Frontiers of multiscale modeling and simulation.

It is not an exaggeration to say that Prof Wang has been responsible for Mol Sim's success in China since 2015. To celebrate Professor Wang's 80th birthday, we invited some prominent professors and researchers, who are also his good friends, to contribute their recent research results to this special issue. It is with great pleasure that we publish a special issue celebrating the 80th birthday of Professor Emeritus Wenchuan Wang of the college of chemical engineering, Beijing University of Chemical Engineering, China.
