Herein, FeCoNiMoW HEA nanoparticles are synthesized using a solution‐based low‐temperature approach. Such FeCoNiMoW nanoparticles show high entropy properties, subtle lattice distortions, and modulated electronic structure, leading to superior OER performance with an overpotential of 233 mV at 10 mA cm−2 and 276 mV at 100 mA cm−2. Density functional theory calculations reveal the electronic structures of the FeCoNiMoW active sites with an optimized d‐band center position that enables suitable adsorption of OOH* intermediates and reduces the Gibbs free energy barrier in the OER process. Aqueous zinc–air batteries (ZABs) based on this HEA demonstrate a high open circuit potential of 1.59 V, a peak power density of 116.9 mW cm−2, a specific capacity of 857 mAh gZn−1, and excellent stability for over 660 h of continuous charge–discharge cycles. Flexible and solid ZABs are also assembled and tested, displaying excellent charge–discharge performance at different bending angles.

However, sluggish ionic transport kinetics and the unstable electrode structure during ionic insertion/extraction hampers their deployment. Herein, we propose a new cathode material based on a layered metal chalcogenide (LMC), bismuth telluride (Bi2Te3), coated with polypyrrole (PPy). Taking advantage of the PPy coating, the Bi2Te3@PPy composite presents strong ionic absorption affinity, high oxidation resistance, and high structural stability. The ZIBs based on Bi2Te3@PPy cathodes exhibit high capacities and ultra‐long lifespans of over 5000 cycles. They also present outstanding stability even under bending. In addition, we analyze here the reaction mechanism using in situ X‐ray diffraction, X‐ray photoelectron spectroscopy, and computational tools and demonstrate that, in the aqueous system, Zn2+ is not inserted into the cathode as previously assumed. In contrast, proton charge storage dominates the process. Overall, this work not only shows the great potential of LMCs as ZIBs cathode materials and the advantages of PPy coating, but also clarifies the charge/discharge mechanism in rechargeable ZIBs based on LMCs."}],"quality_controlled":"1","publication_status":"accepted","publication_identifier":{"eissn":["1521-4095"],"issn":["0935-9648"]}},{"department":[{"_id":"MaIb"}],"month":"12","citation":{"mla":"Mollania, Hamid, et al. “Nanostructured Li₂S Cathodes for Silicon-Sulfur Batteries.” ACS Applied Materials and Interfaces, vol. 15, no. 50, American Chemical Society, 2023, pp. 58462–58475, doi:10.1021/acsami.3c14072.","apa":"Mollania, H., Zhang, C., Du, R., Qi, X., Li, J., Horta, S., … Cabot, A.

In this scenario, the implementation of lithium sulfide (Li2S) cathodes compatible with alternative anode materials such as silicon has the potential to alleviate the safety concerns associated with lithium metal. In this direction, here, we report a sulfur cathode based on Li2S nanocrystals grown on a catalytic host consisting of CoFeP nanoparticles supported on tubular carbon nitride. Nanosized Li2S is incorporated into the host by a scalable liquid infiltration–evaporation method. Theoretical calculations and experimental results demonstrate that the CoFeP–CN composite can boost the polysulfide adsorption/conversion reaction kinetics and strongly reduce the initial overpotential activation barrier by stretching the Li–S bonds of Li2S. Besides, the ultrasmall size of the Li2S particles in the Li2S–CoFeP–CN composite cathode facilitates the initial activation. Overall, the Li2S–CoFeP–CN electrodes exhibit a low activation barrier of 2.56 V, a high initial capacity of 991 mA h gLi2S–1, and outstanding cyclability with a small fading rate of 0.029% per cycle over 800 cycles. Moreover, Si/Li2S full cells are assembled using the nanostructured Li2S–CoFeP–CN cathode and a prelithiated anode based on graphite-supported silicon nanowires. These Si/Li2S cells demonstrate high initial discharge capacities above 900 mA h gLi2S–1 and good cyclability with a capacity fading rate of 0.28% per cycle over 150 cycles."}],"year":"2023","acknowledgement":"The authors acknowledge the support from the 2BoSS project of the ERA-MIN3 program with the Spanish grant number PCI2022-132985/AEI/10.13039/501100011033 and the French grant number ANR-22-MIN3-0003-01.

