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 ...

Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

open access: yesAdvanced Materials, EarlyView.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Modernism/Modernisms. The Two Souls of Modernity Before Modernity

2021
The architectural and cultural heritage built in the early decades of the twentieth century is often a critical and controversial topic. “History is always written by winners”, and in the case of cultural conflicts, the narratives of the events support the prevalence of a thesis on the others that was overshadowed, denied and then forgotten.

Modern money [PDF]

open access: possibleSSRN Electronic Journal, 1998
All modern economies have a "chartalist" or "state" money, as acknowledged by Friedrich Knapp and J. M. Keynes. In this paper, I examine the "history" of money to shed light on its origins. I also examine in detail the views of those who accepted the chartalist, or state, approach to money, from Adam Smith to Knapp and Keynes, with some discussion of ...

Modernity, modernities and modernization: Tradition reappraised

Social Science Information, 2013
The current discourse of modernity has produced many new terms to reflect the multiple conditions of social change. However, they do not automatically suggest a direct transition from the traditional but rather support a recursive modality in which present changes are not construed as fully independent of reclaimed past beliefs and actions.
