Le confinement des antibiotiques dans des matrices inorganiques, constituent une classe de matériaux particulièrement bien adaptée, pour la conservation de leurs activités. Cette thèse à pour objectifs: (1) d’établir une corrélation entre la localisation des antibiotiques dans les matrices HDL et leur activité antibactérienne, (2) de définir la matrice la plus adéquate pour protéger les antibiotiques de la dégradation thermique et/ou photonique. Nous nous sommes intéressés à étudier l’influence de la localisation de l’antibiotique dans le matériau sur son activité antibactérienne, et de vérifier si la phase HDL peuvent protéger les antibiotiques de la dégradation thermique et/ou photonique.Dans ces travaux, nous avons utilisé des hydroxydes doubles lamellaires (HDL) de type Zn2Al, Mg2Al, Ni2Al et Mn2Al comme des supports pour différentes types d’antibiotiques (cycline, polypeptide et enzymatique). Nous avons étudié l’immobilisation de deux antibiotiques de types cyclines tetracycline (TCH) et oxytetracycline (OXY), par deux méthodes (la coprécipitation et l’échange anionique). Nous avons étudié l’impact de l’irradiation du UV ou/et stockage à différentes températures (30, 60 et 120°C) pour évaluer leurs activités antibactériennes. Les résultats ont montré que les antibiotiques sont localisés à la surface des grains de la phase HDL. Les matériaux préparés par coprécipatation présentent un taux de relargage et une activité antibactérienne plus importante que celles préparé par échange anionique. Une baisse significative de l’activité antibactérienne après un stockage à haute température et l’exposition à la lumière UV est observée. Cela permet de conclure que la phase HDL accélère la dégradation des antibiotiques sous l’effet du température et la lumière UV. Nous avons étudié l’immobilisation de la nisine dans des différentes phases HDL, en tenant compte de l’effet du rapport molaire, l’effet de matrice, l’effet de l’anion et l’effet de morphologie. Les résultats ont montré que l’immobilisation de la nisine dans les différentes phases HDL n’affecte pas son activité antibactérienne à 4°C. En revanche, on remarque que l’activité de la nisine est moins sensible à la température quand elle est confinée.. La localisation de la nisine joue donc un rôle très important dans la meilleure protection de l’activité antibactérienne. Enfin nous avons effectué l’immobilisation du lysozyme dans les différentes phases HDL. Nos résultats ont montré que, le lysozyme est localisé à la surface des grains du matériau, on note un abattement plus important pour le lys libre que lYS adsorbé. Cela peut être du à une dénaturation du site enzymatique.

The confinement of antibiotics in inorganic matrices results in a class of materials particularly suitable for the conservation of their activities. This thesis aims to: (1) establish a correlation between the localization of antibiotics in HDL matrices and their antibacterial activity, (2) define the most appropriate matrix to prevent the antibiotics thermal and / or photon degradation. We were…

Les travaux présentés dans ce manuscrit sont consacrés à l’étude de la spectroscopie FTIR à très haute résolution de la molécule de tétrafluorométhane CF4 en vue d’applications atmosphériques. Une très bonne modélisation de son spectre d’absorption est donc essentielle pour les mesures de concentration atmosphérique. Cette thèse a été effectuée dans le cadre du Groupe de Spectrométrie Moléculaire et Atmosphérique (GSMA) de l’Université de Reims Champagne Ardenne et au sein du Laboratoire de Spectroscopie et Dynamique Moléculaire (LSDM) de l’École Nationale Supérieure d’Ingénieurs de Tunis.Ce manuscrit est structuré en cinq parties. La première partie de ce travail de thèse concerne les généralités et les propriétés physiques spectroscopiques de CF4. La deuxième partie décrit les conditions expérimentales des différents spectres enregistrés soit à Reims ou à la ligne AILES du synchrotron SOLEIL. La troisième partie expose l’aspect théorique de la spectroscopie qui porte sur le formalisme tensoriel, Hamiltonien et moment dipolaire effectifs que nous avons utilisés pour calculer et traiter nos spectres. La quatrième partie offre une description des logiciels utilisés lors des analyses : MIRS et SpectrAssign. Finalement, dans la cinquième partie, nous présentons les résultats de l’analyse et nous les interprétons en donnant des comparaisons entre les spectres observés et calculés.

