International Symposium on Small Particles and Inorganic Clusters


September 3rd-8th, 2023

Berlin, Germany


Confirmed Invited Speakers (*)

We cordially invite you to participate in the next conference of the ISSPIC series that will take place in the vibrant city of Berlin, Germany, from September 3rd to September 8th, 2023. It will be organized as a real symposium with all talks and poster sessions in presence. In addition, we are planning a pre-workshop (September 2nd to 3rd) for graduate students with possibilities to win a hot topic slot in the ISSPIC conference.

The objective of the conference is to be an interdisciplinary forum for presentation and discussion of fundamental and technological developments in the research fields involving finite size effects of materials at the nanometer scale. The symposium aims to provide an overview of new results, emerging trends, and perspectives in the science of atomic and molecular clusters, nanoparticles, and nanostructures.

The ISSPIC XXI deals with...

  • atomic and molecular clusters
  • nanoparticles/nanocrystals
  • supported and embedded clusters and nanoparticles
  • clusters and nanoparticle assemblies
  • nanodroplets/superfluidity
  • other emerging nano scale systems

...and studies

  • structures and thermodynamics
  • electronic structure and quantum effects
  • spectroscopy and dynamics
  • cluster and nanoparticle reactivity
  • single and few atom cluster catalysis
  • correlated electrons: magnetism, superconductivity
  • optical properties and plasmonics
  • 2D-materials, carbon-based nanoparticles, nanodiamonds
  • biotechnological and medical applications
  • environmental science
  • devices and applications
  • energy-related topics

The local organization team is very much looking forward to welcoming you in Berlin in September 2023.

Thorsten M. Bernhardt (Chair), Thomas Möller (Co-Chair), Karl-Heinz Meiwes-Broer (Co-Chair)
Wolfgang Christen, Otto Dopfer, André Fielicke, Sandra M. Lang, Tobias Lau, Andrea Merli, and Jürgen P. Rabe.

Invited speakers, conference participants, and everyone interested in the scientific subject of the ISSPIC are strongly encouraged and very welcome to contribute with a peer reviewed paper to a themed collection on the subject “Size effects in the chemistry and physics of atomic and molecular clusters, nanoparticles and nanostructures” (to be published in PCCP - more information here). The issue will be hosted by the guest editors André Fielicke, Sandra Lang, and Thorsten Bernhardt.
