Abstract:
Pyrrolepolyamide-2′-deoxyguanosine hybrids (Hybrid2and Hybrid3) incorporating the 3-aminopropionyl or 3-aminopropyl linker were designed and synthesized on the basis of previously reported results of a pyrrolepolyamide-adenosine hybrid (Hybrid1). Evaluation of the DNA binding sequence selectivity of pyrrolepolyamide-2′-deoxyguanosine hybrids was performed by CD spectral andTmanalyses. It was shown that Hybrid3possessed greater binding specificity than distamycin A, Hybrid1and Hybrid2.

Abstract:
Explosive pollen dispersal is common in Urticaceae and they are thought to be wind-pollinated. Despite a lack of obvious mechanism for preventing cross-species pollination, putative hybrid species in Urticaceae are rarely documented. Here we described the first natural hybrid in Urticaceae Elatostema ×hybrida from Taiwan. Morphological characters in E. ×hybrida are intermediate between putative parental species: E. lineolatum var. majus and E. platyphylloides. Six hybrid populations of E. ×hybrida were found in Taiwan that exhibited largely overlapping distribution patterns with its putative parents. Phylogenetic analysis of chloroplast DNA showed that the hybrid species is more closely related to E. lineolatum var. majus suggesting that the latter is the maternal parent and that hybridization is unidirectional. The chromosome number of E. ×hybrida remains the same as its putative parents (2n = 26). We speculate that the examined hybrids are natural first-generation results of independent hybridization events. Based on the morphology, spatial distribution, DNA sequence data, pollen viability and cytological observations, we hypothesize that E. ×hybrida is derived from natural hybridization events between E. lineolatum var. majus (♀) and E. platyphylloides (♂).

Abstract:
Prior knowledge on heterosis and quantitative genetic parameters on maize lethal necrosis (MLN) can help the breeders to develop numerous resistant or tolerant hybrids with optimum resources. Our objectives were to (1) estimate the quantitative genetic parameters for MLN disease severity, (2) investigate the efficiency of the prediction of hybrid performance based on parental per se and general combining ability (GCA) effects, and (3) examine the potential of hybrid prediction for MLN resistance or tolerance based on markers. Fifty elite maize inbred lines were selected based on their response to MLN under artificial inoculation. Crosses were made in a half diallel mating design to produce 307 F1 hybrids. All hybrids were evaluated in MLN quarantine facility in Naivasha, Kenya for two seasons under artificial inoculation. All 50 inbreds were genotyped with genotyping-by-sequencing (GBS) SNPs. The phenotypic variation was significant for all traits and the heritability was moderate to high. We observed that hybrids were superior to the mean performance of the parents for disease severity (−14.57%) and area under disease progress curve (AUDPC) (14.9%). Correlations were significant and moderate between line per se and GCA; and mean of parental value with hybrid performance for both disease severity and AUDPC value. Very low and negative correlation was observed between parental lines marker based genetic distance and heterosis. Nevertheless, the correlation of GCA effects was very high with hybrid performance which can suggests as a good predictor of MLN resistance. Genomic prediction of hybrid performance for MLN is high for both traits. We therefore conclude that there is potential for prediction of hybrid performance for MLN. Overall, the estimated quantitative genetic parameters suggest that through targeted approach, it is possible to develop outstanding lines and hybrids for MLN resistance.

Abstract:
The article is a review of the data on synthesis and physiological activity of hybrid antioxidants. The introduction offers an explanation to the fact why, in some cases, it is necessary to add drug molecules with fragments responsible for various properties and aimed at various targets. A large group of hybrid antioxidants comprise stable nitroxyl radicals that behave as antioxidants in free-radical reactions of oxidation. Compounds of this type were synthesized extensively to form a group of antitumor agents. As a rule, the specific (antitumor) activity retained or even increased as compared with the initial compounds (without nitroxyl radicals); the toxicity decreased 5 to 10 times, which made it possible to apply the drug in considerably higher concentrations. There are reported data on nitroxyl derivatives of anthracycline antibiotics, antimetabolites, alkyl ting agents, and the recent results on platinum complexes with nitroxyl fragments. Much attention is given to hindered phenols with “buoyancy” properties, particularly, to biochemical effects, making them promising agents to treat Alzheimer’s disease.

