Understanding how respiratory droplets become droplet nuclei and their dispersion is essential for understanding the mechanisms and control of disease transmission via droplet‐borne and airborne routes. A theoretical model was developed to estimate the size of droplet nuclei and their dispersion as a function of the ambient humidity and droplet composition. The model‐predicted dried droplet nuclei...
This research used Ceramic Injection Molding (CIM) formulation technique of ceramics/polymers, selecting two Al2O3 powders (α- and θ-Al2O3), kneading of several polymers with the ceramic powder, and extruding to produce feedstocks and filaments, which was used for 3D additive manufacturing. Four tasks were completed. First, PP as the major binder, replaced with some EVA, to improve the flexibility...
Carbon nanotubes (CNTs) with its exceptional electrical properties has become one of the most potential materials to be used as conductive filler in polymer composites. However, to obtain maximum transfer of electrical properties of CNTs to the composites, well dispersed and electrically connected CNTs in polymer matrix has to be achieved. Vertically aligned carbon nanotubes with network structures...
