Density functional efficiency in the calculations of vibrational frequencies and molecular structure of β- diketones
Density functional theory (DFT) levels are employed to calculate the vibrational frequencies and
geometrical data of β-diketones. We evaluate the relative performance of the different levels by comparing
theoretical ...
Sonochemical synthesis of Zinc sulfide quantum dots and their photocatalytic activityfor dye removal
One of the most important applications of semiconductor nanoparticles (NPs) is their
photocatalytic activity degradation of toxic chemicals. It arises from their quantum-size
effects. Among semiconductor NPs, ...
Structural Properties of Silver\\\\Palladium Bimetallic Nanoparticles Fabricated by Ultrasound Method
In the present work,
the simultaneous reduction method was used to synthesis the Pd/Ag bimetallic NPs from
aqueous solutions of silver and palladium nitrate in the presence ultrasound (US) waves. The
sodium ...
Validity of some regularities of dense fluids for ionic liquids
Five of the best known regularities have been investigated for different classes of ionic liquids. The
regularities are near linearity of the isothermal bulk modulus as function of pressure, common intersection
point ...
Validity of some regularities of dense fluids for ionic liquids
Five of the best known regularities have been investigated experimentally and theoretically for different classes of ILs to develop solution theories for ionic liquids. All of this work points to the need for more experimental ...
Silver colloid nanoparticles: Ultrasound-assisted synthesis, electrical and rheological properties
We report the synthesis of silver nanoparticles using both conventional and ultrasound assisted reduction
method. The subsequent studies on the electrical conductivity and rheological properties of nanofluids ...
Voltammetric determination of 4-nitrophenol using a modified carbon paste electrode based on a new synthetic crown ether/silver nanoparticles
a novel modified carbon paste electrode with a new synthetic ligand : 6,7,9,10,17,18,19,20,21,22 decahydrodibenzo[ h,r] [1,4,7,11,15] trioxadiazacyclonanodecine-16,23dione (DTD)/Ag nanoparticels (AgNP).
A Conductometric Study of Complexation Reaction between Kryptofix 22DD with Yttrium(III) Cation in Some Binary Mixed Non-aqueous Solvents
The complexation process between Y3+ cation and kryptofix 22DD was studied in ethyl acetate–
dimethylformamide (EtOAc–DMF), ethyl acetate–methanol (EtOAc–MeOH), ethyl acetate–nitromethane
(EtOAc–NM) and ethyl ...
Photocatalytic degradation of reactive black 5 azo dye by zinc sulfide quantum dots prepared by a sonochemical method
Zinc sulfide (ZnS) nanoparticles (NPs) with an average particle size of 2 nm were
successfully synthesized under ultrasonic irradiation without any surfactant and high
temperature treatment. Prepared NPs were ...
