Ionic and covalent mixed-metal complexes by reaction of transition metal M H acids (M=Mo, Mn, Fe, Co) with [Ir(PMe 3 ) 4 CH 3 ] or [Rh(PMe 3 ) 3 CH 3 ] and structurally related Rh M and Ir M heterobimetallics (M=Mn, Fe, Ru)...
S K-edge XAS and DFT calculations on cytochrome P450: covalent and ionic contributions to the cysteine-Fe bond and their contribution to reactivity. E.I.: S K-edge XAS and DFT calculations on cytochrome P450: covalent and ionic contributions to the cysteine-Fe bond and their contribution to ...
1% yeast bacto-peptone and 2% glucose) on a rotary shaker at 150 rpm or in solid YPD medium containing 2% agar. Experiments were carried out at 28 °C. Yeast strains BY4741 (MATa; his3; leu2; met15; ura3), sod1Δ (MATa; his3; leu2; met15; ura3...
On the other hand, effective performance of Fe3O4@SiO2@NH2-TCT-Mel-PrBr as a result of thiosemicarbazide covalent binding of carbazide with IR absorption bands of 3177, 3264, and 3370 cm−1 due to the presence of the free NH2 group, also, the presence of C=S and C–N stretching ...
Then, the successively added Fe3+ cations in the suspension will absorb on the surface of CNTs through the negative functional groups due to the electrostatic interactions or covalent chemical bonding [20]. Next, EG coordinates with Fe3+ to become iron alkoxide, which can be decomposed to Fe3...
it is necessary to analyse the ionic composition of the amino acids on the surface of the catalysts (Fig. S2c, Table S3). One can see that proline is mainly present in protonated form. In contrast, serine and cysteine are present in almost equal proportions as the protonated and deprotonate...
Classify the compound N2F4 as ionic or covalent. What is the name of this compound? Name the following ionic compounds. a. BaS b. FeCl3 c. PbI4 d. SrBr2 I am writing out ionic compounds. The compound given is Fe2O3. I noticed on the periodic table iron had a c...
As an alternative energy, hydrogen can be converted into electrical energy via direct electrochemical conversion in fuel cells. One important drawback of full cells is the sluggish oxygen reduction reaction (ORR) promoted by the high-loading of platinum-group-metal (PGM) electrocatalysts. Fe-N-C ...
We have investigated the structural, optical band gap, and electrical properties of (Fe2O3)0.5x:(NiO)1 − 0.5x (x = 0.3, 0.4, 0.5, 0.6 and 0.7) epitaxial thin films grown on an atomically smooth substrate at room temperature. With increasing Fe2O3 content, the rock-salt ...
Compared with other chalcogenides (such as O and S), Se has a lower electronegativity and larger ionic radius. For cobalt, the outermost orbital electrons are less attractive to selenide; instead, weakly bound electrons are prone to redox reactions. However, the provision of electroactive sites ca...
