The assessment of the layer and the interface qualities for a buried strained Ge layer embedded in Si0.3Ge0.7 layers is reported. The XRD reciprocal space mapping confirmed that the reduction of the growth temperature enables the 2-dimensional growth of the Ge layer fully strained with respect to the Si0.3Ge0.7. Nevertheless, dislocations at the top and/or bottom interface of the Ge layer were observed by means of electron channeling contrast imaging, suggesting the importance of the careful dislocation assessment. The interface abruptness does not depend on the selection of the precursor gases, but it is strongly influenced by the growth temperature which affects the coverage of the surface H-passivation. The mobility of 2.7 × 105 cm2/Vs is promising, while the low percolation density of 3 × 1010 /cm2 measured with a Hall-bar device at 7 K illustrates the high quality of the heterostructure thanks to the high Si0.3Ge0.7 SRB quality."}],"oa_version":"Published Version","publication_status":"epub_ahead","day":"20","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)"},"license":"https://creativecommons.org/licenses/by/4.0/","status":"public","date_updated":"2024-02-26T10:36:35Z","volume":174,"article_type":"original","quality_controlled":"1","publication_identifier":{"issn":["1369-8001"]},"month":"02","keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","General Materials Science"],"intvolume":"       174","ddc":["530"],"article_processing_charge":"No","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"GeKa"},{"_id":"NanoFab"}],"acknowledgement":"The Ge project received funding from the European Union's Horizon Europe programme under the Grant Agreement 101069515 – IGNITE.

Herein, FeCoNiMoW HEA nanoparticles are synthesized using a solution‐based low‐temperature approach. Such FeCoNiMoW nanoparticles show high entropy properties, subtle lattice distortions, and modulated electronic structure, leading to superior OER performance with an overpotential of 233 mV at 10 mA cm<jats:sup>−2</jats:sup> and 276 mV at 100 mA cm<jats:sup>−2</jats:sup>. Density functional theory calculations reveal the electronic structures of the FeCoNiMoW active sites with an optimized d‐band center position that enables suitable adsorption of OOH* intermediates and reduces the Gibbs free energy barrier in the OER process. Aqueous zinc–air batteries (ZABs) based on this HEA demonstrate a high open circuit potential of 1.59 V, a peak power density of 116.9 mW cm<jats:sup>−2</jats:sup>, a specific capacity of 857 mAh g<jats:sub>Zn</jats:sub><jats:sup>−1</jats:sup><jats:sub>,</jats:sub> and excellent stability for over 660 h of continuous charge–discharge cycles.

However, sluggish ionic transport kinetics and the unstable electrode structure during ionic insertion/extraction hampers their deployment. Herein,  we propose a new cathode material based on a layered metal chalcogenide (LMC), bismuth telluride (Bi<jats:sub>2</jats:sub>Te<jats:sub>3</jats:sub>), coated with polypyrrole (PPy). Taking advantage of the PPy coating, the Bi<jats:sub>2</jats:sub>Te<jats:sub>3</jats:sub>@PPy composite presents strong ionic absorption affinity, high oxidation resistance, and high structural stability. The ZIBs based on Bi<jats:sub>2</jats:sub>Te<jats:sub>3</jats:sub>@PPy cathodes exhibit high capacities and ultra‐long lifespans of over 5000 cycles. They also present outstanding stability even under bending. In addition,  we analyze here the reaction mechanism using in situ X‐ray diffraction, X‐ray photoelectron spectroscopy, and computational tools and demonstrate that, in the aqueous system, Zn<jats:sup>2+</jats:sup> is not inserted into the cathode as previously assumed. In contrast, proton charge storage dominates the process. Overall, this work not only shows the great potential of LMCs as ZIBs cathode materials and the advantages of PPy coating, but also clarifies the charge/discharge mechanism in rechargeable ZIBs based on LMCs."