We evaluated the inducibility of nitrate-dependent Fe(II)-EDTA oxidation (NDFO) in non-growth, chloramphenicol-amended, resting-cell suspensions of Dechloromonas sp. strain UWNR4 and Acidovorax sp. strain 2AN. Cells previously incubated with Fe(II)-EDTA oxidized ca. 6-fold more Fe(II)-EDTA than cells previously incubated with Fe(III)-EDTA. This is the first report of induction of NDFO by Fe(II).
در این مقاله اثرات پدیده کوپلاژ متقابل فازها بر رفتار موتورsr6/4 مورد بررسی قرار گرفته است. با توجه به ضعف توانائی مدلهای اندوکتانسی در مواجه با ماهیت غیر خطی شار برای موتورsr6/4 با تحریک همزمان دوفاز گردیده است که در برگیرنده اثرات پدیده کوپلاژ متقابل فازهاست. اطلاعات شار مورد استفاده در توسعه مدل، از طریق تحلیل fe دوبعدی بدست آمده اند. این اطلاعات گویای اهمیت پدیده کوپلاژ متقابل فازها، به خصو...
abstract: systematic studies on the substituent effect in para substituted fe(co)4–pyridine complexes have been studied on the basis of dft quantum-chemical calculations. the following substituents were taken into consideration: no2, cn, cho, f, h, ch3, and oh. additionally, the fe–n and fe–c bonds were characterized on the basis of atoms in molecules topological analysis of electron density. i...
The Dirac spin liquid ground state of the spin 1/2 Heisenberg kagome antiferromagnet has potential instabilities. This has been suggested as the reason why it does not emerge as the ground state in large-scale numerical calculations. However, previous attempts to observe these instabilities have failed. We report on the discovery of a projected BCS state with lower energy than the projected Dir...
Using structure-directing agents, pore space partitions of a Zn-phosphonocarboxylate framework have been achieved. Selective adsorption of CO(2) over N(2) has been greatly improved from ca. 9 : 1 to 94 : 1.
MagSaki software was developed for the magnetic analysis of dinuclear high-spin cobalt(II) complexes. This software performs magnetic analysis to determine magnetic parameters using several types of theoretical calculations, such as the following: (1) a mononuclear complex in an isotropic octahedral field, (2) a mononuclear complex in an axially distorted octahedral field, (3) a dinuclear compl...
The preparation and spectroscopic characterization of a CO-inhibited [FeFe] hydrogenase with a selectively (57)Fe-labeled binuclear subsite is described. The precursor [(57)Fe2(adt)(CN)2(CO)4](2-) was synthesized from the (57)Fe metal, S8, CO, (NEt4)CN, NH4Cl, and CH2O. (Et4N)2[(57)Fe2(adt)(CN)2(CO)4] was then used for the maturation of the [FeFe] hydrogenase HydA1 from Chlamydomonas reinhardti...
