Crystallization of MAPbI3 is driven by halide chemistry: MAI iodine attacks lead ions and causes subsequent breaking PbI2.

Highly stable organic solids, based on van der Waals interactions between cylindrical porphyrinwires, exhibit unique square iodine-channels (10 × 10 Å) and exceptionally hollow porphyrinwires. The functionalized iodine-cavities could be capable of conferring specific adsorption behavior for mercury and lead ions, whereas hollow porphyrinwires might serve as a model for the development of hybrid...

there has been a considerable interest in platinum group metal complexes of thiaoxa-donor macrocycles because of their unusual properties. 1 As an extension of our studies involving mixed-donor cyclic 2a and acyclic 2b ligands incorporating thiaoxa mixed-donors, we became interested in exploring their coordination chemistry of platinum group metal ions. The S2O-donor macrocycle of the title com...

The aim of this study was to evaluate the behavior of high-noble gold-platinum alloy samples (18 + 8 Rafinerija plemenitih kovina, Zagreb, Hrvatska), in a phosphate buffer pH 6.0. The aim of the study was to determine the type and amount of released metal ions from the alloy, and to evaluate how the time of exposure to the phosphate buffer pH 6.0 influences the release of metal ions from the al...

Platinum-cored ferritins were synthesized as electrocatalysts by electrochemical biomineralization of immobilized apoferritin with platinum. The platinum cored ferritin was fabricated by exposing the immobilized apoferritin to platinum ions at a reduction potential. On the platinum-cored ferritin, oxygen is reduced to water with four protons and four electrons generated from the anode. The ferr...

In this work, the cation and anion products of the reactions between platinum clusters produced by laser ablation and the benzene molecules seeded in argon have been studied using a high-resolution reflectron time-of-flight mass spectrometer (RTOFMS). The dominant cation products are [C(6n)H(6n - k)](+) and [Pt(m)(C(6)H(6))(n)](+) complexes, while the dominant anion products are dehydrogenated ...

A G-quadruplex-based luminescent platinum(II) switch-on probe has been developed for the selective detection of nanomolar Ag(+) ions in aqueous solution.

Concentrations of inorganic ions (Cl , H + , SO4 2, NO3 , NH4 + , Na + , K + , Ca 2+ , Mg 2+ ) and metals (V, Ni, Cu, Pb, Cr Mn, Al, Fe) in bulk precipitation and PM10 samples collected in the metropolitan area of Costa Rica were analyzed. Good correlations between acidity in bulk precipitation with the concentrations of aerosols in the air were observed. The scavenging of the pollutants from t...

In this article electrochemical determination of captopril at the surface of the platinum coated nanoporous gold film (PtNPGF) electrode is reported using the cyclic voltammetry and amperometry. For the preparation of PtNPGF, the surface of NPGF electrode was covered with Cu layer using underpotential electrochemical deposition (UPD).Afterward, the copper layer is replaced with platinum ions vi...
