Benson Sarah; Lennard Christopher; Maynard Philip; Hill Delores; Andrew Anita; Neal K; Stuart-Williams H; Hope J; Walker G; Roux Claude (Wiley-Blackwell Publishing, Inc, 2010)

Comparability of data over time and between laboratories is a key issue for consideration in the development of global databases, and more broadly for quality assurance in general. One mechanism that can be utilized for ...
Forensic analysis of explosives using isotope ratio mass spectrometry (IRMS) - Preliminary study on TATP and PETN

Benson Sarah; Lennard Chris; Maynard Philip; Andrews Anita; Hill David; Roux Claude (Forensic Science Society, 2009)

The application of isotopic techniques to investigations requiring the provision of evidence to a Court is limited. The objective of this research was to investigate the application of light stable isotopes and isotope ...
Forensic applications of chemical imaging: Latent fingerprint detection using visible absorption and luminescence

Wallace - Kunkel Christie; Exline David; Lennard Christopher; Roux Claude; Treado Patrick J; Nelson Matthew (Australian and New Zealand Academy of Management, 2005)

Chemical imaging technology is a rapid examination technique that combines molecular spectroscopy and digital imaging, providing information on morphology, composition, structure, and concentration ofa material. Among ...
Forensic applications of infrared chemical imaging: Multi-layered paint chips

O'Leary Robyn; Bojko Katherine; Roux Claude; Lennard Christopher; Reedy Brian (Australian Health Promotion Association, 2007)

This paper examines the potential of infrared chemical (hyperspectral) imaging as a technique for the forensic analysis of automotive paint chips in particular, and multicomponent (e.g., layered) samples in general. ...
Forensic classification of ballpoint pen inks using high performance liquid chromatography and infrared spectroscopy with principal components analysis and linear discriminant analysis

Kher Ashwini; Mulholland Mary; Green Elinore; Reedy Brian (Elsevier, 2006)

Several varieties of blue ballpoint pen inks were analyzed by high performance liquid chromatography (HPLC) and infrared spectroscopy (IR). The chromatographic data extracted at four wavelengths (254, 279, 370 and 400 nm) ...
Formation and Characterization of an Aqueous Zirconium Hydroxide Colloid

Southon Peter; Bartlett John; Woolfrey James; Ben-Nissan Besim (American Chemical Society, 2002)

Among the wide variety of routes reported for the chemical synthesis of zirconia, the development of simple, aqueous sol-gel technology is of considerable interest for industrialscale applications. In this study, zirconium ...
Formation modulation and adaptive twinning of martensite in the Au7Cu5Al4 shape memory system

Cortie Michael; Levey F (Elsevier, 2002)

The Au7Cu5Al4 b electron phase transforms displacively from an L21 parent to a nominally body-centred tetragonal martensite with c/a<1. The compound is of interest because it has the potential to serve as an 18 carat shape ...
A Fourier transform Raman study of water absorption by Nylon 6

Stuart Barbara (Springer Berlin, 1994)

The changes to Fourier transform Raman spectra of Nylon 6 due to the presence of water have been examined. It is postualted that water molecules disrupt the inter-chain hydrogen-bonding which exists in the polyamide; water ...
A Fourier transform Raman study of water sorption by Kevlar-49

Stuart Barbara (Springer Berlin, 1995)

The Fourier transform (FT) Raman spectrum of poly (p-phenylene terephthalamide) (Kevlar-49) is reported, Additional bands, not observed in the conventional Raman spectrum have been assigned. The changes to the FT-Raman ...
FTIR of Biomolecules

Stuart Barbara (Wiley, 2004)
FTIR Study of the Thermal Degradation of poly(vinyl alcohol)

Guerbois Jean-Pierre; Thomas Paul; Briscoe Brian; Russell G (Springer, 2002)

The degradation of poly(vinyl alcohol) was investigated using TG analysis and Fourier transform infrared spectroscopy to determine the effect of atmosphere on the process of degradation. In the spectra, four vibrational ...
Functional heterogeneity of the fucoxanthins and fucoxanthin-chlorophyll proteins in diatom cells revealed by their electrochromic response and fluorescence and linear dichroism spectra

Szabo Milan; Premvardhan Lavanya; Lepetit Bernard; Goss Reimund; Wilhelm Christian; Garab Gyozo (Elsevier, 2010)

Electrochromic transient, liner dichroism and 77 K fluorescence excitation and emission spectra show that fucoxanthins and fucoxanthin-chlorophyll proteins exhibit functional heterogeneity in diatom cells.
The future for electrocoagulation as a localised water treatment technology

Holt Peter; Barton Geoff; Mitchell Cynthia (Elsevier, 2005)

Electrocoagulation is an electrochemical method of treating polluted water whereby sacrificial anodes corrode to release active coagulant precursors (usually aluminium or iron cations) into solution. Accompanying electrolytic ...
Glass breaks : from nickel sulfide inclusions

Ray Abhi; Jacob Leon (National Glass Association, 2006)
Glycation of low-density lipoprotein results in the time- dependent accumulation of cholesteryl esters and apolipoprotein B-100 protein in primary human monocyte-derived macrophages

Brown Bronwyn; Rashid Imran; Van Reyk David; Davies Michael (Blackwell Science, 2002)
Gold NanosphereAntibody Conjugates for Hypothermal Therapeutic Applications

Pissuwan Dakrong; Cortie C; Valenzuela Stella; Cortie Michael (World Gold Council, 2007)

Gold nanoparticles can be conjugated with antibodies or other proteins, and the resulting composite particles will selectively attach to various kinds of biological material. Although exploitation of this for staining ...
Granular activated carbon (GAC) adsorptionphotocatalysis hybrid system in the removal of herbicide from water

Areerachakul Nathaporn; Vigneswaran Saravanamuth; Ngo Huu Hao; Kandasamy Jaya (Elsevier Science Bv, 2007)

The performance of the granular activated carbon (GAC) fixed bed adsorption, the continuous photocatalysis systems and a combination of the two were studied to evaluate their capabilities in removing the herbicide of ...
