The theory behind FTIR analysis given here is general but the application examples only relevant for a combustion situation like boilers, furnaces, incinerators fires and for automobile exhaust measurements. Typical for these applications are the presence of large quantities of water and carbon dioxide and sometimes hydrocarbons which makes the measurement and evaluation procedure somewhat.
FTIR spectroscopy during cure demonstrated that the reaction kinetics in these systems differ from those previously reported for similar systems. Over moderate to high copolymer concentration the systems behaved as expected of a block copolymer in a solvent selective for one block. As concentration increased, transitions from BCC-Hex-Gyr-Lam phases were observed by SAXS. At lower.

Ag(I)-containing hydrogels formed by reactions with 6-thioguanine, 6-mercaptopurine, and 2-thiocytosine were prepared and characterised by AFM, TEM, XPS, X-Ray, FTIR, UV-Vis, and fluorescent spectroscopy. Au(I) 2-thiocytosine was also prepared, but this produced a discrete complex rather than a gel. AFM of the Ag(I) xerogels showed the.
CHAPTER 2 CHARACTERIZATION TECHNIQUES 2.1 INTRODUCTION The background, motivation and the current status of the present research work have been discussed in the chapter 1. This chapter presents an overview of the various principle and instrumentation techniques such as, X - ray diffraction technique, Fourier transform infrared spectroscopy (FTIR), X - ray photoelectron spectra (XPS), Field.
The research reported in this thesis is focused on the identification of the structure of point defects in diamond using a variety of spectroscopic techniques. The defects studied are introduced by doping during synthesis, irradiation damage and annealing. Diamond produced by high-pressure high-temperature (HPHT) synthesis and chemical vapour deposition (CVD) are studied.
Rapid prototyping techniques (RP) hold great promise for designing 3-dimensional (3-D) regular and ordered scaffolds for tissue engineering applications. With these techniques, good architecture reproducibility as well as porosity control of the structure can be obtained. This work dealt with the fabrication of tissue engineering scaffolds with regular micrometric geometry by using an in-house.
This thesis has investigated the geological origin of diamonds from the Ural Mountains. A set of inclusion-bearing diamonds from alluvial deposits in the western part of the Urals was characterised on the basis of their morphological features, nitrogen contents and nitrogen aggregation states, carbon and nitrogen stable isotopes, mineral inclusion geochemistry and radiometric isotopic ages of.
This thesis demonstrates the feasibility of accelerating phytoplankton phenomics using Fourier Transform Infrared (FTIR) microspectroscopy, a powerful yet under-utilised frontier technology. The extensive phenotypic variation shown by Southern Ocean phytoplankton provided excellent scope for demonstrating the power of the microspectroscopic.
