A series of transition and post-transition metal ion (Mn, Cu, Zn, Pb, Bi) binary borate glasses was studied with special consideration the cations impact on structure, cross-linking capacity, more generally, structure-property correlations. Infrared (IR) Raman spectroscopies were used for structural characterization. These complementary techniques are sensitive to short-range order as in differentiation tetrahedral trigonal units or regarding number non-bridging oxygen ions per unit....
Asymmetrical Pacman dinuclear Co bisporphyrin shows significantly improved activity and selectivity for catalytic reduction of O<sub>2</sub> to water in comparison with corresponding mononuclear porphyrins symmetrical bisporphyrins.
Co corroles containing electron-donating <italic>trans</italic> axial ligands are more active than those electron-withdrawing in catalyzing water oxidation.
Selective visible-light-driven O2 reduction to H2O2 was realized using BODIPY photosensitizers (PS) in the presence of ferrocene (Fc) as reductant and acetic acid proton source. Mechanistic studies suggested that could be activated by 3PS* through an energy transfer pathway give singlet oxygen (1O2) absence Fc. However, with Fc, first reductively quenched PS˙-, which able reduce superoxide radical form a subsequent electron step.
The synthesis and characterization of several electron-poor iron(II) porphyrin (FeTFPPBr8) complexes with axial imidazole ligands are reported. single-crystal X-ray structures have been studied by a combination crystal packing Hirshfeld surface calculations, which explained the unusual axial-ligand geometries, e.g., strong tilt Fe-NIm bonds planes. six-coordinate [Fe(TFPPBr8)(1-MeIm)2] was multiple-temperature solid-state Mössbauer spectroscopy, suggested that it is low-spin complex δ ∼...
A new sterically hindered "picket fence-like" porphyrin with chelates for the second metal atom, H2TImPP (TImPP = meso-tetrakis[α,α,α,α-o-(5-imidazolecarboxylaminophenyl)]porphyrinato), is developed and used in synthesis of four iron(II) bis(imidazole) derivatives, which are characterized by single crystal X-ray other spectroscopies. The comprehensive studies on structures revealed noteworthy features including axial ligand arrangements, deformed planes, strongly tilted pickets can be...
High pressure structural phase transition of monoclinic paraotwayite type α -Ni(OH) 2 nanowires with a diameter 15 nm–20 nm and length several micrometers were studied by synchrotron x-ray diffraction (XRD) Raman spectra. It is found that the experience an isostructural associated amorphization H-sublattice hydroxide in interlayer spaces two-dimensional crystal structure at 6.3 GPa–9.3 GPa. We suggest can be attributed to H-sublattice. The bulk moduli for low high are 41.2 (4.2) GPa 94.4...
Cytochrome c oxidase (CcO) has a binuclear active site composed of high-spin heme group and tris-histidine-ligated copper ion (CuB). By using two different porphyrin models derived by Gunter (H2TPyPP) us (H2TImPP), we have isolated several mono- complexes including one carbonyl three chloride derivatives which are determined 100 K single-crystal X-ray. Low-temperature (4 K) EPR multitemperature (295–25 Mössbauer investigations on the products not only confirmed spin states metal ions (S =...
Abstract The increasing automobile repair industries (ARIs) with spray facilities have become an important volatile organic compounds (VOCs) pollution source in China. However, the VOCs health risk assessment for long-term exposure ARIs not been well characterized. In this study, though sampled from 51 typical Beijing, relationship between emission patterns, average daily concentrations (EC) and risks were comprehensively analyzed method. Results showed that of 117 samples ranged 68.53 to...
Summary Long-term problems are popular in various numerical simulations for understanding physical phenomena. However, conventional symplectic integration method can only handle a relatively small travel time and would exhibit very strong artifacts the presence of long duration, which greatly pollute modeling results. We employ inverse dispersion transform to reduce these accuracy is significantly improved, especially those times. use as post processing method, seems aggravate computational...
Metalloporphyrin complexes containing an additional imidazole ligand can provide information about the effect of deprotonation or hydrogen bonding on axial histidine unit in heme proteins.
