Nanotechnology

Nanotechnology aims to publish original research at the forefront of nanoscale science and technology across all disciplines. The journal's scope encompasses the study of both fundamental phenomena at the nanoscale and applications of these phenomena. 'Nanotechnology' is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. To be publishable in the journal, articles must meet the highest scientific quality standards, contain significant and original new science, and make substantial advances in nanoscale science and technology. Research on the synthesis of materials should contain a significant innovation either in methodology, materials or demonstrated application. To ensure high editorial standards, every submitted article is initially assessed by the editors of the journal before being sent to independent referees. Articles can be rejected without refereeing after this initial assessment by the editors. Due to the high volume of papers that we receive, we regret that we are unable to provide feedback on individual articles. Authors appealing against the decision will have to demonstrate to the Editorial Board of the journal at nano@iop.org that their paper contains significant new science of high quality and interest.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.

Evolution of the number of total citation per document and external citation per document (i.e. journal self-citations removed) received by a journal's published documents during the three previous years. External citations are calculated by subtracting the number of self-citations from the total number of citations received by the journal’s documents.

Citable documents

Non-citable documents

Not every article in a journal is considered primary research and therefore "citable", this chart shows the ratio of a journal's articles including substantial research (research articles, conference papers and reviews) in three year windows vs. those documents other than research articles, reviews and conference papers.
