  text: <jats:title>Abstract</jats:title><jats:p>Most properties of solid materials
    are defined by their internal electric field and charge density distributions
    which so far are difficult to measure with high spatial resolution. Especially
    for 2D materials, the atomic electric fields influence the optoelectronic properties.
    In this study, the atomic‐scale electric field and charge density distribution
    of WSe<jats:sub>2</jats:sub> bi‐ and trilayers are revealed using an emerging
    microscopy technique, differential phase contrast (DPC) imaging in scanning transmission
    electron microscopy (STEM). For pristine material, a higher positive charge density
    located at the selenium atomic columns compared to the tungsten atomic columns
    is obtained and tentatively explained by a coherent scattering effect. Furthermore,
    the change in the electric field distribution induced by a missing selenium atomic
    column is investigated. A characteristic electric field distribution in the vicinity
    of the defect with locally reduced magnitudes compared to the pristine lattice
    is observed. This effect is accompanied by a considerable inward relaxation of
    the surrounding lattice, which according to first principles DFT calculation is
    fully compatible with a missing column of Se atoms. This shows that DPC imaging,
    as an electric field sensitive technique, provides additional and remarkable information
    to the otherwise only structural analysis obtained with conventional STEM imaging.</jats:p>

  text: <The replacement of noble metal catalysts by abundant iron as an active compound
    in CO oxidation is of ecologic and economic interest. However, improvement of
    their catalytic performance to the same level as state-of-the-art noble metal
    catalysts requires an in depth understanding of their working principle on an
    atomic level. As a contribution to this aim, a series of iron oxide catalysts
    with varying Fe loadings from 1 to 20 wt% immobilized on a γ-Al2O3 support is
    presented here, and a multidimensional structure–activity correlation is established.
    The CO oxidation activity is correlated to structural details obtained by various
    spectroscopic, diffraction, and microscopic methods, such as PXRD, PDF analysis,
    DRUVS, Mössbauer spectroscopy, STEM-EDX, and XAS. Low Fe loadings lead to less
    agglomerated but high percentual amounts of isolated, tetrahedrally coordinated
    iron oxide species, while the absolute amount of isolated species reaches its
    maximum at high Fe loadings. Consequently, the highest CO oxidation activity in
    terms of turnover frequencies can be correlated to small, finely dispersed iron
    oxide species with a large amount of tetrahedrally oxygen coordinated iron sites,
    while the overall amount of isolated iron oxide species correlates with a lower
    light-off temperature.

  text: <jats:p>Block copolymer (BCP) self-assembly is a promising tool for next generation
    lithography as microphase separated polymer domains in thin films can act as templates
    for surface nanopatterning with sub-20 nm features. The replicated patterns can,
    however, only be as precise as their templates. Thus, the investigation of the
    morphology of polymer domains is of great importance. Commonly used analytical
    techniques (neutron scattering, scanning force microscopy) either lack spatial
    information or nanoscale resolution. Using advanced analytical (scanning) transmission
    electron microscopy ((S)TEM), we provide real space information on polymer domain
    morphology and interfaces between polystyrene (PS) and polymethylmethacrylate
    (PMMA) in cylinder- and lamellae-forming BCPs at highest resolution. This allows
    us to correlate the internal structure of polymer domains with line edge roughnesses,
    interface widths and domain sizes. STEM is employed for high-resolution imaging,
    electron energy loss spectroscopy and energy filtered TEM (EFTEM) spectroscopic
    imaging for material identification and EFTEM thickness mapping for visualisation
    of material densities at defects. The volume fraction of non-phase separated polymer
    species can be analysed by EFTEM. These methods give new insights into the morphology
    of polymer domains the exact knowledge of which will allow to improve pattern
    quality for nanolithography.</jats:p>

  text: Zinc oxide (ZnO) hollow spheres with defined morphology and micro-/nanostructure
    are prepared by a hydrothermal synthesis approach. The materials possess fine-leaved
    structures at their particle surface (nanowall hollow micro spheres). Morphology
    control is achieved by citric acid used as an additive in variable relative quantities
    during the synthesis. The structure formation is studied by various time-dependent
    ex situ methods, such as scanning electron microscopy, x-ray diffraction, and
    Raman spectroscopy. The fine-leaved surface structure is characterized by high-resolution
    transmission electron microscopy techniques (HRTEM, STEM), using a high-angle
    annular dark field detector, as well as by differential phase contrast analysis.
    In-depth structural characterization of the nanowalls by drop-by-drop ex situ
    FE-SEM analysis provides insight into possible structure formation mechanisms.
    Further investigation addresses the thermal stability of the particle morphology
    and the enhancement of the surface-to-volume ratio by heat treatment (examined
    by N2 physisorption).

