ABSTRACT A halogenated symmetrical formamidine, N,N′‐bis(3‐chloro‐4‐fluorophenyl)formamidine (FCF) was synthesized by the condensation reaction between triethyl orthoformate and 3‐chloro‐4‐fluoroaniline in 1:2 ratio. The compound FCF was characterized by FT‐IR, mass, NMR (1H and 13C) spectroscopic techniques and the purity was confirmed by elemental ...

Ammonia borane is considered a great hydrogen carrier, and when hydrolyzed, it can generate 3 moles of H2. This study highlights the combination of experimental and computational work, such as modeling and statistical analysis, that enables future experimentation by focusing on the parameter with the most profound effect on maximum H2 yield.

Abstract The German Research Foundation has established the priority program SPP 100+. Its subject is monitoring bridge structures in civil engineering. The data‐driven methods cluster deals with the use of measurements and their special global and local analysis methods, which complement each other in an overall multi‐scale concept in order to realize

Electronic and Magnetic Properties of Ferrous Iron in a True Square‐Planar Molecular Environment
Spin Hamiltonian parameters of an iron(II) phthalocyanine are obtained by pNMR, THz‐EPR, and quantum chemical calculations. Large zero field splitting and the peculiar g‐tensor pattern originate from mixing of the 3A2g ground state with two 3Eg‐excited states of almost the same energy. This forms the basis for correlations between magnetism, structure,
