Microstructures of Fe-16wt%S-2wt%Si in Partial and Complete Melt Regions at High Pressures: Implications for Dynamics in Small Planetary Cores

open access: yesCrystals
Regions of partial melt of Fe-S-Si alloys at high pressures may arise during planetary formation or at the boundary of the inner and outer cores of small terrestrial planetary bodies.

Anatexis and enrichment mechanism of the Fe-Ti oxide minerals in the quartzofeldspathic gneisses from the Larsemann Hills, East Antarctica

open access: yesDizhi lixue xuebao, 2021
Fe-Ti oxide minerals can be locally aggregated or enriched in the quartzofeldspathic gneisses from the Larsemann Hills, East Antarctica. The enrichment is related to anatexis and subsequent high-grade metamorphism, not inherited from the protolith.

Insights on Upper Mantle Melting, Rheology, and Anelastic Behavior From Seismic Shear Wave Tomography

open access: yesGeochemistry, Geophysics, Geosystems, 2018
In seismic tomography we map the wave speed structure inside the Earth, but we ultimately seek to interpret those images in terms of physical parameters.

Impact-induced changes in source depth and volume of magmatism on Mercury and their observational signatures

open access: yesNature Communications, 2017
Mantle partial melting produced the volcanic crust of Mercury. Here, the authors numerically model the formation of post-impact melt sheets and find that mantle convection was weak at around 3.7–3.8 Ga and that the melt sheets of Caloris and Rembrandt ...

Viscosity Measurements of FeO-Fe2O3-SiO2-Al2O3 Slag Melt Under Suppression of Magnetite Formation

open access: yesJournal of MMIJ, 2021
A stabilized zirconia oxygen probe was used to measure the oxygen partial pressure (OPP) at an electrode submerged in a copper slag melt at 1300 ℃. The OPP was controlled in the range of 10−10–10−5 atm owing to the presence or absence of a powdered ...

Recrystallization and Melting of Partially Melted Stark Rubber

open access: yesRubber Chemistry and Technology, 1967
Abstract Two specimens from a piece of stark rubber which had a melting temperature originally at 41° C were partially melted at 38° C and allowed to stand for 11 years, one at about 25° C, the other at 38° C. The first showed a continuous slow decrease in specific volume, while the second increased slowly in volume for 5 months and remained ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Seismic velocity structures and deep dynamic processes in the crust and mantle beneath the Tianshan Orogenic Belt

open access: yes地球与行星物理论评
As a typical region of intracontinental orogeny, the Tianshan Orogenic Belt has consistently attracted significant scientific interest from geologists, both in China and internationally.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

CO2‐Undersaturated Melt Inclusions From the South West Indian Ridge Record Surprisingly Uniform Redox Conditions

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The behavior of Fe3+ during mantle partial melting strongly influences the oxidation state of the resulting magmas, with implications for the evolution of the atmosphere's oxidation state.
