Tehran – In 2024, with a total of 4,615 articles published in the top 25% of the journal (Q1 Journals), Iran is placed in the top 10 countries when publishing nanotechnology articles and ranks 12 in the H index of the world’s nanoarticles.
With 86,924, 14,473 and 11,194 articles, China, the US and India are the top three countries. Iran is ranked in England (4,360), Japan (4,022) and Spain (3,830), reports ISNA.
Q1 Journal Index is used to classify scientific journals based on their impact. It is most commonly used in databases such as Scimago Journal Rank (SJR) and Journal Citation Reports (JCR).
Rankings for the Q1 Journal are based on impact factors, SJR, H index, and number of citations, ISNA reports.
Introduced by physicist Jorge Hirsch, the H-Index is an important indicator for measuring the scientific impact of a researcher, journal or university. It was introduced by physicist Jorge Hirsch. Measure the number of scientific publications (many articles), scientific impact (number of citations), and the combination of research volume and quality.
Since 2011, the country has been suffering a downward trend with obtaining patents for nanotechnology, but has been placed in the top 30 countries in nanotechnology patented technology, ranked 27th in 2024.
It is noteworthy that the proportion of granted patents has increased from 19% in 2023 to 25% in 2024. Similarly, the number of published and granted patents increased slightly from 17% in 2023 to 19% in 2024.
By the end of 2024, Iran had announced 364 nanotechnology patents at the US Patent and Trademark Office (USPTO). 25% of Iran’s USPTO registered patents fall under the Nanotechnology category.
The most cited Iranian journal of nanotechnology in the world
The Journal Citation Report (JCR) Impact Factor 2024 cited 161 Iranian journals, giving them five names in the most cited world in the nanotechnology sector.
The Journal of Nanostructure in Chemistry (JNSC) is a member of Islamic AZAD University with an impact coefficient of 7.9. It is featured in the top 25% of JCR journals published by Clarivate Analytics in three categories, including Nanoscience and Nanotechnology, and ranks 34 among the 147 top journals. Chemistry, interdisciplinary, ranking 41 among 239 journals. Interdisciplinary Material Science, ranked 88 among the top journals of 460.
The journals of international nanoletters belonging to Kermanshah Islamic Azad University, Nanomedicine Journals belonging to Mashhad Medical Science University, Nanostructure Journals belonging to Kashan University, and Nanomedicine Journals belonging to the International Journals of NanoDimensions belonging to Tonkabon Islamic Azada University are 4.0, 1.7, 1.7, 1.3, and 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3, 1.3,
So far, 10 of the 12 specialized nanotechnology journals in the country have been indexed in international Scopus databases, five of which have received an impact factor.
JCR 2024 included data from over 21,000 journals from 113 countries in 254 research categories.
JCR is a database that provides influential factors and rankings for academic journals in the science, technology and social sciences, most commonly based on citation data. JCR is a widely used resource for evaluating and comparing journals within the research community.
The most well-known metric provided by JCR is the Journal Impact Factor (JIF). JIF is a measure of the frequency at which articles published in a particular journal are cited in a particular year.
JCR data is drawn from the Web of Science Core Collection, a comprehensive citation index.
Only journals that meet strict quality standards for inclusion in the Web of Science Core Collection are featured in the Journal Citation Report.
The annual report provides a rich array of publisher neutral data, metrics and analyses to enhance user understanding of journal performance, including widely recognized JIF and journal citation indicators.
