SuperCam Raman Activities at Jezero Crater, Mars: Observational Strategies, Data Processing, and Mineral Detections During the First 1000 Sols

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract The Mars 2020 Perseverance rover introduced Raman spectroscopy to in situ planetary exploration for the first time when it landed in Jezero crater on Mars in February 2021. The SuperCam instrument onboard Perseverance is a multi‐analytical tool capable of acquiring time‐resolved Raman data from Martian targets at standoff distances of a few ...

Fault Permeability and Strength Evolution Related to Fracturing and Healing Episodic Processes (Years to Millennia): the Role of Pressure Solution Évolution de la perméabilité et de la résistance des failles associée à des processus épisodiques de fracturation et colmatage (années - millénaires) : le rôle de la dissolution cristallisation sous contrainte

Oil & Gas Science and Technology, 2011
It is well known that fluids flow through faults and fractures but it is also demonstrated that fault zones act as impermeable barriers. Consequently, one must consider that faults are successively open and closed paths for fluids.

3D SR‐μXCT analysis for lithology detection: Application to Ryugu sample A0159

Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2623-2654, November 2025.
Abstract Extraterrestrial breccia samples are formed through impact‐related processes that combine the fragments of distinct lithologies. As such, they are valuable indicators of the complex formation and evolution history of planetesimals in our solar system.

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties

Advanced Functional Materials, Volume 35, Issue 42, October 15, 2025.
This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Fluid Flow in Low Permeable, Porous Media Écoulements fluides dans un milieu poreux peu perméable

Oil & Gas Science and Technology, 2006
Migration of hydrocarbons deals with the subsequent movement of petroleum after expulsion from the source rock through water saturated reservoirs or through permeability created by fractures and faults. Although the underlying principles that control the

Image registration algorithm for molecular tagging velocimetry applied to unsteady flow in Hele-Shaw cell [PDF]

, 2013
In order to develop velocimetry methods for confined geometries, we propose to combine image registration and volumetric reconstruction from a monocular video of the draining of a Hele-Shaw cell filled with water.

Synchrotron 4D X‐Ray Computed Tomography of a Porous Limestone: Influence of Porosity on Deformation Mechanisms at Multiple Scales

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract This study investigates the relationship between deformation mechanisms and heterogeneity of porosity of a porous carbonate rock across several scales. The Saint Maximin limestone (SML), characterized by centimeter‐scale alternations of dense and porous zones, serves as a model rock to examine the evolution of deformation modes.
