Thin films of nickel ferrocyanide are grown at nickel electrode surfaces by electrochemical oxidative treatment. This report describes some new microgravimetric, quartz crystal microbalance (QCM) experiments using isotopically substituted solvents which detail the transport of solvent during the redox process of the Fe sites. The results show that solvent incorporation accompanies cesium ion ex...

The ion size matters: the structures of corannulene monoanions crystallized with Cs(+) and Rb(+) ions in the presence of [18]crown-6 reveal the intrinsic binding preferences of alkali metals and allow evaluation of the bowl deformation caused by negative charge distribution and metal binding. The large cesium cation coordinates exclusively to the concave face of C(20) H(10)(-), whereas the smal...

Title of Dissertation: FABRICATION AND MEASUREMENT OF REGENERABLE LOW WORK FUNCTION DISPENSER PHOTOCATHODES Nathan A. Moody, Doctor of Philosophy, 2006 Dissertation Directed By: Professor & Chair, Patrick G. O’Shea Department of Electrical and Computer Engineering Laser-switched photoemitters are a source of electrons for high current applications such as free electron lasers. Laser-modulated p...

We propose a novel type of Rydberg dimer, consisting Rydberg-state atom bound to distant positive ion. The molecule is formed through long-range electric-multipole interaction between the and point-like present potential energy curves (PECs) that are asymptotically connected with $nP$- or $nD$-states rubidium cesium. PECs exhibit deep, wells which support many vibrational states Rydberg-atom-io...

Excitatory postsynaptic potentials (EPSP's) generated in crab muscle fibers by a single motor axon, differ in amplitude and facilitation. Some EPSP's are large at low frequencies of stimulation and show little facilitation; others are smaller and show pronounced facilitation. When K(+) is replaced by Cs(+) in the physiological solution, all EPSP's increase in amplitude, but small EPSP's increas...

The actions of mu- and delta-opioid agonists (DAMGO and DPDPE, respectively) on GABAergic interneurons in stratum oriens of area CA1 of the hippocampus were examined by using whole-cell voltage-clamp recordings in brain slices. Both agonists consistently generated outward currents of similar magnitude (15-20 pA) in the majority of cells. However, under control conditions, current-voltage (I/V) ...

In FEEP thrusters, field ionization of cesium occurs on the liquid metal surface at the outlet of a 1 μm slit. The main concern with this ionization mechanism is the possible clogging of the emitter slit due to oxidation of cesium. As an alkali metal, cesium reacts very rapidly with water, forming cesium hydroxide (CsOH), and with oxygen, forming cesium oxide (Cs2O). These compounds melt or dec...

Polyaniline titanotungstate (PATiW) was synthesized by the sol-gel method. Adsorption isotherm studies of Cs from aqueous solution are described. Elemental Composition, chemical solubility, ion-exchange capacity (IEC) and pH titration are studied. Distribution coefficients (Kd) for ten metal ions have been determined. It was found that the polyaniline titanotungstate has high affinity and high ...
