  text: AgSbSe2 is a promising thermoelectric (TE) p-type material for applications
    in the middle-temperature range. AgSbSe2 is characterized by relatively low thermal
    conductivities and high Seebeck coefficients, but its main limitation is moderate
    electrical conductivity. Herein, we detail an efficient and scalable hot-injection
    synthesis route to produce AgSbSe2 nanocrystals (NCs). To increase the carrier
    concentration and improve the electrical conductivity, these NCs are doped with
    Sn2+ on Sb3+ sites. Upon processing, the Sn2+ chemical state is conserved using
    a reducing NaBH4 solution to displace the organic ligand and anneal the material
    under a forming gas flow. The TE properties of the dense materials obtained from
    the consolidation of the NCs using a hot pressing are then characterized. The
    presence of Sn2+ ions replacing Sb3+ significantly increases the charge carrier
    concentration and, consequently, the electrical conductivity. Opportunely, the
    measured Seebeck coefficient varied within a small range upon Sn doping. The excellent
    performance obtained when Sn2+ ions are prevented from oxidation is rationalized
    by modeling the system. Calculated band structures disclosed that Sn doping induces
    convergence of the AgSbSe2 valence bands, accounting for an enhanced electronic
    effective mass. The dramatically enhanced carrier transport leads to a maximized
    power factor for AgSb0.98Sn0.02Se2 of 0.63 mW m–1 K–2 at 640 K. Thermally, phonon
    scattering is significantly enhanced in the NC-based materials, yielding an ultralow
    thermal conductivity of 0.3 W mK–1 at 666 K. Overall, a record-high figure of
    merit (zT) is obtained at 666 K for AgSb0.98Sn0.02Se2 at zT = 1.37, well above
    the values obtained for undoped AgSbSe2, at zT = 0.58 and state-of-art Pb- and
    Te-free materials, which makes AgSb0.98Sn0.02Se2 an excellent p-type candidate
    for medium-temperature TE applications.

  text: The self-assembly of nanoparticles driven by small molecules or ions may produce
    colloidal superlattices with features and properties reminiscent of those of metals
    or semiconductors. However, to what extent the properties of such supramolecular
    crystals actually resemble those of atomic materials often remains unclear. Here,
    we present coarse-grained molecular simulations explicitly demonstrating how a
    behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
    As a case study, we focus on gold nanoparticles bearing positively charged groups
    that self-assemble into FCC crystals via mediation by citrate counterions. In
    silico ohmic experiments show how the dynamically diverse behavior of the ions
    in different superlattice domains allows the opening of conductive ionic gates
    above certain levels of applied electric fields. The observed binary conductive/nonconductive
    behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular
    level, crossing the “band gap” requires a sufficient electrostatic stimulus to
    break the intermolecular interactions and make ions diffuse throughout the superlattice’s
    cavities.

  text: Cu2–xS and Cu2–xSe have recently been reported as promising thermoelectric
    (TE) materials for medium-temperature applications. In contrast, Cu2–xTe, another
    member of the copper chalcogenide family, typically exhibits low Seebeck coefficients
    that limit its potential to achieve a superior thermoelectric figure of merit,
    zT, particularly in the low-temperature range where this material could be effective.
    To address this, we investigated the TE performance of Cu1.5–xTe–Cu2Se nanocomposites
    by consolidating surface-engineered Cu1.5Te nanocrystals. This surface engineering
    strategy allows for precise adjustment of Cu/Te ratios and results in a reversible
    phase transition at around 600 K in Cu1.5–xTe–Cu2Se nanocomposites, as systematically
    confirmed by in situ high-temperature X-ray diffraction combined with differential
    scanning calorimetry analysis. The phase transition leads to a conversion from
    metallic-like to semiconducting-like TE properties. Additionally, a layer of Cu2Se
    generated around Cu1.5–xTe nanoparticles effectively inhibits Cu1.5–xTe grain
    growth, minimizing thermal conductivity and decreasing hole concentration. These
    properties indicate that copper telluride based compounds have a promising thermoelectric
    potential, translated into a high dimensionless zT of 1.3 at 560 K.

