This concerns, in particular, the formation of particle strings in the flow direction or hydroclusters, both important for the understanding of shear thinning and thickening phenomena [...] Restricted: PDF PDF (PDFA); External link: Fulltext 2017-07-1914:45 [PUBDB-2017-07989] Journal Article et al Disentangling magnetic order on nanostructured surfaces 2017-07-1216:39 [PUBDB-2017-07482] Journal Article et al In situ luminescence analysis: a new light on monitoring calcium phosphate phase transitions Inorganic chemistry frontiers 4(7), 1157 - 1165 (2017) [10.1039/C7QI00172J]   In this work, in situ luminescence analysis was applied for the first time for monitoring the phase transitions of calcium phosphate (CaP) and confirmed by synchrotron in situ X-ray diffraction in addition to in situ infrared spectroscopy, with simultaneous measurements of pH and ion conductivity. Applying doped Ce$^{3+}$ and Eu$^{3+}$ as local coordination sensors, the high sensitivity of their emission spectra upon the changes in the coordination sphere of the doped cation sites enabled to detect the formation of amorphous calcium phosphate (ACP) and Ca$_5$(PO$_4$)$_3$OH, besides their subsequent transitions to CaHPO$_4$·2H$_2$O and Ca$_8$H$_2$(PO$_4$)$_6$·5H$_2$O under real reaction conditions [...] OpenAccess: PDF PDF (PDFA); 2017-07-0610:41 [PUBDB-2017-06977] Journal Article et al Critical behavior of Mg$_{1–x}$Fe$_{x}$O at the pressure-induced iron spin-state crossover Physical review / B 95(21), 214412 (2017) [10.1103/PhysRevB.95.214412]   We present a high-pressure study of Mg$_{1–x}$Fe$_{x}$O (ferropericlase, Fp) single crystals 0.04(1)$\leqslant x \leqslant$ 0.33(1) with a focus on ferrous iron spin-state crossover and the material behavior preceding it. Using Vegard's law and highly accurate high-pressure single-crystal experimental data, we extract the lattice parameter $a^{HS}_{FeO}$ of the “FeO high spin lattice contribution” in the MgO-FeO solid solution.

The lattice compression of the rhombohedral crystal structure of R $\bar{3}$c symmetry is slightly anisotropic with anomaly in the pressure behavior of the c/a parameters ratio at P $\approx$ 20 GPa of presumably magnetic nature [...] Restricted: PDF PDF (PDFA); 2017-07-0116:38 [PUBDB-2017-06548] Journal Article et al Rapid cadmium SAD phasing at the standard wavelength (1Å) Acta crystallographica / D 73(7), 581 - 590 (2017) [10.1107/S2059798317006970]   Cadmium ions can be effectively used to promote crystal growth and for experimental phasing. Here, the use of cadmium ions as a suitable anomalous scatterer at the standard wavelength of 1 Å is demonstrated.

As more—and more specialized—spectrometers become available at many synchrotron radiation facilities, interest in pushing the limits of experimental energy resolution has increased [...] Restricted: PDF PDF (PDFA); 2017-06-2612:34 [PUBDB-2017-06090] Journal Article et al Nuclear Resonant Surface Diffraction of Synchrotron Radiation Physical review letters 118(23), 237204 (2017) [10.1103/PhysRevLett.118.237204]   Nuclear resonant x-ray diffraction in grazing incidence geometry is used to determine the lateral magnetic configuration in a one-dimensional lattice of ferromagnetic nanostripes. During magnetic reversal, strong nuclear superstructure diffraction peaks appear in addition to the electronic ones due to an antiferromagnetic order in the nanostripe lattice [...] OpenAccess: PDF PDF (PDFA); External link: Fulltext 2017-06-2310:06 [PUBDB-2017-05924] Journal Article et al Statistical properties of a free-electron laser revealed by Hanbury Brown?Twiss interferometry Physical review / A 95(2), 023843 (2017) [10.1103/PhysRevA.95.023843]   We present a comprehensive experimental analysis of statistical properties of the self-amplified spontaneous emission free-electron laser (FEL) FLASH by means of Hanbury Brown and Twiss interferometry. The experiments were performed at FEL wavelengths of 5.5, 13.4, and 20.8 nm [...] OpenAccess: PDF PDF (PDFA); 2017-06-2117:27 [PUBDB-2017-05801] Journal Article et al High-pressure behavior of $(Cs,K)Al_{4}Be_{5}B_{11}O_{28}$ (londonite): A single-crystal synchrotron diffraction study up to 26 GPa Journal of the American Ceramic Society xxxx, xxxx (2017) [10.1111/jace.14936]   The compressional behavior and the P-induced deformation mechanisms at theatomic scale of (Cs,K)Al4Be5B11O28(londonite, a ~7.31A and space groupP43m) were investigated by in situ single-crystal synchrotron X-ray diffractionwith a diamond anvil cell up to 26 GPa. No phase transition was observ ed withinthe P-range investigated: this material exhibits isotropi c compression (i.e., withcubic symmetry) in response to the applied pressure.
