Abstract:
La expresión “literatura de cordel” agrupa unívocamente a todo aquel tipo de papeles que eran vendidos en la calle expuestos a la atención del público colgando de una cuerda. La contemplación del pliego solía hacerse en la plaza o en un mercado y el editor solía buscar un efecto mostrando un grabado en la portada. Para conseguir que ese grabado atrajera sin dudar a quien se acercase al vendedor de pliegos, demandaba la colaboración de un artista plástico que trasladase a imágenes lo que de otro modo expresaban las palabras del autor del pliego y exigía a ese artista que las figuras –de animales o humanas- fuesen identificables, respetasen un deseable plano general y al mismo tiempo parecieran relativamente cercanas. El tratamiento dado por algunos de esos artistas a los temas de los pliegos llegó a hacerse tan peculiar que su forma creó un “estilo” y un repertorio con personalidad y estética propias. En este artículo se analizan algunos de los temas recurrentes que influyeron en la creación de una mentalidad común de largo recorrido.

Abstract:
Abstract Different friction mechanisms for coated board were investigated. Friction due to adhesive forces, interlocking of asperities and plastic deformation, respectively, was evaluated for coated board. The measurements of friction were combined with measurements of surface energy and measurements of gloss variations. The samples coated with only latex showed significant frictional forces but no signs of polishing or plastic deformation. Friction seemed here to depend on adhesive forces and a correlation could be observed between the surface energy and the coefficients of friction. Adhesive forces seemed to be of less importance for coatings with normal binder content. Increases in gloss variations indicated that friction was partly due to plastic deformation resulting from polishing. Samples calendered at room temperature showed clear signs of polishing while samples calendered at increased temperatures showed little or no polishing. These samples were probably too smooth on a particle level to create wear on each other during friction measurements. The base substrate, on the other hand, did not seem to have any influence on friction, and it was thus concluded that friction depended mostly on asperities on a particle size scale and plastic deformation due to polishing.

Abstract:
This is a trilogy of papers about land and people and the ecology they create together. Leah lives on the coast in South Wales. Lisen lives on the island of Gotland in Sweden. Gail lives in Yorkshire in the north of England. What connects us and our writings is the land, its history, its place in industry and what we do and don’t see. The cuts in the land reflect the cuts in our minds, unnegotiated edits in our stories, and disconnects in political discourses. This trilogy of papers documents some of these cuts and joins. We speak about the land we walk on and the stories told about it. We point to scars in the landscape and ask how they connect with those in the lungs and on the wrist. The landscape of the present holds clues about its past and its future. And the timescapes in the writings evoke a necessity to connect time and place, human and non-human colonising and liberatory methods and live with a maddening, flickering lenticularity (Pillow, 2019).

Abstract:
Often the setting of a novel can be looked at as a minor portion of a work. However, with Thomas Hardy’s Tess of the d’Urbervilles 1892 landscapes seem to be close to the main character, Tess. The story is about a teenage girl who experiences life in six different places; Marlott, Trantridge, Talbothays, Wellbridge, Flintcomb-Ash and Stonehenge. Each location shows a phase in her life and has a great impact on her in different ways. They allow the reader to understand her feeling and emotions at the time. This research examines Hardy’s use of setting and its reflection on the main character in order to show how the two are related together.

