Reducing iridium loading in oxygen evolution reaction electrocatalysts using core–shell particles with nitride cores
The oxygen evolution reaction (OER) has broad applications in electrochemical devices, but
it often requires expensive and scarce Ir-based catalysts in acid electrolyte. Presented here …

Dominance of felsic continental crust on Earth after 3 billion years ago is recorded by vanadium isotopes
The transition from mafic to felsic upper continental crust (UCC) is crucial to habitability of
Earth, and may be related to the onset of plate tectonics. Thus, defining when this crustal …

High resolution osmium data record three distinct pulses of magmatic activity during cretaceous Oceanic Anoxic Event 2 (OAE-2)
Abstract Oceanic Anoxic Event 2 (OAE-2) occurred at the Cenomanian-Turonian boundary
(∼ 94.1 Ma) and was a time of profound global changes in ocean chemistry and the carbon …
