Spiropyran‐Crosslinked PDMS Optical Waveguides for Pressure Sensing and Visual Cue of Localized Pressure Threshold

Polymers for Advanced Technologies, Volume 37, Issue 10, October 2026.
ABSTRACT Compliant optical waveguides are promising candidates for stress/strain sensing in soft robotics and personalized healthcare. While poly(dimethylsiloxane) (PDMS) offers a robust platform, enhancing sensitivity and integrating localized visual indicators for pressure threshold detection remains an active area of research.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

Small, Volume 22, Issue 56, 8 October 2026.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

Europa's Neutral Sodium Exosphere Is Quasi‐Stable Over Decades

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Europa's sodium cloud is thought to be modified by its orbital longitude and by its plasma environment, which modulates with Jovian magnetic geometry. To explore and quantify sodium cloud variability, seven sets of Keck I/HIRES measurements are compared providing comprehensive coverage of orbital and magnetic geometry.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Gas Measurements Reveal Fractional Degassing and Water Interaction During a Flank Eruption of Pacaya Volcano (Guatemala)

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.

Numerical Simulations of 3D Scattering Structures Reveal Systematic Underestimation of Marsquake Magnitudes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...
