When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Use of Electrical Impedance Spectroscopy (EIS) to monitor cryoprotectant concentration in cellular and tissue cryopreservation protocols

, 2010
In this paper we theoretically analyse the use of Electrical Impedance Spectroscopy (EIS) to efficiently monitor cryoprotectant concentration in cryopreservation protocols. In order to correctly determine the perfusion of cryoprotectant inside tissues and organs, with its spatial distribution, it is necessary to previously study the influence that the ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of
