Water Droplet Hammer: Piezoelectric Sensing of Ultrafast Mechanical Transients During Droplet Impact
Small, Volume 22, Issue 51, 11 September 2026.Droplet impact on solid surfaces produces an ultrafast substrate‐coupled mechanical response that is resolved by PVDF piezoelectric sensing. An initial impulsive strain pulse is followed by interfacial oscillations before rebound. Weber‐number and timescale analyses reveal how droplet inertia, surface wettability, impact regime, and liquid viscosity ...

Small, Volume 22, Issue 53, 21 September 2026.LiDIA is an on‐demand droplet‐in‐air platform that enables synchronized droplet collision, ultralow‐waste operation, and obstruction‐free sample delivery. By combining precise triggering with reliable free‐space dispensing, it provides a versatile route for rapid mixing and time‐resolved studies, with strong potential for applications in XFEL, cryo‐EM,

Spatially Patterned Condensation Arrays Driven by Evaporating Droplets
Small Structures, Volume 7, Issue 9, September 2026.The coupling of evaporation and condensation via a thin substrate creates a model for configurable condensation patterns. The spatial organization of the condensates is manipulated by the substrate geometry and the movement of the contact line, providing design principles for energy‐efficient microfluidic and thermal management systems.

It is well known that the roughness of a hydrophobic solid enhances its hydrophobicity. The contact angle of water on such flat solids is typically of the order of 100 to 120 degrees, but reaches values as high as 160 to 175 degrees if they are rough or microtextured.

Faraday Discussions, 2010
Superhydrophobicity is mainly remarkable for the special dynamical behaviours it generates: low adhesion, giant hydrodynamic slip, frictionless motion, rebounds after impacts. Here we discuss most of these properties. We first recall how contact angle hysteresis can be minimized in this state.

Multifunctional superhydrophobic surfaces
Advances in Colloid and Interface Science, 2021Surface wetting has a significant influence on the performance and applications of the materials. The superhydrophobic surfaces have water repellency due to low surface energy chemistry and micro/nanostructure roughness. The amazing applications of superhydrophobic surfaces (SHSs) lead to increase attention to superhydrophobicity in recent decades. The

Metastable Underwater Superhydrophobicity
Physical Review Letters, 2010Superhydrophobicity is generally considered to be a thermodynamically stable wetting state. The stability of the plastron (the thin air film separating the substrate from the water in the superhydrophobic state) was studied in underwater experiments. The plastron exhibited a rapid decay after a well defined onset time, which was found to be dependent ...
