Special Issue Information

Dear Colleagues,

Intermolecular interactions, including van der Waals forces, hydrogen bonding, and electrostatic attractions, play an essential role in determining the properties and behaviors of various supramolecules and molecular materials. As molecular systems grow in complexity and size, the task of accurately predicting these interactions becomes increasingly challenging. Quantum mechanical methods have been instrumental in modeling intermolecular interactions, but they are limited to small and medium-sized systems due to their steep computational scaling. To overcome the challenge, researchers are increasingly turning to advanced computational techniques, such as low-scaling electron correlation methods and machine learning techniques, to enhance the accuracy and efficiency of computational predictions. Understanding and predicting intermolecular interactions in large molecular systems is essential for the development of novel materials, drugs, and biological systems. By leveraging cutting-edge computational methods and experimental techniques, researchers are paving the way for breakthroughs in these areas, with potential impacts across a wide range of scientific and technological fields.

This Special Issue is designed to gather scientific papers on intermolecular interaction predictions in large molecular systems. Progress in advanced computational methods, machine learning-based techniques, and experimental methods and other subjects can be discussed.

The properties of EVA copolymers with various vinyl acetate (VA) contents were compared, with EVA 206 (6 wt.% VA) and EVA 212 (12 wt.% VA) having the same melt flow indices of 2 g/10 min. The impact of electron irradiation at levels of 60, 120, and 180 kGy was studied. Four testing methods were employed as follows: wide-angle X-ray diffraction (WAXD); differential scanning calorimetry (DSC); dynamic mechanical analysis (DMA), using a high-temperature frequency sweep at 150 °C; and gel content analysis. The amount of crystalline phase was determined by WAXD and DSC. Copolymers with a higher VA content (EVA 212) had lower crystallinity. The increase in the amorphous phase allows for the greater movement of radicals, enabling them to react and form cross-links. The effects of the VA content, radiation dose, and frequency on dynamic mechanical properties were investigated by DMA. The DMA analysis focused on the shear storage modulus G, damping factor tanδ, and complex viscosity η*. After irradiation, the damping factor tanδ decreased with an increasing VA content, indicating improved elasticity and a higher degree of cross-linking. A gel content analysis was used to calculate the parameters of the Charlesby-Pinner and Charlesby–Rosiak equations, which help with the determination of the relationship between cross-linking and chain scission. The ratio of cross-linking to scission G(X)/G(S) was higher for the EVA with a higher VA content (EVA 212). Due to a higher VA content (12 wt.%), EVA 212 exhibits more efficient network formation.
