1. Drawing Electrochemical Sensors Using a 3D Printing Pen
This communication demonstrates that a 3D printing pen, commercially-available as a toy for kids, can be used to draw thermoplastic electrochemical sensors using conductive filaments over any desirable format and substrate. A polylactic acid filament containing graphene or carbon black was passed through the 3D pen that works as a handheld 3D printer (fused

2. The influence of heat treatment on the quality of screen printed textile substrates
ABSTRACT During exploitation, textile products printed with screen printing technique are quite often exposed to various influences, one of which is a heat treatment- firstly during the production process and later on when ironing. Heat is simultaneously affecting deposited colorants (ink) on the surface of the substrate material, as well as textile fibers i

3. Washing treatment impact on print quality of screen printed knitted fabrics
ABSTRACT The surface of textile materials is highly textured, commonly in non-uniform ways. Because of this texture effect, textile surface appears rougher and more porous than other printing substrates, which can cause excessive ink penetration during printing process. Next, washing process is very important factor because it influences ink characteristics

4. Análise de filmes antirreflexo de dióxido de titânio e nitreto de silício em células solares P+NN+
In this work we compared the antireflection coatings of titanium dioxide and silicon nitride for p+nn+ solar cell fabrication. This type of solar cell is more stable in the long term compared to n+pp+ cells and allows obtaining higher efficiencies. TiO2 films were produced by evaporation in high vacuum by electron beam and by chemical vapor deposition at atm

6. ObtenÃÃo, caracterizaÃÃo e aplicaÃÃo de uma nova superfÃcie Seletiva para coletores solares tÃrmicos / Acquisition, Characterization and Application of a New Selective Surface for Solar Thermal Collectors
O estudo de superfÃcies seletivas para coletores solares tÃrmicos, hà alguns anos, enfoca o uso de pastas e tintas para recobrir chapas de cobre ou alumÃnio, formando a placa absorvedora do coletor. Essas tintas ou pastas sÃo eletrodepositadas em placas metÃlicas, sendo este processo muitas vezes responsÃvel pelo levado custo de superfÃcies seletivas

8. MICROWAVE DEVICES USING HIGH DIELECTRIC CONSTANT FILMS / DISPOSITIVOS DE MICROONDAS UTILIZANDO FILMES DE ALTA CONSTANTE DIELÉTRICA
The growing demand for portable devices with more reduced size and weight has stimulated the search for materials with high dielectric constant and low losses in the microwave frequency range allowing circuit integration and miniaturization. In this work, a theoretical and experimental study of the use of high dielectric constant films in the fabrication of

9. Desenvolvimento de um biossensor para determinaÃÃo de triglicerÃdeos
Due to the necessity of more versatile methods for measure and accompany the lipid serum level, the production of several new analytical methods has been stimulated. This work shows a development of a monoenzymatic biosensor for triglycerides detection using Screen-printing technology, in which the reference electrodes (Ag/AgCl) and work electrode containing

10. Through the mirror: the constitution of negginer paiting of Andy Warhol (1956-1968) / Através do espelho: a constituição da pintura inicial de Andy Warhol (1956-1968)
Andy Warhol started to work with the silkscreen techniques in the 1960s. Graphic and photographic images were copied and transferred straight onto canvas. The artist abandoned the traditional modes of painting and began working with the appropriation of serialized images from billboards, photos, packages and film. The use of such clichés was controversial.

11. LITHOS EDIÇÕES DE ARTE AND THE TRANSITIONS OF USES OF THE TECHNIQUES OF REPRODUCTION OF IMAGES / A LITHOS EDIÇÕES DE ARTE E AS TRANSIÇÕES DE USO DAS TÉCNICAS DE REPRODUÇÃO DE IMAGENS
This dissertation analyzes the transitions of uses that the techniques of reproduction of images have passed through. The study identifies different functional outwardness assumed for such doings, and, among them, it privileges the specifically artistic approaches: those using techniques that lost their functional use and those that appropriate of techniques

12. Electrical properties of CdS/polyaniline heterojunction
Conducting polyaniline (PANI) has been synthesized using Sol-gel technique with chemical oxidation process. Chemically prepared cadmium sulphide has been printed on pellet of conducting polyaniline using screen-printing technique. I-V characteristics of conducting polyaniline and CdS printed conducting polyaniline have been recorded at room temperature using
