A Three‐Dimensional Structural Model for Predicting Magnetic Exchange and Hydrogen Positions in Bis‐μ‐Hydroxido Cu(II) Dimers

European Journal of Inorganic Chemistry, EarlyView.
Magneto‐structural correlation in bis‐μ‐hydroxido Cu(II) dimers: The out‐of‐plane angle (α) of bridging hydroxido groups critically influences the exchange coupling constant (J). A three‐dimensional correlation combining α and the Cu‐OH‐Cu angle (θ) enables computationally accurate J prediction.

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

European Journal of Inorganic Chemistry, EarlyView.
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 ...

Supernova 1604, Kepler’s Supernova, and Its Remnant [PDF]

, 2016
Supernova 1604 is the last Galactic supernova for which historical records exist. Johannes Kepler's name is attached to it, as he published a detailed account of the observations made by himself and European colleagues. Supernova 1604 was very likely a Type Ia supernova, which exploded 350 pc to 750 pc above the Galactic plane.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

SNO and supernovae [PDF]

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 ...

Easily Accessible and Up‐Scalable Aliphatic Bis‐Formamides with Afterglow Luminescence: Photoluminescence Properties and Applications

Small, EarlyView.
A bis formamide molecule was found to feature afterglow properties, in both crystalline powder state and in polyvinyl alcohol films. This was attributed to the intermolecular packing that allows H‐trapped emitting state and/or clustering‐triggered emission, which was intensified upon insertion of tetramethylbenzidine as a doping agent.

Alkaline‐Earth Metal Complexes Based on Tridentate β‐Diketiminate Ligands Bearing a Tethered Secondary Amine: Synthesis and Characterization

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
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[

Whole Genome Assembly and Annotation of Two Invasive Sitona Species

Journal of Applied Entomology, EarlyView.
ABSTRACT Weevils are a highly diversified taxon, comprising about 70,000 described species, including many of high economic importance. Here, we present whole genome assemblies and annotations of two Sitona species (Coleoptera: Curculionidae: Entiminae).

INTERACTING SUPERNOVAE AND SUPERNOVA IMPOSTORS: SN 2009ip, IS THIS THE END? [PDF]

The Astrophysical Journal, 2013
We report the results of a 3 year-long dedicated monitoring campaign of a restless Luminous Blue Variable (LBV) in NGC 7259. The object, named SN 2009ip, was observed photometrically and spectroscopically in the optical and near-infrared domains.
