“…The resultant RDF that defined the probability of finding the CNT at varying distances r from the carbon nanofiber surface at the initial distance (t = 0) and final equilibrium distance (t = 500 ps) is shown in Figure 1i. 35 Compared to the initial position, the higher g(r) values at t = 500 ps within 6 Å indicate the rapid approach of CNTs toward the fiber surface. Such simulations support the formation mechanism in which the spontaneous assembly of CNTs onto CNFs established the interconnected and robust nanonetworks.…”

“…In order to offer a comprehensive understanding of the interaction mechanism, we further executed an in-depth analysis of the radial distribution function (RDF) for the nanomaterial systems. The resultant RDF that defined the probability of finding the CNT at varying distances r from the carbon nanofiber surface at the initial distance ( t = 0) and final equilibrium distance ( t = 500 ps) is shown in Figure i . Compared to the initial position, the higher g ( r ) values at t = 500 ps within 6 Å indicate the rapid approach of CNTs toward the fiber surface.…”

The tremendous menace of the COVID-19 pandemic has underscored the urgency for antipathogen masks to stop the transmission of airborne infectious diseases. Most prevailing antipathogen masks manifest a slower sterilization rate that lags behind the pathogen momentum traversing the masks, thereby engendering an elevated susceptibility to infection. Here we tailor nanofibrous meta-aerogel electric traps, 3D-assembled from self-knotted carbon nanotube networks in an all rigid nanofibrous skeleton. This superior configuration revolves around the creation of numerous "dielectrophoretic−aerodynamic grippers", which are capable of directional manipulation of microbes toward the region of the lethal intensive electric field. Based on this, we present a disinfection unit comprising a pair of aerogel electrodes that demonstrate a rapid killing rate (>99.99% biocidal efficacy within 0.016 s) and longterm durability (12 h of continuous operation). Additionally, a microbutton lithium cell is employed as a power supply to fabricate an antipathogen face mask with this disinfection unit, which exhibits superior pathogen inactivation efficacy compared to commercial masks. This scalable biocidal protective equipment holds great potential for use in emergency medical services.