Abstract:
This study was designed to assess the general limitations of somatic hybridization as one of the key technologies for genetic manipulation in plants. The limits of somatic hybridization against different taxonomic backgrounds, intraspecific to interfamilial, were also assessed. Protoplast culture studies provided essential information relating to the species cultural and morphogenetic capacity. several #elect Ion strategies for the recovery of somatic hybrid colonies/plants were developed and assessed using various combinations of protoplast sources and species in the genera Petunia, Nicotiana, Salpiglossis and Chrysanthemum. Morphological, cytological and biochemical analyses were performed to confirm the hybridity of plants or cell lines recovered following protoplasm fusion (using 4-5 methods) and selection.The somatic hybrid callus/plants were obtained at intraspecific to interfamilial levels by complementation to chlorophyll proficiency, together with media selection or complementation of nitrate reductase deficient mutants as follows; P. Hybrida var. Monsanto (+) P. hybrida cv. Blue Lace (intraspecific), P. hybrida var. Monsanto (+) P. inflata and P. parviflora (interspecific), P. parviflora (+) N. tabacum (intergeneric), S. sinuata (+) P. hybrida var. Monsanto, P. parodii and N. tabacum (intertribal), and C. morifolium (+) S. sinuata.From this study, it appeared that there were no taxonomic limits to the production and proliferation of somatic hybrid cell lines. However, obtaining morphologically normal hybrid plants met with limited success as the taxonomic relationships became more distant. The regeneration capacity of somatic hybrids seemed to be controlled by both parental species. Somatic incompatibility mechanism was also shown to operate on chromosome elimination. Such chromosome elimination may well be advantageous in plant improvement.

Abstract:
In the experiment were verified the application of probiotic preparation through a water supply for feeding of cock’s hybrids Ross 308, Hubbard JV and Cobb 500 in the chemical composition of the most valuable parts of the carcass. Probiotic was based on the strain Lactobacillus fermentum with containing of 1.109 cfu.g−1 and potentially components of maltodextrin and oligofructose in 1% concentration. Length of feeding period was 42 days. Cocks were fed an ad libitum with the same starter mixture HYD-01 to 21th day and from 22nd to 42nd day of feeding with mixture HYD-02 in powdery form. The average of protein content of breast muscle was highest in Hubbard JV hybrid (23.93 g.100 g−1), lower in Cobb 500 hybrid (23.90 g.100 g−1) and lowest in Ross 308 hybrid (23.73 g.100 g−1), without significant differences (P ≥ 0.05) between hybrids and hybrids groups. Effect of probiotics had increased the protein content (P ≥ 0.05) in breast muscle of Ross 308 and Cobb 500 cocks and at the Hubbard JV only lower doses application during the feeding. The average of fat content in 100 g of breast muscle was lowest in Cobb 500 hybrid (1.09 g), higher in Hubbard JV hybrid (1.28 g) and highest in Ross 308 hybrid (1.35 g). Effect of probiotic to reduce fat content in breast muscle of cocks was at Ross 308 hybrid (1.33 and 1.23 g.100 g−1), Cobb 500 hybrid (0.98 and 1.02 g.100 g−1) and in second experimental group at Hubbard JV hybrid (1.03 g.100 g−1) statistically significant (P ≥ 0.05) in compared with control group, but significantly (P ≤ 0.05) between hybrids Cobb 500 and Hubbard JV in the first test groups. The average of energy value in 100 g of breast muscle was highest in Hubbard JV hybrid (449.24 kJ), lower in Ross 308 hybrid (448.40 kJ) and lowest in Cobb 500 hybrid (441.45 kJ), without significant differences (P ≥ 0.05) between hybrids and hybrids groups. The average of protein content of the femur was highest in Ross 308 hybrid (18.56 g.100 g−1), lower in Cobb 500 hybrid (18.42 g.100 g−1) and lowest in Hubbard JV (17.54 g.100 g−1) without statistical significance (P ≥ 0.05). Significant differences (P ≤ 0.05) of the femur were found at lower dose of probiotics between cock’s hybrids Hubbard JV (16.95 g.100 g−1) and Ross 308 (18.48 g.100 g−1) in the protein content. The average of fat content in the femur was highest in Ross 308 hybrid (10.58 g.100 g−1), lower in Hubbard JV hybrid (10.51 g.100 g−1) and lowest in Cobb 500 hybrid (10.29 g.100 g−1) without significant differences (P ≥ 0.05) between hybrids and hybrids groups. The higher fat and protein content in 100 g of the femur in Ross 308 hybrid was ensured the highest energy value (710.88 kJ), lower in Cobb 500 hybrid (696.40 kJ) and lowest in Hubbard JV hybrid (689.77 kJ) without significant differences (P ≥ 0.05) between hybrids and hybrids groups. The verified probiotic preparation in the final analysis had not negative effect on the chemical composition of the most valuable parts of the carcase cock’s hybrids Ross 308, Hubbard JV and Cobb 500.

