2012 journal article

Bulky Adamantanethiolate and Cyclohexanethiolate Ligands Favor Smaller Gold Nanoparticles with Altered Discrete Sizes

ACS NANO, 6(6), 4903–4911.

By: P. Krommenhoek n, J. Wang*, N. Hentz*, A. Johnston-Peck, K. Kozek, G. Kalyuzhny*, J. Tracy* 

Contributors: P. Krommenhoek n, J. Wang*, N. Hentz*, A. Johnston-Peck, K. Kozek, G. Kalyuzhny*, J. Tracy* 

author keywords: steric effects; bulky ligands; magic sizes; discrete sizes; clusters; gold; thiol
MeSH headings : Adamantane; Crystallization / methods; Cyclohexanes / chemistry; Gold / chemistry; Ligands; Macromolecular Substances / chemistry; Materials Testing; Molecular Conformation; Nanoparticles / chemistry; Nanoparticles / ultrastructure; Particle Size; Sulfhydryl Compounds / chemistry; Surface Properties
TL;DR: Use of bulky ligands in the synthesis of metal nanoparticles (NPs) gives smaller core sizes, sharpens the size distribution, and alters the discrete sizes, which may also lead to the discovery of new discrete sizes in other systems. (via Semantic Scholar)

2011 journal article

Coating Alumina on Catalytic Iron Oxide Nanoparticles for Synthesizing Vertically Aligned Carbon Nanotube Arrays

ACS Applied Materials & Interfaces, 3(11), 4180–4184.

By: X. Wang n, P. Krommenhoek n, P. Bradford n, B. Gong n, J. Tracy n , G. Parsons n , T. Luo n, Y. Zhu n 

Contributors: X. Wang n, P. Krommenhoek n, P. Bradford n, B. Gong n, J. Tracy n , G. Parsons n , T. Luo n, Y. Zhu n 

author keywords: carbon nanotubes; nanoparticles; iron oxide; chemical vapor deposition; atomic layer deposition
MeSH headings : Aluminum Oxide / chemistry; Catalysis; Ferric Compounds / chemistry; Nanotechnology / instrumentation; Nanotubes, Carbon / chemistry
TL;DR: Comparison with uncoated NPs shows that the Al(2)O(3) coating effectively prevents the catalyst NPs from sintering and coalescing, resulting in improved control over VACNT growth. (via Semantic Scholar)
