Journal ArticleDOI
Prediction of TiO2 nanoparticle phase and shape transitions controlled by surface chemistry.
TL;DR: It has been found that surfaces representing acidic and alkaline conditions have a significant influence on both the shape of the nanocrystals and the anatase-to-rutile transition size.
Journal ArticleDOI
Observation and control of blinking nitrogen-vacancy centres in discrete nanodiamonds
Carlo Bradac,Torsten Gaebel,N. Naidoo,Matthew Sellars,Jason Twamley,Louise J. Brown,Amanda S. Barnard,Taras Plakhotnik,Andrei V. Zvyagin,James R. Rabeau +9 more
TL;DR: The first direct observation of nitrogen-vacancy centres in discrete 5-nm nanodiamonds at room temperature is reported, including evidence for intermittency in the luminescence (blinking) from the nanod diamonds, and it is shown that it is possible to control this blinking by modifying the surface of the nanODiamonds.
Journal ArticleDOI
A model for the phase stability of arbitrary nanoparticles as a function of size and shape
Amanda S. Barnard,Peter Zapol +1 more
TL;DR: It is shown that diamond nanocrystal morphology is markedly different from silicon and germanium.
Journal ArticleDOI
Nanogold: A Quantitative Phase Map
TL;DR: This work presents the first quantitative equilibrium phase map for gold nanoparticles together with experimental verification, based on relativistic ab initio thermodynamics and in situ high-resolution electron microscopy at elevated temperatures.
Journal ArticleDOI
Naturally occurring iron oxide nanoparticles: morphology, surface chemistry and environmental stability
Haibo Guo,Amanda S. Barnard +1 more
TL;DR: In this article, a review of several phases (ferrihydrite, goethite, hematite, magnetite, maghemite, lepidocrocite, akaganeite and schwertmannite) commonly found in water, soils and sediments is presented.