Abstract:
Como qualquer material fabricado a partir de fibras de madeira, o papel também apresenta variações dimensionais decorrentes de modificações no seu teor de umidade. O presente trabalho aborda o comportamento desta propriedade do papel, denominada higroexpansibilidade, medida em papel reprográfico fabricado a partir de fibras de eucalipto, durante o processo de produção em uma máquina industrial. O estudo foi realizado com amostras de papel de 75 g/m2, coletadas em diversos pontos de uma máquina comercial, operando à velocidade de 1256 m/min. No estudo, encontram-se dados de higroexpansibilidade medidos ao longo da máquina de papel, desde a seção de formação até o acabamento, e na direção transversal da folha na enroladeira. A análise dos resultados permite a verificação de influências das operações e tratamentos envolvidos na fabricação do papel (formação, prensagem, secagem e acabamento) sobre a sua higroexpansibilidade. Os resultados das medições desta propriedade são discutidos em termos de efeitos provenientes das condições operacionais estabelecidas para a fabricação do papel, permitindo reconhecer influências da orientação de fibras, do processo de secagem e da restrição ao encolhimento, da aplicação de amido superficial e da aplicação de tensões na direção longitudinal e transversal do papel. Para comparação e suporte à discussão de resultados, foram também medidas propriedades estruturais, de resistência e propriedades elásticas do papel. Na conclusão do trabalho, são apresentadas sugestões para controle e minimização da higroexpansibilidade do papel destinado ao uso final, com enfoque em ações a serem tomadas, no que se refere ao ajuste do processo de fabricação. Finalmente, apresentam-se comentários sobre futuros trabalhos que poderão ser desenvolvidos, a fim melhor entender fenômenos adicionais relacionados à higroexpansibilidade e buscar alternativas para seu controle, por se tratar de uma propriedade cada vez mais importante para os processos de impressão e operações de conversão, cujos efeitos podem limitar o desempenho e a utilização final do papel.
Like any material made from wood fibers, the paper also exhibits dimensional changes as a result of change in moisture content. This work deals with the behavior of this paper property, called hygroexpansivity, which was measured in reprographic paper manufactured from eucalyptus fibers, during the production process in an industrial paper machine. The study was developed using 75 g/m2 paper samples collect in different positions of a commercial paper machine running at the speed of 1256 m/min. In the study, data of hygroexpansivity measured along the paper machine can be found from the forming section up to the finishing section and from the cross machine direction at the reel. The analysis of the results reveals the effects of the operations and treatments involved in the papermaking (formation, pressing, drying and finishing) on the hygroexpansivity. The measurements results of this property are discussed with focus on the effects of the operating conditions established for the papermaking operation, what leads to the recognition of the effects of the fiber orientation, drying process, shrinkage restraint, starch sizing and tensions applied to the paper in machine direction and cross machine direction. For comparison purposes and result discussion support, some structural, strength and elastic paper properties were also measured. In the conclusion of the study, some suggestions for control and minimization of hygroexpansivity of the end use paper are presented, focusing on actions to be taken, which are related to the adjustment of papermaking process. Finally, comments referred to future work for better understanding of additional hygroexpansivity mechanisms are also mentioned, in order to suggest future investigation of control alternatives for this property, since it’s importance has been more and more highlighted in printing and conversion operations because, at times, it can limit the performance and usefulness of paper.

Resumo: Realizou-se primeiramente neste trabalho o estudo de um supercapacitor padrão utilizando coletores de aço inox e eletrodos de grafite Aquadag®. Este dispositivo apresentou uma capacitância máxima de 22 F/g, e seu espectro de impedância foi modelado por um circuito do tipo R(C(RW))(RC)(RC). Com este dispositivo foi possível testar os métodos de produção dos supercapacitores, e identificar as características desejáveis no supercapacitor impresso. Foram testadas duas técnicas de impressão distintas visando o preparo de eletrodos e coletores de corrente impressos em papel para aplicação em supercapacitores. O material ativo utilizado nos eletrodos foi basicamente o PEDOT:PSS, com a adição de óxido de grafeno, grafite aquadag® e nanotubos de carbono de paredes múltiplas (MWNT) para a formação compósitos condutores. Foram realizadas caracterizações morfológicas e elétricas nas superfícies dos eletrodos impressos em papel filtro, vegetal e sulfite. Os eletrodos produzidos por serigrafia utilizando o compósito de PEDOT:PSS com MWNT impressos em papel filtro apresentaram os menores resultados de resistência de folha (17 Ω/sqr), sendo assim utilizados na produção dos supercapacitores. O supercapacitor impresso em papel apresentou um bom comportamento capacitivo através de medidas de espectroscopia de impedância e voltametria cíclica. A curva de impedância foi modelada através de um circuito do tipo R(RC)(C(RQ))(RC), evidenciando uma alta capacitância de dupla camada. Foi encontrada uma...

