Herein, we report the reaction precursor-mediated formation of stable PbTe supercrystals. Rationalizing the formation of these assemblies through small-angle x-ray scattering (SAXS) measurements, we unveil their formation mechanism. Our findings reveal that the supercrystal formation occurs in the presence of an excess of lead oleates in the crude solution. It should be noted that the formed supercrystals can be stabilized under specific conditions determined by the lead oleate cluster concentration, content of trioctylphosphine telluride (TOP-Te), NC size and the need of an annealing step at mild conditions. Furthermore, this approach allows for the continuous growth of a secondary phase within the supercrystal; for example in the case of PbTe supercrystals, a PbS shell can be grown on each PbTe NC constituent, resulting in core-shell PbTe-PbS supercrystals. Our work elucidates that reaction precursors play an important role in in situ SC formation and stabilization, implying the possibility of applying this knowledge to other NC reactions."}],"year":"2025","date_updated":"2026-02-19T09:25:57Z","month":"03","_id":"20055","day":"15","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NMR"},{"_id":"LifeSc"}],"publication":"Proceedings of the MATSUS Spring 2025 Conference","quality_controlled":"1","title":"Reaction precursor-mediated formation of stable supercrystals in colloidal nanocrystal synthesis: PbTe case","language":[{"iso":"eng"}],"author":[{"first_name":"Seungho","full_name":"Lee, Seungho","orcid":"0000-0002-6962-8598","last_name":"Lee","id":"BB243B88-D767-11E9-B658-BC13E6697425"},{"first_name":"Daniel","full_name":"Balazs, Daniel","last_name":"Balazs","orcid":"0000-0001-7597-043X","id":"302BADF6-85FC-11EA-9E3B-B9493DDC885E"},{"last_name":"Horta","full_name":"Horta, Sharona","first_name":"Sharona","id":"03a7e858-01b1-11ec-8b71-99ae6c4a05bc"},{"full_name":"Rayaroth Puthiyaveettil, Aiswarya","first_name":"Aiswarya","last_name":"Rayaroth Puthiyaveettil","id":"8aceb01b-8972-11ed-ae7b-d5fe53775add"},{"last_name":"Ibáñez","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"}],"type":"conference","citation":{"chicago":"Lee, Seungho, Daniel Balazs, Sharona Horta, Aiswarya Rayaroth Puthiyaveettil, and Maria Ibáñez. “Reaction Precursor-Mediated Formation of Stable Supercrystals in Colloidal Nanocrystal Synthesis: PbTe Case.” In <i>Proceedings of the MATSUS Spring 2025 Conference</i>.

In this study, FeCoNiMoW HEAs are synthesized into either amorphous nanosheets (HEANS) or crystalline nanoparticles (HEANP), which are then used to catalyze the lithium–sulfur (Li–S) reaction of Li–S batteries (LSBs). Evaluations in symmetric cells, coin cells, and pouch cells reveal that HEANS significantly enhance LSB performance, achieving initial discharge capacities up to 1632 mAh g−1. The batteries also exhibit excellent cycling stability over 1000 cycles at 3Cand maintain high-rate performance up to 10C with a capacity of 614 mAh g−1. Comprehensive in situ analyses and density functional theory calculations demonstrate that amorphous HEANS provide more active sites, better ionic conductivity and stronger chemical interactions with lithium polysulfides (LiPS). These properties effectively suppress the shuttle effect, promote the complete S8 → Li2S conversion by reducing the impedance of the solid-electrolyte interphase, and accelerate the Li2S4 → Li2S2 step by lowering the nucleation energy barrier. Overall, this study highlights the superior catalytic properties of amorphous 2D HEAs in LSBs and offers new insights into the mechanisms of LiPS conversion.","lang":"eng"}],"month":"08","isi":1,"date_updated":"2025-09-30T14:20:56Z","publisher":"Wiley","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/adfm.202513859"}],"date_published":"2025-08-06T00:00:00Z","acknowledged_ssus":[{"_id":"EM-Fac"}],"publication":"Advanced Functional Materials","day":"06","_id":"20191","acknowledgement":"The authors acknowledge support from the 2BoSS project of the ERA-MIN3 program with the Spanish grant number PCI2022-132985/AEI/10.13039/50110001103, and funding from Generalitat de Catalunya 2021SGR01581 and European Union NextGenerationEU/PRTR.

