Constraining the point source parameters of the 11 November 2019 Mw 4.9 Le Teil earthquake using multiple relocation approaches, first motion and full waveform inversions

open access: yesComptes Rendus. Géoscience, 2021
The point source parameters of the 11 November 2019 Le Teil earthquake (Mw 4.9) in France are revisited. Previous hypocenter determinations either located it on the wrong side of the causative fault, or had to restrain the depth ranges to obtain ...

Description and Understanding of Complex Fault Block Reservoir Geology

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Reservoir description is an important step in oilfield development. Before mining, using various technical means to analyze and study oilfield structure can achieve the purpose of fully understanding the reservoir and provide theoretical basis for reservoir development.

4D Insights into Coral Biomineralization: Effects of Ocean Acidification on the Early Skeleton Development of a Stony Coral

open access: yesAdvanced Science, EarlyView.
Early coral skeletons grow through formation of two co‐joined zones, rapid accretion deposits and thickening deposits. Advanced imaging and simulations reveal that ocean acidification reshapes these zones, shifting the coral portfolio of mineral phases which alters skeletal resistance to mechanical stress.

Analysis of a travertine system controlled by the transpressional activity of the Alhama de Murcia fault: The Carraclaca site, eastern Betic Cordillera, Spain

open access: yesFrontiers in Earth Science, 2023
Continental carbonates, such as travertines and tufas, formed from CO2-rich groundwater degassing as it emerges at the Earth’s surface, are often associated with major crustal-scale faults.

Catalyst for Industrial‐Scale Seawater Electrolysis: Inhibit Active Metal Dissolution and Chlorine Corrosion

open access: yesAdvanced Science, EarlyView.
Alkaline seawater electrolysis represents a promising approach for sustainable green hydrogen production. Nevertheless, catalyst stability remains a critical challenge due to active metal dissolution and chlorine‐induced corrosion during prolonged industrial‐scale operation. Here, a surface engineering strategy is presented that employs phytic acid (PA)
