Wireless communication employing radio-frequency identification (RFID) tags is progressively more widespread in a variety of industrial and commercial sectors. Aspects as demanding specific needs regarding reading distance, ...

A busca por novos materiais é um dos grandes desafios da eletrônica que utiliza compósitos de materiais orgânicos e inorgânicos na produção de dispositivos eletrônicos. O interesse por esses materiais é devido a possibilidade ...

A novel, cheap, reliable water based precursor ink has been used for the large scale production of amorphous cobalt sulfide (CoS) on fluorine doped tin oxide (FTO). The method uses a metal-organic complex of Co(II) and ...

Mira Schendel (1919-1988), an artist from Switzerland who lived in Brazil, produced in the 1960s about 2000 monotypes, prints made of inked surface with the possibility of only one print. The research proposal is the study ...

This work presents the fabrication of multiwall carbon nanotubes (MWCNTs), its purification and the development of transparent electrical conductors (CETS) using these nanotubes, to achieve these objectives, the work ...

We develop a novel device comprised of high optical transmittance thin films containing silver nanowires (AgNWs) in poly(methyl methacrylate) (PMMA) acting as heating elements. The electrothermal control of the AgNWs network ...

Nowadays Brazil is the second largest producer and consumer of ceramic tiles in the world. In the process of tile’s production, the decoration and glazing play a prominent role since they are responsible for technical and ...

The properties of aqueous suspensions of cellulose nanocrystals (CNC) and their casted films are revised. The bio-nanoparticles are briefly introduced, including modifications of the crystals and the suspending media. The ...

In this work a novel preparation method is proposed for the one step synthesis and thin-film deposition of cost effective counter electrodes for dye sensitized solar cells (DSSC). This method is fast and allows depositing ...
