Étude de nouveaux matériaux poreux pour le développement de micro-colonnes en silicium pour la chromatographie en phase gazeuse / Study of new porous materials for silicon microfabricated column development in gas chromatography

Lefebvre, David 15 December 2014 (has links)
En chromatographie en phase gazeuse, la miniaturisation ouvre la voie pour de nouveaux appareils portables, consommant peu d'énergie et de gaz et permettant des analyses directement sur site en évitant ainsi le transport d'échantillons. Depuis les années 70, l'essentiel des travaux s'est focalisé sur les hydrocarbones les plus lourds, avec 5 atomes de carbones ou plus. Ce travail expose le développement de nouvelles phases stationnaires de silice mésostructurées pour la séparation des alcanes légers (avec moins de 5 atomes de carbones) dans des colonnes micro-fabriquées, suivant deux procédés diffrérents : i) le dépôt dynamique in-situ d'un sol directement dans les colonnes capillaires ou micro-fabriquées, ou ii) le dépôt couche-par-couche de nanoparticules de silices (SNPs) sur les micro-colonnes. L'influence des paramètres du dépôt sol-gel sur l'épaisseur finale du de la phase stationnaire a été étudiée sur des colonnes capillaires courtes. En modifiant la nature et la concentration de l'agent structurant, il a été possible d'obtenir différentes mésostructures plus ou moins ordonnées et de modifier le pouvoir rétentif de la colonne. Curieusement, les structures les moins organisées ont montré la rétention la plus importante vis-à-vis des alcanes, comparable à celle de colonnes commerciales, mais pour une épaisseur de phase stationnaire 30 fois plus faible. Le procédé a été adapté avec succès aux colonnes micro-fabriquées. Les colonnes obtenues montrent des efficacités de séparation prometteuses, et le plus grand nombre de plateau théorique par mètre (th.p./m) rapporté à ce jour pour l'éthane (7500 th.p./m). Finalement, un procédé alternatif par dépôt couche-par-couche a été étudié pour déposer directement des nanoparticules de silice comme phase stationnaire dans les micro-colonnes. Ce procédé a d'abord été évalué pour des SNPs commerciales non poreuses. Puis il a été appliqué avec succès au dépôt de SNPs mésostructurées, synthétisées au laboratoire, et validé pour le dépôt pleine-plaque de 35 micro-colonnes en simultané. Dans l'ensemble, ce travail démontre l'efficacité des phases stationnaires en silice mésostructurée pour la séparation des alcanes légers par des colonnes micro-fabriquées / Miniaturization in Gas Chromatography opens the way to low cost, low gas and low power consumption portable devices, which offer in-situ analysis and avoid tedious transport of samples to laboratories. Since the first micro-fabricated column in the late 1970’s, the main focus was directed to the separation of heavy molecular weight hydrocarbons, with 5 or more carbon atoms. In this work, we have developed sol-gel mesotructured silica stationary phases for the separation of light alkanes (from one to 5 carbon atoms) in micro-fabricated columns, following two different procedures: i) the deposition of a sol-gel thin film by dynamic coating directly into the GC capillary or on micro-fabricated columns or ii) the layer-by-layer (LbL) deposition of silica nanoparticles (SNPs) on micro-fabricated columns. The influence of the sol-gel process coating parameters on the final thickness of the stationary phase was studied on short capillary columns. Various ordered or disordered mesostructures were yielded by varying the nature and the concentration of the structure directing agent (SDA), thus allowing the obtention of columns with different retention strengths. Interestingly, the less organized layers led to the columns with the highest retention, comparable with commercial columns for stationary phases being 30 times thinner. The process was successfully transposed to micro-fabricated columns. The obtained micro-columns showed promising efficiencies and the highest number of theoretical plates per meter (th.p./m) reported to date for ethane (7500 th.p./m). Finally, we investigated an alternative way to coat GC micro-columns directly with mesostructured silica nanoparticles using an LbL process. The process was first evaluated for commercial non porous SNPs. Then it was successfully applied to mesostructured custom SNPs and further validated for the full-wafer simultaneous coating of 35 columns. Overall, this work demonstrated the use of mesostructured silica as an effective stationary phase for light alkane’s separation on GC micro-fabricated columns

