Fire assay is an established and proven method for testing the purity of gold jewelry and other objects. Nevertheless, it is a destructive and time-consuming process requiring the use of hazardous chemicals. X-ray fluorescence has emerged as a non-destructive alternative to the fire assay method, with comparable accuracy in just minutes. XRF instrumentation is now available in portable units ideally suited for countertop use in retail environments for accurate testing of any precious metal. In a test against two different refineries using fire assay to evaluate two gold ingots from the same melt, an XRF analyzer provided results just as accurate as one refinery, and even more accurate than the second refinery. The test results provided in this article were performed using the Thermo Scientific? Niton? DXL Precious Metal Analyzer.

For many years Raman spectroscopy has been applied to characterisationof polymers. However, the applications have tended to be research-oriented,rather than designed for routine analysis. With the revolutionarydevelopments in Raman instrumentation, it is now possible to acquirespectra quite rapidly on equipment that is much more affordable and easierto use than in the past. The following will summarise how Ramanspectroscopy has been used successfully for the study of polymers,and will indicate which effects can be monitored on a routine basis forindustrial analytical purposes.

Thanks to confocal Raman spectroscopy we have been able to investigate in vivo the epidermis chemical composition in its thickness. In depth measurements allowed us to observe modifications of the relative concentration of some components (water, proteins) depending on the depth in the skin and on its state of hydration.The use of larger numerical aperture objectives would be helpful to emphasize the in-depth variations because of the possible gain in axial resolution and therefore in-depth discrimination. Indeed, the operator could then probe in depth with a smaller step size.As a possible gain on the above measurements, the use of more powerful commercially available NIR diode lasers would yield up to ten times more laser power at the sample (60-80 mW) and would result in a tremendous improvement in terms of signal collection and integration time.?

ΑIIbβ3 is a key mediator in the thrombotic process and has been studied extensively. This current work reports the first Raman spectrum of the protein, and examines changes in conformation during activation. Using three common agonists (DTT, Mn(II) and EDTA), the results indicate that in each case activation is caused by reduction of disulfide links, but suggests that different disulfides are activated according to the reagent used. The histopathological correlation to these findings has yet to be determined.

Reducing the deleterious effect of Vortex Induced Vibrations (VIV) in marine risers is animportant task for ocean engineers and many competing factors exist in the design ofVIV suppression devices. This thesis explores the experimental minimization of the dragforce and the disruption of v0l1ex formation by utilizing VIV suppression devices.Two series of tests are conducted-both utilizing separate testing designs. The first testsare the flexible cylinder experiments, detailed in Chapter 2, which determine the dragforce and vibration amplitude of numerous, original testing configurations. The secondseries of tests are the rigid cylinder, PIV experiments, detailed in Chapter 3. These testsmeasure both the drag force on the cylinder and the oscillating component of the liftforce, the latter of which is a good indication of v011ex formation. The Chapter 3 testsalso image the test section wake-providing helpful insight into the physical process ofvortex formation.In brief, this thesis presents a detailed description and results of the two series of originalVIV suppression tests. Many original configurations are tested, and the results arecontained herein.

The present study of mediaeval pigments using micro-Raman spectroscopy provides important information on the inorganic and organic type of pigments used in the wall paintings in the remains of the church in Skopsko Kale (Skopje Fortress). In general, the variety of pigments found and their allocation to different time periods confirms the assumption of the archaeologists that the sacral building has been reconstructed in the 19th century. Mostrewarding was the analysis of the yellow pigments: Indian yellow, in use in 15th―19th century.All this information documented an important stage in the life of the Skopje Fortress. Despite the fully applied political and military power of the Ottoman Empire, the renovation confirms a subtle coexistence of the two communities, Muslim and Christian, in the city.

Raman spectra, in conjunction with Multivariate (Chemometric) Analysis, have been demonstrated to provide real-time information on the progress of a polymerisation reaction. As shown by this example, these results can provide unexpected information on the details of the reaction. in this case, the inequivalent reaction rates of the two monomers. Such information ultimately enables the process engineer to optimise his process.

Developing Multiple Reaction Monitoring (MRM)-based screening methods for routine analysis is a common operation in analytical laboratories. To maximize analytical performance, researchers often need to optimize many LC and MS parameters. An intelligent software could assist method development from several aspects, such as cutting method development time, automating workflow, auto-selecting optimal parameters, tracking system to meet compliance requirement, etc.

The effect on fuel consumption and emissions of switching from two-valve to single-valve EIVC operation inorder to generate swirl intake structures in a four-valve, pent-roof gasoline direct injection (GDI) engine hasbeen investigated. Mie imaging of the fuel spray propagation, along with PIV measurements of the intake flowfield have been taken in an optical engine, and fuel economy and emissions measurements have been made on athermodynamic engine with identical geometry and ancillary systems.The measurements show that fuel economy can be improved substantially when EIVC valve operation is employed,and results differ when only a single inlet valve is activated. Bulk swirl structures are generated in theengine cylinder which affect the atomisation and transportation of the fuel spray and engine performance. Forfuel injection after the inlet valve closing point, the reduction in shear forces and mixing from the intake airstructures is sufficient to cause engine misfires.

The Raman spectra of the various forms of elemental carbon are very sensitive to the type of nearest neighbour bonding, and to intermediate and long range order. In many cases Raman spectroscopy is the technique of choice for characterisation of carbon materials. Correlation of Raman spectral features with tribological properties can facilitate the deposition of carbon films.

This note demonstrates that depending on the configuration of the Raman system used, one can extract different types of information about Carbon Nanotubes. A multiexcitation, low frequency, high spectral and spatial resolution Raman system is the best solution to collect the maximum information. Raman has shown a high potential in characterising the SWCNTs ‘ structure. The correlation between knowledge about structure with physical and chemical properties about the tubes make the technique extremely powerful to control the quality of the SWCNTs for specific applications. Raman spectrometer capabilities like spatial resolution, spectral resolution and excitation wavelength versatility have been examined. Beside Raman, preliminary fluorescence studies are describing the potential of the technique.

The DiskRam has been designed to automate the collection of Raman spectra from hard carbon coatings on computer hard disk media and the extraction of parameters that are well correlated with the properties of the films. The extracted information is output in spreadsheet format for SPC at a manufacturing facility.

The Raman spectra of elemental carbon materials are known to be sensitive to polymorphy. For hard carbon films, the spectra of amorphous and diamond-like carbons can be band-fit to separate the contributions of the "graphitic carbon" (G band) from the "disordered carbon" (D band). The spectral behaviour of carbon films has been empirically correlated with thin film physical properties such as hardness, durability, optical transparency, electrical conductivity, thermal conductivity and corrosion resistance, and can be ofuse for prediction of these properties without extensive alternative testing.

Raman image (Figure 1) from a thin film of azobenzene-containing polymer thin film (300 nm) that is periodically structured (periodicity of ~1 µ m). Raman measurements were recorded with a Labram HR 800 (HORIBA JobinYvon) spectrometer combined with an inverted microscope (Olympus IX 71) and a X,Y Piezoelectric stage to position the sample with the best accuracy and repeatability. A 100X, 0.9 NA microscope objective was used. A Raman spectrum (Fig. 2) was recorded every 100 nm along the X and Y directions with an integration time of 5 seconds per spectrum (λ excitation=752.4 nm). The variation of the Raman signal was integrated over the [10601180]cm-1 spectral domain (Figure 3). It must pointed out that details on the Raman profile are obtained with a spatial resolution better than λ /2 (at the diffraction limit).