  text: SnSe has emerged as one of the most promising materials for thermoelectric
    energy conversion due to its extraordinary performance in its single-crystal form
    and its low-cost constituent elements. However, to achieve an economic impact,
    the polycrystalline counterpart needs to replicate the performance of the single
    crystal. Herein, we optimize the thermoelectric performance of polycrystalline
    SnSe produced by consolidating solution-processed and surface-engineered SnSe
    particles. In particular, the SnSe particles are coated with CdSe molecular complexes
    that crystallize during the sintering process, forming CdSe nanoparticles. The
    presence of CdSe nanoparticles inhibits SnSe grain growth during the consolidation
    step due to Zener pinning, yielding a material with a high density of grain boundaries.
    Moreover, the resulting SnSe–CdSe nanocomposites present a large number of defects
    at different length scales, which significantly reduce the thermal conductivity.
    The produced SnSe–CdSe nanocomposites exhibit thermoelectric figures of merit
    up to 2.2 at 786 K, which is among the highest reported for solution-processed
    SnSe.

  text: Cu2–xS has become one of the most promising thermoelectric materials for application
    in the middle-high temperature range. Its advantages include the abundance, low
    cost, and safety of its elements and a high performance at relatively elevated
    temperatures. However, stability issues limit its operation current and temperature,
    thus calling for the optimization of the material performance in the middle temperature
    range. Here, we present a synthetic protocol for large scale production of covellite
    CuS nanoparticles at ambient temperature and atmosphere, and using water as a
    solvent. The crystal phase and stoichiometry of the particles are afterward tuned
    through an annealing process at a moderate temperature under inert or reducing
    atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral
    crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal
    Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed
    in argon to transform to the cubic phase at ca. 400 K, while the material annealed
    in the presence of hydrogen undergoes two phase transitions, first to hexagonal
    and then to the cubic structure. The annealing atmosphere, temperature, and time
    allow adjustment of the density of copper vacancies and thus tuning of the charge
    carrier concentration and material transport properties. In this direction, the
    material annealed under Ar is characterized by higher electrical conductivities
    but lower Seebeck coefficients than the material annealed in the presence of hydrogen.
    By optimizing the charge carrier concentration through the annealing time, Cu2–xS
    with record figures of merit in the middle temperature range, up to 1.41 at 710
    K, is obtained. We finally demonstrate that this strategy, based on a low-cost
    and scalable solution synthesis process, is also suitable for the production of
    high performance Cu2–xS layers using high throughput and cost-effective printing
    technologies.

  text: Assemblies of colloidal semiconductor nanocrystals (NCs) in the form of thin
    solid films leverage the size-dependent quantum confinement properties and the
    wet chemical methods vital for the development of the emerging solution-processable
    electronics, photonics, and optoelectronics technologies. The ability to control
    the charge carrier transport in the colloidal NC assemblies is fundamental for
    altering their electronic and optical properties for the desired applications.
    Here we demonstrate a strategy to render the solids of narrow-bandgap NC assemblies
    exclusively electron-transporting by creating a type-II heterojunction via shelling.
    Electronic transport of molecularly cross-linked PbTe@PbS core@shell NC assemblies
    is measured using both a conventional solid gate transistor and an electric-double-layer
    transistor, as well as compared with those of core-only PbTe NCs. In contrast
    to the ambipolar characteristics demonstrated by many narrow-bandgap NCs, the
    core@shell NCs exhibit exclusive n-type transport, i.e., drastically suppressed
    contribution of holes to the overall transport. The PbS shell that forms a type-II
    heterojunction assists the selective carrier transport by heavy doping of electrons
    into the PbTe-core conduction level and simultaneously strongly localizes the
    holes within the NC core valence level. This strongly enhanced n-type transport
    makes these core@shell NCs suitable for applications where ambipolar characteristics
    should be actively suppressed, in particular, for thermoelectric and electron-transporting
    layers in photovoltaic devices.

