High-power Na-ion batteries have tremendous potential in various large-scale applications. However, conventional charge storage through ion intercalation or double-layer formation cannot satisfy the requirements of such applications owing to the slow kinetics of ion intercalation and the small capacitance of the double layer. The present work demonstrates that the pseudocapacitance of the nanos...

Beams of short-lived radioactive nuclei are needed for frontier experimental research in nuclear structure, reactions, and astrophysics. Negatively charged radioactive ion beams have unique advantages and allow for the use of a tandem accelerator for post-acceleration, which can provide the highest beamquality and continuously variable energies. Negative ion beams can be obtainedwith high inten...

Electron attachment to perfluoromethylcyclohexane (C7F14) and sulfur hexafluoride (SF6) is studied in a Q machine which produces a thermally ionized potassium plasma at an electron temperature Te approximately = 0.2 eV (2300 K) . Negative ion formation is observed by Langmuir probe measurements of the reduction in electron density as electrons attach to C7F14 to form C7F14- or to SF6 to produce...

Title of Dissertation: A GAS-INJECTION NEGATIVE ION SOURCE FOR ACCELERATOR MASS SPECTROMETRY Scott Joseph Tumey, Doctor of Philosophy, 2004 Dissertation directed by: Professor Alice C. Mignerey Department of Chemistry & Biochemistry Accelerator mass spectrometry is an ultra-sensitive isotopic analysis technique that allows for the determination of rare long-lived radionuclides such as radiocarb...

use of wastewater treatment methods in aquaculture is one of the main ways for decreasing the environmental effects of this industry and applies the best management practices (bmps). anionic compounds are the main pollutants in recirculation aquaculture systems. ion exchangers such as clays are vastly applied in waste water industry but in aquaculture systems at yet there isn't any report ...

The purpose of the work presented here was to evaluate the influence of solution composition and analyte characteristics on responsiveness to analysis with negative ion electrospray ionization mass spectrometry. The responses of a series of structurally diverse acidic molecules were compared in various solvents. Response was generally observed to be higher in methanol than acetonitrile and resp...

We report systematic investigation of duplex DNA complexes with minor groove binders (Hoechst 33258, Hoechst 33342, Netropsin and DAPI) and intercalators (daunomycin, doxorubicin, actinomycin D, ethidium, cryptolepine, neocryptolepine, m-Amsacrine, proflavine, ellipticine and mitoxantrone) by ESI-MS and ESI-MS/MS in the negative ion mode and in the positive ion mode. The apparent solution phase...
