This Virtual Issue is dedicated to the scientific accomplishments of Helmuth Möhwald (1946-2018). In addition to his own highly notable scientific achievements, Möhwald fostered the growth of a variety of research topics within interface science. Further, though his focus was on fundamental research, he never forgot the link to potential applications. Explored by Helmuth and coworkers, this includes new approaches in X-ray diffraction at liquid surfaces; introduction and advancement of LbL technique; functional colloids; development of nanocapsules; stimuli-sensitive microgels; and Pickering emulsions.
Accompanying this Virtual Issue is a Special Issue of the same name. The Langmuir issue is made up of Feature Articles contributed by a handful of Möhwald’s former coworkers, each article highlighting a current research direction that was initiated through prior collaboration with Möhwald, but the focus of this Virtual Issue is retrospective. In partnership with ACS Nano and Journal of Physical Chemistry B and C, Langmuir to highlight 11 previous publications that exemplify the development of the different research topics generated in collaboration with Helmuth Möhwald.
