  • The functionalization of an array of eight, closely spaced ({approximately}1.2 {mu}m) Pt or Au microelectrodes each {approximately}50 {mu}m long, 2 {mu}m wide, and 0.1 {mu}m thick with redox-active WO{sub 3} and polyaniline and the electrochemical characterization of the WO{sub 3}/polyaniline junction are reported. Chips consisting of microfabricated WO{sub 3} covering three of the available eight microelectrodes have been analyzed by Auger electron spectroscopy. The remaining five microelectrodes are available for further derivatization with polyaniline or can function as counterelectrodes. By placing a counterelectrode and a Ag quasi-reference electrode directly on the microchip and by coating the assembly with a thinmore » film of poly(vinyl alcohol)/H{sub 3}PO{sub 4} solid polymeric electrolyte, the electrochemical system becomes self-contained. The solid polymer electrolyte is a good room-temperature H{sup +} conductor only when exposed to a H{sub 2}O-containing atmosphere. Complex impedance studies show as much as a 10{sup 3} change in H{sup +} conductivity from H{sub 2}O-saturated to H{sub 2}O-free gaseous atmosphere above the polymer electrolyte. The changes in conductivity of WO{sub 3} upon reduction or polyaniline upon oxidation allow demonstration of solid-state microelectrochemical transistors with these materials. The combination of WO{sub 3} and polyaniline on the chip allows demonstration of a microelectrochemical diode.« less
  • Molecular-level understanding of electrochemical processes occurring at electrode-electrolyte interfaces (EEI) is key to the rational development of high-performance and sustainable electrochemical technologies. This article reports the development and first application of solid-state in situ electrochemical probes to study redox and catalytic processes occurring at well-defined EEI generated using soft-landing of mass- and charge-selected cluster ions (SL). In situ electrochemical probes with excellent mass transfer properties are fabricated using carefully-designed nanoporous ionic liquid membranes. SL enables deposition of pure active species that are not obtainable with other techniques onto electrode surfaces with precise control over charge state, composition, and kinetic energy.more » SL is, therefore, a unique tool for studying fundamental processes occurring at EEI. For the first time using an aprotic electrochemical probe, the effect of charge state (PMo12O403-/2-) and the contribution of building blocks of Keggin polyoxometalate (POM) clusters to redox processes are characterized by populating EEI with novel POM anions generated by electrospray ionization and gas phase dissociation. Additionally, a proton conducting electrochemical probe has been developed to characterize the reactive electrochemistry (oxygen reduction activity) of bare Pt clusters (Pt40 ~1 nm diameter), thus demonstrating the capability of the probe for studying reactions in controlled gaseous environments. The newly developed in situ electrochemical probes combined with ion SL provide a versatile method to characterize the EEI in solid-state redox systems and reactive electrochemistry at precisely-defined conditions. This capability will advance molecular-level understanding of processes occurring at EEI that are critical to many energy-related technologies.« less
  • (Ce{sub 0.83}Sm{sub 0.17}){sub 1{minus}x}Ln{sub x}O{sub 2{minus}{delta}} (Ln = Pr, Tb, 0 {le} x {le} 0.1) solid electrolytes were prepared by a soft hydrothermal method at 260 C. Transmission electron microscopy (TEM) and X-ray diffraction were used to clarify the structure and morphologies of the crystalline powers. The average crystallite size observed in the TEM is in the range of 10--60 nm, close to those calculated by the Scherrer formula from X-ray patterns. The uniformly small particle size of the hydrothermally prepared materials allows sintering of the samples into highly dense ceramic pellets at 1,300--1,400 C, a significantly lower temperature, comparedmore » to that of 1,600--1,650 C required for samples prepared by solid-state techniques. The variation of the electrical conductivity with the partial pressure of oxygen, Po{sub 2}, in the range 0.21 to 10{sup {minus}24} atm at various temperatures was used to determine the electrolytic domain boundary (EDB) of (Ce{sub 0.83}Sm{sub 0.17}){sub 1{minus}x}(Tb/Pr){sub x}O{sub 2{minus}{delta}} for 0 {le} x {le} 0.1. The EDB of Ce{sub 0.83}Sm{sub 0.17}O{sub 2{minus}{delta}} is {approximately}10{sup {minus}18} atm at 700 C. It is shown that neither Pr nor Tb doping has a significant effect on the EDB of Ce{sub 0.83}Sm{sub 0.17}O{sub 2{minus}{delta}}.« less
