Published Papers

Yuki Uematsu, Kengo Chida, Hiroki Matsubara
Colloids and Interface Science Communications   27 45-48   Nov 2018
© 2018 Elsevier B.V. The Jones-Ray effect is an anomalous minimum in the surface tension of aqueous electrolytes at millimolar salt concentrations. We experimentally demonstrated that intentionally added ionic surfactants induce the Jones-Ray effe...
Yuhei Tokiwa, Hiromu Sakamoto, Takanori Takiue, Makoto Aratono, Hiroki Matsubara, Colin D. Bain
Langmuir   34 6205-6209   May 2018
Copyright © 2018 American Chemical Society. Penetration of alkane molecules into the adsorbed film of a cationic surfactant gives rise to a surface freezing transition at the alkane-water interface upon cooling. In this paper, we show that surface...
Hiroki Matsubara, Makoto Aratono
Langmuir      Apr 2018
© 2018 American Chemical Society. This review addresses a variety of unique macroscopic-scale and colloidal-scale interfacial phenomena, such as wetting transitions of oil droplets into molecularly thin films, spontaneous merging and splitting of ...
Shusaku Ueno, Yuichi Takajo, Shunsuke Ikeda, Ryo Takemoto, Yosuke Imai, Takanori Takiue, Hiroki Matsubara, Makoto Aratono
Colloid and Polymer Science   296 781-798   Apr 2018
© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. We investigated the surface dilational viscoelasticities of aqueous solutions of dihexanoyl-phosphastidylcholine (DC6PC) and dioctanoyl-phosphastidylcholine (DC8PC), dodecyltrimethylam...
Hiroki Matsubara, Jo Otsuka, Bruce M. Law
Langmuir   34 331-340   Jan 2018
© 2017 American Chemical Society. The line tension for a nanoparticle (NP) at the air-liquid surface can be determined by examining the variation in NP solution surface tension with bulk NP concentration. In this publication the variation in line ...
Yosuke Imai, Yuhei Tokiwa, Shusaku Ueno, Hajime Tanida, Iwao Watanabe, Hiroki Matsubara, Takanori Takiue, Makoto Aratono
Bulletin of the Chemical Society of Japan   91 1487-1494   Jan 2018
© 2018 The Chemical Society of Japan. Competitive binding of binary mixed counterions to the headgroups of adsorbed surfactant films has been investigated at solution surfaces by total reflection X-ray absorption fine structure (XAFS) spectroscopy...
Miyako Tsuura, Aya Shuto, Shinya Hiraki, Yosuke Imai, Hiroyasu Sakamoto, Hiroki Matsubara, Makoto Aratono, Hajime Tanida, Kiyofumi Nitta, Tomoya Uruga, Takanori Takiue
Colloids and Surfaces A: Physicochemical and Engineering Aspects   525 31-37   Jul 2017
© 2017 Elsevier B.V. The surface freezing (SF) of liquid 6-perfluorohexyl hexanol (F6H6OH)–1-dodecanol (C12OH) mixture was studied by surface tension, external reflection absorption FTIR (ERA-FTIR), and X-ray reflectivity (XR) measurements. The su...
Bruce M. Law, Sean P. McBride, Jiang Yong Wang, Haeng Sub Wi, Govind Paneru, Santigo Betelu, Baku Ushijima, Youichi Takata, Bret Flanders, Fernando Bresme, Hiroki Matsubara, Takanori Takiue, Makoto Aratono
Progress in Surface Science   92 1-39   Feb 2017
© 2016 Elsevier Ltd In this review we examine the influence of the line tension τ on droplets and particles at surfaces. The line tension influences the nucleation behavior and contact angle of liquid droplets at both liquid and solid surfaces and...

International Journal of Nanotechnology   13 734-747   Jan 2016
Copyright © 2016 Inderscience Enterprises Ltd. We have previously studied the wetting behaviour of hexadecane (C16) lens on the dodecyltrimethylammonium bromide (DTAB) aqueous solution from interfacial tensiometry and ellipsometry. It is found tha...
S. Hiraki, T. Goto, H. Tanida, K. Nitta, T. Ina, T. Uruga, H. Matsubara, M. Aratono, T. Takiue
Colloids and Surfaces A: Physicochemical and Engineering Aspects   482 454-463   Oct 2015
© 2015 Elsevier B.V. The adsorbed film of n-tetradecylphosphocholine (C14PC) at the tetradecane (C14)/aqueous solution (W) interface was studied by interfacial tensiometry and X-ray reflection (XR). The interfacial tension γ was measured as a func...
