[Tex/LaTex] Elsarticle abbreviations footnote before other frontmatter footnotes

elsarticlefootnotesfront-matter

In Elsevier articles, the abbreviations are presented as a footnote that appears at the bottom of the first page, before any other footnote related to the title or the authors.It has no footnote mark.

My problem is the following: If I put my abbreviations in the frontmatter, I get a blank page with my abbreviations footnote, before the first page. If I put it after the front matter, or inside one of the fields, than it gets after the author footnotes.
Code:

\documentclass[preprint,12pt,authoryear]{elsarticle}
%% abbreviations command (footnote without a footnote mark)
\newcommand{\abbreviations}[1]{%
  \begingroup\def\thefootnote{}\footnotetext{\textit{Abbreviations:}#1}\endgroup}
\begin{document}
\begin{frontmatter}
\title{Title}
%\abbreviations{S1, symbol1; S2, symbol2.}
\author{Author 1}
\author{Author 2\corref{cor1}}
\ead{name@adress.mail}
\cortext[cor1]{Corresponding author.}
\end{frontmatter}
\abbreviations{S1, symbol1; S2, symbol2.}
\end{document}
\endinput

Output:
output for elsarticle

Best Answer

elsarticle provides the command \nonumnote that puts an unnumbered footnote on the first page. Using this you can code your \abbreviations as 

\newcommand{\abbreviations}[1]{%
  \nonumnote{\textit{Abbreviations:\enspace}#1}}

and use it within frontmatter. nonumnotes are printed before curnotes, but after tnotes.

Sample output

\documentclass[preprint,12pt]{elsarticle}

\newcommand{\abbreviations}[1]{%
  \nonumnote{\textit{Abbreviations:\enspace}#1}}
