Dispositifs optoélectroniques à base de semi-conducteurs organiques en couches minces

Les petites molécules de type p à bandes interdites étroites sont de plus en plus perçues comme des remplaçantes possibles aux polymères semi-conducteurs actuellement utilisés conjointement avec des dérivés de fullerènes de type n, dans les cellules photovoltaïques organiques (OPV). Par contre, ces petites molécules tendent à cristalliser facilement lors de leur application en couches minces et forment difficilement des films homogènes appropriés. Des dispositifs OPV de type hétérojonction de masse ont été réalisés en ajoutant différentes espèces de polymères semi-conducteurs ou isolants, agissant comme matrices permettant de rectifier les inhomogénéités des films actifs et d’augmenter les performances des cellules photovoltaïques. Des polymères aux masses molaires spécifiques ont été synthétisés par réaction de Wittig en contrôlant précisément les ratios molaires des monomères et de la base utilisée. L’effet de la variation des masses molaires en fonction des morphologies de films minces obtenus et des performances des diodes organiques électroluminescentes reliées, a également été étudié. La microscopie électronique en transmission (MET) ou à balayage (MEB) a été employée en complément de la microscopie à force atomique (AFM) pour suivre l’évolution de la morphologie des films organiques minces. Une nouvelle méthode rapide de préparation des films pour l’imagerie MET sur substrats de silicium est également présentée et comparée à d’autres méthodes d’extraction. Motivé par le prix élevé et la rareté des métaux utilisés dans les substrats d’oxyde d’indium dopé à l’étain (ITO), le développement d’une nouvelle méthode de recyclage eco-responsable des substrats utilisés dans ces études est également présenté.

Percepção Ambiental em Museus Paisagens de Arte Contemporânea: a legibilidade dos museus Inhotim/Brasil e em Serralves/Portugal avaliada pelo público/visitante

This thesis nalyzes the wayfinding in Landscape Museum of Contemporary Art (MPAC), based on the Institute of Contemporary Art CACI, Minas Gerais, Brazil and the Museum of Contemporary Art of the Serralves Foundation, Porto, Portugal. The study focuses on the interrelationship of the public/visitors with the landscape, architecture and contemporary art museums in these, in order to understand visual perception and apprehension of such an environment for their users. For both were confronted documentation (visual and written) and people talk. The main hypothesis put forward is that the audience/visitor MPAC appreciates the interrelationship between the natural environment (park/garden) and built environment (the works of contemporary art and the galleries), giving equal value to both. To complement this, a second hypothesis is that during the visit to MPACS, visitors define their paths spontaneously, but strongly influenced by existing visual indicators (maps, signage and striking landscape elements), which facilitate the readability of space, which also contribute to the offered services and the experiences of similar institutions. The analytical basis of the research used the concepts of legibility (LYNCH, 2009), wayfinding (GIBSON, 2009; ARTHUR, PASSINI, 2002; WEISMAN, 1982), Experiential Cotinnum (TUAN, 1985), Space Bound (CRUZ PINTO, 2007) and habitus (BOURDIEU, 1992). Methodologically was used qualitative research (DEMO 2000) by means of a case study (YIN, 2005; STAKE, 1999) and participant observation (WHYTE, 2005). In the two institutions interviews with researchers and curators, behavior observation and questionnaires from employees, trainees, monitors and the public/visitor of the two museums were performed. Although partially referende the initial hypothesis, the research showed that the public/visitor value appears more natural environments, they experience a greater intensity and in addition to the factors listed in the second case, your perception and definition of paths suffer significant influence of emotional relations established with space. Generally the audience/visitor adapts easily to different demands of contemporary art exhibition in the two museums and the built environment (park/garden and museum) interferes with your reading path during the visit, perceived by the public/visitor condition as a factor that favors the enjoyment of works on different mounts (wayfinding), though often become a factor that hinders the legibility of the building and its built environment

Beech bark disease distribution and resistance in Michigan and fungal endophyte ecology of resistant and susceptible beech (Fagus grandifolia Ehrh.)

