Summary of "Rapid deposition of transparent super-hydrophobic layers on various surfaces using microwave plasma."

We report herein on a very fast and simple process for the fabrication of transparent superhydrophobic surfaces by using microwave (MW) plasma. It was found that the reaction of various organic liquids in MW argon plasma yields hydrophobic polymeric layers on a large assortment of surfaces, including glass, polymeric surfaces, ceramics, metals, and even paper. In most cases, these polymers are deposited as a rough layer composed of 10-15 nm nanoparticles (NPs). This roughness, together with the chemical hydrophobic nature of the coated materials, is responsible for the superhydrophobic nature of the surface. The typical reaction time of the coating procedure was 1-10 s. The stability of these superhydrophobic surfaces was examined outdoors, and was found to last 2-5 days under direct exposure to the environment and to last 2 months when the sample was protected by a quartz cover. A detailed characterization study of the chemical composition of the layers followed using XPS, solid-state NMR, and IR measurements. Modifications were introduced in the products leading to a substantial improvement in the stability of the products outdoors.

Medical and Biotech [MESH] Definitions

One or more layers of EPITHELIAL CELLS, supported by the basal lamina, which covers the inner or outer surfaces of the body.

The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.

The three primary germinal layers (ECTODERM; ENDODERM; and MESODERM) developed during GASTRULATION that provide tissues and body plan of a mature organism. They derive from two early layers, hypoblast and epiblast.

A replica technique in which cells are frozen to a very low temperature and cracked with a knife blade to expose the interior surfaces of the cells or cell membranes. The cracked cell surfaces are then freeze-dried to expose their constituents. The surfaces are now ready for shadowing to be viewed using an electron microscope. This method differs from freeze-fracturing in that no cryoprotectant is used and, thus, allows for the sublimation of water during the freeze-drying process to etch the surfaces.

The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
