Plutonium (IV) Quantification in Technologically Relevant Media Using Potentiometric Sensor Array

Reactive electron scattering from biomolecules and technologically relevant molecules

Negative ion formation through dissociative electron attachment to the gas-phasevolatile anaesthetics enflurane and isoflurane (C3H2ClF5O) and to two chlorinated ethanes,pentachloroethane (C2HCl5) and hexachloroethane (C2Cl6), have been studied in a crossedelectron-molecular beam two sector field mass spectrometer experiment. Anion efficiencycurves for the negatively charged...

Potentiometric sensing array for monitoring aquatic systems.

Since aquatic environments are highly heterogeneous and dynamic, there is the need in aquatic ecosystem monitoring to replace traditional approaches based on periodical sampling followed by laboratory analysis with new automated techniques that allow one to obtain monitoring data with high spatial and temporal resolution. We report here on a potentiometric sensing array based on polymeric membr...

Potentiometric Determination of Cationic Surfactant using ‘Polymeric- Inorganic’ Nanocomposite Sensor

A cationic surfactant-selective electrode for sensitive analysis of cationic surfactant has been developed by using a plasticized poly (vinyl chloride) membrane based on nanocomposite cation exchanger polypyrrole zirconium titanium phosphate. The electrode is excellently selective for the cetyl trimethyl ammonium bromide (CTAB) ion over inorganic ions and other cationic surfactants. The membran...

A Structurally Characterized Organometallic Plutonium(IV) Complex

The blood-red plutonocene complex Pu(1,3-COT'')(1,4-COT'') (4; COT''=η8 -bis(trimethylsilyl)cyclooctatetraenyl) has been synthesized by oxidation of the anionic sandwich complex Li[Pu(1,4-COT'')2 ] (3) with anhydrous cobalt(II) chloride. The first crystal structure determination of an organoplutonium(IV) complex revealed an asymmetric sandwich structure for 4 where one COT'' ring is 1,3-substit...
