failure of artificial implant restorative procedure has been due to the wear of components with subsequent bone resorption and aseptic loosening that limits the lifespan of implants. Multiple different materials made from stainless steel‚ cobalt‚ chromium‚ titanium‚ and tantalum have been tested throughout history as replacements for bone.

Green Oxidation of Borneol to Camphor Abstract: This lab converted borneol to camphor using a green oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol

She quickly introduces images that are associated with cities; ‘smell of smog’‚ ‘chromium plated offices’‚ ‘subways crowded at rush hours.’ These images are interspersed with images of nature that is controlled or influenced by man; ‘the almost not smell of tulips’ is drowned by the aforementioned ‘smog’. Nature in the city is ‘tidily
