Nanomaterials offer unique properties not seen in their macroscopic kin. They can be used in printed electronics, as catalysts, and so much more. However, their diminutive size complicates materials processing techniques. They can easily aggregate become no longer useful. A solution to this is to use a polymeric surfactant such...
Materials that exist as well-defined individual entities at the nanoscale typically have properties that sets them apart from their bulk form. Consequently, there has been much time and effort invested in developing new well-defined nanoscale entities, but few attempts to assemble them into bulk materials. On the other hand, there...
Ultrafine particles are often used as lubricant additives because they can enter tribological contacts to reduce friction and protect surfaces from wear. They tend to be more stable than molecular additives under high thermal and mechanical stresses during rubbing. However, in lubricant oil, ultrafine particles tend to aggregate together to...
