Some dynamical consequences of partial melting in Earth's deep mantle
, 2007 International audienceWe use regional scale numerical models of mantle convection to investigate the simple hypothesis that seismically anomalous thin patches of Earth's lowermost mantle, termed “ultralow-velocity zones” or ULVZ, are derived from partial

Advanced Engineering Materials, EarlyView.A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Geochemistry, Geophysics, GeosystemsOcean island basalts (OIB) provide valuable constraints on mass exchange between the mantle and crust. When appropriate compositional data transformations are applied, multivariate analyses of OIB compositions can be used to infer mantle source ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys
Advanced Engineering Materials, EarlyView.This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

Modelling the controls on melt generation during continental extension and breakup
, 2008 Rifting is the process that leads to the formation of oceans. Rifting is the break up ofcontinents, leading to the formation of new oceanic floor between the two continentalplates.
