A new method to compensate impedance artefacts for Li-ion batterieswith integrated micro-reference electrodes Electrochimica acta 259, 517 - 533 (2018) [10.1016/j.electacta.2017.10.132] In order to measure the electrochemical characteristics of both electrodes inside Li-ion batteries, micro-reference electrodes (μREF) turned out to be very useful. However, measuring the electrochemical impedance with respect to μREF can lead to severe measurement artefacts, making a detailed analysis of the impedance spectra complicated.

As a part of the materials characterisation program on Wf/W, we present the results of first tensile tests of as-fabricated Wf/W in this contribution.

Commercially available devices convert the measured magnetic fields into an apparent electrical conductivity (ECa), which can be shifted due to the presence of the operator and the system setup, e.g., GPS, cables, etc. [...] OpenAccess: PDF PDF (PDFA); 2017-12-0711:58 [FZJ-2017-08136] Contribution to a conference proceedings Zurek, M. Charge Symmetry Breaking In The dd→απ0 Reaction With WASA-at-COSY 26th International Nuclear Physics Conference, INPC2016, Meeting locationAdelaide, Australia, 11 Sep 2016 - 16 Sep 2016 PoS(INPC2016)310 (2017) OpenAccess: PDF PDF (PDFA); 2017-12-0711:09 [FZJ-2017-08134] Poster (Other) et al Evaluation of Non-negative matrix Factorization of grey matter in age prediction Annual Meeting of the Organization for Human Brain Mapping (OHBM), Meeting locationVancouver, Canada, 25 Jun 2017 - 29 Jun 2017 It has been shown that machine-learning methods applied to voxel-based morphometry (VBM) data allows the prediction of brain age [1]. Dimensionality reduction is a critical aspect of such brain-based prediction of phenotypical characteristics to counter the curse of dimensionality associated with voxel-wise analysis.

The crystal and magnetic structures well below the antiferromagnetic transition temperature of TN≈5.7 K were determined using neutron diffraction.

For the other molecular complex described (with bromanilic acid, dtBBP·BRA), no phase transitions have been observed between the liquid nitrogen temperature and the temperature of crystal decomposition.
