There is no such thing as "the" Max Planck Institute. In fact, the Max Planck Society operates a number of research institutions in Germany as well as abroad. These Max Planck Institutes are independent and autonomous in the selection and conduct of their research pursuits. To this end, they have their own, internally managed budgets, which can be supplemented by third party project funds. The quality of the research carried out at the institutes must meet the Max Planck Society's excellence criteria. To ensure that this is the case, the institutes' research activities undergo regular quality reviews.
The Max Planck Institutes carry out basic research in the life sciences, natural sciences and the social and human sciences. It is thus almost impossible to allocate an individual institute to one single research field: conversely, it can be the case that different Max Planck Institutes carry out research in the same subject.
Semiconductor chips and neuronal systems can be electrically coupled on a microscopic level. This research provides the fundament for an application of such hybrid processors in brain research, neuroprosthetics and information technology. On the neuronal side, ion channels, nerve cells and brain tissue are employed. On the electronic side, simple silicon chips with transistors and capacitors are used for the elucidation of the coupling mechanism. On that basis, complex chips are developed with more that 30000 contact sites to supervise neuronal activity with highest spatial resolution.
Modern X-ray diffraction techniques using microbeam radiation from synchrotron sources allow the imaging of the hierarchical structure of biological materials on different length scales. Moreover, in-situ X-ray diffraction provides the possibility to follow nanostructural changes of materials as a consequence of external influences such as mechanical deformation or humidity changes. This article presents a novel scientific instrument developed by the Max Planck Society at the BESSY storage ring in Berlin, which permits such experiments to be conducted with high resolution.
How do we recognize objects? How do we interpret facial expressions? Can we teach computers to see and understand? In this article, we present several research areas of the department "Human Perception, Cognition and Action" of the Max Planck Institute for Biological Cybernetics. The department employs methods from computer vision, computer graphics, and psychophysics in order to understand fundamental processes in perception and cognition.
In modern materials design there is an increasing demand for powerful computational tools that allow an accurate prediction of materials properties. The free energy of individual crystal structures serves as a key quantity in this context. The present paper discusses the capabilities of modern quantum-mechanical simulation methods in determining these energies. Since it is further demonstrated that even complicated phase transformation sequences can be predicted, these methods open new perspectives for the development and optimization of innovative, tailored materials.
Synchrotron radiation developed in the last decades to be an important tool for materials science. Its capability to resolve atomic-scale structures even of low-dimensional objects is very beneficial for corrosion science. Also the possibility of in-situ experiments is an advantage. With recent results on the dealloying of a binary noble metal alloy and Zn electrodeposition from ionic liquids, two examples are given.
