Type II supernovae at high redshifts [PDF]

, 2000
A hydro code coupled with radiation transfer was applied to produce monochromatic light curves of two models of type II supernovae (SN II) simulating SN II-P and SN IIb (SN 1993J-like).

From Phosphinimines to Four‐Membered SiCPN Cations: Insights Into N–Si Bonding and Ring Strain

European Journal of Inorganic Chemistry, Volume 29, Issue 18, 22 June 2026.
Sterically tuned N‐silyl phosphinimines enable four‐membered SiCPN cations. Hydride abstraction yields cyclic cations for Me and iPr substituents at silicon, while tBu gives a protonated intermediate. Multinuclear NMR spectroscopy, X‐ray crystallography, thermochemical density functional theory investigations, and natural bond orbital analyses reveal ...

Synthesis, Characterization, and Anti‐Plasmodium falciparum Activity of a New Copper(II) Complex Containing 2‐(Tert‐Butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine

ChemMedChem, Volume 21, Issue 11, 15 June 2026.
The graphical abstract illustrates the formation of a Cu(II) complex from azole‐based ligand, highlighting metal–ligand synergy. The resulting coordination compound acts as a bioactive entity against Plasmodium, where metal coordination enhances antiparasitic activity, outperforming the free ligand and demonstrating its potential as an antimalarial ...

Type II-P supernovae as standardized candles: improvements using near-infrared data [PDF]

, 2010
We present the first near-infrared Hubble diagram for Type II-P supernovae (SNe), to further explore their value as distance indicators. We use a modified version of the standardized candle method, which relies on the tight correlation between the ...

Synthesis, Biological Evaluation, and Molecular Docking Studies of 2r,3t,4c‐Configured C‐Furanosidic LpxC Inhibitors

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
To provide a full picture of the effects of stereochemistry on the biological activity of C‐furanosidic LpxC inhibitors, in chiral pool syntheses starting from d‐mannitol and d‐galactose, a series of four 2r,3t,4c‐configured C‐furanosides was synthesized and tested for LpxC inhibitory and antibacterial activity as well as in vitro ADMET properties ...

Magnetorotational Mechanism of Supernova Type II Explosion

International Astronomical Union Colloquium, 2005
SummaryResults of 2D simulations of the magnetorotational mechanism of supernova type II are presented. Amplification of toroidal magnetic field of the star due to differential rotation of the star leads to the transformation of the rotational (gravitational) energy to the energy of the supernova explosion. In our simulation the energy of the explosion

Type II supernovae as distance indicators at near-IR wavelengths [PDF]

, 2018
Motivated by the advantages of observing at near-IR wavelengths, we investigate Type II supernovae (SNe II) as distance indicators at those wavelengths through the Photospheric Magnitude Method (PMM). For the analysis, we use BVIJH photometry and optical
