Synthesis
While many applications exploit the spatial confinement and field enhancement in the vicinity of plasmonic metal nanostructures, much less attention has been given to the field enhancement that occurs inside the metal. One phenomenon that hinges on this effect is the photoemission of electrons from nanostructured metals after excitation by ultrashort laser pulses. Several studies have investigated such ultrafast photoemission from planar films,(4) islandised metal films(5) and metallic gratings.(6, 7) In each of these studies,

Synthesis of an Orthopedic Cement by the Addition of Anhydrous Calcium Hydrogen Phosphate to Calcium Sulfate Hemihydrate
Abstract Commercially available calcium sulfate hemihydrate (CSH) powders were mixed with anhydrous calcium hydrogen phosphate (monetite) in order to develop a novel resorbable orthopedic cement. The setting solution, distilled water, converted the CSH into gypsum as proven by an X-ray diffraction. This conversion into gypsum is what gives the cement its high compressive strength. The addition of monetite gives the cement a high bioresorbablity and remodeling ability that is not present in the pure CSH
