Peroxiredoxins (PRDXs) eliminate reactive oxygen species such as hydrogen peroxide through a catalytic cycle of Cys oxidation and reduction. Additionally, upon Cys oxidation PRDXs undergo extensive conformational rearrangements that may underlie their presently structurally poorly defined functions as molecular chaperones. Rearrangements include high molecular-weight oligomerization, the dynamics of which are, however, poorly understood, as is the impact of disulfide bond formation on these properties. Here we show that formation of disulfide bonds along the catalytic cycle induces extensive microsecond time scale dynamics, as monitored by magic-angle spinning NMR of the 216 kDa-large Tsa1 decameric assembly and solution-NMR of a designed dimeric mutant. We ascribe the conformational dynamics to structural frustration, resulting from conflicts between the disulfide-constrained reduction of mobility and the desire to fulfil other favorable contacts. \r\n\r\nThis data repository contains NMR data presented in the associated manuscript"}],"oa_version":"Published Version","publisher":"Institute of Science and Technology Austria","oa":1,"month":"04"},{"date_updated":"2023-08-01T14:45:25Z","department":[{"_id":"BiCh"}],"_id":"13039","article_type":"original","type":"journal_article","status":"public","publication_status":"published","publication_identifier":{"issn":["2469-9950"],"eissn":["2469-9969"]},"language":[{"iso":"eng"}],"volume":107,"issue":"13","abstract":[{"lang":"eng","text":"We calculate reflectivities of dynamically compressed water, water-ethanol mixtures, and ammonia at infrared and optical wavelengths with density functional theory and molecular dynamics simulations.

The HSE functional offers not only a more accurate description of the electronic band gap but also shifts the onset of molecular dissociation in the molecular dynamics simulations to significantly higher pressures. We also highlight the importance of using accurate reference standards in reflectivity experiments and reanalyze infrared and optical reflectivity data from recent experiments.

We further engineer SnTe–Cu2SnTe3 nanocomposites with a homogeneous phase distribution by decomposing the liquid SnTe precursor containing a dispersion of Cu1.5Te colloidal nanoparticles. The presence of Cu within the SnTe and the segregated semimetallic Cu2SnTe3 phase effectively improves the electrical conductivity of SnTe while simultaneously reducing the lattice thermal conductivity without compromising the Seebeck coefficient.

Most studies have focused on spherical objects, whereas biologically relevant shapes can be highly anisotropic. In this letter, we use an experimental model system based on Giant Unilamellar Vesicles (GUVs) and dumbbell-shaped colloidal particles to mimic and investigate the first stage of the passive endocytic process: engulfment of an anisotropic object by the membrane. Our model has specific ligand–receptor interactions realized by mobile receptors on the vesicles and immobile ligands on the particles. Through a series of experiments, theory, and molecular dynamics simulations, we quantify the wrapping process of anisotropic dumbbells by GUVs and identify distinct stages of the wrapping pathway. We find that the strong curvature variation in the neck of the dumbbell as well as membrane tension are crucial in determining both the speed of wrapping and the final states.","lang":"eng"}],"oa_version":"Published Version","pmid":1,"ec_funded":1,"volume":23,"issue":"10","publication_status":"published","publication_identifier":{"eissn":["1530-6992"],"issn":["1530-6984"]},"language":[{"iso":"eng"}],"file":[{"access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_id":"13100","checksum":"9734d4c617bab3578ef62916b764547a","success":1,"creator":"dernst","date_updated":"2023-05-30T07:55:31Z","file_size":3654910,"date_created":"2023-05-30T07:55:31Z","file_name":"2023_NanoLetters_Azadbakht.pdf"}]},{"date_created":"2023-05-28T22:01:03Z","doi":"10.1021/acsaelm.3c00055","date_published":"2023-05-05T00:00:00Z","publication":"ACS Applied Electronic Materials","day":"05","year":"2023","isi":1,"oa":1,"publisher":"American Chemical Society","quality_controlled":"1","acknowledgement":"Open Access is funded by the Austrian Science Fund (FWF).

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.","lang":"eng"}],"department":[{"_id":"MaIb"}],"date_updated":"2023-08-01T14:50:48Z","status":"public","type":"journal_article","article_type":"original","_id":"13093"},{"acknowledgement":"The authors are grateful to Paul Nelson, Per Salberger and Jason Starr for useful comments.

