Periodic Co/Nb pseudo spin valve for cryogenic memory
We present a study of magnetic structures with controllable effective exchange energy for Josephson switches and memory applications. As a basis for a weak link we propose to use a periodic structure composed of ferromagnetic (F) layers spaced by thin superconductors (s). [...]

Neutronic simulations for the FRM II
A new high density fuel element consisting of an alloy of uranium-molybdenum (UMo) is being developedfor the conversion of FRM II’s compact core from highly enriched uranium towards lower enricheduranium. Required slight changes of the core geometry demand both neutronic and thermal-hydraulicalre-calculations. [...]

Contrast Matched SANS for Observing SEI and Pore Clogging in Silicon-Graphite Anodes
Silicon-graphite (SiG) electrodes are attractive candidates as anodes for Li-ion batteries due to their high theoretical specific capacity.However, repeated lithiation/delithiation during charge/discharge cycling causes significant morphological changes of the siliconparticles. This results in the formation of highly porous silicon structures and severe side reactions at the silicon/electrolyte interface.To quantify these morphological changes, small-angle neutron scattering (SANS) was applied with selective contrast matching of Sinanoparticles (200 nm diameter) and the surrounding electrolyte decomposition products. [...]

In Situ Characterization at High Temperature of VDM Alloy 780 Premium to Determine Solvus Temperatures and Phase Transformations Using Neutron Diffraction and Small-Angle Neutron Scattering
TMS 2019 Annual Meeting & Exhibition, TMS2019, San Antonio, TexasSan Antonio, Texas, USA, 10 Mar 2019 - 14 Mar 20192019-03-102019-03-14 Cham : Springer International Publishing, The Minerals, Metals & Materials Series () [10.1007/978-3-030-05749-7_3]
New Ni-based superalloy VDM 780 Premium has been developed forhigher service temperatures than the alloy 718. This paper describes the properties ofthis alloy bymeans of in situ neutron diffraction (ND) and in situ small-angle neutronscattering (SANS)measurements supported by scanning electronmicroscopy (SEM)images.NDexperiments showthe phases present in the alloy and their evolutionwithtemperature, which allow us to derive their respective solvus temperatures and themisfit between the hardening phase and the matrix and its change with temperature..
