Revealing Structure–Property Coupling During Thermal Conversion of Metal–Organic Frameworks

open access: yesSmall, EarlyView.
Multifrequency atomic force microscopy (AFM) combined with hybrid density functional theory (DFT) and complementary spectroscopic techniques uncovers transient nanoscale states during Cu‐BTC MOF conversion. Intermediate Cu2O/CuO‐carbon nanocomposites maximize mechanical robustness and functionality, while fully oxidized porous CuO enhances light ...

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

open access: yesSmall, 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 ...

Scalable Room‐Temperature Terahertz Graphene Cameras

open access: yesSmall Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Rational Design of LiNi1‐xFexO2 Electrodes for Enhanced Oxygen Evolution Reaction Under Power‐Fluctuating Operations in Alkaline Water Electrolysis

open access: yesSmall Methods, EarlyView.
We develop Fe‐incorporated LiNiO2 for the OER in alkaline media, where Fe enhances Ni3+ oxidation state and optimizes eg orbital filling, significantly improving activity under power fluctuations. ABSTRACT The electrochemical performance of alkaline water electrolyzers is hindered by power fluctuations when integrated with renewable energy sources in ...

Impact of Plasma Ashing on Mixed Monolayer Doping of Silicon

open access: yesSmall Methods, EarlyView.
Mixed monolayer doping provides a controllable way to introduce phosphorus dopants into silicon. A gentle oxygen‐plasma treatment removes unwanted carbon while maintaining phosphorus on the surface. Following thermal diffusion, the treated silicon shows enhanced near‐surface n‐type behavior, demonstrating how carbon removal can tune molecular doping ...