Abstract:
Les vésicules hybrides polymère/lipides sont des structures récemment développées dans la littérature. Idéalement, celles-ci peuvent présenter la biocompatibilité et la biofonctionnalité des liposomes, ainsi que la robustesse, la faible perméabilité et la versatilité de fonctionnalisation chimique conférées par les chaînes de copolymères. Cependant, à ce jour, les facteurs régissant la séparation des phases dans ces membranes hybrides ne sont pas bien compris. Dans ce travail, nous avons étudié en détail la formation et la séparation de phases dans les membranes de vésicules géantes (GHUVs) et de taille nanométriques(100nm) (LHUVs) constituées de phospholipides en phase fluide ou gel et de copolymères à base de poly (diméthylsiloxane) et de poly (éthylène glycol). Différentes architectures(greffée, tribloc) et masses molaires ont été utilisées. La séparation de phase a été étudiée sur les vésicules géantes à l’échelle micrométrique et nanométrique respectivement par microscopie confocale et imagerie de fluorescence résolue en temps (FLIM), tandis que pour les LHUVs, différentes techniques comme la diffusion de neutrons, la Cryo-microscopie et la spectroscopie de fluorescence résolue dans le temps ont été combinées. Nous avons pu montrer que la fraction lipide/polymère, l'état physique du lipide et la tension de la ligne aux interfaces lipide/polymère modulable par la masse molaire et l'architecture du copolymère sont les facteurs importants régissant la formation et la structuration des vésicules hybrides. Enfin, nous avons montré que les propriétés élastiques de la membrane peuvent être modulées via la composition polymère lipide
Hybrid copolymer/lipid vesicle are recently developed self-assembled structures that could present biocompatibility and biofunctionality of liposomes, as well as robustness, low permeability and functionality variability conferred by the copolymer chains. However, to date, physical and molecular parameters governing copolymer/lipid phase separation in these hybrid membranes are not well understood. In this work, we studied in detail the formation and phase separation in the membranes of both Giant Unilamellar Hybrid Vesicles(GHUVs) and Large Unilamellar Hybrid Vesicles (LHUVs) obtained from the mixture of phospholipids in the fluid (liquid disordered) or gel state (solid ordered) with various copolymers based on poly(dimethylsiloxane) (PDMS) and poly(ethylene glycol) (PEO) with different architectures (grafted, triblock) and molar masses. For GHUVs, phase separation at the micron scale and nanoscale was evaluated through confocal microscopy, and Fluorescence lifetime imaging microscopy technique (FLIM) respectively, where as acombination of Small angle neutron scattering (SANS), Cryo-transmission electron microscopy (Cryo-TEM) and Time-resolved Förster resonance energy transfer (TR-FRET) techniques was used for LHUVs. We demonstrate that the lipid/polymer fraction, lipid physical state, and the line tension at lipid polymer/lipid boundaries which can be finely modulated by the molar mass and architecture of the copolymer are important factors that govern the formation and structuration of hybrid vesicles. We also evidence that elasticity ofthe hybrid membrane can be modulated via the lipid polymer composition, through the use of micropipettes techniques