Cu3SbSe4 is a promising p-type TE material based on relatively earth abundant elements. However, the challenge lies in its poor electrical conductivity. Herein, an efficient and scalable solution-based approach is developed to synthesize high-quality Cu3SbSe4 nanocrystals doped with Pb at the Sb site. After ligand displacement and annealing treatments, the dried powders are consolidated into dense pellets, and their TE properties are investigated. Pb doping effectively increases the charge carrier concentration, resulting in a significant increase in electrical conductivity, while the Seebeck coefficients remain consistently high. The calculated band structure shows that Pb doping induces band convergence, thereby increasing the effective mass. Furthermore, the large ionic radius of Pb2+ results in the generation of additional point and plane defects and interphases, dramatically enhancing phonon scattering, which significantly decreases the lattice thermal conductivity at high temperatures. Overall, a maximum figure of merit (zTmax) ≈ 0.85 at 653 K is obtained in Cu3Sb0.97Pb0.03Se4. This represents a 1.6-fold increase compared to the undoped sample and exceeds most doped Cu3SbSe4-based materials produced by solid-state, demonstrating advantages of versatility and cost-effectiveness using a solution-based technology."}],"type":"journal_article","article_type":"original","date_created":"2024-01-07T23:00:51Z","date_updated":"2024-01-08T09:17:04Z","_id":"14734","publisher":"Wiley","oa_version":"None","title":"Band engineering through Pb-doping of nanocrystal building blocks to enhance thermoelectric performance in Cu3SbSe4","author":[{"last_name":"Wan","full_name":"Wan, Shanhong","first_name":"Shanhong"},{"first_name":"Shanshan","last_name":"Xiao","full_name":"Xiao, Shanshan"},{"full_name":"Li, Mingquan","last_name":"Li","first_name":"Mingquan"},{"full_name":"Wang, Xin","last_name":"Wang","first_name":"Xin"},{"first_name":"Khak Ho","full_name":"Lim, Khak Ho","last_name":"Lim"},{"full_name":"Hong, Min","last_name":"Hong","first_name":"Min"},{"full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","first_name":"Maria"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"},{"last_name":"Liu","full_name":"Liu, Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","first_name":"Yu","orcid":"0000-0001-7313-6740"}],"doi":"10.1002/smtd.202301377","scopus_import":"1","day":"28","article_processing_charge":"No","date_published":"2023-12-28T00:00:00Z","acknowledgement":"Y.L. acknowledges funding from the National Natural Science Foundation of China (NSFC) (Grants No. 22209034), the Innovation and Entrepreneurship Project of Overseas Returnees in Anhui Province (Grant No. 2022LCX002).

However, the relatively high material processing cost limits their real applications. Silver selenide (Ag2Se) is one of the very few n-type thermoelectric (TE) materials for room-temperature applications. Herein, we report a room temperature, fast, and aqueous-phase synthesis approach to produce Ag2Se, which can be extended to other metal chalcogenides. These materials reach TE figures of merit (zT) of up to 0.76 at 380 K. To improve these values, bismuth sulfide (Bi2S3) particles also prepared in an aqueous solution are incorporated into the Ag2Se matrix. In this way, a series of Ag2Se/Bi2S3 composites with Bi2S3 wt % of 0.5, 1.0, and 1.5 are prepared by solution blending and hot-press sintering. The presence of Bi2S3 significantly improves the Seebeck coefficient and power factor while at the same time decreasing the thermal conductivity with no apparent drop in electrical conductivity. Thus, a maximum zT value of 0.96 is achieved in the composites with 1.0 wt % Bi2S3 at 370 K. Furthermore, a high average zT value (zTave) of 0.93 in the 300–390 K range is demonstrated."}],"publication_status":"epub_ahead","publication_identifier":{"eissn":["2637-6113"]}},{"_id":"13235","date_updated":"2023-08-02T06:29:55Z","type":"journal_article","article_processing_charge":"No","doi":"10.1021/acsnano.3c03541","publisher":"American Chemical Society","quality_controlled":"1","page":"11923–11934","isi":1,"year":"2023","external_id":{"isi":["001008564800001"],"pmid":["37310395"]},"pmid":1,"acknowledgement":"Y.L. acknowledges funding from the National Natural Science Foundation of China (NSFC) (Grants No. 22209034), the Innovation and Entrepreneurship Project of Overseas Returnees in Anhui Province (Grant No. 2022LCX002).