The work presented in this manuscript is devoted to the study of very high resolution FTIR spectroscopy of the molecule of tetrafluoromethane CF4 for atmospheric applications. Therefore, a very good modeling of its absorption spectrum is essential for atmospheric concentration measurements. This thesis was carried out in the Molecular and Atmospheric Spectroscopy Group GSMA of the university of Reims Champagne-Ardenne and within the Laboratory of Spectroscopy and Molecular Dynamics LSDM of the University of Tunis.This manuscript is structured into five main parts. The first part of this thesis concerns the generality and the spectroscopic properties of the CF4. The second part describes the experimental conditions of the different spectra recorded either in Reims or at the AILES line of the SOLEIL synchrotron. The third part presents the theoretical aspect of spectroscopy which deals with the tensorial formalism, effective Hamiltonian and dipole moment that we used to calculate and process our spectra. The fourth part provides a description of the software used during analyzes: MIRS and SpectrAssign. Finally, in the fifth part, we present the results of the analysis and we interpret them by giving comparisons between the observed and calculated spectra.

▼

The possible role of Electron Donor Acceptor complexes or interactions in controlling and modifying the electron or charge flow, as a bridge between molecular components in biological systems is a fascinating area of research. In almost all such studies with quinones as acceptors the model compound has been Chloranil, which is tetrachloro-1,4 benzoquinone. This is too strong an acceptor and insoluble in water. But systems in vivo are often reversible and involve aqueous and ionising media. newline newlineIn the first part of the investigation 2,5 dichloro, 3-6-dimethoxy p-benzoquinone CMBQ is the quinone chosen. For study with its accepting capacity moderated by two, methoxy groups in place of chlorines. It is soluble in water. Its complexing ability has been studied first in carbon tetrachloride with the aromatic hydrocarbons hexamethylbenzene, fluorene, naphthalene, durene and acenapthene. The interaction is found to be very weak even with the fairly strong donor HMB. With all the other donors contact pair interaction seems to prevail and intensity borrowing from the donor excited state appears to contribute to the increased absorption in the spectra. Even carbontetrachloride is shown to compete with this quinine as an acceptor and this has been dramatically demonstrated in the specific solvent effect that has, brought forth some special features in the results. newline newlineIn spite of this moderation in its electron accepting ability this quinone is found to have strong interaction with aliphatic amines which act as n-donors. This aspect forms the subject of study itr the second part of this dissertation. N-butylamine and other amines aire found to, interact with CMBQ in water solution giving rise to changes in .the absorption spectra with time. Beyond the stage of outer complex formation, an ionic complex leads on further to a nucleophilic substitution reaction showing up a 3,6-diamino substituted product. The kinetics has been investigated.

▼ Carbon monoxide (CO) is a toxic byproduct of incomplete combustion in hydrocarbon-fueled systems which poses many environmental and human health hazards. Not only is CO hazardous, it also correlates to combustion efficiency. A mid-infrared (IR) CO detector has been developed to monitor the amount of CO produced by a high-pressure test rig developed by Parametric Solutions, Inc. under contract from Toshiba. The combustor rig was designed to operate using the Allam cycle, which requires methane and an oxygen/carbon dioxide blend, and operates at approximately 30MPa and 1150°C. The mid-IR system operates at the fundamental absorption band, v”=0, R(12), of CO near 4.5 μm. The mid-IR diagnostic was constructed from a tunable quantum cascade laser produced by Alpes Lasers, an absorption cell with two window ports for monitoring CO exhaust concentration, and two IR photodetectors. Temperature and pressure sensors were mounted near the absorption cell to monitor exhaust flow conditions, and the operational wavelength of the laser was determined by a calibration process using a known mixture of CO and N2. Environmental conditions at the test facility posed significant difficulties in the data acquisition process for the IR diagnostic. Fluctuating environmental temperatures proved to be problematic when operating cryogenic photodetectors and stabilizing a quantum cascade laser designed to operate with an internal temperature of -15°C. Improvements to the IR system included elimination of problematic stagnation regions via a new absorption cell design, and an increase in the CO detection limit. During steady state conditions, the mid-IR diagnostic measured the CO concentration to be about 539.5 ± 80.6 ppm. It was discovered that during some of test runs, the CO absorption trace would be artificially raised due to unknown deposits on the inside of the cell windows. The IR diagnostic was shown to have superior CO detection response time and the ability to resolve features not detected by other CO detector counterparts.

