The journal publishes the following types of papers: (a) original and important research;
(b) authoritative comprehensive reviews or short overviews of topics of current
interest; (c) brief but urgent communications on new significant research; and (d)
commentaries intended to foster the exchange of innovative or provocative ideas, and
to encourage dialogue, amongst researchers working in different cluster
1. Cluster Chemistry and Nanomaterials including main-group clusters, metal clusters, carbon- or silicon-based clusters, synthesis of molecular clusters, novel synthetic techniques for cluster growth and novel experimental techniques for cluster reactions, as well as structure determination, bonding analysis, chemical and physical properties of clusters (such as stoichiometric or catalytic reactivity, and dynamic processes). Other topics include clustering of atoms and molecules (); and self-assembly of clusters and nanoparticles (). Cluster materials may include nanomaterials, nanoparticles (), catalysts (), nanocomposites (), 1-D, 2-D, or 3-D arrays of nanomaterials, cluster-assembled hierarchical nanomaterials, cluster-based quasicrystals and intermetallic phases, and cluster-based sensors and detectors.
2. Cluster Physics and Astrophysics includes topics such as quantum confinement, Coulomb blockade, and tunneling of clusters or nanomaterials, physical properties of clusters (), gas-phase clusters, cluster beam, molecular or particle spectroscopy, single-particle () spectroscopies, transport properties (such as electrical and thermal conductivities, superconductors, superionic conductors, light transmission, and energy transport), quasicrystals, intermetallic phases, nonlinear phenomena (such as nonlinear optical properties, optical limiter, etc.), and chaos.
3. Cluster Biology and Life Sciences includes molecular biology of clusters, cluster cell biology, cluster biochemistry, formation and transport of clusters in biology, biomimetics, genetic clusters, dendrograms, cladograms, structures of viruses, sequence analysis, genome annotation, cancer clusters, cluster-based biosensors, detectors, and diagnostics.
4. Cluster Mathematics and Analysis includes topics such as cluster statistical analysis, new mathematical clustering algorithms, novel theoretical/computational methods for cluster calculations, or mathematical modeling or calculations of cluster structures, interactions, or properties.
5. Cluster-related Earth Science includes such topics as cluster formation in nature and clay nanoparticles (synthesis, structure, and properties).
6. Articles related to cluster-based energy production (renewable, solar, fossil, biomass, etc.), conversion, storage, or transport and to the use of clusters in environmental sciences are also welcome.
