Floating and Tether-Coupled Adhesion of Bacteria to Hydrophobic and Hydrophilic Surfaces
10.1021/acs.langmuir.7b04331 2018-04-18 Models for bacterial adhesion to substratum surfaces all include uncertainty with respect to the (ir)reversibility of adhesion. In a model, based on vibrations exhibited by adhering bacteria parallel to a surface, adhesion was described as a result of reversi... |

A Concentration-Dependent Insulin Immobilization Behavior of Alkyl-Modified Silica Vesicles: The Impact of Alkyl Chain Length
10.1021/acs.langmuir.8b00377 2018-04-18 The insulin immobilization behaviors of silica vesicles (SV) before and after modification with hydrophobic alkyl -C8 and -C18 groups have been studied and correlated to the grafted alkyl chain length. In order to minimize the influence from the other structu... |

Numerical Study of Surfactant Dynamics during Emulsification in a T-Junction Microchannel
10.1021/acs.langmuir.8b00123 2018-04-18 Microchannel emulsification requires large amounts of surfactant to prevent coalescence and improve emulsions lifetime. However, most numerical studies have considered surfactant-free mixtures as models for droplet formation in microchannels, without taking i... |

Bifunctionality of Iminodiacetic Acid-Modified Lysozyme on Inhibiting Zn2+-Mediated Amyloid β-Protein Aggregation
10.1021/acs.langmuir.8b00254 2018-04-17 Aggregation of amyloid β-proteins (Aβ) mediated by metal ions such as Zn2+ has been suggested to be implicated in the progression of Alzheimer’s disease (AD). Hence, development of bifunctional agents capable of inhibiting Aβ aggregation and modulating metal-... |

Maximum Spreading and Rebound of a Droplet Impacting onto a Spherical Surface at Low Weber Numbers
10.1021/acs.langmuir.8b00625 2018-04-17 The spreading and rebound patterns of low-viscous droplets upon impacting spherical solid surfaces are investigated numerically. The studied cases consider a droplet impinging onto hydrophobic and superhydrophobic surfaces with various parameters varied throu... |

Spontaneous Spreading of a Droplet: The Role of Solid Continuity and Advancing Contact Angle
10.1021/acs.langmuir.8b00522 2018-04-17 Spontaneous spreading of a droplet on a solid surface is poorly understood from a macroscopic level down to a molecular level. Here, we investigate the effect of surface topography and wettability on spontaneous spreading of a water droplet. Spreading force i... |

Passivation of Plasmonic Colors on Bulk Silver by Atomic Layer Deposition of Aluminum Oxide
10.1021/acs.langmuir.8b00210 2018-04-16 We report the passivation of angle-independent plasmonic colors on bulk silver by atomic layer deposition (ALD) of thin films of aluminum oxide. The colors are rendered by silver nanoparticles produced by laser ablation and redeposition on silver. We then app... |

Formation of Liquid Marbles Using pH-Responsive Particles: Rolling vs Electrostatic Methods
10.1021/acs.langmuir.7b04204 2018-04-16 Aqueous dispersions of micrometer-sized, monodisperse polystyrene (PS) particles carrying pH-responsive poly[2-(diethylamino)ethyl methacrylate] (PDEA) colloidal stabilizer on their surfaces were dried under ambient conditions at pH 3.0 and 10.0. The resultin... |
