Steric Coordination Modulated Iodine Chemistry With Four‐Electron Conversion for Zinc‐Iodine Batteries

open access: yesAdvanced Materials, EarlyView.
A dual‐additive electrolyte strategy is developed to address the hydrolysis of I+ in the aqueous electrolytes. The steric‐hindrance effect of TES− effectively shields I+ from nucleophilic attacks by hydroxyl groups, facilitating the reversible I−/I0/I+ conversion with four‐electron transfer.

Band-by-band spectral radiative kernels based on the ERA5 reanalysis

open access: yesScientific Data
Radiative kernel is a widely adopted method for diagnosing radiation variability and climate feedback. However, most of the existing radiative kernels are broadband flux kernels and lack the spectral information.

Moving hotspots [PDF]

open access: yes, 2001
The assumption that stationary hotspots underlie the Earth’s lithospheric plates has been most important in the development of the theory of plate tectonics. According to the fixed hotspot hypothesis seamount trails are formed by volcanism penetrating the

Origin of the Aves Ridge and Dutch–Venezuelan Antilles : interaction of the Cretaceous ‘Great Arc' and Caribbean–Colombian Oceanic Plateau? [PDF]

open access: yes, 2011
In this paper we reassess the geochronology and geochemistry of three dredge hauls from the SE corner of the Aves Ridge (Caribbean Sea) originally sampled in 1968 by Duke University's R. V. Eastward. Two hauls consist of light rare earth element-enriched

Tunable‐Threshold UV Dosimetry With Programmable Luminescent Tags via Oxygen‐Mediated Room‐Temperature Phosphorescence

open access: yesAdvanced Materials Technologies, EarlyView.
A fully organic UV threshold dosimeter is developed by exploiting the oxygen‐sensitive room‐temperature phosphorescence of a purely organic emitter in a polymer matrix. Upon reaching a specific cumulative UV dose, photochemical oxygen depletion triggers a sharp, high‐contrast emission.

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 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.

Bayesian‐Optimized Dual‐Mode Luminescence‐Based Optical Thermometry Enabled by Negative Thermal Expansion in Lu2(MoO4)3:Yb–Er–Tm Phosphor

open access: yesAdvanced Optical Materials, EarlyView.
A Bayesian optimization framework identifies the ideal composition for Lu2(MoO4)3:Yb–Er–Tm phosphors with minimal experimental trials. By leveraging the host's negative thermal expansion, the material achieves remarkable thermal quenching compensation.

An Oceanic Plateau Induced Subduction Zone Jump From Proto‐ to Paleo‐Tethys in East Kunlun, Northern Tibetan Plateau

open access: yesGeochemistry, Geophysics, Geosystems
The relationship between the Proto‐Tethys and Paleo‐Tethys is still debated. Some researchers believe that the Paleo‐Tethys opened after the Proto‐Tethys closed, while others argue that they are the same ocean with two stages of subduction.

Variety and origin of magmas on Shatsky Rise, northwest Pacific Ocean

open access: yesGeochemistry, Geophysics, Geosystems, 2012
Shatsky Rise consists of thick (∼30 km maximum) basaltic crust with various geochemical compositions. Geochemistry data indicate that four magma types exist on the plateau; namely normal, low‐Ti, high‐Nb, and U1349 types.

Oceanic mafic magmatism in the Siletz terrane, NW North America: Fragments of an Eocene oceanic plateau? [PDF]

open access: yes, 2017
The Siletz terrane, a predominantly mafic accreted oceanic terrane, is located in the Cascadia Forearc region of Oregon, Washington and Vancouver Island.
