Towards a Scalable, AI‐Augmented Purification Platform for Amphetamine‐Type Stimulants: From Nanopolymer Synthesis to Predictive Process Simulation

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 5, May 2026.
ABSTRACT The prevalent formation of by‐products in conventional methamphetamine (MA) synthesis critically impairs final product purity, presenting a significant challenge that necessitates elaborate and costly downstream purification strategies. To overcome these limitations, this study introduces molecularly imprinted polymer (MIP)‐based nanopolymers ...

Upper‐Ocean Variability of the Marine Carbonate System in the Northeast Pacific

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract In the Northeast Pacific, the marine carbonate system's variability across timescales is not well constrained. Here, we quantify observed seasonal and non‐seasonal variability in Dissolved Inorganic Carbon (DIC), partial pressure of carbon dioxide (pCO2 ${\text{pCO}}_{2}$) and aragonite saturation state Ωa $\left({{\Omega }}_{a}\right)$ and ...

Integrating GRACE and InSAR Data to Assess Land Surface Displacement From Managed Aquifer Recharge

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Satellite‐based monitoring of groundwater changes and their surface effects is crucial for understanding hydrological processes and managing water resources in an era of increasing water scarcity. The Gravity Recovery and Climate Experiment follow‐on (GRACE‐FO) mission provides global measurements of terrestrial water storage anomalies, while ...

Bayesian‐Belief Direct Policy Search for Adaptive Water Supply Planning With Endogenous Learning

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Climate change uncertainty challenges water supply planning, where long‐lived infrastructure must ensure reliable supply under evolving conditions. Adaptive planning addresses this by incrementally expanding infrastructure only as needed, reducing unnecessary investments.

Spatial Variability in Trace Organic Compound Reactivity During Urban River Infiltration Into an Alluvial Aquifer

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Uncertainty Calibration in Molecular Machine Learning: Comparing Evidential and Ensemble Approaches

open access: yesChemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Raw uncertainty estimates from deep evidential regression and deep ensembles are systematically miscalibrated. Post hoc calibration aligns predicted uncertainty with true errors, improving reliability and enabling efficient active learning and reducing computational cost while preserving predictive accuracy.
