Landforms Associated With the Aspect‐Controlled Exhumation of Crater‐Filling Alluvial Strata on Mars
Geophysical Research Letters, 2023 Fluvial channel belts, the deposits accumulated in rivers surrounded by floodplain deposits, are sensitive environmental recorders. Across Mars, wind has exposed ancient channel belts via the preferential erosion of floodplain strata, creating landforms ...

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Electron Energization by Ion Density Enhancement in the Martian Magnetotail—MAVEN Observations
The Astrophysical JournalIt has been long observed at Mars that electron fluxes are enhanced during the tail current sheet crossings, of which the cause is not well understood. We use a novel approach to reveal one of the electron energization mechanisms with observations from ...

Advanced Engineering Materials, EarlyView.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

The Planetary Science JournalMercury has a very tenuous atmosphere starting at the surface, which is referred to as a surface-bound exosphere, where there are no collisions between exospheric particles.

Eos, Transactions American Geophysical Union, 2002 Thirty years ago, most important planetary research could be found within a modest monthly journal, an annual conference proceedings, and a smattering of articles in AGU and other publications. Since then, planetary science has become an enormously successful enterprise; its literature is now published in several dedicated journals and forms a major ...

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses
Advanced Engineering Materials, EarlyView.Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

DIVISION III: PLANETARY SYSTEMS SCIENCE [PDF]
Proceedings of the International Astronomical Union, 2008 The meeting was opened by Ted Bowell, president, at 11 am. The 2006 Division III meetings were reviewed by Guy Consolmagno, secretary; as the minutes of those meetings have already been published, they were assumed to be approved.
