Chirality-driven ferroelectricity in LiCuVO4

Ferroelectricity driven magnetism at domain walls in LaAlO3/PbTiO3 superlattices

Charge dipole moment and spin moment rarely coexist in single-phase bulk materials except in some multiferroics. Despite the progress in the past decade, for most multiferroics their magnetoelectric performance remains poor due to the intrinsic exclusion between charge dipole and spin moment. As an alternative approach, the oxide heterostructures may evade the intrinsic limits in bulk materials...

Ferroelectricity driven by twisting of silicate tetrahedral chains.

Chirality-dependent buckling-driven wrinkles in graphene monolayer

It is of great significance to understand the underlying mechanism of buckling-driven wrinkles in graphene monolayer due to its applications in nanoelectromechanical systems (NEMS). In previous macroscopic studies based on continuum theory, the chirality-dependent buckling in graphene monolayer is considered as neglectable. However, we found that the growth of buckling-driven wrinkles in graphe...

Light-driven molecular switches with tetrahedral and axial chirality.

Two light-driven molecular switches with tetrahedral and axial chirality were synthesized, which can induce a helical superstructure in an achiral liquid crystal host and dynamically phototune it to achieve reversible reflection color.

Chirality-driven folding of short β-lactam pseudopeptides.

Novel enantiopure pseudopeptide models containing a central -(β-lactam)-(Aa)- scaffold characterized by the combined presence of an α-alkyl-α-amino-β-lactam (i+1) residue and a α-substituted (i + 2) amino acid have been readily synthesized from α-alkyl serines. The conformational analysis of such β-lactam pseudopeptides conducted in CDCl(3) and DMSO-d(6) solutions using 1D- and 2D-NMR technique...
