Defects and defect engineering in Soft Matter
TL;DR: A survey on investigations on defects and/or defect engineering in nine classes of soft matter composed of liquid crystals, colloids, linear polymers with moderate degree of branching, hyperbranched polymers and dendrimers, conjugated polymers, polymeric networks, self-assembled amphiphiles and proteins, block copolymers and supramolecular polymers is presented.

Highly Asymmetric Phase Behaviors of Polyhedral Oligomeric Silsesquioxane-Based Multiheaded Giant Surfactants
Mingjun Huang,Kan Yue,Jiahao Huang,Chang Liu,Zhe Zhou,Jing Wang,Kan Wu,Wenpeng Shan,An-Chang Shi,Stephen Z. D. Cheng +9 more
TL;DR: The results showed that the lamellar morphology, which usually existed at relatively symmetric compositions in common diblock copolymers, became the thermodynamically stable phase in the 3DPOSS-PSn and 4DPOSSn samples even at an asymmetric composition.

Hydrogen Bond Assisted Assembly of Well-Ordered Polyhedral Oligomeric Silsesquioxane–Block Copolymer Composites
TL;DR: In this article, a well-ordered block copolymer nanocomposites with d-spacings as small as 15 nm and additive loadings greater than 70 mass % were formed upon blending functionalized polyhedral oligomeric silsesquioxanes (POSS) additives into disordered blockcopolymers containing poly(ethylene oxide) (PEO) as one of the blocks.

10 nm Scale Cylinder–Cubic Phase Transition Induced by Caramelization in Sugar-Based Block Copolymers
Issei Otsuka,Takuya Isono,Cyrille Rochas,Sami Halila,Sébastien Fort,Toshifumi Satoh,Toyoji Kakuchi,Redouane Borsali +7 more
TL;DR: In this paper, a phase transition from hexagonally close-packed cylinder to body-centered cubic at 10 nm scale is discussed in a natural/synthetic hybrid block copolymer system based on an oligosaccharide and poly(e-caprolactone) via thermal annealing.

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.
