Journal ArticleDOI
Chemical surface alteration of biodegradable magnesium exposed to corrosion media
Regine Willumeit,Janine Fischer,Frank Feyerabend,Norbert Hort,Ulrich Bismayer,Stefanie Heidrich,Boriana Mihailova +6 more
TL;DR: In this paper, high-resolution electron-induced X-ray emission spectroscopy and infrared reflection microspectroscopy revealed a complex structure of the formed corrosion layer and the presence of CO(2) in concentrations close to that in blood is significant for the chemistry of the oxidised layer.
Journal ArticleDOI
Structural characterisation of X-ray amorphous calcium carbonate (ACC) in sternal deposits of the crustacea Porcellio scaber
Alexander Becker,Ulrich Bismayer,Matthias Epple,Helge Fabritius,Bernd Hasse,Jianmin Shi,Andreas Ziegler +6 more
TL;DR: In this paper, high-resolution X-ray diffraction, Xray absorption spectroscopy (EXAFS) and infrared microscopy were used to analyze land-based woodlice (crustacea, Porcellio scaber) mineral deposits.
Journal ArticleDOI
Analysis of short and long range atomic order in nanocrystalline diamonds with application of powder diffractometry
Bogdan F. Palosz,Ewa Grzanka,S. Stelmakh,Roman Pielaszek,Ulrich Bismayer,J. Neuefiend,H.-P. Weber,Thomas Proffen,R. VonDreele,Witold Palosz,Peter A. Curreri +10 more
TL;DR: In this paper, a tentative method of the analysis of powder diffraction patterns of nanocrystals is introduced which is based on the examination of the variation of lattice parameters calculated from individual Bragg lines (named the "apparent lattice parameter", alp).
Journal ArticleDOI
Hard mode spectroscopy : the concept and applications
TL;DR: Hard modes as mentioned in this paper are optically active phonons which show systematic changes of their Raman and/or IR spectra when the structural properties of a material are changed (e.g. by heating, application of pressure or chemical reactions).
Journal ArticleDOI
Structural phase transition in titanite, CaTiSiO 5 : A ramanspectroscopic study
TL;DR: The structural phase transition in titanite is correlated with a strong temperature dependence of Raman scattering cross sections and, to a somewhat lesser extent, with shifts of the phonon frequencies as mentioned in this paper.
