An iron nitride complex.
Coordination compounds of iron in high oxidation states have been invoked as reactive intermediates in biocatalyses. Iron(IV) ferryl species are examples of such highly reactive species that have long been known to be at the catalytic centers of oxygenases. Supported by X-ray diffraction studies on nitrogenase, the iron nitride moiety has recently been suggested to be present at the site of bio...
متن کاملTurbulence in Atomic Hydrogen
Understanding the properties of interstellar turbulence is a great intellectual challenge and the urge to solve this problem is partially motivated by a necessity to explain the star formation mystery. This review deals with a recently suggested inversion technique as applied to atomic hydrogen. This technique allows to determine 3D turbulence statistics through the variations of 21 cm intensit...
متن کاملHydrogen Passivation of Interstitial Iron in Silicon by Annealing with Pecvd Silicon Nitride Films
This paper reports on the effective passivation of interstitial iron in p-type boron-doped silicon via annealing with plasma-enhanced chemical vapour deposited (PECVD) silicon nitride films. The concentration of interstitial iron was shown to reduce by more than 90% after a 30-minute anneal at 600 – 900C with the silicon nitride films present. The most effective hydrogenation of iron was found ...
متن کاملCryopumping of atomic hydrogen
A high-density ultracold spin polarized atomic hydrogen jet’ will be used as an internal target for the experiments NEPTUN and NEPTUN-A,2 which will study spin effects in proton-proton scattering at energies of 400 GeV and 3 TeV at the UNK accelerator being built at Protvino, USSR. The ultimate intensity goaI of this jet is a polarized beam of 10” atoms/s. In order to keep the vacuum pressure i...
متن کاملMechanochemistry of lithium nitride under hydrogen gas.
Hydrogen uptake during the mechanochemistry of lithium nitride under 9 MPa hydrogen pressure has been analyzed by means of in situ solid-gas absorption and ex situ X-ray diffraction (XRD) measurements. In situ hydrogenation curves show two H-sorption steps leading to an overall hydrogen uptake of 9.8 wt% H after 3 hours of milling. The milled end-products consist of nanocrystalline (∼10 nm) LiN...
