In surface-enhanced Raman scattering (SERS), both chemical (CE) and electromagnetic (EM) field effects contribute to its overall enhancement. However, neither the quantification of their relative contributions nor the substrate dependence of the chemical effect have been well established. Moreover, there is to date no understanding of a possible coupling between both effects. Here we demonstrate how systematically engineered silver and gold planar and nanostructured substrates, covering a wide range of field enhancements, provide a way to determine relative contributions of chemical and electromagnetic field-enhancement in SERS measurements of benzenethiol. We find a chemical enhancement of 2 to 14 for different vibrational resonances when referencing against a vibrational mode that undergoes minimal CE. The values are independent of substrate type and independent of the enhancement of the electromagnetic intensity in the range from 1 to 106. This absence of correlation between chemical and electromagnetic enhancement resolves several long-standing controversies on substrate and intensity dependence of the chemical enhancement and allows for a more systematic design of SERS substrates with desired properties.

Theoretical approaches can provide insight into the mechanisms and magnitudes of electromagnetic and chemical effects in surface-enhanced Raman scattering (SERS), properties that are not readily available experimentally. Here, we model the SERS spectra of two geometries of the prototypical Ag20–pyridine cluster using a semiempirical INDO/SCI approach that allows a straightforward decomposition of the enhancement factors at each wavelength into electromagnetic and chemical terms, with proper treatment of resonant charge-transfer contributions to the enhancement. The method also enables us to determine the dependence of the enhancement on the electrochemical potential. We show that the electromagnetic enhancements for the Ag20 cluster are <10 far from resonance but can increase to 102 to 103 on resonance with plasmon excitation in the cluster. The decomposition also shows that for the systems studied here, the chemical enhancements are primarily due to resonance with excited states with significant charge-transfer character. This term is typically <10 but can be >102 at electrochemical potentials where the charge-transfer excited states are resonant with the incoming light, leading to total enhancements of >104.

The underlying theme of this thesis is one of exploring the processes involved in the enhancement of percutaneous absorption. The development of an attenuated total reflectance Fourier-Transform infrared (ATR-FTIR) spectroscopic method to analyse diffusion of suitable topically applied compounds in membrane is described. Diffusion coefficients (D/h2) and membrane solubility (AO) for topically applied compounds were determined using a solution to Fick's second law of diffusion. This method was employed to determine the diffusional characteristics of a model permeant, 4-cyanophenol (CP), across silicone membrane as a function of formulation applied and permeant physicochemical properties. The formulations applied were able to either affect CP diffusivity and/or its membrane solubility in the membrane; such parameters partially correlated with permeant physicochemical properties in each formulation. The interplay during the diffusion process between drug, enhancer and vehicle in stratum corneum (SC) was examined. When enhancers were added to the applied formulations, CP diffusivity and solubility were significantly enhanced when compared to the neat propylene glycol (PG) application. Enhancers did not affect PG diffusivity in SC but enhancers did affect PG solubility in SC. PG diffusion closely resembled that of CP, implying that the respective transport processes were inter-related. Additionally, a synergistic effect, which increases CP diffusivity and membrane solubility in SC, was found to occur between PG and water. Using 12-azidooleic acid (AOA) as an IR active probe for oleic acid, the simultaneous penetration of CP, AOA and PG into human stratum corneum was determined. It was found that the diffusion profiles for all three permeants were similar. This indicated that the diffusion of each species through SC was closely related and most likely occurred via the same route or SC microenvironment.

