Chemistry – A European Journal, EarlyView.Open halogen‐bonded networks have been prepared from building blocks that incorporate both iodoalkyne halogen bond donors and a pyridine‐N‐oxide halogen bond acceptor. An initially‐formed 3D network containing dioxane in its channels undergoes an unprecedented transition to a 2D material when crystals are exposed to diethyl ether.

Bolometric Luminosities of Peculiar Type II-P Supernovae [PDF]
, 2018 In this work, I analyze the bolometric luminosities of several peculiar Type II-P supernovae which are thought to originate from the same class of blue supergiant progenitor stars as the famous SN 1987A.

, 2007 All core collapse supernovae are strongly aspherical. The >Bochum event> with velocity components displaced symmetrically about the principal H alpha line, strongly suggests that SN 1987A was a bi-polar rather than a uni-polar explosion.

General constraints on Tsallis holographic dark energy from observational data [PDF]
Physics of the Dark UniverseWe investigated Tsallis holographic dark energy (THDE) model in light of modern observations of supernovae, Hubble parameter measurements, data for baryon acoustic oscillations and fluctuations of matter density. The dark energy density for THDE model is

Feedback from the First Supernovae in Protogalaxies: The Fate of the Generated Metals
The Astrophysical Journal, 2003 We investigate the chemo-dynamical effects of multiple supernova explosions in the central region of primordial galaxies using three-dimensional hydrodynamical simulations of the inhomogenous interstellar medium down to parsec-scales. We find that the final protogalactic structure and metal distribution depend strongly on the number of SNe ...

Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism
Chemistry – A European Journal, EarlyView.A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]

General Relativistic Explosion Models of Core-Collapse Supernovae
, 2011 We present results from the first generation of multi-dimensional general relativistic neutrino hydrodynamics simulations of core-collapse supernovae. A comparison with models computed using either the purely Newtonian approximation or the "effective gravitational potential" approach reveals appreciable quantitative differences in the heating ...

Generalized Chaplygin Gas Models Tested with Type Ia Supernovae
The Astrophysical Journal, 2005 The generalized Chaplygin gas (GCG), with the equation of state p = -A/ρα, was recently proposed as a candidate for dark energy in the universe. In this paper we confront the GCG with Type Ia supernova (SN Ia) data using available samples. Specifically, we have tested the GCG cosmology in three different classes of models with (1) Ωm = 0.3 and ΩCh = 0 ...

EcoEnergy, EarlyView.We develop a highly cost‐effective heterogeneous catalyst for efficient CO2 conversion to propiolic acid under mild conditions via a nano‐confined approach with porous MIL support. ABSTRACT Efficient conversion of carbon dioxide to organics has been a promising outlet for value‐added carbon dioxide consumption.
