WISE J104915.57-531906.1 is the nearest brown dwarf binary to our solar system, consisting of two brown dwarfs in the L/T transition: Luhman 16A and B. In this paper, we present the first map of Luhman 16A, and maps of Luhman 16B for two epochs. Our maps were created by applying Aeolus, a Markov-Chain Monte Carlo code that maps the top-of-the-atmosphere (TOA) structure of brown dwarf and other ultracool atmospheres, to light curves of Luhman 16A and B using the Hubble Space Telescope's G141 and G102 grisms. Aeolus retrieved three or four spots in the TOA of Luhman 16A and B, with a surface coverage of 19%-32% (depending on an assumed rotational period of 5 hr or 8 hr) or 21%-38.5% (depending on the observational epoch), respectively. The brightness temperature of the spots of the best-fit models was similar to 200 K hotter than the background TOA. We compared our Luhman 16B map with the only previously published map. Interestingly, our map contained a large TOA spot that was cooler (Delta T similar to 51 K) than the background, which lay at low latitudes, in agreement with the previous Luhman 16B map. Finally, we report the detection of a feature reappearing in Luhman 16B light curves that are separated by tens of hundreds of rotations from each other. We speculate that this feature is related to TOA structures of Luhman 16B.

Les radicaux OH et HO2 jouent un rôle essentiel dans beaucoup de processus d’oxydationdans l’atmosphère. La dégradation des composés organiques volatils dans les conditionstroposphériques est généralement initiée par la réaction avec les radicaux OH, suivie par la réactiondes produits d’oxydation avec l’oxygène. Dans le cadre de cette thèse, des études ont été menéesafin de mieux comprendre les mécanismes d’oxydation d’espèces d’intérêt atmosphérique. Pour cela,un système expérimental de photolyse laser couplée à des techniques spectroscopiques de détectionrésolues dans le temps : Continuous Wave Cavity ring-down Spectroscopy (cw-CRDS) pour HO2,Laser Induced Fluorescence (LIF) pour OH et spectroscopy UV pour l’adduit Hexamethylbenzene-OH(HMB-OH) ont été utilisés. Différents systèmes chimiques ont été étudiés en utilisant ce dispositif expérimental : 1) laréaction d’HO2 avec CH2O, 2) la photolyse à 248 nm de l’acétaldéhyde et 3) la dégradation de HMBinitiée par OH. Les techniques de cw-CRDS et d’absorption UV ont été utilisées respectivement pourmesurer les sections efficaces de CH2O et de l’adduit HMB-OHOH and HO2 radicals play a vital role in many oxidation processes in the atmosphere. Thedegradation of volatile organic compounds under tropospheric conditions is induced by reaction withhydroxyl radicals followed by the subsequent chemistry of the initial OH oxidation products with O2.This thesis deals with the kinetic study of some of these atmospherically relevant reactions to betterunderstand their oxidation mechanisms using experimental techniques such as laser photolysiscoupled to detection by Laser Induced Fluorescence (LIF, for OH), continuous wave- Cavity RingdownSpectroscopy (cw-CRDS, for HO2) and time resolved UV spectroscopy (UV, forHexamethylbenzene-OH adduct). Different chemical systems have been studied using the above techniques: 1) the reaction ofHO2 radicals with formaldehyde, 2) the 248 nm photolysis of acetaldehyde and 3) the OH initiatedoxidation of Hexamethyl benzene. In addition to this, the spectroscopic application of cw-CRDStechnique and UV spectroscopy has been used for the measurement of absorption cross section ofselected absorption lines of formaldehyde in the near infrared region and Hexamethylbenzene-OHadduct in the UV region respectively

