Coating typologies and constrained swelling of hyaluronic acid gels within scaffold pores

Arnal Pastor, María Pilar; Vallés Lluch, Ana; Keicher, Matthias; Monleón Pradas, Manuel (Elsevier, 2011)

[EN] A set of elastomeric scaffolds with a well defined porous structure was prepared with a template leaching procedure and coated with hyaluronic acid solutions. Depending on the coating process parameters the hyaluronic ...
Finely tuned temperature-controlled cargo release using paraffin-capped mesoporous silica nanoparticles

Aznar Gimeno, Elena; Mondragón Martínez, Laura; Ros-Lis, José Vicente; Sancenón Galarza, Félix; Marcos Martínez, María Dolores; Martínez Mañez, Ramón; Soto Camino, Juan; Pérez Payá, Enrique; AMOROS DEL TORO, PEDRO (Wiley-VCH Verlag, 2011-09-27)

Trapped: Mesoporous silica nanoparticles were loaded with a fluorescent guest and functionalized with octadecyltrimethoxysilane. The alkyl chains interact with paraffins, which build a hydrophobic layer around the particle ...
Highly effective activation of aryl chlorides for Suzuki coupling in aqueous media using a ferrocene-based Pd(II) diimine catalyst

Hanhan, Emre Murat; Martínez Mañez, Ramón; Ros-Lis, José Vicente (Elsevier, 2012-05-09)

The Suzuki coupling of aryl chlorides with boronic acids using a ferrocene-containing Pd(II)-diimine complex as catalyst, in aqueous media, under microwave heating is reported. A small amount of the catalyst (0.1%) was ...
