Was the Kalkarindji Continental Flood Basalt Province a Driver of Environmental Change at the Dawn of the Phanerozoic?

open access: yesGeophysical Monograph Series, Page 435-447., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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.

High precision measurement of trace F and Cl in olivine by electron probe microanalysis

open access: yesProgress in Earth and Planetary Science, 2023
Fluorine (F) and chlorine (Cl) are important volatiles in olivine and its high-pressure polymorphs, which would significantly affect olivine phase transition, melting temperature, and physical property of the mantle.

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 ...

10 Years Development of Potassium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of

Glass in the submarine section of the HSDP2 drill core, Hilo, Hawaii [PDF]

open access: yes, 2004
The Hawaii Scientific Drilling Project recovered ~3 km of basalt by coring into the flank of Mauna Kea volcano at Hilo, Hawaii. Rocks recovered from deeper than ~1 km were deposited below sea level and contain considerable fresh glass. We report electron

A Perspective on Pathways Toward Commercial Sodium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Comprehensive analysis of the existing and prospective sodium‐ion battery (SIB) systems unveils that a wider application of SIBs should primarily focus on i) regulating the composition, morphology, surface chemistry, safety performance, and production feasibility of mainstream cathodes, ii) enhancing the high‐voltage stability, film formation ability ...

Olivine or Impact Melt: Nature of the "Orange" Material on Vesta from Dawn

open access: yes, 2013
NASA's Dawn mission observed a great variety of colored terrains on asteroid (4) Vesta during its survey with the Framing Camera (FC). Here we present a detailed study of the orange material on Vesta, which was first observed in color ratio images ...

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

open access: yesAdvanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Comparative Advances in Sulfide and Halide Electrolytes for Commercialization of All‐Solid‐State Lithium Batteries

open access: yesAdvanced Materials, EarlyView.
This review compares sulfide‐ and halide‐based solid electrolytes for all‐solid‐state lithium batteries (ASSBs), highlighting their ionic conductivity, chemical stability, manufacturability, and compatibility with lithium metal. Sulfides offer higher conductivity, while halides provide enhanced stability and scalability.
