Synergistic CO2 Removal via Enhanced Olivine Weathering and Diatom Growth in the Ocean

open access: yesOcean-Land-Atmosphere Research
Enhancing the alkalinity of the ocean is a promising approach for CO2 removal by promoting marine carbon sequestration. Olivine is a key candidate material for enhancing alkalinity owing to its release of silicates when dissolved in seawater.

Spectral Deconvolution Analysis of Mafic Mineral in Irregular Mare Patches on the Moon

open access: yesJournal of Astronomy and Space Sciences, 2022
Irregular mare patches (IMPs), recently discovered on the Moon, are eruptions of magma on the lunar surface, and their origins are still in question. While prior studies on IMPs have mainly focused on optical image analysis, in this study, an analysis ...

Impurity Tolerance in LiFePO4 Cathodes: Contrasting Structural, Electronic, and Electrochemical Roles of Residual Ni and Cr

open access: yesAdvanced Science, EarlyView.
Impurity tolerance in LiFePO4 cathodes varies strongly with impurity type and content. Low Ni levels are accommodated within the lattice with minimal structural disruption, whereas higher Ni contents introduce antisite disorder. In contrast, Cr impurities segregate from the LiFePO4 framework, blocking lithium‐ion pathways and leading to inferior ...
