Summary:Helium droplets provide an exotic and unique environment for the study of physical and chemical phenomena. Properties of these droplets include a low temperature (0.37 K), their superfluidity, and the ability to easily add a wide variety of atoms and molecules. This tutorial review provides a concise account of the basic principles of helium droplets, including how to form, dope, and interrogate these objects. There then follows a series of selected applications grouped under particular themes, with strong bias towards topics likely to be of particular interest to chemists. This review provides an overview of research performed on doped helium nanodroplets with a bias towards applications in chemistry.
Bibliography:Shengfu Yang obtained his PhD in 1997 from the University of Science and Technology of China under the supervision of Prof. Qingshi Zhu. He then undertook postdoctoral work at the Massachusetts Institute of Technology (USA), the University of Helsinki (Finland) and the University of Leicester. He was awarded a UK EPSRC Advanced Research Fellowship in 2006 and was appointed as a senior lecturer in nanochemistry in 2011. His research interests involve spectroscopic and mass spectrometric investigation of molecules and molecular clusters, the synthesis of novel nanoparticles using superfluid helium nanodroplets, and their characterisation and applications.
Andrew Ellis obtained his PhD degree from the University of Southampton working with John Dyke. In 1989 he joined Terry A. Miller's research group at Ohio State University as a NATO/SERC postdoctoral fellow, investigating free radicals using laser spectroscopy. He returned to the U.K. in 1991, taking up an academic post at the University of Leicester. His research interests include the spectroscopy and dynamics of molecules and clusters in the gas phase and in helium nanodroplets, the growth of nanoparticles in helium droplets, and the development of new mass spectrometric techniques for the analysis of trace organic compounds.
