Chlorido(4-methylpyridin-2-amine-κN1)(2-{[(4-methylpyridin-2-yl)imino-κN]methyl}phenolato-κO)copper(II)

Acta Crystallographica Section E, 2012
In the title complex, [Cu(C13H11N2O)Cl(C6H8N2)], the CuII atom adopts a distorted tetrahedral geometry being coordinated by the phenolic O atom and the azomethine N atom of the Schiff base ligand N-salicylidene 2-aminopyridine, and by the 2-aminopyridine

Atomic White-Out: Enabling Atomic Circuitry Through Mechanically Induced Bonding of Single Hydrogen Atoms to a Silicon Surface

, 2017
We report the mechanically induced formation of a silicon-hydrogen covalent bond and its application in engineering nanoelectronic devices. We show that using the tip of a non-contact atomic force microscope (NC-AFM), a single hydrogen atom could be ...

Shielding resources for four common radiopharmaceuticals utilized for imaging and therapy: Tc‐99m, F‐18, I‐131, and Lu‐177

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction The use of radioactive materials in the United States has been tightly regulated by the Nuclear Regulatory Commission and other entities for many decades. In 2015, however, the Joint Commission began to require hospital‐based nuclear medicine departments to conduct shielding designs and evaluations for radioactive material areas ...

On the energy of electric field in hydrogen atom [PDF]

arXiv, 2009
It is shown that hydrogen atom is a unique object in physics having negative energy of electric field, which is present in the atom. This refers also to some hydrogen-type atoms: hydrogen anti-atom, atom composed of proton and antiproton, and positronium.

Study on synergistic effects of H and He in α-Fe

Nuclear Materials and Energy, 2018
The synergistic effect of hydrogen and helium in α-Fe has been investigated using density functional theory calculation method. In perfect crystal of Fe, the presence of helium atom would decrease the dissolution energy of hydrogen atom near helium atom.

Hydrogen bond interactions of coumarin-153 in molecular solvents: molecular dynamics and principal component analysis

Comptes Rendus. Chimie
Hydrogen bond interactions significantly affect the coumarin-153’s (C153) photophysics, including its ability to act as a donor of weak hydrogen bonds via its 14 C–H bonds and as an acceptor via its O atoms in the ester and the carbonyl groups, as well ...

Semi-classical analysis of real atomic spectra beyond Gutzwiller's approximation

, 2005
Real atomic systems, like the hydrogen atom in a magnetic field or the helium atom, whose classical dynamics are chaotic, generally present both discrete and continuous symmetries.

Characterization and Optimization of Vesicle Properties in bioPISA: from Size Distribution to Post‐Assembly Loading

Advanced Biology, EarlyView.
The paper explores the creation and characterization of vesicles through biocatalytic Polymerization‐Induced Self‐Assembly (bioPISA), focusing on achieving size uniformity using centrifugation techniques. It examines the effects of stirring speed on vesicle morphology and analyses the internal polymer‐rich structure using fluorescence correlation ...
