Recent progress of all-polymer solar cells – From chemical structure and device physics to photovoltaic performance
Publication date: April 2020Source: Materials Science and Engineering: R: Reports, Volume 140Author(s): Hang Yin, Cenqi Yan, Hanlin Hu, Johnny Ka Wai Ho, Xiaowei Zhan, Gang Li, Shu Kong SoAbstractSingle junction organic solar cells (OSCs) have now achieved power conversion efficiencies (PCEs) exceeding 17 %. Most of these high performance OSCs contain fullerene acceptors (FAs) and non-fullerene small-molecule acceptors (NFSMAs). In contrast, there are very limited usages of polymer acceptors. Recently, there are escalating recognition among perylene-diimide/naphthalene-diimide (PDI/NDI) and B⟵N-unit n-type polymers as el...

Materials for blood brain barrier modeling in vitro
Publication date: April 2020Source: Materials Science and Engineering: R: Reports, Volume 140Author(s): Magali P. Ferro, Sarah C. Heilshorn, Roisin M. OwensAbstractBrain homeostasis relies on the selective permeability property of the blood brain barrier (BBB). The BBB is formed by a continuous endothelium that regulates exchange between the blood stream and the brain. This physiological barrier also creates a challenge for the treatment of neurological diseases as it prevents most blood circulating drugs from entering into the brain. In vitro cell models aim to reproduce BBB functionality and predict the passage of active...
