R.K. Singh Raman,R.K. Singh Raman,P. Chakraborty Banerjee,Derrek E. Lobo,Derrek E. Lobo,Hemtej Gullapalli,Madusha Sumandasa,Ashwin Kumar,Lokesh Choudhary,Rachel Tkacz,Rachel Tkacz,Pulickel M. Ajayan,Mainak Majumder,Mainak Majumder +13 more
TL;DR: Graphene coating on copper (Cu) is shown to increase the resistance of the metal to electrochemical degradation by one and half orders of magnitude as discussed by the authors, which can bring paradigm changes in the development of anti-corrosion coatings using conformal ultrathin graphene films.

Impedance Spectroscopy as a Tool for Chemical and Electrochemical Analysis of Mixed Conductors: A Case Study of Ceria
Wei Lai,Sossina M. Haile +1 more
TL;DR: In this paper, the AC impedance response of mixed ionic and electronic conductors (MIECs) is derived from first principles and quantitatively compared with experimental data, and a broad spectrum of electrical and thermodynamic properties is extracted solely from the measurement of impedance spectra over wide oxygen partial pressure and temperature ranges.

Effects of Nanoparticle Geometry and Size Distribution on Diffusion Impedance of Battery Electrodes
Juhyun Song,Martin Z. Bazant +1 more
TL;DR: In this article, the authors revisited bounded diffusion impedance models and incorporated them into an overall impedance model for different electrode configurations, and applied the theoretical models to experimental data of a silicon nanowire electrode to show the effects of including the actual nano-ire geometry and radius distribution in interpreting the impedance data.
