Synthesis and Characterization of the Linear Trinuclear Complexes [M(O2CCH3)6(biphme)2], M = Mn, Fe

R. Lynn Rardin、Avi Bino、Peter Poganiuch 等 6 位作者1990-07-01Angewandte Chemie International Edition in English

A Mn3 chain bridged by four bidentate and two monodentate carboxylate ligands characterizes the MnII title complex 1. Unique features are the monodentate acetate bridges, which have a “dangling” oxygen atom that influences the molecular structure through weak interactions with the terminal Mn atoms.

Salt Effects on Growth and Ion Uptake of Pistachio Rootstock Seedlings

Geno A. Picchioni、S. Miyamoto、J. Benton Storey1990-07-01Journal of the American Society for Horticultural Science

The degree of salt resistance of Pistacia spp. grown in the western United States is not adequately known. This study evaluated seedling growth and ion uptake characteristics of two Pistacia spp. and one hybrid in outdoor lysimeters for two seasons. After 12 weeks, seedling stem elongation of P. atlantica Desf., P. te…

Polarisation Conversion through the Excitation of Surface Plasmons on a Metallic Grating

G. P. Bryan‐Brown、J. R. Sambles、M.C. Hutley1990-07-01Journal of Modern Optics

Surface plasmon-polaritons may be excited by photons at a metal-air boundary if a grating is used to provide the necessary extra momentum. Rotation of the grating so that the grooves are no longer perpendicular to the plane of incidence reduces the coupling efficiency while at the same time producing some s-polarised…

Abstract In order to develop new composite materials between reactive metals and polymers, it is proposed to place organic monomers at the metal/polymer phase boundary, which can be coupled by covalent/ionic bonds to reactive centres of the metal substrate and later by covalent bonds to the polymer itself. As a first…

Abstract The energies of photoelectron and Auger lines of gallium and nitrogen in GaN thin films obtained by reactive sputtering are derived. From previous RBS investigations, such were found to be stoichiometric in the bulk. The XPS surface analysis of the films gives a chemical content of ∼20% gallium oxide. Depth p…
