A catalytic cycle for oxidation of tert-butyl methyl ether by a double C−H activation-group transfer process [PDF]

, 2008
A square-planar, iridium(I) carbene complex is shown to effect atom and group transfer from nitrous oxide and organic azides, releasing the corresponding formate or formimidate and an iridium(I)−dinitrogen adduct.

Till death (or an intruder) do us part: intrasexual-competition in a monogamous Primate [PDF]

, 2012
Polygynous animals are often highly dimorphic, and show large sex-differences in the degree of intra-sexual competition and aggression, which is associated with biased operational sex ratios (OSR).

The Degradation of Daguerreotypes and the Relationship with Their Multi-Material Structure: A Multimodal Investigation

Sensors, 2023
Preserving and analytically examining daguerreotypes is particularly challenging because of their multi-material and multi-component structure. Various sensors have been exploited to examine mainly the image plates of the daguerreotypes even though the ...
