A general and robust strategy for in-situ templated synthesis of patterned inorganic nanoparticle assemblies
TL;DR: In this paper, the block copolymer template is used to limit the vertical growth of inorganic nanoparticles to achieve thickness control in the nanometer scale. But this method is not applicable to all inorganic nano-articles.

Machine Learning Predictions of Block Copolymer Self-Assembly.
Kun-Hua Tu,Hejin Huang,Sangho Lee,Wonmoo Lee,Ze-Hao Sun,Alfredo Alexander-Katz,Caroline A. Ross +6 more
TL;DR: Here, machine learning tools are applied to analyze the solvent annealing process and predict the effect of process parameters on morphology and defectivity, yielding accurate prediction of the final morphology in agreement with experimental data.

Synthesis of CO2-Based Block Copolymers via Chain Transfer Polymerization Using Macroinitiators: Activity, Blocking Efficiency, and Nanostructure
Yao-Yao Zhang,Guan-Wen Yang,Yanyan Wang,Xin-Yu Lu,Guang-Peng Wu,Ze-Sheng Zhang,Kai Wang,Kai Wang,Ruo-Yu Zhang,Paul F. Nealey,Paul F. Nealey,Donald J. Darensbourg,Zhi-Kang Xu +12 more
TL;DR: In this article, the authors systematically studied the reaction activity and blocking efficiency by using various macro-CTAs (including PPG, PEG, and PS) in the presence of two classical catalyst systems ((BDI)ZnOAc and SalenCoTFA/PPN-TFA) by analyzing the gel permeation chromatograms via mathematical deconvolution.

Structure and Dynamics of Asymmetric Poly(styrene-b-1,4-isoprene) Diblock Copolymer under 1D and 2D Nanoconfinement
Wycliffe Kiprop Kipnusu,Mahdy M. Elmahdy,Mahdy M. Elmahdy,Emmanuel Urandu Mapesa,Jianqi Zhang,Winfried Böhlmann,Detlef-M. Smilgies,Christine M. Papadakis,Friedrich Kremer +8 more
TL;DR: The dynamic glass transition, related to the segmental modes of the styrene and isoprene blocks, is independent of the dimensionality and the finite sizes of confinement, but the normal mode is influenced by both factors with 2D geometrical constraints exerting greater impact.

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.
