“…So far as we know, none of the existing reports show the super-slippery surfaces that can work after abrasion for 1,000 cycles (Figure 7d). [15,41,[45][46][47][48][49][50] Besides the WCAs and WSAs after the abrasion, we investigated the sliding speed of water droplets on the tilting surface of the printed sample with diverse lubricant viscosities. The water droplets slid faster on the recovered ARSSs than that without sandpaper abrasion regardless of the viscosity of the lubricant (Figure S7 and Video S6, Supporting Information), which could reach %193 mm s À1 on the recovered ARSS with 5 cSt dimethyl silicone-oil infused, while only %97 mm s À1 for ARSS without abrasion.…”

Flush toilets waste a significant amount of water every day due to the unavoidable adhesions between human waste and the toilet surfaces. Super‐slippery surfaces can repel complex fluids and various viscoelastic solids, however, are easily broken by the mechanical abrasions. Herein, we report the fabrication of an abrasion‐resistant super‐slippery flush toilet (ARSFT) using a selective laser sintering 3D printing technology. Unlike traditional super‐slippery surfaces with limited thicknesses which can be easily worn away, the powder sintered strategy endows the ARSFT not only with a self‐supporting 3D complex shape but also with a porous structure that can accommodate considerable lubricants for an abrasion‐resistant super‐slippery property. As a result, the as‐prepared ARSFT remains clean after contacting with various liquids such as milk, yogurt, highly sticky honey and starch gel mixed congee, demonstrating excellent repellence to complex fluids. Besides liquids, the ARSFT exhibits a high resistance to the sticky synthetic feces. Notably, even after being abraded to 1000 cycles of abrasion using sandpaper, the ARSFT maintains its record‐breaking super‐slippery capability. The concept of the 3D printed object with a superior abrasion‐resistant slippery ability will improve the development of super‐slippery materials and further save water consumption in the human society.This article is protected by copyright.

Investigating important challenges to eliminate crude oil fouling in pipelines needs to be studied thoroughly. According to environmental and economic issues, fouling in pipelines increases the price of crude oil. According to chemical and environmental experts, the loss in heat required additional energy to compensate which meant higher fuel consumption and more carbon emissions into the atmosphere. The increase in fluid flow rate combined with a constant drop in pressure is dangerous for pipelines. In addition, the Iraqi crude oils block refinery preheat trains because they contain very little asphaltene. The fouling of a variety of these crude oils and their blends is examined in this paper. Fouling may be caused by four major processes: solid particles, corrosion, sedimentation, and chemical reaction.

PTFE‐based superhydrophobic coatings have received increasing research and the fabricated coatings exhibited excellent anti‐corrosion, anti‐scaling, anti‐fouling, and anti‐icing properties. In order to further enhance the hydrophobicity of PTFE coating, a PTFE‐based coating consisted of nano‐silica and polydimethylsiloxane (PDMS) was fabricated by deposition coating and annealing treatment. The water contact angle and sliding angle of the coating achieved 160.65° and 3.02°, respectively, demonstrating it possessed superhydrophobic property. Due to its excellent surface feature, the coating exhibited resistance to milk, coffee, and mud water, and could be easily cleaned by water flow. Besides, the water droplet on the coating had a longer freezing time and the ice droplet could be easily removed from the coating. Ascribed to the abundant nonpolar groups and the air cushion formed under water, the prepared coating had outstanding anti‐scaling and anti‐corrosion properties. The electrochemical impedance of the steel plate with the coating (above 9000 Ω·cm2) increased by two orders of magnitude compared with the non‐coating one (78.2 Ω·cm2), and the anti‐scaling rates of the coating towards BaSO4 and SrSO4 were all above 80%. It is promising that the coating will be a competitive candidate in many application fields.