Abstract:
A noção de um sistema híbrido é centrada em torno de uma composição de comportamentos discretos e contínuos, Enquanto a dificuldade na modelagem de sistemas híbridos vem da diversidade destes sistemas, a mais promissora abordagem para mitigar este problema é desenvolver linguagens de modelagem expressivas e precisas. No entanto, desenvolver linguagens de modelagem expressivas e precisas não significa a necessidade de novas linguagens, pelo contrário, esta tese propõe semânticas precisas para subconjuntos de linguagens existentes. Subconjuntos são definidos porque expressividade e precisão geralmente conflitam. por exemplo, o tamanho e a complexidade de uma linguagem (relacionados à expressividade) podem ter consequências diretas no tamanho e complexidade de sua semântica (relacionados à precisão). Precisão significa uma semântica definida de acordo com um método formal estabelecido, além disso, reconhecendo a natureza de tempo real dos sistemas híbridos, a linguagem de modelagem deve permitir determinismo, previsibilidade e composição simples. Nesta tese, duas linguagens complementares são formalmente definidas por máquinas de estado abstrato (A8Ms). A primeira delas é chamada synchronous fUML e ela combina recursos síncronos para controle na fUML (foundational subset for- executable UML models) padronizada. A segunda delas, Hybrid fUML, é uma extensão conservativa da synchronous fUML, na qual equações algébrico-diferenciais (DAEs) são descritas usando-se um subconjunto da sintaxe concreta da Modelica, O subconjunto da Modelica é selecionado de tal forma que sua semântica é definida pela semântica matemática padrão. Hybrid fUML é uma linguagem de modelagem definida para permitir descrição e análise de visões sistêmicas de sistemas híbridos. A principal contribuição inovadora é o novo modelo de computação para extensões híbridas de linguagens síncronas, que é formalmente definido para Hybrid fUML. O novo modelo de computação é baseado no conceito enichrony, uma propriedade de modelos que permite a sincronização do tempo físico no ambiente e nos modelos. O novo modelo da computação permite determinismo, previsibilidade e composição simples de sistemas híbridos.
The notion of a hybrid system is centered around a composition of discrete and continuous behaviors. Although the difficulty in modeling hybrid systems comes from the diversity of these systems, the most promising approach to mitigate this issue is developing expressive and precise modeling languages. Nevertheless, developing expressive and precise modeling languages does not necessarily mean the emergence of a new language, on the contrary, this thesis proposes precise semantics for subsets of existent languages. Subsets of existent languages are defined since expressivity and precision usually conflict, e.g., the size and complexity of a language (related to expressivity) may have direct consequences on the size and complexity of its semantics (related to precision). Precision means a semantics defined according to a well stablished formal method, furthermore, recognizing the real-time nature of hybrid systems, the modeling language have to enable determinism, predictability and straightforward composition. In this thesis, two complementary languages are formally defined by abstract state machines (ASMs). The first one is called synchronous fUML and it blends synchronous features for control into the standardized fUML (foundational subset for executable UML models). The second one, hybrid fUML, is a conservative extension of synchronous fUML in which differential algebraic equations (DAEs) are described using a subset of Modelica concrete syntax. The subset of Modelica concrete syntax is selected in such a way that its semantics is defined by the standart mathematical semantics. Hybrid fUML is a modeling language defined to enable description and analysis of system views from hybrid systems. The main innovative contribution lies in the novel model of computation for hybrid extensions of synchronous languages, which is formally defined for hybrid fUML. The novel of computation enables determinism, predictability and straightforward composition of hybrid systems.

