Hierarchical structures with dimensions of features ranging from the macroscale to the nanoscale are extremely common in nature and possess properties of interest. There are a large number of objects including bacteria, plants, land and aquatic

• .’ It means mimicking biology or nature. Nature has gone through evolution over the 3.8 billion years since life is estimated to have appeared on the Earth [1]. Nature has evolved objects with high performance using commonly found materials. These function on the macroscale to the nanoscale. The

Zhu and Granick [59] have reported that the slip length increases from nanometer range to micrometer range as the flow

In theory, the interaction of an ideal sphere with an atomically flat surface is, e.g., described by the Derjaguin–Muller–Toporov (DMT) model [20] or the

• replicated in Figure 8. The application of high-frequency vibrations to ease sliding has been reported on the macroscale already in 1959 [29], with the most recent investigation (in-plane motion) by Popov et al. [30]. Socoliuc et al. [31] have reported on atomic-scale experiments. In the latter case
