Single-chain elasticity is of fundamental importance in polymer physics, as it underlies many of the unique properties of polymer systems. Recently, there has been interest in characterizing the elastic properties of catenanes, molecular architectures composed of linked molecular rings. To date most studies have focused on the force-extension behavior of polycatenane and catenane dimers. In...

Light-induced mechanical actuation in materials offers a powerful route to remote, reversible control of shape and function, supporting advances in soft robotics, adaptive optics, and smart surfaces. The development of artificial molecular machines, including light-driven rotary motors, was recognized by the 2016 Nobel Prize in Chemistry for “the design and synthesis of molecular machines”,...

The non-equilibrium dynamics of inhomogeneous polymer systems undergoing processes that change the number of polymers is an essential component of many biological systems, such as solvent exchange with an external reservoir or the binding of small molecules to a polymer backbone. Our previous theories were formulated in the canonical ensemble, fixing the number of polymers and limiting our...

Inverted block-copolymer phases reverse the usual curvature rule by forming discrete domains composed of the majority components. These novel structures offer promising applications but often remain unstable in simple block-copolymer melts. The emergence and relative stability of inverted phases in binary AB/CD diblock-copolymer blends are studied using self-consistent field theory. The model...

Thin film samples can be highly influenced by interfacial properties and often have strongly depth-dependent properties. This effect can be even stronger in materials or materials produced by additive manufacturing, where the material is deposited sequentially in layers. While studying film-averaged and near-surface measurements can be straightforward, depth-dependent measurements remain a...

Stable glasses formed through physical vapour deposition exhibit high surface mobility, allowing for their characteristic efficient packing. In thin films of stable polymer glasses, properties of the surface, such as the roughness and elastic modulus, differ as a function of stability and film thickness. In this work, we investigate the surface properties of varying stable polystyrene glasses...

We use nanoindentation to measure the Young's modulus of thin films of polystyrene stable glass fabricated with the help of physical vapor deposition (PVD). Glasses formed this way exhibit fictive temperatures as low as Tg – 20 K and kinetic stability down to deposition temperatures of ~ 0.84 Tg. The Young's modulus of stable glass films is significantly higher than that of ordinary...
