Electrospinning is a versatile technique for producing nanocomposite in biomedical applications. In this study, polyurethane (PU) cardiac patch loaded with nickel oxide (NiO) was fabricated using electrospinning technique. The morphology study revealed that the PU/NiO nanocomposites exhibited reduced fiber diameter (758 AE 157.10 nm) and pore diameter (868 AE 73.26 nm) compared to the pristine PU (fiber diameter 890 AE 116.91 nm and pore diameter 1064 AE 74.31 nm). The contact angle study indicated the decreased wettability behavior of the electrospun nanocomposite (106 AE 0.58 ) than the pure PU (100 AE 0.58 ). The incorporation of NiO into PU improved the mechanical strength (15.25 MPa) and surface roughness (448 nm) of the pristine PU (tensile strength 7.12 MPa and surface roughness 313 nm). The developed PU/NiO nanocomposites showed delayed blood clotting time and low hemolytic percentage as revealed in the coagulation studies insinuating the improved anticoagulant nature compared to the pristine PU. Moreover, 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt (MTS) assay demonstrated the nontoxic behavior of fibroblast cells in the developed nanocomposite (135 AE 1%) than the pristine PU (133.33 AE 8.96%). The newly developed nanocomposite patch rendered better physicochemical, improved blood compatibility, and nontoxic to the fibroblast cells. Hence, the electrospun PU/NiO nanocomposite might serve as a plausible scaffold for the cardiac tissue engineering.

“…As a key step in the reduction of NiO by methane, understanding C–H activation on different NiO surfaces (with and without defects) will also enhance our understanding of the process of reduction of NiO. NiO materials synthesized by different methods typically show peaks corresponding to (100), (110), and (111) surfaces in XRD analyses. − Among the different surfaces, NiO(100) is the most stable surface while NiO(110) is a high energy surface . The NiO(111) surface, being polar, will either be hydroxylated or undergo an octopolar reconstruction to minimize the surface energy , and thus is not investigated here.…”

“…Among these methods, the electrospinning has turned out to be a preferable choice because of its simplicity and scalability to yield nanofibers at an industrial level, and easy control over the morphology of the nanofibers [32][33][34][35][36][37][38][39][40]. Nickel oxide nanofiber morphology has gained significant attention due to the strong dependence of properties on the morphology [28,41,42]. The 1D nanofibers are easily modified via various approaches such as doping with heteroatoms, introducing strain in the basal plane, synergizing with conductive materials, coupling with the substrates of more active sites and defects to enhance the electrical conductivity and accelerating the kinetics of charge transfer [43][44][45].…”

Cost-effective, active and stable electrocatalysts are pivotal to hydrogen production via electrocatalytic water splitting. Here we report on the preparation of novel nanofiber (NF) Ni/Gd2O3/NiO heterostructures by an electrospinning technique. The fabricated materials show high electrocatalytic performance for hydrogen evolution reaction (HER) with activities of onset potential at 89 mV, which is almost identical to that of platinum. The chemical and electronic properties of materials are successfully optimized in Ni/Gd2O3/NiO coaxial heterostructures; the NiO NF with Gd 3+ enhances remarkably its electrical conductivity and promotes HER reaction kinetics. It offers the distinct advantages of long-term durability and readiness for the integration into producing hydrogen via HER, affording better performance than benchmark Pt catalysts. The 2 successful fabrication of these metal oxides nanofibers and nanostructures may pave a new path for rational synthesis of efficient HER catalysts.
