This research aims to study jet downstream scour model under the influence of changes of water level. It also studies and analyzes different parameters and components of diffusion of submerged jet flow in an acceptor fluid and scour hole dimensions. To achieve the objectives, a physical model was made in proportion to the research title. With the Froude number increasing in a nozzle discharge, ...
The interaction of the perimidone drug in solution state with the σ-acceptor iodine, the aliphatic π-acceptor tetracyanoethylene (TCNE) and the aromatic π-acceptor 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) have been studied through the initial formation of ionic intermediate to charge transfer (CT) complex in methanol at room temperature. The spectral studies of the complexes were determi...
The solvatochromism of fluoresceine and its derivatives was studied in solvents of different Hydrogen Bond Donor (HBD), Hydrogen Bond Acceptor (HBA), Donor Number (DN) and Acceptor Number (AN) by their UV-Vis spectra. Results showed that position, intensity and shape of absorption bands change with type of solvent. These changes can be rationalized by solvatochromic parameters such as ...
Donor–donor?–acceptor molecules where the donor? bridges donor and acceptor have different possible interaction pathways for charge transfer.
A novel acceptor (A)–donor (D)–acceptor (A) molecular architecture for pseudocapacitor applications with imrpoved electrochemical performance is demonstrated.
We present an experimental and theoretical investigation of the linear and nonlinear optical properties of a series of acceptor-pi-acceptor symmetrical anionic polymethine dyes with diethylamino-coumarin-dioxaborine terminal groups and different conjugation lengths. Two-photon absorption (2PA) cross sections (delta(2PA)) are enhanced with an increase of pi-conjugation length in the investigated...
