Slippery Polymer Monoliths: Surface Functionalization with Ordered MoS2 Microparticle Arrays
Weijia Han, Siwei Luo, Dirk Bröker +4
Components of technical systems and devices often require self-lubricating properties, which are implemented by means of dry lubricants. However, continuous lubricant coatings on t…
Evaluation of 3D gold nanodendrite layers obtained by templated galvanic displacement reactions for SERS sensing and heterogeneous catalysis
Weijia Han, Elzbieta Stepula, Michael Philippi +2
Dense layers of overlapping three-dimensional (3D) gold nanodendrites characterized by high specific surfaces as well as by abundance of sharp edges and vertices creating high dens…
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…
