IMPACTS CAUSED BY THE ACTIONS AND RESULTS OF THE PROJECTC TECHNOLOGICAL TRANSFER: We are in the beginning of projects withtwo companies Electronics in papers (Suzano) and Flexible Electronics (CSEM).D SCIENTIFIC DIVULGATION: INEO is one of the Sponsors of theCinciaWEB (used to divulgation of Science) whose site is:http://143.107.180.237/iea/index.php/news_site/). Other programs are:1- Workshop for teachers of primary and high schools;2- Experimenting with Physics;3 - De Cara com Feras (Facing the VIS)E - MINI-COURSES:With the courses and exchange, the knowledge on the part of the students aboutOrganic Electronics has been expanded fast. 69.