▼ In recent years, the demand for air conditioning systems due to the demand of higher comfort conditions has led to a significant increase for primary energy resources such as solar energy for cooling. Solar cooling (SC) is getting more and more readily available and cost effective. SC is environmentally friendly and decreases ???CO???₂ emissions thus reducing the greenhouse effect. Currently, one of the most frequently used solar cooling systems is the water absorption chillers. Most traditional air conditioning systems use compression technology for their chillers. The absorption chillers used for SC usually combine with flat plate or an evacuated tube collectors. These types of SC are relatively young and are still being developed. In this paper, a two story building that has an area of 2796 square meters and a max cooling load of about 211 kWh (60 RTh) is analyzed. Case Study 1 uses three of these buildings, Case Study 2 uses six buildings, and Case Study 3 uses 8 buildings. Given the different case studies, different chillers were chosen and the number of evacuated tube collectors and storage tanks are either increased or decreased given the number of buildings. The building???s design and cooling loads were developed with conjunction with the ASHRAE Example Building for Chapter 30, Nonresidential Cooling and Heating Load Calculations, of the 2005 ASHRAE Handbook-Fundamentals [1]. For the cooling and heating load calculations the radiant time series (RTS) method was used. From the cooling loads, the collector area and the volume of the storage tank were determined. In each of these three case studies, a cost analysis was made to compare the solar absorption system versus the tradition compression chiller. This analysis is made to see if this relatively new type of SC is even feasible in the Sacramento area. Only in Case Study 1, the solar absorption system (796,663) is more economical than the vapor compression system (901,624) after 20 years. The cost of Case Study 2 is 1,703,456 for the solar absorption system and 1,681,408 for the vapor compression system after 20 years. Finally, for Case Study 3, which included 8 buildings, the solar absorption system cost is 2,240,643 and the cost for vapor compression system is 2,194,774 after 20 years.

▼ Intravascular volume is maintained by complex interplay between organ systems with a main role for renal sodium, and water handling. The glomerulus filters a large quantity of water and salt daily with the majority of sodium, water and calcium being reabsorbed from the proximal tubule (PT). The renal reabsorption of sodium, water and calcium are interconnected. Apical influx of sodium from the PT occurs via NHE3 in exchange for a cytosolic proton. Cytosolic sodium is excreted back into the blood via either sodium potassium ATPase or a sodium dependent bicarbonate transporter. The rate-limiting step for NHE3 activity is the presence of a cytosolic proton. This is generated by cytosolic carbonic anhydrase II (CAII), an enzyme mediating the catalysis of CO2 and H2O to form HCO3- and H+. CO2 and H2O enter the PT epithelial cell through the water channel aquaporin-1 (AQP1). Osmotically driven water flux across the PT also drives calcium reabsorption from this segment, a process linked by NHE3. CAII interacts with many membrane transporters including NHE1, AE1, MCT1 and NBCe1. We identified potential CAII binding sites in both NHE3 and AQP1. A primary hypothesis of this thesis is that CAII physically and functionally interacts with both NHE3 and AQP1. CAII and NHE3 were closely associated in a renal proximal tubular cell culture model as revealed by a proximity ligation assay. Direct physical interaction was confirmed in solid-phase binding assays with immobilized CAII and C-terminal NHE3 glutathione-S-transferase fusion constructs. To assess the effect of CAII on NHE3 function, we expressed NHE3 in a proximal tubule cell line and measured NHE3 activity. NHE3-expressing cells had a significantly greater rate of intracellular pH recovery than controls. Inhibition of endogenous CAII activity with acetazolamide significantly decreased NHE3 activity, indicating that CAII activates NHE3. To ascertain whether CAII binding per se activates NHE3, we expressed NHE3 with wild-type CAII, a catalytically inactive CAII mutant (CAII-V143Y), or a mutant unable to bind other transporters (CAII-HEX). NHE3 activity increased upon wild-type CAII coexpression, but not in the presence of the CAII-V143Y or HEX mutant. These studies support an association between CAII and NHE3 that increases the transporter's activity. CAII colocalizes with AQP1 in the renal proximal tubule. Expression of AQP1 with CAII increased water flux relative to AQP1 expression alone. Expression of catalytically inactive CAII failed to increase water flux through AQP1. Proximity ligation assays revealed close association of CAII and AQP1, an effect requiring an acidic cluster of amino acids in the cytosolic tail of AQP1. This motif was also necessary for CAII to increase AQP1-mediated water flux. Red blood cell ghosts resealed with CAII demonstrated increased osmotic water permeability compared with ghosts resealed with albumin. Renal cortical membrane vesicles isolated from CAII-deficient mice has reduced water flux, which is measured by stopped-flow light scattering.…

