Blendas biodegradáveis de poli(3-hidroxibutirato)/poli(e-caprolactona): obtenção e estudo da miscibilidade

Materials Research, 2003
Due to its biodegradability, poly(3-hydroxybutyrate) P(3-HB) has attracted much attention in the environmental sector. However, some characteristics of this polymer, such as high crystallinity, poor processability and high brittleness, have lead several ...

Solubility improvement of progesterone from solid dispersions prepared by solvent evaporation and co-milling [PDF]

, 2020
The aim of this contribution was to evaluate the impact of processing methods and polymeric carriers on the physicochemical properties of solid dispersions of the poorly soluble drug progesterone (PG). Five polymers: hydroxypropyl methylcellulose (HPMC),

Metastable liquid-liquid and solid-liquid phase boundaries in polymer-solvent-nonsolvent systems [PDF]

, 1997
In general liquid-liquid demixing processes are responsible for the porous morphology of membranes obtained by immersion precipitation. For rapidly crystallizing polymers, solid-liquid demixing processes also generate porous morphologies.

A scalable parallel Monte Carlo algorithm for atomistic simulations of precipitation in alloys [PDF]

, 2012
We present an extension of the semi-grandcanonical (SGC) ensemble that we refer to as the variance-constrained semi-grandcanonical (VC-SGC) ensemble. It allows for transmutation Monte Carlo simulations of multicomponent systems in multiphase regions of ...

Considerations on the Kinetic Processes in the Preparation of Ternary Co-Amorphous Systems by Milling

Pharmaceutics, 2023
In non-strongly interacting co-amorphous systems, addition of a polymer, to further stabilize the co-amorphous systems, may influence the phase behavior between the components. In this study, the evolution of the composition of the amorphous phase in the
