Application of crystal field theory to the infrared spectra of transition metal complexes
… IR spectra of 8-quinolinol chelqtes of di~ and trivalent metals of the first transition series. The metal-sensitivity of bands in the IR spectra of structura~ly differing substituted 8-quinolinol Qhelates ~eceives an interpretation in terms of crystal field theory. The effect of halogen and …

Layered Double Hydroxides and the Origins of Life on Earth
… where M(II) and M(III) are any divalent and trivalent metals, respectively. Y can be nearly any anion, although modern naturally occuring LDH systems incorporate carbonate (CO32-), chloride (Cl-), or sulfate (SO42-) anions. Intercalated cobalticyanide anion shows a small yet observable …

Ligand field considerations for the reactivity of high valent metal-oxo complexes and of bimetallic HX splitting photocatalysts
… tris(alkoxide) complexes of divalent and trivalent metals were synthesized and characterized as single metal site models of oxidic metal clusters. Via oxygen atom transfer reactions, d⁰, d¹, and d² early transition metal-oxo complexes were stabilized. Analysis of structural parameters, …

Investigating the Role of Various Environment and Process Conditions in Wastewater Sludge Odor Generation
… the labile proteins was observed to decrease. Trivalent metals are found to play an important role in binding of labile proteins thus effecting odor potential contained in sludge/biosolids. This was found true for most sludge irrespective of their liming status and independent of upstream …

Polar intermetallic compounds of the silicon and arsenic family elements and their ternary hydrides and fluorides
… Bi; Tt = Si, Ge, Sn, Pb and Z = H, F. Several trivalent rare-earth-metal pnictides, RE5Pn3 (RE = Y, La, Gd, Tb, Dy, Ho, Er, Tm) and alkaline-earth-metal trielides, A5Tr3Zx (Tr = Ga, In, Tl) have been included in an effort to complete observed structural trends. Two main experimental techniques …

Anaerobic Digestion: Factors Effecting Odor Generation
… part of this study has looked at the role of metals, iron and aluminum in particular, in determining the odor causing processes. The results showed that iron correlated well with headspace organic sulfur odor. In general, as the iron content of sludge increased greater amounts of odorous …