Abstract:
Les composites hybrides offrent un moyen efficace d'améliorer les propriétés mécaniques des matériaux composites. Cette thèse vise à comprendre le comportement mécanique et l'effet synergique offerts par de tels composites hybrides sous plusieurs conditions de chargement. L'accent est mis, non seulement sur la caractérisation mécanique, mais également sur le développement et l'optimisation de nouvelles générations de renforts hybrides, permettant ainsi une hybridation aussi bien au niveau des nappes, qu’au niveau des mèches et des fibres. Dans ce travail, les fibres de carbone et de verre sont choisies comme les deux types de renforts pour les composites hybrides. Les propriétés de ces fibres unitaires sont d'abord caractérisées pour étudier l'impact des procédés textiles. De nouveaux renforts unidirectionnels ont été fabriqués après avoir optimisé les procédés, tels que la technologie UD cousu et l'étalement des fibres. Les composites ont été fabriqués via RTM basse pression en utilisant une résine époxy. Les caractéristiques en raideur et en résistance des composites de référence, des hybrides inter-plis, intra-plis et fibre à fibre ont ensuite été caractérisées dans des conditions de charge quasi-statique en traction, compression et flexion. L'effet d’hybridation (synergique) a été évalué pour ces composites en comparant les propriétés du composite hybride avec un composite de référence en carbone. Afin de comprendre le comportement à rupture de ces composites dans différentes conditions de charge, une étude de fractographie a été réalisée. Les hybrides inter-plis font apparaître une légère augmentation de la déformation à rupture en traction mais présentent une synergie négative pour toutes les autres conditions. Les hybrides intra-plis montrent eux, un effet synergique pour les résistances à la traction et à la compression, sans réduire leur déformation à rupture. Un composite hybride fibre à fibre réalisé par étalement montre une performance mécanique supérieure par rapport à d'autres hybrides. Les résultats présentés révèlent les avantages potentiels de l'hybridation à différents niveaux et dispersions. Les résultats ouvrent une voie pour les futurs travaux sur les composites hybrides et leurs procédés
Hybrid composites offer an effective way of enhancing mechanical properties of composite materials. This thesis aims to understand the mechanical behaviour and synergistic effect offered by such hybrid composites in several loading conditions. The focus not only lies on mechanical characterisation but also on development and optimization of new generation of hybrid reinforcements thus allowing hybridization both at ply levels and at tow and fibre levels. In this work, carbon and glass fibres are chosen as the two types of reinforcements for hybrid composites. Single fibre properties of these fibres were first characterised to study the effect of textile processes. Novel unidirectional reinforcements have been fabricated after optimising the processes such as unidirectional stitching and spreading technology. Composites were manufactured via low pressure RTM process using an epoxy resin. Stiffness and failure characteristics of reference, interply, intraply and intermingled hybrid composites were then characterised in quasi-static tensile, compression and flexural loading conditions. The hybrid (synergistic) effect were evaluated for these composites by comparing the hybrid composite properties with a carbon reference composite. To understand the failure behaviour under different loading conditions, a fractography study was conducted. Interply hybrids slightly increase the failure strain in tension but demonstrate negative synergy in all other properties. On the other hand, intraply hybrids show a synergistic effect in both tensile and compressive strengths, while not reducing the failure strain. A spread tape intermingled hybrid composite demonstrates a superior mechanical performance when compared to other hybrids. The presented results reveal the potential benefits of hybridisation at different levels and dispersions. The results provide a driving force for future work on hybrid composites and their processing

Abstract:
Cette thèse propose la conception de lois de commandes hybrides pour les convertisseurs électroniques de puissance. Ce nouveau type de lois de commande est basé sur l'utilisation de modèles hybrides qui capturent les comportements dynamiques macroscopiques de ces dispositifs électroniques, essentiellement leur nature hybride. Dans le contexte de la régulation des convertisseurs DC-DC ou AC-DC, en appliquant la théorie des systèmes hybrides, il est ainsi prouvé que les lois de commandes proposées assurent la stabilité de la boucle fermée ainsi que certaines performances de type LQ. Pour un onduleur en demi-pont (convertisseur DC-AC), une loi de commande hybride est proposée afin que la tension de sortie suive une référence sinusoïdale souhaitée. Dans le cas d'une charge inconnue, une loi de commande adaptative est alors couplée à la commande hybride permettant l'estimation de la charge et donc une régulation ou un suivi de trajectoire plus précis. Notons que pour obtenir une régulation ou un suivi parfait, une fréquence infinie est souvent obligatoire pour les lois de contrôle proposées, ce qui est inappropriée en pratique. Pour résoudre ce problème, une régularisation de l'espace d'état ou du temps est ajoutée à la boucle fermée assurant un temps de maintien entre deux sauts consécutifs et réduisant ainsi considérablement la fréquence de commutation
This thesis proposes the design of hybrid control laws for power electronics converters. These new type of control laws are based on some hybrid models which capture the macroscopic dynamical behaviors of such electronic devices, essentially its hybrid nature. In the context of the regulation of DC-DC or AC-DC converters, applying the hybrid dynamical theory, the proposed control laws are proved to ensure the stability of the closed loop as well as some LQ performances. For a half-bridge inverter (DC-AC converter), a hybrid control law is proposed in order that the output voltage tracks a desired sinusoidal reference. In the case of unknown load, an adaptive control law is coupled to the hybrid control allowing the estimation of the load and therefore leading to a more precise regulation or tracking. Notice that in order to achieve a perfect regulation or tracking, an infinite frequency is often mandatory for the proposed control laws, which is inappropriate in practice. To tackle this problem, a space- or time-regularization are added to the hybrid closed-loop ensuring a dwell time between two consecutive jumps and reducing thus drastically the switching frequency

