RESUMO
Liquid metals (LMs) in an alkaline electrolyte, when placed on a graphite surface, are able to be manipulated into desired flat, stable shapes with sharp angles, like triangles. Unique transformations and worm-like anti-gravity upslope LM locomotion under a low-voltage electric field are also revealed.
RESUMO
A material with superhydrophobic and anti-ice/de-icing properties, which has a micro-/nanostructured surface, is produced by a straightforward method. This material comprises a poly(dimethylsiloxane) (PDMS) microstructure with ZnO nanohairs and shows excellent water and ice repellency even at low temperatures (-20 °C) and relatively high humidity (90%) for over three months. These results are expected to be helpful for designing smart, non-wetting materials that can be adapted to low-temperature environments for the development of anti-icing systems.
