Amphiphilic COSAN and I2-COSAN crossing synthetic lipid membranes: planar bilayers and liposomes
Verdiá Báguena, Carmen; Alcaraz, Antonio; Aguilella, Vicente; Cioran, Ana M.; Tachikawa, Shoji; Nakamura, Hiroyuki; Teixidor, Francesc; Viñas, Clara Royal Society of Chemistry (2014-03)The boron-rich cobaltabisdicarbollide (COSAN) and its 8,80-I2 derivative (I2-COSAN), both of purely inorganic nature, are shown to cross through synthetic lipid membranes. These results reveal unexpected properties at the ... -
Are the Accompanying Cations of Doping Anions Influential in Conducting Organic Polymers? The Case of the Popular PEDOT
Fuentes, Isabel; Mostazo-López, María José; Kelemen, Dr. Zsolt; Compañ, Vicente; Andrio, Andreu; Morallón, Emilia; Cazorla-Amoros, Diego; Viñas, Clara; Teixidor, Francesc Wiley (2019-11-13)Conducting organic polymers (COPs) are made of a conjugated polymer backbone supporting a certain degree of oxidation. These positive charges are compensated by the doping anions that are introduced into the polymer synthesis ... -
Enhanced conductivity of sodium versus lithium salts measured by impedance spectroscopy. Sodium cobaltacarboranes as electrolytes of choice
Fuentes, Isabel; Andrio, Andreu; Teixidor, Francesc; Viñas, Clara; Compañ, Vicente Royal Society of Chemistry (2017)The development of new types of ion conducting materials is one of the most important challenges in the field of energy. Lithium salt polymer electrolytes have been the most convenient, and thus the most widely used in ... -
Probing electrophysiological activity of amphiphilic Dynorphin A in planar neutral membranes reveals both ion channel-like activity and neuropeptide translocation
Alvero González, Laidy Maidel; Perini, Deborah Aurora; Queralt-Martín, María; Peralvarez-Marin, Alex; Viñas, Clara; Alcaraz, Antonio Elsevier (2023-12)Dynorphin A (DynA) is an endogenous neuropeptide that besides acting as a ligand of the κ-opioid receptor, presents some non-opioid pathophysiological properties associated to its ability to induce cell permeability similarly ... -
Structural and dielectric properties of cobaltacarborane composite polybenzimidazole membranes as solid polymer electrolytes at high temperature
Fuentes, Isabel; Andrio, Andreu; García Bernabé, Abel; Escorihuela, Jorge; Viñas, Clara; Teixidor, Francesc; Compañ, Vicente Royal Society of Chemistry (2018)The conductivity of a series of composite membranes, based on polybenzimidazole (PBI) containing the metallacarborane salt M[Co(C2B9H11)2], M[COSANE] and tetraphenylborate, M[B(C6H5)4], M[TPB] both anions having the same ...
