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.","lang":"eng"}],"issue":"12","article_processing_charge":"No","volume":17,"publication_status":"published"},{"abstract":[{"lang":"eng","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."}],"_id":"13346","date_published":"2023-01-10T00:00:00Z","article_processing_charge":"No","issue":"1","volume":17,"oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1021/acsnano.2c07558"}],"publication_status":"published","year":"2023","oa_version":"Published Version","article_type":"original","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-08-02T06:51:15Z","date_created":"2023-08-01T09:30:29Z","month":"01","extern":"1","page":"275-287","status":"public","intvolume":"        17","publication":"ACS Nano","quality_controlled":"1","publisher":"American Chemical Society","type":"journal_article","author":[{"full_name":"Lionello, Chiara","first_name":"Chiara","last_name":"Lionello"},{"first_name":"Claudio","full_name":"Perego, Claudio","last_name":"Perego"},{"full_name":"Gardin, Andrea","first_name":"Andrea","last_name":"Gardin"},{"id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","last_name":"Klajn","first_name":"Rafal","full_name":"Klajn, Rafal"},{"last_name":"Pavan","first_name":"Giovanni M.","full_name":"Pavan, Giovanni M."}],"day":"10","title":"Supramolecular semiconductivity through emerging ionic gates in ion–nanoparticle superlattices","citation":{"chicago":"Lionello, Chiara, Claudio Perego, Andrea Gardin, Rafal Klajn, and Giovanni M.

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.","lang":"eng"}],"date_published":"2023-05-09T00:00:00Z","publication_status":"published","volume":17},{"publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-02T14:41:05Z","external_id":{"isi":["000767223400008"],"pmid":["34549956"]},"scopus_import":"1","oa_version":"Published Version","year":"2022","has_accepted_license":"1","article_type":"original","oa":1,"publication_status":"published","volume":16,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2022-03-02T16:17:29Z","issue":"1","article_processing_charge":"Yes (via OA deal)","_id":"10042","date_published":"2022-01-25T00:00:00Z","abstract":[{"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.

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.

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.","lang":"eng"}],"article_processing_charge":"No","issue":"3","volume":15,"publication_status":"published","main_file_link":[{"open_access":"1","url":"https://upcommons.upc.edu/bitstream/handle/2117/363528/Pb%20mengyao.pdf?sequence=1&isAllowed=y"}],"oa":1,"day":"01","author":[{"last_name":"Li","full_name":"Li, Mengyao","first_name":"Mengyao"},{"full_name":"Liu, Yu","first_name":"Yu","last_name":"Liu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7313-6740"},{"first_name":"Yu","full_name":"Zhang, Yu","last_name":"Zhang"},{"last_name":"Han","full_name":"Han, Xu","first_name":"Xu"},{"last_name":"Zhang","full_name":"Zhang, Ting","first_name":"Ting"},{"full_name":"Zuo, Yong","first_name":"Yong","last_name":"Zuo"},{"last_name":"Xie","full_name":"Xie, Chenyang","first_name":"Chenyang"},{"last_name":"Xiao","first_name":"Ke","full_name":"Xiao, Ke"},{"last_name":"Arbiol","full_name":"Arbiol, Jordi","first_name":"Jordi"},{"last_name":"Llorca","full_name":"Llorca, Jordi","first_name":"Jordi"},{"last_name":"Ibáñez","first_name":"Maria","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5013-2843"},{"first_name":"Junfeng","full_name":"Liu, Junfeng","last_name":"Liu"},{"full_name":"Cabot, Andreu","first_name":"Andreu","last_name":"Cabot"}],"type":"journal_article","citation":{"mla":"Li, Mengyao, et al. “Effect of the Annealing Atmosphere on Crystal Phase and Thermoelectric Properties of Copper Sulfide.” <i>ACS Nano</i>, vol. 15, no. 3, American Chemical Society , 2021, pp. 4967–4978, doi:<a href=\"https://doi.org/10.1021/acsnano.0c09866\">10.1021/acsnano.0c09866</a>.","ista":"Li M, Liu Y, Zhang Y, Han X, Zhang T, Zuo Y, Xie C, Xiao K, Arbiol J, Llorca J, Ibáñez M, Liu J, Cabot A. 2021.

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.","lang":"eng"}],"file":[{"date_updated":"2020-07-14T12:47:33Z","access_level":"open_access","file_name":"2019_ACSNano_Ibanez.pdf","file_size":8628690,"creator":"dernst","date_created":"2019-07-16T14:17:09Z","content_type":"application/pdf","relation":"main_file","file_id":"6644"}],"oa":1,"publication_status":"published","volume":13,"file_date_updated":"2020-07-14T12:47:33Z","year":"2019","has_accepted_license":"1","oa_version":"Published Version","article_type":"original","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_updated":"2023-08-28T12:20:53Z","external_id":{"pmid":["31185159"],"isi":["000473248300043"]},"scopus_import":"1","page":"6572-6580","date_created":"2019-06-18T13:54:34Z","month":"06","isi":1,"publisher":"American Chemical Society","intvolume":"        13","status":"public","department":[{"_id":"MaIb"}],"quality_controlled":"1","publication":"ACS Nano","title":"Tuning transport properties in thermoelectric nanocomposites through inorganic ligands and heterostructured building blocks","ec_funded":1,"citation":{"ama":"Ibáñez M, Genç A, Hasler R, et al.

However, the structural motifs and their precise role for long-range conductivity are yet to be explored. Here, we present a comprehensive structural picture of a perylene bisimide hydrogel, suggesting that its long-range conductivity is limited by charge transfer between electronic backbones. We reveal nanocrystalline ribbon-like structures as the electronic and structural backbone units between which charge transfer is mediated by polar solvent bridges.

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.","lang":"eng"}],"issue":"2","article_processing_charge":"No","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2021-11-26T15:57:02Z","scopus_import":"1","external_id":{"pmid":["29350911"]},"year":"2018","oa_version":"None","article_type":"original"},{"_id":"14302","abstract":[{"lang":"eng","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."}],"date_published":"2016-09-01T00:00:00Z","article_processing_charge":"No","issue":"10","volume":10,"publication_status":"published","oa_version":"None","year":"2016","article_type":"original","publication_identifier":{"eissn":["1936-086X"],"issn":["1936-0851"]},"external_id":{"pmid":["27583560"]},"scopus_import":"1","date_updated":"2023-11-07T12:08:46Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_created":"2023-09-06T12:52:00Z","month":"09","extern":"1","page":"9156-9164","status":"public","intvolume":"        10","publication":"ACS Nano","quality_controlled":"1","publisher":"American Chemical Society","author":[{"last_name":"Stahl","full_name":"Stahl, Evi","first_name":"Evi"},{"last_name":"Praetorius","full_name":"Praetorius, Florian M","first_name":"Florian M","id":"dfec9381-4341-11ee-8fd8-faa02bba7d62"},{"full_name":"de Oliveira Mann, Carina C.","first_name":"Carina C.","last_name":"de Oliveira Mann"},{"last_name":"Hopfner","full_name":"Hopfner, Karl-Peter","first_name":"Karl-Peter"},{"last_name":"Dietz","full_name":"Dietz, Hendrik","first_name":"Hendrik"}],"type":"journal_article","day":"01","title":"Impact of heterogeneity and lattice bond strength on DNA triangle crystal growth","citation":{"ama":"Stahl E, Praetorius FM, de Oliveira Mann CC, Hopfner K-P, Dietz H.
