Origin of alkali-rich volcanic and alkali-poor intrusive carbonatites from a common parental magma

Scientific Reports, 2021
The discrepancy between Na-rich compositions of modern carbonatitic lavas (Oldoinyo Lengai volcano) and alkali-poor ancient carbonatites remains a topical problem in petrology.

Volatile diffusion in silicate melts and its effects on melt inclusions

Annals of Geophysics, 2005
A compendium of diffusion measurements and their Arrhenius equations for water, carbon dioxide, sulfur, fluorine, and chlorine in silicate melts similar in composition to natural igneous rocks is presented. Water diffusion in silicic melts is well studied and understood, however little data exists for melts of intermediate to basic compositions.

Polymineralic inclusions in mantle chromitites from the Oman ophiolite indicate a highly magnesian parental melt

, 2018
Polymineralic inclusions interpreted as melt inclusions in chromite from the dunitic Moho Transition Zone in the Maqsad area of the Oman ophiolite have been analysed and compositions integrated using a rastering technique on the scanning electron ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Ca/Al of plagioclase-hosted melt inclusions as an indicator for post-entrapment processes at mid-ocean ridges?

Geologica Acta, 2016
The composition of melt inclusions in basalts erupted at mid-ocean ridges may be modified by post-entrapment processes, so the present composition of melt inclusions may not represent their original composition at the time of entrapment. By combining the

Revealing interfacial properties and agglomeration characteristic of rare earth aluminate inclusion in molten steel

Journal of Materials Research and Technology
The formation of large, harmful rare earth (RE) inclusions in RE-containing steels is closely related to their agglomeration behavior, which is strongly influenced by the interfacial properties between inclusions and molten steel.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

In-situ observation of inclusion agglomeration characteristics in high-manganese and high-aluminum steels with different Mn and Al contents

Materials & Design
Elucidating the agglomeration behavior of inclusions is critical for optimizing the quality of high-manganese and high-aluminum steels. This study predicted the precipitation behavior of inclusions using thermodynamic modeling.

The inclusion removal behavior during electron beam smelting of DD98M alloy

Journal of Materials Research and Technology, 2022
The DD98M alloy was prepared by electron beam smelting, and the effect of electron beam smelting parameters on the inclusion removal behavior was studied. The inclusion removal thermodynamics and kinetic mechanisms were analyzed.
