Solid–Liquid Interface Structure of Muscovite Mica in SrCl2 and BaCl2 Solutions
10.1021/acs.langmuir.8b00504 2018-03-30 The structure of the solid–liquid interface formed by muscovite mica in contact with two divalent ionic solutions (SrCl2 and BaCl2) is determined using in situ surface X-ray diffraction using both specular and non-specular crystal truncation rods. The 0.5 mon... |

Symmetrical Catalytically Active Colloids Collectively Induce Convective Flow
10.1021/acs.langmuir.8b00310 2018-03-30 Although much attention has focused on self-motile asymmetrical catalytically active “Janus” colloids as a route to enable new fluidic transport applications, the motion of symmetrical catalytically active colloids is less investigated. This is despite isotro... |

Photoswitchable Layer-by-Layer Coatings Based on Photochromic Polynorbornenes Bearing Spiropyran Side Groups
10.1021/acs.langmuir.8b00137 2018-03-30 Herein, we present the synthesis of linear photochromic norbornene polymers bearing spiropyran side groups (poly(SP-R)) and their assembly into layer-by-layer (LbL) films on glass substrates when converted to poly(MC-R) under UV irradiation. The LbL films wer... |

Dynamic Scaling of Exosome Sizes
10.1021/acs.langmuir.7b04080 2018-03-30 A model is proposed for characterizing exosome size distributions based on dynamic scaling of domain growth on the limiting membrane of multivesicular bodies in the established exosome biogenesis pathway. The scaling exponent in this model captures the asymme... |
