Befehl \cite funktioniert nicht

Ich habe es biblatexohne große Probleme verwendet. Aber als ich es verwenden wollte \cite, erschien plötzlich keine Bibliographiequelle. Hier ist ein MWE:

 \documentclass[a4paper,openright,10pt]{book}
 \usepackage[utf8]{inputenc}
 \usepackage[spanish, es-tabla]{babel}
 \usepackage{setspace}
 \usepackage[backend=bibtex,style=chem-angew,citestyle=numeric-comp]{biblatex}
 \addbibresource{biblio} 
\usepackage{csquotes}
\usepackage{titlesec}
 \usepackage{tocloft}
  \begin{document}
 \cite{debabrata_bhadra_synthesis_2011} % this reference actually does EXIST
  \end{document}

Und dann kopiere ich die Referenz:

   @article{debabrata_bhadra_synthesis_2011,
title = {Synthesis of {PVDF}/{BiFeO}3 Nanocomposite and Observation of Enhanced Electrical Conductivity and Low-Loss Dielectric Permittivity at Percolation Threshold},
volume = {50},
doi = {10.1002/polb.23041},
pages = {572--579},
journaltitle = {{JOURNAL} {OF} {POLYMER} {SCIENCE} {PART} B: {POLYMER} {PHYSICS}},
shortjournal = {J. Polym. Sci., Part B: Polym. Phys.},
author = {{Debabrata Bhadra} and {Md. G. Masud} and {S. Sarkar} and {J. Sannigrahi} and {S. K. De} and {B. K. Chaudhuri}},
date = {2011-11-21},
file = {PVDF  BiFeO3 intro OK.pdf:C\:\\Users\\L-COM\\AppData\\Roaming\\Zotero\\Zotero\\Profiles\\wvijlgbz.default\\zotero\\storage\\I7SAEGPC\\PVDF  BiFeO3 intro OK.pdf:application/pdf}
}

Dies passiert bei allen Referenzen, die ich in der Bibliographie habe. Hier ist der Fehlerbericht:

   Please (re)run BibTeX on the file(s):(biblatex) tesis(biblatex) and rerun           LaTeX afterwards.

Vielen Dank!

Einige Vorschläge:

  • Fügen Sie die Anweisung hinzu \printbibliography, wo die Bibliographie gedruckt werden soll

  • ändern\addbibresource{biblio}​\addbibresource{biblio.bib}

  • Entfernen Sie die inneren geschweiften Klammern aus den Feldern authorundjournaltitle

  • Denken Sie daran, BibTeX und dann LaTeX noch zweimal auszuführen.

Mit diesen Änderungen sollte die Ein-Element-Bibliographie folgendermaßen aussehen:

Bildbeschreibung hier eingeben

\RequirePackage{filecontents}
\begin{filecontents}{biblio.bib}
@article{debabrata_bhadra_synthesis_2011,
title = {Synthesis of {PVDF}/{BiFeO}3 Nanocomposite and Observation of Enhanced Electrical Conductivity and Low-Loss Dielectric Permittivity at Percolation Threshold},
volume = {50},
doi = {10.1002/polb.23041},
pages = {572--579},
journaltitle = {JOURNAL OF POLYMER SCIENCE PART B: POLYMER PHYSICS},
shortjournal = {J. Polym. Sci., Part B: Polym. Phys.},
author = {Debabrata Bhadra and Md. G. Masud and S. Sarkar and J. Sannigrahi and S. K. De and B. K. Chaudhuri},

}