Abstract: In this study, we first produced a standard supercapacitor using stainless steel collectors and Aquadag® graphite electrodes. The device exhibited a maximum capacitance of 22 F/g, and an R(C(RW))(RC)(RC) circuit modeled its impedance spectrum. With this device was possible to test the production methods of supercapacitors, and identify its desirable characteristics. Two different printing techniques were tested to produce electrodes/current collectors. The active material used in the electrodes was PEDOT: PSS, with addition of graphene oxide, Aquadag® graphite and multi-walled carbon nanotubes (MWNT), in order to obtain conductive composites. Morphological and electrical characterizations were performed over the surfaces of printed electrodes onto filter, vegetable and bond paper. The electrode produced by screen-printing using the PEDOT: PSS/MWNT composite printed onto filter paper exhibited low sheet resistance (17 Ω /sqr), being used in the production of supercapacitors. Printed supercapacitor showed good capacitive behavior through impedance spectroscopy and cyclic voltammetry measurements. An R(RC)(C(RQ)(RC) circuit modeled the impedance spectrum, evidencing a high double layer capacitance. A maximum specific capacitance of 20.3 F / g was found for a charge/discharge current of 1 mA, and an equivalent series resistance of 60 Ω. These values led to energy and power densities of 3.1 Wh / kg and 420 W / kg, respectively. Simulations and curve fitting were also performed fro... (Complete abstract click electronic access below)

Resumo: Neste presente trabalho, foi estudada a grafitização de N-metilol acrilamida em amido de mandioca nativo, em meio aquoso, com proporções de 20, 30 e 40% em relação ao peso de amido, tendo como objetivo avaliar a aplicação técnica do produto resultante em formulações de tintas de revestimentos couché, aplicado sobre uma superficie de papel cartão. Estes novos polímeros, bem como o amido de mandioca e o amido de milho nativo, foram caracterizados por: (i) Análise Dinâmico-Mecânica (DMA), onde se conseguiu verificar moderadas modificações nas transições térmicas; (ii) Espectroscopia na região do Infravermelho(FT_IR); (iii) Microscopia Ótica (MO) e (iv) Microscopia Eletrônica de Varredura (MEV), onde percebeu-se mudanças morfológicas nos grânulos de amido modificado, que se apresentaram maiores que os do amido nativo. Para uma análise do comportamento destes polímeros em formulações de tintas de revestimentos couché, foi utilizado como referência padrão o látex de estireno-butadieno carboxilado, atualmente utilizado na indústria de papel, como ligante (ou resina) principal. Nas tintas de revestimentos couché desta tese, foram analisadas as aplicações feitas em papel cartão revestido, onde se utilizou para teste de imprimibilidade as seguintes análises: Pick teste seco; Pick teste úmido; alvura; teste de absorção superficial - K & N; brilho de impressão; rugosidade e absorção de óleo. Um bom revestimento deverá apresentar uma boa adesão à superficie do papel, evitando seu arrancamento do mesmo. Dos testes de arrancamento, todas as amostras dos revestimentos feitos com amido de mandioca, modificados com Nmetilol acrilamida, apresentaram excelentes resultados
Abstract: In this work, it was studied the graftization of native tapioca starch with of Nmethylol acrylamide (NMA) in aqueous media, at several proportions (20, 30 e 40%) relative to the starch weight, with the aim to evaluate the technical application of the product obtained in inks formulations used for finishing covering, applied over paper-card surfaces. The NMA and the native starch, as well as the starch derivatives, were characterized by: (i) Dynamic Mechanical Analysis (DMA), which showed mild modifications in the thermal transitions; (ii) lnfrared Spectroscopy (F_TIR); (iii) Oplical Microscopy (OM) and (iv) Electron Scanning Microscopy (SEM) which revealed morphological changes in the starch grains, being the modified starch grains bigger than those native. To analyze the behavior of these polymers in formulations of inks, used for finishing covering (known as couché paper card), it was utilized latex of styrene-butadiene - carboxylate as reference, current1yused as binder in the paper industry. For the paper card with the finishing covering it was utilized tests of printability as: dry pick test; wet pick test; whiteness; K and N test; shine of impression; roughness and oil absorption. In the printing process, the graphic ink used presents tacking that is responsible for a perpendicular force to the surface of the paper, which is able to peel its covering. The peeling tests done with the formulations modified with modified tapioca starch with Nmethylol acrylamide (NMA) presented very promising results

