  text: By rigorously accounting for mesoscale spatial correlations in donor/acceptor
    surface properties, we develop a scale-spanning model for same-material tribocharging.
    We find that mesoscale correlations affect not only the magnitude of charge transfer
    but also the fluctuations—suppressing otherwise overwhelming charge-transfer variability
    that is not observed experimentally. We furthermore propose a generic theoretical
    mechanism by which the mesoscale features might emerge, which is qualitatively
    consistent with other proposals in the literature.

  text: Advances in shape-morphing materials, such as hydrogels, shape-memory polymers
    and light-responsive polymers have enabled prescribing self-directed deformations
    of initially flat geometries. However, most proposed solutions evolve towards
    a target geometry without considering time-dependent actuation paths. To achieve
    more complex geometries and avoid self-collisions, it is critical to encode a
    spatial and temporal shape evolution within the initially flat shell. Recent realizations
    of time-dependent morphing are limited to the actuation of few, discrete hinges
    and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding
    temporal shape evolution in architected shells that assume complex shapes and
    doubly curved geometries. The shells are non-periodic tessellations of pre-stressed
    contractile unit cells that soften in water at rates prescribed locally by mesostructure
    geometry. The ensuing midplane contraction is coupled to the formation of encoded
    curvatures. We propose an inverse design tool based on a data-driven model for
    unit cells’ temporal responses.

  text: In the quest for alternate and efficient electrode materials, ternary metal
    electrocatalysts (TMEs), part of the perovskite family, were synthesized and tested
    for methanol electro-oxidation in alkaline media. La0.5Ca0.5MO3 (M = Ni, Co, or
    Mn) was synthesized via sol-gel method. X-ray diffraction analysis revealed that
    the perovskite crystal structure possesses characteristic sharp and crystalline
    peaks for all synthesized ternary electrocatalysts. The average particle size
    calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO)
    > La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as
    prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The
    qualitative and quantitative analysis revealed the presence of La, Ca and Co in
    parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82%
    respectively. The particle size distribution was homogenous, as determined by
    scanning electron and transmission electron microscopes. The electrocatalytic
    activity of the synthesized ternary electrocatalysts was studied electrochemically
    by cyclic voltammetry. The calculated diffusion coefficient values showed that
    electrode surface of LCNO and LCCO have limited efficiency for diffusion related
    phenomenon. The heterogeneous rate constants inferred better electrode kinetics
    of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic
    peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V,
    respectively. Methanol electro-oxidation was found minimal in case of LCMO sample.
    We have observed that Co substitution at B-site of perovskite electrode materials
    attains better electrochemical properties, thus in relation with reported literature.
