Black Conservative Intellectuals in Modern America

open access: yes, 2010
In Black Conservative Intellectuals in Modern America, Michael L. Ondaatje delves deeply into the historical archive to chronicle the origins of black conservatism in the United States from the early 1980s to the present. Focusing on three significant policy issues-affirmative action, welfare, and education-Ondaatje critically engages with the ideas of

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 ...

A cidade como experimento: a arte de João Timotheo da Costa no Rio de Janeiro da Primeira República (1890-1930)

open access: yesInterseções
Interpreting the urban experience beyond the materiality of its constitution broadens the emphasis on the elements that give life to a city. Themes focused on social trajectories are analytical possibilities for understanding the ways in ...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

open access: yesAdvanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

The African Woman as a Symbol of her Continent in Wole Soyinka’s The Lion and the Jewel

open access: yesTraduction et Langues, 2020
This paper is intended to offer a feminist reading of Wole Soyinka’s play The Lion and the Jewel by showing that its main women figures are constructed as tropes of Africa rather than being depicted as full-fledged individuals. Besides being deprived of

Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature

open access: yesAdvanced Materials, EarlyView.
We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

Mechanistically Interpretable Artificial Intelligence for Designing Oxygen Electrocatalysts

open access: yesAdvanced Materials, EarlyView.
Mechanistically interpretable artificial intelligence screens nearly seven million perovskite compositions and identifies key descriptors—d‐p hybridization and densification resistance—that govern oxygen electrocatalysis. The discovered BaCo0.8Nb0.1Zr0.1O3‐δ achieves a record 2.68 W cm−2 peak power density at 600°C with over 500 h of durable operation ...
