The amorphous compound [Mg(H2dhtp)(H2O)2] 1′ was shown to be a highly efficient and reusable luminescent sensor for the detection of water in THF, due to its transformation to the strongly emissive complex [Mg(H2dhtp)(H2O)5]·H2O 1.

Abstract Mössbauer spectroscopy has been used to analyze the rust layers formed on a weathering steel and a 1010 steel exposed for 10-1/2 months to an urban-industrial atmosphere. No significant difference was found comparing the rusts of both steels: they were composed by γ-FeOOH, superparamagnetic α-FeOOH, and an amorphous or gel-like compound. γ-FeOOH is more abundant in the internal rust layers, whereas the amount of α-FeOOH and the amorphous compound increase in the external rusts. Part of the samples received an initial copper deposit by immersion of the steel plates in a CuSO4 bath. Mössbauer spectroscopy analysis showed that the amorphous substance was no longer present in the rusts of those specimens; that is, the rusts of both steels were formed only by γ-FeOOH and α-FeOOH.

AbstractSeveral iron phosphates were synthesized by solution-based techniques and tested as cathodes in non aqueous lithium cells. The addition of phosphate ions to a solution of iron (II) produced crystalline Fe3(PO4)2. This material is easily oxidized by air to form an amorphous phase that is able to reversibly intercalate lithium. The amorphous compound was identified to be a mixture of FePO4 and Fe2O3. A new synthetic route was developed to prepare pure amorphous FePO4. Amorphous LiFePO4 was obtained by chemical lithiation of FePO4. The material was heated at 500°C under reducing atmosphere to obtain nano-crystalline LiFePO4. This latter material showed excellent electrochemical performance when used as cathode of lithium cells.

Phytoestrogens are secondary plant metabolites produced by plants that are similar in structure of estrogen. Human consumption of these compounds has been associated with many health benefits. In this study, we investigated the potential phytoestrogen content of dietary Momordica charantia Linn. (Bitter melon) seeds were collected from the Hyderabad-Karnataka regions of India. A phenolic dietary phytoestrogen has been isolated from the crude ethanol extract of Bitter melon seeds. After preparative HPLC whitish amorphous compound was yielded. The HPLC purified compound is subjected to spectral analysis using IR, NMR and MS. The spectral data revealed that the phenolphthalein a phytoestrogenic molecule is present in the ethanol extract of dietary Bitter melon seeds.
