How to publish in this journal

Scope

Free Radical Biology and Medicine is the premier forum for publishing groundbreaking research in the redox biology of both health and disease. We focus on signal transduction and redox signaling; oxidative stress; reductive stress; redox stress; nitrosative stress; aging and age-related diseases; metabolic regulation and metabolic diseases; mitochondrial function and signaling; homeostatic mechanisms and adaptive responses; redox chemistry and mechanisms; materials & nanomaterials; non-thermal plasmas; microorganisms, fungi, plants, insects, animals, and humans; and antioxidant enzymes, pathways, and networks. We welcome both full-length and short Research Communications, Hypothesis Papers, Reviews, Mini Reviews, Graphical Reviews, and Critical Methods Papers. Free Radical Biology and Medicine also commissions themed Special Issues aimed at highlighting recent advances in both basic and clinical fields, with a particular focus on mechanisms underlying altered metabolism and redox signaling.

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.

Cites per Doc

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.
