Using an economic method to prepare TiO2 from natural ilmenite for photodegradable dye removal

Results in Chemistry
In this work, nanoparticles of ilmenite powder (47 nm) were prepared via ball-milling of natural ilmenite ore to enhance the specific surface area of particles. The photocatalytic activity of magnetically separable ilmenite nanoparticles was investigated

Multistage Evolution and Inheritance in a Magma‐Poor Conjugate Margin: Insights From Serpentinized Peridotites of the Newfoundland Margin (ODP Hole 1277A)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The nature of mantle sections exhumed at magma‐poor rifted margins remains poorly constrained, largely because direct sampling of mantle in modern passive margins is exceptionally rare. The Iberia–Newfoundland system is unique in providing drilled mantle rocks on both conjugate margins, offering an unprecedented glimpse into mantle ...

The Wilson Cycle of the North Altyn Ocean: A Record of Subduction Initiation, Slab Rollback, and Final Closure

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The North Altyn ophiolitic belt was formed by the subduction–closure of the Altyn segment of the Proto–Tethys Ocean and recorded the accretion of Tarim to northern Gondwana, but the timing of initial subduction and detailed tectonic transition processes remain poorly constrained. This study reports the oldest Phanerozoic magmatic record of 537

Quantitative Evaluation of Shock Metamorphism in Clinopyroxene Using In Situ X‐Ray Diffraction Measurement of Lattice Strain

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Shock metamorphism is a ubiquitous process in our solar system. Shock pressure can be related to the lattice strain (ε) of individual minerals within a shocked sample. The lattice strain can be quantified within intact samples by in situ micro‐X‐ray diffraction (μXRD) using the Williamson‐Hall method. The Williamson‐Hall lattice strain (W‐H ε)
