Akouche, Mariame. „Synthèse prébiotique de Ribonucléotides sur des surfaces minérales“. Thesis, Paris 6, 2016. http://www.theses.fr/2016PA066609/document.
Der volle Inhalt der QuelleIn the « RNA world» prebiotic scenario, ribonucleotide polymers are considered as the first biochemical species to have emerged. However, in aqueous solution, their formation through conventional mechanisms of condensation is thermodynamically forbidden. Several synthesis pathways of nucleotides have been described in aqueous solution; most often, they involve chemically activated molecules. Another pathway to nucleotides implies mineral surfaces, which have been considered in prebiotic processes at least since the work of Bernal in 1951. However, these studies have hardly tried to understand surface-molecule interactions and consequently, thermodynamic and/or catalytic effects of mineral surfaces are not well rationalized. In the context of Bernal's hypothesis, we present for the first time an in-situ study of the thermal reactivity of nucleotides “building blocks” adsorbed on mineral surfaces (amorphous silica, saponite) emphasizing the synthesis of nucleotides without chemical activation. In our work, we first show that mineral surfaces are able to trigger the formation of inorganic polyphosphates from monophosphates at moderate temperatures. On the other hand, adsorption of ribose on silica surface improves its thermal stabilization. While ribose decomposes at 90°C in aqueous solutions, it is stable up to 200°C on silica (in the presence of ZnCl2). Secondly, we have demonstrated the formation of PRPP, as important reaction intermediate, by co-adsorption of ribose and inorganic phosphate on the silica surface. Finally, we showed the glycosylation of adenine to adenosine and the formation of AMP (i.e. simultaneous glycosylation and phosphorylation) after co-adsorption of their components on both mineral surfaces employed. A preliminary study even suggests that nucleotide dimerisation can occur in the same conditions

Der volle Inhalt der QuelleIndane is a molecular family with a particular importance in organic chemistry. Among them indane-based push-pull dyes have been extensively studied for non-linear optical devices and in solar cells purposes. Some of them, based on indane-1,3-dione core, have also emerged as photoinitiators in photopolymerization with encouraging results but few indane-based dyes were used later on. In this context, indane based push-pull, activable in the all visible range, may have a role to play. At the same time, indanes are well-known to form truxenes, an important motif for nanomaterials, which is why these molecules are seriously considered as synthon for surface chemistry applications. Moreover, the use of the s-indacene-1,3,5,7(2H,6H)-tetrone, also called “INDO4”, showed a multiple reactivity depend of the nature of the surface. Even if none of the oligomer observed were truxene motifs, a different comportment could still be expected by depositing an indane with a different geometry or nature. Considering the possibility of utilisation in photopolymerization and in surface chemistry, this thesis will treat of the synthesis of various structure in order to obtain the desired properties for these applications
Mouhat, Kawtar. „Elaboration de réseaux bidimensionnels covalents organiques sur surface“. Thesis, Aix-Marseille, 2016. http://www.theses.fr/2016AIXM4752.
Der volle Inhalt der QuelleNowadays, the engineering of nanometer-sized systems is a promising field for the development of little-sized systems. The possibility of extending these systems to applications such as molecular electronics or surface property tuning has attracted much attention to the scientific community. However, in order to construct complex electronic devices from organic molecules, covalent assembly of building blocks on surface is primordial. The researches carried out in this work thesis rest on the construction of two-dimensional frameworks from molecular building blocks deposited on surface. The achievement of such networks consists, first of all, in the synthesis of different precursors and afterwards, in the deposition of these molecular buildingblocks on metallic or graphite surfaces. The growth of such networks is controlled by changing deposition conditions which occurs in ultra-high vacuum or in liquid media. The framework can be built from the precursor itself, which reacts with each other to give rise to the network. Reactions such as self-condensation, oxydative polymerization or either cyclotrimerization are broached. Moreover, reactions between two different precursors are also described. After molecular building block synthesis, on-surface study is detailed which framework characterization is followed by scanning tunneling microscopy
Delgado, Marco. „Complexes d'hafnium supportés sur γ-alumine : synthèse, caractérisation et application en polymérisation des oléfines“. Thesis, Lyon 1, 2010. http://www.theses.fr/2010LYO10025.
Der volle Inhalt der QuelleNew well-defined hafnium alkyl and hydrid complexes supported on γ-alumina dehydroxylatedt at 500°C, γ-Al2O3-(500°C), have been prepared. The structure of the surface complexes obtained by grafting Hf(CH2tBu)4, 1, on γ-alumina has been resolved by a combined experimental (mass balance analysis, labeling, in situ IR, NMR) and theoretical (DFT calculations) study. Thermolysis, oxidation and hydrogenolysis reactions have unambiguously proved the presence of two kinds of neopentyl-metal bonds: Hf-CH2tBu and Al-CH2tBu. Three coexisting surface complexes have been fully characterized and quantified: a monoaluminoxy- [(≡AlIVO)Hf(CH2tBu)3], a neutral bisaluminoxy [(≡AlIVO)(AlsO)Hf(CH2tBu)2], and a zwitterionic bisaluminoxy complex [(≡AlIVO) (AlsO)Hf(CH2tBu)2]+[(CH2tBu)Als]- in 40 %, 26 %, and 34 %, respectively. Hydrogenolysis reaction of these complexes leads to the formation at 150°C of [(AlsO)3HfH], (70-80%) and [(≡AlIVO)(AlsO)Hf(H)]+[(CH2tBu)Als]- (20-30%). All these hafnium alkyl and hydrides are active in α-olefin polymerization in absence of a co-catalyst