Mellan fantasi och verklighet : Om begreppen fiktiv kulturmiljö, autenticitet och historiebruk / Between fantasy and reality : The concepts of fictional cultural environment, authenticity and use of history

Ida, Gustafsson January 2018 (has links)
The paper presents how the concept of fictional culture environment can be defined on the basis of a Swedish real and fictional cultural heritage. Three studies consisting of "mapping”, “categorization", "detailed study" and "comparison" defines and delimits the concept and presents a graphical comparison model. The study focuses on places taken from the stories of Astrid Lindgren. Their authenticity and historical use is analyzed and discussed. The line between reality and fiction has become more difficult to discern. The paper presents a new concept and a benchmark that can contribute to a clearer definition of our fictional cultural heritage. / Uppsatsen presenterar hur begreppet fiktiv kulturmiljö kan definieras med utgångspunkt från ett svenskt verkligt och fiktivt kulturarv. Tre delstudier bestående av ” kartläggning, kategorisering”, ”närstudie” och ”komparation” definierar och avgränsar begreppet samt presenterar en grafisk jämförelsemodell. Studien fokuserar på platser hämtade från sagor av Astrid Lindgren.  Platsernas autenticitet och historiebruk analyseras och diskuteras. Gränsen mellan verklighet och fiktion har blivit svårare att urskilja. Uppsatsen presenterar ett nytt begrepp och en jämförelsemodell som kan bidra till en tydligare definition av vårt fiktiva kulturarv.

Bamboo Housing: Building with Composites for Dignity and Longevity

Marggraf, Gregory Paul 26 October 2023 (has links)
This mixed methods thesis provides a cumulative study of bamboo as a natural material and building product through the lenses of architectural and product design, engineering, manufacturing, agriculture, material science, environmental science, history, and culture. All case study work is based in the context of coastal Ecuador. The main goal of the thesis is to explore an identified need for a bamboo relief housing system that has the attributes of longevity and quality, but is also rapidly deployable via pre-fabrication. This exploration is performed with the methodology of an in-country applied product and process design, physical prototyping of elements and joints, mechanical performance testing, a case study house design, and a comparative cost analysis with an alternative bamboo relief home. Results of these methods include a successful on-site fabrication process for cross-laminated floor panels installed into culm-frame structure, adequate floor system bending data for design incorporation, and a cost-effective design proposal compared to bamboo disaster-relief precedence. This thesis has the potential to be built upon to the result of real-world environmental, economic, and social impact. / Master of Science / This thesis addresses the use of bamboo in coastal Ecuador from the perspectives of architectural and product design, engineering, manufacturing, agriculture, material science, environmental science, history, and culture. Specifically focused on is the need for post-disaster bamboo housing that is factory-built, and therefore quickly deployable when needed, but also designed for durability and longevity, providing people with safe and dignified living conditions in times of severe need. It is concluded that the proposed system has merit, but will require further research and testing to prove its exact role in Ecuador and/or elsewhere. Ultimately, this work is important to solving greater global environmental issues such as increasing atmospheric CO2, increasing natural disaster frequency and intensity, and increasing human population and the accompanying housing demand.

