In such applications, the use of solution-processed nanocrystals (NCs) to produce thin films or bulk nanomaterials has associated several potential advantages, such as high material yield and throughput, and composition control with unmatched spatial resolution and cost. Here we report on the production of Cu3SbSe4 (CASe) NCs with tuned amounts of Sn and Bi dopants. After proper ligand removal, as monitored by nuclear magnetic resonance and infrared spectroscopy, these NCs were used to produce dense CASe bulk nanomaterials for solid state TE energy conversion. By adjusting the amount of extrinsic dopants, dimensionless TE figures of merit (ZT) up to 1.26 at 673 K were reached. Such high ZT values are related to an optimized carrier concentration by Sn doping, a minimized lattice thermal conductivity due to efficient phonon scattering at point defects and grain boundaries, and to an increase of the Seebeck coefficient obtained by a modification of the electronic band structure with Bi doping. Nanomaterials were further employed to fabricate ring-shaped TE generators to be coupled to hot pipes, which provided 20 mV and 1 mW per TE element when exposed to a 160 °C temperature gradient. The simple design and good thermal contact associated with the ring geometry and the potential low cost of the material solution processing may allow the fabrication of TE generators with short payback times.","lang":"eng"}],"extern":"1","month":"12","doi":"10.1039/C6TA08467B","date_updated":"2021-01-12T07:51:34Z","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","language":[{"iso":"eng"}],"title":"Solution based synthesis and processing of Sn and Bi doped Cu inf 3 inf SbSe inf 4 inf nanocrystals nanomaterials and ring shaped thermoelectric generators","citation":{"chicago":"Liu, Yu, Gregorio García, Silvia Ortega, Doris Cadavid, Pablo Palacios, Jinyu Lu, Maria Ibanez, et al. “Solution Based Synthesis and Processing of Sn and Bi Doped Cu Inf 3 Inf SbSe Inf 4 Inf Nanocrystals Nanomaterials and Ring Shaped Thermoelectric Generators.” <i>Journal of Materials Chemistry A</i>.

In this work, we show how colloidal chemistry is an excellent synthetic choice for the synthesis of novel ternary nanostructured chalcogenides, containing exclusively noble metals, with tailored morphology and composition and with potential application in the energy conversion field. Specifically, the Ag-Au-Se system has been explored from a synthetic point of view, which leads to a set of Ag2Se-based hybrid and ternary nanoparticles including the room temperature synthesis of the rare ternary Ag3AuSe2 fischesserite phase. An in-depth structural and chemical characterization of all nanomaterials has been performed, which proofed especially useful for unravelling the reaction mechanism behind the formation of the ternary phase in solution. The work is complemented with the thermal and electric characterization of a ternary Ag-Au-Se nanocomposite with promising results: we found that the use of the ternary nanocomposite represents a clear improvement in terms of thermoelectric energy conversion as compared to a binary Ag-Se nanocomposite analogue.

Lead chalcogenide QDs are known to crystallize in the rock-salt structure, although with very different atomic order and stoichiometry in the core and surface regions; however, there exists no convincing prior identification of how extreme downsizing and surface-induced ligand effects influence structural distortion. Using forefront X-ray scattering techniques and density functional theory calculations, here we have identified that, at sizes below 8 nm, PbS and PbSe QDs undergo a lattice distortion with displacement of the Pb sublattice, driven by ligand-induced tensile strain. The resulting permanent electric dipoles may have implications on the oriented attachment of these QDs. Evidence is found for a Pb-deficient core and, in the as-synthesized QDs, for a rhombic dodecahedral shape with nonpolar {110} facets.

Here, we present our experimental results on the thermal and electrical transport properties of PbS-metal composites produced by a versatile particle blending procedure, and where the metal work function allows injecting electrons to the intrinsic PbS host. We compare the thermoelectric performance of composites with microcrystalline or nanocrystalline structures. The electrical conductivity of the microcrystalline host can be increased several orders of magnitude with the metal inclusion, while relatively high Seebeck coefficient can be simultaneously conserved. On the other hand, in nanostructured materials, the host crystallites are not able to sustain a band bending at its interface with the metal, becoming flooded with electrons. This translates into even higher electrical conductivities than the microcrystalline material, but at the expense of lower Seebeck coefficient values.","lang":"eng"}],"_id":"383","date_published":"2016-08-29T00:00:00Z","date_created":"2018-12-11T11:46:09Z","month":"08","extern":"1"},{"_id":"389","date_published":"2016-04-01T00:00:00Z","abstract":[{"text":"The coherent optical manipulation of solids is emerging as a promising way to engineer novel quantum states of matter. The strong time-periodic potential of intense laser light can be used to generate hybrid photon-electron states. Interaction of light with Bloch states leads to Floquet-Bloch states, which are essential in realizing new photo-induced quantum phases. Similarly, dressing of free-electron states near the surface of a solid generates Volkov states, which are used to study nonlinear optics in atoms and semiconductors. The interaction of these two dynamic states with each other remains an open experimental problem. Here we use time- and angle-resolved photoemission spectroscopy (Tr-ARPES) to selectively study the transition between these two states on the surface of the topological insulator Bi2Se3. We find that the coupling between the two strongly depends on the electron momentum, providing a route to enhance or inhibit it. Moreover, by controlling the light polarization we can negate Volkov states to generate pure Floquet-Bloch states.

