Synthesis and Characterization of [MF5(terpy)]+ (M = Mo, W) Salts: Autoionization of MF6 Induced by a Tridentate Ligand

Chemistry – A European Journal, EarlyView.
The hexafluorides MoF6 and WF6 autoionize in the presence of the tridentate terpyridine ligand, yielding [MF5(terpy)]+[MF7]– (M = Mo, W). The octacoordinated [MF5(terpy)]+ cations adopt bicapped trigonal prismatic geometries. The [WF7]– can be substituted for [SbF6]– using SbF5SO2, whereas the reaction was unsuccessful for displacing the [MoF7]– anion.

The Carnegie Supernova Project: First Photometry Data Release of Low-Redshift Type Ia Supernovae [PDF]

, 2009
The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ~100 low-redshift Type Ia supernovae in a well-defined photometric system.

Exploring the Radiation Damage of Vacancy‐Ordered Double Perovskites, ((NH4)(1−x)FAx)2SnBr6

ChemPhysChem, EarlyView.
Incident X‐ray photons hν on a newly reported vacancy‐ordered double perovskite FA2SnBr6 results in damage of the compound. This is seen over increasing X‐ray dose using X‐ray photoelectron spectroscopy. Degradation studies of the ASnX3 perovskites to the A2SnX6 vacancy‐ordered double perovskite form have been well researched, but little is known about

Recent Type II Radio Supernovae

, 2007
We present the results of radio observations, taken primarily with the Very Large Array, of Supernovae 1993J, 2001gd, 2001em, 2002hh, 2004dj, and 2004et. We have fit a parameterized model to the multi-frequency observations of each supernova.

Absolute Magnitude Distribution And Light Curves Of Gamma-Ray Burst Supernovae [PDF]

, 2008
Photometry data were collected from the literature and analyzed for supernovae that are thought to have a gamma-ray burst association. There are several gamma-ray burst afterglow light curves that appear to have a supernova component.

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...

Measuring the Upper End of the Initial Mass Function with Supernovae [PDF]

, 2010
Supernovae arise from progenitor stars occupying the upper end of the initial mass function. Their extreme brightness allows individual massive stars to be detected at cosmic distances, lending supernovae great potential as tracers of the upper end of ...

Gold(I) Phosphine/Phosphido‐Borohydride Complexes

European Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

EXPLOSIVE NUCLEOSYNTHESIS AT STRONG STELLAR MAGNETIZATION

Odessa Astronomical Publications, 2014
Synthesis of iron group nuclides is considered for the ultra-magnetized astrophysical plasma in supernovae. Magnetic modification of nuclear structure is shown to shift maximum of nucleosynthesis products towards smaller mass numbers enhancing titanium ...