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"}],"department":[{"_id":"MaIb"}],"month":"06","citation":{"ama":"Liu Y, Li M, Wan S, et al.

To this end, the combination of an electrolyte-gated field-effect transistor (EG-FET) with a fiber optic-coupled surface plasmon resonance (FO-SPR) probe serving as gate electrode has been investigated to deconvolute surface mass and charge density variations associated to surface reactions. However, applying an electrochemical potential on such gold-coated FO-SPR gate electrodes can induce gradual morphological changes of the thin gold film, leading to an irreversible blue-shift of the SPR wavelength and a substantial signal drift. We show that mild annealing leads to optical and electronic signal stabilization (20-fold lower signal drift than as-sputtered fiber optic gates) and improved overall analytical performance characteristics. The thermal treatment prevents morphological changes of the thin gold-film occurring during operation, hence providing reliable and stable data immediately upon gate voltage application. Thus, the readout output of both transducing principles, the optical FO-SPR and electronic EG-FET, stays constant throughout the whole sensing time-window and the long-term effect of thermal treatment is also improved, providing stable signals even after 1 year of storage. Annealing should therefore be considered a necessary modification for applying fiber optic gate electrodes in real-time multimodal investigations of surface reactions at the solid-liquid interface.","lang":"eng"}],"acknowledged_ssus":[{"_id":"EM-Fac"}],"volume":11,"article_type":"original","date_created":"2023-08-06T22:01:11Z","author":[{"last_name":"Hasler","full_name":"Hasler, Roger","first_name":"Roger"},{"first_name":"Marie Helene","last_name":"Steger-Polt","full_name":"Steger-Polt, Marie Helene"},{"full_name":"Reiner-Rozman, Ciril","last_name":"Reiner-Rozman","first_name":"Ciril"},{"full_name":"Fossati, Stefan","last_name":"Fossati","first_name":"Stefan"},{"orcid":"0000-0002-6962-8598","first_name":"Seungho","full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee"},{"first_name":"Patrik","full_name":"Aspermair, Patrik","last_name":"Aspermair"},{"first_name":"Christoph","last_name":"Kleber","full_name":"Kleber, Christoph"},{"full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","first_name":"Maria"},{"full_name":"Dostalek, Jakub","last_name":"Dostalek","first_name":"Jakub"},{"last_name":"Knoll","full_name":"Knoll, Wolfgang","first_name":"Wolfgang"}],"scopus_import":"1","day":"14","title":"Optical and electronic signal stabilization of plasmonic fiber optic gate electrodes: Towards improved real-time dual-mode biosensing","oa_version":"Published Version","citation":{"short":"R.

Herein, we detail a colloidal synthesis route for the incorporation of P on Pd2Sn nanoparticles. These nanoparticles are dispersed on carbon black and the obtained composite is used as electrocatalytic material for the FOR. The Pd2Sn0.8P-based electrodes present outstanding catalytic activities with record mass current densities up to 10.0 A mgPd-1, well above those of Pd1.6Sn/C reference electrode. These high current densities are further enhanced by increasing the temperature from 25 °C to 40 °C. The Pd2Sn0.8P electrode also allows for slowing down the rapid current decay that generally happens during operation and can be rapidly re-activated through potential cycling. The excellent catalytic performance obtained is rationalized using density functional theory (DFT) calculations.","lang":"eng"}],"intvolume":" 936","date_created":"2023-04-16T22:01:06Z","article_type":"original","volume":936,"title":"Phosphorous incorporation into palladium tin nanoparticles for the electrocatalytic formate oxidation reaction","oa_version":"None","day":"01","scopus_import":"1","author":[{"first_name":"Guillem","last_name":"Montaña-Mora","full_name":"Montaña-Mora, Guillem"},{"first_name":"Xueqiang","full_name":"Qi, Xueqiang","last_name":"Qi"},{"full_name":"Wang, Xiang","last_name":"Wang","first_name":"Xiang"},{"last_name":"Chacón-Borrero","full_name":"Chacón-Borrero, Jesus","first_name":"Jesus"},{"full_name":"Martinez-Alanis, Paulina R.","last_name":"Martinez-Alanis","first_name":"Paulina R."},{"first_name":"Xiaoting","full_name":"Yu, Xiaoting","last_name":"Yu"},{"full_name":"Li, Junshan","last_name":"Li","first_name":"Junshan"},{"last_name":"Xue","full_name":"Xue, Qian","first_name":"Qian"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}]},{"quality_controlled":"1","page":"287-298","type":"journal_article","_id":"12832","date_updated":"2023-08-01T14:08:02Z","publisher":"Elsevier","article_processing_charge":"No","doi":"10.1016/j.ensm.2023.03.022","acknowledgement":"The authors thank the support from the project COMBENERGY, PID2019-105490RB-C32, from the Spanish Ministerio de Ciencia e Innovación.

