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."}],"citation":{"short":"D.

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.","lang":"eng"}],"ddc":["540"],"article_type":"original","oa":1,"month":"06","date_published":"2019-06-25T00:00:00Z","ec_funded":1,"date_created":"2019-06-18T13:54:34Z","file":[{"date_created":"2019-07-16T14:17:09Z","file_name":"2019_ACSNano_Ibanez.pdf","file_size":8628690,"creator":"dernst","relation":"main_file","file_id":"6644","access_level":"open_access","content_type":"application/pdf","date_updated":"2020-07-14T12:47:33Z"}],"external_id":{"isi":["000473248300043"],"pmid":["31185159"]},"status":"public","issue":"6","language":[{"iso":"eng"}],"quality_controlled":"1","doi":"10.1021/acsnano.9b00346","oa_version":"Published Version","author":[{"orcid":"0000-0001-5013-2843","full_name":"Ibáñez, Maria","id":"43C61214-F248-11E8-B48F-1D18A9856A87","first_name":"Maria","last_name":"Ibáñez"},{"full_name":"Genç, Aziz","first_name":"Aziz","last_name":"Genç"},{"full_name":"Hasler, Roger","last_name":"Hasler","first_name":"Roger"},{"first_name":"Yu","last_name":"Liu","id":"2A70014E-F248-11E8-B48F-1D18A9856A87","full_name":"Liu, Yu","orcid":"0000-0001-7313-6740"},{"first_name":"Oleksandr","last_name":"Dobrozhan","full_name":"Dobrozhan, Oleksandr"},{"first_name":"Olga","last_name":"Nazarenko","full_name":"Nazarenko, Olga"},{"first_name":"María de la","full_name":"Mata, María de la","last_name":"Mata"},{"last_name":"Arbiol","full_name":"Arbiol, Jordi","first_name":"Jordi"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"},{"first_name":"Maksym V.","full_name":"Kovalenko, Maksym V.","last_name":"Kovalenko"}],"publication_identifier":{"issn":["1936-0851"],"eissn":["1936-086X"]},"publication":"ACS Nano","year":"2019","date_updated":"2025-04-14T07:44:06Z","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"6566","title":"Tuning transport properties in thermoelectric nanocomposites through inorganic ligands and heterostructured building blocks","has_accepted_license":"1","project":[{"call_identifier":"H2020","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships"}],"isi":1,"volume":13,"type":"journal_article"},{"date_created":"2018-12-11T11:46:04Z","OA_type":"closed access","date_published":"2016-08-11T00:00:00Z","oa_version":"None","doi":"10.1007/s11051-016-3545-4","quality_controlled":"1","language":[{"iso":"eng"}],"status":"public","date_updated":"2026-05-18T09:21:57Z","year":"2016","publist_id":"7461","publication_identifier":{"eissn":["1572-896X"],"issn":["1388-0764"]},"publication":"Journal of Nanoparticle Research","author":[{"id":"43C61214-F248-11E8-B48F-1D18A9856A87","full_name":"Ibáñez, Maria","first_name":"Maria","last_name":"Ibáñez","orcid":"0000-0001-5013-2843"},{"full_name":"Berestok, Taisiia","first_name":"Taisiia","last_name":"Berestok"},{"first_name":"Oleksandr","last_name":"Dobrozhan","full_name":"Dobrozhan, Oleksandr"},{"full_name":"Lalonde, Aaron","first_name":"Aaron","last_name":"Lalonde"},{"full_name":"Izquierdo Roca, Victor","last_name":"Izquierdo Roca","first_name":"Victor"},{"first_name":"Alexey","last_name":"Shavel","full_name":"Shavel, Alexey"},{"full_name":"Pérez Rodríguez, Alejandro","last_name":"Pérez Rodríguez","first_name":"Alejandro"},{"first_name":"G Jeffrey","full_name":"Snyder, G Jeffrey","last_name":"Snyder"},{"full_name":"Cabot, Andreu","last_name":"Cabot","first_name":"Andreu"}],"title":"Phosphonic acids aid composition adjustment in the synthesis of Cu2+xZn1−xSnSe4−y nanoparticles","_id":"367","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":18,"type":"journal_article","keyword":["CZTSe","Nanostructured materials","Colloidal synthesis","Composition control","Electrical transport:  Thermoelectric"],"intvolume":"        18","publisher":"Springer Nature","article_number":"226","article_processing_charge":"No","publication_status":"published","extern":"1","day":"11","article_type":"original","abstract":[{"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.

This cation-exchange-based synthesis protocol opens up a new approach to design novel heterostructured NPs as efficient nonprecious metal bifunctional oxygen catalysts.","lang":"eng"}],"article_type":"original","pmid":1,"page":"17435 - 17444","day":"20","main_file_link":[{"open_access":"1","url":"https://hdl.handle.net/2117/104566"}],"month":"06","oa":1,"publisher":"American Chemical Society","intvolume":"         8","keyword":["nanoparticle","ORR","OER","manganese oxide","cobalt oxide","colloidal","electrocatalysis","cation exchange"],"OA_place":"repository","publication_status":"published","extern":"1","article_processing_charge":"No","scopus_import":"1"},{"OA_type":"closed access","date_published":"1998-01-01T00:00:00Z","date_created":"2026-03-30T12:22:47Z","external_id":{"pmid":[" 9678876"]},"language":[{"iso":"eng"}],"status":"public","issue":"1-3","doi":"10.1016/s0142-9612(97)00243-3","oa_version":"None","quality_controlled":"1","publication_identifier":{"issn":["0142-9612"]},"publication":"Biomaterials","author":[{"full_name":"Breton, P","first_name":"P","last_name":"Breton"},{"first_name":"X","full_name":"Guillon, X","last_name":"Guillon"},{"first_name":"D","last_name":"Roy","full_name":"Roy, D"},{"first_name":"F","full_name":"Lescure, F","last_name":"Lescure"},{"last_name":"Riess","first_name":"G","full_name":"Riess, G"},{"first_name":"N","last_name":"Bru","full_name":"Bru, N"},{"full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","last_name":"Roques-Carmes","first_name":"Charles"}],"date_updated":"2026-04-15T12:48:31Z","year":"1998","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Physico-chemical characterization, preparation and performance of poly (methylidene malonate 2.1.2) nanoparticles","_id":"21518","type":"journal_article","volume":19,"keyword":["Colloid physico-chemical analysis","Colloidal drug carriers","MALDI-TOF spectroscopy","Nanoparticles","Poly(methylidene malonate)","Scanning electron microscopy"],"publisher":"Elsevier","intvolume":"        19","article_processing_charge":"No","scopus_import":"1","extern":"1","publication_status":"published","pmid":1,"page":"271-281","day":"01","citation":{"short":"P.

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.","lang":"eng"}],"article_type":"original","ddc":["530"],"month":"01"}]
