Abstract A high-efficient and stable catalyst is highly desired to catalyze ozone for refractory organic pollutants removal. In this work, Mn-Ce bimetallic oxide loaded CNT@Fe 3 C (Mn 0.7 Ce 0.3 O x /CNT@Fe C) was synthesized with Mn as the active component magnetic support. The catalytic performance of towards ozonation evaluated. TOC removal efficiency phenol degradation after 45 min reaction...

Metal accumulation in seeds is a prerequisite for germination and establishment of plants but also for micronutrient delivery to humans. To investigate metal transport processes and their interactions in seeds, we focused on METAL TOLERANCE PROTEIN8 (MTP8), a tonoplast transporter of the manganese (Mn) subclade of cation diffusion facilitators, which in Arabidopsis (Arabidopsis thaliana) is exp...

The divalent transition-metal cations Fe, Co, and Ni were used to test the hypothesis that Mn ions pass through calcium channels because Mn ions have a relatively low energy of hydration. The test ions were applied to the bath and comparisons were made of their effects on Ca or Mn spikes elicited from myoepithelial cells of the proventriculus of the polychaete worm Syllis spongiphila. Control e...

We present high-resolution UES spectra of the quasar PHL 957 obtained for studying the foreground Damped Lyα galaxy at z=2.309. Measurements of absorption lines lead to accurate abundance determinations of Fe, S and N which complement measurements of Zn, Cr and Ni already available for this system. We find [Fe/H]=−2.0± 0.1, [S/H]=−1.54± 0.06 and [N/H]=−2.76± 0.07. The ratio [Fe/Zn]=−0.44 provid...

7 -+ E transformation behavior in a Fe-21Mn alloy with different grain size and a Fe-32Mn-6Si alloy with various degrees of wld rolling is investigated and correlated with damping capacity. Effect of microstructure on damping capacity is discussed on the assumption that the capacity is proportional to volume swept by 7 / e boundaries. 1.INTRODUCTION Fe-Mn based alloys have been well known for s...

We studied the spin arrangement in ultrathin antiferromagnetic Mn films in contact with a ferromagnetic Fe(001) substrate using spin-polarized scanning tunneling microscopy. Mn shows a layerwise antiferromagnetic order on Fe(001). In regions where Mn overgrows Fe steps, a frustration of the antiferromagnetic order occurs which is similar to a 180 degrees domain wall. This topologically enforced...

The trend of [Mn/Fe] in the Galactic bulge follows the solar-neighborhood relation, but most stars in the Sagittarius dwarf spheroidal galaxy (Sgr dSph) show [Mn/Fe] deficient by ∼0.2 dex. This leads us to conclude that the Mn yields from both type Ia and type II SNe are metallicity-dependent. Our observations militate against the idea, suggested by Gratton, that Mn is over-produced by type Ia ...

In the oxido-centered title compound, [Fe(2)Mn(C(2)HCl(2)O(2))(6)O(C(4)H(8)O)(H(2)O)(2)], the central O atom is linked to three metal atoms, which are themselves each linked to four dichloro-acetate anions, and is in a triangular configuration. Two of the metal atoms are each coordinated by a water mol-ecule, whereas the third is coordinated by a tetra-hydro-furan mol-ecule. In the crystal, adj...

The influence of Mn addition on fatigue properties ferritic steel containing solute carbon was examined using rotating bending tests water-quenched Fe–0.016C–1.9Mn ferrite–pearlite 0.0035 mass% in comparison with Fe–C steels 0.0063–0.017 carbon. were carried out at ambient temperature around 300 K and a frequency 50 Hz stress ratio −1. Fe–C–Mn exhibited comparable hardness limit to the Fe–0.017...

in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4...
