A Thirty‐Year Gap: Reviving All‐Nitride Glasses as Processable, High‐Performance Materials

open access: yesAdvanced Science, EarlyView.
Oxygen‐free all‐nitride glasses are revisited in light of new avenues of synthesis, raw material availability, and applications. A semi‐empirical analysis predicts mechanical performance achieving the level of engineering ceramics while maintaining visual transparency, and significant potential regarding optical properties into the infrared spectral ...

Progress in mantle anisotropy research based on XKS phases

open access: yes地球与行星物理论评
XKS shear-wave splitting has been widely applied to investigations of anisotropy in both the upper mantle and the lowermost mantle D" layer, and represents a key tool for probing mantle deformation and dynamics.

Seismotomography of the mantle under the East European platform: mantle velocity boundaries

open access: yesГеофизический журнал, 2012
Mantle velocity boundaries of EEP have been specified. For the upper mantle and its tranzi-tion zone dynamics of propagation of mantle velocity limits with depth has been presented.

Inference of the Timescale‐Dependent Apparent Viscosity Structure in the Upper Mantle Beneath Greenland

open access: yesAGU Advances, 2023
Contemporary crustal uplift and relative sea level (RSL) change in Greenland is caused by the response of the solid Earth to ongoing and historical ice mass change.

Impact of upper mantle convection on lithosphere hyperextension and subsequent horizontally forced subduction initiation [PDF]

open access: yesSolid Earth, 2020
Many plate tectonic processes, such as subduction initiation, are embedded in long-term (>100 Myr) geodynamic cycles often involving subsequent phases of extension, cooling without plate deformation and convergence. However, the impact of upper mantle

The upper mantle beneath the Gulf of California from surface wave dispersion. Geologica Ultraiectina (299) [PDF]

open access: yes, 2009
This thesis is a study on upper mantle shear velocity structure beneath the Gulf of California. Surface wave interstation dispersion data were measured in the Gulf of California area and vicinity to obtain a 3-D shear velocity structure of the upper ...

Mitochondrial Localization of Cx26 Promotes Colorectal Cancer Malignancy and Exposes a Fatal Vulnerability to Drug Targeting

open access: yesAdvanced Science, EarlyView.
Mitochondrial localization of Cx26 emerges as a double‐edged sword in colorectal cancer. PIMT‐mediated methylation of Cx26 promotes its mitochondrial localization and stability. Mitochondrial Cx26 then facilitates ER‐mitochondria communication and Ca2+ signaling, thereby promoting metastatic progression. Bortezomib exploits this malignant adaptation by

ScS shear-wave splitting in the lowermost mantle: Practical challenges and new global measurements

open access: yesSeismica
Many regions of the Earth's mantle are seismically anisotropic, including portions of the lowermost mantle, which may indicate deformation due to convective flow.

Noble gases confirm plume-related mantle degassing beneath Southern Africa

open access: yesNature Communications, 2019
Southern Africa is characterised by unusually elevated topography and abnormal heat flow. This can be explained by thermal perturbation of the mantle, but the origin of this is unclear.

Mantle pseudo-isochrons revisited [PDF]

open access: yes
The 2.0 Ga pseudo-isochron age inferred from the mid-ocean ridge basalt 207Pb/204Pb against 206Pb/204Pb diagram is reexamined on the basis of a statistical box model of mantle processes.
