3D‐Printed Crosslinked Nanocellulose‐MXene Hydrogels and Aerogels with High Strength and Conductivity

Small, EarlyView.
This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

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 ...

Characterization of the Pore Environments in Covalent Organic Frameworks by Dynamic Spin Probe Exchange

Small, EarlyView.
Covalent organic frameworks (COFs) with alkyl or triethylene glycol pore linings are probed with water‐dissolved nitroxide radicals using CW EPR spectroscopy. Adsorption affinity, local polarity, and radical concentration inside the pores are quantified, revealing hydrogen bonding, dipolar, and π‐π interactions that govern guest binding, which ...

Rapid Flow Synthesis of Zr‐MOF Nanoparticles in Supercritical CO2 for Toxic Chemical Removal

Small Methods, EarlyView.
Supercritical CO2 continuous‐flow synthesis produces highly crystalline Zr‐MOFs with residence times as short as 75 s. The resulting UiO‐66 and UiO‐66‐NH2 exhibit high porosity and effective adsorption and degradation of toxic chemicals. ABSTRACT Zirconium‐based metal‐organic frameworks (Zr‐MOFs) are promising materials for the adsorption and ...
