Impact of vanadium substitution on structural, magnetic, microwave absorption features and hyperfine interactions of SrCo hexaferrites

S. Caliskan et al.

Summary: The microstructure, morphology, magnetic features, hyperfine interactions, and oxidation state and chemical composition of Co-V co-substituted nano Sr-hexaferrite were investigated. The average crystallite size of the products was found to be in the range of 37-83 nm. The hexagonal morphology and chemical composition were observed and analyzed. The magnetization, coercivity, and microwave properties of the samples were also studied.

Modeling the vibrational spectroscopy of carbonmonoxymyoglobin using DFT and molecular dynamics

M. Esch et al.

Summary: Ultrafast vibrational spectroscopy is a valuable tool for studying dynamics on the sub-picosecond timescale. In this paper, the authors combine classical molecular dynamics simulations and density functional theory calculations to investigate the vibrational frequencies and spectroscopic properties of carbonmonoxymyoglobin. The results qualitatively agree with experimental observations and provide insights into the importance of different frequency contributions to spectroscopic observables.