}],"publication_status":"accepted","oa_version":"None","date_published":"2023-08-09T00:00:00Z","day":"09","_id":"14435","author":[{"first_name":"Guifang","full_name":"Zeng, Guifang","last_name":"Zeng"},{"last_name":"Sun","full_name":"Sun, Qing","first_name":"Qing"},{"last_name":"Horta","id":"03a7e858-01b1-11ec-8b71-99ae6c4a05bc","first_name":"Sharona","full_name":"Horta, Sharona"},{"last_name":"Wang","first_name":"Shang","full_name":"Wang, Shang"},{"last_name":"Lu","full_name":"Lu, Xuan","first_name":"Xuan"},{"last_name":"Zhang","first_name":"Chaoyue","full_name":"Zhang, Chaoyue"},{"last_name":"Li","full_name":"Li, Jing","first_name":"Jing"},{"last_name":"Li","first_name":"Junshan","full_name":"Li, Junshan"},{"full_name":"Ci, Lijie","first_name":"Lijie","last_name":"Ci"},{"last_name":"Tian","first_name":"Yanhong","full_name":"Tian, Yanhong"},{"full_name":"Ibáñez, Maria","first_name":"Maria","last_name":"Ibáñez","id":"43C61214-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-5013-2843"},{"last_name":"Cabot","first_name":"Andreu","full_name":"Cabot, Andreu"}],"type":"journal_article","status":"public","publisher":"Wiley","date_updated":"2023-12-13T13:03:53Z","year":"2023","language":[{"iso":"eng"}],"doi":"10.1002/adma.202305128"},{"isi":1,"article_type":"original","volume":108,"month":"06","quality_controlled":"1","publication_identifier":{"issn":["0924-090X"],"eissn":["1573-269X"]},"article_processing_charge":"Yes (via OA deal)","ddc":["530"],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","file_date_updated":"2022-08-05T06:13:19Z","keyword":["Electrical and Electronic Engineering","Applied Mathematics","Mechanical Engineering","Ocean Engineering","Aerospace Engineering","Control and Systems Engineering"],"intvolume":"       108","date_created":"2022-05-02T07:01:59Z","acknowledgement":"The authors thank Enrique Calisto,Michal Kowalczyk, and Michel Ferre for fructified discussions.

In case these systems are described by vectorial fields, domains can be connected through topological defects. Vortices are one of the most frequent and studied topological defect points. Optical vortices are equally relevant for their fundamental features as beams with topological features and their applications in image processing, telecommunications, optical tweezers, and quantum information. A natural source of optical vortices is the interaction of light beams with matter vortices in liquid crystal cells. The rhythms that govern the emergence of matter vortices due to fluctuations are not established. Here, we investigate the nucleation mechanisms of the matter vortices in liquid crystal cells and establish statistical laws that govern them. Based on a stochastic amplitude equation, the law for the number of nucleated vortices as a function of anisotropy, voltage, and noise level intensity is set. Experimental observations in a nematic liquid crystal cell with homeotropic anchoring and a negative anisotropic dielectric constant under the influence of a transversal electric field show a qualitative agreement with the theoretical findings.","lang":"eng"}],"status":"public","date_updated":"2023-08-03T06:46:54Z"},{"oa":1,"_id":"13355","author":[{"first_name":"Richard H.","full_name":"Huang, Richard H.","last_name":"Huang"},{"last_name":"Nayeem","first_name":"Nazia","full_name":"Nayeem, Nazia"},{"last_name":"He","full_name":"He, Ye","first_name":"Ye"},{"last_name":"Morales","full_name":"Morales, Jorge","first_name":"Jorge"},{"full_name":"Graham, Duncan","first_name":"Duncan","last_name":"Graham"},{"full_name":"Klajn, Rafal","first_name":"Rafal","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","last_name":"Klajn"},{"last_name":"Contel","full_name":"Contel, Maria","first_name":"Maria"},{"last_name":"O'Brien","first_name":"Stephen","full_name":"O'Brien, Stephen"},{"last_name":"Ulijn","first_name":"Rein V.","full_name":"Ulijn, Rein V."