Tunable directionality can be achieved by applying external magnetic fields that modify optical selection rules, by using nonlinear effects, or interactions with vibrations. However, these approaches are less suitable to control microwave photon propagation inside integrated superconducting quantum devices. Here, we demonstrate on-demand tunable directional scattering based on two periodically modulated transmon qubits coupled to a transmission line at a fixed distance. By changing the relative phase between the modulation tones, we realize unidirectional forward or backward photon scattering. Such an in-situ switchable mirror represents a versatile tool for intra- and inter-chip microwave photonic processors. In the future, a lattice of qubits can be used to realize topological circuits that exhibit strong nonreciprocity or chirality.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"05","intvolume":" 14","date_updated":"2023-08-02T06:10:26Z","ddc":["530"],"department":[{"_id":"JoFi"}],"file_date_updated":"2023-06-06T07:31:20Z","_id":"13117","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public"},{"project":[{"name":"A Fiber Optic Transceiver for Superconducting Qubits","grant_number":"758053","_id":"26336814-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"grant_number":"899354","name":"Quantum Local Area Networks with Superconducting Qubits","call_identifier":"H2020","_id":"9B868D20-BA93-11EA-9121-9846C619BF3A"},{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"name":"Integrating superconducting quantum circuits","grant_number":"F07105","_id":"26927A52-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"},{"_id":"237CBA6C-32DE-11EA-91FC-C7463DDC885E","call_identifier":"H2020","name":"Quantum readout techniques and technologies","grant_number":"862644"},{"name":"Coherent on-chip conversion of superconducting qubit signals from microwaves to optical frequencies","_id":"2671EB66-B435-11E9-9278-68D0E5697425"}],"citation":{"ista":"Sahu R, Qiu L, Hease WJ, Arnold GM, Minoguchi Y, Rabl P, Fink JM. 2023.

This achievement not only paves the way for entanglement between superconducting circuits and telecom wavelength light, but also has wide-ranging implications for hybrid quantum networks in the context of modularization, scaling, sensing, and cross-platform verification."}],"oa_version":"Preprint","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2301.03315"}],"month":"05","intvolume":" 380","publication_identifier":{"issn":["0036-8075"],"eissn":["1095-9203"]},"publication_status":"published","language":[{"iso":"eng"}],"related_material":{"record":[{"id":"13122","status":"public","relation":"research_data"}],"link":[{"relation":"press_release","url":"https://ista.ac.at/en/news/wiring-up-quantum-circuits-with-light/","description":"News on ISTA Website"}]},"issue":"6646","volume":380,"ec_funded":1},{"abstract":[{"text":"We study the representative volume element (RVE) method, which is a method to approximately infer the effective behavior ahom of a stationary random medium. The latter is described by a coefficient field a(x) generated from a given ensemble ⟨⋅⟩ and the corresponding linear elliptic operator −∇⋅a∇. In line with the theory of homogenization, the method proceeds by computing d=3 correctors (d denoting the space dimension). To be numerically tractable, this computation has to be done on a finite domain: the so-called representative volume element, i.e., a large box with, say, periodic boundary conditions. The main message of this article is: Periodize the ensemble instead of its realizations. By this, we mean that it is better to sample from a suitably periodized ensemble than to periodically extend the restriction of a realization a(x) from the whole-space ensemble ⟨⋅⟩. We make this point by investigating the bias (or systematic error), i.e., the difference between ahom and the expected value of the RVE method, in terms of its scaling w.r.t. the lateral size L of the box. In case of periodizing a(x), we heuristically argue that this error is generically O(L−1). In case of a suitable periodization of ⟨⋅⟩\r\n, we rigorously show that it is O(L−d). In fact, we give a characterization of the leading-order error term for both strategies and argue that even in the isotropic case it is generically non-degenerate. We carry out the rigorous analysis in the convenient setting of ensembles ⟨⋅⟩\r\n of Gaussian type, which allow for a straightforward periodization, passing via the (integrable) covariance function. This setting has also the advantage of making the Price theorem and the Malliavin calculus available for optimal stochastic estimates of correctors. We actually need control of second-order correctors to capture the leading-order error term. This is due to inversion symmetry when applying the two-scale expansion to the Green function. As a bonus, we present a stream-lined strategy to estimate the error in a higher-order two-scale expansion of the Green function.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1007/s10208-023-09613-y"}],"month":"05","publication_identifier":{"eissn":["1615-3383"],"issn":["1615-3375"]},"publication_status":"epub_ahead","language":[{"iso":"eng"}],"_id":"13129","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","date_updated":"2023-08-02T06:12:39Z","ddc":["510"],"department":[{"_id":"JuFi"}],"acknowledgement":"Open access funding provided by Institute of Science and Technology (IST Austria).","quality_controlled":"1","publisher":"Springer Nature","oa":1,"isi":1,"has_accepted_license":"1","year":"2023","day":"30","publication":"Foundations of Computational Mathematics","doi":"10.1007/s10208-023-09613-y","date_published":"2023-05-30T00:00:00Z","date_created":"2023-06-11T22:00:40Z","citation":{"short":"N.
