Introduction

Dongxia Liu is a prominent inventor based in Rochester, NY (US). He has made significant contributions to the field of ion-conducting ceramics, particularly through his innovative patents. With a total of 2 patents, Liu's work focuses on enhancing the performance of materials used in fuel cells and other electrochemical applications.

Latest Patents

Liu's latest patents include the "Ion-conducting ceramic apparatus, method, fabrication, and applications" and "Ion-/proton-conducting apparatus and method." Both patents describe a c-axis-oriented hydroxyapatite (HAP) thin film synthesized by seeded growth on a palladium hydrogen membrane substrate. The synthetic process involves electrochemical seeding on the substrate, followed by secondary and tertiary hydrothermal treatments that promote growth along the c-axes and a-axes in sequence. By adjusting the synthetic conditions, Liu's method allows for the growth of HAP thin films to a controllable thickness with dense coverage on the substrate. These thin films exhibit relatively high proton conductivity under hydrogen atmosphere and high-temperature conditions. The c-axis oriented films are designed for integration into fuel cells, particularly for applications in the intermediate temperature range of 200-600°C. Furthermore, the electrochemical-hydrothermal deposition technique can be utilized to create other oriented crystal materials with optimized properties, which are useful for separations, catalysis, electronic and electrochemical applications, electrochemical membrane reactors, and chemical sensors.