}],"date_published":"2022-01-06T00:00:00Z","publisher":"Wiley","year":"2022","language":[{"iso":"eng"}],"doi":"10.1002/adma.202104962","type":"journal_article","quality_controlled":"1","publication_identifier":{"eissn":["1521-4095"],"issn":["0935-9648"]},"month":"01","article_type":"original","volume":34,"pmid":1,"article_number":"2104962","date_created":"2023-08-01T09:33:26Z","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"intvolume":"        34","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","abstract":[{"text":"Supramolecular self-assembly in biological systems holds promise to convert and amplify disease-specific signals to physical or mechanical signals that can direct cell fate. However, it remains challenging to design physiologically stable self-assembling systems that demonstrate tunable and predictable behavior. Here, the use of zwitterionic tetrapeptide modalities to direct nanoparticle assembly under physiological conditions is reported. The self-assembly of gold nanoparticles can be activated by enzymatic unveiling of surface-bound zwitterionic tetrapeptides through matrix metalloprotease-9 (MMP-9), which is overexpressed by cancer cells. This robust nanoparticle assembly is achieved by multivalent, self-complementary interactions of the zwitterionic tetrapeptides. In cancer cells that overexpress MMP-9, the nanoparticle assembly process occurs near the cell membrane and causes size-induced selection of cellular uptake mechanism, resulting in diminished cell growth. The enzyme responsiveness, and therefore, indirectly, the uptake route of the system can be programmed by customizing the peptide sequence: a simple inversion of the two amino acids at the cleavage site completely inactivates the enzyme responsiveness, self-assembly, and consequently changes the endocytic pathway. This robust self-complementary, zwitterionic peptide design demonstrates the use of enzyme-activated electrostatic side-chain patterns as powerful and customizable peptide modalities to program nanoparticle self-assembly and alter cellular response in biological context.","lang":"eng"}],"publication_status":"published","oa_version":"Published Version","day":"06","date_updated":"2023-08-07T09:58:17Z","status":"public","main_file_link":[{"url":"https://doi.org/10.1002/adma.202104962","open_access":"1"}],"external_id":{"pmid":["34668253"]},"title":"Self‐complementary zwitterionic peptides direct nanoparticle assembly and enable enzymatic selection of endocytic pathways","publication":"Advanced Materials","citation":{"short":"R.H.

The primary focus of the study is placed on the emergence of drifting–rotating waves (DRW) that capture, in a relatively small domain, the main features of coherent structures typically observed in developed turbulence. The transitional dynamics of the subcritical region, far below the first instability of the laminar circular Couette flow, is determined by the upper and lower branches of DRW solutions originated at saddle-node bifurcations. The mechanism whereby these solutions self-sustain, and the chaotic dynamics they induce, are conspicuously reminiscent of other subcritical shear flows. Remarkably, the flow properties of DRW persist even as the Reynolds number is increased beyond the linear stability threshold of the base flow. Simulations in a narrow parallelogram domain stretched in the azimuthal direction to revolve around the apparatus a full turn confirm that self-sustained vortices eventually concentrate into a localised pattern. The resulting statistical steady state satisfactorily reproduces qualitatively, and to a certain degree also quantitatively, the topology and properties of spiral turbulence as calculated in a large periodic domain of sufficient aspect ratio that is representative of the real system."}],"publication_status":"published","oa_version":"Preprint","day":"07","status":"public","date_updated":"2023-08-04T08:54:16Z","volume":951,"article_type":"original","isi":1,"quality_controlled":"1","publication_identifier":{"issn":["0022-1120"],"eissn":["1469-7645"]},"month":"11","keyword":["Mechanical Engineering","Mechanics of Materials","Condensed Matter Physics","Applied Mathematics"],"intvolume":"       951","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_processing_charge":"No","acknowledgement":"K.D.’s research was supported by an Australian Research Council Discovery Early Career\r\nResearcher Award (DE170100171).

