This technique is based on the analysis of EPR spectra of a membrane containing stable radicals sorbed on oxidized graphene planes. The efficiency of the method depends on the spin probe structure; therefore, it is important to find stable paramagnetic substances that are most sensitive to the alignment of graphene oxide membranes. In the present work, three novel stable nitroxide radicals containing aromatic fragments with two nitrogen atoms were tested as spin probes to study graphene oxide membranes. The spin-Hamiltonian parameters of the radicals in graphite oxide powder and orientational order parameters of the probes inside graphene oxide membrane were determined. The sensitivity of one of these radicals to membrane orientational ordering was found to be higher than for any of spin probes used previously. A likely reason for this higher sensitivity is the presence of heteroatoms which can facilitate interaction between paramagnetic molecules and oxygen-containing groups on the inner surface of the membrane. The new high-sensitivity spin probe may significantly increase the potential of EPR spectroscopy for studying the internal structure of graphene oxide membranes. 2023 true true true false true false GOLD 2026-10-23 true https://doi.org/10.3390/membranes12121241 4 0 4 1 1 4 4 4 4 4 4 1 1 1 3 0 4 1 4 1 0 3 3 Folyóiratcikk Journal Article 24 4 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2023 0 2 1 2 1 2024 0 1 0 1 0 2025 0 1 0 1 0 Q2 false false false false 2023-01-05T06:01:04.942+0000 Szerves és Gyógyszerkémiai Intézet (PTE / GYTK) 2 11 1 5 0 true Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 106196600 /api/authorship/106196600 1 0.2 true false true Chumakova Natalia A true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 106196601 /api/authorship/106196601 2 0.2 false false false Author 10002595 /api/author/10002595 Kálai Tamás true 10002595 true Kalai Tamas true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 106196602 /api/authorship/106196602 3 0.2 false false false Rebrikova Anastasiya T true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 106196603 /api/authorship/106196603 4 0.2 false false false Author 10006127 /api/author/10006127 Pápayné Sár Cecília true 10006127 true Sár Cecília true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 106196604 /api/authorship/106196604 5 0.2 false true false Kokorin Alexander I true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PublicationIdentifier 22796427 /api/publicationidentifier/22796427 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.3390/membranes12121241 https://doi.org/10.3390/membranes12121241 false true PublicationIdentifier 22869555 /api/publicationidentifier/22869555 PlainSource 1 /api/publicationsource/1 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 000902988700001 https://www.webofscience.com/wos/woscc/full-record/000902988700001 false true PublicationIdentifier 22796456 /api/publicationidentifier/22796456 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85144622959 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85144622959 false true PublicationIdentifier 22796426 /api/publicationidentifier/22796426 PlainSource 17 /api/publicationsource/17 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true PubMed PubMed http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=@@@&dopt=Abstract true true 17 true IDENTICAL 36557148 http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=36557148&dopt=Abstract false true Keyword 1645048 /api/keyword/1645048 true true Keyword 2044132 /api/keyword/2044132 true true Keyword 2955194 /api/keyword/2955194 true true SjrRating 11288333 /api/sjrrating/11288333 117 0.49 journal RatingType 10002 /api/ratingtype/10002 sjr true true ClassificationExternal 1501 /api/classificationexternal/1501 true 1501 true Q2 DIRECT true true /api/publication/33543495 <div class="JournalArticle Publication long-list"> <div class="authors"> <img title="Forrásközlemény" style="float: left" src="/frontend/resources/grid/publication-core-icon.png"> <img title="Idézőközlemény" style="float: left" src="/frontend/resources/grid/publication-citation-icon.png"> <div class="autype autype0"> <span class="author-name" >Chumakova Natalia A ✉ </span> ;&nbsp;&nbsp;&nbsp;
