  text: Access to a blossoming library of colloidal nanomaterials provides building
    blocks for complex assembled materials. The journey to bring these prospects to
    fruition stands to benefit from the application of advanced processing methods.
    Epitaxially connected nanocrystal (or quantum dot) superlattices present a captivating
    model system for mesocrystals with intriguing emergent properties. The conventional
    processing approach to creating these materials involves assembling and attaching
    the constituent nanocrystals at the interface between two immiscible fluids. Processing
    small liquid volumes of the colloidal nanocrystal solution involves several complexities
    arising from the concurrent spreading, evaporation, assembly, and attachment.
    The ability of inkjet printers to deliver small (typically picoliter) liquid volumes
    with precise positioning is attractive to advance fundamental insights into the
    processing science, and thereby potentially enable new routes to incorporate the
    epitaxially connected superlattices into technology platforms. In this study,
    we identified the processing window of opportunity, including nanocrystal ink
    formulation and printing approach to enable delivery of colloidal nanocrystals
    from an inkjet nozzle onto the surface of a sessile droplet of the immiscible
    subphase. We demonstrate how inkjet printing can be scaled-down to enable the
    fabrication of epitaxially connected superlattices on patterned sub-millimeter
    droplets. We anticipate that insights from this work will spur on future advances
    to enable more mechanistic insights into the assembly processes and new avenues
    to create high-fidelity superlattices.

  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: 'The functional properties of quaternary I2–II–IV–VI4 nanomaterials, with
    potential interest in various technological fields, are highly sensitive to compositional
    variations, which is a challenging parameter to adjust. Here we demonstrate the
    presence of phosphonic acids to aid controlling the reactivity of the II element
    monomer to be incorporated in quaternary Cu2ZnSnSe4 nanoparticles and thus to
    provide a more reliable way to adjust the final nanoparticle metal ratios. Furthermore,
    we demonstrate the composition control in such multivalence nanoparticles to allow
    modifying charge carrier concentrations in nanomaterials produced from the assembly
    of these building blocks. '

  text: Mn3O4@CoMn2O4 nanoparticles (NPs) were produced at low temperature and ambient
    atmosphere using a one-pot two-step synthesis protocol involving the cation exchange
    of Mn by Co in preformed Mn3O4 NPs. Selecting the proper cobalt precursor, the
    nucleation of CoxOy crystallites at the Mn3O4@CoMn2O4 surface could be simultaneously
    promoted to form Mn3O4@CoMn2O4–CoxOy NPs. Such heterostructured NPs were investigated
    for oxygen reduction and evolution reactions (ORR, OER) in alkaline solution.
    Mn3O4@CoMn2O4–CoxOy NPs with [Co]/[Mn] = 1 showed low overpotentials of 0.31 V
    at −3 mA·cm–2 and a small Tafel slope of 52 mV·dec–1 for ORR, and overpotentials
    of 0.31 V at 10 mA·cm–2 and a Tafel slope of 81 mV·dec–1 for OER, thus outperforming
    commercial Pt-, IrO2-based and previously reported transition metal oxides. This
    cation-exchange-based synthesis protocol opens up a new approach to design novel
    heterostructured NPs as efficient nonprecious metal bifunctional oxygen catalysts.

  text: The present investigation confirms that initially implemented procedure to
    produce poly(methylidene malonate 2.1.2) (PMM 2.1.2) nanoparticles (Lescure et
    al. Pharm Res 1994;11:1270–77) lead to products mostly containing plasticizing
    oligomers which strongly lowered glass-transition temperature (Tg), dramatically
    reduced nanoparticle consistency and rendered them too sensitive to solubilization
    when diluted in an aqueous medium. From MALDI-TOF spectroscopy analysis, performed
    on intact colloids, emerged some structural information about these oligomeric
    species which could result from an intramolecular cyclization mechanism occurring
    soon in the course of the polymerization process. Thus, with the objective of
    overcoming these drawbacks, this contribution deals with the variations of manufacturing
    specifications such as pH and magnetic stirring speed to try and modulate molecular
    weight (Mw) of nanoparticle constituents and reduce oligomer concentration. Although
    the analyses performed on these new nanoparticles were rather encouraging, the
    colloid formation yield became so low that it required the developement of other
    methodologies, excluding a previous emulsion step, and allowing a controlled production
    of PMM 2.1.2-made nanoparticles having better physico-chemical characteristics
    while keeping good pharmaceutical capabilities.