This thesis is concerned with the kinetic investigation of gaseous alkaline-earth atoms in specific electronic states by time-resolved spectroscopic methods. The first part of the thesis is directed towards a study of the collisional behaviour of ground state atoms, in particular, Sr[5s2(1S0)], generated by pulsed irradiation and monitored by time-resolved atomic resonance absorption spectroscopy. In broader terms, it was also envisaged that this would provide a framework for considering and comparing the behaviour of this atom in both ground and excited state reactions, especially that of Sr[5s5p(3PJ)], described later in the thesis, in order to investigate the relationship between collisional behaviour and electronic structure. Whilst this method did not yield data for Sr[5s2(1S0)], the investigation did provide a structure for considering alkaline-earth atom chemistry in general. The second part of the thesis describes the study of the collisional behaviour of the electronically excited strontium atom, Sr[5s5p(3PJ)], generated by pulsed laser excitation at elevated temperatures. The reactions of this optically metastable atomic state with the molecules CH3Cl, CF3Cl, CH3Br and CF3Br were studied by both time-resolved atomic emission from Sr[5s5p(3P1)] → Sr[5s2(1S0)] and time-resolved molecular chemiluminescence from SrX(A2Π1/2,3/2, B2Σ+ - X2Σ+), following halogen atom (X = Cl, Br) abstraction. Quantitative characterisation of the time-dependencies of the atomic and molecular emissions indicated direct halogen abstraction by Sr(53PJ). Branching ratios into these specific molecular electronic states were derived by computerised integration of the intensities of the atomic and molecular decay profiles and were shown to be statistical in nature.

The solvent-solute interface of a biomolecule is a dynamic but yet highly structured domain that links a chemically diverse solute surface to the chemically homogeneous bulk aqueous phase. The role of the resulting intermediate domain, i.e. the "hydration shell", in regulating DNA structure and recognition has been addressed here by time-resolved infrared spectroscopy. A highly reproducible automated hydration pulse regime was established and implemented for attenuated total reflectance (ATR) Fourier transform infrared (FTIR) spectroscopy to monitor the structural response of DNA to an incremental growth of its hydration shell on its intrinsic time scale of seconds. The transition from the crystallographically defined BI to the BII substate of B-DNA was found to be driven by the increase of water disorder upon growth of the hydration shell, derived from the water OH-stretching absorption frequency and band width changes. 2D correlation analysis was used to identify different water clusters from the temporal behaviour of their water OH stretching frequencies. The results show that BII-stabilizing structural constraints are exerted by strong water-DNA H-bonds in the grooves of B-DNA and are relieved when the groove-bound water merges into a contiguous hydration shell with the less H-bonded PO2- -solvation sphere at ~14 water molecules per DNA phosphate. The H-bond imbalance at the disjunct hydration sites is split symmetrically around the average H-bond strength of bulk water. Thus, merging into a contiguous hydration shell proceeds at little enthalpic cost and homogeneous connectivity to the outer bulk-like H-bond network, such that alteration in the network distant from the DNA can regulate the BI-BII transition in a cooperative manner. The water connectivity is disrupted by DNA-binding peptides. Remarkably, the data show that the replacement of hydration shell water upon ligand biding is crucial in conferring substate specific recognition by peptides that have little intrinsic structural preference. The antibacterial peptide indolicidin secreted from bovine neutrophils dehydrates the non-PO2--bound hydration sites, thereby rendering the unstructured peptide highly specific for the BI state with vibrational signature almost identical to the bacterial minor groove binder netropsin. The proposed dominant role of hydration shell water for DNA conformation was challenged by studying the competing effect of structured water in the coordination-shell of the lanthanide Eu3+ on water structure in the DNA hydration shell. Whereas no effect is seen at low hydration, a hydrogen-like phase is formed at a stoichiometric ratio of Eu3+ :DNA:H2O of 1:10:140, characterized by a strong increase of the molar volume of hydration water. This novel phase appears attractive for lanthanide and possibly actine separation approaches based on biomolecular coordination.

Research on the characterisation and understanding of pulsed magnetron discharges used for the deposition of thin, especially dielectric, films has been carried out between 2003 and 2008 at Chemnitz University of Technology. This thesis is a collection and summary of the original research during this period. In the main part of the thesis, work published in peer-reviewed scientific papers is summarised and yet unpublished results are given in more detail. Different aspects highlighted in the publications are described in a general context of the characterisation of the pulsed discharges for the principal understanding. The cross-linking of the published results is addressed and where necessary extensions to the publications are given. The main part is organised in three sections. In the first one, basics of pulsed magnetron discharges, their application, and important questions are summarised. The second section describes general results and physics of the discharges that have been obtained during the research work. It also emphasises the successful development or modifications of experimental techniques for the time-resolved characterisation. The third section addresses the possibilities to modify and control the process by external parameters that are typically accessible during the application or required by it. An appendix to the thesis comprises selected published research work which is made available as reprints of the original publications.

