Ultrasonic rock sampling using longitudinal–torsional vibrations

open access: yesUltrasonics, 2010
In the last years several European and US space projects have been focused on the development of surface rovers for planetary missions, such as ExoMars and Mars Exploration Rovers. The main function of these vehicles consists of moving across planet surfaces, and drilling and retrieving samples for in situ analysis.

Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing

open access: yesAdvanced Functional Materials, EarlyView.
In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...
