The proposed ITN BIOENERGY deals with the understanding of experimental limits and fundamental principles for exploiting and developing electro-conducting nanoarchitectures to assemble highly efficient bioelectrocatalytic structures as a basis for efficient and stable biofuel cells. Based on that fundamental understanding, the main technological objective of BIOENERGY is to develop efficient and stable biofuel cells including potentially implantable biodevices. Individual elements like electrodes, enzymes and mediators will be developed, integrated into each other and finally assembled to bio fuel cells. ESR and ER will be work on the all tasks of this scientific chain being therefore trained in the fundamentals of bioelectrochemistry, modern experimental methods in bioelectrochemistry and applications of bioelectrochemistry. Training of the fellows will take place at the host institute, via secondments, workshops, summer schools and joint measurement campaigns. The scientific training will be completed by training of complementary skill with respect management, fund raising and scientific communication.The consortium consists of the leading scientists in bioelectrochemistry in Europe and is supported by several private partners working in the field. It is expected that BIOENERGY will improve the availability of a highly skilled workforce for European industries and research, and will be the seed of innovative long-term research and education in bioelectrochemistry.
