Providing reliable and statistically meaningful information on their average nanostructure is essential for synthesis control and applications. In this paper, we propose a novel procedure that simplifies and makes more effective the electron powder diffraction-based Rietveld analysis of nanomaterials. Our single step in-TEM method allows to obtain the instrumental broadening function of the TEM directly from a single measurement without the need for an additional X-ray diffraction measurement. Using a multilayer graphene calibration standard and applying properly controlled acquisition conditions on a spherical aberration-corrected microscope, we achieved the instrumental broadening of ±0.01 Å in terms of interplanar spacing. The shape of the diffraction peaks is modeled as a function of the scattering angle using the Caglioti relation, and the obtained parameters for instrumental broadening can be directly applied in the Rietveld analysis of electron diffraction data of the analyzed specimen. During peak shape analysis, the instrumental broadening parameters of the TEM are controlled separately from nanostructure-related peak broadening effects, which contribute to the higher reliability of nanostructure information extracted from electron diffraction patterns. The potential of the proposed procedure is demonstrated through the Rietveld analysis of hematite nanopowder and two-component Cu-Ni nanocrystalline thin film specimens.}, keywords = {electron diffraction; Nanopowder; Rietveld analysis; nanostructure characterization; instrumental broadening}, year = {2024}, eissn = {2079-4991}, orcid-numbers = {Kovács, Zsolt/0000-0001-6802-3311; Czigány, Zsolt/0000-0001-6410-8801} } @article{MTMT:34629567, title = {Bichromatic Rabi Control of Semiconductor Qubits}, url = {https://m2.mtmt.hu/api/publication/34629567}, author = {John, V. and Borsoi, F. and György, Z. and Wang, C.-A. and Széchenyi, Gábor and Van, Riggelen-Doelman F. and Lawrie, W.I.L. and Hendrickx, N.W. and Sammak, A. and Scappucci, G. and Pályi, András and Veldhorst, M.}, doi = {10.1103/PhysRevLett.132.067001}, journal-iso = {PHYS REV LETT}, journal = {PHYSICAL REVIEW LETTERS}, volume = {132}, unique-id = {34629567}, issn = {0031-9007}, year = {2024}, eissn = {1079-7114}, orcid-numbers = {Széchenyi, Gábor/0000-0002-4039-7546} } @article{MTMT:34628050, title = {Training iterated protocols for distillation of GHZ states with variational quantum algorithms}, url = {https://m2.mtmt.hu/api/publication/34628050}, author = {Rozgonyi, Áron and Széchenyi, Gábor and Kálmán, Orsolya and Kiss, Tamás}, doi = {10.1016/j.physleta.2024.129349}, journal-iso = {PHYS LETT A}, journal = {PHYSICS LETTERS A}, volume = {499}, unique-id = {34628050}, issn = {0375-9601}, year = {2024}, eissn = {1873-2429}, orcid-numbers = {Széchenyi, Gábor/0000-0002-4039-7546; Kálmán, Orsolya/0000-0002-6156-5641} } @article{MTMT:34599260, title = {Mobilisation and analyses of publicly available SARS-CoV-2 data for pandemic responses.}, url = {https://m2.mtmt.hu/api/publication/34599260}, author = {Rahman, Nadim and O'Cathail, Colman and Zyoud, Ahmad and Sokolov, Alexey and Oude Munnink, Bas and Grüning, Björn and Cummins, Carla and Amid, Clara and Nieuwenhuijse, David F and Visontai, David and Yuan, David Yu and Gupta, Dipayan and Prasad, Divyae K and Gulyás, Gábor Máté and Rinck, Gabriele and McKinnon, Jasmine and Rajan, Jeena and Knaggs, Jeff and Skiby, Jeffrey Edward and Stéger, József and Szarvas, Judit and Gueye, Khadim and Papp, Krisztián and Hoek, Maarten and Kumar, Manish and Ventouratou, Marianna A and Bouquieaux, Marie-Catherine and Koliba, Martin and Mansurova, Milena and Haseeb, Muhammad and Worp, Nathalie and Harrison, Peter W and Leinonen, Rasko and Thorne, Ross and Selvakumar, Sandeep and Hunt, Sarah and Venkataraman, Sundar and Jayathilaka, Suran and Cezard, Timothée and Maier, Wolfgang and Waheed, Zahra and Iqbal, Zamin and Aarestrup, Frank Møller and Csabai, István and Koopmans, Marion and Burdett, Tony and Cochrane, Guy}, doi = {10.1099/mgen.0.001188}, journal-iso = {MICROB GENOM}, journal = {MICROBIAL GENOMICS}, volume = {10}, unique-id = {34599260}, issn = {2057-5858}, abstract = {The COVID-19 pandemic has seen large-scale pathogen genomic sequencing efforts, becoming part of the toolbox for surveillance and epidemic research.

