Evaluation of Water Activity in H2O-PEG400-PEG6000 Solutions between 318.15 and 348.15 K

Paulazzo, Micaela G.; Passamonti, Francisco Javier (American Chemical Society, 2018-05)

The vapor pressure of H2O(1)-polyethylene glycol 400(2)-polyethylene glycol 6000(3) solutions was evaluated experimentally in a temperature range between 318.15 and 348.15 K and in a broad range of concentrations. The ...

1H and 2H NMR spin–lattice relaxation probing water: PEG molecular dynamics in solution

Clop, Eduardo Matias; Perillo, Maria Angelica; Chattah, Ana Karina (American Chemical Society, 2012-09-07)

Nuclear magnetic resonance spin–lattice relaxation times (T1) measurements were performed in aqueous solutions of poly(ethylene glycol) (PEG) of 6000 Da molecular mass to study the dynamical relation between PEG and water ...

Preparation of acetates catalyzed by boric acid and/or tungstophosphoric acid-modified zirconia obtained employing polyethylene glycols as pore-forming agents

Osiglio, Lilian; Sathicq, Angel Gabriel; Pizzio, Luis Rene; Romanelli, Gustavo Pablo; Blanco, Mirta Noemi (Elsevier Science, 2017-01)

Zirconia modified with boric acid and/or tungstophosphoric acid calcined at 320 °C were prepared, characterized and used as catalysts in the production of acetates from diverse alcohols and phenols. Polyethylene glycol ...

Efecto de las propiedades estructurales de la partícula sobre la liberación de moléculas encapsuladas en sistemas lipídicos coloidales

Gordillo Galeano, Aldemar (Bogotá - Ciencias - Doctorado en Ciencias FarmacéuticasDepartamento de FarmaciaUniversidad Nacional de Colombia - Sede Bogotá, 2020-01-16)

Las nanopartículas sólidas lipídicas (SLN) y los transportadores lipídicos nanoestructurados (NLC) han atraído la atención durante más de dos décadas como una alternativa para la entrega de fármacos poco solubles en agua. ...