Der volle Inhalt der QuelleAbstract : This thesis deals with investigation, by means of Scanning Tunneling Microscopy in ultra-high vacuum and Atomic Force Microscopy at ambient conditions, of supramolecular networks based on molecular self-assembly on different kinds of surfaces, such as: Au(111), Si(111)-B and HOPG, as well as investigation of on-surface synthesis of covalently bonded nanostructures. The first chapter presents state-of-the art of noncovalent molecule-molecule interactions that govern supramolecular self-assembling and methods to obtain covalently bonded self-asselblies on surfaces. The second chapter presents theoretical concepts and experimental setups, procedures for preparing clean surfaces, probes and molecular deposition in ultra-high vacuum system and ambient conditions, respecitvely.The third chapter is dedicated to results obtained by STM in UHV system and comparing investigation of supramolecular self-assembling of dipolar LdipCC molecules on Au(111) and Si(111)-B surfaces. Due to suitbale balance between contemplating choice of underlaying substrate and molecule-molecule interactions, LdipCC molecules self-assembled into extended and periodical supramolecular networks on both surfaces. On Au(111) surface, LdipCC molecules formed extended, porous supramolecular network which is govern by molecule-molecule interactions while on n Si(111)-B surface, LdipCC molecules self-assembled into homogenious, extended parallel alingment of molecular dipoles due to significant role of molecule-surface interactions. The fourth chapter is dedicated to the results obtained in ambient conditions which are monitored by AFM Peak Force Tapping mode. Two alkylated molecules, one bearing ethylene moieties and another possesing epoxied moiety, self-assembled into two-dimensional networks on HOPG surface. Ethylene based supramolecular network was exposed the thermal procedure while epoxy based supramolecular network was exposed to UV-light exposure. The proposed mechanisms based on analysis of topography and adhesion AFM images suggest that thermally induced on-surface cycloaddition reaction and UV-light initiated polymerization occurred on HOPG surface. In such a way, two-dimensional self-assembled networks on HOPG surface were converted into covalently bonded supramolecular self-assemblies

Der volle Inhalt der QuelleIn computer graphics where a part of the community focuses on artificially reproducing nature by the mean of computers, natural phenomena (such as wind, ocean, fire and smoke) are of great importance due to their omnipresence in every day’s life. In this scope, droplets are no exception as one can observe them in many occasions and many forms (dew, rain, shower burst, ice cube falling in a cocktail etc. ). Despise the small scale at which the phenomenon occurs, droplets can not be neglected in computer graphics if perception, photo-realism or immersion are seeked. A droplet flow will behave in a suprising complex way, its shape as well as its dynamic being rich in possibilities and oftenly described as unpredictable. In the scope of this thesis, two methods for droplets animation in computer graphics have been explored. In order to understand the essence of the phenomenon and to list the predominant phenomenological caracteristics, a preliminary study in physics (brief for the physicist but suffisant for the infographist) has been necessary. From the understanding of the phenomenon in the sens of the physics as well as the analyse of previous works dedicated to on-surface flows in computer graphics, some limitations have been emphasized which in turn have led to the development of two novel methods different in both concept and scope. The first method is empirical and performs in real-time, it tackles the problem of on-surface flows on planar surfaces. The principal motivations behind this work was the performance issues, which in consequence lead us to pose some hypotheses as well as to consider some simplifications relatively to the phenomenon. This method is aimed at being part of critical time applications where performances are prefered over realism such as in a drive simulator or a video game. In order to animate in a more convincing and realistic way the flow of the droplets, a second method physically based has been explored. As it is in general the case in computer graphics, such methods allows one to attain a great degree of realism at the price of a high computational cost, thus dedicating this type of methods to offline rendering. By inspiring ourselves from the litterature present in the computational fluid domain as well as thoroughly analysing the only method physically based in computer graphics for the animation of droplets on surfaces, we propose in this second method to overcome some limitations with respect to the computational and memory complexity as well as the correctness of the shape of the flow. In conclusion, we present the perspectives that have arised from the development of these two methods