Performance and Reaction Mechanisms of Solid Oxide Fuel Cell Cathodes Fabricated by the Impregnation Method

Zhang, Qi 08 1900 (has links)
<p> The exploration of cathode materials and fabrication methods plays an important role in the development of solid oxide fuel cell (SOFC) technology. The objective of this study is first to optimize the cathode microstructure by the impregnation method, and then investigate the potential application of copper manganese spinel as a new cathode material with optimized microstructure and explore the reaction mechanism of the cathodes.</p> <p> The impregnation method was employed to fabricate a composite cathode with electrocatalyst particles dispersed in a framework of electrolyte material. The impregnation method is relatively easy to apply and yield the optimized microstructure, allowing extended three phase boundary length and absence of secondary phase formation during fabrication.</p> <p> The polarization performance of copper manganese spinel (CMO) impregnated YSZ cathodes was examined by adjusting catalyst particle size, electrode thickness and catalyst content. A critical thickness of 16.9±2.0 μm for the CMO-YSZ composite cathode was calculated from Tanner's model. Decreased catalyst particle size and a thickness close to the critical value were found to eliminate polarization loss. The composite cathode with 50 wt% CMO impregnation showed a polarization resistance as low as 0.3 Ωcm^2 at 750°C. At 800°C, an SOFC with CMO-YSZ composite cathode had a power density of 172 mW/cm^2, which was 2.5 times higher than the cell with the traditional LSM-YSZ composite cathode under the same conditions.</p> <p> The cathode reaction mechanism of CMO-YSZ and strontium doped lanthanum ferrite (LSCF) impregnated Gd doped ceria ( CGO) composite cathodes was studied, using impedance spectroscopy, cyclic voltammetry and current interruption techniques. Surface diffusion and mass transfer were determined to be the rate controlling steps for CMO-YSZ composite cathode at low and high temperatures, respectively. A low frequency process at low temperatures and at least two processes at high temperatures were identified as rate determining steps of LSCF -CGO composite cathodes. A cathodic current activation effect was observed on CMO-YSZ cathode under current passage. The catalytic activity of CMO was enhanced by the cathodic current and the effect existed in both long-term and short-term experiments.</p> <p> The results of this study suggest that copper manganese spinel has attractive properties as a new catalyst material for the cathodic reaction with the composite structure obtained by the impregnation method.</p> / Thesis / Master of Applied Science (MASc)