  text: Methodologies that involve the use of nanoparticles as “artificial atoms”
    to rationally build materials in a bottom-up fashion are particularly well-suited
    to control the matter at the nanoscale. Colloidal synthetic routes allow for an
    exquisite control over such “artificial atoms” in terms of size, shape, and crystal
    phase as well as core and surface compositions. We present here a bottom-up approach
    to produce Pb–Ag–K–S–Te nanocomposites, which is a highly promising system for
    thermoelectric energy conversion. First, we developed a high-yield and scalable
    colloidal synthesis route to uniform lead sulfide (PbS) nanorods, whose tips are
    made of silver sulfide (Ag2S). We then took advantage of the large surface-to-volume
    ratio to introduce a p-type dopant (K) by replacing native organic ligands with
    K2Te. Upon thermal consolidation, K2Te-surface modified PbS–Ag2S nanorods yield
    p-type doped nanocomposites with PbTe and PbS as major phases and Ag2S and Ag2Te
    as embedded nanoinclusions. Thermoelectric characterization of such consolidated
    nanosolids showed a high thermoelectric figure-of-merit of 1 at 620 K.

  text: Nuclear pore complexes (NPCs) form gateways that control molecular exchange
    between the nucleus and the cytoplasm. They impose a diffusion barrier to macromolecules
    and enable the selective transport of nuclear transport receptors with bound cargo.
    The underlying mechanisms that establish these permeability properties remain
    to be fully elucidated but require unstructured nuclear pore proteins rich in
    Phe-Gly (FG)-repeat domains of different types, such as FxFG and GLFG. While physical
    modeling and in vitro approaches have provided a framework for explaining how
    the FG network contributes to the barrier and transport properties of the NPC,
    it remains unknown whether the number and/or the spatial positioning of different
    FG-domains along a cylindrical, ∼40 nm diameter transport channel contributes
    to their collective properties and function. To begin to answer these questions,
    we have used DNA origami to build a cylinder that mimics the dimensions of the
    central transport channel and can house a specified number of FG-domains at specific
    positions with easily tunable design parameters, such as grafting density and
    topology. We find the overall morphology of the FG-domain assemblies to be dependent
    on their chemical composition, determined by the type and density of FG-repeat,
    and on their architectural confinement provided by the DNA cylinder, largely consistent
    with here presented molecular dynamics simulations based on a coarse-grained polymer
    model. In addition, high-speed atomic force microscopy reveals local and reversible
    FG-domain condensation that transiently occludes the lumen of the DNA central
    channel mimics, suggestive of how the NPC might establish its permeability properties.

  text: One key goal of DNA nanotechnology is the bottom-up construction of macroscopic
    crystalline materials. Beyond applications in fields such as photonics or plasmonics,
    DNA-based crystal matrices could possibly facilitate the diffraction-based structural
    analysis of guest molecules. Seeman and co-workers reported in 2009 the first
    designed crystal matrices based on a 38 kDa DNA triangle that was composed of
    seven chains. The crystal lattice was stabilized, unprecedentedly, by Watson–Crick
    base pairing. However, 3D crystallization of larger designed DNA objects that
    include more chains such as DNA origami remains an unsolved problem. Larger objects
    would offer more degrees of freedom and design options with respect to tailoring
    lattice geometry and for positioning other objects within a crystal lattice. The
    greater rigidity of multilayer DNA origami could also positively influence the
    diffractive properties of crystals composed of such particles. Here, we rationally
    explore the role of heterogeneity and Watson–Crick interaction strengths in crystal
    growth using 40 variants of the original DNA triangle as model multichain objects.
    Crystal growth of the triangle was remarkably robust despite massive chemical,
    geometrical, and thermodynamical sample heterogeneity that we introduced, but
    the crystal growth sensitively depended on the sequences of base pairs next to
    the Watson–Crick sticky ends of the triangle. Our results point to weak lattice
    interactions and high concentrations as decisive factors for achieving productive
    crystallization, while sample heterogeneity and impurities played a minor role.

  text: Nature has long inspired scientists with its seemingly unlimited ability to
    harness solar energy and to utilize it to drive various physiological processes.
    With the help of man-made molecular photoswitches, we now have the potential to
    outperform natural systems in many ways, with the ultimate goal of fabricating
    multifunctional materials that operate at different light wavelengths. An important
    challenge in developing light-controlled artificial molecular machines lies in
    attaining a detailed understanding of the photoisomerization-coupled conformational
    changes that occur in macromolecules and molecular assemblies. In this issue of
    ACS Nano, Bléger, Rabe, and co-workers use force microscopy to provide interesting
    insights into the behavior of individual photoresponsive molecules and to identify
    contraction, extension, and crawling events accompanying light-induced isomerization.
