JOURNAL METRICS

Impact Factor (JCR) 2022: 0.9 ℹImpact Factor (JCR):

The JCR provides quantitative tools for ranking, evaluating, categorizing, and comparing journals. The impact factor is one of these; it is a measure of the frequency with which the “average article” in a journal has been cited in a particular year or period. The annual JCR impact factor is a ratio between citations and recent citable items published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.

5-Year Impact Factor: 0.7 ℹ5-Year Impact Factor:

A 5-Year Impact Factor shows the long-term citation trend for a journal. This is calculated differently from the Journal Impact Factor, so it is not simply an average of the Impact Factors in the time period. The Impact Factor itself is based only on Web of Science Core Collection citation data from the last three years and thus reflects only recent impact. The Journal Impact Factor is the average number of times articles from the journal published in the past two years have been cited in the Journal Citation Reports year.

CiteScore 2022: 1.9 ℹCiteScore:

CiteScore is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.

SCImago Journal Rank (SJR) 2022: 0.21 ℹSCImago Journal Rank (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.

Source Normalized Impact per Paper (SNIP) 2022: 0.296 ℹSource Normalized Impact per Paper (SNIP):

SNIP measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields. SNIP takes into account characteristics of the source's subject field, which is the set of documents citing that source.

OPEN ACCESS

Abstract:

In this research, nanocomposite membranes were prepared using polyethylene oxide as polymer host, lithium bis(trifluoromethanesulfonyl imide) as salt and nanochitosan as inert filler. Initially nanochitosan was prepared from chitosan by ionotropic gelation method. Nanocomposite membranes were prepared by solvent free membrane hot press technique. The prepared membranes possessed excellent physico-chemical properties. The complexing behavior and structural reorganization in polymer electrolytes were analyzed by XRD and FT-IR analyzes. The decrease in crystalline nature of polymer electrolytes was confirmed by DSC analysis. The electrolyte S3 possessed high conductivity and attained a maximum of 10^-3.01S/cm.
