    • Cooperative action of KIF1A Brownian motors with finite dwell time 

      Oriola Santandreu, David; Casademunt Viader, Jaume (2014-03-31)
      Article
      Accés obert
      We study in detail the cooperative action of small groups of KIF1A motors in its monomeric (single-headed) form within an arrangement relevant to vesicle traffic or membrane tube extraction. It has been recently shown that ...

    • Cooperative Force Generation of KIF1A Brownian Motors 

      Oriola Santandreu, David; Casademunt Viader, Jaume (American Institute of Physics (AIP), 2013-07-26)
      Article
      Accés obert
      KIF1A is a kinesin motor protein that can work processively in a monomeric (single-headed) form by using a noise-driven ratchet mechanism. Here, we show that the combination of a passive diffusive state and finite-time ...

    • Diferents estats d’oligomerització entre els receptors 5-HT1A, GALR1 I GPR39 com a noves dianes terapèutiques en depressió 

      Tena Campos, Mercè (Universitat Politècnica de Catalunya, 2015-06-16)
      Tesi

    • Emulsion copolymerization of n-Butyl acrylate with modified glucose 

      Garcia Blanch, Elisa (Universitat Politècnica de Catalunya / Univerza Ljubljani, 2013)
      Treball Final de Grau
      Accés restringit per decisió de l'autor
      Realitzat a/amb:   Univerza v Ljubljani
      In the present work an emulsion copolymerization of n-butyl acrylate monomer and secondary renewable monomer derived from glucose is presented. The latter component offers to this study a plus of sustainability, considering ...

    • Eugenol-based dual-cured materials with multiple dynamic exchangeable bonds 

      Roig Gibert, Adriá; Ramis Juan, Xavier; De la Flor López, Silvia; Serra Albet, Maria Àngels (Elsevier, 2024-02-21)
      Article
      Accés obert
      In the present work, the preparation of sustainable thermosets has been approached simultaneously from three different points of view: a) the use of bio-based monomers chemically modified through green methodologies, b) ...

    • Harnessing disulfide and transesterification bond exchange reactions for recyclable and reprocessable 3D-printed vitrimers 

      Vilanova Pérez, Anna; Moradi, Sasan; Konuray, Ali Osman; Ramis Juan, Xavier; Roig Gibert, Adriá; Fernández Francos, Xavier (2024-02-01)
      Article
      Accés obert
      Two new vitrimeric materials have been studied for potential additive manufacturing applications such as 3D- printing. A monomer containing disulfide bonds and ß-hydroxyesters was easily synthesized from two low- cost and ...
