New insights into re-entrant melting of microgel particles by polymer-induced aggregation experiments
10.1039/C7SM01922J 2018-04-11 While microgels are in general described as soft particles polystyrene (PS) microgels can be synthesized in a way that cross-link density has only a minor influence on their physical properties. Even though the particles swell in a good solvent the imparted s... |

Modeling the free-radical polymerization of hexanediol diacrylate (HDDA): a molecular dynamics and graph theory approach
10.1039/C8SM00451J 2018-04-11 In the printing, coating and ink industries, photocurable systems are becoming increasingly popular and multi-functional acrylates are one of the most commonly used monomers due to their high reactivity (fast curing). In this paper, we use molecular dynamics ... |

Synchronization in pairs of rotating active biomotors
10.1039/C8SM00022K 2018-04-11 Although synchronization is a well-known physical phenomenon, experimental studies of its emergence in living bacterial cells are still scarce. The difficulty in generating a controlled scenario to detect synchronization has limited the experimental outcomes ... |

Determine electrospun morphologies from the properties of protein-polymer solutions
10.1039/C7SM02203D 2018-04-11 Integrating natural macromolecules, e.g. proteins, is a progressive trend to fabricate biocompatible sub-micrometer fibers with tunable diameters using electrospinning technique. The correlation between solution properties and electrospun morphologies is crit... |

Soft Electrodes Combining Hydrogel and Liquid Metal
10.1039/C8SM00337H 2018-04-11 Soft and stretchable materials play an important role in the emerging fields of soft robotics, human-machine interfaces, and stretchable electronics. Hydrogels are compelling materials because they are soft, chemically tunable, biocompatible, and ionically co... |

Adsorption of phospholipids at oil/water interfaces during emulsification is controlled by stress relaxation and diffusion
10.1039/C8SM00005K 2018-04-10 Adsorption of phosphatidylcholines at oil/water interfaces strongly deviates from spread monolayers at air/water surfaces. Understanding its nature and consequences could vastly improve applications in medical nanoemulsions and biotechnologies. Adsorption kin... |

Influence of molecular weight between crosslinks on the mechanical properties of polymers formed via ring-opening metathesis
10.1039/C7SM02407J 2018-04-10 The apparent molecular weight between crosslinks (Mc,a) in a polymer network plays a fundamental role in the network mechanical response. We systematically varied Mc,a independent of strong noncovalent bonding by using ring-opening metathesis polymerization (... |

Magnetically driven omnidirectional artificial microswimmers
10.1039/C8SM00230D 2018-04-10 We present an experimental realisation of two new artificial microswimmers that swim at low Reynolds number. The swimmers are externally driven with a periodically modulated magnetic field that induces an alternating attractive/repulsive interaction between t... |

A structural comparison of casein micelles in cow, goat and sheep milk using X-ray scattering
10.1039/C8SM00458G 2018-04-10 The casein micelle is a flexible construct, with its key structural components being casein proteins and colloidal calcium phosphate nanoclusters. According to literature, milk from different species exhibits differences in composition and physicochemical pro... |

Dual Marangoni effects and detection of traces of surfactants
10.1039/C8SM00266E 2018-04-10 We report controlled and tunable Marangoni flows resulting from concentration gradients that are induced by placing a droplet of volatile solute above the surface of a liquid. Condensation of the solute at the liquid surface results in a surface tension gradi... |
