Multi-Wavelength Observations and Modeling of Loop I
Galaxies, 2018 The article aims to overview the origin and current dynamical state of a giant structure on the northern galactic sky—the radio Loop I extending from ≈ − 45 ∘ to ≈ + 45 ∘ in longitudes and up to ≈ 80 ...

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.Deprotonotion of a β‐diketiminate ligand with a tethered secondary amine resulted in highly stable heteroleptic complexes, but the formation of the dianionic ligand could not be achieved. The alkaline‐earth (Ae) metal chemistry of a β‐diketiminate (BDI) ligand with a bulky Ar‐substituent and a pendant amine arm was investigated. The ligand precursor HC[

Dust formation and evolution in the ejecta of core-collapse supernovae [PDF]
, 2015 Observations of local supernovae over the past couple of decades have reported the presence of dust in the ejecta. The dust masses inferred from observations in mid-infrared and submillimeter wavelengths differ by a factor of 10^2 to 10^4 The composition

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 ...

Chemistry – A European Journal, Volume 32, Issue 25, 2 July 2026.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.

International Journal of Modern Physics A, 2005 The origin of cosmic rays (CR) is supposed to be closely connected with supernovae (SNe) which create the conditions favorable for various mechanisms of the CR acceleration to operate effectively. First, modern ideas about the physics of the SN explosion are briefly discussed: the explosive thermonuclear burning in degenerate white dwarfs resulting in

, 2019 There is a great deal of primary and specialist literature on supernovae, with a great many scientific groups around the world focusing on the phenomenon and related subdisciplines, but what is missing is a comprehensive and balanced reference work that ...

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

Type Ib and Ic supernovae: Models and spectra [PDF]
, 1996 In this paper we consider the properties of massive star models for type Ib and Ic supernovae. There are two ways that a massive star can lose its hydrogen envelope - binary mass exchange and stellar wind. These are not mutually exclusive.
