One‐Pot Base‐Free Suzuki‐Miyaura [11C]Methylation: Kinetic and Mechanistic Insights

open access: yesChemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.
A base‐free Suzuki–Miyaura [11C]methylation is achieved in a one‐pot process with [11C]CH3I on moderate yields. Electronic effects enable transmetallation without boronate activation, while kinetics and DFT show oxidative addition (heterolytic) as the rate‐limiting step.

Hierarchically MOF‐Based Porous Monolith Composites for Atmospheric Water Harvesting

open access: yesAdvanced Materials, Volume 38, Issue 1, 2 January 2026.
This review explores the design of hierarchical porous materials for atmospheric water harvesting, focusing on metal‐organic frameworks (MOFs) and porous monoliths. Emphasis is placed on integrating MOF nanoscale porosity with the microscale channels of monolithic scaffolds to enhance sorption‐desorption performance.
