  text: Attachment of adhesive molecules on cell culture surfaces to restrict cell
    adhesion to defined areas and shapes has been vital for the progress of in vitro
    research. In currently existing patterning methods, a combination of pattern properties
    such as stability, precision, specificity, high-throughput outcome, and spatiotemporal
    control is highly desirable but challenging to achieve. Here, we introduce a versatile
    and high-throughput covalent photoimmobilization technique, comprising a light-dose-dependent
    patterning step and a subsequent functionalization of the pattern via click chemistry.
    This two-step process is feasible on arbitrary surfaces and allows for generation
    of sustainable patterns and gradients. The method is validated in different biological
    systems by patterning adhesive ligands on cell-repellent surfaces, thereby constraining
    the growth and migration of cells to the designated areas. We then implement a
    sequential photopatterning approach by adding a second switchable patterning step,
    allowing for spatiotemporal control over two distinct surface patterns. As a proof
    of concept, we reconstruct the dynamics of the tip/stalk cell switch during angiogenesis.
    Our results show that the spatiotemporal control provided by our “sequential photopatterning”
    system is essential for mimicking dynamic biological processes and that our innovative
    approach has great potential for further applications in cell science.

  text: In the present work, we report a solution-based strategy to produce crystallographically
    textured SnSe bulk nanomaterials and printed layers with optimized thermoelectric
    performance in the direction normal to the substrate. Our strategy is based on
    the formulation of a molecular precursor that can be continuously decomposed to
    produce a SnSe powder or printed into predefined patterns. The precursor formulation
    and decomposition conditions are optimized to produce pure phase 2D SnSe nanoplates.
    The printed layer and the bulk material obtained after hot press displays a clear
    preferential orientation of the crystallographic domains, resulting in an ultralow
    thermal conductivity of 0.55 W m–1 K–1 in the direction normal to the substrate.
    Such textured nanomaterials present highly anisotropic properties with the best
    thermoelectric performance in plane, i.e., in the directions parallel to the substrate,
    which coincide with the crystallographic bc plane of SnSe. This is an unfortunate
    characteristic because thermoelectric devices are designed to create/harvest temperature
    gradients in the direction normal to the substrate. We further demonstrate that
    this limitation can be overcome with the introduction of small amounts of tellurium
    in the precursor. The presence of tellurium allows one to reduce the band gap
    and increase both the charge carrier concentration and the mobility, especially
    the cross plane, with a minimal decrease of the Seebeck coefficient. These effects
    translate into record out of plane ZT values at 800 K.