ChemistryPh.D.
Understanding molecular interactions at the surfaces of cellular membranes, including adsorption and transport, is of fundamental importance in both biological and pharmaceutical studies. At present, particularly with respect to small and medium size (drug-like) molecules, it is desirable to gain an understanding of the mechanisms that govern membrane adsorption and transport. To characterize drug-membrane interactions and mechanisms governing the process of molecular uptake at cellular membranes in living organisms, we need to develop effective experimental techniques to reach quantitative and time-resolved analysis of molecules at the membrane surfaces. Also, we preferably want to develop label-free optical techniques suited for single-cell and live cell analysis. Here, I discuss the nonlinear optical technique, second-harmonic light scattering (SHS), for studying molecule-membrane interactions and transport of molecules at the membrane of living cells with real-time resolution and membrane surface-specificity. Time-resolved SHS can quantify adsorption and transport of molecules, with specific nonlinear optical properties, at living organisms without imposing any mechanical stress onto the membrane. This label-free and surface-sensitive technique can even differentiate molecular transport at individual membranes within a multi-membrane cell (e.g., bacteria). In this dissertation, I present our current research and accomplishments in extending the capabilities of the SHS technique to study molecular uptake kinetics at the membranes of living cells, to monitor bacteria membrane integrity, to characterize the antibacterial mechanism-of-action of antibiotic compounds, to update the molecular mechanism of the Gram-stain protocol, to pixel-wise mapping of the membrane viscosity of the living cells, and to probe drug-induced activation of bacterial mechanosensitive channels in vitro.

Nous avons travaillé sur le développement d’un instrument de mesure de la luminescence induite par un faisceau d’ions lourds (nucléons 12) et d’énergie de l’ordre du MeV/nucléons. Basé sur une méthode de comptage de photons uniques obtenus par coïncidences, le dispositif permet d’obtenir sur 16 voies à la fois un spectre en énergie dans le domaine proche UV-visible-proche IR (185-920 nm) et la réponse temporelle sur la gamme ns-µs, avec un échantillonnage de 100 ps. Des mesures en température peuvent être réalisées depuis la température ambiante jusqu’à 30K.Ce travail met particulièrement l’accent sur les méthodes d’extraction des données : Une fois montrée la nécessité de déconvoluer les signaux, on s’intéresse dans un premier temps à évaluer différents profils instrumentaux modélisés et reconstruit à partir de mesures. A cet effet, un travail de caractérisation temporelle de chaque constituant du dispositif est mené. Puis ces profils instrumentaux sont utilisés dans deux méthodes de déconvolution par moindres carrés d’abord puis par maximum d’entropie ensuite.Deux matériaux types sont testés : Le Titanate de Strontium pour l’étude de la dynamique de l’excitation électronique, et un scintillateur plastique commercial, le BC400, pour l’étude du vieillissement et de la baisse des performances en fonction de la fluence. Dans les deux cas on a pu mettre en évidence la présence d’une composante ultra rapide de constante de temps subnanosecondeWe developed an instrument for measuring the luminescence induced by a heavy ion beam (nucleons 12) and energy in the range of MeV / nucleon. Based on a single photon counting method obtained by coincidences, the device can provide in the same run a 16-channel energy spectrum in the UV-visible- IR region (185-920 nm) and a time-resolved response in the range of ns up to µs for each channel. Temperature measurements can be performed from room temperature down to 30K.This work places particular emphasis on data extraction methods: Once the need to deconvolve the signals demonstrated the evaluation of different instrument profiles (simulated and reconstructed from measurements) leads to a systematic temporal characterization of each component of the device. Then, these instrumental profiles are used in two deconvolution methods: least squares first followed by maximum entropy method.Two typical materials are tested: the Strontium Titanate for the study of the dynamics of the electronic excitation, and a commercial scintillator, the BC400, for the study of the aging and the decrease of performances with fluence. In both cases, we have been able to highlight the presence of an ultrafast component of subnanosecond time constant

NoThe objective of this review is to provide an overview concerning what the authors believe to be the most important photoelectrochemical techniques for the study of semiconductor nanoparticles. After a short historical background and a brief introduction to the area of photoelectrochemistry, the working principles and experimental setups of the various static and dynamic techniques are presented. Experimental details which are of crucial importance for their correct execution are emphasized, and applications of the techniques as found in the recent research literature as applied to semiconductor nanoparticles are illustrated.
