Cu6Sn5 intermetallic: Reconciling composition and crystal structure
TL;DR: In this paper, contradictory reports on the crystal structures and actual composition of the Cu6Sn5 intermetallic are explained by composition-dependent occurrence of the "classical" commensurately ordered η' phase and of an incommensurate ordered, more Cu-rich η phase.

Side-group engineering: The influence of norbornadienyl substituents on the properties of ethynylated pentacene and tetraazapentacene
Fabian Paulus,Michael Porz,Manuel Schaffroth,Frank Rominger,Andreas Leineweber,Yana Vaynzof,Uwe H. F. Bunz +6 more
TL;DR: In this paper, the effect of the substitution of a large norbornadienyl substituent at the silyl atom of the side chain was examined and their effect on the charge transport properties in organic field-effect transistors was investigated.

Dependence of the nitriding rate of ferritic and austenitic substrates on the crystallographic orientation of surface grains; gaseous nitriding of Fe-Cr and Ni-Ti alloys
Maryam Akhlaghi,Minsu Jung,Sai Ramudu Meka,Matej Fonovic,Andreas Leineweber,Eric J. Mittemeijer,Eric J. Mittemeijer +6 more
TL;DR: Gaseous nitriding of ferritic Fe-Cr and austenitic Ni-Ti solid solutions reveals that the extent of the uptake of dissolved nitrogen depends on the crystallographic orientation of the surface grains of the substrate.

Stacking disorder in metastable NiSn4
TL;DR: The atomic structure of NiSn4 intermetallic forming at ambient temperature in different types of Sn/Ni diffusion couples was investigated by powder X-ray diffraction as mentioned in this paper, showing that the stacking of these layers is irregular (faulted) by being an intermediate between the pseudotetragonal PtSn4- (space group Aeaa) and the tetragonal β-Irsn4-type (Space group I41/acd) ideal structures.

Ni3N compound layers produced by gaseous nitriding of nickel substrates; layer growth, macrostresses and intrinsic elastic anisotropy
Andreas Leineweber,F. Lienert,Shun Li Shang,Zi Kui Liu,Eric J. Mittemeijer,Eric J. Mittemeijer +5 more
TL;DR: In this article, Ni3N was prepared by gaseous nitriding of nickel substrates using gas mixtures of high nitrogen activities, composed of NH3 and H2 at 1 atm and at temperatures between 175 °C and 550 °C.
