Synthesis, Alignment, and Magnetic Properties of Monodisperse Nickel Nanocubes
Alec P. LaGrow,Bridget Ingham,Soshan Cheong,Soshan Cheong,Grant V. M. Williams,Grant V. M. Williams,C. Dotzler,C. Dotzler,Michael F. Toney,David A. Jefferson,Elena Cristina Corbos,Peter Trenton Bishop,James Cookson,Richard D. Tilley,Richard D. Tilley +14 more
TL;DR: High-resolution transmission electron microscopy and Synchrotron-based X-ray diffraction techniques showed the nickel nanocubes order into [100] aligned arrays, showing over 4 times enhancement in magnetic saturation compared to spherical superparamagnetic nickel nanoparticles.
Journal ArticleDOI
A Au/Cu2O–TiO2 system for photo-catalytic hydrogen production. A pn-junction effect or a simple case of in situ reduction?
Lutfan Sinatra,Alec P. LaGrow,Wei Peng,Ahmad R. Kirmani,Aram Amassian,Hicham Idriss,Osman M. Bakr +6 more
TL;DR: In this paper, photo-catalytic H 2 production from water has been studied over Au-Cu 2 O nanoparticles deposited on TiO 2 (anatase) in order to probe into both the plasmon resonance effect (Au nanoparticles) and the pn-junction at the Cu 2 O-TiO 2 interface.
Journal ArticleDOI
Visualizing the Cu/Cu2O Interface Transition in Nanoparticles with Environmental Scanning Transmission Electron Microscopy
TL;DR: Following the dynamic oxidation process in situ in real time with high-angle annular dark-field imaging in the ESTEM provides unique insights into redox mechanisms which are important to understanding and controlling the oxidation and reduction of copper-based nanoparticles.
Journal ArticleDOI
Unravelling the growth mechanism of the co-precipitation of iron oxide nanoparticles with the aid of synchrotron X-Ray diffraction in solution.
Alec P. LaGrow,Maximilian O. Besenhard,Aden Hodzic,Andreas Sergides,Lara K. Bogart,Asterios Gavriilidis,Nguyen T. K. Thanh +6 more
TL;DR: This work study in detail a co-precipitation synthesis with an abrupt increase in pH via the addition of sodium carbonate utilising a flow reactor and shows a distinct transition from an amorphous ferrihydrite phase to a mixture of magnetite-maghemite.
Journal ArticleDOI
Quantum confinement-tunable ultrafast charge transfer at the PbS quantum dot and phenyl-C₆₁-butyric acid methyl ester interface.

TL;DR: Investigation of charge transfer and separation at PbS QDs and phenyl-C61-butyric acid methyl ester interfaces using a combination of femtosecond broadband transient absorption (TA) spectroscopy and steady-state photoluminescence quenching measurements demonstrates that charge transfer rates at QD interfaces can be tuned by several orders of magnitude by engineering the QD size distribution.
