Directed self-assembly of diblock copolymers on chemically patterned substrates: phase behavior and defect kinetics
Research division · MME
Molecular & Materials Engineering
Soft-matter self-assembly, heterogeneous catalysis, functional materials and green chemistry — understanding how molecules organize and react, then designing materials that do something specific.
Overview
Molecular & Materials Engineering is the division where chemistry, physics and engineering meet at the nanoscale. MME researchers design and characterize new substances — polymers, colloidal assemblies, catalysts, piezoelectrics and organic semiconductors — with properties specified in advance rather than discovered by screening. The aspiration is predictive synthesis: know what you want the material to do, understand the relevant physics, build it.
The division's three groups address complementary scales of organization. The Soft Matter & Self-Assembly Group focuses on systems in which entropy and non-covalent forces determine structure: block copolymers that template nanoscale features, colloidal particles that form photonic crystals, and biological membranes that remodel on demand. The Catalysis & Green Chemistry Lab works at the molecular scale of bond-making and bond-breaking, developing heterogeneous and photo-driven catalysts that minimize energy input and avoid hazardous solvents. The Functional Materials Group works from molecule to device, designing organic electronics, ferroelectric ceramics and shape-memory polymers for specific end functions.
MME draws heavily on the Spectroscopy & Analytical Core for NMR, mass spectrometry and X-ray characterization, and on the Advanced Microscopy Centre for nanoscale imaging. The Veyra Biofoundry supports high-throughput synthesis campaigns in the Catalysis & Green Chemistry Lab.
Research themes
- Entropic and enthalpic self-assembly — controlling phase behavior, defect density and long-range order in soft-matter systems through chemistry and boundary conditions.
- Earth-abundant metal catalysis — iron, manganese and copper catalysts for reactions that currently require platinum-group metals.
- Photo-driven and electrochemical synthesis — using photons or electrons as the primary energy source for bond-forming reactions, reducing reliance on thermal routes.
- Responsive and adaptive materials — polymers and ceramics that change stiffness, shape or electronic state in response to a defined stimulus.
- Materials data and prediction — machine-learning models for property prediction, active-learning campaigns for catalyst discovery, and the Veyra Atlas predictor developed with CDS.
Research groups
Three groups addressing assembly, reaction and function at distinct but connected scales.
Soft Matter & Self-Assembly Group
Colloidal systems, block-copolymer mesophases and bio-inspired structural materials — understanding how nanoscale forces produce macroscopic order.
Catalysis & Green Chemistry Lab
Heterogeneous and photo-driven catalysis for low-energy synthesis, with a focus on earth-abundant metal catalysts and solvent-free reaction design.
Functional Materials Group
Responsive polymers, piezoelectric ceramics and organic electronic materials designed for specific device functions rather than intrinsic properties alone.