Although observing this effect is still practically unachievable, its analogue generalizations have been shown to be more readily attainable. This paper demonstrates that a gapped Dirac semiconductor, methylammonium lead-bromide perovskite (MAPbBr3), exhibits analogue dynamic Schwinger effect. Tunneling ionization under deep subgap mid-infrared irradiation leads to intense photoluminescence in the visible range, in full agreement with quasi-adiabatic theory. In addition to revealing a gapped extended system suitable for studying the analogue Schwinger effect, this observation holds great potential for nonperturbative field sensing, i.e., sensing electric fields through nonperturbative light-matter interactions. First, this paper illustrates this by measuring the local deviation from the nominally cubic phase of a perovskite single crystal, which can be interpreted in terms of frozen-in fields. Next, it is shown that analogue dynamic Schwinger effect can be used for nonperturbative amplification of nonparametric upconversion process in perovskites driven simultaneously by multiple optical fields. This discovery demonstrates the potential for material response beyond perturbation theory in the tunneling regime, offering extremely sensitive light detection and amplification across an ultrabroad spectral range not accessible by conventional devices."}],"oa_version":"Published Version","file":[{"file_size":6609950,"success":1,"date_updated":"2025-10-20T11:02:21Z","content_type":"application/pdf","file_name":"2025_ACSPhotonics_Lorenc.pdf","checksum":"d42476279287a9a2f8aeafaef032f4a7","access_level":"open_access","creator":"dernst","date_created":"2025-10-20T11:02:21Z","relation":"main_file","file_id":"20502"}],"article_processing_charge":"Yes (via OA deal)","project":[{"name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery","_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A"}],"publication_status":"published","OA_place":"publisher","language":[{"iso":"eng"}],"author":[{"last_name":"Lorenc","full_name":"Lorenc, Dusan","first_name":"Dusan","id":"40D8A3E6-F248-11E8-B48F-1D18A9856A87"},{"id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev","orcid":"0000-0003-0393-5525","full_name":"Volosniev, Artem","first_name":"Artem"},{"last_name":"Zhumekenov","full_name":"Zhumekenov, Ayan A.","first_name":"Ayan A."},{"first_name":"Seungho","full_name":"Lee, Seungho","orcid":"0000-0002-6962-8598","last_name":"Lee","id":"BB243B88-D767-11E9-B658-BC13E6697425"},{"orcid":"0000-0001-5013-2843","last_name":"Ibáñez","first_name":"Maria","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Osman M.","full_name":"Bakr, Osman M.","last_name":"Bakr"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","full_name":"Lemeshko, Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802"},{"last_name":"Alpichshev","orcid":"0000-0002-7183-5203","full_name":"Alpichshev, Zhanybek","first_name":"Zhanybek","id":"45E67A2A-F248-11E8-B48F-1D18A9856A87"}],"external_id":{"isi":["001547359300001"],"arxiv":["2406.05032"]},"status":"public","intvolume":"        12","page":"5220-5230","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"quality_controlled":"1","title":"Observation of analogue dynamic Schwinger effect and non-perturbative light sensing in lead halide perovskites","OA_type":"hybrid","has_accepted_license":"1","volume":12,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","PlanS_conform":"1","date_created":"2025-09-28T22:01:26Z","ddc":["540","530"],"corr_author":"1","article_type":"original"},{"publication_identifier":{"issn":["2663-337X"]},"degree_awarded":"PhD","doi":"10.15479/AT-ISTA-20415","citation":{"ieee":"S.

