Protection of Glass from Corrosion with Graphene

Studies in the Center of Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) have shown protection of glass from corrosion by graphene coating.
Glass is a most common packaging material for protection of medicine and chemicals due to its high degree of resistivity towards corrosion and chemicals. However, some glass types can corrode over time at high humidity and pH conditions which will cause to decrease in its transparency and strength. Therefore, silicate glass corrosion under high humidity is a most serious problem especially for pharmaceutical, environmental and optical industries in hot and humid climates.
With the adsorption of water on the glass surface, hydrogen ions of water diffuse into glass and exchange with the sodium ions present in the glass surface. Then, pH of the water near the glass surface increases leading to dissolving of silicate structure of glass. To protect the glass surface, thin, transparent and good barrier material to chemical attack are needed for an ideal protective coating. Single layer Graphene with its chemical inertness, thinness and high transparency makes Graphene very promising for the coating of glass surface. In addition, Graphene can act as barrier for the chemical attacks. Therefore, Graphene can be used as protective layer for corrosion, oxidation, friction, bacterial infection, electromagnetic radiation etc.
According to the research at IBS, one or two atom thick layer can protect the glass from corrosion and scientist says that if the production of large amounts of higher quality graphene sheets on the glass surface is reached, then graphene coating on glass will be applicable in industrial scale.

Carbon Nanotubes Specifications and Properties Carbon Nanotubes, simply CNTs, are allotropes of carbon with a round and hollow nanostructure. These barrel shaped carbon molecules have crucial properties, which are significant for nanotechnology, hardware, optics and other different fields of materials science and innovation. The carbon nanotube’s excellent quality as a strong and firm material laid the basis on many applications. Not to mention carbon nanotubes exceptional heat conductivity, electrical and mechanical properties, Carbon Nanotubes are used as additives to diverse auxiliary materials. In terms of rigidity and flexibility Carbon Nanotubes are the stiffest and strongest materials. These quality outcomes from the covalent sp2 bonds framed between the individual carbon molecules. Unlike Graphene , Carbon Nanotubes are either conductive or semiconducting along the tubular hub. Carbon Nanotubes also have absorption, fluorescence properties. Bulk Carbon nanotubes are util...

Hydroxyapatite Nanopowders and Their Applications

Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder  is the main inorganic constituent of bon...
