Cylinder Orientation and Shear Alignment in Thin Films of Polystyrene–Poly(n-hexyl methacrylate) Diblock Copolymers
TL;DR: In this article, a series of PS-PHMA diblocks of varying composition, all forming PS cylinders, are synthesized and their morphology studied as a function of film thickness in both nonsheared and shear-aligned films.

TL;DR: This work examines the pathways for annihilation of defects in symmetric diblock copolymers in the context of directed assembly using patterned substrates and shows that multiple consecutive free energy barriers lead to effective kinetic barriers that are an order of magnitude larger than those originally reported in the literature for tightly bound dislocation pairs.

Ordered mesoporous molecular sieves synthesized by a liquid-crystal template mechanism
TL;DR: In this paper, the synthesis of mesoporous inorganic solids from calcination of aluminosilicate gels in the presence of surfactants is described, in which the silicate material forms inorganic walls between ordered surfactant micelles.

Block Copolymer Thermodynamics: Theory and Experiment
TL;DR: Block copolymers are macromolecules composed of sequences, or blocks, of chemically distinct repeat units that make possible the sequential addition of monomers to various carbanion-ter minated ("living") linear polymer chains.

Block Copolymers—Designer Soft Materials
TL;DR: The Knitting Pattern as mentioned in this paper is a block copolymer that was discovered by Reimund Stadler and his coworkers and reflects a delicate free-energy minimization that is common to all blockcopolymer materials.
