The domination of Saturn's low latitude ionosphere by ring `rain' [PDF]
Saturn's ionosphere is produced when the otherwise neutral atmosphere is exposed to a flow of energetic charged particles or solar radiation. At low latitudes the latter should result in a weak planet-wide glow in infrared (IR), corresponding to the ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Ringed versus Ringless Worlds: How Poynting–Robertson Drag Shapes Rings across the Solar System
Planetary rings are not only ubiquitous around the giant planets in the outer solar system, but have also been discovered around several small distant bodies. In contrast, no rings have been observed around any inner solar system objects.

This article demonstrates the successful qualification of a copper–tungsten composite for laser powder bed fusion. The resulting components exhibited high density, high thermal conductivity, and reduced thermal expansion. Heat sinks with complex geometries were successfully manufactured, clearly showcasing the material's potential for additive ...

The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

This work presents a simulation‐based framework based on representative volume elements (RVEs) that explicitly incorporates process‐induced second‐order residual stresses into the fatigue strength assessment of ductile cast iron (DCI). For the first time, this approach enables a direct evaluation of the influence of second‐order residual stress fields ...

A Dust Halo from Saturn’s Main Rings Extending Several Saturnian Radii above the Ring Plane
During the Grand Finale orbits, the Cassini spacecraft orbited Saturn with high inclinations and perikrones near the ring plane crossings. The Cosmic Dust Analyzer sampled ice and mineral dust particles during these orbits.
