Researchers Examine Dynamics of Liquid Metal Particles at Nanoscale Two NJIT researchers have demonstrated that using a continuum-based approach, they can explain the dynamics of liquid metal particles on a substrate of a nanoscale. “Numerical simulation of ejected molten metal nanoparticles liquified by laser irradiation: Interplay of geometry and dewetting,” appeared in Physical Review Letters (July 16, 2013). The evolution of fluid drops deposited on solid substrates has been a focus of large research effort for decades, said co-author Shahriar Afkhami, an assistant professor in the NJIT Department of Mathematical Sciences. This effort has become particularly extensive on the nanoscale, due to the relevance of nanostructures in a variety of fields, ranging from DNA sequencing to plasmonics and nanomagnetism. And the research also applies to liquid crystal displays and solar panel designs.”In this work, Afkhami with NJIT Professor Lou Kondic, also in the Department of Mathematical Sciences, studied the liquid metal nanostructures placed on solid substrates. The study is of direct relevance to self- and directed-assembly of metal nanoparticles on surfaces. For example, the size and distribution of metallic particles strongly affects the yield of solar cell devices, Afkhami said. In this work, however, the researchers demonstrate that using a continuum-based approach is appropriate on the nanoscale, where the basic assumptions
