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

open access: yesAdvanced 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 ...

On Nominatives Joining or ‘Replacing’ Vocatives [PDF]

open access: yesLingua, 1956
Abstract The construction Zeṽ πα'τeϱ ... 'He'λιoζ τe may probably be explained by the tendency to avoid ‘Ubercharakterisierung’, the nominative often replacing other forms of a noun. With regard to the grammatical form of an attribute of a vocative there does not seem to have been a generally accepted idiom in prehistoric times.

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

open access: yesAdvanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

The syntax of Arabic vocatives

open access: yesBrill’s Journal of Afroasiatic Languages and Linguistics, 2019
Abstract This paper examines the syntactic structure of Arabic vocatives, focusing on case-marking of vocatives. The assignment of accusative and nominative-like case can be accounted for in the light of Hill (2017)’s proposal which provides the basic structure of the vocative phrase.
