3D hybrid Ni-Multiwall carbon nanotubes/carbon nanofibers for detecting sarin nerve agent at room temperature

Morphology and Properties of Electrospun PCL and Its Composites for Medical Applications: A Mini Review

“…Due to its versatility, electrospinning is an extremely essential technique for the treatment of different fillers with disparate textural nature and properties, such as ceramic nanofibers, carbon nanofibers, whiskers and extracted natural polymer materials [27,28]. The fabrication of fillers by the electrospinning method, results in the altered nano-structural orientation of the resultant fibrous materials, which possess significantly reduced dimensional size in order to produce outstanding mechanical responses as well as the necessary and essential biomedical activities.…”

“…These structural orientations are observed by examining the electric response of the individual thread of the fiber. However, when the threads of the fiber reorganize, upon the grounded collector, the mats of different structural orientations are formed and the architectural blueprint leads to the generation of beaded, random, aligned, patterned yarns and 3D structural nanofibers [28,29]. The electrospinning technique is the most preferred over others; on the account of its: (1) simplicity when utilized to a variety of materials and a very cost-effective method for nanofiber modification, (2) capacity to allow the introduction of bioactive compounds into the nanofibers and (3) utilization of the electrostatic force instead of heat during the processing of nanofibers, since heat can be detrimental to the structure of the highly thermal sensitive materials.…”

“…In recent years, a plethora of electrospun nanoparticles have been prepared by the electrospinning method in order to alter the dimensional size, for the formation of ultrafine nanofibers and also to attain a uniform porosity, which provides effective use in biomedical applications e.g., tissue engineering, wound dressing. For example, Lui and co-workers [28] prepared the 3D Ni-multiwall carbon nanotubes/carbon fibers by the electrospinning method in order to afford a smooth surface hybrid material with diameters ranging between 20-30 nm, leading to a very efficient sensing capacity for detecting sarin nerve agent at 25 • C. Notwithstanding the impressive task that the electrospinning process possesses in the preparation of various nanomaterials with well-controlled nanofibrous size and refined porosity across the resultant membranes, factors such as the set-up for the electrospinning technique, conditions of an ambient environment and properties of the pristine nanoparticles, altogether, influence the diameters and the morphologies of the envisaged electrospun nanofibers.…”

Carbon nanofiber-based three-dimensional nanomaterials for energy and environmental applications

“…For instance, Alali and co-workers reported the fabrication of 3D hybrid Ni-multiwall carbon nanotube (Ni-MWCNTs)/ CNFs nanomaterials via combined electrospinning and CVD synthesis. 56 As shown in Fig. 5, previously mixed PAN/PVP precursors were utilized to form PNF mats by electrospinning and then the as-spun PNF mats were carbonized to form a CNF matrix.…”

HFIP‐Functionalized Co3O4 Micro‐Nano‐Octahedra/rGO as a Double‐Layer Sensing Material for Chemical Warfare Agents

“…Unfortunately, these agents were modified and designed to be a silent killer and lethal weapon to kill a large number of people after breathing them for few seconds . There are many kinds of chemical warfare agents such as sarin, soman, tabun, and phosphonothioic acid (VX) . On exposure to CWA, these toxins directly attack the nervous system and create covalent bonds with the serine residue at the active site of the enzymes, which causes inhibition of the enzyme acetylcholinesterase.…”
