Exploring the Impact of 1,8-Diioodoctane on the Photostability of Organic Photovoltaics.

Improving the photostability of the light-harvesting blend film in organic photovoltaics is crucial to achieving long-term operational lifetimes that are required for commercialization. However, understanding the degradation factors which drive instabilities is complex, with many variables such as film morphology, residual solvents, and acceptor or donor design all influencing how light and oxygen interact with the blend film. In this work, we show how blend films comprising a donor polymer (PBDB-T) and small molecule acceptor (PCBM or ITIC) processed with solvent additive (DIO) yield very different film morphologies, device performance, and photostability.

Chlorhexidine Mucoadhesive Buccal Tablets: The Impact of Formulation Design on Drug Delivery and Release Kinetics Using Conventional and Novel Dissolution Methods.

Oropharyngeal candidiasis (OPC) is a mucosal infection caused by spp., and it is common among the immunocompromised. This condition is mainly treated using oral antifungals.

The effect of the source and the concentration of polymers on the release of chlorhexidine from mucoadhesive buccal tablets.

In the current work, two groups of chlorhexidine mucoadhesive buccal tablets were prepared, using either rod or irregularly-shaped spherical particles of hydroxypropyl methylcellulose and different ratios of poloxamer 407 (P407). The tablets were designed to release the drug over two hours. Their physicochemical properties and drug release profiles were investigated.