Such catalysts must contain multiple adsorption/reaction sites to cope with the high demands of reversible oxygen electrodes. Herein, we propose a high entropy alloy (HEA) based on relatively abundant elements as a bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays superior OER performance with an overpotential of 265 mV at a current density of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard commercial catalyst based on RuO2. This high performance is partially explained by the presence of twinned defects, the incidence of large lattice distortions, and the electronic synergy between the different components, being Cr key to decreasing the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays superior ORR performance with a half-potential of 0.78 V and an onset potential of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi HEA as air cathode and a zinc foil as the anode. The assembled cells provide an open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8 mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2."}],"date_created":"2023-04-16T22:01:07Z","article_type":"original","volume":58,"oa_version":"None","title":"A CrMnFeCoNi high entropy alloy boosting oxygen evolution/reduction reactions and zinc-air battery performance","day":"01","scopus_import":"1","author":[{"first_name":"Ren","last_name":"He","full_name":"He, Ren"},{"first_name":"Linlin","last_name":"Yang","full_name":"Yang, Linlin"},{"first_name":"Yu","last_name":"Zhang","full_name":"Zhang, Yu"},{"first_name":"Xiang","last_name":"Wang","full_name":"Wang, Xiang"},{"orcid":"0000-0002-6962-8598","first_name":"Seungho","last_name":"Lee","full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425"},{"first_name":"Ting","last_name":"Zhang","full_name":"Zhang, Ting"},{"last_name":"Li","full_name":"Li, Lingxiao","first_name":"Lingxiao"},{"last_name":"Liang","full_name":"Liang, Zhifu","first_name":"Zhifu"},{"full_name":"Chen, Jingwei","last_name":"Chen","first_name":"Jingwei"},{"first_name":"Junshan","last_name":"Li","full_name":"Li, Junshan"},{"first_name":"Ahmad","full_name":"Ostovari Moghaddam, Ahmad","last_name":"Ostovari Moghaddam"},{"full_name":"Llorca, Jordi","last_name":"Llorca","first_name":"Jordi"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"last_name":"Xu","full_name":"Xu, Ying","first_name":"Ying"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"apa":"He, R., Yang, L., Zhang, Y., Wang, X., Lee, S., Zhang, T., … Cabot, A.

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"}],"intvolume":" 17","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"publication_status":"published","month":"05","department":[{"_id":"MaIb"}],"language":[{"iso":"eng"}],"issue":"9","citation":{"chicago":"Xing, Congcong, Yu Zhang, Ke Xiao, Xu Han, Yu Liu, Bingfei Nan, Maria Garcia Ramon, et al. “Thermoelectric Performance of Surface-Engineered Cu1.5–XTe–Cu2Se Nanocomposites.” ACS Nano.

