Coexistence and transition between Cassie and Wenzel state on pillared hydrophobic surface (2009)

Koishi, Takahiro, Yasuoka, Kenji, Fujikawa, Shigenori, Ebisuzaki, Toshikazu, Zeng, Xiao Cheng

Water droplets on rugged hydrophobic surfaces typically exhibit one of the following two states: (i) the Wenzel state [Wenzel RN (1936) Ind Eng Chem 28:988-994] in which water droplets are in full...

Large-scale molecular-dynamics simulation of nanoscale hydrophobic interaction and nanobubble formation (2005)

Koishi, Takahiro, Yasuoka, Kenji, Ebisuzaki, Toshikazu, Yoo, S., Zeng, Xiao Cheng

We performed large-scale molecular-dynamics simulation of nanoscale hydrophobic interaction manifested by the formation of nanobubble between nanometer-sized hydrophobic clusters at constrained...

An 8.61 Tflop/s Molecular Dynamics Simulation for NaCl with a Special-Purpose Computer (2001)

Tetsu Narumi, Atsushi Kawai, Takahiro Koishi, High Performance, Biocomputing Team

We performed molecular dynamics (MD) simulation of 33 million pairs of NaCl ions with the Ewald summation and obtained a calculation speed of 8.61 Tflop/s. In this calculation we used a...