We first explore the stability of all the steady flow solution families formerly identified by Ayats et al. [“Flows between orthogonally stretching parallel plates,” Phys. Fluids 33, 024103 (2021)], concluding that only the one that originates from the Stokesian approximation is actually stable. When both plates are shrinking at identical or nearly the same deceleration rates, this Stokesian flow exhibits a Hopf bifurcation that leads to stable time-periodic regimes. The resulting time-periodic orbits or flows are tracked for different Reynolds numbers and stretching rates while monitoring their Floquet exponents to identify secondary instabilities. It is found that these time-periodic flows also exhibit Neimark–Sacker bifurcations, generating stable quasiperiodic flows (tori) that may sometimes give rise to chaotic dynamics through a Ruelle–Takens–Newhouse scenario. However, chaotic dynamics is unusually observed, as the quasiperiodic flows generally become phase-locked through a resonance mechanism before a strange attractor may arise, thus restoring the time-periodicity of the flow. In this work, we have identified and tracked four different resonance regions, also known as Arnold tongues or horns. In particular, the 1 : 4 strong resonance region is explored in great detail, where the identified scenarios are in very good agreement with normal form theory.

Despite these clear experimental demonstrations, a complete theoretical and microscopic understanding of their magnetic anisotropy is still lacking. In particular, the validity limit of identifying their one-dimensional (1-D) Ising nature has remained uninvestigated in a quantitative way. Here we performed the complete mapping of magnetic anisotropy for a prototypical Ising vdW magnet FePS3 for the first time. Combining torque magnetometry measurements with their magnetostatic model analysis and the relativistic density functional total energy calculations, we successfully constructed the three-dimensional (3-D) mappings of the magnetic anisotropy in terms of magnetic torque and energy. The results not only quantitatively confirm that the easy axis is perpendicular to the ab plane, but also reveal the anisotropies within the ab, ac, and bc planes. Our approach can be applied to the detailed quantitative study of magnetism in vdW materials."}],"date_updated":"2021-12-01T10:36:56Z","status":"public","month":"04","publication_identifier":{"issn":["2053-1583"]},"quality_controlled":"1","volume":8,"article_type":"original","date_created":"2021-03-23T07:10:17Z","article_number":"035011","department":[{"_id":"KiMo"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","extern":"1","article_processing_charge":"No","intvolume":"         8","keyword":["Mechanical Engineering","General Materials Science","Mechanics of Materials","General Chemistry","Condensed Matter Physics"],"author":[{"full_name":"Nauman, Muhammad","first_name":"Muhammad","orcid":"0000-0002-2111-4846","id":"32c21954-2022-11eb-9d5f-af9f93c24e71","last_name":"Nauman"},{"last_name":"Kiem","first_name":"Do Hoon","full_name":"Kiem, Do Hoon"},{"last_name":"Lee","first_name":"Sungmin","full_name":"Lee, Sungmin"},{"first_name":"Suhan","full_name":"Son, Suhan","last_name":"Son"},{"first_name":"J-G","full_name":"Park, J-G","last_name":"Park"},{"full_name":"Kang, Woun","first_name":"Woun","last_name":"Kang"},{"first_name":"Myung Joon","full_name":"Han, Myung Joon","last_name":"Han"},{"full_name":"Jo, Youn Jung","first_name":"Youn Jung","last_name":"Jo"}],"_id":"9282","oa":1,"date_published":"2021-04-06T00:00:00Z","doi":"10.1088/2053-1583/abeed3","language":[{"iso":"eng"}],"year":"2021","publisher":"IOP Publishing","type":"journal_article"},{"ec_funded":1,"abstract":[{"text":"Solution synthesis of particles emerged as an alternative to prepare thermoelectric materials with less demanding processing conditions than conventional solid-state synthetic methods. However, solution synthesis generally involves the presence of additional molecules or ions belonging to the precursors or added to enable solubility and/or regulate nucleation and growth. These molecules or ions can end up in the particles as surface adsorbates and interfere in the material properties. This work demonstrates that ionic adsorbates, in particular Na⁺ ions, are electrostatically adsorbed in SnSe particles synthesized in water and play a crucial role