The dual-mode sensor allows for discrimination of mass and charge contributions for binding assays on the same sensor surface. Furthermore, we optimize the sensor geometry by investigating the influence of the fiber area to transistor channel area ratio and distance. We show that larger fiber optic tip diameters are favorable for electronic and optical signals and demonstrate the reversibility of plasmon resonance wavelength shifts after electric field application. As a proof of principle, a layer-by-layer assembly of polyelectrolytes is performed to benchmark the system against multivariable sensing platforms with planar surface plasmon resonance configurations. Furthermore, the biosensing performance is assessed using a thrombin binding assay with surface-immobilized aptamers as receptors, allowing for the detection of medically relevant thrombin concentrations.","lang":"eng"}],"has_accepted_license":"1","file_date_updated":"2022-03-07T08:15:01Z","publication_identifier":{"eissn":["23793694"]},"publication_status":"published","oa_version":"Published Version","title":"Field-effect transistor with a plasmonic fiber optic gate electrode as a multivariable biosensor device","day":"08","scopus_import":"1","author":[{"first_name":"Roger","full_name":"Hasler, Roger","last_name":"Hasler"},{"last_name":"Reiner-Rozman","full_name":"Reiner-Rozman, Ciril","first_name":"Ciril"},{"last_name":"Fossati","full_name":"Fossati, Stefan","first_name":"Stefan"},{"first_name":"Patrik","last_name":"Aspermair","full_name":"Aspermair, Patrik"},{"full_name":"Dostalek, Jakub","last_name":"Dostalek","first_name":"Jakub"},{"full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee","orcid":"0000-0002-6962-8598","first_name":"Seungho"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez"},{"first_name":"Johannes","last_name":"Bintinger","full_name":"Bintinger, Johannes"},{"full_name":"Knoll, Wolfgang","last_name":"Knoll","first_name":"Wolfgang"}],"date_created":"2022-03-06T23:01:54Z","article_type":"original","volume":7,"language":[{"iso":"eng"}],"oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Hasler, Roger, et al. “Field-Effect Transistor with a Plasmonic Fiber Optic Gate Electrode as a Multivariable Biosensor Device.” ACS Sensors, vol. 7, no. 2, American Chemical Society, 2022, pp. 504–12, doi:10.1021/acssensors.1c02313.","apa":"Hasler, R., Reiner-Rozman, C., Fossati, S., Aspermair, P., Dostalek, J., Lee, S., … Knoll, W.

Here, we first obtain phase-pure, colloidally stable nanocubes. Second, we elucidate the pathway by which copper(II) nitrate and oleylamine form Cu3N. We find that oleylamine is both a reductant and a nitrogen source. Oleylamine is oxidized by nitrate to a primary aldimine, which reacts further with excess oleylamine to a secondary aldimine, eliminating ammonia. Ammonia reacts with CuI to form Cu3N. Third, we investigated the surface chemistry and find a mixed ligand shell of aliphatic amines and carboxylates (formed in situ). While the carboxylates appear tightly bound, the amines are easily desorbed from the surface. Finally, we show that doping with palladium decreases the band gap and the material becomes semi-metallic. These results bring insight into the chemistry of metal nitrides and might help the development of other metal nitride nanocrystals.","lang":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":" 61","publication_identifier":{"issn":["1433-7851"],"eissn":["1521-3773"]},"publication_status":"published","file_date_updated":"2022-07-29T09:29:20Z","author":[{"last_name":"Parvizian","full_name":"Parvizian, Mahsa","first_name":"Mahsa"},{"first_name":"Alejandra","last_name":"Duràn Balsa","full_name":"Duràn Balsa, Alejandra"},{"first_name":"Rohan","last_name":"Pokratath","full_name":"Pokratath, Rohan"},{"first_name":"Curran","last_name":"Kalha","full_name":"Kalha, Curran"},{"full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee","first_name":"Seungho","orcid":"0000-0002-6962-8598"},{"full_name":"Van Den Eynden, Dietger","last_name":"Van Den Eynden","first_name":"Dietger"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez"},{"first_name":"Anna","full_name":"Regoutz, Anna","last_name":"Regoutz"},{"first_name":"Jonathan","last_name":"De Roo","full_name":"De Roo, Jonathan"}],"day":"01","scopus_import":"1","title":"The chemistry of Cu₃N and Cu₃PdN nanocrystals","oa_version":"Published Version","volume":61,"article_type":"original","date_created":"2022-06-19T22:01:58Z","oa":1,"language":[{"iso":"eng"}],"issue":"31","citation":{"short":"M.

