A perfect couple: Chromium keeps ruthenium grounded in water electrolysis
They say opposites attract, and many couples do fit this pattern. One is pragmatic and down-to-earth, while the other is a dreamer with their head in the clouds. Yet, these differences make them perfect for each other. According to researchers at ICFO, chemical interactions
