High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

Geological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Reactive selenium induced near‐surface reconstruction to stabilize high‐voltage, cobalt‐free cathodes for high‐rate, long‐cycling lithium batteries

InfoMat, EarlyView.
To address the challenges of structural degradation and side reactions with the electrolyte during cycling for spinel LNMO cathode, we propose a reactive Se‐induced near‐surface reconstruction strategy, integrating SeOx coating and Se doping into the near‐surface of LNMO via a one‐step selenization process.

A strategy for modulation of permittivity in manganese doping to induce lattice distortion

InfoMat, EarlyView.
Manganese atoms are doped into the NiCo2O4 spinel structure by atomic substitution, which increases structural stability through the formation of manganese–oxygen bonds. The resulting lattice distortion leads to a significant increase in dielectric permittivity. Achieving an electromagnetic wave reflection loss of −63.40 dB thus provides useful insight
