3D‐Printed Geopolymer as a Basic Heterogeneous Catalyst for the Synthesis of α‐Cyanoacrylates Through the Knoevenagel Condensation

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.

Observation‐Informed Machine Learning Convective Scheme: A New Training Strategy

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Machine learning (ML)‐based schemes face challenges in online stability and biases because of the accumulated errors during long‐term integrations. Here, we propose a new ML training strategy for the convection process that provides online corrections to tendencies in a more systematic way with significant improvements in stability and bias ...

A Dynamical Model of the Tropical Pacific Zonal SST Gradient Change Under Global Warming

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract How the tropical Pacific mean‐state sea surface temperature (SST) responds to global warming is an ongoing heated debate, as climate models are flawed and their projections are opposite to the observed zonal gradient strengthening. Here, we build a dynamical tropical Pacific air–sea coupled model that incorporates three key mechanisms of the ...

Influence of Variations in Gravity Wave Properties on Cirrus Ice Number Concentrations Produced by Homogeneous Freezing in the Tropical Tropopause Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract In this study, we examine the impact of variations in gravity wave properties on the ice crystal number concentrations in the tropical tropopause layer (TTL). Analysis of quasi‐Lagrangian superpressure balloon measurements from the Stratéole‐2 campaign shows that high‐frequency waves dominate the occurrence of relatively large vertical wind ...

Deforestation Impacts on Clouds and Precipitation Over Borneo Vary Across the Diurnal Cycle

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The impact of tropical deforestation on clouds and precipitation remains uncertain due to complex interactions between land and atmospheric processes on convective and mesoscales. Here, we examine convective‐scale processes controlling the short‐term atmospheric response to deforestation over Borneo using multi‐day large eddy simulations ...
