Uniting Superhydrophobic, Superoleophobic and Lubricant Infused Slippery Behavior on Copper Oxide Nano-structured Substrates.
TL;DR: A facile and economical way to generate copper oxide micro-nano structures with spherical, needle, needle and hierarchical cauliflower morphologies on galvanized steel substrates using a simple chemical bath deposition method is demonstrated.
Mechanically Tunable Slippery Behavior on Soft Poly(dimethylsiloxane)-Based Anisotropic Wrinkles Infused with Lubricating Fluid.
TL;DR: In this paper, a technique to fabricate mechanically tunable slippery surfaces using one-dimensional (anisotropic) elastic wrinkles is presented. But the approach is limited to the case of a single-dimensional surface.

Slipperiness and stability of hydrophilic surfaces coated with a lubricating fluid
TL;DR: In this paper, a method to fabricate stable slippery surfaces on hydrophilic samples, which are more commonly and widely used, was presented, where water drops on the slippery surfaces were found to be enveloped, or cloaked, in a thin layer of the lubricating oil.

Mechanically Tunable Slippery Behavior on Soft Poly(dimethylsiloxane) (PDMS) Based Anisotropic Wrinkles Infused with Lubricating Fluid
TL;DR: In this paper, the authors demonstrate a technique to fabricate mechanically tunable slippery surfaces using one dimensional (anisotropic) elastic wrinkles, which show tunable topography (amplitude) on the application of mechanical strain.

Sink dynamics of aqueous drops on lubricating fluid coated hydrophilic surfaces
TL;DR: In this article, the sink time of aqueous drops depends on both the wettability of the substrate as well as viscosity of the lubricating layer, while the final apparent contact angle depends only on the substrate's wetability.