not only in directing the material nano/microstructure but also in determining the transport properties of the consolidated material. In dense pellets prepared by sintering SnSe particles, Na remains within the crystal lattice as dopant, in dislocations, precipitates, and forming grain boundary complexions. These results highlight the importance of considering all the possible unintentional impurities to establish proper structure-property relationships and control material properties in solution-processed thermoelectric materials.","lang":"eng"}],"oa_version":"Published Version","publication_status":"published","day":"29","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)"},"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NanoFab"}],"status":"public","date_updated":"2023-08-14T07:25:27Z","external_id":{"pmid":["34626034"],"isi":["000709899300001"]},"related_material":{"record":[{"status":"public","id":"12885","relation":"dissertation_contains"}]},"file":[{"creator":"cchlebak","access_level":"open_access","relation":"main_file","content_type":"application/pdf","file_name":"2021_AdvancedMaterials_Liu.pdf","file_size":5595666,"date_created":"2022-02-03T13:16:14Z","checksum":"990bccc527c64d85cf1c97885110b5f4","file_id":"10720","date_updated":"2022-02-03T13:16:14Z","success":1}],"title":"The importance of surface adsorbates in solution‐processed thermoelectric materials: The case of SnSe","publication":"Advanced Materials","has_accepted_license":"1","issue":"52","scopus_import":"1","project":[{"name":"International IST Doctoral Program","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","grant_number":"665385","call_identifier":"H2020"},{"_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","grant_number":"754411"},{"grant_number":"M02889","_id":"9B8804FC-BA93-11EA-9121-9846C619BF3A","name":"Bottom-up Engineering for Thermoelectric Applications"},{"_id":"9B8F7476-BA93-11EA-9121-9846C619BF3A","name":"HighTE: The Werner Siemens Laboratory for the High Throughput Discovery of Semiconductors for Waste Heat Recovery"}],"citation":{"chicago":"Liu, Yu, Mariano Calcabrini, Yuan Yu, Aziz Genç, Cheng Chang, Tommaso Costanzo, Tobias Kleinhanns, et al. “The Importance of Surface Adsorbates in Solution‐processed Thermoelectric Materials: The Case of SnSe.” <i>Advanced Materials</i>.

Here, we demonstrate that a similar concept can be extended to the optics realm, particularly to propagating phonon polaritons–hybrid light-matter interactions. To do this, we fabricate stacks composed of two twisted slabs of a vdW crystal (α-MoO3) supporting anisotropic phonon polaritons (PhPs), and image the propagation of the latter when launched by localized sources. Our images reveal that, under a critical angle, the PhPs isofrequency curve undergoes a topological transition, in which the propagation of PhPs is strongly guided (canalization regime) along predetermined directions without geometric spreading. These results demonstrate a new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nanoimaging, (bio)-sensing, or heat management."}],"status":"public","date_updated":"2023-09-05T12:05:58Z"},{"related_material":{"record":[{"relation":"research_data","status":"deleted","id":"7151"},{"id":"7262","status":"public","relation":"part_of_dissertation"},{"status":"public","id":"8562","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","id":"1001","status":"public"},{"relation":"research_data","id":"8375","status":"public"}]},"file":[{"file_name":"thesis_rguseinov.pdf","file_size":70950442,"checksum":"f8da89553da36037296b0a80f14ebf50","date_created":"2020-09-10T16:11:49Z","file_id":"8367","date_updated":"2020-09-10T16:11:49Z","success":1,"creator":"rguseino","access_level":"open_access","relation":"main_file","content_type":"application/pdf"},{"file_size":76207597,"file_name":"thesis_source.zip","date_updated":"2020-09-16T15:11:01Z","checksum":"e8fd944c960c20e0e27e6548af69121d","file_id":"8374","date_created":"2020-09-11T09:39:48Z","creator":"rguseino","relation":"source_file","content_type":"application/x-zip-compressed","access_level":"closed"}],"title":"Computational design of curved thin shells: From glass façades to programmable matter","project":[{"grant_number":"715767","call_identifier":"H2020","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","_id":"24F9549A-B435-11E9-9278-68D0E5697425"}],"citation":{"ama":"Guseinov R.

