 2017-12-0809:33 [PUBDB-2017-12965] Journal Article et al Kinetic alteration of the $6Mg(NH_{2} )_{2}–9LiH–LiBH_{4}$ system by co-adding $YCl_{3}$ and $Li_{3}N$ Physical chemistry, chemical physics 19(47), 32105 - 32115 (2017) [10.1039/C7CP06826C]   The 6Mg(NH$_2$)$_2$–9LiH–LiBH$_4$ composite system has a maximum reversible hydrogen content of 4.2 wt% and a predicted dehydrogenation temperature of about 64 °C at 1 bar of H$_2$. However, the existence of severe kinetic barriers precludes the occurrence of de/re-hydrogenation processes at such a low temperature (H [...] 2017-12-0809:03 [PUBDB-2017-12953] Journal Article et al Sulfur-bearing metallic glasses: A new family of bulk glass-forming alloys Scripta materialia 146, 73 - 76 (2018) [10.1016/j.scriptamat.2017.11.011]   Metallic glasses constitute a class of engineering materials having an enormous potential for many fields of application due to their superior properties. Here, we report on a new family of sulfur-bearing bulk metallic glasses [...] Restricted: PDF PDF (PDFA); 2017-12-0801:56 [PUBDB-2017-12924] Journal Article et al Origin of shear induced β to ω transition in Ti–Nb-based alloys Acta materialia 92, 55 - 63 (2015) [10.1016/j.actamat.2015.03.040]   Ti–Nb-based alloys are essential materials for biomedical implant and aerospace applications. They reveal complex phase transformation behavior [...] Restricted: PDF PDF (PDFA); 2017-12-0719:34 [PUBDB-2017-12923] Journal Article et al Field-free deterministic ultrafast creation of magnetic skyrmions by spin–orbit torques Nature nanotechnology 12(11), 1040 - 1044 (2017) [10.1038/nnano.2017.178]   Magnetic skyrmions are stabilized by a combination of external magnetic fields, stray field energies, higher-order exchange interactions and the Dzyaloshinskii–Moriya interaction (DMI). The last favours homochiral skyrmions, whose motion is driven by spin–orbit torques and is deterministic, which makes systems with a large DMI relevant for applications.

Quantum phase transitions in $Ba_{(1−x)}Ca_{x}Fe_{12}O_{19}$ ( 0 ≤ x ≤ 0.10 ) Physical review / B 96(2), 024102 (2017) [10.1103/PhysRevB.96.024102]   The ground state of $Ba_{(1−x)}Ca_{x}Fe_{12}O_{19}$ (BFO) is controversial as three different quantum states, namely, quantum paraelectric, frustrated antiferroelectric, and quantum electric dipole liquid (QEDL), have been proposed. We have investigated the quantum critical behavior of BFO as a function of chemical pressure (a nonthermal variable) generated by smaller isovalent ion Ca$^{2+}$ at the Ba$^{2+}$ site [...] OpenAccess: PDF PDF (PDFA); 2017-12-0718:43 [PUBDB-2017-12921] Journal Article et al Incoherent Diffractive Imaging via Intensity Correlations of Hard X Rays Physical review letters 119(5), 053401 (2017) [10.1103/PhysRevLett.119.053401]   Established x-ray diffraction methods allow for high-resolution structure determination of crystals, crystallized protein structures, or even single molecules. While these techniques rely on coherent scattering, incoherent processes like fluorescence emission—often the predominant scattering mechanism—are generally considered detrimental for imaging applications.

Defence by Plant Toxins in Milkweed Bugs (Heteroptera: Lygaeinae) through the Evolution of a Sophisticated Storage Compartment Systematic entomology 42(1), 15-30 (2017) [10.1111/syen.12189]   Species of the heteropteran subfamily Lygaeinae possess special subcuticular compartments to store cardiac glycosides, plant-derived defensive compounds, which they release upon predator attack. In adults of the large milkweed bug, Oncopeltus fasciatus, these storage compartments have previously been described as a modified integument, forming a fluid-filled dorsolateral space.

Supercell simulations reveal instability towards the formation of nonuniform spin polarization in the Co-containing layers under tensile stress [...] OpenAccess: PDF PDF (PDFA); 2017-12-0717:18 [PUBDB-2017-12918] Journal Article et al Charge-Transfer-Induced Lattice Collapse in Ni-Rich NCM Cathode Materials during Delithiation The journal of physical chemistry / C 121(44), 24381-24388 (2017) [10.1021/acs.jpcc.7b06598]   Ni-rich $LiNi_xCo_yMn_zO_2$ (NCM) cathode materials have great potential for application in next-generation lithium-ion batteries owing to their high specific capacity. However, they are subjected to severe structural changes upon (de)lithiation, which adversely affects the cycling stability.

Strukturuntersuchungen an Flüssigkeitsgrenzflächen mittels Röntgenstreumethoden Kiel : Unibersitätsbibliothek Kiel, 159 pp. (2017) [10.3204/PUBDB-2017-12913] = Dissertation, Kiel University, 2017   Structural studies of liquid interfaces were performed using X-ray diffraction and X-ray reflectivity methods.The kinetics of the potential dependent growth of a crystalline PbBrF structure at the interface between a liquid mercury electrode and an aqueous electrolyte solution containing Br-, F- and Pb2+ were studied in situ by a combination of time-resolved X-ray diffraction and electrochemical methods.These measurements confirm the known reversible formation of a PbBrF monolayer at potentials positive of the lead (de)amalgamation equilibrium potential. The formation of PbBrF is driven by the oversaturation of the solution close to the interface due to a high Pb2+ concentration, which is a result of the lead deamalgamation.The rate of the monolayer formation increases with more positive potentials.The monolayer formation is followed by the quasi-epitaxial growth of a three-dimensional PbBrF phase.