One possibility is employing surfactant-free solution synthesis to produce nanopowders. We propose the strategy of functionalizing “naked” particles’ surface by inorganic molecules to control the nanostructure and, consequently, thermoelectric performance. In particular, we use bismuth thiolates to functionalize surfactant-free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates decomposition renders SnTe-Bi2S3 nanocomposites with synergistic functions: 1) carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity reduction by small grain domains, grain boundaries and nanostructuration. Overall, the SnTe-Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average z T of ≈0.6 at 300–873 K, which is among the highest reported for solution-processed SnTe.","lang":"eng"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","short":"CC BY (4.0)"},"intvolume":" 61","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"department":[{"_id":"MaIb"},{"_id":"EM-Fac"}],"file":[{"file_id":"12476","date_updated":"2023-02-02T08:01:00Z","creator":"dernst","file_size":4072650,"date_created":"2023-02-02T08:01:00Z","checksum":"ad601f2b9e26e46ab4785162be58b5ed","relation":"main_file","access_level":"open_access","content_type":"application/pdf","success":1,"file_name":"2022_AngewandteChemieInternat_Chang.pdf"}],"article_number":"e202207002","month":"08","issue":"35","citation":{"ista":"Chang C, Liu Y, Lee S, Spadaro M, Koskela KM, Kleinhanns T, Costanzo T, Arbiol J, Brutchey RL, Ibáñez M. 2022.

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.","lang":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"file_date_updated":"2022-03-02T16:17:29Z","author":[{"last_name":"Liu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","full_name":"Liu, Yu","first_name":"Yu","orcid":"0000-0001-7313-6740"},{"first_name":"Mariano","id":"45D7531A-F248-11E8-B48F-1D18A9856A87","full_name":"Calcabrini, Mariano","last_name":"Calcabrini"},{"full_name":"Yu, Yuan","last_name":"Yu","first_name":"Yuan"},{"full_name":"Lee, Seungho","id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee","orcid":"0000-0002-6962-8598","first_name":"Seungho"},{"id":"9E331C2E-9F27-11E9-AE48-5033E6697425","full_name":"Chang, Cheng","last_name":"Chang","orcid":"0000-0002-9515-4277","first_name":"Cheng"},{"last_name":"David","full_name":"David, Jérémy","first_name":"Jérémy"},{"first_name":"Tanmoy","last_name":"Ghosh","full_name":"Ghosh, Tanmoy","id":"a5fc9bc3-feff-11ea-93fe-e8015a3c7e9d"},{"full_name":"Spadaro, Maria Chiara","last_name":"Spadaro","first_name":"Maria Chiara"},{"first_name":"Chenyang","full_name":"Xie, Chenyang","last_name":"Xie"},{"first_name":"Oana","full_name":"Cojocaru-Mirédin, Oana","last_name":"Cojocaru-Mirédin"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"first_name":"Maria","orcid":"0000-0001-5013-2843","id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","last_name":"Ibáñez"}],"day":"25","scopus_import":"1","title":"Defect engineering in solution-processed polycrystalline SnSe leads to high thermoelectric performance","oa_version":"Published Version","volume":16,"article_type":"original","date_created":"2021-09-24T07:55:12Z","project":[{"_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships"},{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385","name":"International IST Doctoral Program","call_identifier":"H2020"},{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"},{"_id":"9B8804FC-BA93-11EA-9121-9846C619BF3A","name":"Bottom-up Engineering for Thermoelectric Applications","grant_number":"M02889"}],"publication":"ACS Nano","status":"public","pmid":1,"ec_funded":1,"date_published":"2022-01-25T00:00:00Z","acknowledgement":"This work was financially supported by IST Austria and the Werner Siemens Foundation.

Subsequently, nanoparticles are annealed in a reducing atmosphere to remove surface oxide, and consolidated into dense polycrystalline materials by means of spark plasma sintering. By characterizing the transport properties of the sintered material, we observe the annealing step and the incorporation of Cu to play a key role in promoting the thermoelectric performance of PbS. The presence of Cu allows improving the electrical conductivity by increasing the charge carrier concentration and simultaneously maintaining a large charge carrier mobility, which overall translates into record power factors at ambient temperature, 2.3 mWm-1K−2. Simultaneously, the lattice thermal conductivity decreases with the introduction of Cu, leading to a record high ZT = 0.37 at room temperature and ZT = 1.22 at 773 K.
