Local Ionic Displacements and Polarization at the Paraelectric‐Ferroelectric Heterointerface: Effect of Octahedral Distortion

The cation–cation displacement gradually increases across the paraelectric-ferroelectric heterointerface and scales with the tetragonality of the perovskite unit cell but not with the polarization. However, the oxygen octahedral distortion, accompanied by octahedral rotation, leads to the comparable cation–oxygen displacement in the substrate with that...

Enhanced Rashba Splitting of Au(111) Surface States with Hydrogen‐Bonded Melamine‐Based Organic Framework

Melamine forms domains with different pseudo-chirality on Au(111) via double hydrogen bonds. These domains are formed at the same time that the molecule is adsorbed via cooperative hydrogen bonds. This hydrogen-bonded organic framework of melamine doubles the size of the Rashba splitting of the Au(111) Shockley surface states. Abstract Molecular...

Constructing “Soft‐Stiff” Structure on the Surface of Carbon Fiber to Enhance the Interfacial Properties of Its Epoxy Composites

The interfacial interaction between fiber and resin is enhanced by constructing a “soft-stiff” structure on carbon fiber (CF) surface. The interlaminar shear strength and flexural strength of the modified composites are 66.2 and 914.1 MPa, respectively, which are 47.4% and 48.2% higher than pristine CF/epoxy composites. This work provides a potential...