In this thesis, mass diffusion processes in nanofluids are investigated by means of total internal reflection fluorescence (TIRF) microscopy and physical modeling. In particular, the design of a novel TIRF microscopy system and image processing algorithms specifically aimed at the measurement of the mass diffusion coefficient of a fluorescent dye in nanofluids are presented.When studying the diffusion of rhodamine 6G (R6G) in deionized water with this TIRF microscopy system, it is found that the mass diffusion coefficient averages to D = 3.3E-10 square meter per second. Both the accuracy and precision of this measurement compare to the best reported values.Numerical simulations are performed to quantify the detrimental effect of solutal buoyancy on mass diffusivity measurements in a confined millichannel geometry. It is shown that the buoyancy-induced fluid motion significantly affects the measurements even at low dye loadings, but that injecting the dyed fluid through a porous hydrophilic membrane hinders the onset of natural convection.The TIRF microscopy method is then applied to the measurement of the mass diffusivity of R6G in water-based alumina nanofluids of various volume fractions (0.1 to 4.0 vol%). A mass diffusion enhancement up to 10-fold is observed in a 2 vol% nanofluid when compared to deionized water.Following this observation, a Brownian motion-induced dispersion model is developed to explain the enhancement of mass diffusion. It appears that the nanoparticle Brownian motion is sufficient to induce velocity disturbances in the surrounding fluid. These velocity disturbances are similar to the velocity profile predicted by the Brinkman equations, which allow to draw an analogy between dispersion in diluted fixed beds and dispersion in nanofluids. It is shown that this model is capable of predicting the order of magnitude of the mass diffusivity enhancement in water-based alumina nanofluids.
La diffusion massique dans les nanofluides est étudiée par l'entremise de la microscopie en fluorescence par réflexion totale interne (ci-après nommée microscopie TIRF, pour Total Internal Reflection Fluorescence) et de modélisation physique. En particulier, le design d'un microscope TIRF ainsi que les algorithmes de traitement d'images spécifiquement destinés à la mesure du coefficient de diffusion d'un colorant fluorescent dans les nanofluides sont présentés.La microscopie TIRF et les algorithmes de traitement d'images sont d'abord employés pour déterminer le coefficient de diffusion de la rhodamine 6G (R6G) dans l'eau déminéralisée. Le coefficient moyen obtenu, à savoir D = 3,3E-10 mètre carré par seconde, confirme à la fois la justesse et la précision de la méthode de mesure proposée, comparativement aux techniques établies.L'emploi d'une membrane poreuse hydrophile lors de l'injection de la solution de R6G permet de retarder l'apparition et de réduire les conséquences des effets de la flottabilité solutale sur les mesures de diffusivité dans un canal aux dimensions millimétriques.Ensuite, cette méthode de microscopie TIRF est utilisée pour mesurer le coefficient de diffusion de la R6G dans des suspensions de nanoparticules d'alumine dans l'eau, pour différentes fractions volumiques (0,1 à 4,0%). Les résultats montrent que la diffusion massique est améliorée par un facteur 10 pour un nanofluide contenant 2 vol% de nanoparticules, comparativement à la valeur obtenue dans l'eau déminéralisée.Enfin, un modèle de dispersion induite par mouvement brownien est développé pour expliquer l'amélioration de la diffusion massique. Il s'avère que le mouvement brownien des nanoparticules est suffisant pour induire une perturbation dans le fluide environnant et ainsi créer un profil de vitesse qui sera à l'origine de la dispersion. Ce profil de vitesse s'apparente à la solution aux équations de Brinkman et permet de tirer une analogie entre les nanofluides et les lits de particules fixes pour établir le modèle de dispersion. Les prédictions du modèle concordent avec l'ordre de grandeur du coefficient de diffusion mesuré.