Abstract:
Paleontological documentation of hybridization events has the potential to address a multitude of evolutionary and paleobiological issues unanswerable by purely biological means. However, previous studies of modern hybrids suggest that their morphology is often insufficient for their reliable discrimination. This study analyzes the morphology of an extant, genetically-identified Mercenaria spp. (Bivalvia: Veneridae) hybrid zone using Bookstein coordinates and multivariate methods to answer two questions: (1) can hybrid Mercenaria spp. individuals be identified based on morphology alone, and (2) would a Mercenaria spp. hybrid zone be recognizable in the fossil record?

Multivariate statistical procedures (principal components analysis, canonical variate analysis, etc.) using Bookstein coordinates demonstrate that, within the hybrid zone, hybrid individuals cannot be identified due to extreme overlap with the parental taxa. The hybrid zone as a whole, however, can be identified by comparison with pure-species populations sampled from outside the hybrid zone. Hybrid zones occupy parental species morphospace plus intermediate morphospace. The technique of using multiple pure-species populations to establish species morphospace is introduced to control for processes that may also result in morphological intermediates at ecological time scales (dimorphism, ecophenotypy, and geographic variation). Four alternative causal explanations of morphological intermediates through geological time (primary intergradation, uncoupled genetic and morphological divergence, time-averaged evolving populations, and developmentally instable populations) are evaluated. A literature survey strongly suggests that neither time-averaging nor developmental instability is occurring at the beginning of a lineageâ s evolutionary history, and that hybridization may be much more extensive than paleontological data suggest.

Abstract:
Based on the upcoming 2010 World Expo of Shanghai. According to 'moving out' policy of Shanghai government, a large percentage of residents from Shanghai's old downtown area are being moved out to a district on the outskirts of the municipality. In the context of moving out policy and shifting community space of 'Longtang' residents, my research explores how water can be used to forge a new typology for the Xinji residential area in developing Shanghai. The new typology of residential area is defined by a new type of community space. Water, edge and corridor are examined as three main concepts to create this kind of new community space, where residents can be provided with diverse spatial experience and various spatial effects through spatial transformations in and between private and public and diverse programs in a residential area. 'Longtang' is one of the key precedents I am looking at for the purpose of studying water edge conditions and corridor conditions, and to deduce a way to best design hybrid community in the Xinji residential area, which is selected as my research site. It is identified as one of the peripheral node for the moving out policy by Shanghai government? My research, therefore, tries to explore a new typology of Xinji residential area, which can provide both existing residents and 'Longtang' residents with diverse water based community space in the residential area and its context.