Abstract:
Nordic Paper Åmotfors tillverkar elektrotekniskt papper som används till att isolera lindningarna i transformatorer. Det är viktigt att bibehålla papprets egenskaper under en mycket lång tid då en transformators livlängd är lång. Syftet med detta examensarbete var att undersöka huruvida tillsats av en kemikalie bestående av dicyandiamid kan fördröja åldrandet av de papper som Nordic Paper tillverkar. Förhoppningen var att deras papper därefter skulle klara de krav-parametrar som finns för papper som åldrats i olja. Kemikalien som användes var Cartafix® WE liquid. Försök utfördes där olika kemikaliedoseringar tillsattes i mälden. Pappersark tillverkades och kvävehalten mättes därefter för att verifiera att kemikalien fastnat i de färdiga papprena. Pappers-arken åldrades sedan endera i olja eller i luft, och den kvarvarande polymerisationsgraden (DP) mättes. Sprängstyrke- och konduktivitetstester utfördes också. Papper som Nordic Paper tillverkat beströks med olika kemikaliedoseringar och samma tester utfördes även på dessa. Resultaten visade att retentionen av kemikalien var låg. Kvävehalten blev inte högre än 1 % och detta skedde vid 10-20 % kemikalietillsats. Efter åldring i olja minskade DP relativt mycket, vilket medförde att papprena inte uppnådde de uppsatta kraven (maximalt 50 % minskning). Tillsats av kemikalien förbättrade dock papprets åldringsegenskaper med nästan 45 % om icke-modifierat papper jämförs med det modifierade pappret som hade högst DP (10 % kemikalietillsats, vilket motsvarade 1 % kvävehalt). Papper som modifierats med kemikalietillsats i mälden gav lägre DP då åldringen skett i luft jämfört med icke-modifierat papper. DP minskade avsevärt efter åldring för papper som bestrukits med kemikalien. Kemikalietillsats försämrade både sprängstyrkan och konduktivteten.
Nordic Paper Åmotfors manufactures electro technical paper that is used to isolate the windings in transformers. It is important to maintain the properties of the paper during a long period of time because the life of a transformer is extensive. The purpose of this thesis was to investigate whether or not addition by a chemical consisting of dicyandiamide could delay the ageing of the papers that Nordic Paper manufactures. The aspiration was that their paper would then fulfil the requirements that are applicable to papers that have been aged in oil. The chemical that was utilised is called Cartafix® WE liquid. Experiments were conducted where different dosages of the chemical were added to the stock. Sheets of paper were manufactured and the nitrogen level was then measured in order to verify that the chemical had been fused in the finished paper. The paper sheets were then aged in either oil or air and the remaining degree of polymerisation was measured. Bursting strength and conductivity were also evaluated. Papers that Nordic Paper had manufactured were coated with different dosages of the chemical and then investigated in the same manner. The results showed that the retention of the chemical was relatively low. The nitrogen level did not exceed 1 %, which occurred at 10-20 % addition of the chemical. After ageing in oil, the degree of polymerisation was significantly reduced, which meant that the papers did not fulfil the requirement of a maximum of 50 % reduction. The addition of the chemical did however improve the ageing resistance with nearly 45 % if the unmodified paper is compared to the modified paper with the highest degree of polymerisation (10 % addition, equivalent to 1 % nitrogen). Papers that had been modified by addition of chemicals in the stock and had been aged in air exhibited lower degree of polymerisation than unmodified paper. The degree of polymerisation was significantly reduced for papers that had been coated and aged in air. Addition of chemicals resulted in both lower bursting strength and lower conductivity.

