Work by Mingqiu Hu*, Xindi Li, William T. Heller, Wim Bras, Javid Rzayev, and Thomas P. Russell* was recently published in Macromolecules. In this work, researchers used grazing-incidence small-angle neutron scattering (GISANS) to probe the depth-dependent orientation of self-assembled morphologies of block copolymers.
