Solid-state superionic conductors for advanced nanoscale fabrication
… AgIAgPO3 was chosen as an ideal candidate solid ionic conductor because it is optically transparent, has a high ionic conductivity for silver at room temperature, and most importantly it has a remarkably low glass transition temperature which facilitates low temperature thermal nanoscale molding. …

Ab initio investigations of solid electrolytes for lithium- and Sodium-ion batteries
… the structural origins of high conductivity in ionic conductor materials and provides a thermodynamic explanation of why the integration of these newly developed thiophosphates into high-rate cells has proven difficult in practice, often resulting in high interfacial resistance. As a result of …

Electronic, magnetic and thermal properties of Pb₂₋x AxCrO₅ (A = K or La)
… further, above 450 K the sample becomes an ionic conductor. As temperature increases a decrease in resistance is observed in the lanthanum/potassium doped samples. Using Differential Scanning Calorimetry experiment an endothermic peak is observed for the Pb2Cr05 and lanthanum/potassium doped …

A microfabricated solid oxide fuel cell
… the electrochemical oxidation of fuel through an ionic conductor. Oxide ions permeate across a ceramic electrolyte membrane to react with the fuel, driving electrons back around through the load. The focus of this work is to analyze the behavior of these membranes to prevent failure as the device …

Untersuchung der gassensitiven Eigenschaften von SnO2/NASICON-Kompositen
… for the first time. NASICON (NAtrium, Super Ionic CONductor, Na(1+x)Zr2SixP(3-x)O12; 0 <= x <= 3) was used as a model for solid electrolyte additives. The structure of that material is ideally suitable for studies of the correlation between material parameters and the gas sensitivity of …

Solid state electrochemical processes for nanofabrication
… using an AFM probe as the working electrode and ionically conductive glass (AgI)0.25(AgPO3)0.75 as the solid electrolyte in an electrochemical cell configuration. While the tip based approach was primarily adapted to explore time-scale and resolution capabilities with probe based writing, erasing …

TIMELESS QUESTIONS AND MODERN CHALLENGES: A JOURNEY FROM THE ORIGIN OF LIFE IN HYDROTHERMAL VENTS TO ELECTROCHEMICAL CO2 REDUCTION
… simultaneously functions as an electronic conductor, ionic conductor, and electrocatalyst, and exploits a pH gradient to drive the coupling of CO2 reduction (CO2R) and hydrogen oxidation (HOR)—offers a conceptual framework that could be translated into industrial processes, such as the …
