The interaction of infra-red laser radiation with solid targets
The pulsed HF chemical laser was discovered in 1966 by Deutsch. Early lasers had very low power outputs; it is only more recently that high power pulsed HF/DF lasers have emerged. This thesis is concerned with the development of a 10J HF laser in 1976 and subsequent interaction experiments. The …

Membrane investigations using infra-red spectroscopy and multivariate target factor analysis
Mid Infrared spectroscopy coupled with multivariate Target Factor Analysis (TFA) was used to investigate permeation and localisation of drugs through and within synthetic membranes and human skin. Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy was used for the …

Infra-red studies of carbon monoxide and hydrogen absorbed on silica supported metal catalysts
… cobalt, and iron catalysts was studied using infrared spectroscopy. The products occurring in the gas phase, as well as spectra of adsorbed CO surface species in the frequency range 2300 - 1700 cm−¹ for different order of addition of the two reactants was examined. Bulk powdered samples and …

Studies of the structure and water absorption properties of cellulosic materials by infra-red spectroscopy
… of viscose, dicel and tricel films, prepared in a pure form by techniques develope d during the course of this work. These three materials provide a means of following how progressive acetylation (from 0% in viscose to 88.3% in dicel to 98.3%'in tricel) influences structure and water …

Static and dynamic analysis of near infra-red dorsal hand vein images for biometric applications
… out on static and dynamic analysis of near infra-red dorsal hand vein images for biometric applications. It focuses on the investigation of the classification of old and young groups of people, and analyses vital signs underlying dorsal hand vein images. All research is based on the database …

TOWARDS A GENERALIZATION OF THE NESTED SOFT-COLLINEAR SUBTRACTION SCHEME FOR NNLO INFRA-RED DIVERGENCES IN QCD
… while searching for new physics. Theoretical predictions for these processes rely on quantum field theories, most importantly perturbative Quantum Chromodynamics (pQCD). Consequently, the development of theoretical techniques capable of providing predictions at progressively higher orders of …

Further development of a non-invasive infra-red (IR) system in clinical assessment of knee laxity in healthy volunteers
… Implementing these tools into an altered laxity assessment, two measurements of varus and valgus laxity, and AP translation were taken at 5°, 15°, 30° & 45° intervals. Valgus measurements were repeatable (CR 3°) between 5° and 15° of flexion, varus measurements were repeatable at 5°. …

The investigation of an inexpensive infra-red camera based building monitoring system for the aid of efficient building development
… project. Firstly as statistical validation occurred through four tests whereby the thermal camera was validated with a mercury thermometer for temperature measurement. The second experiment was focused on the capability of the thermal camera to detect anomalies in a structure. This experiment …

Structural Investigations of Nematode Anhydrobiotic and Rab11-FIP Proteins by Far-UV Circular Dichroism and Mid-IR Fourier Transform Infra-Red Spectroscopy
… AavLEA1 nematode protein was discovered to be a natively unfolded protein with an extended tertiary conformation. From FTIR melt experiments this protein was shown to resist temperature-induced aggregation and to act synergistically with the trehalose disaccharide in retarding the …

Sonogashira coupling reactions in the synthesis of near infra-red emitters and of star systems for the study of charge propagation in dendrimers
"Sonogashira coupling reactions have been used for the synthesis of three functional systems: arylethynyl-substituted 9,10-anthraquinones, Os(II) bis(2,2'-bipyridine) (3,8-diarylethynyl-1,10-phenanthroline) complexes and four star-shaped molecules incorporating the 4-benzoyl-N-alkylpyridinium …

Quantitative non-destructive study of sub-micron defects in very large scale integrated-circuit silicon using transmitted and reflected infra-red laser scattering
"The limits and capabilities of the Scanning Infra-Red Microscope (SIRM) and the Optical Precipitate Profiler (OPP) to detect oxygen precipitate defects in silicon were investigated. Two sets of specimens were made and studied. One set had wafers containing the same bulk defect density, but had …
