La0.5Ca0.5MO3 (M = Ni, Co, or Mn) was synthesized via sol-gel method. X-ray diffraction analysis revealed that the perovskite crystal structure possesses characteristic sharp and crystalline peaks for all synthesized ternary electrocatalysts. The average particle size calculated using Debye–Scherrer equation was in the order of La0.5Ca0.5NiO3 (LCNO) > La0.5Ca0.5CoO3 (LCCO)> La0.5Ca0.5MnO3 (LCMO). The elemental composition of as prepared sample, LCCO was investigated via x-ray fluorescence spectroscopy. The qualitative and quantitative analysis revealed the presence of La, Ca and Co in parent crystal structure with percentage compositions of 9.0, 3.12 and 87.82% respectively. The particle size distribution was homogenous, as determined by scanning electron and transmission electron microscopes. The electrocatalytic activity of the synthesized ternary electrocatalysts was studied electrochemically by cyclic voltammetry. The calculated diffusion coefficient values showed that electrode surface of LCNO and LCCO have limited efficiency for diffusion related phenomenon. The heterogeneous rate constants inferred better electrode kinetics of LCCO and LCNO which exhibited good electrocatalytic behavior; sharp anodic peaks were observed in the potential range of +0.3 to 0.6 V and +0.6 to 0.8 V, respectively. Methanol electro-oxidation was found minimal in case of LCMO sample. We have observed that Co substitution at B-site of perovskite electrode materials attains better electrochemical properties, thus in relation with reported literature."}],"oa_version":"None","publisher":"IOP Publishing","quality_controlled":"1","month":"01","intvolume":" 6","citation":{"ista":"Hussain T, Nauman M, Sabahat S, Arif S. 2020.

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. We propose an inverse design tool based on a data-driven model for unit cells’ temporal responses.","lang":"eng"}],"oa_version":"Published Version","ec_funded":1,"volume":11,"related_material":{"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/geometry-meets-time/","description":"News on IST Homepage"}],"record":[{"relation":"dissertation_contains","status":"public","id":"8366"},{"relation":"research_data","status":"public","id":"7154"}]},"publication_status":"published","publication_identifier":{"issn":["2041-1723"]},"language":[{"iso":"eng"}],"file":[{"file_id":"7336","checksum":"7db23fef2f4cda712f17f1004116ddff","content_type":"application/pdf","access_level":"open_access","relation":"main_file","date_created":"2020-01-15T14:35:34Z","file_name":"2020_NatureComm_Guseinov.pdf","date_updated":"2020-07-14T12:47:55Z","file_size":1315270,"creator":"rguseino"}],"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)"},"article_type":"original","type":"journal_article","keyword":["Design","Synthesis and processing","Mechanical engineering","Polymers"],"status":"public","_id":"7262","department":[{"_id":"BeBi"}],"file_date_updated":"2020-07-14T12:47:55Z","date_updated":"2024-02-21T12:45:02Z","ddc":["000"]},{"pmid":1,"oa_version":"Published Version","intvolume":" 39","month":"01","main_file_link":[{"url":"https://doi.org/10.1002/marc.201700827","open_access":"1"}],"scopus_import":"1","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["1022-1336"],"eissn":["1521-3927"]},"volume":39,"issue":"1","_id":"13379","keyword":["Materials Chemistry","Polymers and Plastics","Organic Chemistry"],"status":"public","type":"journal_article","article_type":"letter_note","extern":"1","date_updated":"2023-08-07T11:16:49Z","oa":1,"publisher":"Wiley","quality_controlled":"1","publication":"Macromolecular Rapid Communications","day":"08","year":"2018","date_created":"2023-08-01T09:40:48Z","date_published":"2018-01-08T00:00:00Z","doi":"10.1002/marc.201700827","article_number":"1700827","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"mla":"Bléger, David, and Rafal Klajn. “Integrating Macromolecules with Molecular Switches.” Macromolecular Rapid Communications, vol. 39, no. 1, 1700827, Wiley, 2018, doi:10.1002/marc.201700827.","apa":"Bléger, D., & Klajn, R.
