1/f noise
Peter Hadley

Fluctuations in many systems such as traffic, avalanches, the stock market, or electronic devices often have a power spectral density that is often approximately inversely proportional to the frequency. This means that the low frequency components of the noise have a higher ampli ... more

Evaluating nanoscale contact and adhesion using FRET microscopy
Ulrich Hirn

Several intermolecular mechanisms are responsible for adhesion: hydrogen bonding, van der Waals forces and electrostatic interaction. Among these mechanisms hydrogen bonding and van der Waals attraction only work if molecular contact -- i.e. a distance between surfaces below a fe ... more

Extreme Ultraviolet Metaoptics
Marcus Ossiander

Extreme ultraviolet (EUV) light is a central component in ultrafast physics, materials science, and modern lithography. However, because all materials absorb EUV radiation, very few optics exist. I will describe the basics of a new approach for creating ultrathin optics: metasurf ... more

Crystallization of active pharmaceutical ingredients in thin films
Gabin Gbabode, University of Rouen

Utilizing surfaces for nucleation and growth is often adopted as a mean to enhance crystallization. Certain surfaces can accelerate crystallization while other prevent it. On the other hand, constrains induced by the surface can trigger crystal growth on well-defined contact plan ... more
