1. Implantação iônica de baixa energia em polímero para desenvolvimento de camadas compósitas nanoestruturadas condutoras litografáveis. / Low energy ion implantation into polymers to develop conductive composite layers for lithography.
Electronics using polymers instead of silicon is a recent research area with promising economic perspectives. Polymer with metallic particles composites presents interesting electrical, magnetic and optical properties and they have been produced by a broad variety of techniques. Metal ion implantation using plasma is one of the used methods to obtain conduct

2. SÃntese, caracterizaÃÃo e aplicaÃÃo de polianilina obtida atravÃs de uma nova rota fotoquÃmica
In this work we present an alternative route to obtain polyanilin e silver composite (PANI/Ag). The method consists to use light of wavelength 254 nm and aqueous solution of silver nitrate (AgNO3) to promote the anilinium mono mer polymerization and the consequent silver ions reduction. The composite was characterized by microanalysis technique, X-ray diffra

3. Reciclagem de fios e cabos elétricos. / Recycling of wires and eletrical cables.
The electro-electronics industry follows increasing the amount of scraps annually generated. For this reason it is necessary to recycle, so that it prevents the waste of raw materials and not renovable natural resources. The majority of the electro-electronic products do not receive any treatment after use and is disposed in municipal landfills together with

4. Materiais para cátodos de baterias secundárias de lítio
In this work, cathodes employed in secondary lithium batteries are reviewed. These cathodes have great technologic and scientific importance, specifically, materials for cathodes as electronic conductor polymers (ECP), transition metal oxides (TMO) and nanocomposites of ECP/TMO. The use of a specific cathodic material is based in some intrinsic characteristi

5. Construction of and auto-balanced ac suceptometer and study of eletronic conductor polymers for magnetic susceptibility and magnetic resonance. / Construção de um Susceptômetro AC Autobalanceado e Estudo de Polímeros Condutores Eletrônicos por Susceptibilidade Magnética e Ressonância Magnética.
A mutual inductance bridge which may be used for automatic measurement of ac magnetic susceptibilities from 4 K to room temperature, at frequencies up to 1 kHz, is described. The susceptometer employs an alternative and new arrangement for the probe. The coil set is kept at room temperature and moves in such a way to place the sample in the center of each of

6. Desenvolvimento de um capacitor eletroquimico polimerico
Conducting polymers represent an interesting class of materiaIs for using in electrochemical devices. These materials have important characteristics such as; changing from no conductor electronic state to conductor electronic state by redox process and changing of coloration by the application of an extern potential (electrochromism). The utilization of cond
