I am an associate professor at the University of South Alabama. We study repulsive van der Waals interactions. Van der Waals interactions are dipole-dipole interactions. A dipole is composed of two poles, which are separatedwseparated by a distance. For example, an electric dipole is composed of a positive charge and a negative charge, which are separated by a distance r. Attractive van der Waals interactions can be used to create molecules. One type of molecule is called van der Waals molecules. We focus more on repulsive van der Waals interactions.
