Scope Materials and Environmental studies are multidisciplinary of Material and Environmental science of all academic fields. Material science concern the cycle from production, application to the deterioration by environmental factors. It is a natural cycle, but accelerated processes. These phenomena involve qualitative and quantitative estimations and take wide parts of the environment. These concepts rely on preserve our environment. The use of materials means degradation in the application environment. This degradation is a spontaneous return but more or less accelerated by the circumstances. View the huge quantities of materials used, it must act quickly and effectively to preserve the environmental burden of products.

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.
