      Urzúa Acevedo, Marcela; Sandoval, Claudia; González Nilo, Fernando; Leiva, Angel; Gargallo, Ligia; Radic, Deodato (JOHN WILEY, 2006-11-05)
      The phase behavior of blends containing N-alkylitaconamic acid-co-styrene copolymers (NAIA-co-S) with poly(N-vinyl-2-pyrrolidone) (PVY) of two different weight average molecular weights (M-w($) over bar), poly(2-vinylpyridine) ...
    • Monolayers and Thin Films of Dextran Hydrophobically Modified 
      Leiva, Angel; Muñoz, Natalia; Urzúa Acevedo, Marcela; Gargallo, Ligia; Radic, Deodato (Sociedade Brasileira de Química, 2010)
      Foram sintetizados uma série de copolímeros enxertados biodegradáveis pelo enxerto da e-captolactona sobre dextrana de diferentes pesos moleculares. Os polímeros obtidos foram caracterizados por infravermelho com transformada ...
    • New Hybrid Nanocomposites with Catalytic properties obtained by In situ preparation of gold nanoparticles ... 
      Ramírez, Oscar; Leal, Matías; Briones Olaran, Ximena Gabriela; Urzúa Acevedo, Marcela del Pilar; Bonardd, Sebastián; Saldías, César; Leiva, Angel (MDPI, 2022)
      In this work, we report the obtaining of new hybrid nanocomposites with catalytic activity formed by nanofibers of polymer blends and gold nanoparticles. The nanofibers were obtained by electrospinning blends of a poly ...
    • On the versatile role of electrospun polymer nanofibers as photocatalytic hybrid materials applied to ... 
      Córdoba, Alexander; Saldías, César; Urzúa Acevedo, Marcela del Pilar; Montalti, Marco; Guernelli, Moreno; Focarete, Maria Letizia; Leiva, Angel (MDPI, 2022)
      A wide variety of materials, strategies, and methods have been proposed to face the challenge of wastewater pollution. The most innovative and promising approaches include the hybrid materials made of polymeric nanofibers ...
    • Poly(ethylene oxide)s hydrophobically modified. Adsorption and spreading at the air-water interface 
      Leiva, Angel; Urzúa Acevedo, Marcela; Gargallo, Ligia; Radic, Deodato (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-07-01)
      A comparative study of spread and adsorbed monolayer of poly(ethylene oxide)s of different molecular weight hydrophobically modified with alkyl isocyanates of different length chain is reported. The modification of the ...
    • Thermal studies of poly(esters) containing silicon or germanium in the main chain 
      Tagle, L. H.; Terraza, C.; Valenzuela, Patricio; Leiva, Angel; Urzúa Acevedo, Marcela (ELSEVIER SCIENCE BV, 2005-06-20)
      The thermal properties of poly(esters) containing Si and/or Ge in the main chain derived from the acid dichlorides bis(4-chloroformylphenyl)-dimethyl-silane, bis(4-chloroformyl-phenyl)-dimethyl-germane, bis(4-chlorofonny ...
