while a secondary battery cell can provide electrical energy during discharge and then be restored to its original charged condition through an electric current flowing in the opposite direction of discharge (i.e., charge) [2]. Thus, secondary batteries ...
The calibrant information for a broad standard is a slice table of mass fraction vs. molecular weight (for example Table S4), which is a property of the calibrant material, theoretically independent of the chromatographic system used. In principle therefore, the broad standard calibrant should be ...

Designing molecular materials with very large exciton diffusion lengths would remove some of the intrinsic limitations of present-day organic optoelectronic devices. Yet, the nature of excitons in these materials is still not sufficiently well understood. Here we present Frenkel exciton surface hopping, ...