▼ An experimental and numerical study of absorption of ammonia vapor bubbles into a constrained thin film of ammonia-water solution is presented in the context of a potential reduction in size of a heat-actuated heat pump component. A large-aspect-ratio channel with a depth of 600 µm restricts the thickness of the weak solution film, while ammonia vapor bubbles are injected from a porous wall. Experiments are performed at a nominal system pressure of 6.2 bar absolute and at an inlet weak solution temperature of 75ºC. A counter-flowing coolant in a minichannel removes the generated heat of absorption. The mass flow rate of the weak solution, vapor flow rate, coolant inlet temperature, and mass flow rate of the coolant solution are varied. Two absorber channel geometries are considered: 1) a smooth 600 µm channel, and 2) a stepped geometry that has 2-mm deep trenches across the width of one of the channel walls. The 1-D, steady state species and energy transport equations, are solved for the smooth-channel absorber to yield, along the length of the channel, concentration and temperature profiles of the solution stream and the temperature profile of the coolant fluid stream. Experimental results indicate that overall heat transfer coefficients vary from 700 W/m²-K to 2,300 W/m²-K, while the mass transfer conductances range from 0.024 kg/s-m² to 0.24 kg/s-m². The coolant inlet temperature has a significant effect on the mass transfer rates. At the highest inlet coolant temperature of 58ºC, up to 1.5 g/min of vapor is at best absorbed into 35 g/min of weak solution for the smooth absorber plate, while at the lowest coolant temperature of 30ºC, up tp 3 g/min of vapor is absorbed in 35 g/min of weak solution with the same absorber plate. For the stepped absorber geometry, only 1 g/min of vapor is absorbed into 35 g/min of weak solution for the highest coolant temperature of 58ºC, while for the lowest coolant temperature of 30ºC, 5 g/min of vapor is absorbed in 40 g/min of weak solution. Trends of local variation of temperature and convected vapor from the numerical parametric study complement experimental results and provide further insight into the performance of the absorber. Based on the experimental results, a preliminary size estimate for the absorber to operate in a cooling cycle with a 6 kW evaporator load is provided. Other considerations such as strong solution exit subcooling and porous plate pressure drop are also addressed. Advisors/Committee Members: Narayanan, Vinod (advisor), Apte, Sourabh V.

▼ The first part of this study is concerned with setting up a reactive distillation process for production of tert-amyl-methyl ether (TAME). This work was linked to the development of etherification technology of Neste Oy. TAME production makes possible to upgrade some low value olefinic components to high value gasoline. Moreover, it has a significant impact in the reduction of the air pollution caused by the cars by introducing oxygen to the gasoline. However at the time of the study, there was no technology available for production of that component. Reactive distillation (RD) had been applied successfully to the production of the tert-butyl-methyl-ether (MTBE). Thus it seemed worth of trying to apply RD to TAME production as well. The actual work of setting up the process was accomplished using a simulation model of a reactive distillation column. Arrangement of the column and conditions of the experimental runs were determined with the model developed earlier by Aittamaa and Kettunen (1993). The pilot run was successful, so that ethers could be produced as planned and experiments verified with the existence of the operating regimes predicted by the model. The results of this study had a significant impact on the development of the highly successful NExTAME and NExETHERS technologies, even if the final solution was based on the Side Reactor Concept (SRC), i.e. a combination of a distillation column and a reactor connected to the column via side streams, rather than on RD. The second part is the development of a rate-based model of a reactive distillation column including the effects of incomplete lateral mixing on the trays. Most published tests with RD have been performed with small pilot or bench scale columns. In such columns vapour and liquid mixing is nearly complete. However, that is not the case in large industrial columns. On the other hand, making tests with reactive system in columns having diameter of two meter or more is very expensive and practically impossible for most research institutions. Not only the sheer size and utility consumption of such devices are large, but the feed and product volumes are huge even for a short run. With non-reacting systems it is often possible to recycle the products back to the feed, but when reaction takes place, that is much more difficult. If lateral mixing is suspected to have importance in some particular case, a mathematical model is probably the only viable way to estimate its significance before the full-scale plant is built. Two different models for the effects of the lateral concentration profiles on reactive distillation trays were developed. The first model is an eddy diffusion model, the other one is a mixed pool model of reactive distillation trays. The basic principles of both models are known already earlier but both include novel features. Similar models have not been applied earlier to the reactive distillation. The eddy diffusion equations are solved simultaneously and rigorously with the other equations of the equation group describing the… Advisors/Committee Members: Helsinki University of Technology, Department of Chemical Technology, Laboratory of Chemical Engineering and Plant Design.

