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.

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. [...] 2018-02-1011:20 [PUBDB-2018-01146] Report/Journal Article et al An in situ investigation of the deformation mechanisms in a β-quenched Ti-5Al-5V-5Mo-3Cr alloy [I-20150533 EC] Materials science and engineering / A 717, 134 - 143 (2018) [10.1016/j.msea.2018.01.077]   The sequence of activation of deformation mechanisms in a near-β Ti-5Al-5Mo-5V-3Cr alloy quenched from the β-field is investigated as a function of strain during uniaxial compression at 0.001 s$^{−1}$ up to $ε$ = 0.041. 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.

Our experimental setup at PETRA III, P05, had a length of about 5 m consisting of an illumination optics, an imaging lens and a detector [...] OpenAccess: PDF PDF (PDFA); 2018-02-0811:04 [PUBDB-2018-01131] Journal Article et al Strain-dependent fractional molecular diffusion in humid spider silk fibres Interface 13(122), 20160506 - (2016) [10.1098/rsif.2016.0506]   Spider silk is a material well known for its outstanding mechanical properties, combining elasticity and tensile strength. The molecular mobility within the silk's polymer structure on the nanometre length scale importantly contributes to these macroscopic properties.

While propagation-based phase-contrast is an ideal tool to achieve highest resolution at a good contrast for almost not-absorbing material, it quickly comes to its limitations on applications demanding for a high dynamic range in contrast. [...] 2018-02-0810:48 [PUBDB-2018-01128] Journal Article et al Single and double grating-based X-ray microtomography using synchrotron radiation Applied physics letters 110(6), 061103 (2017) [10.1063/1.4975679]   Hard X-ray phase contrast imaging techniques have become most suitable for the non-destructive three-dimensional visualization of soft tissues at the microscopic level. Among the hard X-ray grating interferometry methods, a single-grating approach (XSGI) has been implemented by simplifying the established double-grating interferometer (XDGI).

Analytical registration of vertical image drifts in parallel beam tomographic data Optics letters 42(23), 4982-4985 (2017) [10.1364/OL.42.004982]   Reconstructing tomographic images of high resolution, as in x-ray microscopy or transmission electron microscopy, is often limited by the stability of the stages or sample drifts, which requires an image alignment prior to reconstruction. Feature-based image registration is routinely used to align images, but this technique relies on strong features in the sample or the application of gold tracer particles, for example.