In this study, we present a low-temperature solution-based approach to produce SnSe-PbSe nanocomposites with outstanding TE performance. Our method involves combining surfactant-free SnSe particles with oleate-capped PbSe nanocrystals in specific ratios, followed by thermal annealing and consolidation using spark plasma sintering. These nanocomposites are characterized by distinct compositional and structural properties that significantly impact their transport properties. In particular, the addition of oleate-capped PbSe nanocrystals results in: i) a reduction in the electrostatically adsorbed Na at the surface of the SnSe particles; ii) a reduction of Sn vacancies due to alloying with Pb; iii) an increase in grain boundary density; and iv) the formation of PbSnSe secondary phases. Notably, the SnSe-2.5 %PbSe nanocomposites demonstrate a 30 % decrease in thermal conductivity compared to that of the SnSe matrix. This reduction contributes to a maximum figure of merit (zT) of 1.75 at 788 K with a high average zT value of ca. 1.2 in the medium temperature range of 573–773 K. These values represent one of the highest reported in polycrystalline SnSe materials, showcasing the potential of our fabricated SnSe-PbSe nanocomposites for cost-effective TE applications."}],"year":"2024","isi":1,"month":"06","date_updated":"2026-04-07T11:52:31Z","publisher":"Elsevier","date_published":"2024-06-15T00:00:00Z","OA_place":"publisher","publication_status":"published","project":[{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"}],"article_processing_charge":"Yes (via OA deal)","oa_version":"Published Version","file":[{"content_type":"application/pdf","file_name":"2024_ChemEngineeringJour_Liu.pdf","checksum":"6609232a208b9a89d055a270ef0af1fe","file_size":12233704,"date_updated":"2025-01-09T09:24:29Z","success":1,"file_id":"18800","access_level":"open_access","creator":"dernst","date_created":"2025-01-09T09:24:29Z","relation":"main_file"}],"publication_identifier":{"issn":["1385-8947"]},"acknowledgement":"The Scientific Service Units (SSU) of ISTA supported this research through resources provided by the Electron Microscopy Facility (EMF), NMR Facility, and the Lab Support Facility (LSF).

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"}],"date_published":"2023-07-14T00:00:00Z","publisher":"Frontiers","publication":"Frontiers in Physics","acknowledged_ssus":[{"_id":"EM-Fac"}],"file_date_updated":"2023-08-07T07:48:11Z","day":"14","_id":"13968","doi":"10.3389/fphy.2023.1202132","publication_identifier":{"eissn":["2296-424X"]},"acknowledgement":"This project has received funding from the European Union’s Horizon 2020 Research and Innovation Programme under the Marie Skłodowska-Curie grant agreement No. 813863–BORGES.

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."}],"year":"2023","month":"04","isi":1,"date_updated":"2025-06-25T06:12:51Z","page":"287-298","title":"A CrMnFeCoNi high entropy alloy boosting oxygen evolution/reduction reactions and zinc-air battery performance","quality_controlled":"1","author":[{"last_name":"He","full_name":"He, Ren","first_name":"Ren"},{"last_name":"Yang","first_name":"Linlin","full_name":"Yang, Linlin"},{"last_name":"Zhang","first_name":"Yu","full_name":"Zhang, Yu"},{"full_name":"Wang, Xiang","first_name":"Xiang","last_name":"Wang"},{"id":"BB243B88-D767-11E9-B658-BC13E6697425","last_name":"Lee","orcid":"0000-0002-6962-8598","first_name":"Seungho","full_name":"Lee, Seungho"},{"last_name":"Zhang","first_name":"Ting","full_name":"Zhang, Ting"},{"first_name":"Lingxiao","full_name":"Li, Lingxiao","last_name":"Li"},{"full_name":"Liang, Zhifu","first_name":"Zhifu","last_name":"Liang"},{"full_name":"Chen, Jingwei","first_name":"Jingwei","last_name":"Chen"},{"full_name":"Li, Junshan","first_name":"Junshan","last_name":"Li"},{"first_name":"Ahmad","full_name":"Ostovari Moghaddam, Ahmad","last_name":"Ostovari Moghaddam"},{"first_name":"Jordi","full_name":"Llorca, Jordi","last_name":"Llorca"},{"orcid":"0000-0001-5013-2843","last_name":"Ibáñez","first_name":"Maria","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Arbiol","full_name":"Arbiol, Jordi","first_name":"Jordi"},{"last_name":"Xu","full_name":"Xu, Ying","first_name":"Ying"},{"first_name":"Andreu","full_name":"Cabot, Andreu","last_name":"Cabot"}],"external_id":{"isi":["000967601700001"]},"language":[{"iso":"eng"}],"intvolume":"        