Ab Initio And Empirical Studies On The Asymmetry Of Molecular Currentvoltage Characteristics

Hoft Rainer; Armstrong Nicholas; Ford Michael; Cortie Michael (Institute of Physics Publishing, 2007)
Analysis of admixed CeO2 nanoparticles via TEM and x-ray diffraction techniques

Vella A; Whitley Rhys; Armstrong Nicholas; Dowd Annette; Cline James (Australian Institute of Physics, 2006)

The techniques used to identify nanoparticle size and shape characteristics are of vital importance in the development of functional nanoparticles. Each technique offers different advantages; this work compares the two ...
Bayesian analysis of ceria nanoparticles from line profile data

Armstrong Nicholas; Dowd Annette; Cline James; Kalceff Walter (International Centre for Diffraction Data, 2005)

A Bayesian/Maximum entropy (MaxEnt) method is applied to quantify the broadening of xray line profiles in terms of the nanocrystallite size effects in ceria. The analysis is in general agreement with transmission electron ...
A Bayesian/Maximum Entropy Method for Certification of a NanocrystallineSize NIST Reference Material

Kalceff Walter; Cline James; Armstrong Nicholas; Bonevich John (Springer Verlag, 2004)
Cathodoluminescence as a method of extracting detailed information from nanophotonics systems: a study of silicon nanocrystals

Phillips Matthew; Ton-That Cuong; Dowd Annette; Armstrong Nicholas; Johansson Birger (SPIE-Int Society Optical Engineering, 2006)

We investigated Si nanocaystal samples produced by high dose 600 keV Si+ implantation of fused silica and annealing using cathodoluminescence (CL). CL spectra collected under 5-25 keV electron irradiation show similar ...
Determining the dislocation contrast factor for x-ray line profile analysis

Armstrong Nicholas; Lynch Peter (Springer Verlag, 2004)
Exploring The Performance Of Molecular Rectifiers Limitations And Factors Affecting Molecular Rectification

Armstrong Nicholas; Hoft Rainer; Mcdonagh Andrew; Cortie Michael; Ford Michael (American Society of Civil Engineers, 2007)
A modified Jarvis-Stewart model for predicting stand-scale transpiration of an Australian native forest

Yunusa Isa; Macinnis-Ng Catriona; Whitley Rhys; Armstrong Nicholas; Zeppel Melanie; Eamus Derek (Springer, 2008)

Rates of water uptake by individual trees in a native Australian forest were measured on the Liverpool Plains, New South Wales, Australia, using sapflow sensors. These rates were up-scaled to stand transpiration rate ...
X-ray diffraction analysis on crystallite development of nanostructured aluminium

Meijer Elisabeth; Armstrong Nicholas; Yeung Wing (SciTec Publications Ltd, 2006)

This study is to investigate the crystallite development in nanostructured aluminium using x-ray line broadening analysis. Nanostructured aluminium was produced by equal channel angular extrusion at room temperature to ...
X-ray diffraction characterisation of nanoparticles size and shape distributions: application to bimodal distributions

Armstrong Nicholas; Kalceff Walter; Cline James; Bonevich John; Lynch Peter; Tang Chiu; Thompson Steve (Australian Institute of Physics, 2004)

We present a novel Bayesian/Maximum Entropy method to detect and resolve the modal characteristics of size distributions from x-ray diffraction line profiles. To our knowledge, none of the existing alternative methods ...
