“…Gelatin, as a kind of natural material, is hydrolyzed from collagen in animals, which has many advantages, such as good accessibility, a wide source of raw materials and low cost. Its amino acid composition is similar to collagen and has good biocompatibility, biodegradability and low immunogenicity [7,8,9]. Especially in the past decades, with the development of electrospinning technology, gelatin fibers can be prepared simply and quickly.…”

Traditional wound dressings require frequent replacement, are prone to bacterial growth and cause a lot of environmental pollution. Therefore, biodegradable and antibacterial dressings are eagerly desired. In this paper, gelatin/ZnO fibers were first prepared by side-by-side electrospinning for potential wound dressing materials. The morphology, composition, cytotoxicity and antibacterial activity were characterized by using Fourier transform infrared spectroscopy (FTIR), X-ray diffractometry (XRD), particle size analyzer (DLS), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), thermogravimetry (TGA) and Incucyte™ Zoom system. The results show that ZnO particles are uniformly dispersed on the surface of gelatin fibers and have no cytotoxicity. In addition, the gelatin/ZnO fibers exhibit excellent antibacterial activity against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) with a significant reduction of bacteria to more than 90%. Therefore, such a biodegradable, nontoxic and antibacterial fiber has excellent application prospects in wound dressing.

“…As expected, the signals of Si and O can be found in CdS@void@SiO 2 YSNs XPS spectrum. Two distinguished peaks at 103.8 and 154 eV are attributed to Si2 s and Si2 p of SiO 2 , respectively . The peak at 533.3 eV is clearly visible for CdS@void@SiO 2 YSNs; and it could be attributed to O1s in SiOSi groups, suggesting the presence of SiO 2 .…”

photocatalysts including Bi-based photocatalysts, [1] Co-based photocatalysts, [2] carbon nitride (C 3 N 4 ), [3] cadmium selenide (CdSe), and cadmium sulfide (CdS) [4] have been developed for utilizing sunlight efficiently. Among them, one of the most representative photocatalysts is CdS, which possesses high photosensitivity and excellent photocatalytic performance owing to its relatively narrow bandgap (E g = 2.2 eV) and appropriate band structure posi-

“…Due to the stretching of –OH and –NH, the gelatin molecule has a wide adsorption band at 3280 cm −1 [ 39 ]. Furthermore, the characteristic peaks at 1629, 1531 and 1237 cm −1 correspond to amide I, amide II and amide III, respectively, in which the amide I band is mainly attributed to the tensile vibration of –C=O, and the amide II and Ⅲ bands were caused by the bending vibration of -NH and the stretching vibration of –C–N, respectively [ 40 ]. In addition, due to the reaction between the aldehyde group of glutaraldehyde and the amino lysine residue of gelatin, the stretching vibration peak of the imide group (–CH=N) appears at 1450 cm −1 [ 41 ].…”

In this paper, environmentally friendly gelatin/β-cyclodextrin (β-CD) composite fiber adsorbents prepared by electrospinning were used for the removal of dyes from wastewater. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and a universal materials tester were employed to characterize the internal structures, surface morphologies and mechanical strength of the composite fiber adsorbents. Additionally, the fiber was evaluated as an adsorbent for the removal of methylene blue (MB) from aqueous solution. The effects of the raw material ratio, pH, temperature, concentration and adsorption time were studied. The results show that the gelatin/β-CD composite fiber adsorbents possess excellent mechanical strength and high adsorption efficiency for MB. The adsorption equilibrium and adsorption kinetics are well-described by the Langmuir isotherm model and the pseudo-second-order kinetic model, respectively. The theoretical maximum adsorption capacity is 47.4 mg·g−1. Additionally, after nine successive desorption-adsorption cycles, the removal rate is still over 70%. Moreover, the gelatin/β-CD composite fiber adsorbents exhibit excellent adsorption capability for basic fuchsin, gentian violet, brilliant blue R and malachite green dyes. Therefore, owing to the characteristics of degradability, low cost and high-efficiency, the gelatin/β-CD composite fiber can be used as an efficient adsorbent for the removal of dyes from wastewater.
