Geosciences, 2021 Volcanism is the most widespread expression of cyclic processes of formation and/or destruction that shape the Earth’s surface. Calderas are morphological depressions resulting from the collapse of a magma chamber following large eruptions and are ...

Carbon Energy, EarlyView.Heterostructured interfaces can accelerate hydrogen evolution by improving water dissociation, yet their underlying mechanisms remain unclear. This study combines in situ Raman spectroscopy and density functional theory to reveal how the RuO2/TiO2 interface promotes both water dissociation and hydrogen adsorption, providing new insights into the ...

Anomalous Pacific‐Antarctic Ridge Volcanism Precedes Glacial Termination 2
Geochemistry, Geophysics, Geosystems, 2018 We present results from a well‐dated sediment core on the Pacific‐Antarctic Ridge (PAR) that document a ∼15 cm thick layer of basaltic ash shards that precedes the penultimate deglaciation (Termination 2).

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process
Carbon Energy, EarlyView.Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Signatures of widespread Surtseyan volcanism at the northern Reykjanes ridge
Communications Earth & EnvironmentSubmarine explosive volcanism shapes seafloor morphology, impacts marine ecosystems, and poses risks to maritime infrastructure and coastal communities. However, its occurrences and drivers remain poorly constrained, especially for basaltic systems. Here

Remote Sensing and GIS Contribution to a Natural Hazard Database in Western Saudi Arabia
Geosciences, 2019 The most frequent disasters in Western Saudi Arabia are flash floods, earthquakes and volcanism, especially submarine volcanism potentially causing tsunamis in the Red Sea and submarine mass movements, dust storms and droughts.

Multiphase Tectonic Process With Slab Dynamics in the Northern East China Sea Shelf Basin
Geological Journal, EarlyView.Megasequence 1 characterised by Palaeocene extension and differential subsidence driven by the rollback of the subducting Izanagi Plate. Megasequence 2 records a kinematic reorganisation of the East Asian margin, transition from a rifting to a compressional regime.