58","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_type":"original","date_created":"2023-04-16T22:01:07Z","OA_type":"green","volume":58},{"file":[{"relation":"main_file","date_created":"2022-07-29T09:29:20Z","creator":"dernst","access_level":"open_access","file_id":"11696","date_updated":"2022-07-29T09:29:20Z","success":1,"file_size":1303202,"checksum":"2a3ee0bb59e044b808ebe85cd94ac899","file_name":"2022_AngewandteChemieInternat_Parvizian.pdf","content_type":"application/pdf"}],"oa_version":"Published Version","article_processing_charge":"No","publication_status":"published","publisher":"Wiley","date_published":"2022-08-01T00:00:00Z","isi":1,"month":"08","date_updated":"2023-08-03T07:19:12Z","scopus_import":"1","abstract":[{"lang":"eng","text":"The precursor conversion chemistry and surface chemistry of Cu3N and Cu3PdN nanocrystals are unknown or contested. 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."}],"year":"2022","day":"01","_id":"11451","publication":"Angewandte Chemie - International Edition","issue":"31","file_date_updated":"2022-07-29T09:29:20Z","department":[{"_id":"MaIb"}],"citation":{"mla":"Parvizian, Mahsa, et al. “The Chemistry of Cu₃N and Cu₃PdN Nanocrystals.” <i>Angewandte Chemie - International Edition</i>, vol. 61, no. 31, e202207013, Wiley, 2022, doi:<a href=\"https://doi.org/10.1002/anie.202207013\">10.1002/anie.202207013</a>.","ama":"Parvizian M, Duràn Balsa A, Pokratath R, et al.

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."}],"year":"2022","date_updated":"2025-04-14T07:44:07Z","month":"08","isi":1,"oa_version":"Published Version","file":[{"date_updated":"2023-02-02T08:01:00Z","success":1,"file_size":4072650,"checksum":"ad601f2b9e26e46ab4785162be58b5ed","file_name":"2022_AngewandteChemieInternat_Chang.pdf","content_type":"application/pdf","relation":"main_file","date_created":"2023-02-02T08:01:00Z","creator":"dernst","access_level":"open_access","file_id":"12476"}],"publication_status":"published","article_processing_charge":"Yes (via OA deal)","project":[{"grant_number":"M02889","_id":"9B8804FC-BA93-11EA-9121-9846C619BF3A","name":"Bottom-up Engineering for Thermoelectric Applications"},{"_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411"}],"language":[{"iso":"eng"}],"external_id":{"isi":["000828274200001"],"pmid":["38505739"]},"author":[{"id":"9E331C2E-9F27-11E9-AE48-5033E6697425","last_name":"Chang","orcid":"0000-0002-9515-4277","full_name":"Chang, Cheng","first_name":"Cheng"},{"orcid":"0000-0001-7313-6740","last_name":"Liu","full_name":"Liu, Yu","first_name":"Yu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87"},{"id":"BB243B88-D767-11E9-B658-BC13E6697425","orcid":"0000-0002-6962-8598","last_name":"Lee","full_name":"Lee, Seungho","first_name":"Seungho"},{"first_name":"Maria","full_name":"Spadaro, Maria","last_name":"Spadaro"},{"full_name":"Koskela, Kristopher M.","first_name":"Kristopher M.","last_name":"Koskela"},{"id":"8BD9DE16-AB3C-11E9-9C8C-2A03E6697425","last_name":"Kleinhanns","full_name":"Kleinhanns, Tobias","first_name":"Tobias"},{"full_name":"Costanzo, Tommaso","first_name":"Tommaso","last_name":"Costanzo","orcid":"0000-0001-9732-3815","id":"D93824F4-D9BA-11E9-BB12-F207E6697425"},{"full_name":"Arbiol, Jordi","first_name":"Jordi","last_name":"Arbiol"},{"first_name":"Richard L.","full_name":"Brutchey, Richard L.","last_name":"Brutchey"},{"first_name":"Maria","full_name":"Ibáñez, Maria","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","id":"43C61214-F248-11E8-B48F-1D18A9856A87"}],"intvolume":"        61","status":"public","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"quality_controlled":"1","title":"Surface functionalization of surfactant-free particles: A strategy to tailor the properties of nanocomposites for enhanced thermoelectric