Journal ArticleDOI
The salvinia paradox: superhydrophobic surfaces with hydrophilic pins for air retention under water.
Wilhelm Barthlott,Thomas Schimmel,Sabine Wiersch,Kerstin Koch,Martin Brede,Matthias Barczewski,Stefan Walheim,Aaron Weis,Anke Kaltenmaier,Alfred Leder,Holger F. Bohn +10 more
TL;DR: [*] Prof. W. Barthlott, S. Schimmel, Dr. S. Walheim, A. Weis and M. Barczewski study the construction of nanostructures using nanofiltration membranes for the recovery of phosphorous content in response to the presence of non-volatile materials.
Journal ArticleDOI

Argishti Melikyan,Nicole Lindenmann,Stefan Walheim,Philipp M. Leufke,Sven Ulrich,J. Ye,P. Vincze,Horst Hahn,Th. Schimmel,Christian Koos,Wolfgang Freude,Juerg Leuthold +11 more
TL;DR: A new compact electrically controlled surface plasmon polariton (SPP) absorption modulator operating at communication wavelengths is introduced.
Journal ArticleDOI
On the dielectric and optical properties of surface-anchored metal-organic frameworks: A study on epitaxially grown thin films
TL;DR: In this paper, the optical constants of two highly porous, crystalline metal-organic frameworks (SURMOFs) were determined using spectroscopic ellipsometry (SE).
Journal ArticleDOI

TL;DR: It is shown that lyotropic optical diffraction gratings--composed of biofunctional lipid multilayers with controllable heights between approximately 5 and 100 nm--can be fabricated by lipid dip-pen nanolithography, allowing nanostructures to be interfaced by combinations of top-down and bottom-up fabrication methods.
Journal ArticleDOI
In situ monitoring the drying kinetics of knife coated polymer-fullerene films for organic solar cells
Benjamin Schmidt-Hansberg,Michael F. G. Klein,K. Peters,F. Buss,J. Pfeifer,Stefan Walheim,Alexander Colsmann,Uli Lemmer,Philip Scharfer,Wilhelm Schabel +9 more
TL;DR: In this paper, a comparative study using atomic force microscopy (AFM) and optical in situthin film drying measurements is performed to understand the film formation kinetics and prerequisites for the systematic optimization of the film morphology in solution processed organic photovoltaic devices.
