AI Article Synopsis

  • The study focused on creating Co/nano-CeO composite layers using an electro-codeposition method with cobalt and dispersed CeO nanoparticles.
  • The performances of Co/nano-CeO layers were compared to pure Co layers through sliding friction tests in a biological lubricant solution, assessing their tribocorrosion characteristics.
  • Results indicated that the presence of nano-CeO particles in the cobalt matrix decreased friction coefficient and wear, while also enhancing corrosion resistance by improving polarization resistance and shifting the open circuit potential.

Article Abstract

Co/nano-CeO composite layers were developed by electro-codeposition method from a cobalt electrolyte containing dispersed CeO nanoparticles. The tribocorrosion performances of both Co/nano-CeO and pure Co layers were comparatively investigated by sliding friction tests under lubricated condition in biological Hank solution. The effect of embedded nano-CeO on the corrosion electrochemical response, friction coefficient and wear loss volume is analyzed. The results show that the codeposited of nano-CeO particles into cobalt matrix reduce the friction coefficient and wear weight loss as well as the shift of open circuit potential to active state, increasing the polarization resistance and reducing the corrosion damages.

The development of Pd-based materials with high activity and long-term stability is crucial for their practical applications as an anode catalyst in direct formic acid fuel cells. Herein, we reveal that the catalytic activity of Pd towards formic acid oxidation can be enhanced by incorporation of a series of rare-earth oxides, including ScO, CeO, LaO, and PrO. For example, Pd nanoparticles incorporated with ScO supported on nitrogen-doped reduced graphene oxide (Pd-ScO/N-rGO-, = 1/3, 1/2, 2/3, 1, and 3/2; "" denotes the molar ratio of Pd : Sc) can be obtained using a sodium borohydride reduction method.

Myocardial infarction (MI) is a leading cause of morbidity and mortality worldwide, and mitigating oxidative stress is crucial in managing MI. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a critical role in combating oxidative stress and facilitating cardiac remodeling post-MI. Here, we engineered Cerium oxide (CeO) nanoparticle-guided assemblies of ceria/Nrf2 nanocomposites to deliver Nrf2 plasmids.