performance","has_accepted_license":"1","volume":61,"ec_funded":1,"article_number":"e202207002","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","pmid":1,"corr_author":"1","article_type":"original","date_created":"2022-07-31T22:01:48Z","ddc":["540"]},{"volume":7,"related_material":{"record":[{"id":"10833","relation":"research_data","status":"public"}]},"has_accepted_license":"1","article_type":"original","date_created":"2022-03-06T23:01:54Z","ddc":["540"],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","pmid":1,"intvolume":"         7","status":"public","language":[{"iso":"eng"}],"author":[{"first_name":"Roger","full_name":"Hasler, Roger","last_name":"Hasler"},{"last_name":"Reiner-Rozman","full_name":"Reiner-Rozman, Ciril","first_name":"Ciril"},{"first_name":"Stefan","full_name":"Fossati, Stefan","last_name":"Fossati"},{"full_name":"Aspermair, Patrik","first_name":"Patrik","last_name":"Aspermair"},{"full_name":"Dostalek, Jakub","first_name":"Jakub","last_name":"Dostalek"},{"first_name":"Seungho","full_name":"Lee, Seungho","last_name":"Lee","orcid":"0000-0002-6962-8598","id":"BB243B88-D767-11E9-B658-BC13E6697425"},{"last_name":"Ibáñez","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","first_name":"Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Bintinger","first_name":"Johannes","full_name":"Bintinger, Johannes"},{"last_name":"Knoll","first_name":"Wolfgang","full_name":"Knoll, Wolfgang"}],"external_id":{"isi":["000765113000016"],"pmid":["35134289"]},"quality_controlled":"1","title":"Field-effect transistor with a plasmonic fiber optic gate electrode as a multivariable biosensor device","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"page":"504-512","scopus_import":"1","abstract":[{"text":"A novel multivariable system, combining a transistor with fiber optic-based surface plasmon resonance spectroscopy with the gate electrode simultaneously acting as the fiber optic sensor surface, is reported.

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.

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."}],"file":[{"content_type":"application/pdf","file_name":"2022_ACSNano_Liu.pdf","checksum":"74f9c1aa5f95c0b992a4328e8e0247b4","file_size":9050764,"date_updated":"2022-03-02T16:17:29Z","success":1,"file_id":"10808","access_level":"open_access","creator":"cchlebak","date_created":"2022-03-02T16:17:29Z","relation":"main_file"}],"oa_version":"Published Version","article_processing_charge":"Yes (via OA deal)","project":[{"grant_number":"754411","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","grant_number":"665385","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program"},{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"},{"grant_number":"M02889","_id":"9B8804FC-BA93-11EA-9121-9846C619BF3A","name":"Bottom-up Engineering for Thermoelectric Applications"}],"publication_status":"published"},{"has_accepted_license":"1","ec_funded":1,"related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"20415"},{"id":"12885","status":"public","relation":"dissertation_contains"}]},"volume":34,"pmid":1,"keyword":["Materials Chemistry","General Chemical Engineering","General Chemistry"],"user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","ddc":["540"],"date_created":"2023-01-16T09:51:26Z","article_type":"original","corr_author":"1","external_id":{"pmid":["36248227"],"isi":["000917837600001"]},"author":[{"id":"bd3fceba-dc74-11ea-a0a7-c17f71817366","full_name":"Fiedler, Christine","first_name":"Christine","last_name":"Fiedler"},{"full_name":"Kleinhanns, Tobias","first_name":"Tobias","last_name":"Kleinhanns","orcid":"0000-0003-1537-7436","id":"8BD9DE16-AB3C-11E9-9C8C-2A03E6697425"},{"first_name":"Maria","full_name":"Garcia, Maria","last_name":"Garcia","id":"6e5c50b8-97dc-11ed-be98-b0a74c84cae0"},{"id":"BB243B88-D767-11E9-B658-BC13E6697425","orcid":"0000-0002-6962-8598","last_name":"Lee","first_name":"Seungho","full_name":"Lee, Seungho"},{"first_name":"Mariano","full_name":"Calcabrini, Mariano","last_name":"Calcabrini","orcid":"0000-0003-4566-5877","id":"45D7531A-F248-11E8-B48F-1D18A9856A87"},{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","last_name":"Ibáñez","orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","first_name":"Maria"}],"language":[{"iso":"eng"}],"status":"public","intvolume":"        34","page":"8471-8489","tmp":{"short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"title":"Solution-processed