A wonderful structure produced with modern technology of 3D printing arrived today by post. The 3D print was produced in the group of Dr. C. Heath Turner, Associate Professor at the Department of Chemical and Biological Engineering, the University of Alabama, USA. The structure represents an approximatelly one hundred thousand times magnified nano-structure of block copolymers under electric field and was first obtained by computer simulation in the group of Andrei Zvelindovsky in collaboration with scientists from Japan (Ly D.Q., Honda T., Kawakatsu T., Zvelindovsky A.V. “Kinetic pathway of gyroid-to-cylinder transition in diblock copolymer melt under electric field” Macromolecules 40 (2007) 2928-2935).
