Hydrophilic Slippery Surface Promotes Efficient Defrosting
Langmuir, 2021Frost accretion occurs ubiquitously in various industrial applications and causes tremendous energy and economic loss, as manifested by the Texas power crisis that impacted millions of people over a vast area in 2021. To date, extensive efforts have been made on frost removal by micro-engineering surfaces with superhydrophobicity or lubricity.

The role of surface roughness in the measurement of slipperiness
Ergonomics, 2001Surface roughness has been shown to have substantial effects on the slip resistance between shoe heels and floor surfaces under various types of walking environments. This paper summarizes comprehensive views of the current understanding on the roles of surface roughness on the shoe and floor surfaces in the measurement of slipperiness and discusses ...

Slippery pre-suffused surfaces
EPL (Europhysics Letters), 2011We describe the slippery behaviour of textured solids filled with oil, on which other liquids are found to slip and be removed easily. We describe the criteria for achieving this slippery behaviour, and illustrate the concept by two examples, namely the lotus effect (removal of dust by mobile drops) and the coffee stain effect.

Measuring Road Surface Slipperiness
1964Twenty-one agencies cooperated in comparative tests with trailers, stopping-distance vehicles, and portable testers on five specially prepared surfaces ranging in coefficient of friction (C/F) from extremely low to relatively high. Several secondary experiments were conducted to determine the effects of such variables as water film thickness, changes ...

Antifouling Slippery Surface against Marine Biofouling
Langmuir, 2023Titanium and its alloys have become the most excellent structure materials for naval seawater pipelines due to their high strength and good corrosion resistance. However, marine biofouling poses a serious threat to titanium alloy piping systems because of their good biocompatibility.

Slippery Behavior of PEGylated Surfaces
ACS Applied Materials & InterfacesSlippery hydrophilic surfaces have gained significant attention due to their hydrophilicity and ultralow liquid adhesion, offering excellent biofouling resistance as well as enhanced condensation efficiency. Although polyethylene glycol (PEG) is widely used for such surfaces, the detailed molecular-level mechanism by which PEG chain length governs ...

Life Span of Slippery Lubricant Infused Surfaces
ACS Applied Materials & Interfaces, 2022Since their discovery a decade ago, slippery liquid infused porous surfaces (SLIPSs) or lubricant infused surfaces (LISs) have been demonstrated time and again to have immense potential for a plethora of applications. Of these, one of the most promising is enhancing the energy efficiency of both thermoelectric and organic Rankine cycle power generation

Reflex control of bipedal locomotion on a slippery surface
Advanced Robotics, 2002Biped robots are expected to walk on many different and previously unknown terrains including slippery surfaces on which no prior information is available. It is very important that biped robots have an ability to walk on a slippery surface which it meets so suddenly, since any damage to biped robots will be very costly.

Slippery surfaces using lipids
Science, 2020Hydrogels In engineered systems, a reduction in friction can come from the use of lubricants or through surface coatings that are inherently slippery. For most hydrogels, which are cross-linked polymers heavily swelled with water, surface lubrication typically comes from trapped liquids that help to form a slippery surface.

Annual Review of Materials Research
Slippery surfaces are characterized by their ability to minimize contact line pinning, with performance governed not by large apparent contact angles but by low contact angle hysteresis. This review outlines the physical principles governing slipperiness and the mechanisms of contact angle hysteresis, followed by discussing three major engineering ...
