However, the unknown active state of the catalyst and the lack of a defined catalytic mechanism preclude the design and optimization of suitable catalysts and reactor setups [...] External link: Fulltext 2018-02-1516:01 [PUBDB-2018-01217] Journal Article et al Determination of indium content of GaAs/(In,Ga)As/(GaAs) core-shell(-shell) nanowires by x-ray diffraction and nano x-ray fluorescence Physical review materials 2(1), 014604 (2018) [10.1103/PhysRevMaterials.2.014604]   We present two complementary approaches to investigate the In content in GaAs/(In,Ga)As/(GaAs) core-shell-(shell) nanowire (NW) heterostructures using synchrotron radiation. The key advantage of our methodology is that NWs are characterized in their as-grown configuration, i.e., perpendicularly standing on a substrate [...] OpenAccess: PDF PDF (PDFA); 2018-02-1509:33 [PUBDB-2018-01190] Conference Presentation Klassen, T. New Perspectives in Multi-Component Hydrides European Materials Research Society Fall Meeting Symposium O: Functional Hydride Materials, Meeting locationWarsaw, Poland, 19 Sep 2016 - 23 Sep 2016 Hydrogen technology can be incorporated into intermittent renewable energy systems to realise a complete clean, green energy harvesting and storage cycle. An efficient hydrogen storage system based on solid state hydrogen requires optimised material properties for each particular application.

The lytic properties of phage endolysins make them potential antibacterial agents for medical and industrial applications [...] OpenAccess: PDF PDF (PDFA); 2018-02-1210:33 [PUBDB-2018-01151] Journal Article et al Creep deformation of Co-Re-Ta-C alloys with varying C content – investigated in-situ by simultaneous synchrotron radiation diffraction Materials science and engineering / A XX, S0921509318301928 (2018) [10.1016/j.msea.2018.02.009]   The creep deformation of precipitation hardened Co-Re-Ta-C alloys is investigated during in-situ synchrotron diffraction experiment at 1373 K. At room temperature, the alloys have a structure consisting of ϵϵ-Co (hcp) and metastably retained γγ-Co (fcc) and are strengthened by precipitates of the mono-carbide of Ta, which are finely dispersed in the alloy matrix.

Bulk in situ high energy synchrotron X-ray diffraction is applied to follow continuously the evolution of the microstructure of the alloy during deformation and is complemented with metallographic analysis.

We show by high-resolution optical birefringence and synchrotron-based x-ray diffraction that confining a thermotropic discotic liquid crystal in cylindrical nanopores induces a quantized formation of annular layers consisting of concentric circular bent columns, unknown in the bulk state.
