Non-metallic electronic regulation in CuCo oxy-/thio-spinel as OER electrocatalysts
Researchers successfully prepared oxy-spinel of Cu1-xCo2+xO4 nanaoflakes and thio-spinel of Cu1-xCo2+xS4 nanospheres by a facile hydrothermal method. The resulting Cu1-xCo2+xO4 exhibits higher catalytic performances toward OER in alkaline media than Cu1-xCo2+xS4 for water oxidation. Experimentally and theoretically, the superior OER catalytic activity of Cu1-xCo2+xO4 nanoflakes mainly depends on the strongly-electronegativity of oxygen element in spinel structure, which determines the higher valence state of Co active sites in CuCo oxyspinel.

Reawakened geyser does not foretell Yellowstone volcanic eruptions, study shows
Geyser eruptions, like volcanic eruptions, are a mystery, so the reactivation of Steamboat Geyser in Yellowstone in 2018 provided an opportunity to explore why geysers turn off and on, and what determines their periodicity. A team led by UC Berkeley researchers found little evidence of magma moving below the geyser, meaning no sign of imminent hydrothermal eruptions, but did discover a relationship between the height of the column and the depth of the water reservoir.
