    Abstract : A detailed understanding of natural photosynthesis provides inspiration for the development of sustainable and renewable energy sources, i.e. a technology that is capable of converting solar energy directly into chemical fuels. This concept is called artificial photosynthesis. READ MORE

  6. 4. Molecular Imaging of Diabetic Kidney Tissue and Binding Studies of Proinsulin C-peptide

    Author : Lina Lindfors; Jan Kihlberg; Ingela Lanekoff; Fredrik Almqvist; Uppsala universitet; []