Increasing the utilisation of hybrid concrete construction in South Africa

Hanekom, Rojean 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Hybrid concrete construction (HCC) is a construction technique that makes use of both in-situ and pre-fabricated concrete products by making optimum use of the advantages of both these methods in the same project. Although the advantages of this building method is well recognised throughout the world and a feasibility study illustrated that HCC is a suitable building method in South Africa, it remains under-utilised in the country. HCC encourages early involvement from the project team and provides clients with the best value projects and a "win-win" situation for the project team during the project development. The objective of this study is to identify barriers that prohibit an increased utilisation of HCC for the South African construction industry. Additionally, it provides possible solutions to overcome these barriers. These proposed solutions are similar to the programmes and methods that are implemented in other countries to improve their HCC utilisation. Furthermore, drivers are identified in this study to implement these solutions in the industry and a proposed "change model" is developed for private companies to assist with the change process. This study is unique because current South African conditions are used to establish the barriers and solutions. Furthermore, it takes into account that not all countries have such progressive construction industries as the European markets and therefore it considers solutions and drivers that are suitable for less advanced industries such as South Africa. The model that is proposed is applicable to any industry regardless of its nature or country. Although the United Kingdom is not the widest user of pre-fabricated concrete products, their HCC research is extensive, making it a suitable comparative country for the South African construction industry. During the investigation, the procurement methods in South Africa were found to be traditional and do not allow for early involvement or partnering in the project team. To obtain early involvement, it is critical to initiate methods such as design-and-build, contract management or public-private-partnerships during the procurement phase. Decision and design assistance from the whole project team and software tools are essential when HCC is considered. Because the South African construction industry does not provide such support it is advised here to incorporate contractors from an early stage and to develop software tools that can assist during the decision making and design process of HCC structures. The industry does not provide the project team with sufficient training programmes that increase knowledge of HCC. Training programmes that are cognitive stimulating must be developed for the industry. Furthermore, a database is required to illustrate the utilisation of different pre-fabricated products and in different projects within South Africa. Labour-intensive construction regulations and green building techniques (not compulsory) are promoted in South Africa. Labour-intensive programmes should consider the negative impact it has on the labourers and consider HCC as a building technique because the pre-fabricated elements are manufactured in a controlled and safe environment. It is advised that the toolkits that are used for green building accreditation, must be revised to accommodate the additional benefits such as less waste generation, that HCC offers to a project. Regardless of the country in which HCC is utilised, the environment must be acceptable for the innovation. By analysing the criteria that influences the use of HCC in a country and adding weighting functions to these criteria, the acceptability towards the innovation can be obtained. Furthermore, public clients and companies are recognised here as drivers of change. While public clients can commit to HCC for the cost, labour-intensive factories, green building methods, improved health and safety, training for labourers, private companies can utilise HCC to provide best value to a project. A model is proposed here for innovative companies that will allow them to change not only the company, but