Self‐Driving Underwater “Aerofluidics”
Advanced Science, 2023 Here, the concept of “aerofluidics,” in which a system uses microchannels to transport and manipulate trace gases at the microscopic scale to build a highly versatile integrated system based on gas‒gas or gas‒liquid microinteractions is proposed.

Rapid fabrication of superhydrophobic high-silicon aluminum alloy surfaces with corrosion resistance
Results in Physics, 2019 High-silicon aluminum alloy (high-Si Al alloy) usually used as the electronic packaging materials on the radar on ships have a susceptibility to corrosion, reducing the life of radar on ships. How to improve the corrosion-resistance ability of high-Si Al

Immersed superhydrophobic surfaces: Gas exchange, slip and drag reduction properties [PDF]
, 2009 Superhydrophobic surfaces combine high aspect ratio micro- or nano-topography and hydrophobic surface chemistry to create super water-repellent surfaces. Most studies consider their effect on droplets, which ball-up and roll-off.

Superhydrophobic Blood‐Repellent Surfaces [PDF]
Advanced Materials, 2018 AbstractSuperhydrophobic surfaces repel water and, in some cases, other liquids as well. The repellency is caused by topographical features at the nano‐/microscale and low surface energy. Blood is a challenging liquid to repel due to its high propensity for activation of intrinsic hemostatic mechanisms, induction of coagulation, and platelet activation

Quantum vacuum photon-modes and superhydrophobicity [PDF]
, 2015 Nanostructures are commonly used for developing superhydrophobic surfaces. However, available wetting theoretical models ignore the effect of vacuum photon-modes alteration on van der Waals forces and thus on hydrophobicity.

Superhydrophobicity on Hairy Surfaces [PDF]
Langmuir, 2010 We investigate the wetting properties of surfaces patterned with fine elastic hairs, with an emphasis on identifying superhydrophobic states on hydrophilic hairs. We formulate a two dimensional model of a large drop in contact with a row of equispaced elastic hairs and, by minimising the free energy of the model, identify the stable and metastable ...

Manipulation of the Superhydrophobicity of Plasma-Etched Polymer Nanostructures
Micromachines, 2018 The manipulation of droplet mobility on a nanotextured surface by oxygen plasma is demonstrated by modulating the modes of hydrophobic coatings and controlling the hierarchy of nanostructures. The spin-coating of polytetrafluoroethylene (PTFE) allows for

Review on Blueprint of Designing Anti-Wetting Polymeric Membrane Surfaces for Enhanced Membrane Distillation Performance [PDF]
, 2019 Recently, membrane distillation (MD) has emerged as a versatile technology for treating saline water and industrial wastewater. However, the long-term use of MD wets the polymeric membrane and prevents the membrane from working as a semi-permeable ...
