OXIDATION‐DEFORMYLATION CASCADE CATALYZED BY A MONONUCLEAR COPPER COMPLEX
Chemistry – A European Journal, Accepted Article.In this study, two copper complexes were synthesized using N3 (arising from two pyridines and one amide group) containing ligands N‐(2‐picolyl)picolinamide (L1H) and bis(2‐pyridylcarbonyl)amine (L2H), forming [(L1)CuII(OH2)(NO3)] (1) and [(L2)CuII(OH2)2](NO3) (2).

The physics of asymmetric supernovae and supernovae remnants [PDF]
Advances in Applied Physics, 2018 We model the circumstellar medium with four density profiles: hyperbolic type, power law type, exponential type and Gaussian type. We solve analytically or numerically the four first-order differential equations which arise in the framework of the classical thin layer approximation.

Chemistry – A European Journal, Accepted Article.The direct derivatisation of heteroleptic iridium(III) complexes with sulfonate groups removes the limitations of prior strategies for the preparation of water‐soluble analogues, in which complexes were prepared from a narrow range of ligands with suitably polar or charged functional groups.

Neutrino flavor instabilities in a time-dependent supernova model
Physics Letters B, 2015 A dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction among the neutrinos.

Supernova Dust Evolution Probed by Deep-sea 60Fe Time History
The Astrophysical Journal, 2023 There is a wealth of data on live, undecayed ^60 Fe ( t _1/2 = 2.6 Myr) in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as originating from the recent explosions of at least two near-Earth supernovae.

SOUSA's Swift Supernova Siblings [PDF]
arXiv, 2015 Swift has observed over three hundred supernovae in its first ten years. Photometry from the Ultra-Violet Optical Telescope (UVOT) is being compiled in the Swift Optical/Ultraviolet Supernovae Archive (SOUSA). The diversity of supernovae leads to a wide dynamic range of intrinsic properties.

Circumstellar Nebulae in Young Supernova Remnants [PDF]
, 2000 Supernovae descendent from massive stars explode in media that have been modified by their progenitors' mass loss and UV radiation. The supernova ejecta will first interact with the circumstellar material shed by the progenitors at late evolutionary stages, and then interact with the interstellar material.

Modelling the progenitors of Core-Collapse Supernovae [PDF]
arXiv, 2004 We present details of our investigation of the progenitors to core-collapse supernovae. We discuss observations and the theory of the lowest-mass stars to explode as supernovae.
arxiv
Nuclear Physics B - Proceedings Supplements, 2001 The Sudbury Neutrino Observatory (SNO) has unique capabilities as a supernova detector. In the event of a galactic supernova there are opportunities, with the data that SNO would collect, to constrain certain intrinsic neutrino properties significantly, to test details of the various models of supernova dynamics, and to provide prompt notification to ...

Combining Low‐Valent AlI and SnII Metal Centers for Small Molecule Activation
European Journal of Inorganic Chemistry, Accepted Article.Reaction of the AlI complex (DIPPBDI‐H)AlˉK+ with the SnII complex (DIPPBDI)SnCl gave (DIPPBDI‐H)AlSn(DIPPBDI) (1); DIPPBDI = HC[C(Me)N(DIPP)]2, DIPP = 2,6‐diisopropylphenyl, DIPPBDI‐H = H2C=C(N‐DIPP)‐C(H)=C(Me)‐N‐DIPP. The crystal structure shows an asymmetric complex with a planar but strongly distorted trigonal coordination geometry at Al and ...
