Fe/ZSM-5 nanosheet zeolites of varying thickness were synthesized with di- and tetraquaternary ammonium structure directing agents and extensively characterized for their textural, structural, and catalytic properties. Introduction of Fe3+ ions in the framework of nanosheet zeolites was slightly less effective than in bulk ZSM-5 zeolite. Steaming was necessary to activate all catalysts for N2O ...

We complement our study of α/Fe enhanced stellar population models of Lick absorption indices (Thomas et al., 2003) by comparing two sets of α/Fe enhanced models. In both models the impact on Lick indices due to α/Fe enhancement is accounted for through a modification of the stellar absorption line-strengths using the response functions of Tripicco & Bell (1995). One set of models, however, use...

Single crystals of the iron tetrapolyvanadate Fe(2)V(4)O(13) and the iron polyvanadomolybdate Fe(2)V(3.16)Mo(0.84)O(13.42) were grown from Fe(2)O(3)/V(2)O(5) and Fe(2)O(3)/V(2)O(5)/MoO(3) melts, respectively. Single-crystal X-ray diffraction revealed that the two structures are closely related. Both contained isolated Fe(2)O(10) octahedral dimers with similar orientations. The unusual U-shaped ...

New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

In aerobic, circumneutral environments, the essential element Fe occurs primarily in scarcely soluble mineral forms. We examined the independent and combined effects of a siderophore, a reductant (ascorbate), and a low-molecular-weight carboxylic acid (oxalate) on acquisition of Fe from the mineral hematite (alpha-Fe(2)O(3)) by the obligate aerobe Pseudomonas mendocina ymp. A site-directed Delt...

A new mechanism of the Verway transition in magnetite (Fe3O4), which has been argued to be a charge ordering transition so far, is proposed. Based on the mean field calculations for the three band model of spinless fermions appropriate for the d electrons of the Fe ions on the B sites, it is indicated that the phase transition should be the bond dimerization due to the cooperative effects of st...

The first examples of boryl substituted aluminylene and gallylene complexes, [(DAB)B(THF)Al{Fe(CO)3(μ-CO)}]2 and [(DAB)BGa{μ-Fe(CO)4}]2 (DAB = {(C6H3Pri2-2,6)NCH}2) have been prepared by reduction of MX2(THF){B(DAB)} (M = Al or Ga, X = Cl or Br) with K2[Fe(CO)4]. Spectroscopic and crystallographic analyses of the compounds show them to be structurally distinct dimers, the latter of which posses...

Metallic glasses with conventional glass-forming ability (Al-Fe-Nd, Fe-Zr-B, Fe-B-Nb compositions) and bulk metallic glasses (Ca-Mg-Cu compositions) were studied by synchrotron X-ray diffraction during annealing throughout glass transition and crystallization temperatures. The analysis of the first diffraction peak position during the annealing process allowed us to follow the free volume chang...
