Condensation on Slippery Asymmetric Bumps
TL;DR: A conceptually different design approach is presented—based on principles derived from Namib desert beetles, cacti, and pitcher plants—that synergistically combines these aspects of condensation and substantially outperforms other synthetic surfaces.

Superhydrophobic Melamine Sponge Coated with Striped Polydimethylsiloxane by Thiol-Ene Click Reaction for Efficient Oil/Water Separation.
Peng Jinwen,Deng Junjie,Quan Yiteng,Chuanbai Yu,Hai Wang,Yongyang Gong,Yuanli Liu,Deng Weixing +7 more
TL;DR: This study reports a superhydrophobic and oleophilic melamine sponge functionalized by a uniform polydimethylsiloxane (PDMS) film that can be easily coated onto the sponge skeleton through UV-assisted thiol–ene click reactions and enables the PDMS-coated melamine sponges to be squeezed repeatedly without collapsing.

Bionic PDMS film with hybrid superhydrophilic/superhydrophobic arrays for water harvest
WuYanchun,LiHuilin,WenLulu,MenDandan,HangLifeng,LiuDilong,LiuGuangqiang,CaiWeiping,LyuXianjun,LiYue +9 more
TL;DR: In this article, the authors presented a cheap and facile strategy for fabricating hybrid superhydrophilic/superhydrophobic arrays on a flexible polydimethylsiloxane (PDMS) film to harvest water from fog efficiently.

Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity
Tak Sing Wong,Sung Hoon Kang,Sindy K. Y. Tang,Elizabeth Smythe,Benjamin Hatton,Alison Grinthal,Joanna Aizenberg +6 more
TL;DR: A strategy to create self-healing, slippery liquid-infused porous surface(s) (SLIPS) with exceptional liquid- and ice-repellency, pressure stability and enhanced optical transparency, applicable to various inexpensive, low-surface-energy structured materials (such as porous Teflon membrane).

Four billion people facing severe water scarcity
TL;DR: It is found that two-thirds of the global population (4.0 billion people) live under conditions of severe water scarcity at least 1 month of the year, and nearly half of those people live in India and China.

Insect aquaplaning: Nepenthes pitcher plants capture prey with the peristome, a fully wettable water-lubricated anisotropic surface.
Holger F. Bohn,Walter Federle +1 more
TL;DR: It is demonstrated that the two factors preventing insect attachment to the peristome, i.e., water lubrication and anisotropic surface topography, are effective against different attachment structures of the insect tarsus.

TL;DR: In this paper, a design approach based on principles derived from Namib desert beetles, cacti, and pitcher plants is proposed to maximize vapour diffusion flux at the apex of convex millimetric bumps by optimizing the radius of curvature and cross-sectional shape.
