In article number 2213888, Jinyou Xu, Ernesto Joselevic, and co-workers propose a universal strategy for the self-oriented growth of organic nanowires on faceted polymer films.Consequently, nanowires are integrated into photodetectors directly on a flexible film. This in-situ integration strategy helps nanowire-based flexible …

WebFeb 2, 2011 · Crystal growth occurs when solute molecules in solution diffuse to the surface of the crystal, become adsorbed onto the surface and are then incorporated into the crystal lattice. For some systems, incorporation of solute into the crystal is easy and growth is limited by diffusion to the crystal surface through bulk solution or boundary … WebCooling the solution rapidly encourages fast crystal growth, since there is less room for the dissolved salt in the cooler, denser solution. As the solution cools, the magnesium sulfate atoms run into each other and join …
