Harnessing the damping properties of materials for high-speed atomic force microscopy

Jürgen Brugger, Georg Fantner, Adrian Pascal Nievergelt, Jonas Grossenbacher, Blake William Erickson, Jonathan David Adams

The success of high-speed atomic force microscopy in imaging molecular motors1, enzymes2 and microbes3 in liquid environments suggests that the technique could be of significant value in a variety of areas of nanotechnology. However, the majority of atomic ...

Development of Implantable Electrodes Based on Polymer Derived Ceramics

Jonas Grossenbacher

The invention of heart pacemakers in the 50's aims to help patients to overcome heart strokes, which represent the first cause of death worldwide. In Europe and in the USA, more than 3000 pacemakers are implanted every day. Despite the constant evolution o ...
