In this work, the structures of the as-synthesized, calcined and dealuminated YNU-5 zeolites, were investigated by various techniques with special emphasis on advanced electron microscopy methods. The frameworks of the three materials were solely determined by three-dimension electron diffraction tomography, and the space group for the three of them was determined to be Cmmm, which is of higher symmetry than the previous reported result. Rietveld refinement was performed against synchrotron Powder X-ray diffraction data in order to obtain precise information of the framework and to locate the organic species, cations and water. Additionally, spherical aberration-corrected scanning transmission electron microscopy was employed to study the local fine structure and to indicate surface reconstruction associated to the displacement of the vacancies through the dealumination process. Finally, a minor phase, whose structure was solved by electron microscopy was found to be MSE framework type, appeared in all the three YNU-5 materials. Overall, the electron microscopy analyses reported in the present work provide additional information regarding the YNU-5 structure in terms of space group determination, additional surface terminations and the identification of a minor phase. 000151311 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E13-20R$$9info:eu-repo/grantAgreement/ES/MCIU/RYC-2018-024561-I 000151311 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 000151311 590__ $$a5.876$$b2021 000151311 591__ $$aCHEMISTRY, APPLIED$$b15 / 72 = 0.208$$c2021$$dQ1$$eT1 000151311 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b106 / 344 = 0.308$$c2021$$dQ2$$eT1 000151311 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b51 / 108 = 0.472$$c2021$$dQ2$$eT2 000151311 591__ $$aCHEMISTRY, PHYSICAL$$b58 / 165 = 0.352$$c2021$$dQ2$$eT2 000151311 592__ $$a0.924$$b2021 000151311 593__ $$aChemistry (miscellaneous)$$c2021$$dQ1 000151311 593__ $$aNanoscience and Nanotechnology$$c2021$$dQ1 000151311 593__ $$aMechanics of Materials$$c2021$$dQ1 000151311 593__ $$aCondensed Matter Physics$$c2021$$dQ1 000151311 594__ $$a8.9$$b2021 000151311 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000151311 700__ $$aZhou, Y. 000151311 700__ $$aSun, T. 000151311 700__ $$aChen, P. 000151311 700__ $$aLi, C. 000151311 700__ $$aKubota, Y. 000151311 700__ $$aInagaki, S. 000151311 700__ $$aDejoie, C. 000151311 700__ $$0(orcid)0000-0002-5229-2717$$aMayoral, A.$$uUniversidad de Zaragoza 000151311 700__ $$aTerasaki, O. 000151311 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
