This study evaluated the effect of crystallization temperature (300, 500 and 700 °C) on the photocatalytic and photoluminescent properties of the multilayer thin films of TiO 2 , In 2 O 3 and TiO 2 /In 2 O 3 which were prepared by the Complex Polymerization Method (CPM) and deposited on substrates of Si (100) by the spin coating method. The results of X-ray diffraction (XRD) revealed that there was no chemical interaction between the oxides (TiO 2 /In 2 O 3 ) in crystalline films. The morphology was observed by atomic force microscopy (AFM) with a mean grain size of 15-35 nm. The result showed that the photocatalytic property is significantly increased by increasing the crystallization temperature. This is due to the agitation of the molecules which facilitates the transfer of charge between the electron and the catalyst bore. UV-vis light absorption spectra indicated that the addition of In 2 O 3 in TiO 2 films is an effective way of increasing the uptake of TiO 2 in the visible region up to ~ 600 nm for photocatalytic applications, it was also possible to observe that these films could be easily Recycled for reuse. The samples were also characterized by photoluminescence, where it was possible to observe that the reduction of the PL intensity increased the photocatalytic activity of the thin films, with the increase of the crystallization temperature. In addition, the method used in this study is simple and economical compared to other methods.

A hybrid approach for printing micro-wires on titanium substrate were presented.• The resistivity of the micro-wires was assessed via experimental and computational.• A comparative study between laser and anodizing for insulation layer was performed.• Laser technology was successfully used in additive and subtractive approaches.

RESUMO O presente trabalho analisa a decoração plástica dos fragmentos de vasilhas pertencentes à coleção cerâmica Itapiranga. Nosso objetivo é tentar identificar a individualidade da mulher indígena Guarani na confecção da cerâmica sem pintura.Buscamos prestar atenção nos gestos técnicos envolvidos na produção da cerâmica com decoração plástica, mais especificamente no corrugado e ungulado.Identificamosa presença de "padronizações" na produção docorrugado e doungulado e, também,elementos particulares, os quais não se repetem com frequência. Acreditamos que esses elementos particularestêm potencial para evidenciar a individualidade da mulher indígena, já que podem estar relacionadostanto com o grau de experiência da oleira na arte de confeccionar a cerâmica, quanto com a sua criatividade. Palavras-chave: Tradição Guarani; vasilhas; individualidade. ABSTRACT The present paper analises the plastic decoration of vessels sherds belonging to the Itapirangaceramic collection. Our aim resides in the identification of the individuality of Guarani women in the making of non painted pottery. In doing that, we pay attention to the technical gestures involved in the production of pottery with plastic decorations, more specifically on corrugated and ungulated ones. We identify the presence of "patterns" in the production of these decorations and, also, particular elements that not repeat so often. We believe that these particular elements have the potential to show the individuality of indigenous women, in the way that can be related to the experience degree of the potter as much its creativity.
