Special issue in commemoration of Wolfgang P. Meier A special issue of Macromolecular Rapid Communications has been published dedicated to Wolfgang P. Meier, who passed away in Janu- ary 2022. In the editorial of the journal, Nico Bruns, Corinne Nardin and Cornelia G. Palivan describe the career of Wolfgang Meier and list all the articles contributing to this special issue. In their text, they also make it clear what a wonderful person Wolfgang Meier was, with whom we all associate very positive memories.

Vibrations of molecules visualized and studied Researchers from the SNI network have developed a new method for imaging the vibration of molecules. The scientists, led by Professor Ernst Meyer from the Department of Physics at the University of Ba- sel, have studied a speci昀椀c pyrene molecule on a silver surface using a scanning tunneling microscope (STM). Understanding molecular vi- bration is of crucial importance in a wide range of areas in molecular electronics, spintronics or in the development of quantum comput- ers, since vibrations a昀昀ect transport properties and spin dynamics. The work was recently published in the scienti昀椀c journal “Nature Communications”.

If a positive voltage is then applied to the tip of an STM and brought close to the molecule, the molecule discharges.This discharge does not occur in one go, but rather in an oscillating manner.

Now, chemists at the Univer- sity of Basel have succeeded in replacing these rare elements with a signi昀椀cantly cheaper metal. In terms of their properties, the new materials are very similar to those used in the past.
