13. ProduÃÃo de heterojunÃÃes de polianilina/silÃcio e nanofibras de polianilina para aplicaÃÃes em dispositivos hÃbridos
In this work we develop the methodology for the synthesis and fabrication of Polyaniline (PANI) â Silicon (Si) heterojunctions, with great potential for technological applications as sensors in different areas such as optics, ionizing radiation and gas detection. Besides, we were able to implement the electrospinnin technique with the goal of producing poly

14. Electrochemical behavior of Ti/Al2O3 interfaces produced by diffusion bonding
In the field of biomedical applications a special interest exists regarding the study of the physicochemical and mechanical behaviour of materials, with special focus on the electrochemical degradation of metal/ceramic interfaces. In fact, metal/ceramic interfaces may be present in several biomedical devices, ranging from external or implantable sensors, to

15. Integração de processos em tempo real para monitoramento e controle : aplicação para planta de PET
This work deals with the implementation of a soft-sensor for a PET (Polyethylene terephtalate) industrial process based on neural networks. The soft-sensor acts as redundant measure current for the polymer viscosity in the liquid phase; and, in case of mechanical faults, it is able to diagnoses the faults on the viscometer and can replace it.The viscosity co

16. Supramolecular chemistry and technology
Supramolecular chemistry deals with the association of several chemical species, in an organized way and according to well defined purposes. Based on a molecular engineering approach, supramolecular structures can be designed from pre-formed building blocks, providing a promising route from chemistry to molecular nanotechnology. New supramolecular systems ha

17. Interface gestual ultrassonica
The development of multimedia systems ensues the creation of man-machine interfaces that allow a more natural interaction. This paper describes a command input device able to recognize user gestures. Recognaissence is done by a user trained neural network, to fit specific working media needs. The device uses a handheld ultrasonic transmitter, steered to a se
