Immobilization of water drops on hydrophobic surfaces by contact line pinning at non-lithographically generated polymer microfiber rings
Peilong Hou, Martin Steinhart
Water drops used as reaction compartments are commonly immobilized on hydrophilic areas bordered by hydrophobic areas. For many applications, such as the trapping of non-adherent c…
Free-sustaining Three-dimensional S235 Steel-based Porous Electrocatalyst for Highly Efficient and Durable Oxygen Evolution
Weijia Han, Karsten Küpper, Peilong Hou +5
A novel oxygen evolution reaction (OER) catalyst (3D S235-P steel) based on steel S235 substrate has been successfully prepared via a facile one-step surface modification. The stan…
Steel-Based Electrocatalysts for Efficient and Durable Oxygen Evolution in Acidic Media
Helmut Schäfer, Karsten Küpper, Mercedes Schmidt +10
High overpotentials, particularly an issue of common anode materials, hamper the process of water electrolysis for clean energy generation. Thanks to immense research efforts up to…
Nanostructured submicron block copolymer dots by sacrificial stamping: a potential preconcentration platform for locally resolved sensing, chemistry and cellular interactions
Peilong Hou, Weijia Han, Michael Philippi +2
Classical contact lithography involves patterning of surfaces by embossing or by transfer of ink. We report direct lithographic transfer of parts of sacrificial stamps onto counter…
Ordered topographically patterned silicon by insect-inspired capillary submicron stamping
Weijia Han, Peilong Hou, Shamaila Sadaf +3
Insect-inspired capillary submicron stamping and subsequent surface-limited metal-assisted chemical etching (MACE) with ammonium bifluoride as HF source is employed for high-throug…