Abstract:
En 2004, le carbone, la base de toute vie connue sur Terre, a marqué les esprits une fois de plus: Les scientifiques de l’Université de Manchester au Royaume Uni ont pu extraire une matière carbonée complètement nouvelle, le graphène à partir d’un morceau de graphite comme celui qui compose les crayons. À l’aide d’un ruban adhésif, ils ont obtenu une paillette de carbone de l’épaisseur d’un atome seulement, à une époque où beaucoup pensaient qu’un matériaux cristallin aussi fin ne pouvait pas être stable. Le graphène parfait est une couche monoatomique composée d’atomes de carbone hybridés sp2, arrangés en structure alvéolaire; sa structure chimique particulière lui donne des propriétés physiques et chimique remarquable. Le graphène est devenu rapidement la matière carbonée la plus intensivement étudiée parmi celles «possiblement révolutionnaires», avec ses applications potentielles s’étendant de la microélectronique aux composites, des énergies renouvelables à la médecine. En 2010, Geim et Novoselov ont été récompensés par le prix Nobel de physique pour leurs «expériences révolutionnaires sur les matériaux bi-dimensionnels en graphène» qui a ouvert une nouvelle ère dans la science des matières carbonées.La chimie non-covalente du graphène est exploitée et étudiée dans cette thèse dans le but de concevoir, produire, transformer et caractériser les nouveaux matériaux hybrides graphène-organique. L’étendue de ce travail couvre les aspects mécanistiques de l’exfoliation en phase liquide du graphène avec des colorants, les aspects fondamentaux des interactions entre le graphène et le chromophore, en phase liquide et solide, ainsi que l’élaboration de suspensions hybrides de graphène dans le but d‘applications en électronique organique et dans les matériaux composites polymères fonctionnels
In 2004, carbon, the basis of all known life on earth, has surprised once again: Researchers from University of Manchester, UK, extracted a completely new carbon material, graphene, from a piece of graphite such as is found in pencils. Using adhesive tape, they obtained a flake of carbon with a thickness of just one single atom, at a time when many believed it impossible for such thin crystalline materials to be stable. Pristine graphene is a mono-atomic sheet of, sp2 hybridized carbon atoms arranged in a honeycomb network; this particular chemical structure gives rise to its outstanding physical and chemical properties. Graphene rapidly became the most intensively studied among the ‘possibly revolutionary’carbon materials, with its potential applications reaching from microelectronics to composites, from renewable energy to medicine. In 2010, Geim and Novoselov were honored with the Nobel Prize in Physics for their “ground breaking experiments regarding the two-dimensional material graphene” that started a new era in the science of carbon materials.In this thesis we exploit and study the non-covalent chemistry of graphene to design, produce, process and characterize novel graphene organic hybrid materials. The scope of this work covers mechanistic aspects of graphene liquid phase exfoliation with dyes, fundamental aspects of graphene chromophore interactions in liquid and solid phase and the formulation of graphene hybrid suspensions towards application in organic electronics and functional polymer composite materials

Abstract:
The hybrid electric vehicle is changing the automotive market at an impressive rate. While not as highly publicized, the transit bus market is being transformed at an equally great rate. As these markets move forward, the school bus market remains largely unchanged. As an unchanged market, there is still the opportunity to optimize a hybrid vehicle platform for school buses. This study models an existing class C school bus and investigates the potential of both series and parallel hybrids to reduce fuel consumption and emissions. The primary focus of this study is to investigate the potential benefits of adding an electric grid interconnection to hybrid electric school buses, allowing them to add to the hybrid potential to a pre-charged battery pack. These vehicles are known as plug-in hybrids. The school bus models shown in this paper were generated in a Matlab/Simulink-based program developed by NREL called ADVISOR. ADVISOR is used by vehicle manufacturers as a tool to experiment with different vehicle configurations. In this study both a generic series hybrid and a generic parallel hybrid are generated and used in both charge-sustaining and charge-depleting scenarios with varying sizes of battery packs to increase the “grid energy.” The results of each model are presented by fuel economy and emissions reductions taking into account the power plant emissions and electricity costs. The results of the study show that by adding a plug-in connection to existing hybrids, significant savings can be achieved, both in fuel costs and in overall emissions. By analyzing the emissions at the power plant level and at the vehicle level we show that emission of NOx, Particulate Matter and Carbon Dioxide can all be reduced while saving on fuel costs. This study also shows that some models of traditional hybrid can be operated as plug-in models with little or no change to the system to gain significant benefit from the initial charge.

Abstract:
This technical paper provides a literature review on Hybrid Electric Vehicles and various hybrid topologies associated with it. Different kinds of hybrids are available in different parts of the world in various brand names. The main aim of this review is to identify the pros and cons of some prominent topologies that could pave a way to the proposition of new and efficient design. Results from the study indicate that hybrids have a potential to bridge the gap between pure gasoline vehicles to plug in electric vehicles leaving behind time for the technology to mature and to make improvements in the infrastructure for Eco-friendly vehicles.