the industry towards a HCC "mindset". / AFRIKAANSE OPSOMMING: Hibriede beton konstruksie (HBK) is ’n tegniek waarby beide voorafvervaardigde betonelemente en in-situ beton in dieselfde projek gebruik word ten einde voordeel uit beide metodes te trek. Alhoewel die voordele van die konstruksietegniek wel bekend is in talle lande van die wêreld en ’n uitvoerbaarheidsanalise getoon het dat HBK ’n voordelige konstruksiemetode vir Suid-Afrika is, is dit tans onderbenut in die plaaslike sektor. HBK bied vir kliënte projekte van goeie waarde en omdat dit vroeë betrokkenheid verg vanaf die projekspan, resulteer dit ’n "wen-wen" situasie tydens die projekontwikkeling. Die doel van hierdie studie is om die hindernisse te ondersoek wat veroorsaak dat HBK nie meer gereeld in Suid-Afrika gebruik word nie. Ten einde die effekte hiervan te verminder, word moontlike oplossings vir hierdie hindernisse voorgestel. Die oplossings is gebaseer op tegnieke en metodes wat geïmplimenteer word in ander lande waar HBK gebruik word. Rolspelers wat hierdie verandering na HBK kan dryf word geïdentifiseer en ’n model om verandering binne ’n maatskappy te lei word voorgestel om die rolspelers te ondersteun tydens die proses. Hierdie studie is uniek omdat dit inligting gebruik van die huidige situasie van die Suid-Afrikaanse konstruksie-industrie om die hindernisse en oplossings te identifiseer. Omdat nie alle konstruksie-industrieë so vooruitstrewend is soos in Europese lande nie, is die oplossings en rolspelers relevant vir enige land wat ’n industrie het wat soortgelyk is aan Suid-Afrika. Die model wat voorgestel word is ook relevant tot enige industrie afgesien van die land waar nuwe tegnieke geïmplimenteer word. Alhoewel dit bevind is dat die Verenigde Koningkryk nie die grootste gebruikers van HBK is nie, is hulle navorsing in die veld omvattend. Daarom word die Verenigde Koningkryk beskou as ’n voorbeeld om Suid-Afrika se konstruksie-industrie mee te vergelyk, asook om inligting van HBK te verkry. Tydens die studie is bevind dat die projekaanstellingsmetodes van projekte in Suid-Afrika tradisioneel is, aangesien dit nie toelaat vir vroeë betrokkenheid of vennootskappe binne die projekspan nie. Om vroeë betrokkenheid te verkry, is dit noodsaaklik om van ontwerp-en-bou, kontrakbestuur of publiek-privaat-vernootskappe gebruik te maak. Tans is daar geen hulp wat aan ontwerpers verleen word ten opsigte van besluitnemingsmodelle en ontwerpsagteware wanneer HBK oorweeg word in Suid-Afrika nie. Die behoefte aan sulke bystand dui daarop dat sagtewarepakkette ontwerp moet word wat toepaslik is vir Suid-Afrika se konstruksie-industrie. Die industrie bied nie doelgerigte en genoegsame opleidingsprogramme aan om die industrie se kennis van HBK te verbreed nie. Addisionele opleiding wat kognitiewe stimulasie sal bied vir die hele projekspan word aanbeveel. ’n Databasis wat HBK projekte insluit, moet geskep word om die industrie bloot te stel aan die verskillende moonlikhede. Arbeid-intensiewe konstruksie-regulasies asook groen konstruksietegnieke (nie wetgedrewe nie) word sterk bevorder in Suid-Afrika. Dit word hier aanbeveel, dat voorafvervaardiging se addisionele voordele in ag geneem word wanneer hierdie regulasies en tegnieke relevant is. Hierdie voordele sluit onder meer in: die veiligheid wat aan werkers gebied word in arbeid-intensiewe fabrieke en die vermindering van afval in HBK projekte. Afgesien van die land waarin HBK gebruik word, moet die omgewing ontvanklik vir die tegniek wees. Deur verskillende kriteria te analiseer wat die gebruik van HBK beïnvloed binne ’n land en geweegde faktore daaraan te koppel, kan die ontvanklikheid van die innovasie bepaal word. Laastens word publieke kliënte en maatskappye as die drywers (of katalisators) wat verandering kan meebring, beskou. HKB bied onder andere die volgende voordele aan publieke kliënte: koste-effektiwiteit, arbeid-intensiewe werk, groen konstruksie, beter gesondheid, veiligheid en opleiding vir werkers. Maatskappye kan gebruik maak van HBK om waarde tot hul projekte toe te voeg. ’n Model word hier voorgestel om innoverende maatskappye in staat te stel om nie net hulself nie, maar ook die industrie as ’n geheel te help om ’n gesindheidsverandering jeens HBK te skep.