Beech bark disease (BBD), a non-native association of the fungal pathogen Neonectria faginata and the beech scale insect Cryptococcus fagisuga, has dramatically affected American beech within North American forests. To monitor the spread and effects of BBD in Michigan, a network of forest health monitoring plots was established in 2001 following the disease discovery in Ludington State Park (Mason County). Forest health canopy condition and basic forestry measurements including basal area were reassessed on beech trees in these plots in 2011 and 2012. The influence of bark-inhabiting fungal endophytes on BBD resistance was investigated by collecting cambium tissue from apparently resistant and susceptible beech. Vigor rating showed significant influences of BBD in sample beech resulting in reduced health and substantiated by significant increases of dead beech basal area over time. C. fagisuga distribution was found to be spatially clustered and widespread in the 22 counties in Michigan's Lower Peninsula which contained monitoring plots. Neonectria has been found in Emmet, Cheboygan and Wexford in the Lower Peninsula which may coincide with additional BBD introduction locations. Surveys for BBD resistance resulted in five apparently resistant beech which were added to a BBD resistance database. The most frequently isolated endophytes from cambium tissue were identified by DNA sequencing primarily as Deuteromycetes and Ascomycetes including Chaetomium globosum, Neohendersonia kickxii and Fusarium flocciferum. N. faginata in antagonism trials showed significant growth reduction when paired with three beech fungal endophytes. The results of the antagonism trial and decay tests indicate that N. faginata may be a relatively poor competitor in vivo with limited ability to degrade cellulose.

Edge enhancement improves disruptive camouflage by emphasising false edges and creating pictorial relief

Disruptive colouration is a visual camouflage composed of false edges and boundaries. Many disruptively camouflaged animals feature enhanced edges; light patches are surrounded by a lighter outline and/or a dark patches are surrounded by a darker outline. This camouflage is particularly common in amphibians, reptiles and lepidopterans. We explored the role that this pattern has in creating effective camouflage. In a visual search task utilising an ultra-large display area mimicking search tasks that might be found in nature, edge enhanced disruptive camouflage increases crypsis, even on substrates that do not provide an obvious visual match. Specifically, edge enhanced camouflage is effective on backgrounds both with and without shadows; i.e. this is not solely due to background matching of the dark edge enhancement element with the shadows. Furthermore, when the dark component of the edge enhancement is omitted the camouflage still provided better crypsis than control patterns without edge enhancement. This kind of edge enhancement improved camouflage on all background types. Lastly, we show that edge enhancement can create a perception of multiple surfaces. We conclude that edge enhancement increases the effectiveness of disruptive camouflage through mechanisms that may include the improved disruption of the object outline by implying pictorial relief.