Abstract:
Solar energy has a great potential to give cheap and abundant energy to rural areas of the world, but is the technology ready to be implemented today? This stydy looked at the possibilities to introduce more renewable energy into the local hand-made paper production in Bangladesh. Specifically the potential of solar heated vacuum tubes filled with water as a heat carrier. This type of solar thermal collectors are cheap to produce, relatively efficient at converting both direct and diffuse solar energy into usable energy, and have a very simple construction that do not require a lot of training to handle. The study showed that the collector could convert about 70 % of the energy from the sun into usable energy in the form of hot water circulated in the system. On average in Bangladesh the 5 m2 collector used is expected to have an output of about 25.6 MJ per day (yearly average) and about 4.8 MJ was needed to evaporate 1 kg of water from the drying papers (including the system losses). This can be compared with the old system that used about 8 MJ per kg water evaporated. Finally the study includes a step by step guide into how to build a system like this by locally available material. The only parts that were imported were some measurement equipment and parts of the collector that was not yet available through local distributors. The pump was also not produced in Bangladesh, but a similar pump could be bought by local companies that import this type of equipment.

Abstract:
Le papier est un matériau très commun que l'on manipule quotidiennement. Pourtant on ne le trouve que rarement dans les environnements 3d. En effet, à cause de sa structure fibreuse, le papier, de même que le son qu'il produit, présente un comportement complexe qui se révèle difficile à reproduire avec les méthodes habituelles. En particulier, la surface du papier reste constamment isométrique à son patron 2D et peut se froisser ou se déchirer, créant ainsi de fins détails géométriques. Lorsqu’il se déforme, le papier produit également un son très caractéristique qui dépend fortement de la géométrie adoptée par la surface.Dans cette thèse, nous proposons de combiner une simulation physique usuelle avec de nouvelles méthodes, procédurales ou géométriques, de façon à tirer parti de connaissances préalables afin de modéliser la surface et le son d'une feuille de papier manipulée virtuellement. Plutôt que d'obtenir des résultats précis au sens physique, nous cherchons à reproduire un comportement plausible du papier, permettant ainsi à un utilisateur de créer interactivement des animations de papier virtuel.Nous nous concentrons dans un premier temps sur le cas du papier froissé. Pour cela, nous entrelaçons une étape de simulation physique avec une étape de remaillage géométrique qui adapte le maillage aux plis du papier froissé, exploitant pour cela la dévelopabilité du papier.Nous tirons ensuite profit de ce modèle pour développer une méthode permettant de déchirer du papier virtuelle en temps réel. Nous utilisons les informations sur la géométrie fournie par l'étape de remaillage pour trouver les points pouvant potentiellement être les points de départ d'une déchirure. Nous proposons aussi une nouvelle approche hybride, à la fois physique et géométrique, pour déterminer la direction général de propagation tout en créant de façon procédurale les détails du tracé d'une déchirure en utilisant une texture représentant la répartition des fibres.Enfin, nous proposons une génération de sons de papier, à la fois plausible, dépendant de la forme de la surface et qui s'opère en temps réel. Nous analysons les informations, géométriques et dynamiques, données par le modèle d'animation pour détecter les événements produisant du son et calculer les régions dans lesquelles le son résonne. Le son résultant est synthétisé à l'aide de sons pré-enregistrés et d'une génération procédurale, de façon à tenir compte de géométrie de la surface et sa dynamique
