A fundamental limitation of liquids on many surfaces is their contact line pinning. This can be overcome by infusing a nonvolatile and immiscible liquid or lubricant into the texture roughness created in applied onto solid substrate so that interest no longer directly contacts underlying surface. Such slippery liquid-infused porous (SLIPS), also known as lubricant-impregnated surfaces, completely remove pinning angle hysteresis. However, although sessile droplet may rest such surface, its...
Superhydrophobic coatings and slippery liquid-infused porous surfaces (SLIPS) have shown their potentials in self-cleaning, anti-icing, anti-erosion, antibiofouling applications. Various studies been done on controlling the droplet impact such using passive methods as modifying lubricant layer thickness SLIPS. Despite effectiveness, lack on-demand control over dynamics of droplets. This paper introduces a new method to actively onto superhydrophobic SLIPS surface acoustic waves (SAWs). In...
Abstract Droplet evaporation on solid surfaces is important in many applications including printing, micro-patterning and cooling. While seemingly simple, the configuration of evaporating droplets solids difficult to predict control. This because typically proceeds as a “stick-slip” sequence—a combination pinning de-pinning events dominated by static friction or “pinning”, caused microscopic surface roughness. Here we show how smooth, pinning-free, non-planar topography promote different...
The critical need for accurate and non-invasive temperature monitoring is prevalent in extreme environments, such as scuba diving. Current measurement technologies present limitations, prompting the development of innovative solutions. We propose integration embroidered wearable thermocouple sensors, demonstrating their versatility reliability real-time monitoring. T-type thermocouples, onto fabric, offer flexibility sensor placement, eliminating skin attachment. results indicate efficient...
A significant limitation for droplet mobility on solid surfaces is to overcome the inherent pinning of droplet's contact line that occurs because chemical/physical heterogeneities. recent innovation use surface texture or porosity create a stabilized lubricant surface. Droplets such slippery liquid-infused porous (SLIPS)/lubricant-impregnated (LIS) are highly mobile layer. Low reduces energy required move droplet; however, it makes difficult accurately position stop its motion altogether. In...
A versatile method for the creation of multitier hierarchical structured surfaces is reported, which optimizes both antiviral and hydrophobic (easy-clean) properties. The methodology exploits availability surface-active chemical groups while also manipulating surface micro- nanostructure to control way coating interacts with virus particles within a liquid droplet. This has significant advantages over single-tier surfaces, including ability overcome droplet-pinning effect in delivering high...
Abstract Soil wettability is important for understanding a wide range of earth system processes, from agricultural productivity to debris flows and sediment fan formation. However, there limited research considering how soil–water interactions, where the soil grains are naturally hydrophobic, might change in presence oil natural hydrocarbon leakage or spills. Here we show slippery liquid‐infused porous surfaces (SLIPS) apply hydrophobic soils, by physical modelling different grain sizes...
