A Versatile Heterometallic Microporous MOF for Photocatalytic Hydrogen Generation

Small, EarlyView.
This work describes a green and scalable approach to robust and flexible heterometallic MOFs, MIP‐215's, with tunable photoactivity for efficient, noble‐metal‐free solar hydrogen production. ABSTRACT Photocatalytic particulate systems offer a cost‐effective solar hydrogen production but are generally limited by narrow visiblelight absorption and poor ...

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

Small, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.

Engineering metal‐organic framework‐based smart porous nanoplatforms for targeted therapy and theranostic applications

Smart Molecules, EarlyView.
MOFs offer high porosity and tunability for biomedical applications, especially in cancer therapy via ROS generation and targeted delivery. Though toxicity, stability, and scalability remain key clinical challenges. Drug loading in MOFs exceeds 60%–70% with controlled release behavior.

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