inorganic thermoelectric materials: Opportunities and challenges ∇","quality_controlled":"1","publisher":"American Chemical Society","date_published":"2022-09-20T00:00:00Z","month":"09","isi":1,"date_updated":"2026-04-07T13:26:13Z","scopus_import":"1","abstract":[{"text":"Thermoelectric technology requires synthesizing complex materials where not only the crystal structure but also other structural features such as defects, grain size and orientation, and interfaces must be controlled. To date, conventional solid-state techniques are unable to provide this level of control. Herein, we present a synthetic approach in which dense inorganic thermoelectric materials are produced by the consolidation of well-defined nanoparticle powders. The idea is that controlling the characteristics of the powder allows the chemical transformations that take place during consolidation to be guided, ultimately yielding inorganic solids with targeted features. Different from conventional methods, syntheses in solution can produce particles with unprecedented control over their size, shape, crystal structure, composition, and surface chemistry. However, to date, most works have focused only on the low-cost benefits of this strategy. In this perspective, we first cover the opportunities that solution processing of the powder offers, emphasizing the potential structural features that can be controlled by precisely engineering the inorganic core of the particle, the surface, and the organization of the particles before consolidation. We then discuss the challenges of this synthetic approach and more practical matters related to solution processing. Finally, we suggest some good practices for adequate knowledge transfer and improving reproducibility among different laboratories.","lang":"eng"}],"year":"2022","file":[{"creator":"dernst","access_level":"open_access","relation":"main_file","date_created":"2023-01-30T07:35:09Z","file_id":"12434","file_size":10923495,"date_updated":"2023-01-30T07:35:09Z","success":1,"content_type":"application/pdf","checksum":"f7143e44ab510519d1949099c3558532","file_name":"2022_ChemistryMaterials_Fiedler.pdf"}],"oa_version":"Published Version","project":[{"_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program","grant_number":"665385","call_identifier":"H2020"}],"article_processing_charge":"Yes (via OA deal)","publication_status":"published","type":"journal_article","citation":{"ieee":"C.

Towards solving these current challenges, in the present work, we detail a low temperature solution-based approach to produce Bi2Te3-Cu2-xTe nanocomposites with improved thermoelectric performance. Our approach consists in combining proper ratios of colloidal nanoparticles and to consolidate the resulting mixture into nanocomposites using a hot press. The transport properties of the nanocomposites are characterized and compared with those of pure Bi2Te3 nanomaterials obtained following the same procedure. In contrast with most previous works, the presence of Cu2-xTe nanodomains does not result in a significant reduction of the lattice thermal conductivity of the reference Bi2Te3 nanomaterial, which is already very low. However, the introduction of Cu2-xTe yields a nearly threefold increase of the power factor associated to a simultaneous increase of the Seebeck coefficient and electrical conductivity at temperatures above 400 K. Taking into account the band alignment of the two materials, we rationalize this increase by considering that Cu2-xTe nanostructures, with a relatively low electron affinity, are able to inject electrons into Bi2Te3, enhancing in this way its electrical conductivity. The simultaneous increase of the Seebeck coefficient is related to the energy filtering of charge carriers at energy barriers within Bi2Te3 domains associated with the accumulation of electrons in regions nearby a Cu2-xTe/Bi2Te3 heterojunction. Overall, with the incorporation of a proper amount of Cu2-xTe nanoparticles, we demonstrate a 250% improvement of the thermoelectric figure of merit of Bi2Te3."}],"day":"15","_id":"9304","publication":"Chemical Engineering Journal","issue":"8","citation":{"short":"Y.

