Zn-Fe flower-like nanoparticles growth by gas condensation
Lamsaf, H.; Lenzi, V.; Marques, L.; Rebouta, L.; Carvalho, S.; Ballesteros, Lina F.; Cerqueira, Miguel Ângelo Parente Ribeiro; Teixeira, J. A.Bimetallic nanoparticles have gained attention in the last decade due to their unusual characteristics compared to monometallic counterparts. However, production of such particles with controlled morphologies and composition need to be explored and the mechanisms understood. In this work, we demonstrate a fast and simple process to obtain flower-like Zn-Fe (Zinc-Iron) nanoparticles (NPs) using a hybrid system b...
Aliphatic isocyanurates and polyisocyanurate networks
Driest, P. J.; Lenzi, V.; Marques, L.; Ramos, M. M. D.; Dijkstra, D. J.; Richter, F. U.; Stamatialis, D.; Grijpma, D. W.The production, processing, and application of aliphatic isocyanate (NCO)-based thermosets such as polyurethane coatings and adhesives are generally limited by the surprisingly high viscosity of tri-functionality and higher-functionality isocyanurates. These compounds are essential crosslinking additives for network formation. However, the mechanism by which these high viscosities are caused is not yet understo...
