I'm trying to include a citation in a beamer frame following the instruction here. However, I couldn't figure out how to place them inside a subfigure environment. Namely, my code:

begin{frame}

  frametitle{Reactive-transport systems}

  begin{figure}

    centering

    begin{subfigure}{0.45textwidth}

      includegraphics[width=0.45textwidth]{Chabanon2017.jpg}

      caption{Here is text footfullcite{Chabanon2017}}

    end{subfigure}

    begin{subfigure}{0.45textwidth}

      includegraphics[width=0.45textwidth]{Steefel2005.jpg}

      caption{Here is text footfullcite{Steefel2005}}

    end{subfigure}

  end{figure}

end{frame}

And this is what I'm seeing:

Any suggestions on how to go around it?

EDIT: Add minimal working example:

documentclass{beamer}



usepackage{pgf}

usepackage{xcolor}

usepackage[utf8]{inputenc}

% Citation                                                                                                                      

usepackage[backend=bibtex, style=science]{biblatex}



usepackage{subcaption}

usepackage{filecontents}



begin{filecontents}{vorlage.bib}



 @article{test1,

    author  = {Shen Lin and Brian W. Kernighan},

    title   = {An Effective Heuristic Algorithm for the Travelling-Salesman Problem},

    journal = {Operations Research},

    volume  = {21},

    year    = {1973},

    pages   = {498--516},

 }



@BOOK{test,

  title = {The Infamous Test},

  publisher = {Testington Test},

  year = {2007},

  author = {John Doe},

  address = {Testville},

}



@ARTICLE{test2,

  author = {Testi, T.},

  year = {2003},

  title = {Testartikel},

  journal = {Testjournal}

}

end{filecontents}

begin{subfigure}{.45textwidth}

  centering

  includegraphics[width=linewidth]{example-image}

  label{fig:sub1}

end{subfigure}%

begin{subfigure}{.45textwidth}

  centering

  includegraphics[width=linewidth]{example-image}

  caption{A subfigure footfullcite{test1}}

  label{fig:sub2}

end{subfigure}

caption{A figure with two subfigures footfullcite{test2}}

label{fig:test}

end{figure}

end{frame}



end{document}

This will produce the following result:

and you can see that the citation is stuck underneath each subfigure instead of gathering all at the bottom of the page.

Based on Footfullcitetext and beamer: incremental numbering you could work around the problem like this:

documentclass{beamer}



%usepackage{pgf}

%usepackage{xcolor}

usepackage[utf8]{inputenc}

usepackage[style=science]{biblatex}

    year    = {1973},

 }

end{filecontents}

An alternative to @samcarter's since I done it before see the answer:

PS: The output is the same but I just used the footnotemark[] trick and let the footfullcite commands to be expanded inside an sbox (but actually outside of it). The good part is that no need of advanced bib(La)TeX knowledge is needed...
