In contrast to steel‐based reaction cells, sapphire or quartz glass cells show no blind activity [...] 2018-11-0615:26 [PUBDB-2018-04213] Journal Article et al Thermal behavior, structural relaxation and magnetic study of a new Hf-microalloyed Co-based glassy alloy with high thermal stability Journal of alloys and compounds 748, 553 - 560 (2018) [10.1016/j.jallcom.2018.03.199]   In the present work, the influence of a minor Hf addition on the atomic structure, crystallization behavior, thermal stability and magnetic properties of a Co-based metallic glass was studied. Thermal analysis indicates that the thermal stability of new glassy ribbons microalloyed with 2.5 at.% Hf is notably enhanced through increasing the incubation time prior to devitrification and enlarging the width of the supercooled liquid region from 72 K to 96 K [...] 2018-11-0615:25 [PUBDB-2018-04212] Journal Article et al Structural evolution in a metallic glass pillar upon compression   The in-situ observation of structural evolution of a metallic glass pillar during deformation is carried out in a high energy synchrotron X-ray source. The changes of the first maximum in structure factor, S(q), reveal the evolution of atomic structure upon stress [...] 2018-11-0614:28 [PUBDB-2018-04199] Book/Report/Internal Report et al RRR degradation and gas absorption in the electron beam welding area of high purity niobium [TESLA Report 2003-07] TESLA Reports 13 pp. (2003) [10.1063/1.1597366]   Experiences concerning RRR degradation and gas absorption of high purity niobium welded at different electron beam (EB) facilities are summarized. The oxygen and nitrogen content is increased as a rule at the welding seam.

The results show that the normal of mother lamellae in a spherulite is aligned mainly perpendicular to the radius, and the subsidiary daughter lamellae are inclined 80.75° with respect to that of the dominant mother lamellae [...] 2018-11-0212:10 [PUBDB-2018-04131] Journal Article et al Critical Strains for Lamellae Deformation and Cavitation during Uniaxial Stretching of Annealed Isotactic Polypropylene Macromolecules 51(16), 6276 - 6290 (2018) [10.1021/acs.macromol.8b00642]   The lamellae deformation and cavitation behavior of annealed isotactic polypropylene during uniaxial stretching are comprehensively investigated by in situ synchrotron small-angle X-ray scattering and wide-angle X-ray scattering. We reveal how lamellae deformation occurs in the time scales of elastic deformation, intralamellar slip, and melting–recrystallization, separated by three critical strains which are only rarely influenced by annealing [...] Restricted: PDF PDF (PDFA); 2018-10-3009:01 [PUBDB-2018-04012] Journal Article et al SLC30A10 Mutation Involved in Parkinsonism Results in Manganese Accumulation within Nanovesicles of the Golgi Apparatus ACS chemical neuroscience in press, acschemneuro.8b00451 (2018) [10.1021/acschemneuro.8b00451]   Restricted: PDF PDF (PDFA); External link: Fulltext 2018-10-2322:15 [PUBDB-2018-03898] Journal Article et al Unravelling the structural rearrangement of polymer colloidal crystals under dry sintering conditions Soft matter 14(33), 6849 - 6856 (2018) [10.1039/C8SM01412D]   The structural rearrangement of polystyrene colloidal crystals under dry sintering conditions has been revealed by in situ grazing incidence X-ray scattering. The measured diffraction patterns were analysed using distorted wave Born approximation (DWBA) theory and the structural parameters of the as-grown colloidal crystals of three different particle sizes were determined for the in-plane and out-of-plane directions in a film [...] Restricted: PDF PDF (PDFA); 2018-10-2214:33 [PUBDB-2018-03875] Journal Article et al Pressure-induced modifications of the magnetic order in the spin-chain compound $\mathrm{Ca_{3}Co_{2}O_{6}}$ Physical review / B 98(13), 134435 (2018) [10.1103/PhysRevB.98.134435]   The structural and magnetic properties of the $\mathrm{Ca_{3}Co_{2}O_{6}}$ spin-chain compound have been studied by means ofneutron and x-ray powder diffraction at pressures up to 6.8 and 32 GPa, respectively. A suppression of the initialspin-density wave state $(T_{N} = 25 K)$ and stabilization of the collinear commensurate antiferromagnetic (AFM)state at high pressures $(T_{NC} = 26 K at P = 2.1$ GPa) were observed.

Selected structural parameters related to lithium concentrations in the positive and negative electrodes were determined averaging over cell thickness on a 1 × 1 mm$^2$ grid, thus resembling an experimental radiography technique with a pixel size of 1 mm$^2$, where the diffraction signal is used instead of attenuation of the photon beam [...]
