Thermodynamic and Spectroscopic Studies of the Complexes Formed in Tartaric Acid and Lanthanide(III) Ions Binary Systems

Molecules, 2020
Binary complexes of tartaric acid with lanthanide(III) ions were investigated. The studies have been performed in aqueous solution using the potentiometric method with computer analysis of the data for detection of the complexes set, determination of the

Interaction of sulforaphane with DNA and RNA. [PDF]

PLoS ONE, 2015
Sulforaphane (SFN) is an isothiocyanate found in cruciferous vegetables with anti-inflammatory, anti-oxidant and anti-cancer activities. However, the antioxidant and anticancer mechanism of sulforaphane is not well understood. In the present research, we

Spectroscopic determination of acid dissociation constants of some imidazole derivatives

, 2001
WOS: 000172243900038The acid dissociation constants, pK(a), of eight biologically active imidazole derivatives were determined using a spectroscopic technique. Using the obtained acid dissociation constants, attempts were made to elucidate the structures

Characterization of amorphous carbon films from 5 nm to 200 nm on single-side polished a-plane sapphire substrates by spectroscopic ellipsometry

Frontiers in Physics, 2022
In this work, a series of amorphous carbon films were deposited on a-plane sapphire substrates by magnetron sputtering with deposition time from 15 min to 8 h, in order to investigate the thickness and optical properties in the process of growth in a non-

Determination of spectroscopic constants from rovibrational configuration interaction calculations

, 2022
Rotational constants and centrifugal distortion constants of a molecule are the essence of its rotational or rovibrational spectrum (e.g., from microwave, millimeter wave, and infrared experiments).

Optical constants of graphene measured by spectroscopic ellipsometry [PDF]

, 2010
A mechanically exfoliated graphene flake ( ? 150×380??m2) on a silicon wafer with 98 nm silicon dioxide on top was scanned with a spectroscopic ellipsometer with a focused spot ( ? 100×55??m2) at an angle of 55°. The spectroscopic ellipsometric data were

Comparative Extraction of Aluminum Group Metals Using Acetic Acid Derivatives with Three Different-Sized Frameworks for Coordination

Separations, 2021
We prepared acetic acid derivatives using three different frameworks, calix[4]arene, alkenyltrimethylol, and trihydroxytriphenylmethane, which differ in the number and size of their coordination sites.

On the electron affinity of SiN and spectroscopic constants of SiN−

The Journal of Chemical Physics, 2005
Accurate spectroscopic constants and energetics were calculated for the two lowest-lying states of SiN and SiN− employing the coupled cluster methodology and very large basis sets (up to doubly augmented sextuple-ζ quality) accounting also for core∕valence correlation, one-electron Douglas-Kroll-Hess relativistic effects, and atomic spin-orbit ...
