  text: Indigoidine is a blue natural pigment, which can be efficiently synthetized
    in E. coli. In addition to its antioxidant and antimicrobial activities indigoidine
    due to its stability and deep blue color can find an application as an industrial,
    environmentally friendly dye. Moreover, similarly to its counterpart regular indigo
    dye, due to its molecular structure, indigoidine is an organic semiconductor.
    Fully conjugated aromatic moiety and intermolecular hydrogen bonding of indigoidine
    result in an unusually narrow bandgap for such a small molecule. This, in its
    turn, result is tight molecular packing in the solid state and opens a path for
    a wide range of application in organic and bio-electronics, such as electrochemical
    and field effect transistors, organic solar cells, light and bio-sensors etc.

  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 bottom-up assembly of colloidal nanocrystals is a versatile methodology
    to produce composite nanomaterials with precisely tuned electronic properties.
    Beyond the synthetic control over crystal domain size, shape, crystal phase, and
    composition, solution-processed nanocrystals allow exquisite surface engineering.
    This provides additional means to modulate the nanomaterial characteristics and
    particularly its electronic transport properties. For instance, inorganic surface
    ligands can be used to tune the type and concentration of majority carriers or
    to modify the electronic band structure. Herein, we report the thermoelectric
    properties of SnTe nanocomposites obtained from the consolidation of surface-engineered
    SnTe nanocrystals into macroscopic pellets. A CdSe-based ligand is selected to
    (i) converge the light and heavy bands through partial Cd alloying and (ii) generate
    CdSe nanoinclusions as a secondary phase within the SnTe matrix, thereby reducing
    the thermal conductivity. These SnTe-CdSe nanocomposites possess thermoelectric
    figures of merit of up to 1.3 at 850 K, which is, to the best of our knowledge,
    the highest thermoelectric figure of merit reported for solution-processed SnTe.

  text: In the present work, we detail a fast and simple solution-based method to
    synthesize hexagonal SnSe2 nanoplates (NPLs) and their use to produce crystallographically
    textured SnSe2 nanomaterials. We also demonstrate that the same strategy can be
    used to produce orthorhombic SnSe nanostructures and nanomaterials. NPLs are grown
    through a screw dislocation-driven mechanism. This mechanism typically results
    in pyramidal structures, but we demonstrate here that the growth from multiple
    dislocations results in flower-like structures. Crystallographically textured
    SnSe2 bulk nanomaterials obtained from the hot pressing of these SnSe2 structures
    display highly anisotropic charge and heat transport properties and thermoelectric
    (TE) figures of merit limited by relatively low electrical conductivities. To
    improve this parameter, SnSe2 NPLs are blended here with metal nanoparticles.
    The electrical conductivities of the blends are significantly improved with respect
    to bare SnSe2 NPLs, what translates into a three-fold increase of the TE Figure
    of merit, reaching unprecedented ZT values up to 0.65.
