The photoemission properties of thin diamond and fullerene films were investigated for advanced accelerator applications, using subpicosecond laser pulses at three different wavelengths (650, 325, and 217 nm). The quantum efficiency (QE) obtained at 217 nm with a boron-doped, p-type, (111) polycrystalline diamond film (2.6 lop4) was only five times smaller than the QE obtained with a mirror pol...

Abstract In order to improve the interfacial bonding between copper and graphite, was coated on graphite by electroless plating. Copper/graphite composites with copper‐coated were fabricated spark plasma sintering. The effects of density, electrical conductivity, mechanical properties, friction wear properties copper/graphite studied. results show that: plating surface can wettability copper, i...

In 1924, Hart, Elvehjem and coworkers demonstrated that copper is essential for erythropoiesis in most, if not all, mammalian species (1). Since that time many studies have been performed in attempts to elucidate the manner in which copper functions in erythropoiesis, but as yet this mechanism is not understood. Recent studies in this laboratory (2) have indicated that the amount of copper in t...
