Advanced Energy Materials, EarlyView.This concept article provides a comprehensive introduction and overview of how (fully) organic batteries and the respective redox‐active organic electrode materials work. Options for cell setups are discussed, as well as the difference between half‐ and full‐cells and the relevance of the two types. At the material level, the difference between organic

Weyl geometry in late 20th century physics [PDF]
arXiv, 2011 Weyl's original scale geometry of 1918 ("purely infinitesimal geometry") was withdrawn from physical theory in the early 1920s. It had a comeback in the last third of the 20th century in different contexts: scalar tensor theories of gravity, foundations of physics (gravity, quantum mechanics), elementary particle physics, and cosmology.

Urban vegetation change after a hundred years in a tropical city (San José de Costa Rica) [PDF]
Rev. Biol. Trop. (Int. J. Trop. Biol. ISSN-0034-7744) Vol. 58 (4):
1367-1386, December 2010, 2015 Urban vegetation is of key importance because a large proportion of the human population lives in cities. Nevertheless, urban vegetation is understudied outside central Europe and particularly, little is known about the flora of tropical Asian, African and Latin American cities.

Influenza Pandemics of the 20th Century
Emerging Infectious Diseases, 2006 Three worldwide (pandemic) outbreaks of influenza occurred in the 20th century: in 1918, 1957, and 1968. The latter 2 were in the era of modern virology and most thoroughly characterized. All 3 have been informally identified by their presumed sites of origin as Spanish, Asian, and Hong Kong influenza, respectively.

Animacy in early New Zealand english [PDF]
, 2012 The literature suggests that animacy effects in present-day spoken New Zealand English (NZE) differ from animacy effects in other varieties of English. We seek to determine if such differences have a history in earlier NZE writing or not.
