A molecular photosensitizer achieves a Voc of 1.24 V enabling highly efficient and stable dye-sensitized solar cells with copper(II/I)-based electrolyte

open access: yesNature Communications, 2021
To develop photosensitizers with high open-circuit photovoltage (Voc) is a crucial strategy to enhance the power conversion efficiency (PCE) of co-sensitized solar cells.

SARS-CoV-2 Omicron VOC Transmission in Danish Households

open access: yesmedRxiv, 2021
The Omicron variant of concern (VOC) is a rapidly spreading variant of SARS-CoV-2 that is likely to overtake the previously dominant Delta VOC in many countries by the end of 2021.

Oxygenated volatile organic compounds (VOCs) as significant but varied contributors to VOC emissions from vehicles

open access: yesAtmospheric Chemistry and Physics, 2022
. Vehicular emissions are an important source for volatile organic compounds (VOCs) in urban and downwind regions. In this study, we conducted a chassis dynamometer study to investigate VOC emissions from vehicles using gasoline, diesel, and liquefied ...

Vocatives with determiners: the case of vocatives preceded by possessives

open access: yesIsogloss. Open Journal of Romance Linguistics, 2020
In some varieties of Spanish (American, above all), possessives can appear in vocative constructions such as Mi niña, ¿qué haces? (lit. ‘My girl, what are you doing?’) in contrast to the generalization that vocatives refuse definite articles (Bosque 1996, Leonetti 1999, 2016). The aim of this investigation is to explain why this happen and to propose a

Vocatives

open access: yesPragmatics. Quarterly Publication of the International Pragmatics Association (IPrA), 2022
This paper takes a critical interactional sociolinguistic approach to examine the construction ofinterculturality(e.g., Nishizaka 1995; Mori 2003) through the use of vocatives in the discourse of a multi-cultural graduate student project group at a large American university.
