Electronic Structure Modulation via Composition‐Preserving Phase Transformations in Metal–Organic Assemblies on the Surface

open access: yesSmall, EarlyView.
We observed composition‐preserving stepwise transformation of metal–organic self‐assembly at room temperature and systematically investigated the consequent modification in electronic structure using scanning tunneling microscopy and spectroscopy (STM/STS), combined with density functional theory (DFT) calculations.

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

open access: yesSmall, EarlyView.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

open access: yesSmall, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Diamine Grafting of Pyrazole‐Based MOF‐303 for Diluted‐Source CO2 Capture

open access: yesSmall, EarlyView.
Vapor‐phase diffusion of ethylenediamine (EDA) into the pyrazole‐based MOF‐303 framework enables efficient amine grafting via pyrazole deprotonation and ion‐pair–stabilized hydrogen bonding with the pore walls. Spectroscopic analyses elucidate the interaction, while breakthrough experiments confirm the material's performance and cyclability.
