Hamiltonian decompositions of products of cycles
Discrete Mathematics, 1978 AbstractA graph is said to be decomposable into hamiltonian cycles if its edge set can be partitioned into hamiltonian cycles. We show that the cartesian product of any three cycles can be decomposed into three hamiltonian cycles, thus settling a conjecture by Kotzig.

ChemPhysChem, Accepted Article.Atomically dispersed Fe‐N‐C catalysts with high oxygen reduction reaction (ORR) activity have attracted great attention since the last decade. Due to its comparable ORR activity and low material cost, it is a promising platinum‐group metal (PGM) free catalyst that can replace the commercialized Pt/C materials; furthermore, it can facilitate the ...

ChemPhysChem, EarlyView.Five adamantyl esters and ethers with alkyl substituents of increasing branching are investigated by rotational spectroscopy. From the experimental data, their accurate structures are derived. All the derivatives feature similar CC distances, regardless of the functional group, the alkyl substituent, or other effects as methyl top internal rotation ...

ChemPhotoChem, EarlyView.Quantum chemistry has been used to investigate the key factors that determine the (reverse) intersystem crossing processes in boron‐based organic light‐emitting diode emitters. The ortho‐linked through‐space charge‐transfer compounds exhibit smaller singlet–triplet splittings than their para‐linked through‐bond charge‐transfer regioisomers.

Electrical Conductivities and Low Frequency Opacities in the Warm Dense Matter Regime
Contributions to Plasma Physics, EarlyView.ABSTRACT In this article, we examine different approaches for calculating low frequency opacities in the warm dense matter regime. The relevance of the average‐atom approximation and of different models for calculating opacities, such as the Ziman or Ziman–Evans models is discussed and the results compared to ab initio simulations.