Recently, it has become clear that a charge density wave (CDW) phase exists within the pseudogap regime. This CDW coexists and competes with superconductivity (SC) below the transition temperature Tc, suggesting that these two orders are intimately related. Here we show that the condensation of the superfluid from this unconventional precursor is reflected in deviations from the predictions of BSC theory regarding the recombination rate of quasiparticles. We report a detailed investigation of the quasiparticle (QP) recombination lifetime, τqp, as a function of temperature and magnetic field in underdoped HgBa2CuO4+δ (Hg-1201) and YBa2Cu3O6+x (YBCO) single crystals by ultrafast time-resolved reflectivity. We find that τqp (T) exhibits a local maximum in a small temperature window near Tc that is prominent in underdoped samples with coexisting charge order and vanishes with application of a small magnetic field. We explain this unusual, non-BCS behavior by positing that Tc marks a transition from phase-fluctuating SC/CDW composite order above to a SC/CDW condensate below. Our results suggest that the superfluid in underdoped cuprates is a condensate of coherently-mixed particle-particle and particle-hole pairs.","lang":"eng"}]},{"year":"2015","author":[{"orcid":"0000-0002-8314-0177","id":"35827D50-F248-11E8-B48F-1D18A9856A87","last_name":"Browning","full_name":"Timothy Browning","first_name":"Timothy D"},{"full_name":"Munshi, Ritabrata","first_name":"Ritabrata","last_name":"Munshi"}],"type":"journal_article","publist_id":"7645","day":"10","title":"Pairs of diagonal quadratic forms and linear correlations among sums of two squares","citation":{"ieee":"T.

Compared to lithium or sodium, metallic magnesium anode is safer due to dendrite-free electroplating and offers extremely high volumetric (3833 mAh cm-3) and gravimetric capacities (2205 mAh g-1). Na-ion cathodes, FeS2 NCs in the present study, may serve as attractive alternatives to Mg-ion cathodes due to the higher voltage of operation and fast, highly reversible insertion of Na-ions. In this proof-of-concept study, electrochemical cycling of the Na/Mg hybrid battery was characterized by high rate capability, high Coulombic efficiency of 99.8%, and high energy density. In particular, with an average discharge voltage of ∼1.1 V and a cathodic capacity of 189 mAh g-1 at a current of 200 mA g-1, the presented Mg/FeS2 hybrid battery delivers energy densities of up to 210 Wh kg-1, comparable to commercial Li-ion batteries and approximately twice as high as state-of-the-art Mg-ion batteries based on Mo6S8 cathodes. Further significant gains in the energy density are expected from the development of Na/Mg electrolytes with a broader electrochemical stability window. Fully based on Earth-abundant elements, hybrid Na-Mg batteries are highly promising for large-scale stationary energy storage.

For instance, they can be used to predict the population evolution starting from different initial conditions or to test how a system responds to external perturbations. For this analysis to be meaningful in real applications, however, it is of paramount importance to choose an appropriate model structure and to infer the model parameters from measured data. While many parameter inference methods are available for models based on deterministic ordinary differential equations, the same does not hold for more detailed individual-based models. Here we consider, in particular, stochastic models in which the time evolution of the species abundances is described by a continuous-time Markov chain. These models are governed by a master equation that is typically difficult to solve. Consequently, traditional inference methods that rely on iterative evaluation of parameter likelihoods are computationally intractable. The aim of this paper is to present recent advances in parameter inference for continuous-time Markov chain models, based on a moment closure approximation of the parameter likelihood, and to investigate how these results can help in understanding, and ultimately controlling, complex systems in ecology. Specifically, we illustrate through an agricultural pest case study how parameters of a stochastic individual-based model can be identified from measured data and how the resulting model can be used to solve an optimal control problem in a stochastic setting. In particular, we show how the matter of determining the optimal combination of two different pest control methods can be formulated as a chance constrained optimization problem where the control action is modeled as a state reset, leading to a hybrid system formulation."}],"_id":"10794","date_published":"2015-06-10T00:00:00Z","file":[{"file_name":"2015_FrontiersEnvironmScience_Parise.pdf","creator":"dernst","file_size":1371201,"checksum":"26c222487564e1be02a11d688d6f769d","date_updated":"2022-02-25T11:55:26Z","access_level":"open_access","content_type":"application/pdf","relation":"main_file","file_id":"10795","date_created":"2022-02-25T11:55:26Z","success":1}],"article_number":"42","oa":1,"publication_status":"published","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)"},"volume":3,"file_date_updated":"2022-02-25T11:55:26Z"},{"page":"1018-1029","month":"01","date_created":"2022-02-25T12:18:43Z","publisher":"SIAM","department":[{"_id":"KrCh"}],"quality_controlled":"1","publication":"Proceedings of the Twenty-Sixth Annual ACM-SIAM Symposium on Discrete Algorithms","status":"public","intvolume":"      2015","ec_funded":1,"citation":{"apa":"Chatterjee, K., &#38; Ibsen-Jensen, R.