The objective of this work was to modify the surface of polyethersulfone membranes in order to render them more useful in pervaporation for the removal of volatile organic compounds (VOC) from aqueous solutions. Surface Modifying Macromolecules (SMNs) were designed and developed as surface modifiers of asymmetric polyethersulfone (PES) membranes. Eight SMM polymers were synthesized in triplicate using methylene bis-p-phenyl diisocyanate (MDI), polypropylene oxide (PPO) and polyfluoroalcohol (BA-L). They represented a 2$\sp3$ factorial design used to study the effects of reactant stoichiometry, prepolymer reactant concentration and chain length of the polyfluoroalcohol on the SMM properties and reproducibility of the SMM synthesis. The bulk SMM polymers were characterized with differential scanning calorimetry (DSC), gel permeation chromatography (GPC) and elemental analysis. The compatibility between PES and SMM polymers was studied by DSC. The average molecular weight of SMM polymers, determined by GPC, were in the range of $1.0\times10\sp4\rm\ to\ 3.5\times10\sp4$. As predicted by theoretical considerations, SMMs were found to have migrated to the PES surface, rendering it more hydrophobic. This migration effect was confirmed by water droplet contact angle measurements and X-ray photoelectric spectroscopy (XPS). Opaqueness of PES/SMM films and results of DSC showed that SMM was either immiscible or partially miscible with PES. Preliminary pervaporation studies indicated that the addition of SMMs improved the selectivity of PES membranes, used in the separation of chloroform/water mixtures by 150 to 240%, depending on the chemical formulation of the SMM. In several cases, SMMs also improved the permeation rate. From a preliminary assessment of the changes in membrane surface and bulk characteristics, the surface chemistry and energetics were observed to contribute an important role in inducing the membranes' enhanced properties.

The effect of turbulence enhancement at the nozzle exit on fluid flow and heat transfer characteristics was investigated for confined jets from sharp-edged nozzles.
Average turbulence intensity of the jet flow was characterised by integrating the local turbulence intensity values over the width of the nozzle and at several axial positions from the nozzle exit to the near approach to the impingement surface. Average impingement heat transfer was obtained by integrating the local Nusselt number over an area of the impingement surface relevant to the process engineering application of impingement drying of paper.
Of the several simple methods of turbulence generation examined, the most effective was the simple expedient of placing a bar with a diameter 1/8 that of the nozzle width along the centreline of the slot nozzle. For a heat transfer averaging area equivalent to a nozzle area of 5% of the impingement surface and a nozzle to impingement surface spacing of 1.0 to 1.5 times the nozzle width, this simple method increased average heat transfer rates over those of the plain nozzle by 14%, with only a 7% increase in nozzle operating pressure. The results are presented as enhancement in average heat transfer as a graphical function of mean turbulence intensity, and as an empirical correlation between mean Nusselt number, mean intensity of turbulence and Reynolds number.

