Sound speed and diffusion in 2D Yukawa liquids: Effect of dipole–dipole interaction

Abstract

The two‐dimensional (2D) Yukawa liquid with an additional screened dipole–dipole interaction is considered in connection with the 2D system of charged dust particles in complex plasmas. Particularly, the sound speed and diffusion in the case the Yukawa interaction potential dominant over the screened dipole–dipole interaction are analysed. Increase in the value of the sound speed and suppression of the super‐diffusion due to the additional dipole–dipole interaction are reported. This effect is explained by the stronger inter‐particle correlations induced by the additional dipole–dipole interaction.

Physical and Rheological Properties of Maleic Anhydride-Incorporated PVDF: Does MAH Act as a Physical Crosslinking Point for PVDF Molecular Chains?

“…Besides, the intermolecular interactions between the two components in the blend play an important role in their miscibility. The four most common interactions include the acid–base type, hydrogen bonding, dipole–dipole, and charge-transfer interactions. In particular, hydrogen bonding often acts as a miscibility enhancer, which has been proved in several studies. , A vast majority of the studies have emphasized that PVDF/poly­(methyl methacrylate) (PMMA) are completely miscible because of the hydrogen-bonding interactions between the carbonyl group of PMMA and the acidic hydrogen of PVDF. , Additionally, various nanofillers have been used to modify the PVDF matrix, leading to the improvement of the mechanical and ferroelectric properties of PVDF. − Tiwari reported the preparation of polar PVDF by amine-modified porous silica nanofillers.…”