However, solution synthesis generally involves the presence of additional molecules or ions belonging to the precursors or added to enable solubility and/or regulate nucleation and growth. These molecules or ions can end up in the particles as surface adsorbates and interfere in the material properties. This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically adsorbed in SnSe particles synthesized in water and play a crucial role not only in directing the material nano/microstructure but also in determining the transport properties of the consolidated material. In dense pellets prepared by sintering SnSe particles, Na remains within the crystal lattice as dopant, in dislocations, precipitates, and forming grain boundary complexions. These results highlight the importance of considering all the possible unintentional impurities to establish proper structure-property relationships and control material properties in solution-processed thermoelectric materials.","lang":"eng"}],"file":[{"date_created":"2022-02-03T13:16:14Z","relation":"main_file","access_level":"open_access","creator":"cchlebak","file_id":"10720","success":1,"date_updated":"2022-02-03T13:16:14Z","file_size":5595666,"file_name":"2021_AdvancedMaterials_Liu.pdf","checksum":"990bccc527c64d85cf1c97885110b5f4","content_type":"application/pdf"}],"oa_version":"Published Version","project":[{"grant_number":"665385","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program"},{"grant_number":"754411","call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"grant_number":"M02889","_id":"9B8804FC-BA93-11EA-9121-9846C619BF3A","name":"Bottom-up Engineering for Thermoelectric Applications"},{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"}],"article_processing_charge":"Yes (via OA deal)","publication_status":"published","department":[{"_id":"EM-Fac"},{"_id":"MaIb"}],"citation":{"ieee":"Y.

and easily transform within perovskite and nonperovskite structures. In this work, we explore the conversion of the perovskite CsPbBr3 into Cs4PbBr6 in the presence of PbS at 450 °C to produce doped nanocrystal-based composites with embedded Cs4PbBr6 nanoprecipitates. We show that PbBr2 is extracted from CsPbBr3 and diffuses into the PbS lattice with a consequent increase in the concentration of free charge carriers. This new doping strategy enables the adjustment of the density of charge carriers between 1019 and 1020 cm–3, and it may serve as a general strategy for doping other nanocrystal-based semiconductors."}],"_id":"9118","day":"20","publication":"ACS Energy Letters","file_date_updated":"2021-02-17T07:36:52Z","issue":"2","citation":{"short":"M.

Yet, limited effort was devoted to understand the effect of ligand coverage and postsynthesis treatments on CO2 reduction, especially under industrially applicable conditions, such as at high currents (>100 mA/cm2) using gas diffusion electrodes (GDE) and flow reactors. In this work, Cu–Ag core–shell nanoparticles (11 ± 2 nm) were prepared with three different surface modes: (i) capped with oleylamine, (ii) capped with monoisopropylamine, and (iii) surfactant-free with a reducing borohydride agent; Cu–Ag (OAm), Cu–Ag (MIPA), and Cu–Ag (NaBH4), respectively. The ligand exchange and removal was evidenced by infrared spectroscopy (ATR-FTIR) analysis, whereas high-resolution scanning transmission electron microscopy (HAADF-STEM) showed their effect on the interparticle distance and nanoparticle rearrangement. Later on, we developed a process-on-substrate method to track these effects on CO2R. Cu–Ag (OAm) gave a lower on-set potential for hydrocarbon production, whereas Cu–Ag (MIPA) and Cu–Ag (NaBH4) promoted syngas production. The electrochemical impedance and surface area analysis on the well-controlled electrodes showed gradual increases in the electrical conductivity and active surface area after each surface treatment. We found that the increasing amount of the triple phase boundaries (the meeting point for the electron–electrolyte–CO2 reactant) affect the required electrode potential and eventually the C+2e̅/C2e̅ product ratio. This study highlights the importance of the electron transfer to those active sites affected by the capping agents—particularly on larger substrates that are crucial for their industrial application."}],"_id":"8926","day":"20","publication":"ACS Catalysis","issue":"22","department":[{"_id":"MaIb"}],"citation":{"chicago":"Irtem, Erdem, Daniel Arenas Esteban, Miguel Duarte, Daniel Choukroun, Seungho Lee, Maria Ibáñez, Sara Bals, and Tom Breugelmans. “Ligand-Mode Directed Selectivity in Cu-Ag Core-Shell Based Gas Diffusion Electrodes for CO2 Electroreduction.” <i>ACS Catalysis</i>.
