As SIGMA, we encourage the authors to use Mendeley as a reference management software. You can download Mendeley from the website freely. It is easy to learn from the videos and tutorials. After plug-ins in MS Word, authors need to select "Journal of Thermal Engineering" or "Energy" as a citation style. Mendeley manages your citations and bibliographies formatted in the journal's style.