▼ Glucosamine (GlcN) is an amino monosaccharide that is widely used as a food supplement in the treatment of osteoarthritis (OA). In vitro and animal studies strongly support the therapeutic efficacy of the compound; however, clinical reports and meta-analysis are inconclusive. As compared to the concentration used to assess GlcN efficacy in vitro or in animal models, the maximum plasma concentration of 0.3-2 mg/ml typically seen following the recommended human oral dose of 1500 mg/day is sub-therapeutic. This is mainly due to the low oral bioavailability of GlcN. The objectives of this thesis were to investigate the absorption kinetics of GlcN and to determine the different factors that may contribute in decreasing GlcN gut availability. We were able to improve a simple sensitive HPLC assay of GlcN in human and rat plasma with a lower limit of quantification (LLOQ) of 50 ng/mL. The method was further applied in our study. In the current thesis we revealed that capacity-limited intestinal absorption was not behind the low oral bioavailability of GlcN, as both in vivo and in vitro results demonstrated linear absorption kinetics. GlcN intestinal absorption was found independent of glucose levels and food co-administration. The glucose transporter (GLUT2) is involved in GlcN intestinal absorption; however, passive diffusion may co-exist. Our in vitro studies confirmed that GlcN is absorbed throughout the intestinal tract with the highest permeability from the duodenum. An average of 14.52  6% could not be accounted for in the mass-balance determination after GlcN was incubated with the everted rat segments, indicating that part of the administered dose is either degraded or utilized by the intestinal tissue. Moreover, treating the rats with antibiotics prior to GlcN administration led to a pronounced increase in the compound bioavailability accompanied by a significant increase in the percent of the oral dose excreted unchanged in the rat feces (p < 0.05), from 0.11 ± 0.15% in the control rat to 11.18 ± 4.9% in the antibiotic treated rats. This points to a significant degradation by the intestinal flora that may at least in part explain the low oral bioavailability of GlcN.

▼ X-ray absorption spectroscopy is a diagnostic technique that is able to probe the state of a plasma in detail. Such a measurement usually requires that the plasma under study not radiate in the bandwidth of the probing X-ray flux. This is usually accomplished by limiting the temperature of the sample plasma. The research presented in this thesis extends the temperature range of absorption spectroscopy so that more plasmas may be explored with this diagnostic. This is realized in the design of a novel spectrometer based around the geometry of an ellipse. The design is able to discriminate between probing X-rays and those emitted by a sample plasma, relaxing the temperature restriction. The spectrometer's unique design uses a doubly curved mica crystal for X-ray dispersion. The geometry of the spectrometer is verified by ray tracing calculations assuming Bragg reflection from mica in the second order. Control of other reflection orders is attempted by means of filtering and control of the source spectrum. This is found to be insufficient to control fifth order reflections. Potential solutions are presented to combat these fifth order reflections, but all were considered unlikely to succeed in a timely manner. The broad X-ray spectroscopy expertise gained from the development and implementation of the elliptical design is then used to explore the physics of aluminum's K-edge. This is done using point projection absorption spectroscopy to study a single 25 [MICRO SIGN]m diameter 1199 alloy aluminum wire through which a peak cur- rent of 120 kA is passed. The current heats the aluminum from room temperature to a few electronvolts. The plasma is diagnosed using a spherical quartz crystal spectrograph that records the details of the X-ray spectrum near aluminum's K-edge at 1559 eV. The spectroscopic features of the aluminum plasma are analyzed using a genetic algorithm to match observed spectra to theoretical opacity values. The quality of the fit is discussed by identifying the spectral features that are both present and missing from the opacity calculations. Comparisons are also made to past laser driven studies of the aluminum K-edge. A hypothesis to explain the missing features is proposed. Advisors/Committee Members: Hammer,David A.