  text: "DNA origami nanostructures are versatile substrates for the controlled arrangement
    of molecular\r\ncapture sites with nanometer precision and thus have many promising
    applications in singlemolecule\r\nbioanalysis. Here, we investigate the adsorption
    of DNA origami nanostructures in\r\nnanohole arrays which represent an important
    class of biosensors and may benefit from the\r\nincorporation of DNA origami-based
    molecular probes. Nanoholes with well-defined diameter\r\nthat enable the adsorption
    of single DNA origami triangles are fabricated in Au films on Siwafers by nanosphere
    lithography. The efficiency of directed DNA origami adsorption on the\r\nexposed
    SiO2 areas at the bottoms of the nanoholes is evaluated in dependence of various\r\nparameters,
    i.e., Mg2+ and DNA origami concentrations, buffer strength, adsorption time, and\r\nnanohole
    diameter. We observe that the buffer strength has a surprisingly strong effect
    on DNA\r\norigami adsorption in the nanoholes and that multiple DNA origami triangles
    with 120 nm edge\r\nlength can adsorb in nanoholes as small as 120 nm in diameter.
    We attribute the latter\r\nobservation to the low lateral mobility of once adsorbed
    DNA origami on the SiO2 surface, in\r\ncombination with parasitic adsorption to
    the Au film. While parasitic adsorption can be\r\nsuppressed by modifying the
    Au film with a hydrophobic self-assembled monolayer, the limited\r\nsurface mobility
    of the adsorbed DNA origami still leads to poor localization accuracy in the\r\nnanoholes
    and results in many DNA origami crossing the boundary to the Au film even under\r\noptimized
    conditions. We discuss possible ways to minimize this effect by varying the\r\ncomposition
    of the adsorption buffer, employing different fabrication conditions, or using
    other\r\nsubstrate materials for nanohole array fabrication."

  text: "Bottom-up patterning techniques allow for the creation of surfaces with ordered
    arrays of nanoscale features\r\non large areas. Two bottom-up techniques suitable
    for the formation of regular nanopatterns on\r\ndifferent length scales are nanosphere
    lithography (NSL) and block copolymer (BCP) lithography. In this\r\npaper it is
    shown that NSL and BCP lithography can be combined to easily design hierarchically
    nanopatterned\r\nsurfaces of different materials. Nanosphere lithography is used
    for the pre-patterning of\r\nsurfaces with antidots, i.e. hexagonally arranged
    cylindrical holes in thin films of Au, Pt and TiO2 on SiO2,\r\nproviding a periodic
    chemical and topographical contrast on the surface suitable for templating in
    subsequent\r\nBCP lithography. PS-b-PMMA BCP is used in the second self-assembly
    step to form hexagonally\r\narranged nanopores with sub-20 nm diameter within
    the antidots upon microphase separation. To\r\nachieve this the microphase separation
    of BCP on planar surfaces is studied, too, and it is demonstrated\r\nfor the first
    time that vertical BCP nanopores can be formed on TiO2, Au and Pt films without
    using any\r\nneutralization layers. To explain this the influence of surface energy,
    polarity and roughness on the microphase\r\nseparation is investigated and discussed
    along with the wetting state of BCP on NSL-pre-patterned\r\nsurfaces. The presented
    novel route for the creation of advanced hierarchical nanopatterns is easily applicable\r\non
    large-area surfaces of different materials. This flexibility makes it suitable
    for a broad range of\r\napplications, from the morphological design of biocompatible
    surfaces for life science to complex\r\npre-patterns for nanoparticle placement
    in semiconductor technology."

  text: "Switchable two dimensional liquid crystal diffraction gratings are promising
    can-\r\ndidates in beam steering devices, multiplexers and holographic displays.
    For these areas of applications a high degree of integration in optical systems
    is much sought-after. In the context of diffraction gratings this means that the
    angle of diffraction should be rather high, which typically poses a problem as
    the fabrication of small grating periods is challenging. In this paper, we propose
    the use of nanosphere lithography (NSL) for the fabrication of two-dimensionally\r\nstructured
    electrodes with a periodicity of a few micrometers. NSL is based on the self-assembly
    of micro- or nanometer sized spheres into monolayers. It allows for easy substrate
    structuring on wafer scale. The manufactured electrode is combined with a liquid
    crystalline polymer-stabilized blue phase, which facilitates sub-millisecond electrical
    switching of the diffraction efficiency at adiffractionangle of 21.4°."
