Key New Evidence for the Hainan Mantle Plume Head: Ongoing Formation of a Large Igneous Province?

Geochemistry, Geophysics, Geosystems
The process‐based surface magmatic expression of mantle plumes is typically a large igneous province (LIP) induced by the mantle plume head, followed by subsequent age‐progressive volcanic tracks resulting from plate drifting above the plume tail ...

Phase analysis of complex non-metallic inclusions in Al-deoxidized 42CrMo4 steel after contact with MgO–C refractories

Open Ceramics, 2023
This study extensively investigated characteristic non-metallic inclusions in oxidized and deoxidized 42CrMo4 steel after contact to MgO–C refractories, proposing possible formation and modification mechanisms of non-metallic inclusions.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Evaluating and optimizing Raman analytical protocols for CO2 fluids

Volcanica
Raman spectroscopy is widely used to quantify CO2 density in geological fluids, yet acquisition parameters, spectral processing methodologies and densimeter calibrations vary between laboratories.

Shape evolution due to melt inclusion faceting.

, 2012
(a) Shape change of a melt inclusion inside a host crystal as a function of time due to faceting; initial inclusion is spherical, but with time gets transformed into a polyhedron with rounded edges; with sufficient time, inclusion may become a perfect ...

Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]

, 1985
The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.

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.

Separation of inclusion particles from aluminum melt by super gravity

工程科学学报, 2018
The increasing demand for high-quality aluminum alloys in the automobile industry and other manufacturing fields has motivated manufacturers to produce cleaner aluminum alloys. However, conventional methods can barely meet the cleanliness requirements of

Oldest Immiscible Silica‐rich Melt on the Moon Recorded in a ~4.38 Ga Zircon

Geophysical Research Letters, 2020
The temporal duration of lunar‐evolved magmatism is still poorly constrained. In lunar meteorite Northwest Africa (NWA) 10049, a melt inclusion‐bearing zircon fragment provides a new tool to understand the composition and age of the melts from which ...

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.
