In response to the hazards of icing in the energy, transportation, and aerospace sectors, extensive research has been conducted on anti‐icing materials based on the solid‐liquid/ice interface theory, as well as reliable chemical and electro‐thermal de‐icing systems. However, there is an urgent need for modernizing anti‐icing systems to address diverse application scenarios. Gaining insights into the influence of interface action forces on water droplet behavior can proactively prevent detrimental icing occurrences. Nevertheless, under severe conditions where ice formation is inevitable, leveraging interface action forces to induce cracking and expansion of ice facilitates its rapid detachment despite potential challenges associated with complete removal. A comprehensive review elucidating the mechanisms through which interface action forces impact water/ice formations encompasses various approaches toward designing mechanically‐driven de‐icing systems.

Grain size refinement is one of the most effective and feasible approaches to tailor the mechanical properties of metals and alloys. This classic strengthening mechanism is recently highlighted in Ni-Co-Cr-Fe-based high-entropy alloys due to its extremely large Hall–Petch coefficient of 1100 MPa·μm1/2. However, the grain growth kinetics of Ni-Co-Cr-Fe, which serve as the guideline for controlling the grain size of related high-entropy alloys (HEAs), are still unclear. Here, we investigated the grain growth behaviors of Ni2CoCrFe, NiCo2CrFe, and NiCoCrFe2. Our results show that the grain growth kinetics of Ni-Co-Cr-Fe are highly dependent on the concentration of its principal elements. The grain growth activation energies are 315, 622, and 570 KJ/mol for Ni2CoCrFe, NiCo2CrFe, and NiCoCrFe2, respectively. This big difference is mainly attributed to the degree of grain boundary segregation caused by the interactions between different atomic pairs. These findings are helpful for designing HEAs with controllable microstructures.

Developing a durable multifunctional superhydrophobic coating on polymeric films that can be industrially scalable is a challenge in the field of surface engineering. This article presents a novel method for a scalable technology using a simple single-step fabrication of a superhydrophobic coating on polymeric films that exhibits excellent water-repelling and UV-blocking properties, along with impressive wear resistance and chemical robustness. A mixture of titanium precursors, tetraethylorthosilicate (TEOS), hydrophobic silanes and silica nano/micro-particles is polymerized directly on a corona-treated polymeric film which reacts with the surface via siloxane chemistry. The mixture is then spread on polymeric films using a Mayer rod, which eliminates the need for expensive equipment or multistep processes. The incorporation of silica nanoparticles along with titanium precursor and TEOS results in the formation of a silica–titania network around the silica nanoparticles. This chemically binds them to the activated surface, forming a unique dual-scale surface morphology depending on the size of the silica nanoparticles used in the coating mixture. The coated films were shown to be superhydrophobic with a high water contact angle of over 180° and a rolling angle of 0°. This is due to the combination of dual-scale micro/nano roughness with fluorinated hydrocarbons that lowered the surface free energy. The coatings exhibited excellent chemical and mechanical durability, as well as UV-blocking capabilities. The results show that the coatings remain superhydrophobic even after a sandpaper abrasion test under a pressure of 2.5 kPa for a distance of 30 m.
