We investigated propagation of light through a uniaxial photonic metamaterial composed of three-dimensional gold helices arranged on a two-dimensional square lattice. These nanostructures are fabricated via an approach based on direct laser writing into a positive-tone photoresist followed by electrochemical deposition of gold. For propagation of light… (More)
This paper presents cell culture substrates in the form of microcontainer arrays with overlaid surface topographies, and a technology for their fabrication. The new fabrication technology is based on microscale thermoforming of thin polymer films whose surfaces are topographically prepatterned on a micro- or nanoscale. For microthermoforming, we apply a new… (More)
KIT's Executive Board has decided to discontinue the operation of the synchrotron radiation facility ANKA within category LK-II (user facility) of the Helmholtz Association and continue operation in LK-I (research). The KIT Senate confirmed this decision. Some aspects of the background and the rationale leading to this change are explained.
