 2018-06-2108:42 [PUBDB-2018-02339] Journal Article et al Nano-laminated thin film metallic glass design for outstanding mechanical properties Scripta materialia 155, 73 - 77 (2018) [10.1016/j.scriptamat.2018.06.015]   We report the enhancement of fracture toughness and strength of a cobalt tantalum-based metallic glass thinfilm with increasing boron content. The improvement of the mechanical performance is attributed to the formationof a compositionally lamellar compared to uniform glass microstructure, which becomes thinner with increasingboron content as revealed by transmission electron microscopy.

Detailed superconducting quantum interference device measurements reveal a complex phase diagram with five distinct magnetic phases [...] OpenAccess: PDF PDF (PDFA); 2018-06-1913:02 [PUBDB-2018-02329] Journal Article et al Probing the Thermochromic Phase Transition in $\mathrm{CuMoO_{4}}$ by EXAFS Spectroscopy Physica status solidi / B 255, 1800074 (2018) [10.1002/pssb.201800074]   Extended X-ray absorption fine structure (EXAFS) spectroscopy at the Mo K-edge is used to follow the thermochromic γ-to-α phase transition in copper molybdate (CuMoO4). The temperature dependence (10–300 K) of the radial distribution function (RDF) for the Mo–O atom pairs in the first coordination shell of molybdenum atoms is reconstructed by the regularization-like method from the experimental EXAFS spectra.

The FeNC catalysts were synthesized from different nitrogen precursors and, as a result of this, exhibited quite distinct physical properties, such as BET surface areas and distinct chemical N-functionalities in varying ratios.

Our investigations indicate that the starting $Pbnm$ phase of $\mathrm{LiFePO_{4}}$ persists up to 70 GPa [...] Fulltext: PDF PDF (PDFA); OpenAccess: PDF PDF (PDFA); 2018-06-1709:25 [PUBDB-2018-02309] Journal Article et al High-pressure synthesis of a nitrogen-rich inclusion compound ReN8·xN2 with conjugated polymeric nitrogen chains   Abstract: A nitrogen-rich compound, ReN8·xN2, was synthesizedby a direct reaction between rhenium and nitrogen at highpressure and high temperature in a laser-heated diamond anvilcell. Single-crystal X-ray diffraction revealed that the crystalstructure, which is based on the ReN8 framework, hasrectangular-shaped channels that accommodate nitrogen molecules.Thus, despite a very high synthesis pressure, exceeding100 GPa, ReN8·xN2 is an inclusion compound.

A new model using permeabilised/skinned porcine longissimus thoracis et lumborum muscle fibres was established to study effects of varied pH, temperature and the presence of rigor bonds on the muscle fibre structure [...] 2018-06-0712:54 [PUBDB-2018-02215] Journal Article et al Role of relative humidity and Cd/Zn stoichiometry in the photo-oxidation process of cadmium yellows $(CdS/Cd_{1-x}Zn_{x}S)$ in oil paintings 2018-06-0616:45 [PUBDB-2018-02213] Journal Article et al Comparative study of the luminescent properties of oxide compounds under synchrotron radiation excitation: $\mathrm{Lu_2O_3:Eu}$ nanopowders, ceramics and films Journal of luminescence 199, 461 - 464 (2018) [10.1016/j.jlumin.2018.03.044]   The paper is dedicated to the comparative study of the luminescent properties of Lu$_2$O$_3$:Eu (5%) nanopowders, ceramics and film samples using excitation by the synchrotron radiation in the range of the fundamental absorption edge of Lu$_2$O$_3$ host. The luminescence of F$^+$ centers in the band peaked at 400 nm with a lifetime about of 1.4 ns was observed in Lu$_2$O$_3$:Eu nanopowder [...] Restricted: PDF PDF (PDFA); External link: Fulltext 2018-06-0614:21 [PUBDB-2018-02210] Journal Article et al Structural dynamics upon photoexcitation-induced charge transfer in a dicopper($\mathrm{_I}$)–disulfide complex Physical chemistry, chemical physics 20(9), 6274 - 6286 (2018) [10.1039/C7CP04880G]   The structural dynamics of charge-transfer states of nitrogen-ligated copper complexes has been extensively investigated in recent years following the development of pump–probe X-ray techniques. In this study we extend this approach towards copper complexes with sulfur coordination and investigate the influence of charge transfer states on the structure of a dicopper(I) complex with coordination by bridging disulfide ligands and additionally tetramethylguanidine units [Cu$^{I}$$_{2}$(NSSN)$_2$]$^{2+}$ [...] OpenAccess: authorreprints - PDF PDF (PDFA); c7cp04880g - PDF PDF (PDFA);
