Hybrid Ketone‐Mediated Purification Enables Ligand Preservation for Efficient PbS Colloidal Quantum Dot Optoelectronics

open access: yesSmall Structures, Volume 7, Issue 10, October 2026.
A Hansen solubility parameter‐guided purification strategy is developed to minimize surface ligand loss during PbS colloidal quantum dot (CQD) purification. A hybrid ketone antisolvent positioned near the effective purification boundary enables sufficient precipitation while preserving surface‐bound ligands.

The Aurora Vent Field at the Transition From Magmatic Accretion to Tectonic Extension on Gakkel Ridge: Constraints From Microseismicity and Aeromagnetic Observations

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The Aurora hydrothermal vent field (AVF) is the first confirmed active vent system on the Arctic Ocean seafloor, located at the western end of the ultraslow spreading Gakkel Ridge. It marks a distinctive endmember among ridge‐axis hydrothermal systems, where volcanic construction and ultramafic influence co‐exist.

Quantifying Water Ice in Regolith Mixtures via Infrared (1.2–2.5 μm) Reflectance Model Parametrization

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Water ice deposits occur on inner solar system bodies in sunlit and shadowed terrains. We develop approaches to remotely determine the mixing mode with regolith (areal vs. intimate), ice grain size, and abundance that reveal processes of ice formation, emplacement, and evolution.

Flip‐Flop Detachments Require Moderate Strength Contrasts Between Fault Zone and Fault Blocks

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Large‐offset detachment faults frequently occur at slow‐ and ultraslow‐spreading mid‐ocean ridges, especially where magma supply is limited. Observations show that detachments at ultraslow ridges often alternate in polarity (“flip‐flop” regime), but the mechanical controls governing their formation remain poorly understood.

Rapid non‐destructive assessment of leaf water status with low‐cost transmittance meters

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 10, Page 2873-2880, October 2026.
Abstract Tools for more efficiently managing agricultural production and the use of limited water resources are required in the context of a growing global population, while the increasing threat posed by droughts and wildfires necessitates improved methods for risk assessment, forecasting and early warning. Quantifying leaf water content is central to

Optimized Stacking Ensemble Machine Learning for Nondestructive Toxicological Risk Assessment of Fish Meat Using Hyperspectral Imaging

open access: yesJournal of Food Safety, Volume 46, Issue 5, October 2026.
Hyperspectral imaging and an optimized stacking ensemble learning model are developed for rapid, nondestructive toxicological assessment of fish meat. This framework integrated multiple machine learning classifiers to accurately distinguish toxicologically contaminated fish from fresh samples using both reduced (25‐band) and full (224‐band) spectral ...

TROPOMI and TROPI: UV/VIS/NIR/SWIR instruments

open access: yes, 2006
TROPOMI (Tropospheric Ozone-Monitoring Instrument) is a five-channel UV-VIS-NIR-SWIR non-scanning nadir viewing imaging spectrometer that combines a wide swath (114°) with high spatial resolution (10 × 10 km 2).
