Quantum chemical calculations based on DFT are employed to study the electronic structure and binding affinity of chelators used in the removal of iron sulphide scales. Three chelating agents, EDTA, HEDTA, and DTPA, are considered in this work. The complexes showed a coordination number of 5, ...
A series of Hofmann type clathrates with a general formula: M(NH3)2M′(CN)4·2G, where M ∈ {Ni, Mn, Cd}, M′ ∈ {Ni, Pd}, while G is benzene or thiophene, were prepared and their Raman and far-infrared spectra were recorded in the region 650–50 cm−1. The main bands of...
Give the balanced formula equation, complete ionic equation, and net ionic equation for the reaction between lead(II) nitrate and sodium acetate. Write the net ionic equation only for any precipitation reaction which forms when sodium sul...
Write the balanced molecular equation for the reaction that occurs between iron(III) chloride and silver nitrate. Give the complete ionic equation for the reaction (if any) that occurs when aqueous solutions of lithum sulfide and copper(II) nitrate are mixe...
2.2. Synthesis of Fe-Based MOF (MIL-101(Fe)) With some modifications, the Fe-based MOF MIL-101(Fe) was developed using a conventional solvothermal technique utilising the reported procedures. In the traditional solvothermal approach, and a solution of iron salt was made by sonicating 80 mL ...
Iron–sulphur (Fe–S) proteins are nearly ubiquitous across all domains of life and carry out many important cellular functions such as respiration, photosynthesis, nitrogen fixation and gene regulation (Beinert, 2000; Kiley and Beinert, 2003; Fontecave, 2006). In Escherichia coli, the majority ...
The enhancement in the selectivity of the reaction can be attributed to the synergic effects of iron (III) and 1-butanethiol. select article SHG and MDC spectroscopy of chiral organic monolayer at the air–water interface Research articleAbstract only SHG and MDC spectroscopy of chiral...
Finally, when the substrate of Atm1 is abundant, under iron-surplus conditions, a regulatory di-sulphide bond forms within another regulator, Yap5, which in turn activates a further subset of genes whose products sequester surplus iron (Ccc1 and Tyw1) plus GRX4 (Li et al., 2008; L. ...
