Advanced Engineering Materials, EarlyView.Micro‐Raman spectroscopy is applied to characterize corrosion products in a recycled‐based MgO–316L steel composite anode after molten salt electrolysis. A depth‐dependent Fe–O/Fe–Al–O layer sequence of magnetite, hercynite, and an Al‐doped magnetite transition zone is identified.

Advanced Engineering Materials, EarlyView.This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Can we constrain interior structure of rocky exoplanets from mass and radius measurements? [PDF]
, 2015 We present an inversion method based on Bayesian analysis to constrain the interior structure of terrestrial exoplanets, in the form of chemical composition of the mantle and core size.

Eos, Transactions American Geophysical Union, 1985 The effective definition of a planet is a body too small to sustain nuclear reactions in its interior, but large enough that its thermal decay time is more than five billion years, the age of the solar system. By this definition, there are fifteen planets in the solar system: all the conventional planets but Pluto plus the seven large satellites.

Ohmic Dissipation in the Atmospheres of Hot Jupiters
, 2010 Hot Jupiter atmospheres exhibit fast, weakly-ionized winds. The interaction of these winds with the planetary magnetic field generates drag on the winds and leads to ohmic dissipation of the induced electric currents.

Models of Saturn's Interior Constructed with Accelerated Concentric Maclaurin Spheroid Method [PDF]
, 2019 The Cassini spacecraft's Grand Finale orbits provided a unique opportunity to probe Saturn's gravity field and interior structure. Doppler measurements yielded unexpectedly large values for the gravity harmonics J_6, J_8, and J_10 that cannot be matched ...

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process
Advanced Engineering Materials, EarlyView.This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...

Salt Distribution from Freezing Intrusions in Ice Shells on Ocean Worlds: Application to Europa
The Planetary Science Journal, 2023 Several icy moons and dwarf planets appear to have hosted subsurface liquid water. Liquid water intruding upwards into the icy outer shells of these worlds freezes, forming ice and (from ocean solutes) non-ice solids.

Architecture of Kepler's Multi-transiting Systems: II. New investigations with twice as many candidates [PDF]
, 2014 We report on the orbital architectures of Kepler systems having multiple planet candidates identified in the analysis of data from the first six quarters of Kepler data and reported by Batalha et al. (2013).

Eos, Transactions American Geophysical Union, 1971 Most publications on planetary interiors in the last 4 years have dealt with the moon, and the most popular topic has been the interpretation of lunar mascons (the nature and discovery of mascons are covered in the review ‘Selenodesy and Planetary Geodesy’ by W. M. Kaula).
