Journal ArticleDOI
Structural diversity in binary nanoparticle superlattices
Elena V. Shevchenko,Dmitri V. Talapin,Dmitri V. Talapin,Nicholas A. Kotov,Stephen O'Brien,Christopher B. Murray +5 more
TL;DR: It is demonstrated that electrical charges on sterically stabilized nanoparticles determine B NSL stoichiometry; additional contributions from entropic, van der Waals, steric and dipolar forces stabilize the variety of BNSL structures.
Journal ArticleDOI
Copper oxide nanocrystals.
Ming Yin,Chun Kwei Wu,Yongbing Lou,Clemens Burda,Jeffrey T. Koberstein,Yimei Zhu,Stephen O'Brien +6 more
TL;DR: This work has developed a method for preparing highly uniform monodisperse nanocrystals of Cu(2)O, and confirmed the thin layer of CuO, which is blue-shifted, and appears to increase in energy as a function of decreasing particle size.
Journal ArticleDOI
Three-dimensional binary superlattices of magnetic nanocrystals and semiconductor quantum dots
TL;DR: This study reports the self-assembly of PbSe semiconductor quantum dots and Fe2O3 magnetic nanocrystals into precisely ordered three-dimensional superlattices with potentially tunable optical and magnetic properties.
Journal ArticleDOI
Covalently Bridging Gaps in Single-Walled Carbon Nanotubes with Conducting Molecules
Xuefeng Guo,Joshua P. Small,Jennifer E. Klare,Yiliang Wang,Meninder Purewal,Iris W. Tam,Byung Hee Hong,Robert Caldwell,Limin Huang,Stephen O'Brien,Jiaming Yan,Ronald Breslow,Shalom J. Wind,James Hone,Philip Kim,Colin Nuckolls +15 more
TL;DR: This work describes a method to wire molecules into gaps in single-walled carbon nanotubes (SWNTs) and shows how to install functionality in the molecular backbone that allows the conductance of the single-molecule bridges to switch with pH.
Journal ArticleDOI
Structural Characterization of Self-Assembled Multifunctional Binary Nanoparticle Superlattices
TL;DR: A large variety of different binary superlattices are demonstrated, their detailed structural characterization is provided, and the role of energetic and kinetic factors in the cocrystallization process is discussed.
