It has been shown that resistive switching may also appear in pure metallic nanowires lacking any silver-ion-hosting embedding environment but this pure atomic switching mechanism differs fundamentally from the conventional electrochemical-metallization-based resistive switching. To facilitate the quantitative description of the former phenomenon, we investigate a broad range of Ag atomic junctions, with a special focus on the frequency dependence and the fundamentally stochastic cycle-to-cycle variation of the switching-threshold voltage. These devices are established in an ultrahigh-purity environment in which electrochemical metallization can be excluded. The measured characteristics are successfully described by a vibrational-pumping model, yielding consistent predictions for the weak frequency dependence and the large variance of the switching-threshold voltage. We also demonstrate that electrochemical-metallization-based resistive switching and pure atomic switching may appear in the same device structure and therefore the proper understanding of the pure atomic switching mechanism has a very relevant importance in silver-based electrochemical-metallization cells. © 2024 American Physical Society.}, keywords = {SILVER; NANOWIRES; Atoms; metal ions; stochastic systems; Threshold voltage; Switching mechanism; silver nanowires; resistive switching; metallisation; stochastics; Electrochemicals; Frequencies dependence; Atomic switches; Switching threshold voltage; Threshold voltage variation}, year = {2024}, eissn = {2331-7019}, orcid-numbers = {Vigh, Máté/0000-0001-5668-7735; Halbritter, András Ernő/0000-0003-4837-9745} } @article{MTMT:34428880, title = {In Situ Observation of Perovskite Quantum Dots Driven by Photopolymerization Controlled Using a Digital Micromirror Device}, url = {https://m2.mtmt.hu/api/publication/34428880}, author = {Tanaka, H. and Lagzi, István László and Nakanishi, H.}, doi = {10.1002/adom.202302574}, journal-iso = {ADV OPT MATER}, journal = {ADVANCED OPTICAL MATERIALS}, volume = {12}, unique-id = {34428880}, issn = {2195-1071}, year = {2024}, eissn = {2195-1071} } @article{MTMT:33836337, title = {Novel manufacturing method for highly flexible poly(lactic acid) foams and ferroelectrets}, url = {https://m2.mtmt.hu/api/publication/33836337}, author = {Vadas, Dániel and Bordácsné Bocz, Katalin and Igricz, Tamás and Volk, János and Bordács, Sándor and Madarász, Lajos and Marosi, György}, doi = {10.1016/j.aiepr.2023.03.005}, journal-iso = {ADV INDUST ENGIN POLYMER RES}, journal = {ADVANCED INDUSTRIAL AND ENGINEERING POLYMER RESEARCH}, volume = {7}, unique-id = {33836337}, issn = {2542-5048}, abstract = {Poly (lactic acid) (PLA) foams have demonstrated a high variety of functional characteristics, still, the rigidity of this cellular material remains a major limiting factor when it comes to implementation options. In this contribution, PLA foams with outstanding flexibility were created for the first time by a new approach of uniaxial stretching and immediate relaxation following supercritical CO2-assisted extrusion foaming. Instead of improving the resilience of the PLA raw material, structural elasticity of the foam was achieved via altering the deformation mechanism from cell wall collapse or rupture towards reversible and extensive flexural strain. In addition, PLA foams with excellent piezoelectric properties were also achieved via high-voltage corona poling, giving additional function to the lens-like anisotropic foam cells. This foaming technology creates the opportunity to produce PLA piezoelectrets in a way entirely different from the state-of-the-art methods. Correlation between the tensile as well as compression elongations and moduli, cell morphology and longitudinal piezoelectric coefficients (d33) of electretized foam samples were studied. Unprecedented reversible tensile elongations of up to 16% and total elongations of up to 35% were reached, as well as considerable d33 values in the range of 50–320 pC/N were obtained for PLA ferroelectrets.}, year = {2024}, pages = {215-225}, orcid-numbers = {Volk, János/0000-0003-3633-6190; Bordács, Sándor/0000-0003-0420-5997; Marosi, György/0000-0002-4774-2023} } @article{MTMT:34448213, title = {Up-and-down motion of a Belousov-Zhabotinsky bead in couple with chemical oscillation}, url = {https://m2.mtmt.hu/api/publication/34448213}, author = {Kubodera, Yujin and Kuze, Masakazu and Kagawa, Kazuhiro and Muneyuki, Matsuo and Lagzi, István László and Suematsu, Nobuhiko and Nakata, Satoshi}, doi = {10.3389/fphy.2023.1306533}, journal-iso = {FRONT PHYS-LAUSANNE}, journal = {FRONTIERS IN PHYSICS}, volume = {11}, unique-id = {34448213}, year = {2023}, eissn = {2296-424X}, pages = {1306533-1306537} } @article{MTMT:34417514, title = {Complex Patterning of Matter with Liesegang Patterns Propagating through Different