Summary: Nature's self-assembly technology allows for the creation of a wide range of nanoparticles with different structures and morphologies. However, current artificial self-assembly platforms are limited in their ability to define the interaction between seeds and growth materials, resulting in the fabrication of single type of nanoparticles with limited structures. We have developed a versatile super-assembly platform that can fabricate diverse nanoparticles with tunable architectures and morphologies, offering a powerful toolset for various applications including drug delivery and nanomaterial assembly.

Summary: It is shown that when water-soluble Ag-9-cored nanoclusters (Ag-9-NC) are confined in crowded colloids, they self-assemble into ultra-long, flexible and photoluminescent ribbons. The ribbons contain rectangularly organized columns of Ag-9-NCs and can form bundled and branched structures. The high viscosity/elasticity of the colloids weakens the sedimentation of the ribbons, resulting in the formation of an interesting class of inorganic-organic composite materials.

Summary: This study investigates self-assembly patterns of low-functionality telechelic star polymers in dilute solutions using synthesis, physical experiments, and computer simulations. The focus is on the effect of arm composition and length on the static and dynamic properties of these polymers. Experimental results are in good agreement with coarse-grained simulations, providing insights into the thermoresponsive behavior mechanism of this class of materials.

Summary: The study investigates effective interactions in dilute polydisperse ring polymer solutions, deducing the contributions of sterics, topology, and threading for differently sized rings. The research also quantifies the contribution of topological constraints for rings of different asymmetries in length, as well as compares changes in effective potentials when mutual ring threading is restricted. Threading depth distributions at different center-of-mass ring separations are also characterized.

Summary: A hierarchy of multiscale modeling approaches were applied to investigate the structure of ring polymer solutions under planar confinement. Comparisons with explicit molecular dynamics simulations showed consistency among approaches, with ring polymers exhibiting a higher propensity to structure in confinement compared to linear polymers.

Summary: In this study, we investigate the effects of crowding on the conformations and assembly of confined, highly charged, and thick polyelectrolyte brushes. Particle tracking experiments and theoretical simulations reveal that aggregation and re-entrant ordering occur due to the combined effect of osmotic pressure and short-range attraction. The attraction is caused by blunt-end interactions between stretched DNA fragments of neighboring brushes.

Summary: In this study, we investigated the active topological glass under spherical confinement to determine the critical exponents of the arrested conformations beyond the previous simulated chain lengths. We discovered a previously unresolved tank-treading dynamic mode of active segments along the ring contour and discussed possible connections of the conformational and dynamic features of the system to chromosomes enclosed in the nucleus of a living cell.

The influence of topology and specific sequence of reactive groups on the potential was investigated. The validity of the effective potentials in solution was tested and found to be in good agreement with simulations of the real system.

Summary: Concentrated solutions of semiflexible polyelectrolyte ring polymers can form nanoscopic cylindrical stacks, and the morphology and dynamics of these clusters can be controlled by the presence of counterions. Addition of trivalent ions stabilizes the formation of clusters, while monovalent ions affect the density of the clusters.

Summary: This computational study investigates the effects of molecular topology (linear and circular) and counterion valency on the effective pairwise interactions between unlinked DNA molecules. Umbrella sampling simulations are performed to calculate the effective pair interaction potentials. The results show contrasting effects of divalent counterions on the repulsion between linear DNA molecules and DNA minicircles. Linear DNA fragments can adopt orientations that minimize repulsions, while DNA minicircles exhibit a greater bending effect due to their free ends.

Summary: We derive and parameterize the effective interaction potentials between different types of ring polymers and linear chains, and investigate the behavior of mixtures with varying solvent quality. Our results show that worsening of the solvent quality leads to a stronger phase separation tendency in the mixtures. We also propose a criterion to determine whether a specific linear-ring mixture will undergo phase separation.

Summary: In this study, molecular dynamics simulations were used to investigate the supercooled dynamics of the Gaussian Core Model at low and intermediate densities. The results show that the dynamics at low densities can be described by the caging mechanism, leading to intermittent dynamics. At high densities, the particles exhibit a more continuous motion where the concept of cage becomes irrelevant. It is suggested that these different supercooled dynamics are precursors of two different glass states, which is supported by the transition from intermittent to non-intermittent dynamics observed in the single-particle trajectories of the supercooled Gaussian Core Model.

Summary: The major objective of research in nanofluidics is to achieve better selectivity in manipulating the fluxes of nano-objects, especially biopolymers. Numerical simulations were used in this study to investigate the behavior of polymers under flows in slit pores at the nanoscale. The results showed that different types of flow, such as Poiseuille flows and electroosmotic flows, can lead to quantitatively and qualitatively different behaviors of the polymer chains. Furthermore, a counterintuitive phenomenon was observed in the presence of electroosmotic flow, where the shear-induced forces led to a stronger repulsion of the polymers from the solid surfaces, resulting in increased flowing velocity and the potential for polymer separation.

Summary: In this study, the replica method was used to investigate the dynamical glass transition of the Gaussian core model. It was found that a smooth transition occurs between continuous and discretized glass states at different temperatures, and the glass melts as the density is further increased. Comparing to impenetrable particles, the glass physics of ultrasoft particles is more diverse due to their ability to create and break out-of-equilibrium clusters of overlapping particles.
