通常,反应性•OH在溶液中不是完全游离的,而是结合在某种络合物中,这取决于所用螯合剂的类型(螯合•OH)。[12-14]然而,Bray-Gorin机制涉及双电子转移和随后形成的高价Fe(IV)=O(铁基)中间体:Fe2+ + H2O2→[Fe(IV)=O]2+ ...
metallireducens senses when soluble electron acceptors are depleted and then synthesizes the appropriate appendages to permit it to search for, and establish contact with, insoluble Fe(iii) or Mn(iv) oxide. This approach to the use of an insoluble electron acceptor may explain why Geobacter ...

Models for the quantitative determination of Fe, Nb and Si in titanium (IV) oxide white pigments by flame atomic absorption spectrometry (AAS) are described. For the models two multivariate linear calibration techniques have been used: principal component regression (PCR) and partial least squares ...

Crystal structures of iron oxide (a-Fe20 3) and oxyhydroxides (d,y-FeOOH) (after Kwon et a1.,2007) 水溶液中污染物的相互作用力也是决定羟基氧化铁 去污能力 的一个重要原因 ,其去污能力 可由污染物 在不同 pH 值下的溶解性 与金属氧化物羟基氧化铁 的表面电荷特性决定(魏俊峰等,2000) 。
Similar thicknesses of FeGa were also deposited on thermally oxidized Si substrates with an oxide layer of 500 nm. This was performed to understand the magnetic properties of the FeGa thin films due to the alloy itself and not due to the stress effects. The in-plane hysteresis loops of ...
Dissimilatory metal-reducing bacteria (DMRB) can utilize Fe(III) associated with aqueous complexes or solid phases, such as oxide and oxyhydroxide minerals, as a terminal electron acceptor coupled to the oxidation of H 2 or organic substrates. These bacteria are also capable of reducing other metal...
(ESR) and the corresponding control ROS-trapping experiments were performed to identify the potential PROS generated55. The characteristic peaks of 5,5-dimethyl-1-pyrroline N-oxide (DMPO)-O2•−are observed from both ESR spectra taken in the presence of FePc@2D-Cu–N–C and 2D-FeCu–N...
