Nitrogenase FeMoco investigated by spatially resolved anomalous dispersion refinement.

The [Mo:7Fe:9S:C] iron-molybdenum cofactor (FeMoco) of nitrogenase is the largest known metal cluster and catalyses the 6-electron reduction of dinitrogen to ammonium in biological nitrogen fixation. Only recently its atomic structure was clarified, while its reactivity and electronic structure remain under debate. Here we show that for its resting S=3/2 state the common iron oxidation state as...

Comparative electronic structures of nitrogenase FeMoco and FeVco

The electronic structures of the nitrogenase active sites, FeMoco and FeVco, have been investigated by a parallel study of the holoenzymes with synthetic cubane cluster models. Using high-resolution X-ray spectroscopies coupled with density functional theory calculations, key diff erences between FeMoco and FeVco have been identifi ed, rationalizing the isozymes’ diff erential affi nity for var...

π-Plasmon Dispersion in Free-Standing Monolayer Graphene Investigated by Momentum-Resolved Electron Energy-Loss Spectroscopy

Graphene is a single layer of carbon atoms densely packed in a honeycomb lattice with each carbon atom accommodating four valence electrons: one π electron and three σ electrons [1]. The lone unpaired π electron in the half-filled pz orbital would form a π bond with the neighboring carbon atoms leading to delocalized π bands. Three σ electrons, sp 2 -hybridized with neighboring three carbon ato...

The dielectric properties of Co-implanted SiO2 investigated using spatially-resolved EELS

Metallic quantum dots implanted in a silicon dioxide thin layer, grown on a silicon substrate, show promising field emission properties, giving an emission current of 1nA at electric fields as low as 5V/μm. This value is achieved for an implantation dose 5x10 16 ions/cm 2 , compared to 120 V/μm for the lowest dose. Electron microscopy reveals that the Co dots form metallic spheres, with a narro...

The spatially resolved refractometer.

PURPOSE To investigate factors controlling the aberrations of the eye, including accommodation, wavelength, and the apodization of the optics of the eye by cone directional selectivity. METHODS We constructed a new implementation of the Spatially Resolved Refractometer (SRR). This is an instrument, based on the Scheiner principle, that allows the rapid psychophysical measurement of the comple...
