Stratigraphy of Carbonate‐Bearing Rocks at the Margin of Jezero Crater, Mars: Evidence for Shoreline Processes?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian carbonate‐bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine‐ and carbonate‐bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim ...

Using the Finite Element Method to Determine the Temperature Distributions in Hot-wire Cutting. [PDF]

open access: yes, 2011
Hot-wire cutting is a common material removal process used to shape and sculpt plastic foam materials, such as expanded polystyrene (EPS). Due to the low cost and sculpt-ability of plastic foams they are popular materials for large sized (> 1 m³ ...

Piezoelectric Nanofiber Mats With Enhanced Elastic Recovery for Smart Fabrics

open access: yesAdvances in Polymer Technology, Volume 2026, Issue 1, 2026.
Piezoelectric polymer nanofibers are promising for wearable electronics due to their mechanical compliance and electromechanical responsiveness. Poly(vinylidene fluoride)‐trifluoroethylene (PVDF‐TrFE) is widely used for its ferroelectric β‐phase and favorable piezoelectric properties, yet its limited elasticity hinders applications in soft ...

Manufacturing a thin wire electrostatic trap (TWIST) for ultracold polar molecules

open access: yes, 2007
We present a detailed description on how to build a Thin WIre electroStatic Trap (TWIST) for ultracold polar molecules. It is the first design of an electrostatic trap that can be superimposed directly onto a magneto optical trap (MOT).
