Design and Investigation of Superatoms for Redox Applications: First-Principles Studies
A superatom is a cluster of atoms that acts like a single atom. Two main groups of superatoms are superalkalis and superhalogens, which mimic the chemistry of alkali and halogen atoms, respectively.

To be detectable in space via radio astronomy, molecules should have a permanent dipole moment. This is the plausible reason why HCnH chains are underproportionally represented in the interstellar medium in comparison with the isoelectronically ...

Dynamics of the Chemical Composition of Precipitation and Input of Elements in an Agricultural Area in Southern Bulgaria [PDF]
The study of the chemical composition of precipitation is an important factor in determining the input of elements and the total anthropogenic load in agroecosystems.

Anion Colorimetric Chemosensor Based on a Benzimidazole-Functionalized BODIPY Derivative
A BODIPY derivative bearing a benzimidazole unit at position 2 and an electron donor group (anthracene) at the meso position was synthetized and characterized by the usual spectroscopic techniques.

Using DFT/(B3LYP/wB97XD/B2PLYPD) and OVGF electronic structure methods with flexible atomic orbital basis sets, we examined the series of polynuclear superhalogen anions matching the (BF3(BN)nF4n+1)– formula (for n = 1-10,13,18-20) containing alternately

Development of ion chromatography methods for the determination of trace anions in ultra pure water from power plants [PDF]
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra pure water and condensed steam

A Thiophene-Based Dicyanovinyl as an Anion Chemosensor
In recent years, push–pull dicyanovinyl derivatives have been reported for several optical applications, including as fluorescent probes for cyanide ion detection.

Maximum Ionization in Restricted and Unrestricted Hartree-Fock Theory
In this paper, we investigate the maximum number of electrons that can be bound to a system of nuclei modelled by Hartree-Fock theory. We consider both the Restricted and Unrestricted Hartree-Fock models. We are taking a non-existence approach (necessary

HYDROPERICARDIUM IN BROILER CHICKENS IN IRAQ: ISOLATION AND IDENTIFICATION OF THE CAUSATIVE VIRUS
An adenovirus was successfully isolated from infected liver, spleen and pericardial fluid from infected broiler chicks in primary cell cultures prepared from chicken embryo liver and kidneys.