Sistema informático de gestão e análise de genealogias

A selecção do tema e consequente trabalho de que emerge o titulo desta dissertação decorreu do facto de se ter tomado conhecimento da necessidade que os membros do projecto FCOMP-01-0124-FEDER-007360 - Inquirir da Honra: Comissários do Santo Oficio e das Ordens Militares em Portugal (1570 - 1773) tiveram para satisfazer alguns objectivos em particular relacionados com a Genealogia da rede de Comissários. O sistema de trabalho manual que até aqui era utilizado, continha uma quantidade considerável de informação complexa, descrevendo ao pormenor as características não só dos indivíduos, mas também do que estava associado ao mesmo, incluindo quem e como se relacionava com as demais figuras. O principal objectivo consistiu assim em responder à pergunta: "Como será possível efectuar uma gestão de toda a informação genealógica recolhida no papel e permitir a sua análise no computador, recorrendo a tecnologias que, por um lado sejam eficientes, e por outro, fáceis de aprender pelos utilizadores?". Para conseguir responder à questão, foi necessário conhecer em primeira mão, o universo da Genealogia e a forma como opera, para que posteriormente, se desenhasse e moldasse toda uma aplicação às necessidades do utilizador. No entanto, a aplicação não se centra apenas em permitir ao utilizador efectuar uma gestão, recorrendo a um sistema de gestão de bases de dados MySQL e permitir a análise genealógica "tradicional" em programas como o Personal Ancestral File. Pretende-se sobretudo, que o utilizador faça uso e responda às perguntas "do presente" esperando que a própria aplicação sirva de motivação para novas perguntas, com a integração da tecnologia XML e do Sistema de Informação Geográfico, Google Earth, permitindo assim a análise de informação genealógica no mapa-mundo. ABSTRACT: The choice of this essay's work subject is set on the need to accomplish determinate goals related with the Genealogy of the network lnquisition Commissioners on behalf of the project FCOMP-01-0124-FEDER-007360 members - Inquirir da Honra: Comissários do Santo Ofício e das Ordens Militares em Portugal (1570 - 1773)- To Inquire Honor: Inquisition Commissioners and the Military Orders in Portugal. The manual work system used till now presented a considerable amount of complex information, describing in detail characteristics not only of individuals but also of what is associated to it, including whoandhow. The main goal aimed at thus responding to: «How could it be possible to select and examine all the genealogical data registered on paper and allow it to be analyzed on computer, by means of technology that on one hand are efficient and on other hand easy to learn by its users? ». ln order to get to the answer to that matter, it was necessary to acknowledge firstly the Genealogy's universe so afterwards it could be possible to outline and shape an entire application to user needs. Nevertheless, the application does not only focus on allowing the user to carry out the system’s management, using MySQL database management system and allowing the "traditional" genealogical management in programs such as the Personal Ancestral File. Above all the user should get involved with it and answer the key questions of 'the present’ hoping that the application serves by itself as motivation to arouse new questions with the integration of XML technology and Geographic Information System, Google Earth, thus allowing the analysis of genealogical information worldwide.

Study and characterization of low molecular weight polymer solutions for application in lubricating oils

The aim of this thesis is to evaluate the possibility of using short linear polymer chains as additives in lubricating oil applications. Through previous works, it has been seen that they are particularly resistant to mechanical degradation, which is the main reason why lubricating oils need to be changed after a while. This is the main reason why they could be proposed as alternatives in the market. The results of this work have been split into two major phases: the first concentrated on characterizing a target product obtained through thermal degradation, starting from the original long chain parent polymer, and the second focused on the technological advancement of heat exchangers. Through the studies carried out, we’ve characterized our innovative polymers and the solutions made with them and base oil at different concentrations. The most promising result is that these short random coiled polymeric chains obey to a more general universal function which express the value of specific viscosity as function of a dimensionless quantity c/c*. For the design of the unit operation, several alternatives were proposed and these all shared the same final goal: cooling the polymer without the presence of oxygen to avoid oxidation and formation of unwanted substances. We’ve analyzed the main difficulties related to the presence of these highly viscous substances and, more importantly, how to deal with this situation (e.g. by considering radial static mixer or even more complex conformations).

Factors Controlling The Deposition Of Silk Fibroin Nanofibrils During Layer-by-layer Assembly.

The layer-by-layer technique has been used as a powerful method to produce multilayer thin films with tunable properties. When natural polymers are employed, complicated phenomena such as self-aggregation and fibrilogenesis can occur, making it more difficult to obtain and characterize high-quality films. The weak acid and base character of such materials provides multilayer systems that may differ from those found with synthetic polymers due to strong self-organization effects. Specifically, LbL films prepared with chitosan and silk fibroin (SF) often involve the deposition of fibroin fibrils, which can influence the assembly process, surface properties, and overall film functionality. In this case, one has the intriguing possibility of realizing multilayer thin films with aligned nanofibers. In this article, we propose a strategy to control fibroin fibril formation by adjusting the assembly partner. Aligned fibroin fibrils were formed when chitosan was used as the counterpart, whereas no fibrils were observed when poly(allylamine hydrochloride) (PAH) was used. Charge density, which is higher in PAH, apparently stabilizes SF aggregates on the nanometer scale, thereby preventing their organization into fibrils. The drying step between the deposition of each layer was also crucial for film formation, as it stabilizes the SF molecules. Preliminary cell studies with optimized multilayers indicated that cell viability of NIH-3T3 fibroblasts remained between 90 and 100% after surface seeding, showing the potential application of the films in the biomedical field, as coatings and functional surfaces.
