, CNF2, and CNF3 rGOPKS/PAN nanober mats at breakage were 5%, 8%, 9%, and 11%, respectively. All of the strain values exceeded that of typical CNFs ($2.5%).…”

“…It is more difficult to stretch the jet of a highly viscous precursor solution in an electric eld, so the resulting nanobers generally have larger diameters. 33,43,44 The homogeneity of the PAN/rGOPKS bers was evaluated by calculating the coefficient of variation (CF) of the bers in each PAN/rGOPKS sample. The CF is dened as the ratio of the SD to the average ber diameter, and homogeneous bers have CFs below 0.3.…”

A freeze–thaw PVA hydrogel loaded with guava leaf extract: physical and antibacterial properties

“…The zone of inhibition was measured aer 24 h of incubation at 37 C. A 10 mL aliquot was taken for each sample and diluted in a physiological sodium chloride solution several times to obtain a calculated bacterial concentration as described in our previous work. 51 One mL of diluted bacterial suspension was taken and rubbed evenly onto MHA in a Petri dish, then incubated for 24 h at 37 C. Aer incubation, the bacterial colonies from the dilution were counted to determine the amount of bacterial-growth inhibition. The hydrogel antibacterial activity was determined by using 51 Anti bacterial activity ¼ ½ðlog controlÞ À ðlog hydrogelÞ ðmassÞ Â ðlog controlÞ (6)…”

Gelatin hydrogel membrane containing carbonate hydroxyapatite for nerve regeneration scaffold

“…When immersed in water, water molecules entrapped in the interentanglement space and caused interfibrils space. Calcium ions entrapped in a wide surface or entanglement were first dissolved in water, and the ones inside fibril spaces were dissolved during the degradation process (Chang et al, 2003; Chang, Douglas, & Tanaka, 2006; Edikreshna, Suciati, Munir, & Khairurrijal, 2019).…”
