Flexoelectric Elastomer Enabled by Miscibility‐Driven Succinonitrile Molecular Rotation [PDF]

Advanced Science
Plastic crystals exhibit long‐range positional order alongside orientational disorder, positioning them between crystalline solids and liquids. Although their centrosymmetric structure suppresses intrinsic piezoelectric and ferroelectric effects, they ...

Application of Theoretical Solubility Calculations and Thermal and Spectroscopic Measurements to Guide the Processing of Triamcinolone Acetonide by Hot-Melt Extrusion [PDF]

Pharmaceutics
Background/Objectives: Triamcinolone acetonide (TA), a poorly water-soluble corticosteroid, presents formulation challenges due to limited membrane permeability. This study aimed to identify suitable drug–polymer–plasticizer systems for TA using combined

Unravelling the Miscibility of Poly(2-oxazoline)s: A Novel Polymer Class for the Formulation of Amorphous Solid Dispersions

Molecules, 2020
Water-soluble polymers are still the most popular carrier for the preparation of amorphous solid dispersions (ASDs). The advantage of this type of carrier is the fast drug release upon dissolution of the water-soluble polymer and thus the initial high ...
