Phase‐Change‐Activated Slippery Organogel Composite for All‐in‐One Anti‐Corrosion, Antifouling, and Self‐Cleaning

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A super‐slippery liquid‐infused composite organogel is engineered by localized interfacial grafting between hydrogel and oleogel networks, endowing the coating with a durable, multifunctional marine‐protective interface. Dynamic antifouling surfaces have emerged as a promising alternative, offering the potential for eco‐friendly and high‐performance ...

Polarization singularities in the clear sky

, 2004
Ideas from singularity theory provide a simple account of the pattern of polarization directions in daylight. The singularities (two near the Sun and two near the anti-Sun) are points in the sky where the polarization line pattern has index +1/2 and the ...

Cu‐Doped Amorphous High‐Entropy Hydroxides Activating Electrochemical Reconstruction: Triggering LOM and Chloride Repellency for Enhanced Water and Seawater Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Copper‐doped amorphous high‐entropy hydroxide (CuNiCoFeCrOH) is constructed via one‐step electrodeposition. Cu doping promotes electrochemical reconstruction by accelerating Cr leaching and re‐adsorption, triggering LOM and chloride repellency for efficient water and seawater oxidation.

Corrosion‐Protection of T122 Steel Using g‐C3N5‐Embedded Epoxy Coatings

Materials and Corrosion, EarlyView.
Study evaluates g‐C3N5 (CN) reinforced epoxy coatings on T122 steel in NaCl and H2SO4. Electrochemical tests revealed that 2% loading maximizes corrosion resistance by blocking pores and limiting ion diffusion, increasing Rp and Rn. Optimized CN content enhances epoxy coating performance overall system durability material. ABSTRACT Corrosion‐protection
