Summary: Periodate, a platform oxidizer, can be recycled through electrochemical re-oxidation in the presence of organic impurities. Cold combustion of organic compounds to CO2 and H2O provides orthogonal conditions for periodate synthesis. This strategy can be used to degrade organic contaminants and control the purity of periodate.

Summary: Using molecular simulations, researchers explain the self-cleaning mechanisms on superhydrophobic surfaces by understanding the interactions between particle-droplet and particle-surface at the nanoscale. They present a universal phase diagram that predicts the removal of particles of varying sizes and adhesive strengths from superhydrophobic surfaces.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: The wings of the Formosan subterranean termite have micrometer-scale hairs and nanometer-scale wax patches, which reduce adhesions to water droplets. Inspired by this anti-wetting structure, a colloidal lithography-based strategy integrated with a scalable self-assembly approach was developed to engineer hierarchical conical structure arrays. The resulting superhydrophobic structures had a water contact angle of 175.3 degrees and a low contact angle hysteresis of 2.7 degrees, and featured self-cleaning and anti-fogging capabilities.

Summary: Superhydrophobic transparent coatings have gained attention in solar energy field due to their easy preparation, low cost, self-cleaning process, and effectiveness in reducing dust adhesion. However, their application in the solar energy field is complex. The transparency and roughness needed for self-cleaning are contradictory parameters, and the durability of the coatings is also important. Few reviews focus on superhydrophobic coatings for solar applications.
