A block copolymer self-consistent field theory (SCFT) model is used for direct analysis of experimental X-ray scattering data obtained from thin films of polystyrene-b-poly(methyl methacrylate) (PS-b-PMMA) made from directed self-assembly. In a departure from traditional approaches, which reconstruct the real space structure using simple geometric shapes, we build on recent work that has relied on physics-based models to determine shape profiles and extract thermodynamic processing information… 
Bayesian model calibration for block copolymer self-assembly: Likelihood-free inference and expected information gain computation via measure transport
This work considers the Bayesian calibration of models describing the phenomenon of block copolymer (BCP) self-assembly using image data produced by microscopy or X-ray scattering techniques and introduces several domain-specific energy- and Fourier-based summary statistics and quantifies their informativeness using EIG.
Characterisation of the PS-PMMA Interfaces in Microphase Separated Block Copolymer Thin Films by Analytical (S)TEM
Using advanced analytical transmission electron microscopy ((S)TEM), this work provides real space information on polymer domain morphology and interfaces between polystyrene (PS) and polymethylmethacrylate (PMMA) in cylinder- and lamellae-forming BCPs at highest resolution.
Defect Annihilation Pathways in Directed Assembly of Lamellar Block Copolymer Thin Films.
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.
Machine Learning Predictions of Block Copolymer Self‐Assembly
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.
Dynamic coarse-graining of polymer systems using mobility functions
A dynamic coarse-graining scheme for mapping heterogeneous polymer fluids onto extremely CG models in a dynamically consistent manner by introducing internal friction parameters that slow down the CG monomer dynamics on local scales, without affecting the static equilibrium structure of the system.
Multicore Assemblies from Three-Component Linear Homo-Copolymer Systems: A Coarse-Grained Modeling Study
Using dissipative particle dynamics (DPD) simulations, it is demonstrated how simple, three-component linear polymer systems consisting of free solvophilic and solvophobic homopolymers, and di-block copolymers, can self-assemble in solution to form well-defined multicore assemblies.
A globally convergent modified Newton method for the direct minimization of the Ohta-Kawasaki energy with application to the directed self-assembly of diblock copolymers
A fast and robust scheme for the direct minimization of the Ohta-Kawasaki energy that characterizes the microphase separation of diblock copolymer melts is proposed and is shown to be mass-conservative, energy-descending, asymptotically quadratically convergent, and three orders of magnitude more efficient than the commonly-used gradient flow approach.

Fabrication of sub-10 nm topographical guiding patterns, block copolymer directed self-assembly, thorough morphology analysis and free energy modelling.

Small-angle X-ray scattering from block copolymers as an ideal model system for a pseudo two-phase solid texture
The microdomain structure of polystyrene-polyisoprene A-B type block copolymers was analysed by small-angle X-ray scattering (SAXS) as an ideal model system for a pseudo two-phase solid structure.
