Orientation controlling of Ni-based single-crystal superalloy by a novel method: grain selection assisted by un-melted reused seed

open access: yesJournal of Materials Research and Technology, 2019
A new grain selection method assisted by un-melted short seed was proposed to control the primary and secondary orientations of Ni-based single-crystal superalloy.

A numerical analysis of buoyancy-driven melting and freezing [PDF]

open access: yes, 2004
A numerical investigation of transient natural convective heat transfer with coupled phase change is presented. The numerical model attempts to capture the solid-fluid interface using a fixed-grid solution and is applied to two pure substance cases found

Biomimetic Cell Membrane‐Coated MOFs System for Targeted Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Biomimetic MOF‐based drug delivery nanoplatforms synthesized using liposomes or cell membranes as camouflage for multiple cancer therapeutics. ABSTRACT The integration of metal‐organic frameworks (MOFs) with cell membrane coatings has emerged as a revolutionary strategy to enhance the therapeutic efficacy of cancer nanomedicine.

Rapakivi K‐Feldspar Megacrysts in Monzogranitic Porphyry: Evidence for Magma Recharge and Mush Rejuvenation

open access: yesGeochemistry, Geophysics, Geosystems
The formation, storage, and evolution of granitic magmas are fundamental processes driving the growth of continental crust. While traditionally attributed to crystal fractionation in high‐melt fraction magma chambers, the model invoking low‐melt fraction

Magmatic to solid-state evolution of a shallow emplaced agpaitic tinguaite (the Suc de Sara dyke, Velay volcanic province, France): implications for peralkaline melt segregation and extraction in ascending magmas [PDF]

open access: yesEuropean Journal of Mineralogy
In the last decades the mush model has been generalized to the complete trans-crustal magmatic system in which differentiation would be driven by segregation and extraction of trapped melts from crystal-rich mushes. Melt extraction processes involved are

Magma Reservoir Formation and Evolution at a Slow-Spreading Center (Atlantis Bank, Southwest Indian Ridge)

open access: yesFrontiers in Earth Science, 2020
Several ODP-IODP expeditions drilled oceanic core complexes interpreted as exhumed portions of lower crust close to the ridge axis, and provide the community with invaluable sampling opportunity for further constraining magmatic processes involved in the

Cluster‐Mediated Solute Stabilization and Shear‐Bypass Synergistic Strengthening in High‐Alloyed Systems

open access: yesAdvanced Science, EarlyView.
This study demonstrates that in high‐alloy systems, nanoclusters with high solute tolerance can effectively suppress compositional segregation. This mitigation leads to a concurrent 18.7% increase in strength and 41.5% improvement in ductility, which is attributed to a shear‐bypass synergistic strengthening mechanism. The findings provide a new pathway

Melt extraction with crystal entrainment from basaltic crystal mush, causing a dacitic pumice eruption from the mafic-dominant Iwate volcano, northern Honshu

open access: yesEarth, Planets and Space
The structure and evolution of the magma plumbing system that produced the dacitic Yukiura Pumice (YP) at Iwate volcano, northern Honshu, are constrained by petrography and rhyolite–MELTS simulations. The basaltic Yukiura Scoria (YS) eruption immediately

Formation of fast-spreading lower oceanic crust as revealed by a new Mg–REE coupled geospeedometer [PDF]

open access: yes, 2018
A new geospeedometer is developed based on the differential closures of Mg and rare earth element (REE) bulk-diffusion between coexisting plagioclase and clinopyroxene.
