Anisotropy of π–π Stacking as Basis for Superlubricity
When two surfaces move against each other, often high adhesive strength with low friction is desired. Then, the interfacial interaction requires a strong directional anisotropy, as provided by π–π stacking.

Arylene Ethynylene Macrocycles with Intramolecular π−π Stacking
, 2016 Arylene ethynylene macrocycles containing 9,10-anthrylene or 1,4-naphthylene units were synthesized. In chloroform, significant resonance upfield shifting was observed with β-protons of anthrylene and naphthylene in NMR spectra.

Reversible Loss of Bernal Stacking during the Deformation of Few-Layer Graphene in Nanocomposites [PDF]
, 2013 The deformation of nanocomposites containing graphene flakes with different numbers of layers has been investigated with the use of Raman spectroscopy. It has been found that there is a shift of the 2D band to lower wavenumber and that the rate of band ...

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes
Advanced Functional Materials, EarlyView.We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces
