Mediator-Enabled Electrocatalysis with Ligandless Copper for Anaerobic Chan-Lam Coupling Reactions.
Journal of the American Chemical Society, 2021 Simple copper salts serve as catalysts to effect C-X bond-forming reactions in some of the most utilized transformations in synthesis, including the oxidative coupling of aryl boronic acids and amines.

Autocatalytic photoredox Chan-Lam coupling of free diaryl sulfoximines with arylboronic acids
Nature Communications, 2021 N-Arylation of NH-sulfoximines represents an appealing approach to access N-aryl sulfoximines, but has not been successfully applied to NH-diaryl sulfoximines.

Memes, Radicalisation, and the Promotion of Violence on Chan Sites
International Conference on Web and Social Media, 2021 A number of violent far-right attacks in recent years have revealed an apparent connection with `chan culture', not just in the tangible examples of attackers uploading manifestos, final messages and livestreams to chan sites themselves, but in the ...

Scale-discretised ridgelet transform on the sphere [PDF]
, 2019 We revisit the spherical Radon transform, also called the Funk-Radon transform, viewing it as an axisymmetric convolution on the sphere. Viewing the spherical Radon transform in this manner leads to a straightforward derivation of its spherical harmonic ...

Mechanistic Development and Recent Applications of the Chan-Lam Amination.
Chemical Reviews, 2019 Transition metal-mediated formation of C-N bonds is an essential synthetic methodology. The discovery of the Chan-Lam amination provided a C-N bond forming process that was mild, convenient, and inexpensive, offering an alternative to complementary ...

Joseph, Jehoiachin, and Cyrus: On Book Endings, Exoduses and Exiles, and Yehudite/Judean Social Remembering [PDF]
, 2014 In a recent ZAW article, Michael Chan argues that II Reg 25,27-30 alludes to Gen 40-41, and that this allusion provides a hermeneutical key for understanding the purpose of II Reg 25,27-30 in an Enneateuchal context: it points to an imminent exodus, a ...

Mineral pigments at Huaca Tacaynamo (Chan Chan, Peru)
Bulletin de l'Institut Français d'Études Andines, 2008 X-ray diffraction analyses of five samples of pigments from a recently excavated mural at the archaeological site of Huaca Tacaynamo, a part of the Chan Chan archaeological complex, northern Peru, show that minerals related to metal occurrences known to ...

Black hole solutions in 2+1 dimensions [PDF]
, 1995 We give circularly symmetric solutions for null fluid collapse in 2+1-dimensional Einstein gravity with a cosmological constant. The fluid pressure $P$ and energy density $\rho$ are related by $P=k\rho$ $(k\le 1)$.
