1. Study of electrophoretic deposition of ZnO photoanodes on fluorine-doped tin oxide (FTO) glass for dye-sensitized solar cells (DSSCs)
Abstract Semiconductors, such as zinc oxide (ZnO), are used in different scientific fields, including energy. This study applied ZnO thin films on a photovoltaic cell, specifically a dye-sensitized solar cell (DSSC). ZnO was used in solar cells due to its characteristics such as electronic mobility. Electrophoretic deposition (EPD) is an efficient method to

2. Minimizing the stroin energy of thin films on thick substrates / Minimização da energia de deformação de filmes finos com substratos espessos
O objetivo deste trabalho é a obtenção de um modelo tridimensional, que descreva as tensões que surgem em filmes finos depositados em substratos espessos planos. Para isto é utilizado o método da minimização da energia de deformação da amostra (filme fino/substrato), já descrito e utilizado na literatura para uma descrição unidimensional do prob

3. Characterization of thin titanium oxite films for ISFET application / Caracterização de filmes finos de oxido de titanio obtidos atraves de RTP par aplicação em ISFETs
This work presents the characterization of thin titanium oxide films as potential dielectric to be applied in ion sensitive field effect transistors. The films were obtained through rapid thermal oxidation and annealing of titanium thin films of different thicknesses deposited by Ebeam evaporation on silicon wafers. These films were analyzed by Ellipsometry,

4. Estudo da interaÃÃo entre compostos orgÃnicos volÃteis e filme finos de polipirrol
Conducting polymers can be used as active materials of sensing devices that find application in different areas, such as quality control of products in industries such as food and beverage, cosmetics and solvents, in the monitoring of air quality for environmental and safety purposes, and as an auxiliary tool in the diagnosis of diseases. In spite of this, a

5. A thermal surface phenomenon in the rabbit lung: possible basis for the conversion of heat into work.
1. Surfactant and fluid expressed from rabbit lungs has been used to form films on a simple Maxwell frame having a ratio of area-to-thermal capacity comparable to that existing in vivo. 2. When the area was increased by 2:1, the temperature fell by 5.6 degrees C and returned to 37 degrees C upon contraction as recorded by an infra-red thermometer with no the
