How electrons in moiré graphene populate valleys and carry spin has consequences for understanding its superconductivity. Now, evidence suggests that twisted trilayer graphene has a spin-polarized, valley-unpolarized configuration.

Controlling the crystallographic registry of layered materials through interlayer twist angles has introduced a distinctive degree of freedom for tuning their electronic behaviour. Now, the interfacial electrochemical kinetics of solution-phase redox complexes at twisted bilayer graphene electrodes have been modulated by the angle-dependent tuning of moiré-derived flat bands.

Sonication of layered metallacycle crystals gives free-standing nanosheets held together by weak non-covalent interactions, with chiral surfaces that show improved binding and enantiodiscrimination compared with individual metallacycle molecules.
