Crystalline yttrium oxide films have been grown on Si (0 0 1) and sapphire (0001) substrates by molecular beam epitaxy using molecular oxygen and thermal evaporation of yttrium. Neodymium doped films showed strong room temperature photoluminescence f

The aggregation of amyloid beta peptide (A beta) into its fibrillar, cross beta-pleated configuration is generally viewed as a critical event in the pathophysiology of Alzheimer's disease (AD). A diverse group of molecules, the A beta binding protein

Appreciation of the role that inflammatory mediators play in Alzheimer's disease (AD) pathogenesis continues to be hampered by two related misconceptions. The first is that to be pathogenically significant a neurodegenerative mechanism must be primar

Single-crystal aluminum-gallium oxide films have been grown by molecular beam epitaxy in the corundum phase. Films of the (Al(1-x)Ga(x))(2)O(3) alloys doped with neodymium have favorable properties for solid-state waveguide lasers, including a high-t

Epitaxial films of neodymium-doped sapphire have been grown by molecular beam epitaxy on R-, A-, and M-plane sapphire substrates. The emission spectrum features sharp lines consistent with single-site doping of the Nd(3+) ion into the host crystal. T

Nd:Sapphire films grown by molecular beam epitaxy produce sharp emission lines due to identical-site doping not observed in bulk sapphire crystals. The 1096 nm line is a lasing candidate with an Nd:YVO4-like emission cross section.