Among their remarkable properties are, for example, aesthetics of organic shapes, ability to evenly distribute loads, or efficient flow separation. They find applications across vast length scales ranging from sky-scraper architecture to microscopic devices. But, at\r\nthe same time, the design of curved shells and their manufacturing process pose a variety of challenges. In this thesis, they are addressed from several perspectives. In particular, this thesis presents approaches based on the transformation of initially flat sheets into the target curved surfaces. This involves problems of interactive design of shells with nontrivial mechanical constraints, inverse design of complex structural materials, and data-driven modeling of delicate and time-dependent physical properties. At the same time, two newly-developed self-morphing mechanisms targeting flat-to-curved transformation are presented.\r\nIn architecture, doubly curved surfaces can be realized as cold bent glass panelizations. Originally flat glass panels are bent into frames and remain stressed. This is a cost-efficient fabrication approach compared to hot bending, when glass panels are shaped plastically. However such constructions are prone to breaking during bending, and it is highly\r\nnontrivial to navigate the design space, keeping the panels fabricable and aesthetically pleasing at the same time. We introduce an interactive design system for cold bent glass façades, while previously even offline optimization for such scenarios has not been sufficiently developed. Our method is based on a deep learning approach providing quick\r\nand high precision estimation of glass panel shape and stress while handling the shape\r\nmultimodality.\r\nFabrication of smaller objects of scales below 1 m, can also greatly benefit from shaping originally flat sheets. In this respect, we designed new self-morphing shell mechanisms transforming from an initial flat state to a doubly curved state with high precision and detail. Our so-called CurveUps demonstrate the encodement of the geometric information\r\ninto the shell. Furthermore, we explored the frontiers of programmable materials and showed how temporal information can additionally be encoded into a flat shell. This allows prescribing deformation sequences for doubly curved surfaces and, thus, facilitates self-collision avoidance enabling complex shapes and functionalities otherwise impossible.\r\nBoth of these methods include inverse design tools keeping the user in the design loop."}],"date_updated":"2024-02-21T12:44:29Z","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"ScienComp"}],"status":"public","month":"09","publication_identifier":{"isbn":["978-3-99078-010-7"],"issn":["2663-337X"]},"supervisor":[{"orcid":"0000-0001-6511-9385","last_name":"Bickel","id":"49876194-F248-11E8-B48F-1D18A9856A87","full_name":"Bickel, Bernd","first_name":"Bernd"}],"date_created":"2020-09-10T16:19:55Z","department":[{"_id":"BeBi"}],"acknowledgement":"During the work on this thesis, I received substantial support from IST Austria’s scientific service units.

However, most proposed solutions evolve towards a target geometry without considering time-dependent actuation paths. To achieve more complex geometries and avoid self-collisions, it is critical to encode a spatial and temporal shape evolution within the initially flat shell. Recent realizations of time-dependent morphing are limited to the actuation of few, discrete hinges and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding temporal shape evolution in architected shells that assume complex shapes and doubly curved geometries. The shells are non-periodic tessellations of pre-stressed contractile unit cells that soften in water at rates prescribed locally by mesostructure geometry. The ensuing midplane contraction is coupled to the formation of encoded curvatures.

Here, we report a general methodology allowing for reversible switching of such molecules on the surfaces of solid materials. Our method is based on dispersing photochromic compounds within polysilsesquioxane nanowire networks (PNNs), which can be fabricated as transparent, highly porous, micrometer-thick layers on various substrates. We found that azobenzene switching within the PNNs proceeded unusually fast compared with the same molecules in liquid solvents. Efficient isomerization of another photochromic system, spiropyran, from a colorless to a colored form was used to create reversible images in PNN-coated glass. The coloration reaction could be induced with sunlight and is of interest for developing “smart” windows.","lang":"eng"}],"page":"7106-7111","oa_version":"None","publication_status":"published","day":"20","date_updated":"2023-08-07T10:39:34Z","status":"public","quality_controlled":"1","publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"month":"09","volume":19,"article_type":"original","pmid":1,"date_created":"2023-08-01T09:38:23Z","keyword":["Mechanical Engineering","Condensed Matter Physics","General Materials Science","General Chemistry","Bioengineering"],"intvolume":"        19","article_processing_charge":"No","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"13370","author":[{"full_name":"Chu, Zonglin","first_name":"Zonglin","last_name":"Chu"},{"last_name":"Klajn","id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","full_name":"Klajn, Rafal","first_name":"Rafal"}],"date_published":"2019-09-20T00:00:00Z","publisher":"American Chemical Society","year":"2019","language":[{"iso":"eng"}],"doi":"10.1021/acs.nanolett.9b02642","type":"journal_article"},{"date_published":"2019-06-27T00:00:00Z","_id":"10622","oa":1,"author":[{"orcid":"0000-0001-8223-8896","id":"edfc7cb1-526e-11ec-b05a-e6ecc27e4e48","last_name":"Polshyn","first_name":"Hryhoriy","full_name":"Polshyn, Hryhoriy"},{"last_name":"Naibert","first_name":"Tyler","full_name":"Naibert, Tyler"},{"last_name":"Budakian","full_name":"Budakian, Raffi","first_name":"Raffi"}],"type":"journal_article","year":"2019","publisher":"American Chemical Society","doi":"10.1021/acs.nanolett.9b01983","language":[{"iso":"eng"}],"article_type":"original","volume":19,"publication_identifier":{"issn":["1530-6984"],"eissn":["1530-6992"]},"quality_controlled":"1","month":"06","intvolume":"        19","keyword":["mechanical engineering","condensed matter physics","general materials science","general chemistry","bioengineering"],"user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","extern":"1","article_processing_charge":"No","acknowledgement":"We are grateful to Nadya Mason, Taylor Hughes, and Alexey Bezryadin for useful discussions.

