Forschungszentrum Jülich - Annual Report 2012

March 2012 to March 2013 Chronology Printing Bioelectronic Chips 21 March 2012 | The journal Advanced Functional Materials publishes a paper by scientists from Forschungszentrum Jülich and Sony Deutschland GmbH that makes it to the front page. The researchers present a method to cheaply and easily produce electronic circuits with sensitive polymers or biological molecules. The procedure involves a skilful combination of nanoimprint and stamping technologies that only require the biomolecules to withstand room tempera- ture and normal pressure. Insight into the Formation of Plaques 20 April 2012 | Diseases such as Alzheimer’s and Creutzfeldt- Jakob involve a striking amount of deposits of clumped protein in the brain, referred to as amyloid plaques by experts. In the journal Science, an international team headed by Jülich scientist Philipp Neudecker reports that they have observed an important intermediate stage in the formation of these plaques with the help of NMR spectroscopy. This incorrectly folded protein state only exists for a few thousandths of a second (see ‘Faulty Folding – Catastrophic Consequences’ on p. 30). Electrochemistry on the Atomic Level 29 April 2012 | In the journal Nature Materials, researchers from the Jülich Aachen Research Alliance (JARA) and Japanese colleagues present a new method for investigating electrochemical metallization memory cells (ECMs) on the atomic level. ECMs could potentially succeed today’s computer memory technology because, in principle, they are able to switch in a faster and more energy-efficient manner. 8 Forschungszentrum Jülich | Annual Report 2012