Estratégias de flexibilidade na arquitetura residencial multifamiliar / Strategies of flexibility in the multifamily residential architecture

Jorge, Liziane de Oliveira 20 April 2012 (has links)
A arquitetura residencial coletiva, representada pelos edifícios multifamiliares voltados para as massas que habitam as áreas urbanas, é o maior protagonista da arquitetura cotidiana, desde o início do século XX, período que desenvolveu, propagou e consolidou o repertório formal, normativo e estético dessa célebre tipologia. As motivações que impulsionaram o desenvolvimento dessa nova forma de moradia coincidiram com uma enorme carência social e com a emergência por alojamentos, fato que assolou grande parte da população migrante que chegava às cidades, somadas às consequências das Grandes Guerras na Europa. A esses indivíduos, desorientados, restaram absorver as imposições da habitação coletiva - rígida, padronizada e uniforme - oferecida, muitas vezes, sob a égide do estado socialista, preocupado prioritariamente com aspectos quantitativos, dimensionais e higiênicos. Essa conjuntura moderna é escrutinada ao início do trabalho, bem como o papel da escola Vkutemas e do taylorismo como agentes de transformação da arte, da cultura e da sociedade do século XX. Apesar das incontestáveis contribuições à racionalização e à ciência da edificação, após um século, acredita-se que as mesmas regras, essencialmente modernas e universalizantes, ainda dominem a produção imobiliária atual: repetição idêntica de apartamentos tipo, preceitos funcionalistas, exigências mínimas relativas à habitabilidade, normas dimensionais padronizadas. Esses critérios, álibis perfeitos para uma arquitetura direcionada a usuários desconhecidos, disseminam, ainda hoje, modelos de caráter universal, reforçados por estratégias mercadológicas que homogeneízam o comportamento e pouco favorecem o uso diversificado do espaço da habitação, condição indispensável ao sujeito contemporâneo, ao estilo de vida plural das novas estruturas familiares, às rápidas transformações sociais, tecnológicas e culturais do mundo contemporâneo. Com o propósito de devolver ao morador tipificado um espaço doméstico de manifestação espontânea, imprevisível e natural, adequado às novas formas de vida, o trabalho investiga, ao longo do século XX, mecanismos de flexibilidade arquitetônica capazes de promover a adaptabilidade, a transformação e a particularização do espaço residencial, preceitos indispensáveis à satisfação do usuário e às diferentes necessidades ao longo do seu ciclo familiar. A sistematização de um amplo instrumental de flexibilidade é o produto primordial deste trabalho, capaz de nortear a concepção de novo projetos e a adequação de estruturas preexistentes, no intuito de promover, a partir da modificação de usos e da redefinição programática, novas respostas para o bem-estar físico e emocional dos usuários. / The collective residential architecture, represented by the multifamily buildings directed to people who live in the urban areas, has been the greatest protagonist of the everyday architecture since the beginning of the 20th century, period when has developed, expanded and consolidated the formal, normative and esthetic collection of this famous typology. The motivations that propelled the development of this new way of dwelling house coincided with an enormous social lacking and with the need for accommodations, fact that devastated a large part of the migrant population that reached the cities, in addition to the consequences of the Great Wars in Europe. To these disorientated individuals was left over to absorb the collective dwelling impositions - stiffness, standardized, uniform - offered sometimes as assistance from a socialist state, worried mainly with quantitative, hygienic and dimensional aspects. This modern conjuncture is scrutinized at the beginning of the work, as well the role of the \"Vkutemas\" school and of the taylorism as transformation agents of art, culture and of the 20th century society. In spite of the incontestable contributions to the rationalization and to the science of building, after a century, one believes that the same rules, essentially modern and universal, still dominate the current property production: identical repetition of type flats, functional concepts, minimal requirements for inhabitable conditions, standardized size norms. These criteria, perfect alibi for an architecture directed to unknown users, spread even today models of universal mark, reinforced by marketing strategies that homogenize the behavior and much little favour the diversified use of the housing space, which is an essential condition for the contemporary individual, for the plural life style of the new family structures, for the fast social, technological and cultural transformations of the contemporary world. With the objective to give the typified resident back a domestic space of spontaneous manifestation, unforeseeable and natural, adequated to the new ways of life, the work investigates, over the 20th century, mechanisms of architectural flexibility able to promote the adaptability, the transformation and the particularity of the residential space, precepts indispensable to the user satisfaction and to the different necessities along his family cycle. The systematization of a broad instrument of flexibility is the main product of this work, capable of leading the conception of new projects and the adaptation of pre-existing structures, in order to promote, from the modification of uses and from the programmatic redefinition, new answers for the physical and emotional well-being of the users.

Reflexe vývoje sousedství na panelovém sídlišti / Reflection on Neighbourhood Evolution at a Pre-Fabricated Panel Building Area

Pfaff, Tomáš January 2017 (has links)
The master's thesis, framed as a sociological case study, aims it's interest at the theme of neighborhood evolution at a pre-fabricated panel building area. The subject of interest is the reflection of neighborhood evolution given by the original residents of the research locality. The research locality is represented by the most populated street in Hradec Králové, Edvarda Beneše boulevard, which drew considerable attention both of lay and academic public at the time of it's emergence due to unique architectonic and urbanistic design. The defined research problem is the question asking about current state and underwent changes of a neighborhood situated at specific environment of a block-of- flats area located in a contemporary city, specifically in the most populated area of Hradec Králové statutory city. Also three separate research questions were formulated. They ask specifically about the current state of the neighborhood, it's underwent changes during time and the role of it's physical a geographical situatedness. The aim of the thesis was to perform complex exploration of current state and evolution of the studied phenomenon, both in social and physical dimension. The thesis doesn't provide description of the current state and evolution only, but it also identifies local relevant factors...