The disease phenotype comprises characteristic circumferential skin creases accompanied by intellectual disability, a cleft palate, short stature, and dysmorphic features. Here, we report that mutations in either MAPRE2 or TUBB underlie the genetic origin of this syndrome. MAPRE2 encodes a member of the microtubule end-binding family of proteins that bind to the guanosine triphosphate cap at growing microtubule plus ends, and TUBB encodes a β-tubulin isotype that is expressed abundantly in the developing brain. Functional analyses of the TUBB mutants show multiple defects in the chaperone-dependent tubulin heterodimer folding and assembly pathway that leads to a compromised yield of native heterodimers. The TUBB mutations also have an impact on microtubule dynamics. For MAPRE2, we show that the mutations result in enhanced MAPRE2 binding to microtubules, implying an increased dwell time at microtubule plus ends. Further, in vivo analysis of MAPRE2 mutations in a zebrafish model of craniofacial development shows that the variants most likely perturb the patterning of branchial arches, either through excessive activity (under a recessive paradigm) or through haploinsufficiency (dominant de novo paradigm). Taken together, our data add CSC-KT to the growing list of tubulinopathies and highlight how multiple inheritance paradigms can affect dosage-sensitive biological systems so as to result in the same clinical defect."}],"_id":"1106","date_published":"2015-12-03T00:00:00Z","date_created":"2018-12-11T11:50:11Z","month":"12","extern":"1","issue":"6","page":"790 - 800","intvolume":"        97","status":"public","volume":97,"publication":"The American Journal of Human Genetics","quality_controlled":"1","publisher":"Cell Press","publication_status":"published","author":[{"last_name":"Isrie","full_name":"Isrie, Mala","first_name":"Mala"},{"last_name":"Breuss","first_name":"Martin","full_name":"Breuss, Martin"},{"first_name":"Guoling","full_name":"Tian, Guoling","last_name":"Tian"},{"id":"38853E16-F248-11E8-B48F-1D18A9856A87","last_name":"Hansen","first_name":"Andi H","full_name":"Hansen, Andi H"},{"last_name":"Cristofoli","full_name":"Cristofoli, Francesca","first_name":"Francesca"},{"id":"4739D480-F248-11E8-B48F-1D18A9856A87","last_name":"Morandell","first_name":"Jasmin","full_name":"Morandell, Jasmin"},{"full_name":"Kupchinsky, Zachari A","first_name":"Zachari A","last_name":"Kupchinsky"},{"first_name":"Alejandro","full_name":"Sifrim, Alejandro","last_name":"Sifrim"},{"full_name":"Rodriguez Rodriguez, Celia","first_name":"Celia","last_name":"Rodriguez Rodriguez"},{"last_name":"Dapena","full_name":"Dapena, Elena P","first_name":"Elena P"},{"first_name":"Kurston","full_name":"Doonanco, Kurston","last_name":"Doonanco"},{"last_name":"Leonard","first_name":"Norma","full_name":"Leonard, Norma"},{"last_name":"Tinsa","first_name":"Faten","full_name":"Tinsa, Faten"},{"last_name":"Moortgat","first_name":"Stéphanie","full_name":"Moortgat, Stéphanie"},{"last_name":"Ulucan","full_name":"Ulucan, Hakan","first_name":"Hakan"},{"full_name":"Koparir, Erkan","first_name":"Erkan","last_name":"Koparir"},{"first_name":"Ender","full_name":"Karaca, Ender","last_name":"Karaca"},{"last_name":"Katsanis","full_name":"Katsanis, Nicholas","first_name":"Nicholas"},{"full_name":"Marton, Valeria","first_name":"Valeria","last_name":"Marton"},{"last_name":"Vermeesch","full_name":"Vermeesch, Joris R","first_name":"Joris R"},{"first_name":"Erica E","full_name":"Davis, Erica E","last_name":"Davis"},{"last_name":"Cowan","first_name":"Nicholas J","full_name":"Cowan, Nicholas J"},{"last_name":"Keays","first_name":"David","full_name":"Keays, David"},{"last_name":"Van Esch","full_name":"Van Esch, Hilde","first_name":"Hilde"}],"type":"journal_article","oa_version":"None","year":"2015","day":"03","publist_id":"6264","title":"Mutations in either TUBB or MAPRE2 cause circumferential skin creases Kunze type","citation":{"short":"M.
