Voltage‐Induced Hysteretic Resistance in Nematic Order of SmFeAsO

open access: yesAggregate, EarlyView.
Electronic origin of nematicity revealed! This study uncovers a unique voltage‐driven hysteresis effect in the SmFeAsO's nematic phase through the advanced point‐contact spectroscopy. A bias voltage drives the point contact through antiferromagnetic and structural transitions via the ballistic Joule heating effect, revealing a distinctive hysteretic ...

Covalent Bond Regulation in Nanographene: En Route to Precise Aggregation State Modification

open access: yesAggregate, EarlyView.
Regulation of nanographene from covalent bond to control the aggregation state of nanographene precisely was achieved by protonic acid or Lewis acid. The fused azulene unit(s) at the margin of molecules played an important role for the unique chemical activity and physical features. Furthermore, quencher and reaction temperature would lead to selective

Automatic Determination of Quasicrystalline Patterns from Microscopy Images

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

Synthesis and Physical Properties of Salphen‐Conjugated TTF‐Metal Complex [CuII(TTF‐Salphen)]2PF6

open access: yesAsian Journal of Organic Chemistry, EarlyView.
A paramagnetic metal complex, [Cu(TTF‐Salphen)], in which a tetrathiafulvalene (TTF) moiety is conjugated with a Salphen coordination site, was synthesized as a potential candidate for a new π‐d system. Its radical salt, [Cu(TTF‐Salphen)]2PF6, exhibits high electrical conductivity with semiconducting behavior, attributed to its columnar stacking ...
