As soon as you taste it – evidence for sequential and parallel processing of gustatory information
eNeuro , ENEURO.0269-18.2018 - () [10.1523/ENEURO.0269-18.2018]
The quick and reliable detection and identification of a tastant in the mouth regulate nutrient uptake and toxin expulsion. Consistent with the pivotal role of the gustatory system, taste category information (e.g. [...]

Epitaxial GeSn: impact of process conditions on material quality
The electrical and optical material properties of epitaxial Ge1−xSnx and SiyGe1−x−ySnx are of high interest for novel device applications. However, the limited Sn solubility in Ge makes the epitaxial growth of Ge1−xSnx and SiyGe1−x−ySnx challenging. [...]

Spin-Resolved Electronic Response to the Phase Transition in MoTe 2
The semimetal MoTe2 is studied by spin- and angle-resolved photoemission spectroscopy across the centrosymmetry-breaking structural transition temperature of the bulk. A three-dimensional spin-texture is observed in the bulk Fermi surface in the low temperature, noncentrosymmetric phase that is consistent with first-principles calculations. [...]

Creep Behaviour of Dense and Porous SrTi0.75Fe0.25O3-δ for Oxygen Transport Membranes and Substrates
Considering the challenging conditions imposed by application of membranes in an asymmetric design, in particular creep resistance of the substrate material is an important parameter for the stability in long-term operation. As promising material, in terms of chemical stability, the perovskite SrTi0.75Fe0.25O3-δ has been identified in previous works. [...]

Invited Review Article: Multi-tip scanning tunneling microscopy: Experimental techniques and data analysis
Review of scientific instruments 89(10), 101101-1 - 101101-23 () [10.1063/1.5042346]
In scanning tunneling microscopy, we witness in recent years a paradigm shift from “just imaging” to detailed spectroscopic measurements at the nanoscale and multi-tip scanning tunneling microscope (STM) is a technique following this trend. It is capable of performing nanoscale charge transport measurements like a “multimeter at the nanoscale.” Distance-dependent four-point measurements, the acquisition of nanoscale potential maps at current carrying nanostructures and surfaces, as well as the acquisition of I − V curves of nanoelectronic devices are examples of the capabilities of the multi-tip STM technique. [...]

Reconstruction of the projected electrostatic potential in high-resolution transmission electron microscopy including phenomenological absorption
The projected electrostatic potential is reconstructed from a high-resolution exit wave function through a maximum-likelihood refinement algorithm. The theory of an already existing algorithm [1] is extended to include the effects of phenomenological absorption. [...]

Effective object planes for aberration-corrected transmission electron microscopy
In aberration-corrected transmission electron microscopy, the image contrast depends sensitively on the focus value. With the point resolution extended to an information limit of below 0.1 nm, even a focus change of as small as one nanometer could give a significant change in image contrast. [...]

The refractive index in electron microscopy and the errors of its approximations
In numerical calculations for electron diffraction often a simplified form of the electron-optical refractive index, linear in the electric potential, is used. In recent years improved calculation schemes have been proposed, aiming at higher accuracy by including higher-order terms of the electric potential. [...]

Understanding electron magnetic circular dichroism in a transition potential approach
This paper introduces an approach based on transition potentials for inelastic scattering to understand the underlying physics of electron magnetic circular dichroism (EMCD). The transition potentials are sufficiently localized to permit atomic-scale EMCD. [...]

Frequency and Hold Time Influence on Crack Growth Behavior of a 9–12% Cr Ferritic Martensitic Steel at Temperatures From 300 °C to 600 °C in air
Due to an increase of renewable energies proportion, e.g. wind power and photovoltaics, which cannot supply energy constantly, modern power plants must be able to be operated flexibly in order to compensate the residual load. [...]
