Nanoscopic Approaches in Earth and Planetary Sciences
The properties of matter at extreme length scales and the respective processes can differ markedly from the properties and processes at length scales directly accessible to human observation. This scale-dependent behaviour is possible in both directions; towards very large and very small scales. Scientists explore the frontiers of these extreme length scales in an effort to gain insight into yet unknown properties and processes. While the exploration of larger scales has been established since the Renaissance era, a comprehensive investigation of small scales was impeded by the limitations of optical microscopy. These imitations were overcome in the 20th century. Since then, a continuous series of developments in analytical power has taken place. Today these developments allow studies of properties and processes even at the molecular or atomic scale (often referred to as nanoscience). These modern nanoscientific possibilities have triggered new innovative projects in geosciences, providing fascinating insights into small scales. Therefore, nanogeoscience has become a very important geoscientific subdiscipline.