In order to achieve a remarkable synergetic effect between the two materials, the amount of the FeTi catalyst was chosen to be 40 wt.%, 50 wt.% and 60 wt.%. The morphology and microstructure of the as-milled powders were characterized by scanning electron microscopy and X-ray diffraction, respectively. The evaluation of the diffraction profiles by the Convolutional Multiple Whole Profile fitting algorithm provided a detailed microstructural characterization of the coherently scattering α-MgH2 crystallites. Differential scanning calorimetry experiments revealed two overlapping endotherms corresponding to the dehydrogenation of metastable γ-MgH2 and stable α-MgH2 hydrides. Isothermal hydrogen-sorption experiments were carried out in a Sieverts-type apparatus. It was established that the MgH2-40 wt.% FeTi powder is capable of absorbing 5.8 wt.% hydrogen, while extraordinary absorption kinetics were observed for the MgH2-50 wt.% FeTi alloy, i.e., 3.3 wt.% H2 is absorbed after 100 s.}, year = {2024}, eissn = {1996-1073}, orcid-numbers = {Spassov, Tony/0000-0002-4568-9273; Nagy, Péter/0000-0003-4266-0384} } @article{MTMT:34555692, title = {Irreversible evolution of dislocation pile-ups during cyclic microcantilever bending}, url = {https://m2.mtmt.hu/api/publication/34555692}, author = {Ugi, Dávid and Zoller, K. and Lukács, K. and Fogarassy, Z. and Groma, István and Kalácska, Szilvia and Schulz, K. and Ispánovity, Péter Dusán}, doi = {10.1016/j.matdes.2024.112682}, journal-iso = {MATER DESIGN}, journal = {MATERIALS AND DESIGN}, volume = {238}, unique-id = {34555692}, issn = {0264-1275}, year = {2024}, eissn = {1873-4197}, orcid-numbers = {Groma, István/0000-0002-6644-1365; Kalácska, Szilvia/0000-0001-5601-5859; Ispánovity, Péter Dusán/0000-0002-9956-0061} } @article{MTMT:34544958, title = {Microstructure Evolution during High-Pressure Torsion in a 7xxx AlZnMgZr Alloy}, url = {https://m2.mtmt.hu/api/publication/34544958}, author = {Ahmed, Anwar Qasim and Olasz, Dániel and Bobruk, Elena V. and Valiev, Ruslan Z. and Nguyen Quang, Chinh}, doi = {10.3390/ma17030585}, journal-iso = {MATERIALS}, journal = {MATERIALS}, volume = {17}, unique-id = {34544958}, abstract = {A homogenized, supersaturated AlZnMgZr alloy was processed via severe plastic deformation (SPD) using a high-pressure torsion (HPT) technique for different revolutions at room temperature to obtain an ultrafine-grained (UFG) microstructure. The microstructure and mechanical properties of the UFG samples were then studied using transmission electron microscopy (TEM), differential scanning calorimetry (DSC), and tensile and hardness measurements. The main purpose was to study the effect of shear strain on the evolution of the microstructure of the investigated alloy. We found a very interesting evolution of the decomposed microstructure in a wide range of shear strains imposed by HPT. While the global properties, such as the average grain size (~200 nm) and hardness (~2200 MPa) appeared unchanged, the local microstructure was continuously transformed. After 1 turn of HPT, the decomposed UFG structure contained relatively large precipitates inside grains. In the sample processed by five turns in HPT, the segregation of Zn atoms into grain boundaries (GBs) was also observed. After 10 turns, more Zn atoms were segregated into GBs and only smaller-sized precipitates were observed inside grains. The intensive solute segregations into GBs may significantly affect the ductility of the material, leading to its ultralow-temperature superplasticity. Our findings pave the way for achieving advanced microstructural and mechanical properties in nanostructured metals and alloys by engineering their precipitation and segregation by means of applying different HPT regimes.}, year = {2024}, eissn = {1996-1944}, orcid-numbers = {Ahmed, Anwar Qasim/0000-0002-8112-5694; Olasz, Dániel/0000-0003-4136-4612; Bobruk, Elena V./0000-0001-8226-9887; Valiev, Ruslan Z./0000-0003-4340-4067; Nguyen Quang, Chinh/0000-0002-6610-7308} }
