Abstract:

Dans cette thèse, nous avons examiné les propriétés spectrales de l’anhydride sulfureux. Les spectres FTIR expérimentaux de nombreux isotopologues du dioxyde de soufre, 32S16O2, 34S16O2, 32S18O2 et 32S16O18O, ont été enregistrés pour la première fois dans les régions des bandes fondamentales, «chaudes», harmoniques et de combinaison. La grande variabilité des conditions expérimentales a permis d’observer et d’identifier pour la première fois des transitions appartenant aux ban¬des ro-vibrationnelles suivantes : 3v2, 3v2 - v2, 2v2 - v2 bandes de 32S16O2 ; 2v2 - v2 bande de 34S16O2 ; v1 + v2, v2

Abstract:

This diploma thesis is about forensic multivariate soil analysis in the localities Ostrava and Třinec. A total of 52 samples were taken in the areas near metallurgical companies. These samples were measured for concentrations of chromium, manganese, copper, nickel, lead, mercury and zinc. Mercury concentration was analysed using AMA 254 device. The remaining metals were determined by flame atomic absorption spectrometry (F–AAS). Additionally, IR spectra were acquired by Fourier transform infrared spectroscopy (FTIR) using diffusion reflectance technique (DRIFT). In the end the results were use

Abstract:

One of the challenges in the structural biological community is processing the wealth of protein data being produced today; therefore, the use of computational tools has been incorporated to speed up and help understand the structures of proteins, hence the functions of proteins. In this thesis, protein structure investigations were made through the use of Multivariate Analysis (MVA), and Fourier Transformed Infrared (FTIR), a form of vibrational spectroscopy. FTIR has been shown to identify the chemical bonds in a protein in solution and it is rapid and easy to use; the spectra produced from

Globular proteins are important ingredients in many food formulations because of their nutritional value and their various functional properties such as gel formation. Proteins form gels by polymerization into a three-dimensional matrix. The rheological properties of the resulting viscoelastic solids can be obtained by Instron measurements.

Abstract:

<p> Compositional analysis of reservoir rock is a vital aspect of oil exploration and production activities. In a broad sense, knowing the mineral composition of a reservoir can help with characterization and interpretation of depositional environments. On a smaller scale, identifying mineralogy helps calibrate well logs, identify formations, design drilling and completion programs, and screen for intervals with potential problem minerals, such as swelling clays. The petroleum industry utilizes two main methods to find compositional mineralogy, x-ray diffraction (XRD) and thin section analysis

Currently there is no known method for accurately measuring the temperature of the gas phase of combustion products within a solid fuel flame. The industry standard is a suction pyrometer and thermocouple which is intrusive, both spatially and temporally averaging, and difficult to use.

This method was demonstrated along a 0.75m line of sight, averaged over 1 minute in the products of a natural gas flame but has the potential to produce a spatial resolution

Abstract:

The Maya of Central America developed a complex society: among their many achievements they developed a writing system, complex calendar and were prolific builders. The buildings of their large urban centres, such as Copan in Honduras, were decorated with painted stucco, moulded masks, carving and elaborate murals, using a range of coloured pigments. In this study the paints used on the buildings of Copan and some ceramic sherds have been investigated, non-destructively, using micro-Raman spectroscopy, micro-ATR infrared spectroscopy, environmental scanning electron microscopy with energy di

碩士<br>國立中央大學<br>物理研究所<br>91<br>Abstract Experimental results on the spectral identification of new infrared absorption features and the changes of their absorbances produced through vacuum ultraviolet-extreme ultraviolet(VUV-EUV) photon-induced chemical reactions in the H2O-NH3-CO2 mixed ices at 16K are obtained. The compositions, i.e., H2O:NH3:CO2= 6:1:1 were chosen in this work. Zeroth order white light from the SEYA beamline at Synchrotron Radiation Research Center (SRRC) in Hsinchu was used to provide required VUV-EUV photons. A FTIR spectrometer was employed to obtain the in-situ IR spe

Meanwhile, there are also many particles (with energy to some degree) that ejected by other stars in the universe, like the solar wind of the solar system. When bombarded with these energetic particles, the molecule structure of the interstellar ice could be changed and produce org

In outer space environment, the temperature range is between 10K and 100K.In the low temperature environment, gases form into ice on the grains. The interstellar ice is composed primarily of H2O、NH3、CH3OH、CH4、CO and CO2, etc. The complex organic compounds can be created in the ice via irradiation process. We use 15keV H3+ bombard CO- or CH- compounds with H2O and D2O ice mixtures. After H3+ bombard CO- or CH- compounds with

By Changing length of mask and etching time, we successfully fabricate sawtooth grating. During the experiment we also found that the residue after RIE process can be used as wet etching mask which was a kind of Carbon-Fluorine polymer, and th