Transdermal drug delivery is an effective alternative to conventional oral and injectable drug delivery routes. It offers painless and convenient once daily or even once weekly dosing for a variety of clinical indications. The major limitation to successful transdermal drug delivery is the efficient barrier properties of the skin. Significant research efforts have been focused on developing strategies to overcome these barrier properties. These strategies include the use of physical and chemical penetration enhancers. Physical skin penetration enhancers use an external energy source to alter the barrier properties of the skin. The current research focuses on some of these physical skin penetration enhancers on a range of drug molecules and peptides.The first technology investigated was Dermaportation that utilised pulsed electromagnetic energy. This technology enhanced the epidermal permeation of naltrexone in vitro as compared to passive diffusion. A 5-fold increase in naltrexone permeation was observed during Dermaportation application when compared to passive administration. Multiphoton tomography-fluorescence life-time imaging microscopy (MPT-FLIM) analysis of the permeation of gold nanoparticles in the presence of Dermaportation revealed increased penetration across ex vivo human skin. These results demonstrated that the channels created by dermaportation must be larger than the 10 nm diameter of the applied nanoparticles.The second technology investigated was an unpowered magnetic film array technology (ETP), which utilised unpowered magnetic energy. Chapter 3 presents enhanced epidermal permeation of urea with ETP. A 4-fold increase in urea penetration was observed across human epidermis in the in vitro permeation study. Optical resonance tomography was used to visualise the changes in epidermal thickness due to urea permeation as an indication of increased hydration. The results revealed an increase in epidermal thickness at 30 min, to 16% for ETP induced urea permeation as compared to 3% with urea from occlusion. These results further substantiated our previous findings that magnetic energy creates hydrophilic diffusion channels or pores in the skin.The third technology investigated was low-frequency sonophoresis that utilises cavitation bubbles as a force to create channels for drug delivery in the skin. Chapter 4 presents enhanced human skin permeation of 5-aminolevuleninic acid in vitro and curcumin dye in vivo with low-frequency sonophoresis. Two different sources of ultrasound devices that generated low-frequency sonophoresis were investigated. MPT-FLIM analysis was utilised to investigate the effects of sonophoresis on human skin in vivo. This revealed that there was substantial disturbance in the epidermal cells due to cavitation by sonophoresis. Permeation of curcumin was found in the deeper layers of the epidermal membrane with 55 kHz sonophoresis and was confined to the more superficial layers of skin with 21 kHz sonophoresis. Permeation of 5-aminolevuleninic acid across human skin increased significantly when compared to passive permeation.The fourth technology investigated in this research was iontophoresis which utilises a small electric current to drive charged and uncharged molecules across the skin. Chapter 5 presents enhanced epidermal permeation of a range of model therapeutic and cosmetic peptides. Various key parameters such as pH, concentration and presence of counterions and co-ions that are essential for effective iontophoretic delivery of these peptides were investigated. The iontophoretic delivery of 5- aminolevulenic acid revealed a 15-fold enhancement when compared to passive diffusion. For dipeptide (Ala-Trp) the mean cumulative amount increased iontophoretic delivery from 0.4±0.4, 0.1μg/cm2 to 16.0±8.8, 3.6μg/cm2 (Mean±SD, SEM) was observed when the donor pH was reduced from 7.4 to 5.5. The corresponding current intensity (0.38mA/cm2) normalised flux was 36.1±19.5, 11.2μg/(mA.h) for iontophoretic Ala-Trp. For the tetrapeptide (Ala-Ala-Pro-Val) the mean cumulative amount that permeation with 2h iontophoresis was 350.4±45.9, 15.3μg/cm2 (Mean±SD, SEM) compared to zero passive permeation. A 4-fold increase in acetyl hexapeptide-3 delivery occurred with iontophoresis compared with passive application. In addition it was observed that lowering of donor solution pH and the presence of counterions and co-ions reduced the iontophoretic delivery of acetylhexapeptide-3. Iontophoresis provided a significant enhancement factor for the decapeptide, triptorelin acetate with a 16-fold increase in epidermal permeation compared with passive permeation. The iontophoretic permeation was concentration dependent with mean cumulative amounts of 48±28, 14 μg/cm2 (Mean±SD, SEM) achieved with 9 mM concentration of triptorelin acetate.Overall the technologies investigated in this research work presented enhanced permeation of drug molecules and peptides. In addition MPT-FLIM was demonstrated to be an efficient visualisation tool for permeation within the skin. This research demonstrates the effectiveness of physical skin permeation enhancement techniques and extends our understanding of these technologies.

Heat transfer characteristics under a single turbulent confined slot jet were determined experimentally. New enhancement techniques for the impingement heat transfer rate are proposed and tested experimentally. The results from each enhancement technique are compared with those for a smooth slot nozzle configuration with the same apparatus.
The impingement heat transfer rate was observed to increase due to internal finning of the slot nozzles. Both rectangular and triangular fins were tested. The fins acted as roughness elements. Experimental results with the "rough" nozzle show that the stagnation and average heat transfer rates can be enhanced by up to 15% and 10%, respectively. However, an increase in pressure drop across the nozzles is also noted.
Use of inclined confinement surfaces of 10° and 20° angles accelerate the exit flow provides average impingement heat transfer rates comparable with those for parallel wall confinement. Experimental results show no significant change in the heat transfer distribution for the inclination angle of 10°, while the average heat transfer coefficient is in fact decreased slightly for the inclination angle of 20° at high jet Reynolds numbers.
It was found that insertion of a single turbulence generator in the jet flow provides superior impingement heat transfer without any increase in the system pressure drop. Two types of turbulence generators (square rod and thin plate) were investigated. Both turbulence generators provide the same level of average heat transfer enhancement (up to 15%).
