 2018-11-1011:28 [FZJ-2018-05450] Journal Article et al Origin of Degradation in Si-Based All-Solid-State Li-Ion Microbatteries Advanced energy materials 8(30), 1801430 (2018) [10.1002/aenm.201801430] Like all rechargeable battery systems, conventional Li‐ion batteries (LIB) inevitably suffer from capacity losses during operation. This also holds for all‐solid‐state LIB.

The non-reciprocal nature of the dispersion manifests itself in a full asymmetry (non-reciprocity) of the dynamical structure factor S(q,E,μ$_0$H$_{int}$) with respect to flipping either the direction of the applied magnetic field μ$_0$H$_{int}$, the reduced momentum transfer q, or the energy transfer E..

Due to its high neutron attenuation, gadolinium (Gd) is the preferred material for grating fabrication, but suffers from difficulties with deposition time, stability, uniformity, and selectivity into high aspect ratio structures. [...] Restricted: PDF; 2018-10-2210:53 [IMPULSE-2018-00260] Journal Article et al In Situ Neutron Diffraction Study of Lithiation Gradients in Graphite Anodes during Discharge and Relaxation Missing Journal / Fehlende Zeitschrift 165(9), A1846 - A1856 (2018) [10.1149/2.1231809jes] Reduced capacity and rate capability at low temperature operation is a limiting factor for application of lithium-ion batteries in electro mobility. The visualization of electrode inhomogeneity resulting from low-temperature lithium transport limitations can illustrate the shortcomings of current electrode design.

The applicability of this effect is based on the prerequisite of the lamellar structure not being destroyed by external shear-fields.

There has also been considerable interest in magnetically‐functionalised microbubbles as multi‐modality imaging agents and carriers for targeted drug delivery.

New High Pressure Cells for Single Crystal Diffraction with Hot Neutrons at the Heinz Maier-Leibnitz Zentrum (MLZ) 2018 Workshop of the IUCr commission on high pressure, IUCr HP 2018, HonoluluHonolulu, USA, 29 Jul 2018 - 2 Aug 2018 2018-09-2811:28 [FZJ-2018-05445] Journal Article et al Uniaxial and hydrostatic pressure effects in α -RuCl 3 single crystals via thermal-expansion measurements Journal of physics / Condensed matter 30(38), 385702 - (2018) [10.1088/1361-648X/aada1e] We present high-resolution thermal-expansion and specific-heat measurements of single crystalline α-RuCl3. An extremely hysteretic structural transition expanding over 100 K is observed by thermal-expansion along both crystallographic axes, which we attribute to a change of stacking sequence of the RuCl3 layers.