Although paper is a very common material in our every-day life, it can hardly be found in 3d virtual environments. Indeed, due to its fibrous structure, paper material exhibits complex deformations and sound behaviour which are hard to reproduce efficiently using standard methods. Most notably, the deforming surface of a sheet of paper paper is constantly isometric to its 2D pattern, and may be crumpled or torn leading to sharp and fine geometrical features. During deformation, paper material also has very characteristic sound, which highly depends on its complex shape.In this thesis, we propose to combine usual physics-based simulation with new procedural, geometric methods in order to take advantage of prior knowledge to efficiently model the geometry and the sound of a deforming sheet of paper. Our goals are to reproduce a plausible behaviour of paper rather than an entirely physically accurate in order to enable a user to interactively deform and create animation of virtual paper.We first focus on the case of paper being crumpled. We use the developability property of the paper to interleave the physics-based simulation with a geometric remeshing step that adapts the mesh with the fold and the sharp creases of crumpling paper. We obtain an interactive model able to reproduce the main features of crumpling paper.We then take advantages of this model to develop of method for tearing paper in real-time. We use the geometric information provided by the remeshing step of the model to detect potential starting points of tears, and propose a new hybrid, geometric and physical, method to find their general direction of propagation while creating procedurally the details of the tearing path using a fibres' texture.Finally, we propose to generate a plausible shape-dependant sound of the paper at run-time. We analyse the geometric and dynamic information provided by the model to detect sound-producing events and compute the regions in which the sound resonate. The resulting sound is synthesized from both pre-recorded sounds and procedural generation taking into account the geometry of the surface and its dynamics

Abstract:
Os novos processos de impressão têm exigido novas características do papel. Entre os novos processos encontram-se as impressões digitais, em especial, a impressão por jato de tinta. Este tipo de impressão é baseado na ejeção de uma gota de tinta por um orifício em uma cabeça de impressão, que atinge o substrato formando um pixel. A definição das imagens formadas neste tipo de impressão é, portanto, dependente das características da tinta e, principalmente, do substrato. O presente trabalho tem por objetivo caracterizar as propriedades do papel que são importantes para a impressão por jato de tinta, desde o momento em que a tinta atinge a superfície do papel até a sua absorção. As propriedades consideradas neste estudo foram: a rugosidade, a porosidade e as propriedades químicas da superfície. A rugosidade foi avaliada pelos métodos tradicionais da área de papel e celulose (baseados em vazão de ar), por método perfilométrico e, qualitativamente, por imagens obtidas por microscopia eletrônica de varredura (MEV). Para a porosidade foi utilizado um método tradicional, além de porosimetria de intrusão de mercúrio e microtomografia de raios X, e a composição química da superfície foi avaliada por espectroscopia por energia dispersiva (EDS) e espectroscopia Raman. A partir dos resultados obtidos, as propriedades do papel foram qualificadas e as suas influências no espalhamento e absorção de líquidos em geral foram identificadas. Além da caracterização das propriedades superficiais e porosimétricas do papel, as correlações entre as propriedades e os diferentes métodos utilizados na sua determinação foram discutidas. Os métodos de análise tradicional não conseguem caracterizar os papéis em níveis de resolução capazes de fornecer informações sobre a influência das propriedades estudadas na impressão por jato de tinta. Ao mesmo tempo, a caracterização do papel para este tipo de impressão e a compreensão das influências das propriedades do papel no espalhamento e absorção de tinta e líquidos em geral só é possível quando as propriedades são analisadas em conjunto.