A micron-size magnetic particle attached to the tip of a silicon cantilever is used to locally apply magnetic flux through the superconducting structure. By scanning the tip over the surface of the device and by utilizing the dynamical coupling between the vortices and the cantilever, a high-resolution spatial map of the different vortex configurations is obtained. Moving the tip to a particular location in the map stabilizes a distinct multivortex configuration. Thus, the scanning of the tip over a particular trajectory in space permits nontrivial operations to be performed, such as braiding of individual vortices within a larger vortex ensemble—a key capability required by many proposals for topological quantum computing."}],"day":"27","page":"5476-5482","publication_status":"published","oa_version":"Preprint","status":"public","date_updated":"2022-01-13T15:41:24Z","title":"Manipulating multivortex states in superconducting structures","external_id":{"pmid":["31246034"],"arxiv":["1905.06303"]},"publication":"Nano Letters","main_file_link":[{"url":"https://arxiv.org/abs/1905.06303","open_access":"1"}],"scopus_import":"1","issue":"8","arxiv":1,"citation":{"chicago":"Polshyn, Hryhoriy, Tyler Naibert, and Raffi Budakian. “Manipulating Multivortex States in Superconducting Structures.” <i>Nano Letters</i>.

Although this mode of self-assembly is ubiquitous in nature, where it gives rise to functions such as signal processing, motility, self-healing, self-replication, and ultimately life, examples of dissipative self-assembly processes in man-made systems are few and far between. Herein, recent progress in developing diverse synthetic dissipative self-assembly systems is discussed. The systems reported thus far can be categorized into three classes, in which: i) the fuel chemically modifies the building blocks, thus triggering their self-assembly, ii) the fuel acts as a template interacting with the building blocks noncovalently, and iii) transient states are induced by the addition of two mutually exclusive stimuli. These early studies give rise to materials that would be difficult to obtain otherwise, including hydrogels with programmable lifetimes, vesicular nanoreactors, and membranes exhibiting transient conductivity.","lang":"eng"}],"publication_status":"published","oa_version":"None","day":"11","date_updated":"2023-08-07T10:56:26Z","status":"public","quality_controlled":"1","publication_identifier":{"issn":["0935-9648"],"eissn":["1521-4095"]},"month":"10","volume":30,"article_type":"original","pmid":1,"date_created":"2023-08-01T09:39:46Z","article_number":"1706750","keyword":["Mechanical Engineering","Mechanics of Materials","General Materials Science"],"intvolume":"        30","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","extern":"1","_id":"13375","author":[{"full_name":"De, Soumen","first_name":"Soumen","last_name":"De"},{"id":"8e84690e-1e48-11ed-a02b-a1e6fb8bb53b","last_name":"Klajn","first_name":"Rafal","full_name":"Klajn, Rafal"}],"date_published":"2018-10-11T00:00:00Z","publisher":"Wiley","year":"2018","language":[{"iso":"eng"}],"doi":"10.1002/adma.201706750","type":"journal_article"}]
