    • A new approach to the internal sizing of paper via biotechnological processes 

      García Ubasart, Jordi; Roncero Vivero, María Blanca; Vidal Lluciá, Teresa (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work deals with the study of a new biotechnological procedure, employing laccase in combination with hydrophobic compounds, for the biomodification of fibres and the internal sizing of paper. Cellulose fibres from ...

    • Effect of the laccase mediator system on the fibre properties of TCF bleached kraft pulp 

      Cadena Chamorro, Edith Marleny; Cusola Aumedes, Oriol; Vidal Lluciá, Teresa; Torres López, Antonio Luis (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The application of the laccase mediator system (L stage) to TCF bleached pulp from Eucalyptus globulus with a low residual lignin content provides useful information about its effect in the hexenuronic acids content, ...

    • Bleached dissolving pulps applying laccase treatments 

      Quintana, Elisabet; Valls Vidal, Cristina; Roncero Vivero, María Blanca (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A biobleaching sequence, using a laccase enzyme (Trametes Villosa) in combination with different mediators, was applied to softwood dissolving cellulose in order to study its bleaching efficiency and its potential in terms ...

    • Laccase-TEMPO oxidation of sisal pulp for improving paper strength properties: influence of the operating conditions 

      Aracri, Elisabetta; Valls Vidal, Cristina; Vidal Lluciá, Teresa (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The oxidation of a low lignin content sisal pulp by laccase-TEMPO system has been investigated and evaluated as potential approach for improving the paper strength properties. TEMPO mediated oxidation was found to cause ...

    • Nanofibrillated cellulose as reinforcement for high performance cement mortar composites 

      Ardanuy Raso, Mònica; Claramunt Blanes, Josep; Parés Sabatés, Ferran; Aracri, Elisabetta; Vidal Lluciá, Teresa (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this work, the preparation and characterization of new cement mortars reinforced with nanofibrillated cellulose fibres has been carried out. The effect of the fibre fibrillation degree on the mechanical performance of ...

    • Paper functionalization by means of enzymatic surface treatments using hydrophobic compounds and lignosulfonates 

      Cusola Aumedes, Oriol; García Ubasart, Jordi; Valls Vidal, Cristina; Vidal Lluciá, Teresa; Roncero Vivero, María Blanca (2012)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In the present work an innovative method for achieving enzymatic surface functionalization on finished paper sheets is presented. A commercial filter paper was surface sized with laccase derived from Trametes Villosa, ...