The new printing processes have required new features of the paper. Among the new printing processes are the digital printing, in particular, the inkjet printing. This type of printing is based on the ejection of an ink drop through a hole in a print head, which reaches the substrate forming a pixel. The resolution of the images formed in this type of printing is therefore dependent on the characteristics of the ink, and especially of the substrate. The present work aims to characterize the properties of paper that are important to the inkjet printing, from the moment the ink hits the paper surface to its absorption. The properties considered in this study were: roughness, porosity and chemical properties of the surface. The roughness was evaluated by traditional methods in pulp and paper sector (based on air flow), by profilometry and qualitative using images obtained by scanning electron microscopy (SEM). For the porosity, a traditional method was used, and also mercury intrusion porosimetry and X-ray microtomography. The chemical composition of the surface was evaluated by energy dispersive spectroscopy (EDS) and Raman spectroscopy. From the results obtained, the paper properties were described and their influence on the spreading and absorption of liquids in general have been identified. Besides the characterization of the paper surface properties and porosity, the correlations between the properties and the different methods used for measurement were discussed. The traditional analysis methods can not characterize the paper in levels of resolution capable of providing information about the influence of the properties studied in inkjet printing. At the same time, to characterize paper for this printing process and to understand the influences of the paper properties on the spreading and absorption of inks and liquids in general the paper properties have to be analyzed together.

Resumo: Neste trabalho descreve-se a construção e aplicação de dispositivos analíticos 2D e 3D à base de papel com detecção eletroquímica (ePAD). Os dispositivos foram construídos empregando o método de impressão com cera e diferentes tipos de papéis. Eletrodos de ouro foram utilizados juntamente com o conceito da separação cromatográfica em dispositivos microfluídicos. No canal microfluídico à base de papel foi possível realizar a separação de ácido ascórbico e dopamina em 14 minutos. A necessidade por processos de fabricação mais simples e de baixo custo nos motivou a estudar eletrodos de carbono em ePADs. Assim, eletrodos de grafite de lapiseira foram selecionados visando o desenvolvimento de um biossensor para glicose. O biossensor apresentou uma excelente resposta eletroquímica e um tempo de análise de 4 minutos. O mesmo eletrodo de grafite foi acoplado com um sistema de informação para determinação de p-nitrofenol. Assim, foi possível detectar 1,0 mmol L de p-nitrofenol em amostras de água e analisar/interpretar os resultados empregando um celular. Por fim, a necessidade por sistemas eletroquímicos com menores limites de detecção nos impulsionou a fabricar microeletrodos de pasta de carbono. Os microeletrodos foram fabricados em folhas de transparência e acoplados no papel empregando uma configuração do tipo sanduíche. Os dispositivos foram caracterizados eletroquimicamente na presença de cisteína e apresentaram uma constante cinética de 10 L mol s. Um limite de detecção de 4,8 mmol L para cisteína foi obtido empregando um arranjo de microeletrodos. Por fim, os microeletrodos de pasta de carbono foram utilizados para a construção de um biossensor visando a determinação de metil paration. O ePAD foi construído de modo a acomodar o substrato (acetiltiocolina) e a enzima (acetilcolinesterase) no mesmo dispositivo
Abstract: This thesis describes the construction and application of 2D and 3D electrochemical paper-based analytical devices (ePADs). The devices were constructed using the wax printing method and different types of papers. Gold electrodes were employed along with the concept of chromatographic separation in microfluidic devices. By using the paper-based microfluidic channel it was possible to perform the separation of ascorbic acid and dopamine in 14 minutes. The need for simpler and low cost manufacturing processes motivated us to study carbon electrodes in ePADs. Thus, pencil graphite electrodes were selected for the development of a biosensor for glucose. The biosensor exhibited excellent electrochemical response and analysis time of 4 minutes. The same graphite electrode was coupled to an information system for the determination of p-nitrophenol. Thus, it was possible to detect 1.0 mmol L of p-nitrophenol in water samples and analyze/interpret the results using a smartphone. Finally, the need for electrochemical systems with lower limits of detection made us to search for carbon paste microelectrodes. The microelectrodes were fabricated on transparency sheets and coupled on paper using a sandwich-type configuration. The devices were characterized electrochemically in the presence of cysteine and had a rate constant of 10 L mol s. A detection limit of 4.8 mmol L for cysteine was obtained using an array of microelectrodes. By last, carbon paste microelectrodes were used to construct a biosensor in order to determine methyl parathion. The ePAD was constructed to accommodate the substrate (acetylthiocholine ) and enzyme ( acetylcholinesterase ) in the same device
