Near Infra-Red Absorption Tomography for Measurement of Chemical Species Distribution
نویسندگان
چکیده
The spatial distribution of chemical species can be a critical determinant of the performance of chemical reactors. One such reactor is the combustion chamber of the Internal Combustion engine. This paper presents a design for the measurement of hydrocarbon concentration distribution within a running engine using Near Infra-Red absorption tomography. The fundamentals of the technique, and design parameters for the equipment are discussed. By utilising micro-optic components, a minimally invasive system is feasible and by utilising advanced laser/photodetector combinations, good temporal performance is anticipated.

Infra-red Absorption Spectra of Steroids
In this paper, the infra-red absorption spectra of a number of crystalline natural estrogens are presented and considered in relation to chemical structure. As a group, the natural estrogens are distinguished chemically from other steroids by the benzenoid structure of Ring A, which gives rise to certain infra-red absorption bands by which their spectra may be differentiated from those of other...

Incorporation of copper species into silica matrix was performed by the sol-gel method. Copper ions and copper particles were doped using two different copper sources; Cu(NO3)2.3H2O and copper particles chemically synthesized.The particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. On the other han...

Hyphenating High Temperature High Performance Liquid Chromatography (HT-HPLC) with High Temperature Size Exclusion Chromatography (HT-SEC) (High Temperature Two Dimensional Liquid Chromatography (HT-HPLC x HT-SEC or HT 2D-LC)) leads to an isocratic elution in the second dimension, which in turn enables to use IR detector (quantitative detection) for monitoring the eluting polymers. Experimental...

Optical diffusion tomography (ODT) has recently found renewed interest by the scientific and medical community due to advances in imaging electronics, computer processing power, development of tumor marking dyes, and image reconstruction algorithms. The development of this technology may allow the use of near infra red and infra red light to image internal structures of tissue without the use o...
متن کاملPlasma-electrolysis synthesis of TiO2 nano/microspheres with optical absorption extended into the infra-red region.
A novel plasma-electrolysis method is introduced to synthesize high-quality TiO(2) nano/microspheres that exhibited excellent optical absorption covering the range from ultraviolet to infra-red. Both experimental and theoretical results show that the oxygen vacancies in the TiO(2) spheres are primarily responsible for this wide absorption.
