Bilayers of two-dimensional van der Waals materials that lack an inversion center can show a novel form of ferroelectricity, where certain stacking arrangements of the two layers lead to an interlayer polarization. Under an external out-of-plane electric field, a relative sliding between the two layers can occur, accompanied by an interlayer charge transfer and a ferroelectric switching. We show that the domain walls that mediate ferroelectric switching are a locus of strong attractive interactions between electrons.

Determining London dispersive surface energy, polar thermodynamic variables, and Lewis acid-base behavior of solid surfaces is crucial in many industrial applications such as adhesion, catalysis, chemical engineering, biomaterials, and technologic processes. Inverse gas chromatography at infinite dilution is a powerful technique that allows the determination of the surface thermodynamic parameters of the interaction between solid materials and organic solvents. In their most recent study, Cho et al.

Health warning labels have been found to increase awareness of the harmful effects of tobacco products. An eye tracking study was conducted to determine the optimal placement and type of a health warning label on tobacco waterpipes. Participants viewed images that contained one of (1) four waterpipes, (2) three different types of warning labels, (3) placed in three locations.