▼ The conventional CO2 absorption process, using an aqueous 30 wt% monoethanolamine (MEA) solvent for postcombustion CO2 capture, is energy intensive and thus costly. The novel phase transitional CO2 absorption process has been regarded as a promising alternative to the benchmark MEA process. The solvent in a phase transitional process turns into two phases after CO2 absorption; one phase contains the majority of the absorbed CO2 while the other is CO2 lean. This key feature of a phase transitional process enables the use of only the CO2 rich phase for CO2 stripping and solvent regeneration, which can reduce the energy requirement compared with the MEA process. We investigated two scenarios of phase transitional processes (i.e., liquid-solid and liquid-liquid) to overcome the energy disadvantages associated with the MEA process. For the liquid-solid CO2 absorption process, an aqueous solution of potassium carbonate was applied and the CO2 absorption product, i.e., potassium bicarbonate (KHCO3), was subjected to a crystallization process due to its limited aqueous solubility at low temperatures (<40℃). The KHCO3 rich slurry separated from the mother solution was sent to the stripper for CO2 desorption at elevated temperatures (>140℃). The kinetics of KHCO3 crystallization and the solubility of KHCO3 both were investigated under typical operating conditions. The resultant data were fit to a size dependent crystal growth model, and applied to perform the crystallizer design analysis for the proposed carbonate based CO2 absorption process. The liquid-solid process had drawbacks related to issues incurred by the slurry operation. Therefore, additional research efforts were focused on studying the liquid-liquid phase transition which constitutes the major part of this dissertation. The first step was to select the proper liquid-liquid phase transitional (i.e., biphasic) solvents. A feasible biphasic solvent that is subject to a liquid-liquid phase separation during CO2 absorption can be a blend of compounds “A” and “B”. Compound “A”, containing primary or secondary amino groups, acts as an absorption accelerator. Compound “B”, containing tertiary amino groups, serves as a promoter for solvent regeneration. A screening study was conducted using a large pool of candidate compounds “A” and “B”. The aqueous blends of “A” and “B” were investigated with respect to their performance of CO2 absorption (i.e., rate and capacity), CO2 desorption (i.e., CO2 desorption pressure) and phase separation behavior. The qualitative relationship between the solvent structure and performance was evaluated. A polyamine based compound “A” was indispensable for liquid-liquid phase separation. The compound “A” with 4 to 6 carbon atoms and up to 3 nitrogen atoms favored the performance of its solvent blend. A further screening study was conducted using two aqueous biphasic solvents, with diethylenetriamine (DETA) as the common absorption accelerator. The first solvent blended N,N,N′,N′′,N′′-pentamethyldiethylenetriamine (PMDETA) as the… Advisors/Committee Members: Wang, Xinlei (advisor), Wang, Xinlei (Committee Chair), Lu, Yongqi (committee member), Kenis, Paul (committee member), Tumbleson, Mike (committee member), Singh, Vijay (committee member).

▼ ENGLISH ABSTRACT: The generation of ultrafast light pulses and the development of time resolved spectroscopic techniques, such as the femtosecond pump probe spectroscopy technique, have facilitated the study of ultrafast energy transfer in the photosynthetic systems of green plants and photodynamic therapy drugs. It has allowed the investigation of biological and chemical processes that take place on the ultrafast timescale and has allowed us to obtain spectral and kinetic information on energy transfer. In addition, it has allowed time resolved experiments in which the transient absorption of species under investigation was observed and has elucidated molecular dynamics. In the present work this was done with a temporal resolution of approximately 200 fs and covering a pump-to-probe delay range of 300 fs to 2 ns. The main aims of this study were to characterise the femtosecond pump probe spectroscopy system, to investigate the energy transfer in the natural light harvesting complex II (LHC II) in view of future expansion to the study of synthesized arti cial functional light harvesting complexes and nally to study ultrafast processes in zinc phthalocyanine (ZnPc) systems. In photosynthetic organisms, LHC II is the most abundant light harvesting complex and it plays an important role in light harvesting and photoprotection. The light energy is absorbed by light harvesting complexes and transferred to a reaction centre (RC) in an ultrafast timescale. Phthalocyanines are a new class of photosensitiser used for photodynamic therapy. These drugs are used to treat small and super cial tumours. The energy transfer from the singlet excited state to the triplet excited state occurs on an ultrafast timescale. However, recent work done on zinc phthalocyanine has proved that the determination of the ultrafast component remains a challenge. Several ultrafast studies carried out on ZnPc in solvents have been not only unsuccessful to give a clear picture of the ultrafast dynamics but have also produced divergent results. In this study, a characterisation of the femtosecond pump probe spectroscopy setup was done. The samples under investigation were probed by a white light continuum. The generation of the white light continuum introduced chirp, which in uenced the temporal evolution of the transient absorption results. The technique used to correct the chirp introduced by white light generation is discussed in detail. Our femtosecond pump probe spectroscopy setup was benchmarked by using a well known dye, namely malachite green. In addition, the investigation of the transient absorption change of LHC II, an active component in photosynthesis, as extracted from spinach leaves and the ultrafast dynamics of a promising photosensitiser ZnPc in dimethyl sulfoxide (DMSO) as well as in dimethyl formamide (DMF) was done. The spectral and dynamic results obtained using these three samples are described and exponential ts to the absorbance decay curves used to estimate the timescales of the energy… Advisors/Committee Members: Du Plessis, Anton, Steenkamp, Christine M., Rohwer, Erich G., Stellenbosch University.

▼ Beach vitex [Vitex rotundifolia (L.f.)] is a perennial woody shrub native to Hawaii and countries of the Pacific Rim. Beach vitex thrives on coastal sand dunes and was introduced into the southeastern United States for use as an ornamental and dune stabilizing plant. Today, however, it is considered a noxious weed and invasive species due to its aggressive spread and competition with native flora and fauna. Field and greenhouse studies were conducted from 2006 through 2008 to evaluate the efficacy of selected herbicides and mixtures on beach vitex. In one experiment, beach vitex control at 1 month after treatment (MAT) was greatest with glyphosate and glyphosate plus imazapyr (73% to 84%) and at 12 MAT, control increased to 90 and 94%, respectively. Control with triclopyr mixtures was less than 36% at 1 MAT and less than 11% at 12 MAT. In a second experiment, at 1 MAT glyphosate, imazapyr, and metsulfuron controlled beach vitex 66 to 82%. Control with aminopyralid, imazamox, and penoxsulam was less than 50%. At 8 MAT greatest control was observed with glyphosate and imazapyr (83 and 90%, respectively). Control levels with other treatments were significantly lower at 19 to 52%. In a greenhouse study at 3 weeks after treatment (WAT), control was 37 to 68% with glyphosate and 41 to 76% with imazapyr. At 5 WAT, control was 34 to 87% with glyphosate and 48 to 95% with imazapyr. Dry weight was 4.47 to 5.00 g in glyphosate treatments and 3.50 to 6.18 in imazapyr treatments as compared to the nontreated dry weight of 6.93 g. The absorption and translocation of glyphosate in beach vitex was evaluated with cut stem and foliar applications. Plants were treated with a prepared 14C-glyphosate solution and harvested at 6, 24, 48, 92, and 196 hours after treatment (HAT). In beach vitex cut stems, time of harvest was not significant indicating that all absorption and translocation occurred within the first six hours after treatment. The greatest amount of herbicide recovered remained in the stump (348,408 DPM). A moderate amount translocated to the first root section (14,572 DPM) and a minimal amount translocated to root segments greater distances from the stump (1,657 and 617 DPM for second 10 cm of roots and end roots, respectively). In foliar treatments, the greatest recovered herbicide remained in the treated leaf at 17,828 DPM. Recovered 14C-glyphosate in other plant parts did not differ and ranged 1,222 to 4,300 DPM. At 6 and 24 HAT, 2,081 to 2,825 DPM were recovered. Greater amounts of 6,432 to 9,661 were recovered at 48 to 196 HAT. Translocation of the applied herbicide was generally low with both application methods. Another invasive plant common to coastal areas of the southeastern United States is common reed [Phragmites australis ((Cav.) Trin. ex Steud.)]. Often referred to as Phragmites, this perennial emergent aquatic grass is spread worldwide. Field studies were conducted in 2006 and 2007 to evaluate efficacy of selected herbicides on Phragmites. At 12 to 16 WAT, Phragmites was controlled at least 93% with imazapyr at… Advisors/Committee Members: Dr. Robert Richardson, Committee Chair (advisor), Dr. Joseph Neal, Committee Member (advisor), Dr. David Jordan, Committee Member (advisor), Dr. Kurt Getsinger, Committee Member (advisor).
