Synthesis, characterization of poly(E)-3-amino-4-((3-bromophenyl)diazenyl)-1H-pyrazol-5-ol: Investigation of antibacterial activity, fluorescence, and optical properties
(2012)
The oxidative polycondensation reaction conditions of (E)-3-amino-4-((3-bromophenyl)diazenyl)-1H-pyrazol-5-ol (Schiff base monomer) has been accomplished using NaOCl, and air O 2 oxidants in an aqueous alkaline medium. The ...
Velocity field and turbulence effects on heat transfer characteristics from surfaces with V-shaped ribs
(2012)
The flow field of smooth surfaces and surfaces with V-shaped ribs (V-SR) was studied experimentally with a Laser-Doppler Anemometry (LDA) system. In addition, heat transfer characteristics were experimentally investigated. ...
Nickel-based bimetallic nanocatalysts in high-extent dehydrogenation of hydrazine borane
(2012)
Hydrazine borane N 2H 4BH 3 (HB) is a promising chemical hydrogen storage material but its development is highly dependent on the catalyst that will be used to dehydrogenate it, that is, to hydrolyze the BH 3 group and ...
Irreversibility analysis of a compression refrigeration cycle using natural refrigerants for a sustainable future
(2012)
Irreversibility analyses of R290, R717, R718 and R744 are carried out in a compression refrigeration cycle. The effects of evaporator temperature, condenser temperature and isentropic efficiency on the irreversibility of ...
Synthesis, structural, spectroscopic characterization, and structural comparison of 3-hydroxybenzoate and nicotinamide/N,N-diethylnicotinamide mixed ligand complexes with Zn(II)
(Kluwer Academic Publishers, 2012)
The mixed-ligand 3-hydroxybenzoic acid complex of Zn(II) with nicotinamide and N,N-diethylnicotinamide were synthesized and characterized (colorless single crystals, [Zn(3-hba) 2 (H 2 O) 2 (na) 2 ] and [Zn(3-hba) 2 (H 2 ...
An artificial neural network model for the effects of chicken manure on ground water
(2012)
In the areas where broiler industry is located, poultry manure from chicken farms could be a major source of ground water pollution, and this may have extensive effects particularly when the farms use nearby ground water ...
Effect of different palatal vault shapes on the dimensional stability of glass fiberreinforced heat-polymerized acrylic resin denture base material
(2012)
Objective: The aim of this study was to determine the effect of different palatal vault shapes on the dimensional stability of a glass fiber reinforced heat polymerized acrylic resin denture base material. Methods: Three ...
Estimation of the bond grindability index from the sink-float test data of two different particulate pumices
(Taylor and Francis, 2012)
In this study, equations for estimating the Bond grindability index by the sink-float test data of pumice were developed. Primarily, the cumulative weight and porosity content of the floating fraction were determined for ...
Mixed-ligand complexes of boric acid with organic biomolecules
(2012)
Boric acid forms meta-stable complexes with biomolecules like amino and hydroxy acids and stable complexes with the diol group containing carbohydrates, vitamins, and nucleotides, yielding mono-chelate (1: 1 complex) or ...
The effects of ball filling and ball diameter on kinetic breakage parameters of barite powder
(Elsevier, 2012)
The absolute fineness of the ball diameter and the ball charge grading are important factors for the optimal operation of a ball mill. Therefore, the effects on breakage kinetics of the ball diameter and the fractional ...
