“…Results of spraying depend on the characteristics of the leaf surface, such as the presence of hairs, the chemical composition of the epicuticular wax, or the deposition of wax platelets (Pezzarossa et al., 2012). Rich and Pokroy (2018) informed that the surface of broccoli leaves is super repulsive and self‐cleaning with respect to water. Therefore, it is highly recommended to use adjuvants during foliar application in broccoli to facilitate the entry of selenium into the plant.…”

Selenium‐biofortified broccoli (Brassica oleracea L. var. italica Plenck) is an important source of micronutrients in a healthy human diet. Therefore, studies are needed on the commercial production of selenium‐enriched broccoli. We analyzed the effect of the foliar application of sodium selenate and sodium selenite in doses of 50 and 100 g ha−1 on the growth, photosynthetic parameters, selenium accumulation, and commercial quality of broccoli in two cultivars (‘Belstar’ and ‘Legend’) used for fresh crops market grown under field conditions. The application of both doses of selenate and the highest dose of selenite induced a significant increase in the head fresh weight (FW) only in cultivar Belstar. However, the dry matter content of the heads was not significantly affected by selenium or the cultivar of broccoli. In addition, the increase in the water use efficiency, mainly due to the reduction of the transpiration rate, could explain the significant increase in the head FW without modifying the head dry matter content in Belstar. On the other hand, selenium treatments before harvest maintained the green color and did not affect the firmness and diameter of the heads at harvest. The selenium content of the heads increased markedly in a dose‐dependent manner in both cultivars, with both selenium treatments. The results of this study indicate that the response to selenium treatments differs between broccoli cultivars and that the use of both selenium salts in foliar form would be a good strategy to obtain selenium‐enriched broccoli, without affecting the commercial quality of the heads.

“…Over millions of years, plants and animals have evolved a spectrum of surface designs enabling specific wetting properties tailored for their survival in extreme conditions [1–4]. In plants, the unique surface architecture of the lotus leaf enables superhydrophobic and self-cleaning properties for sustaining efficient photosynthesis, even in polluted environments [5–7]. In the realm of animals, mosquitos utilize an antifog coating covering their eyes for clear vision in high humidity regions [8].…”

We report on the synthesis of highly oriented and nanostructured metal–organic framework (MOF) films featuring extreme surface wetting properties. The Ni- and Co- derivatives of the metal–catecholate series (M-CAT-1) were synthesized as highly crystalline bulk materials and thin films. Oriented pillar-like nanostructured M-CAT-1 films exhibiting pronounced needle-like morphology on gold substrates were established by incorporating a crystallization promoter into the film synthesis. These nanostructured M-CAT-1 MOF films feature extreme wetting phenomena, specifically superhydrophilic and underwater superoleophobic properties with water and underwater oil-contact angles of 0° and up to 174°, respectively. The self-cleaning capability of the nanostructured, needle-like M-CAT-1 films was illustrated by measuring time-dependent oil droplet rolling-off a tilted surface. The deposition of the nanostructured Ni-CAT-1 film on a large glass substrate allowed for the realization of an efficient, transparent, antifog coating, enabling a clear view even at extreme temperature gaps up to ≈120 °C. This work illustrates the strong link between MOF film morphology and surface properties based on these framework materials.

“…Detailed microscopic analysis of the lotus leaf reveals the presence of 𝜇m-sized mounds consisting of waxy nanoscale hairs imparting superhydrophobicity. [8][9][10] Recent developments in preparation, properties, and applications of SH coatings and surfaces have been delineated in several reviews. [11][12][13][14][15] SH coatings are typically prepared by using fluorinated or siloxane-containing formulations.…”

A superhydrophobic coating, free of fluorinated and siloxane materials, has been prepared via reactive compatibilization of all organic blends of hydrophilic and hydrophobic materials. In this case, styrene acrylic emulsion and a combination of hydrophobic waxes (functional rice bran wax and functional polypropylene wax) are blended together in the presence of polycarbodiimide as the reactive compatibilizer. The effect of blending and crosslinking on surface morphology is studied by Fourier transform infrared spectroscopy analysis, microscopy analyses (SEM and AFM), contact angle, and surface energy measurements. After heat treatment and crosslinking, synergistic improvements of surface properties with a gradual trend toward superhydrophobicity are observed (water contact angle ≈144°and roll-off angle of <10°). The system is free of nanoparticles, and the desired surface morphology and microstructure is formed from the mixture of renewable (rice bran) wax and petrochemical (polypropylene) wax. These coatings are shown to have easy-cleaning as well as self-cleaning characteristics. Further, the coatings can withstand exposure to solvents as well as mechanical abrasion.
