Ion Mobility Studies on the Negative Ion-Molecule Chemistry of Isoflurane and Enflurane

In the present work we present an investigation of the negative ion-molecule chemistry of the anaesthetics isoflurane, ISOF, and enflurane, ENF, in an ion mobility spectrometry/mass spectrometry (IMS/MS), in both air and nitrogen. Hexachloroethane (HCE) was introduced in both air and nitrogen to produce Cl- as a reactant ion. This study was undertaken owing to uncertainties in the chemical proc...

Negative ion chemistry in Titan’s upper atmosphere

The Electron Spectrometer (ELS), one of the sensors making up the Cassini Plasma Spectrometer (CAPS) revealed the existence of numerous negative ions in Titan’s upper atmosphere. The observations at closest approach ( 1000 km) show evidence for negatively charged ions up to 10,000 amu/q, as well as two distinct peaks at 2274 and 4478 amu/q, and maybe a third one at 82714 amu/q. We present the f...

Spectroscopic Studies on Titanium Ion Binding to the Apolactoferrin

Titanium (Ti) is a relatively abundant element that has found growing applications in medical science and recently some of Ti compounds are introduced as anticancer drugs. In spite of very limited data which exist on the Ti metabolism, some proteins might be involved in the mechanism of action of Ti. Up to our knowledge, there is not any report in the literature concerning binding of Ti to apol...
