New Perspectives on Iron Uptake in Eukaryotes
Autor: Harry G. Sherman, Carolyn Jovanovic, Snow Stolnik, Kim Baronian, Alison J. Downard, Frankie J. Rawson
Publikováno v: Frontiers in Molecular Biosciences, Vol 5 (2018)
All eukaryotic organisms require iron to function. Malfunctions within iron homeostasis have a range of physiological consequences, and can lead to the development of pathological conditions that can result in an excess of non-transferrin bound iron

Para-Fluoro-Thiol Reaction on Anchor Layers Grafted from an Aryldiazonium Salt: A Tool for Surface Functionalization with Thiols
Autor: Ting Wu, Christopher M. Fitchett, Alison J. Downard
Publikováno v: Langmuir. 37:11397-11405
A new coupling reaction, the para-fluoro-thiol (PFT) reaction, activated by base at room temperature, is reported for carbon surface functionalization. 4-Nitrothiophenol (4-NTP) and (3-nitrobenzyl)mercaptan (3-NBM) were coupled to pentafluorophenyl (

Electroreduction of Aryldiazonium Ion at the Polar and Non‐Polar Faces of ZnO: Characterisation of the Grafted Films and Their Influence on Near‐Surface Band Bending
Autor: Martin W. Allen, Roger J. Reeves, Alison J. Downard, Alexandra R. McNeill, Rodrigo F. Martinez-Gazoni
Publikováno v: ChemPhysChem.
ZnO is a strong candidate for transparent electronic devices due to its wide band gap and earth-abundance, yet its practical use is limited by its surface metallicity arising from a surface electron accumulation layer (SEAL). The SEAL forms by hydrox

Building Tailored Interfaces through Covalent Coupling Reactions at Layers Grafted from Aryldiazonium Salts
Autor: Alison J. Downard, Ting Wu, Paula A. Brooksby, Christopher M. Fitchett
Publikováno v: ACS applied materialsinterfaces. 13(10)
Aryldiazonium ions are widely used reagents for surface modification. Attractive aspects of their use include wide substrate compatibility (ranging from plastics to carbons to metals and metal oxides), formation of stable covalent bonding to the subs

Relationship between the hydroxyl termination and band bending at (2¯01)β−Ga2O3 surfaces
Autor: Martin W. Allen, L. Carroll, Alison J. Downard, D. A. Evans, Roger J. Reeves, S. Astley, Jonty I. Scott, Rodrigo M. Gazoni
Publikováno v: Physical Review B. 102
Synchrotron x-ray photoelectron spectroscopy was used to explore the relationship between the hydroxyl termination and band bending at the $(\overline{2}01)$ surface of $\ensuremath{\beta}\text{\ensuremath{-}}\mathrm{G}{\mathrm{a}}_{2}{\mathrm{O}}_{3

The effect of covalently bonded aryl layers on the band bending and electron density of SnO2 surfaces probed by synchrotron X-ray photoelectron spectroscopy
Autor: Martin W. Allen, Alexandra R. McNeill, Joel C. Schuurman, Jonty I. Scott, Roger J. Reeves, Alison J. Downard, Rodrigo F. Martinez-Gazoni
Publikováno v: Physical Chemistry Chemical Physics. 21:17913-17922
Tin(IV) dioxide (SnO2) is a technologically important transparent conducting oxide with high chemical stability. In air, the SnO2 surface is terminated with hydroxyl groups which cause the electronic bands to bend downward at the surface capturing a

Synchrotron X-ray Photoelectron Spectroscopy Study of Electronic Changes at the ZnO Surface Following Aryldiazonium Ion Grafting: A Metal-to-Insulator Transition
Autor: Alison J. Downard, Rodrigo M. Gazoni, Martin W. Allen, Roger J. Reeves, Kalib J. Bell, Adam R. Hyndman, Alexandra R. McNeill
Publikováno v: The Journal of Physical Chemistry C. 122:12681-12693
ZnO is a member of a small class of semiconductors that includes In2O3, SnO2, CdO, and InN, whose surfaces are highly unusual because their electronic bands bend downward to form a quantized potential well in which a two-dimensional electron gas is c

Measuring the Capacitance at Few- and Many-Layered Graphene Electrodes in Aqueous Acidic Solutions
Autor: Paula A. Brooksby, Anna K. Farquhar, Alison J. Downard
Publikováno v: The Journal of Physical Chemistry C. 122:6103-6108
The differential capacitance of 1–2 layered and 6–7 layered graphene (LG) was measured in aqueous 0.01, 0.1, 1.0, and 3 M perchloric and sulfuric acid solutions. The total measured capacitance was evaluated for approx. ±500 mV either side of the
