Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

Transient, Localized Flux Transport Revealed by Electron Microsignatures Downstream of Saturnian Moons

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In Saturn's magnetosphere, the inward transport of magnetic flux is largely carried by localized injection flux tubes filled with warm, tenuous plasma, although their inflow speeds and spatio‐temporal properties remain poorly constrained. Here, we propose that these flux tubes can modify electron microsignatures, the small‐scale, absorption ...

From Rigid to Elastic: Tailoring the Properties of Linear Poly(IBOA‐co‐2EHA) Copolymers Synthesized by UV Polymerization

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 7, February 15, 2026.
The combination of a rigid monomer (IBOA) and a flexible monomer (2‐EHA) via free‐radical copolymerization yields amorphous poly(IBOA‐co‐2‐EHA) with a wide range of tunable mechanical properties. The image depicts how increasing the IBOA content shifts the material's behavior from that of an elastic elastomer (PEHA) to a rigid, brittle plastic (PIBOA),

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Biosynthesis of Silver Nanoparticles Using Black Pepper (Piper nigrum) Seed Extract and Evaluation of Their Cytotoxicity

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study reports the green biosynthesis of piperine‐functionalized silver nanoparticles from Piper nigrum seed extract, followed by comprehensive physicochemical characterization and in vitro cytotoxic evaluation. The results confirm successful nanocomposite formation and demonstrate a marked enhancement of cytotoxic activity against gastric cancer ...
