Other claims from this paper (13)
- Observation The adaxial and abaxial surfaces of carob leaflets show hydrophobic and superhydrophobic behaviour, respectively.
- Observation Monopalmitin ester is present in the epicuticular and intracuticular wax layers of the adaxial surface of carob leaflets.
- Observation Palmitic acid is present in the epicuticular and intracuticular wax layers of the adaxial surface of carob leaflets.
- Observation The epicuticular wax of carob leaflets forms a randomly oriented, intricate network of nanometer-thick and micrometer-long plates.
- Observation The density and degree of interconnection of the wax plates are significantly higher in the abaxial surface of carob leaflets.
- Observation The abaxial surface of carob leaflets has tilting angles of 12–70° indicating unusual variable density and water adhesion of the plate texture.
- Observation Light reflectance of the glaucous abaxial surface is significantly higher than that of the nonglaucous adaxial surface of carob leaflets.
- Observation Light absorbance of the glaucous abaxial surface is significantly lower than that of the nonglaucous adaxial surface of carob leaflets.
- Observation Diffuse reflectance is dominant on both carob leaflet surfaces.
- Observation The absorbance of carob leaflet surfaces is weakly dependent on the light incidence angle.
- Mechanism The highly dense nanostructured platelike texture of the epicuticular abaxial layer is asserted to reflect solar radiation diffusely and so lower surface temperature.
- Mechanism The nanostructured platelike texture is asserted to enable gas exchange, transpiration and evaporation in carob leaflets.
- Recommendation Reproducing the wax texture with 1-octacosanol-grafted siloxane hybrid materials is proposed as a suitable route to duplicate the carob abaxial surface with high fidelity.
