Advanced Energy and Sustainability Research, Volume 6, Issue 4, April 2025.This study investigates the electrical properties of bimetallic Mn‐Co BTC MOFs with varying Mn/Co ratios. The findings reveal that charge transport in these MOFs primarily occurs via hopping at lower frequencies, transitioning to lattice response at higher frequencies. The study also demonstrates the correlation between AC conductivity and OER activity.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1986 Spheroidal graphite cast irons with both (a) as a perfectly cast pearlitic matrix structure and (b) as a predominantly ferritic matrix structure were austenitized, oil-quenched and tempered to the same hardness level. After heat treatment (a) is considered to have graphites compressed by the matrix, and (b) is considered to have graphites existing more