Concentration Media─Gel Lenses for Liesegang Waves}, url = {https://m2.mtmt.hu/api/publication/34417514}, author = {Akbulut, Elif Sila and Holló, Gábor and Lagzi, István László and Baytekin, Bilge}, doi = {10.1021/acs.cgd.3c00871}, journal-iso = {CRYST GROWTH DES}, journal = {CRYSTAL GROWTH & DESIGN}, volume = {23}, unique-id = {34417514}, issn = {1528-7483}, abstract = {The patterns formed in natural biochemical and geochemical media are never spatially or geometrically homogeneous. On the other hand, the artificial systems trying to mimic nature are usually homogeneous and far from depicting the complexity of the natural ones. Liesegang patterns (LPs) are artificial reaction-diffusion precipitate patterns that can be formed in hydrogels. Although these patterns can be made to “sense” the environment, they are mostly formed in homogeneous media. Here, we present that a simple setting of different gel concentration boundaries can cause refractions of the pattern waves and changes in the band spacings. The extent of refraction is dependent on the macroscopic shape of the boundary. As imaged by scanning electron microscopy, the LP bands “crossing the boundaries” are formed by the product of a new morphology. This study can be a step forward in straightforwardly achieving complexity in artificial systems and developing new crystal forms of solids. © 2023 American Chemical Society.}, keywords = {scanning electron microscopy; Refraction; LIESEGANG PATTERNS; Reaction-diffusion; Liesegang; Artificial systems}, year = {2023}, eissn = {1528-7505}, pages = {8718-8725}, orcid-numbers = {Holló, Gábor/0000-0001-9920-4801; Lagzi, István László/0000-0002-2303-5965; Baytekin, Bilge/0000-0002-3867-3863} } @article{MTMT:34396722, title = {Formation of Precipitation Ellipsoidal Disks and Spheres in the Wake of a Planar Diffusion Front}, url = {https://m2.mtmt.hu/api/publication/34396722}, author = {Farkas, Szabolcs and Gazdag, Ferenc and Detrich, Márton and Mészáros, Márton and Holló, Gábor and Schuszter, Gábor and Lagzi, István László}, doi = {10.1021/acs.jpclett.3c02295}, journal-iso = {J PHYS CHEM LETT}, journal = {JOURNAL OF PHYSICAL CHEMISTRY LETTERS}, volume = {14}, unique-id = {34396722}, issn = {1948-7185}, year = {2023}, pages = {10382-10387}, orcid-numbers = {Schuszter, Gábor/0000-0002-9170-9933; Lagzi, István László/0000-0002-2303-5965} } @article{MTMT:34190845, title = {Oppositely Charged Nanoparticles Precipitate Not Only at the Point of Overall Electroneutrality}, url = {https://m2.mtmt.hu/api/publication/34190845}, author = {Itatani, Masaki and Holló, Gábor and Zámbó, Dániel and Nakanishi, Hideyuki and Deák, András and Lagzi, István László}, doi = {10.1021/acs.jpclett.3c01857}, journal-iso = {J PHYS CHEM LETT}, journal = {JOURNAL OF PHYSICAL CHEMISTRY LETTERS}, volume = {14}, unique-id = {34190845}, issn = {1948-7185}, year = {2023}, pages = {9003-9010}, orcid-numbers = {Itatani, Masaki/0000-0003-1025-0452; Holló, Gábor/0000-0001-9920-4801; Nakanishi, Hideyuki/0000-0001-8065-6373; Deák, András/0000-0002-2526-1245; Lagzi, István László/0000-0002-2303-5965} } @article{MTMT:34157346, title = {A Quasi Universal Matalon–Packter Law for a Periodically Precipitating System of Iron(II) Hydroxide Involving Volumes and Concentrations of the Invading Electrolyte}, url = {https://m2.mtmt.hu/api/publication/34157346}, author = {Walimbe, Prasad and Itatani, Masaki and Kulkarni, Preeti and Lagzi, István László and Kulkarni, Sunil}, doi = {10.1021/acs.langmuir.3c00778}, journal-iso = {LANGMUIR}, journal = {LANGMUIR}, volume = {39}, unique-id = {34157346}, issn = {0743-7463}, year = {2023}, eissn = {1520-5827}, pages = {13420-13429}, orcid-numbers = {Itatani, Masaki/0000-0003-1025-0452; Kulkarni, Preeti/0000-0002-8604-878X; Lagzi, István László/0000-0002-2303-5965; Kulkarni, Sunil/0000-0001-6555-837X} } @article{MTMT:34125314, title = {Synthesis of Zeolitic Imidazolate Framework-8 Using Glycerol Carbonate}, url = {https://m2.mtmt.hu/api/publication/34125314}, author = {Itatani, Masaki and Német, Norbert and Valletti, Nadia and Schuszter, Gábor and Prete, Prisco and Lo Nostro, Pierandrea and Cucciniello, Raffaele and Rossi, Federico and Lagzi, István László}, doi = {10.1021/acssuschemeng.3c02876}, journal-iso = {ACS SUSTAIN CHEM ENG}, journal = {ACS SUSTAINABLE CHEMISTRY & ENGINEERING}, volume = {11}, unique-id = {34125314}, issn = {2168-0485}, year = {2023}, eissn = {2168-0485}, pages = {13043-13049}, orcid-numbers = {Itatani, Masaki/0000-0003-1025-0452; Schuszter, Gábor/0000-0002-9170-9933; Cucciniello, Raffaele/0000-0002-3291-7273; Rossi, Federico/0000-0002-1854-532X; Lagzi, István László/0000-0002-2303-5965} } @article{MTMT:34111629, title = {Cover Feature: A Dormant Reagent Reaction‐Diffusion Method for the Generation of Co‐Fe Prussian Blue Analogue Periodic Precipitate Particle Libraries (Chem.
