Motivated by recent experimental results on glassy polymer nanoparticles, we develop a minimal theoretical framework for the glass transition in spherical confinement. This is accomplished using our cooperative-string model for supercooled dynamics, that was successful at recovering the bulk phenomenology and describing the thin-film anomalies. In particular, we obtain predictions for the mobile-layer thickness as a function of temperature, and for the effective glass-transition temperature as…

Cooperative strings and glassy dynamics in various confined geometries.
By canceling and restarting any cooperative-chain realization reaching the boundary with a smaller number of steps than the bulk cooperativity, this article accounts for a purely attractive substrate, and explores the impact of the latter in the previous geometries.

Glass transition and fragility of nanosized polymeric fibers and spheres predicted from a surface-controlled model
In a previous article, we proposed a surface-controlled cooperatively rearranging region (SCC) model that mimics the segmental dynamics of supercooled liquids, including polymeric materials. By
A Dynamically Correlated Network Model for the Collective Dynamics in Glass-Forming Molecular Liquids and Polymers
A dynamically correlated network (DCN) model is proposed to understand the growing behavior of dynamically correlated regions during cooling, which leads to the viscous slowdown of supercooled liquids.
Polymer glass transition occurs at the marginal rigidity point with connectivity z* = 4.
Coarse-grained Brownian dynamics simulations show that at sufficient strength of LJ attraction the polymer globule indeed crosses the threshold of z*, and becomes a glass with a finite zero-frequency shear modulus, G∝ (z-z*).
A simulation study on the glass transition behavior and relevant segmental dynamics in free-standing polymer nanocomposite films.
It is demonstrated that NPs will migrate to the film surface area and form an NP-concentrated layer when NP-polymer interactions are weak, while NPs are well dispersed in the bulk region when NP/nanoparticle composite interactions are strong.
Glass forming phase diagram and local structure of Kob-Andersen binary Lennard-Jones nanoparticles.
It is found that surface enrichment of the large atoms alters the nanoparticle core composition, leading to an overall shift of the glass forming region to lower small atom mole fractions, relative to the bulk system.
Collective Motion in the Interfacial and Interior Regions of Supported Polymer Films and Its Relation to Relaxation.
The extent of collective motion, as quantified by string-like molecular exchange motion, is similar in magnitude in the polymer-air interfacial layer as the film interior, and distinct from the bulk material.
Capillary deformation of ultrathin glassy polymer films by air nanobubbles
The authors show that air nanobubbles nucleated at solid-liquid interfaces can deform ultrathin glassy polystyrene films, leading to the formation of nanocraters.


String model for the dynamics of glass-forming liquids.
A living polymerization theory quantitatively describes the interrelation between the average string length L, configurational entropy Sconf, and the order parameter for string assembly Φ without free parameters and is used to predict the relaxation time τ in a lower temperature T range than accessible by current simulations.
Cooperative strings and glassy interfaces
A minimal analytical model is introduced, which invokes only the ideas of molecular crowding and string-like cooperative rearrangement, before addressing the key effects of interfaces, and suggests that dynamics in glass-forming materials might be understood from elementary arguments.
Structures and Dynamics of Glass-Forming Colloidal Liquids under Spherical Confinement.
A colloidal system is designed, where particles are confined inside spherical cavities with an amorphous layer of particles pinned at the boundary, and a simple relation for the change of the configurational entropy of confined colloidal liquids is proposed, which quantitatively explains the experimental findings and illustrates a divergent static length scale during the colloidal glass transition.

A mobile layer is found responsible for the surface transport, as previously conjectured, and it is shown that it has a velocity profile decaying exponentially into the bulk.
Heterogeneous dynamics at the glass transition in van der Waals liquids, in the bulk and in thin films
Abstract:It has been shown over the last few years that the dynamics close to the glass transition is strongly heterogeneous, both by measuring the diffusion coefficient of tagged particles or by NMR
Reduction of the glass transition temperature in polymer films: a molecular-dynamics study.
Results of molecular-dynamics simulations for a nonentangled polymer melt confined between two completely smooth and repulsive walls, interacting with inner particles via the potential U(wall)=(sigma/z)(9), are in qualitative agreement with that of the glass transition temperature observed in some experiments on supported polymer films.
The shapes of cooperatively rearranging regions in glass-forming liquids
The cooperative rearrangement of groups of many molecules has long been thought to underlie the dramatic slowing of liquid dynamics on cooling towards the glassy state. For instance, there exists
Effect of Free Surfaces on the Glass Transition Temperature of Thin Polymer Films.
The concept of cooperative rearrangement was introduced in an attempt to unify these two views of the glass transition by demonstrating that such cooperativity, coupled with a thermodynamic glass transition, resulted naturally insystem dynamics such as those described by the WLFequation for temperatures near freezing.

The role of nanoconfinement on the glass transition temperature (T(g)) of polymers has been extensively studied in the thin film geometry and the general trend of T(g) depression in nanospheres was found to be similar to the results onthin film geometry.

Abstract:A simple and predictive model is put forward explaining the experimentally observed substantial shift of the glass transition temperature, Tg, of sufficiently thin polymer films. It focuses
